Electron microscope Qu-Ant-EM (FEI Titan G3)- Univ. Antwerpen, Belgium

 

DESCRIPTION OF THE FACILITY 

EMAT at UA hosts two state-of-the-art FEI Titan3 microscopes that are both aberration corrected. The resolution in TEM is as low as 50 pm and in STEM 80 pm can be reached. The accelerating voltage is 300kV, but the instruments are also aligned to operate with atomic resolution at low voltage, which is crucial when investigating soft materials. Chemical analysis can be performed by EELS. Both instruments are equipped with a monochromator that lowers the energy spread of the electrons below 0.15eV. As an alternative to EELS, a novel and highly efficient EDX system is available. The high efficiency of this EDX detector allows to record atomic resolution EELS and EDX data simultaneously. This unique feature is ideal to map the atomic positions of both heavy and light atoms. Special sample holders for electron tomography (double tilt rotation holder) as well as reconstruction software are available. In 2016, a state-of-the-art direct electron detector will be installed. This detector enables the acquisition of TEM images using a drastically reduced electron dose. This will therefore overcome current limitations and enable a whole new range of investigations for soft materials by TEM.

Electron microscope Qu-Ant-EM (FEI Titan G3) 

  • operating in TEM as well as in STEM mode 
  • lens corrected (Cs) instrument in TEM as well as in STEM 
  • operating at voltage between 300kV and 80 kV 
  • possibility to lower voltage to 60kV 
  • chemical analysis possible through EDX and EELS 
  • resolution in TEM mode 0.05 nm; in STEM mode 0.08 nm. 
  • EELS resolution below 0.2 eV (with monochromator) 
  • very high mechanical stability

Single-molecule and super-resolution fluorescence imaging - Univ. Edinburgh, UK

 

DESCRIPTION OF THE FACILITY 

The setup for wide-field single-molecule fluorescence imaging has been developed in house, and can be used for localization-based super-resolution imaging techniques such as photoactivation-localization microscopy (PALM), stochastic optical reconstruction microscopy (STORM) and related methods. 

The setup consists of a Nikon Eclipse TE2000 inverted microscope, equipped with a total internal reflection fluorescence oil-immersion objective (Plan Apochromat, magnification 60×; N.A. 1.49; Nikon). Wide-field illumination is achieved by focusing an expanded and collimated laser beam onto the back-focal plane of the objective. The resulting illuminated area has approximately 60 μm in diameter. 

Available excitation sources: 

  • 488nm CW Ar+ laser (163-C, 30 mW; Spectra-Physics)

Total Internal Reflection Microscopy (TIRM) - Forschungszentrum Jülich, Germany

 

DESCRIPTION OF THE FACILITY 

If a laser beam is totally internal reflected from a planar interface, the electric field penetrates the external phase, creating a so called evanescent wave, i. e. a wave propagating parallel to the interface with a field strength, which decays exponentially along the interface normal. The typical decay length at a glass/water interface is of the order of half the wavelength. The intensity that is scattered by a single colloidal particle located in the evanescent field monotonically decreases with the distance of the particle from the glass wall. Brownian motion of the particle normal to the interface causes intensity fluctuations, where the probability density to observe a certain value of scattered intensity is equal to the probability density of finding the particle at a certain separation distance. Thus the histogram of scattered intensities can be converted to the probability distribution of separations. The latter is used to calculate the particle/wall interaction potential from Boltzmann’s law.

3D Light Scattering - Univ. Lund, Sweden - Univ. Lund, Sweden

 

DESCRIPTION OF THE FACILITY 

The instrument from LS Instruments is used for simultaneous dynamic and static light scattering with transparent and turbid samples. It is equipped with a HeNe laser light source, wavelength λ0=632.8nm and a maximum power of 35 mW. The sample is filled into cylindrical glass cells of a diameter of 3, 5 or 10 mm or 10 mm square cells and placed in the temperature controlled index-matching bath. The scattered light is detected within an angular range of 15 to 140° by two efficient Avalanche Photo Diodes and processed by a Flex correlator in a 3D cross-correlation configuration. In aqueous samples we have access to scattering vectors 0.0034 ≤ q ≤ 0.025nm-1.The apparatus is equipped with a sample goniometer to characterize non-ergodic samples. 

