Solar cell materials are routinely used in many applications and many studies are ongoing which have three principle objectives. To increase the efficiency, reduce the cost of...

Carbonate liquids are characterised by low temperature and low viscosity and play an important role in molten carbonate fuel cells, battery electrolytes and, surprisingly, in...

In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent...

Mucus is a bio-gel, an opaque and slimy secretion that forms a continuous ¿blanket¿ adherent to epithelial surfaces in mammalian organs (eye, nose, conductive airways,...

The spontaneous formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures are being increasingly...

One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of...

Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These...

The exceptional high temperature mechanical properties of Ni-base superalloys has resulted in their widespread use in high temperature applications. These alloys conventionally...

Sr1-xBaxCe0.5Zr0.35Y0.1Sm0.05O3-&; (SrBCZYSm) where x = 0,0 - 0.9 are promising as intermediate temperature solid oxide fuel cell electrolyte. PXRD reveals that all of the...

In recent years, soluble derivatives of CuH prepared by non-aqueous routes have become important as mild reducing agents, one such compound, Stryker¿s reagent [Ph3PCuI]6. The...

Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to...

The study of organic ferroelectrics based on mixed-stack charge-transfer salts is currently a rapidly developing research field. These materials attract interest as highly...

This proposal aims to investigate the effect of magnetic impurities on the ALC resonance amplitude of an organic semiconductor (RRa-P3HT), to determine whether the effect can be...

On exposure to ammonia, LiBD4 and Mg(BD4)2 form the respective ammoniates, Li(11)BD4(ND3)n and Mg((11)BD4)2(ND3)6. We have identified the decomposition temperatures, kinetics...

The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the...

The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and optical properties, important climatic effects....

High entropy alloys are receiving significant attention worldwide as a new class of materials that offer unique and attractive properties. However, controversy exists over their...

Cerium dioxide is widely used as carrier on which noble metals are dispersed to act as catalysts for a range of reactions. One of the most widely used applications of this...

During recent years, the study of T=0 quantum phase transitions (QPT), the emergent scaling properties and their profound influence on physical properties at T>0 has...

Polycrystalline diamond is a man-made diamond material used for rock drilling and machining operations. Its vastly superior hardness to any other material allows it to cut...
