Additional information
Tensile, pure shear and planar tension are the tests inside the uniaxial group. Samples are stretched along an axis by measuring force and displacement. Cycling protocols can be integrated into the mechanical test. Mechanical and viscoelastic properties can be studied. Force is measured by means of load cells.

For determination of size distribution in the 1-1000 nm range, we offer a Photon Correlation Spectrometer (PCS) for dynamic (DLS) and static (SLS) light scattering measurements for angles in the 20-140º range and capacity of suppressing multiple scattering thanks to the 3D-cross correlation technology (down to 5% of transmission for sub-micrometer sample thickness). The instrument is equipped with a He-Ne laser and its software allows the estimation of particle size by Cumulant or CONTIN analysis. It is also possible to measure non-ergodic samples with a rotating sample holder.
For determination of size distribution in the 100-10,000 nm range we offer a Mastersizer 2000 instrument that measures by means of laser diffraction the size and distribution of particles or droplets in suspension. It is equipped with a liquid dispersing unit for small volume (Hydro 2000G) to measure emulsions, dispersions, etc. and a solid dispersion unit (Scirocco) to analyse dried powders. It is equipped with a software (windows operated) for the data processing to obtain the characteristic size (droplet, particle) and its distribution.
Customer benefits
The services provided by the unit are very relevant for product formulation and quality control. Applications include determination of the droplet/particle diameter for emulsions, suspensions and solid samples (powder) in the range of 100 nm – 2000 mm. The results are expressed in standard percentiles D(v,0.1), D(v0.5), D(v0.9), mean volume diameter (D[4,3]), mean surface diameter (Sauter mean diameter, D[3,2]), specific surface area (SSA), etc.

For this service, we offer a S3 MICRO instrument (Hecus X-ray Systems, Graz, Austria) for determinations of X-ray scattered intensity as a function of scattering angle. This instrument is equipped with a GENIX microfocus X-ray source and a FOX 2D point-focusing element (both from Xenocs, Grenoble). It can measure simultaneously at small angle (0,2º-8º) and wide angle (18°-28°).
We also offer a Quantachrome Autosorb iQ-AG equipment that provides gas adsorption/desorption curves, for the calculation of specific surface area and pore size analysis. This equipment allows the simultaneous degassing of two samples and the physisorption analysis of a third sample, at relative pressures above P/P0 > 1×10-3. The gas sorption analyzer is equipped with a cryogenic dewar for measurements until 90 hours.
Customer benefits
The services provided by the unit are very relevant for product formulation and quality control. Applications include structural characterization of materials within the nanometer range. This includes determination of symmetry, morphology, characteristic size, fractal dimension and surface area. These studies can be applied to liquid crystals, micellar aggregates, mesoporous materials, nanoparticles, proteins and nanostructured films. Also characterization of the porosity and surface area of nanoparticles, macroporous, macro/mesoporous and mesoporous materials like aluminas, silicas and other materials including M41S materials (eg. MCM-41), PMOs, KITs and many SBAs.