The instrument is typically used for: 

  • Molecular weight determination (Zimm plots). 
  • Particle sizing 
  • Particle form factor determination. 
  • Static and dynamic structure factor measurements for strongly interacting dilute and concentrated systems. 
  • Measurements with non-ergodic samples 


Possible instrument configuration 
The instrument can be run in two different modes: 

  1. Cross-correlation: Two scattering experiments are carried out simultaneously with the same scattering volume. The signals are cross-correlated by the two detectors isolating single scattering from undesired contributions from multiple scattering. 
  2. Pseudo cross-correlation: Standard DLS and SLS measurements are performed when analyzing transparent solutions. This allows working with very short lag times and recovering the “ideal” intercept of 1 as well. 

AVAILABLE SAMPLE ENVIRONMENT

Cylindrical glass cells, diameter of 3, 5 or 10 mm, square cells with 10 mm diameter for so-called theta-2theta experiments 

Temperature Range 
Measurements can be performed at temperatures ranging from 5 to 60ºC. Temperatures below 15ºC require purging with dry air in order to avoid condensation. 

Stability 
Temperature stability typically ± 0.1°. The temperature in the index matching vat is measured on-line via a PT-100 temperature sensor within an error of ± 0.05ºC. 

Pressure 
Measurements are performed at ambient pressure. 

Magnetic field 
Measurements are carried out without magnetic field.

TYPICAL MEASUREMENTS 
The CGS-3 instrument is designed to perform simultaneous measurement of static and dynamic light scattering parameters, without the need to make an adjustment to optimize the system for DLS or SLS. The lower and upper concentration limits are determined by the physical properties of the particle (referactive index, radius,...). The data are then analysed by any appropriate algorithm, using ALV-Fit and plot software. 

PARAMETERS MEASURED 
Dynamic light scattering 

  • Hydrodynamic size 
  • Diffusion coefficient 
  • Polydispersity index 
  • Particle size distribution 


Static light scattering 

  • Molecular weight 
  • Radius of gyration 
  • 2 nd virial coefficient 

 

AVAILABLE SAMPLE ENVIRONMENT

The temperature of the cell area can be controlled from -6°C to 120°C. At moderate temperature measurements (RT) toluene is used as index matching fluid. For high temperature experiments (T >50°C), cis-decalin is used.

Diffusing Wave Spectroscopy - Univ. Lund, Sweden

 

DESCRIPTION OF THE FACILITY 

The instrument is used for characterization of extremely turbid samples and is equipped with diode-pumped solid-state laser (wavelength of 660 nm) with a maximum power of 70 mW. The apparatus is implemented with a “Two-Cell Echo Technique” which allows reducing measurement times down to only a few minutes even for slowly relaxing and solid-like materials. The sample is filled into squared glass cells of 1 – 10 mm and placed in a temperature controlled sample environment (15-70ºC). The scattered light is detected with two efficient Avalanche Photo Diodes in transmission and processed by a multi-tau/linear correlator using pseudo-crosscorrelation as well as echo measurements. Also possible are experiments using backscattering geometry as well as CCD camera-based multispeckle measurements. The equipment runs with a powerful software solution (LS-Instruments, Fribourg, Switzerland) for data acquisition and analysis (combined correlation-echo measurements, single-, multi-speckle analysis, user defined multi-run scripts, online microrheology analysis and full data access). 

The instrument is typically used for: 

  • Determination of mean square displacement (values as small as 1 nm measurable depending upon particle size) 
  • Determination of average particle size in concentrated suspensions. 
  • DWS-based microrheology

Evanescent Wave Dynamic Light Scattering (EWDLS) - Forschungszentrum Jülich, Germany

 

DESCRIPTION OF THE FACILITY 

If a laser beam is totally internal reflected from a planar interface, the electric field penetrates the external phase, creating a so called evanescent wave, i. e. a wave propagating parallel to the interface with a field strength that decays exponentially away from the interface. The typical decay length at a glass/water interface is of the order of half the wavelength. Using an evanescent wave as the illumination source for a scattering experiment will therefore provide scattered intensity only from a very narrow region close to the interface. This is exploited to study near-wall particle dynamics with EWDLS. Here we use a three axis goniometer to decouple the scattering vector components parallel and normal to the interface, which allows to study the particle mobility along the wall and normal to it independent of each other.

Heterodyne Dynamic Light Scattering (HDLS) under shear - Forschungszentrum Jülich, Germany

 

DESCRIPTION OF THE FACILITY 

The heterodyne dynamic light scattering (HDLS) measures spatially resolved flow velocities in the gap of a Couette shear cell. The analysis of the velocity profile of complex fluids addresses to effects like shear-banding and wall-slip, not known for Newtonian fluids. 

