X-Ray and Material Testing
Along with our other Research Core Facilities, we have specific scientific equipment and technical know-how for which you can also request services. These are:
Powder or Thin Film X-ray diffraction – an analytical technique used for phase identification and quantification of crystalline materials. It provides information on unit cell structure parameters and crystallographic orientation. Also used for contaminant detection and analysis. Grazing Incidence X-Ray Diffraction can also be done.
Reciprocal Space Mapping – is used to identify crystallographic orientation, composition, stress, and mismatch of heterostructures.
X-ray Reflectivity (XRR) – is used to identify film thickness, density, and interface roughness.
Nanoparticle size distribution
Particle structure (e.g. core-shell)
Specific surface area
Agglomeration behaviour of nanoparticles
Temperature range from ambient temperature up to 950 deg C
Oxidant or inert atmosphere
Dynamic and isothermal studies
Enthalpy and temperatures of melting
Cure degree (thermal and UV curing)
Glass Transition temperatures
The technique of choice for many applications that require analysing a sample for its elemental content. Typical samples include those in the environmental, metallurgical, geological, petrochemical, pharmaceutical, materials, and food safety areas. It can be applied to a variety of sample types such as aqueous and organic liquids and solids.
Porosity of the materials
Nitrogen adsorption-desorption isotherms
Surface area (B.E.T. method)
Pore size distribution
Designed to test the resistance of abrasive wear, using common flat specimens
Materials used for the testing process are: paints, coatings, metals, paper, leather, plastic, textiles, etched or printed glass, or ceramic tiles.
Used to evaluate the uniformity of thickness and degree of porosity of metallic and non-metallic protective coatings
Saturated humidity 100%
Temperature control between room temperature and +55 deg C
Corrosion standards DIN EN ISO 9227, ASTM D 117-73 ISO 6270-2, NSS, ESS, CASS
To simulate outdoor weathering, the QUV tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures.
It simulates the effects of natural sunlight and artificial irradiance using special fluorescent UV lamps in the UVA, UVB, and UVC portions of the spectrum.
Standards include: ASTM G154, ASTM D4587, ASTM D5894, EN 927-6, ISO 4892-3, ISO 11507, ISO 16474-3, ISO 12944-6, SAE J2020, J15 K 5600-7-8, AATCC TM186
Coating resistance to impact – evaluating the specimen’s elongation, cracking or peeling due to impact
The impact is produced by means of a falling weight on the specimen. The damage caused by its rapid deformation is evaluated via magnifying glass or optical microscopy
Standards include: ISO 6272, ASTM D2794-93:2019
