The accurate determination of the ambient dose equivalent in the mixed neutron-photon fields encountered around high-energy particle accelerators still represents a challenging task. The main complexity arises from the extreme variability of the neutron en ...
Inelastic electron scattering is applied to investigate the impact of potassium intercalation on the charge-carrier plasmon energy and dispersion in the charge- density wave (CDW) bearing compound 2H-TaSe2. We observe an unususal doping dependence of the p ...
The hydrogen storage properties of Fe2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) and an oxidized analog, Fe2(O2)(dobdc), have been examd. using several complementary techniques, including low-pressure gas adsorption, neutron powder diffractio ...
An incommensurate elliptical helical magnetic structure in the frustrated coupled-spin-chain system FeTe2O5Br is surprisingly found to persist down to 53(3) mK (T/T-N similar to 1/200), according to neutron scattering and muon spin relaxation. In this stat ...
We have investigated the influence of potassium intercalation on the formation of the charge-density wave (CDW) instability in 2H-TaSe2 by means of electron energy-loss spectroscopy and density functional theory. Our observations are consistent with a fill ...
We have investigated the magnetic structure in a polycrystalline sample of the B20-type MnGe by means of small-angle neutron scattering. On the projected diffraction plane normal to the incoming neutron beam, a Debye-ring-like pattern appears due to the ra ...
This study was conducted to synthesize thermally-robust metal-org. frameworks with high internal surface areas and a high concn. of open metal coordination sites for hydrogen storage. A no. of strategies were used for generating open metal coordination sit ...
In the field of quantum magnetism, neutron scattering techniques allows probing of the magnetic properties of many materials, as the neutrons carry spin. Interesting materials are for example the parent compound of a high temperature superconductor La2CuO4 ...
We present a comparison between sum frequency scattering (SFS) and reflection mode sum frequency generation (R-SFG). We have used scattering theory to describe both scattering experiments as well as reflection mode experiments. The interfacial vibrational ...
The motion of the excess proton is understood as a process involving interconversion between two limiting states, namely, the Eigen and Zundel cations. Nuclear quantum effects (NQE) and the organization of the surrounding solvent play a significant role in ...