The optical set-up is based on a well known differential Laser-Doppler velocimeter as used mainly with single particle detection in turbulent two phase flows. The light of a Krypton ion laser is split into two beams of equal intensities, which are then focussed into a small volume in the gap of a transparent Couette cell using a photo lens. Light of both beams is scattered by the sheared fluid. Due to the different scattering vectors q related to the two incident beams the frequency of the scattered light is differently shifted (Doppler effect). The interference of this scattered light results in an intensity oscillating with the beat frequency, which is then measured by analysing the intensity autocorrelation function. To adjust the position within the gap the photo lens can be moved along the optical axis by a motorized linear stage. With this special kind of heterodyne light scattering set-up the resulting Doppler frequency is independent of the direction of the observer. Therefore we are able to choose this relatively simple light path in the difficult geometry of the Couette shear cell with many curved surfaces. 

The shear cell used in this set-up can be assembled from an outer and inner cylinders with different diameters (dout=48 mm and din=43, 44, 45, 46 mm, respectively) with resulting gaps from 1 to 2.5 mm. The cell has a height of 50 mm. The inner and/or the outer cylinder can be driven by a DC servo motor which together with a gear transmission and the choice of a gap allows shear rates from 0.01s-1 to above 1000s-1 to be applied. The intensity of the Krypton ion laser with a wavelength of 647nm and a nominal power of 500mW is typically attenuated to less than 50mW. The scattering at an angle of 13° corresponds to an absolute value of q of . The cross section of the laser beams defines the size of sample volume to about 20*100 m, when the beams are crossed at an angle of 26°. The intensity autocorrelation function is recorded using an ALV-FastCorr Linear Correlator with 256 channels. The sample time can be adjusted in the range of 75 ns to 408 s. For longer sample times the correlation function can be calculated by software. An accumulation time of a few seconds is usually sufficient to determine the frequency in the measured correlation function.

Multiangle 3D-Goniometer - Univ. Lund, Sweden

 

DESCRIPTION OF THE FACILITY 

The instrument allows time-resolved measurements of dynamic and static light scattering in transparent and turbid samples using the technique of 3D cross-correlation at four angles simultaneously. The apparatus is equipped with a diode-pumped solid-state laser (wavelength λ0=532 nm) with a maximum power of 200 mW. The sample is filled into cylindrical glass cells of a diameter of 3, 5 or 10 mm or square cells with diameter 10 mm and placed in the temperature controlled index-matching bath. The scattered light is detected within an angular range of 10 to 150° by two photomultiplier tubes at each angle and processed by a Flex correlator in a 3D cross-correlation configuration. Thus four intensity correlation functions are obtained simultaneously, one for each scattering angle measured. In aqueous samples we have access to scattering vectors 0.0027 ≤ q ≤ 0.031nm-1. 

The instrument is typically used for: 

  • Molecular weight determination (Zimm plots). 
  • Particle sizing via hydrodynamic radius. 
  • Particle form factor determination. 
  • Static and dynamic structure factor measurements for strongly interacting dilute and concentrated systems. 


The instrument is run in cross-correlation mode: Two scattering experiments are carried out simultaneously with the same scattering volume. The signals are cross-correlated by the two detectors isolating single scattering from undesired contributions from multiple scattering. 

AVAILABLE SAMPLE ENVIRONMENT

Cylindrical glass cells, diameter of 3, 5 or 10 mm, square cells with 10 mm diameter 

Temperature Range 
Measurements can be performed at temperatures ranging from 5 to 60ºC. Temperatures below 15ºC require purging with dry air in order to avoid condensation. 


Stability 
Temperature stability typically ± 0.1°. The temperature in the index matching vat is measured on-line via a PT-100 temperature sensor within an error of ± 0.05ºC. 


Pressure 
Measurements are performed at ambient pressure. 


Magnetic field 
Measurements are carried out without magnetic field.

Thermal Diffusion Forced Rayleigh Scattering (TDFRS) - Forschungszentrum Jülich, Germany

 

DESCRIPTION OF THE FACILITY 

Measurement principle: 
A grating created by the interference of two laser beams is written in the sample. A small amount of dye, present in the sample, converts the intensity grating into a temperature grating. After switching on the laser, a refractive index grating is formed in the solvent on the milli second time scale. On a longer time scale, the colloids contribute to a change of the refractive index grating through thermal diffusion, where they either move to the cold or warm regions of the grating. Both gratings contribute to a combined refractive index grating that is read out by diffraction of a third laser beam. Analysing the time dependent difraction efficiency, three transport coefficients can be obtained: the thermal diffusivity Dth, the translational diffusion coefficient D, and the thermal diffusion coefficient DT. The ratio of the thermal diffusion coefficient and the translational diffusion coefficient allows the determination of the Soret coefficient ST. 

