  • B-N compounds for chemical Hydrogen storage
    Chemical Society Reviews, 2009
    Co-Authors: Charles W. Hamilton, R. Tom Baker, Anne Staubitz, Ian Manners
    Abstract:

    Hydrogen storage for transportation applications requires high volumetric and gravimetric storage capacity. B-N compounds are well suited as storage materials due to their light weight and propensity for bearing multiple protic (N-H) and hydridic (B-H) Hydrogens. This critical review briefly covers the various methods of Hydrogen storage, and then concentrates on chemical Hydrogen storage using B-N compounds. The simplest B-N compound, ammonia borane (H3NBH3), which has a potential 19.6 wt% Hydrogen storage capacity, will be emphasised (127 references).

  • Vapor-liquid interfacial properties of mutually saturated water/1-butanol solutions.
    Journal of the American Chemical Society, 2002
    Co-Authors: Bin Chen, J. Ilja Siepmann, Michael L. Klein
    Abstract:

    Adsorption and ordering at the vapor−liquid interfaces of mutually saturated water/1-butanol solutions at a temperature of 298.15 K were investigated using configurational-bias Monte Carlo simulations in the Gibbs ensemble and compared to the surface properties of neat water and 1-butanol liquids. A dense 1-butanol monolayer is observed at the surface of the water-rich phase, which results in a substantial decrease of its surface tension. In contrast, there is no enrichment of water molecules at the surface of the butanol-rich phase, and its surface tension is not significantly changed. Analysis of the interfacial structures reveals that these systems exhibit orientational ordering and composition heterogeneity. Analysis of the Hydrogen-bonding distributions suggests that the formation of the 1-butanol monolayer is driven by an excellent match between water and the primary alcohol; that is, additional Hydrogen bonds are formed between the excess free Hydrogens of surface water and the excess Hydrogen-bond…

  • swelling induced surface instability of a Hydrogen bonded lbl film and its self healing
    Polymer, 2014
    Co-Authors: Chong Li, Ying Guan, Yongjun Zhang
    Abstract:

    Thin hydrogel films attached to a rigid substrate can only swell along the direction perpendicular to the substrate, which generates compressive stress within the gel. When the stress is sufficiently large, the free surface of the gel will locally buckle and fold against itself to form various wrinkling patterns. Here we show that Hydrogen-bonded layer-by-layer (LBL) films of poly(vinyl pyrrolidone) (PVPON) and poly(acrylic acid) (PAA) also swell in ethanol/water mixtures. Like ordinary hydrogel films attached to a substrate, the LBL films also undergo mechanical instability when their swelling degree is large enough. By adjusting the composition and pH of the ethanol/water mixture, the swelling degree of the film can be adjusted, which further decides whether the mechanical instability occurs or not. Like ordinary hydrogel films, the surface wrinkling of the PVPON/PAA films occurs via a nucleationgrowth process. Unlike ordinary hydrogels, the critical swelling degree for the onset of wrinkling for PVPON/PAA films increases with increasing film thickness. More importantly, the wrinkling patterns can be healed automatically, because the transient network of PVPON/PAA films allows for the relief of compressive stress via its rearrangement. The phenomenon observed here may provide a possible way to erase the undesired wrinkling patterns on constrained hydrogel films.
