Fast crystalline ice formation at extremely low temperature through water/neon matrix sublimation

20.06.2017 | Tetsuya Hama; Shinnosuke Ishizuka; Tomoya Yamazaki; Yuki Kimura; Akira Kouchi; Naoki Watanabe; Toshiki Sugimoto; Val ..., Physical Chemistry Chemical Physics, 2017

Crystalline ice formation requires water molecules to be sufficiently mobile to find and settle in the thermodynamically most stable site. Upon cooling, however, diffusion and rearrangement become increasingly kinetically difficult. Water ice grown by the condensation of water vapor in laboratory ...

A Cd mixed-ligand MOF showing ligand-disorder induced breathing behaviour at high temperature and stepwise, selective carbon dioxide adsorption at low temperature

20.06.2017 | Tayyibah Tahier; Clive L. Oliver, CrystEngComm, 2017

A mixed-ligand MOF [Cd(bpe)1.5(nbdc)]n·nDMF0.84 (1) has been synthesized where bpe = 1,2-bis(4-pyridyl)ethane, nbdc = 5-nitro-1,3-benzenedicarboxylate and DMF = N,N′-dimethylformamide. Single crystal X-ray diffraction studies reveal that the structure consists of 2-periodic, 3D nets which exhibit ...