For aqueous systems, the use of added dye to the sample can be avoided, using an infra red writing beam. The water is now heated, without any added dye, through the excitation of vibrational states. 

SAMPLE REQUIREMENTS 
Binary liquid mixtures, polymer solutions or colloidal dispersions (preferably in organic solvents). The solutions should be transparent. The radius of the colloidal particles should be below 100 nm. A complete measurement including the measurement of the refractive index with concentration and temperature requires approximately 10-15 mL solution.

Ultra Small Angle Light Scattering - Univ. Lund, Sweden

 

DESCRIPTION OF THE FACILITY 

The instrument is used for simultaneous dynamic and static light scattering at ultra-small angles using a CCD camera. The scattered light is detected from 0.3º to 6º, corresponding to length scales from a few hundred nanometers to a fraction of a millimetre. Time resolved static measurements with a time resolution of approx. 100 msec. Multispeckle correlation functions are processed in real-time, thereby allowing measurements of a set of intensity autocorrelation functions at different q-values using measurement times that are comparable to the longest correlation time. A multitau correlation scheme is adopted (delay time space quasi-lograrithmically), requiring thereby less data storage and processing time. This allows one to calculate time- and pixel-averaged correlation functions in real time. Multiple exposure times are used in order to optimize the mean intensity level for all scattering vectors. The instrument is equipped with a HeNe laser light source with a wavelength of 632.8nm and a maximum power of 35 mW. The sample is filled into squared glass cells with path lengths ranging from 10 micrometer to 1 mm and placed in a temperature-controlled sample environment. The instrument is designed to study both ergodic and non-ergodic samples 

The apparatus is typically used for: 

  • Particle sizing. 
  • Particle form factor determination. 
  • Static and dynamic structure factor measurements for strongly interacting dilute and concentrated systems. 
  • Time resolved phase separation kinetics and structural evolution of large length scales 


Possible instrument configuration 
The actual set-up allows to measure at a q range from 6·10-5 to 1.1·10-3 nm-1. 

AVAILABLE SAMPLE ENVIRONMENT

NEUTRON SCATTERING INSTRUMENTS

Backscattering Spectrometer (SPHERES) - JCNS, Munich, Germany

 

DESCRIPTION OF THE FACILITY 

WSPHERES is a third generation backscattering spectrometer that uses focusing optics and a phase-space transform chopper, which is responsible for very high flux. In combination with Argon filling the world leading signal to background ratio of 1500:1 is possible. A novel resonance free linear drive serves the dynamic range of ±31 µeV resulting in the broad time scale of 200-5000 ps. Therefore, SPHERES is ideally suited to study polymers, proteins, etc. 

Typically in the case of polymers 4h per temperature is enough to achieve sufficiently high signal to noise ratio. In the standard configuration a temperature range of 3K - 600K is possible. Lower or higher temperatures can be achieved by an oven or a special cryostat on request.

Diffuse Neutron Scattering (DNS) - JCNS, Munich, Germany

 

DESCRIPTION OF THE FACILITY 

High-flux time-of-flight spectrometer with polarization analysis 

DNS is a versatile diffuse scattering cold neutron time-of-flight spectrometer with polarization analysis at FRM II. This allows the unambiguous separation of nuclear coherent, spin incoherent and magnetic scattering contributions simultaneously over a large range of scattering vector Q and energy transfer E. With its compact size DNS is optimized as a high intensity instrument with medium Q- and E- resolution. With the increased flux and efficiency at FRM II, DNS becomes ideal for the studies of complex spin correlations, such as in highly frustrated magnets and strongly correlated electrons via neutron polarization analysis. DNS also represents a powerful instrument for the soft condensed matter community for the separation of nuclear coherent scattering from often dominating spin incoherent scattering background in a wide-angle diffraction experiment.

Magnetic Reflectrometer (MARIA) - JCNS, Munich, Germany

 

DESCRIPTION OF THE FACILITY 

The neutron reflectometer MARIA with polarization analysis has been designed for the investigation of thin magnetic layered structures down to the monolayer scale and lateral structures. The reflection of polarized neutrons allows to determine individually the density and the modulus and the direction of the magnetization vector of buried layers. 

