We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the...

The Shastry-Sutherland lattice (SSL) can be described as a 2D square lattice built up from a network of dimers disposed orthogonally and has been observed in SrCu2(BO2)3....

We request four days of GEM time to collect full patterns on PbZr1-xTixO3 (PZT) with different compositions at room temperature for Pair Distribution Functions (PDF) analysis....

There has been significant interest in the oxide ion conducting material La2Mo2O9 as a new electrolyte after initial reports of conductivity as high as that of YSZ at lower...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed...

The newly discovered AxFe2-ySe2 (A=K,Rb,Cs) compounds have attracted great interests because of their parent compounds are insulators instead of being metallic [2-6]....

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...

Ca3Co2O6 is an unusual system, with a highly anisotropic magnetic behaviour and a series of regularly spaced steps in magnetisation appearing at low temperatures in a magnetic...

Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood...

We propose to characterize the core material of two Renaissance Statues. The results of this study will provide us with quantitative information on the mixture of material for...

Oxalyl chloride, which is a liquid at RT, forms a disordered phase (I) on cooling to 260 K. This phase is unstable with respect to an ordered phase (II) below 250 K, but in...

In the last five years, we have carried out a comprehensive study of the family of REMn2O5 multiferroics by neutron and X-ray magnetic scattering, providing details about the...

We propose to use NR to study the structural features of the model wheat wax films formulated from the known main components of long chain primary alcohols and an ester. By...

There is considerable effort being put into the modelling of the outer layer of skin, the stratum corneum, because of impending EU restrictions on the use of animal skin for...

The formation of silk fibres in both spiders and silkworms is characterized by a conversion of short range ordered structures in solution into long range ordered beta-sheet rich...

Quantum phase transitions (QPT) continue to attract the attention of experimentalists and theorists alike. Experiments on quantum magnets have been crucial to understand their...

Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be...

Noncentrosymmetric superconductors have been identified as good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...
