Accurate detection and classification of materials, such as diseased tissues or illicit substances, is critical and misclassification can sometimes have life threatening consequences. Infrared (IR) absorption spectroscopy has been widely adopted as a simple but powerful characterisation tool, effectively producing a fingerprint of the samples’ molecular composition and aiding classification. IR absorption spectroscopy is quantitative and highly sensitive, but some measurement configurations, ...

The high energy and short wavelength of X-rays make them ideal for imaging inner features of samples at the sub-micrometer scale. Over the past twenty years, imaging techniques exploiting the phase of X-rays have progressively developed, pushed by the desire of achieving higher resolution, and to image light materials such as biological soft tissue. X-ray grating interferometry (XGI) is one such successful technique that has seen its user community growing both at synchrotrons and lab-based ...

Micro-beam Laue diffraction is a versatile probe for orientation and elastic strain in individual grains of metallic polycrystals. It can help elucidate the dependence of macroscopic material behaviour (deformation response, fatigue, fracture etc.) on microstructure, defect population, macro- to microscopic load redistribution, etc. Furthermore, it can provide quantitative validation for the crystal plasticity models used to study structural engineering alloys. The application of micro-beam ...

Aluminium hydroxide, Al(OH)3, is a lamellar material with octahedral vacancies in its layers. It has long been known that it can ‘imbibe’ LiX salts to form layered double hydroxides (LDHs) of the form [LiAl2(OH)6]X·H2O, where X is a generic anion. LDHs are important ion-exchangers, with applications in catalysis, biomedicine, and polymer science. Although size considerations should not be problematic, the incorporation of other metal ions into the octahedral vacancies in Al(OH)3 is ...

To date, the development of inert anode materials has relied on the characterisation of samples which have been removed from their operational environment at various pre-defined points of interest1. This ex situ approach can be problematic, as conventional analysis techniques typically require some form of sample preparation, ranging from simply allowing the sample to cool, to more invasive procedures such as cutting and polishing. While any material studied outside of its operational ...

Orthopaedic implants improve the quality of life of thousands of people every year, reducing pain and increasing mobility and function. In the past implants have been made of metal alloys and polyethylene, but these implants can fail, causing discomfort and, could ultimately mean further surgery. Recently implants have been developed made from irradiated and annealed ultra high molecular weight polyethylene (UHMWPE) that should have better performance. However, the molecular processes that ...