MARIA is optimized for layer thicknesses between 3-300 Å and lateral structure sizes from nm to µm sizes. Consequently the instrument is designed for small focused beam and sample sizes of 1 cm2 at λ=4.5 Å (available: 4.5Å < λ < 40Å) in a vertical orientation with a maximum incident angle of 180° and outgoing angle from -14° to 100°. Beside the above described reflectometer mode with good resolution in the horizontal scattering plane, MARIA can be used in the GISANS mode with additional resolution in the vertical direction. The latter mode allows one to measure lateral structures down to the nm scale.

Neutron Spin Echo Spectrometer (J-NSE) - JCNS, Munich, Germany

 

DESCRIPTION OF THE FACILITY 

Neutron spin-echo (NSE) spectroscopy is a time-of-flight technique where very small velocity changes of the neutron during the scattering process are detected.
Neutron spin-echo spectrometers, with its very high energy resolution, allow for the analysis of slow motions (i.e. some 1-100 ns) on large and on intermediate length scales (of the order of 0.5-20 nm). They measure the intermediate scattering function S(q,t), the Fourier transform of the scattering function S(q,ω). The relevant resolution parameter is the maximum achievable Fourier time. 
The J-NSE spectrometer has a very low background with a good stability of the instrument, allowing to measure tiny effects. As an example, internal motion of proteins in solution can be measured, or the dynamics of molecules or membranes close to a surface under grazing incidence. 

Sample size: Flat cells, size 30x30 mm2. Thickness depending on degree of deuteration 1-4 mm

Single crystal diffractometer for biological macromolecules (BIODIFF) - JCNS, Munich, Germany

 

DESCRIPTION OF THE FACILITY 

The monochromatic single crystal diffractometer BIODIFF is a joint project of the FRM II and the Forschungszentrum Jülich (FZJ). Using a pyrolytic graphite monochromator (PG002) the diffractometer BIODIFF will be able to operate in the wavelength range of 2.4 Å to 5.6 Å. A neutron velocity selector is employed to remove higher order wavelength contaminations. The main detector is a cylindrical neutron image plate with online read-out. An auxilliary detector is foreseen for a fast alignment of crystals and additional detection abilities. This auxiliary detector consists of a CCD-camera equipped with a LiF/ZnS neutron sensitive scintillator. The main advantage of BIODIFF is the possibility to adapt the neutron wavelength to the size of the unit cell of the sample crystal while operating with a clean monochromatic beam keeping the background level low. It is therefore well suited for the structural analysis of biological macromolecules forming crystals with large unit cells.

Small Angle Scattering 2 (KWS-2) - JCNS, Munich, Germany

 

DESCRIPTION OF THE FACILITY 

The KWS-2 represents a high-intensity 40m long SANS instrument with a typical Q range, from about 10-4 to 0.5 Å-1, which can be explored by combining the classical pinhole mode (wavelength range λ=4.5÷20 Å, sample-to-detector distance 1÷20m) and focusing optics elements (MgF2 neutron lenses). It is dedicated to investigation of mesoscopic structures and structural changes due to rapid kinetic processes (time resolution 100ms) in soft condensed matter, chemistry and biology. The maximal flux is 3x108 n / cm2 s reached by using a large beam size (50x50 mm2) and a wavelength spread Δλ/λ=20%. 
A sample size of 10x10mm2 (in quartz Hellma cells, 1mm and 2mm in thickness) is typically used; optionally, for gaining intensity, larger samples (using special round quartz Hellma cells) up to 5cm in diameter, can be used with neutron lenses.

Interfacial Stress Rheometer - K. Univ. Leuven, Belgium

 

DESCRIPTION OF THE FACILITY 

The Interfacial Stress Rheometer (ISR) is a unique instrument that provides an accurate and quantitative method to measure the shear properties of an interface. The method is a major improvement compared with traditional rotational rheometers that lack sensitivity to probe interfacial properties. 

DEVICE SPECIFICATIONS 
The ISR applies a controlled stress to an interface by creating a magnetic field onto a magnetized rod causing a displacement. This induces a shearing deformation on the interface. The resulting strain is measured in real time by monitoring the position of the rod onto a CCD detector. 

The instrument can be operated in two different modes : creep compliance where a steady stress is applied and dynamic testing where sinusoidal stresses at variable frequencies are applied. 

Dynamic moduli lower limit : 0.001 mN/m 
Frequency range : 0.05 rad/s to 10 rad/s 
Strain range : 0.0003 to 1 

CONFIGURATIONS 
The instrument is equipped with KSV troughs for insoluble monolayers. Measurements can be performed either at the air/water or oil/water interface.

