Competition between Intra- and Intermolecular Association of Chain Molecules with Water-like Solvent

22.05.2015 | Deepti Ballal; Walter G. Chapman, Journal of Physical Chemistry B, 2015

Fluid properties and phase behavior of systems such as glycol ethers, carboxylic acids, and proteins are affected by the competition between intra- and intermolecular hydrogen bonding. Here we study this competition by extending Wertheim’s first-order thermodynamic perturbation theory to include ...

Promising gaseous and electrochemical hydrogen storage properties of porous Mg–Pd films under mild conditions

21.05.2015 | Gongbiao Xin; Huiping Yuan; Lijun Jiang; Shumao Wang; Xiaopeng Liu; Xingguo Li, Physical Chemistry Chemical Physics, 2015

In this paper, the gaseous and electrochemical hydrogen storage properties of 200 nm Mg–Pd thin films with different morphologies have been investigated. The results show that Mg–Pd films become porous with the increase of substrate temperature. Porous Mg–Pd films exhibit superior gaseous and ...

The Hydric Effect in Inorganic Nanomaterials for Nanoelectronics and Energy Applications

20.05.2015 | Xu Sun, Yuqiao Guo, Changzheng Wu, Yi Xie, Advanced Materials, 2015

Protons, as one of the world's smallest ions, are able to trigger the charge effect without obvious lattice expansion inside inorganic materials, offering a unique and important test‐bed for controlling their diverse functionalities. Arising from the high chemical reactivity of hydrogen (easily ...

An Infrared Spectroscopic and Theoretical Study on (CH3)3N-H+-(H2O)n, n = 1 – 22: Highly Polarized Hydrogen Bond Networks of Hydrated Clusters

20.05.2015 | Ryunosuke Shishido; Yin- Chen Li; Chen-Wei Tsai; Dan Bing; Asuka Fuji; Jer-Lai Kuo, Physical Chemistry Chemical Physics, 2015

Infrared spectra of protonated trimethylamine (TMA) - water clusters, (CH3)3N-H+-(H2O)n (n = 1 – 22) were measured in the OH stretching vibrational region by size-selective photodissociation spectroscopy. Density functional theory calculations of stable structures were performed, and temperature ...
