There are few studies on the effect of pressure on ionic liquids; however, there are indications that, at pressures around 1.0 GPa, these systems undergo a significant change in...

We have discovered a novel type of quantum spin liquid in a hexagonal lattice of Ru5+ dimers in Ba3ZnRu2O9, where any traces of the Curie tail or glassy behavior have not been...

We use SANS to study synthesis of interpenetrating polymer network in supercritical CO2 in situ at sans2D. The initial system contains an inorganic polymer network, hydrophilic...

The organic-inorganic perovsike (OIP) methylammonium lead iodide, MAPbI3, has been identified as a promising candidate for the development of efficient solid-state solar cells....

Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This...

Spin ice materials are a class of compounds with exotic magnetic properties, resulting from the frustration. Magnetic monopoles have been detected at low temperature; manifest...

Supercritical CO2 is an interesting medium for supercritical fluid extraction of aromatic molecules, due to the low temperatures and pressures needed to the process. Methanol is...

We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our...

We have created very short intermolecular hydrogen bonds in benzoic acid "dimers" by co-crystallisation of these into molecular complexes with the proton sponge...

TiCl4 forms a molecular structure containing isolated tetrahedral molecules on cooling to 248 K. The freezing pressure of TiCl4 is 0.05 GPa (500 atm). Single crystal growth...

While Y(Mn1-xAlx)2 (x<0.02) is seen as a system of AF coupled local Mn moments (T<110K), alloys with 0.02

At ambient pressure and temperature TiCl4 is a fuming yellow liquid. On cooling it forma a solid composed of essentially isolated tetrahedral molecules; the same structure is...

Ba3BiIr2O9 and Ba3BiRu2O9 undergo very unusual structural transitions at 74 and 176 K respectively, with instantaneous negative thermal expansion of up to 1% in the Ir compound....

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is...

Shale swelling is particularly problematic in the oil and gas exploration sector, as environmentally friendly water based muds are invariably used during drilling operations to...

Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of...

The Vanadium spinels provide ideal systems to study the interactions between spin, lattice and orbital degrees of freedom. The magnetic V3+ ions are antiferromagnetically...

The proposal develops recent observations on spin-lattice coupling in incommensurate materials (objective - measure influence of applied field on evolution of structural...

Supercritical (sc) fluids have unique properties that have led to a rich variety of applications including production of essential oils and pharmaceutical products, green...
