Temperature-regulated guest admission and release in microporous materials

Li, Gang ; Shang, Jin ; Gu, Qinfen ; ... - Nature Communications

While it has long been known that some highly adsorbing microporous materials suddenly become inaccessible to guest molecules below certain temperatures, previous attempts to explain this phenomenon have failed. Here we show that this anomalous sorption behaviour is a temperature-regulated guest admission process, where the pore-keeping group’s thermal fluctuations are influenced by interactions with guest molecules. A physical model is presented to explain the atomic-level chemistry and structure of these thermally regulated micropores, which is crucial to systematic engineering of new functional materials such as tunable molecular sieves, gated membranes and controlled-release nanocontainers. The model was validated experimentally with Hmore »« less

Unexpectedly stable clathrate hydrates formed from microporous vapor-deposited amorphous solid water at low 'external' guest pressures and their astrophysical implications

Hallbrucker, A. ; Mayer, E. - Icarus (International Journal of the Solar System); (USA)

The formation of O{sub 2}-clathrate hydrate from O{sub 2} trapped in micropores of vapor-deposited amorphous water ice during heating and sintering at temperatures up to 120 K and 'external' O{sub 2} pressures 10, 100, 200, and 1000 mbar is reported. X-ray diffraction studies show that the clathrate hydrate forms at 170-210 K, even at the lowest O{sub 2} pressure (10 mbar) and does not decompose until the temperature reaches 240-250 K (significantly higher than predicted previously). The importance of the presence and sintering properties of micropores in amorphous water ice for theoretical models of clathrate hydrate formation in the solarmore » system is indicated. 44 refs.« less

Nuclear materials safeguards -- The price of admission for Russian-US nuclear collaborations

Hecker, S.S. ; Mullen, M.F. ; Toevs, J.W. - Transactions of the American Nuclear Society

In the summer of 1994, the US Department of Energy (DOE) initiated a joint program with Russia and the other states of the FSU (former Soviet Union) to help them upgrade their nuclear materials safeguards. The so-called materials protection, control, and accounting (MPC and A) program was based on a novel laboratory-to-laboratory approach, taking advantage of the trust that DOE laboratory scientists and engineers had developed with their Russian nuclear laboratory counterparts in joint scientific collaborations dating back to 1992. This approach proved very successful in tackling the extremely sensitive issue of how the United States could help Russia modernizemore »« less
