Intergranular stresses are generated in polycrystalline material due to anisotropic deformation during monotonic and cyclic loading. Such generated intergranular stresses can...

Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of...

TOF-Neutron Diffraction experiments conducted on significant archaeological findings from the pre-roman Ligurian settlement of Guardamonte (Monte Vallassa) have shown unusual...

Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the...

Compounds of ethanol and ammonia have been known for over a century but no structural characterisation has ever been carried out. These materials allow us to examine a range of...

One class of bioactive lipopeptides produced by Bacillus subtilis, fengycin, has strong surfaceactivity and interesting antifungal property with low hemolytic activityTo gain...

Organic ferroelectrics are in the focus of current research because their potential applications as a material to address global challenges. These lightweight, flexible and...

We propose to use Polaris to record powder neutron diffraction data for the oxygen deficient double perovskite Sr3SbO5.5 as a function of temperature to establish the...

With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously...

This proposal is part of a new project based on understanding the formation of gels in suspensions of partially oxidised cellulose nanofibrils with small amounts of salt or...

Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

We ask for 8 days of beam time on CRISP to study the absorption and desorption of hydrogen and deuterium in Ti/Mg/Pd trilayer samples. Our specific objective is to understand in...

The aim of the proposed experiment is to carry out a series of SANS measurements on chain-grafted silica nanoparticles prepared in our laboratory. In this experiment we plan to...

The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD...

Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for...

Benzene is probably the most studied compound in the history of organic chemistry. Whenever a new experimental technique or theoretical method is being developed most of the...

INVAR behaviour is the property of having zero thermal expansion over a given temperature range; something very important for certain engineering applications, and very...

Flexible functional materials are important candidates of current research, because of their potential applications in plastic electronics. Organic ferroelectrics are one of...

In recent years, our team has discovered three new phases of ice: ices XIII, XIV and XV. On the basis of calorimetric data and some limited diffraction data collected on GEM we...

The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen...