Rheo-DSC - K. Univ. Leuven, Belgium

 

DESCRIPTION OF THE FACILITY 

The RheoDSC device is a hybrid apparatus containing both a constant stress rheometer (AR-G2) and a calorimeter (DCS Q2000) that allows simultaneous measurement of rheology and calorimetry on the same sample. Moreover, the application of flow during DSC experiments opens new possibilities to investigate flow-induced transitions. 

The RheoDSC combines an AR-G2 rheometer and a Q2000 calorimeter. A special design allows a rheological geometry to enter the DSC furnace with minimum heat losses. The fixation inside the DSC cell and a specially designed heat break geometry establish the needed rotor-stator for rheology experiments. Both are engineered to minimize thermal lagging and to maintain calorimetric precision with good mechanical stability for high precision rheology. In principle, the device characteristics are similar to those of the individual stand-alone components (AR-G2 and Q2000). 

The device requires specially designed tools such as heat conducting and heat break geometries (polyamide-imide) of 5 mm diameter. 

TYPYCAL MEASUREMENTS 

Reliable coupling of the information from heat flow and rheological data during transformations 
Quiescent crystallization: correlation between viscosity hardening function Γ=η/η0 and degree of crystallinity ξ 

Crystallization in shear flows: Effect of shear pulse on crystallization behavior 

Crystallization in oscillatory flows: Effect of frequency on crystallization behavior 

Sample curing and crosslinking: Fast and complete characterization of processes

CaBER (Thermo Haake)- Univ. Leuven, Belgium

 

DESCRIPTION OF THE FACILITY 

The Capilary Breakup Extensional Rheometer (CaBER) provides valuable information about the material's extensional properties that rotational rheometers simply cannot provide. That’s because materials that behave similarly in a shearing flow often behave very differently in an extensional flow. With the CaBER instrument, stringiness, filament breakup-time and extensional viscosity can now be quantified to quickly optimize your fluid formulations for either industrial or research applications. 

DEVICE SPECIFICATIONS 
The CABER uses a laser micrometer to monitor the diameter of a thinning filament. The diameter versus time data is the raw output of the instrument and will serve a the appropriate input for a software package that will determine the rheological parameters. The shear viscosity range that can be used in this instrument is between 10 and 106 mPa.s. The Hencky strain that can be achieved goes up to 10 whereas the imposed strain rates vary between 10-5 and 10 s-1. The diameter resolution that can be measured accurately by the laser monitor is 10 micron. 

CAMERA SETUP 
A Photron Fastcam SA-2 high speed camera in combination with a Navitar 12x zoom objective or a tube lens with different Olympus microscopic objectives can be used to visualize the break-up. In comparison with the laser micrometer, the camera setup can achieve a higher diameter resolution and can give more information about the thinning dynamics, since the entire filament is visualized while the laser micrometer only detects the value of the middle diameter. 

DATA ANALYSIS 
Available models can be either fitted to extract rheological parameters or diameter versus time data can be converted to an apparent extensional viscosity where the strain is defined by the diameter of the filament and hence varies with time. Other qualitative information that can be obtained from these data 
are time-to-breakup and from the shape of the curve the ‘stringiness’ of the fluid. 

AVAILABLE SAMPLE ENVIRONMENT

The measurement temperature can be controlled by using a standard thermostat bath.

Electrospinning device - K. Univ. Leuven, Belgium

 

DESCRIPTION OF THE FACILITY 

The electrospinning device uses electrical forces to produce fibers with nanometer scale diameters and high surface to volume ratios from different materials such as polymers, composites and ceramics. 

DEVICE SPECIFICATIONS 
Due to a high voltage electric field, the electrical forces at the surface of a polymer solution or melt overcome the surface tension and cause an electrically charged jet to be ejected. After evaporation of the solvent, thin and continuous fibers that reach diameters of the order of nanometers and that consist of highly aligned polymer strands are obtained. Voltages between 0 and 25 kV can be applied. A Harvard infusion pump and specific nozzle diameters are used to control the flow rates. The inter-plate distance can be varied within the working area dimensions. 

HIGH SPEED CAMERA 
In-line observation of the spinning process is possible using a new optical setup with a Photron Fastcam SA-2 high-speed camera and a 3D precision positioning setup. 

TYPICAL APPLICATIONS 

  • Development of new ultra-high strength hydrogel membranes as wet wound dressing. 
  • Design of new morphologies of nano-structured fillers and compounds. 
  • Development of thin nanofibers from renewable resources.

