Journal ArticleDOI
A partially interpenetrated metal-organic framework for selective hysteretic sorption of carbon dioxide
Sihai Yang,Xiang Lin,William Lewis,Mikhail Suyetin,Elena Bichoutskaia,Julia E. Parker,Chiu C. Tang,David R. Allan,Pierre J. Rizkallah,Peter Hubberstey,Neil R. Champness,K. Mark Thomas,Alexander J. Blake,Martin Schröder +13 more
TL;DR: Temperature-dependent adsorption/desorption hysteresis in desolvated NOTT-202a that responds selectively to CO(2) is reported, and stepwise filling of pores generated within the observed partially interpenetrated structure has been modelled by grand canonical Monte Carlo simulations.
Journal ArticleDOI
The Use of Quartz as an Internal Pressure Standard in High-Pressure Crystallography
TL;DR: The use of oriented quartz single crystals is proposed as an improved internal pressure standard for high-pressure single-crystal diffraction experiments in diamond-anvil cells in this article.
Journal ArticleDOI
Stable methane hydrate above 2 GPa and the source of Titan's atmospheric methane
John Loveday,R. J. Nelmes,Malcolm Guthrie,S. A. Belmonte,David R. Allan,Dennis D. Klug,John S. Tse,Y. P. Handa +7 more
TL;DR: In this article, the authors report neutron and synchrotron X-ray diffraction studies that determine the thermodynamic behavior of methane hydrate at pressures up to 10 GPa.
Journal ArticleDOI
Metal−Organic Polyhedral Frameworks: High H2 Adsorption Capacities and Neutron Powder Diffraction Studies
Yong Yan,Irvin Telepeni,Sihai Yang,Xiang Lin,Winfried Kockelmann,Dailly Anne M,Alexander J. Blake,William Lewis,Gavin S. Walker,David R. Allan,Sarah A. Barnett,Neil R. Champness,Martin Schröder +12 more
TL;DR: Neutron powder diffraction experiments on D(2)-loaded NOTT-112 reveal that the axial sites of exposed Cu(II) ions in the smallest cuboctahedral cages are the first, strongest binding sites for D( 2) leading to an overall discrimination between the two types of exposure sites at the paddlewheel nodes.
Journal ArticleDOI
Effect of high pressure on the crystal structures of polymorphs of glycine
Alice Dawson,David R. Allan,S. A. Belmonte,Stewart J. Clark,William I. F. David,Pamela A. McGregor,Simon Parsons,Colin R. Pulham,Lindsay Sawyer +8 more
TL;DR: The effect of high pressure on the crystal structures of α-, β-, and γ-glycine has been investigated in this article, where a new polymorph, δ-Glycine, was obtained from β glycine.
