The thermal conductivity of a gas hydrate is much lower than that of ice and more intriguingly, in spite of the crystalline structure, the temperature profile resembles an amorphous solid. Here we present results from neutron incoherent inelastic sca

We present the results of a high-resolution neutron diffraction experiment with a fully deuterated methane hydrate type I at temperatures of 2, 100, and 150 K. Precise crystallographic parameters of the ice-like D 2 O lattice and the thermal paramete

In this work we present the results from studies on novel poly(arylene ether ketone)s, including gas permeability, wide-angle x-ray diffraction (WAXD), and dynamic mechanical analysis (DMA). Poly(arylene ether ketone)s containing 2,2'-and 3,3'-dibenz

The thermal properties of 2,3-dimethyl-2,3-dinitrobutane (DMNB), a detection agent for explosives, have been determined by DSC measurements. Additionally, the results of an NMR study are compared with conclusions arrived at in the literature with reg

The vibrational densities of states in the lattice translation region below 130 cm −1 (3 THz) for structure I xenon hydrate and structure II krypton hydrate have been determined from incoherent inelastic neutron scattering experiments. The main fea

Phase transitions, phase structures, and guest motions in the clathrasil Dodecasil-3C were studied by means of calorimetry, solid-state NMR, dielectric relaxation, and synchrotron powder diffraction. In contrast to the behavior of the empty clathrasi

This paper reviews four aspects of hydrogen bonding in both the vapour and the solid phases of water. 1. The first aspect is the dimerization of H 2 O and D 2 O molecules in the vapour phase, as measured by their second virial coefficients. The diffe

Thermal analysis of solid C 60 (buckminsterfullerene) has been conducted from 150 to 1000 K with a differential scanning calorimeter. The onsets of two endothermic transitions are observed at 221 and 252 K. Low temperature X-ray powder diffraction ex

Ice I transforms to a high‐density amorphous phase when pressed to 10 kbar at 77 K. Similar transformations in structure I and structure II clathrate hydrates have been studied by pressing samples in a piston‐cylinder apparatus and by molecular d