AVAILABLE SAMPLE ENVIRONMENT

Due to recent developments at IME technologies, it will be possible to control the cabin temperature in the range of 15-50 °C and cabin humidity in the range of 10-90%.

Interfacial Stress Rheometer - K. Univ. Leuven, Belgium

 

DESCRIPTION OF THE FACILITY 

The Interfacial Stress Rheometer (ISR) is a unique instrument that provides an accurate and quantitative method to measure the shear properties of an interface. The method is a major improvement compared with traditional rotational rheometers that lack sensitivity to probe interfacial properties. 

DEVICE SPECIFICATIONS 
The ISR applies a controlled stress to an interface by creating a magnetic field onto a magnetized rod causing a displacement. This induces a shearing deformation on the interface. The resulting strain is measured in real time by monitoring the position of the rod onto a CCD detector. 

The instrument can be operated in two different modes : creep compliance where a steady stress is applied and dynamic testing where sinusoidal stresses at variable frequencies are applied. 

Dynamic moduli lower limit : 0.001 mN/m 
Frequency range : 0.05 rad/s to 10 rad/s 
Strain range : 0.0003 to 1 

CONFIGURATIONS 
The instrument is equipped with KSV troughs for insoluble monolayers. Measurements can be performed either at the air/water or oil/water interface. 

TYPICAL MEASUREMENTS 
A broad spectrum of measurements can be performed with this instrument. For instance examination of phase transitions, prediction of emulsion and foam stability, monitoring surface gelation and network formation in real time, continuous monitoring of adsorption ..., are examples of possible measurements. 

A LabView-based software program allows the user to control the desired stresses.

AVAILABLE SAMPLE ENVIRONMENT

Temperature control can be achieved by means of a recirculating fluid bath that allows temperatures from 5°C up to 60°C.

RHEOLOGY // RHEOSTRUCTURAL TECHNIQUES

Counterrotating - K. Univ. Leuven, Belgium

 

DESCRIPTION OF THE FACILITY 

The counterrotating is a special designed rheometer by Paar Physica, based on the MCR and DSR 300, with two rotating drives instead of one. A stereomicroscope and a camera, with some complementary optical components, are also installed so observations in a stationary plane (because of the counterrotating drives) in a shear flow can be made. 

DEVICE SPECIFICATIONS 
The device combines the technology of MCR300 and DSR300 units. The software, based on US200 software, is modified to control both devices at the same time. 

GEOMETRIES 
A couette cell and a parallel plate setup ( 50), both made in glass, are available. With the parallel plate setup, measurements can be made with gap widths of only a few 100 µm up to as much as 5 mm since a glass cup surrounds the bottom plate and holds the sample in place. 

MICROSCOPE AND CAMERA 
The microscope is a WILD M5A stereo microscope, necessary for the long working distance. The camera is a BASLER A301fc color camera. StreamPix software makes it possible to control the camera and make digital pictures. 
The microscope can practically be used to observe particles as small as 10 µm. The set-up can easily be repositioned such that observations in the velocity gradient as well as in the vorticity plane can be made. 

TYPICAL MEASUREMENTS 
Drop deformation in steady shear flow, during start-up or relaxation in various media, confined droplet dynamics, solid particle rotations in various media, migration effects, hydrodynamic interactions between two or more particles,... can be studied with this set-up. 
Due to good control of the rotational speed and width between the plates, accurate quantitative measurements are possible within a wide variety of conditions. 

AVAILABLE SAMPLE ENVIRONMENT

The set-up is located in an air-thermostated room for temperature control.

X-RAY SCATTERING INSTRUMENTS

cSAXS - X-ray scattering and imaging - SLS, PSI, Villigen, Switzerland

 

DESCRIPTION OF THE FACILITY 

The cSAXS beamline offers a portfolio of non-destructive techniques for determining nanoscale properties of samples in different combinations of spatially averaging and spatially resolved imaging techniques. Common to all techniques is the use of X-ray synchrotron radiation in the energy range from 6 to 18 keV corresponding to 2 – 0.7 Å wave length, emitted from a brilliant undulator source and detected from a single photon counting system of the PILATUS 2M type. 

