WebSep 15, 2000 · 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 parameters of the encaged methane molecules have been obtained. The parameters of the host lattice differ … WebJournal of Chemical Crystallography is an international and interdisciplinary publication dedicated to the rapid dissemination of research results in the general areas of …

MicroED Structure of a Protoglobin Reactive Carbene Intermediate

WebCrystallisation is a process that occurs when a set of molecules comes together to form a condensed array with regular repeating interactions. A fundamental understanding of these interactions is therefore crucial in the analysis, evaluation and prediction of crystal forms. WebAbstract. The vast majority of materials have a positive coefficient of thermal expansion and their volume increases on heating. There has been considerable recent interest in materials which display the unusual property of contracting in volume on heating; i.e. those with a negative coefficient of thermal expansion. This Perspective gives an overview of some of … marshall field furniture store
