We propose to study a model phyllosilicate catalyst that, upon brief thermal treatment, releases OH groups from its surface to generate pockets of coordinatively unsaturated...

Our recent express measurments on protonated and deuterated 7,7,8,8-tetracyanoquinodimethane (TCNQ) have highlighted some interesting differences between the two. We seek to...

To determine the temperature dependence of the structures of new mixed and ionic conducting materials in the n = 2 ruddlesden-popper,mellilite and pyrochlore systems.

Recent theoretical work has identified that oxygen octahedral rotations (OORs) in layered perovskites such as Ruddlesden-Popper (RP) phases can generate noncentrosymmetry...

There is an increasing interest in the application of gallium oxide as a catalyst support material, with particular interest in its use in new methanol steam reforming...

Proton conducting BaTi1-xScxO3Hx (BTS) perovskites are promising materials for proton conducting fuel cells in the intermediate temperature regime (200-600 °C). Compared to...

CaMnO3-based perovskite oxides show promise as solid oxygen carriers for use in chemical looping. Partial substitution with small amounts of Sr increases both the capacity and...

Apatites are currently of major interest in a number of fields: biomaterials, solid oxide fuel cells, catalysis, environmental remediation to name a few. Hydroxyapatite -...

We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial...

Apatites are a large group of chemically and structurally flexible functional materials with important applications as solid electrolytes. The majority of known apatite...

Soft self-assembled structures have been extensively used as drug nanocarriers. Their building blocks, naturally occurring and synthetic amphiphiles (lipids or block...

Understanding the magnetic exchange coupling and fundamental Hamiltonian of the parent compound of FeAs-based superconductors is extremely important, because such information...

The concept of an aristotype, or equivalently, the basic structure, that represents the highest symmetry crystal structure that can be attained, either experimentally, or...

Tetragonal tungsten bronzes have three types of channels for ions with the smallest unusually occupied with Li in potassium lithium tantalate (KLT). This creates complexity...

Coating two surfaces with polymer brushes has been shown on many occasions to reduce friction by orders of magnitude. These ultra-low frictions are believed to stem from be the...

Much effort has been devoted to the research of new NTE materials and the understanding of the mechanism driving this phenomenon. As part of our ERC grant on ‘orbital...

The vibrational spectrum of C70 has been investigated by many techniques since it became available in significcant quantities. Previous INS spectra were recorded with small...

The gram-negative bacterial membrane is of extreme medical importance. Two of its major components are lipopolysaccharides (LPS's) and integral membrane proteins. Porins are...

Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...

One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or...