Available techniques 
The cSAXS beamline is quite versatile in terms of experimental setups and sample environments. Most experiments can be grouped in three categories: 
1. scanning SAXS as imaging technique of average nano-scale structures: The samples are raster scanned in two dimension through the X-ray beam of typically 25 µm × 10 µm spot size. At each point a 2D SAXS data frame is recorded. In this way typically a few 10’000 SAXS data frames are recorded per sample and hour. From the data abundance and orientation in the few to few hundred nanometer range can be deduced, averaged over individually illuminated spots but spatially resolved over extended sample areas of square millimeters or centimeters. 
In this way for example orientation effects in cast polymer samples, abundance of distinct additives like carbon nano tubes or alignment effects by in-situ stretching of foils can be investigated. 
2. time-resolved SAXS as spectroscopic finger print of samples: With the brilliant undulator source and the fast framing PILATUS detector SAXS data frames can be recorded at rates of up to 30 Hz, when focusing on a small scattering angles up to 300 Hz. This allows following structural changes with sub-second time resolution. In this way for example in-situ crystallization, structural changes as a function of temperature or laser induced structural changes can be investigated. The SAXS data are typically recorded for an ensemble average given by the size of the by the X-rays illuminated area that may range from 25 µm × 10 µm up to and beyond 0.5 mm × 0.5 mm. 
3. Coherent diffractive imaging as high resolution imaging technique: For roughly cylindrical samples of up to 50 µm in diameter the 3D structure can be measured in an X-ray computed tomography experiment with typically 150 nm resolution. In this way for example the pore structure in a filament or the distribution of particles in a polymer matrix can be investigated non-destructively. 

Possible instrument configuration 
Scanning SAXS and coherent diffractive imaging can be performed in 2D imaging and 3D tomography mode. Static and time resolved SAXS can be performed in a large variety of user specific experiments. The beamline scientists should be contacted to discuss the possibilities and feasibility of experiments. 

A small chemistry lab including fume hood, basic lab equipment like some glassware, desiccator, heating plate and oven and stereo microscope is exclusively available for users of the cSAXS beamline. A high resolution microscope with camera is available as well. 
For further details please check our web pages and contact one of the beamline scientists in charge. 

http://www.psi.ch/sls/csaxs/

 

AVAILABLE SAMPLE ENVIRONMENT

The advantage of using hard X-rays in the energy range from 6 to 18 keV is, that the samples can be kept in air, i.e., an evacuated sample environment is not necessary and a large range of sample environments is compatible with the X-ray measurememts. For SAXS on capillaries a temperature controlled holder for 10 capillaries is currently commissioned for temperatures in the range from 10 to 100 ºC with about 0.2 ºC. 
For 2D scanning SAXS several extended, flat samples can be mounted together on a single holder and measured in a pre-programmed way. 
For coherent diffractive imaging cold nitrogen gas cooling down to 150 K is available to reduce radiation damage in X-ray sensitive polymers. 
Different sample environments brought by users can be accommodated for in-situ experiments. Please contact one of the beamline scientists in advance to discuss the possibilities.

Small/Wide Angle X-Ray Spectrometer, Univ. LUND, Sweden

 

DESCRIPTION OF THE FACILITY 

This instrument combines a X-ray focusing optics with a block collimator which produces an intense, monochromatic primary beam. The primary beam is focused through the sample allowing fast measurements of the scattering pattern, even from samples with low contrast. The scattering signal is detected by a CCD camera for SAXS and a 2D imaging plate detection system for WAXS. The apparatus is implemented with a SAXSess camera using a X-ray generator (PANalytical, PW 3830) with a sealed copper tube. The X-ray generator offers a maximum power of 4.0 kW and an operating range of 20-60 kV and 10-100 mA. A Göbel mirror and a Kratky block collimation system (line-shaped beam) is used to convert the divergent polychromatic X-ray beam into a focused line shaped beam of Cu-Ka radiation. Holders for liquid and solids are available. The instrument design makes it possible to investigate particles length scales from 0.25 nm (thanks to the wide angle extension system) up to 40 nm. Thus, q values range from ≤ 0.077 nm-1 (corresponding to a Bragg value ≥ 82 nm) up to ≈ 8 nm-1 (SAXS) and ≈ 29 nm-1 (SWAXS). 

The apparatus is typically used in a wide variety of fields such as self-assembling surfactant systems, microemulsions, particle sizing of suspended nano-powders or catalysts (determination of suface per volume) among others. 

AVAILABLE SAMPLE ENVIRONMENT

Thermostatted capillaries and solid sample holders 

TEMPERATURE RANGE 
Measurements can be performed at temperatures ranging from -30 to 120ºC (High temperatures with solid sample holder only). 

PRESSURE 
Liquid samples at ambient pressure (sealed capillaries), solid samples in vacuum (down to 10-2 bar). 

MAGNETIC FIELD 
Measurements are carried out without magnetic field.
