Bimetallic alloy catalysts with optimized metal ratio usually exhibit a superior catalytic hydrogenation activity and selectivity compared to individual mono-metallic catalysts,...

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

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...

Recent theories and experiments on two-dimensional triangular lattice antiferromagnet show that the spin dynamics of these system exhibit the rare phenomena due to high-order...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

We have devoted much efforts to investigating the doping evolution of the magnetic excitations in electron doped BaFe2-xNixAs2 (x=0-0.6). Spin excitations for x=0-0.6 have been...

The solution of the Anderson lattice model (ALM) leads to two renormalized bands near EF with an energy gap due to hybridization between the 4f- and conduction electrons. The...

Finely divided, supported palladium particles are used as catalysts in many technical processes. However, there is still considerable potential to improve catalyst performance...

The proposal requests time to measure the magnetic fluctuations in a 2 dimensional ferromagnet where the dimensionality is set by weak van der Waals forces. We have previously...

Heavy fermion compounds with a small energy gap opening in the strongly hybridised 4f-band at EF are currently under intensive investigations. Recently some of us have...

Cobalt based catalysts are widely used within industry for Fischer-Tropsch synthesis (FTS) in the production of sulphur free diesel. Despite the wide application of cobalt...

The frustrated magnetism of pyrochlores makes them candidates for applications in magnetic cooling and scientific instrumentation, and the proposal that they can be used to...

Hexagonal iridate Na2IrO3 has recently been proposed as a candidate material to exhibit strong spin-orbit coupling effects which may stabilize a Mott insulating state with...

the correlation degree in 122 iron pnictides mainly depends on the electronoccupancy of each orbital and that by doping electrons the correlation decreases monotonically. This...

The rare-earth frustrated magnets with dipole-octupole doublet trigger intense research interests due to their exotic quantum phases including spin fragmentation. The newly...

KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A...

The reaction of methanol to form hydrocarbons over zeolite catalysts is an important option for conversion of natural gas or coal to liquid fuels. We have shown previously...
