There are great energy costs associated with the separation of the light olefins (ethylene and propylene) from mixed hydrocarbon gas feeds. These olefins (obtained from natural...

The one dimensional material In2VO5 contains frustrated zigzag chains of corner sharing V 4+ (S = 1/2) square based pyramids interspersed with sheets of edge sharing InO6...

The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from three differently deuterated versions of 8CB....

The behaviour of multiple polymers in competition for colloidal silica has previously been investigated in our group using solvent relaxation nuclear magnetic resonance. We...

The high pressure perovskite PbCrO3 has been known since the 1960’s but the electronic properties were controversial. The average structure is a cubic Pm-3m perovskite but a...

Bacterial and fungal infections of cereal crops pose a considerable risk to global food security. Typically plant pathogens are controlled through the use of chemical agents...

The development of high energy density and high efficiency hydrogen storage materials is widely considered to be one of the most challenging barriers to the adoption of fuel...

The analysis of Indo-Persian arms and armour in the Wallace Collection and the identification of those made from wootz crucible steel have been the principal aims of a long-term...

Neutron powder diffraction studies of layered rock salts LiCo0.1Mn0.1Ni0.8O2 and LiCo0.1Mn0.1Ni0.8O2-d

The asphaltene fraction of crude oil is defined by its solubility parameters (insoluble in n-heptanebut soluble in toluene). Changes in conditions (temperature, pressure,...

Recently insulator-metal transition in Pr0.7Ca0.3MnO3 was observed at P = 0.5 GPa, implying a change in magnetic ground state, which was initially a pseudo-CE AFM one. In later...

The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 type structure has attracted a lot attention in recent years due to geometrical frustration...

While traditionally considered competing phenomena, recent theoretical and experimental work has shown that, when juxtaposed, there is a wealth of proximity effects in...

The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong...

Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex...

An uncommon oxygen absorption/desorption behavior for cobalt oxide YBaCo4O7+d was found[Karppinen et al. Chem Mater 18 2006 490]. Y114 absorbs and desorbs oxygen up to d = 1.5...

We request 4 days to collect high-resolution structural high-pressure data on two zeolites - zeolite A and EMC-2. Our previous theoretical findings from geometric simulation...

Lipopolysaccharides are amphiphilic macromolecules indispensable for the growth and the survival of Gram-negative bacteria, one of the most diffuse classes of pathogenic...

We propose to use the OSIRIS spectrometer to measure the inelastic magnetic scattering on the newly discovered heavy Fermion compound Ce3Co4Sn13. This compound has one of the...

A new class of materials called Topological Crystalline Insulator(TCI) has been recently proposedtheoretically and subsequently, SnTe has been discovered to exhibit all the...
