Inkjet printing of alternate layers of anionic and cationic polyelectrolytes allows organized gels to form with structures similar to those made by layer--by-layer dipping methods but very much faster. Structures of gels formed using slow and fast inkjet printing systems are compared using elemental analysis, swelling and diffusion kinetics as characterization methods. After printing and washing, most sodium or chloride counter-ions are last from the gel, leave only the polymer complex. The swelling properties of the printed and washed gel depend on the deposition rate and on the ratio of the two polymers as originally printed. The synthetic polyelectrolytes reported …

Structures of gels formed using slow and fast inkjet printing systems are compared using elemental analysis, swelling and diffusion kinetics as characterization methods. After printing and washing, most sodium or chloride counter-ions are lost from the gel, leaving only the polymer complex.

The Vibrational Spectra Of Protonated Water Clusters: A Benchmark For Self-Consistent-Charge Density-Functional Tight Binding, Haibo Yu, Qiang Cui

Proton transfers are involved in many chemical processes in solution and in biological systems. Although water molecules have been known to transiently facilitate proton transfers, the possibility that water molecules may serve as the “storage site” for proton in biological systems has only been raised in recent years. To characterize the structural and possibly the dynamic nature of these protonated water clusters, it is important to use effective computational techniques to properly interpret experimental spectroscopic measurements of condensed phase systems. Bearing this goal in mind, we systematically benchmark the self-consistent-charge density-functional tight-binding �SCC-DFTB� method for the description of vibrational spectra …
Reconciling Self: Gay Men And Lesbians Using Domestic Materiality For Identity Management, Andrew W. Gorman-Murray
Reconciling Self: Gay Men And Lesbians Using Domestic Materiality For Identity Management, Andrew W. Gorman-Murray

This paper contributes to research on gay/lesbian experiences, meanings and uses of domestic environments by considering the role of domestic materiality in gay/lesbian identity management. Prior work shows that accumulating and arranging meaningful possessions in domestic space underwrites identity work. Drawing on in-depth interviews with gay/lesbian Australians, I apply this contention to gay/lesbian homemaking practices. In particular, conceptualising identity as fractured, I argue that maintaining domestic materiality reconciles diverse dimensions of multi-faceted selves. Different possessions embody different facets of self – sexuality, familial connections, cultural heritage, spiritual beliefs, inter alia. Juxtaposing these objects at home brings together the diverse fragments …

The charge-on-spring method is used to develop a rigid, three-site, polarizable water model, a noniterative and a self-consistent version. In this method, the polarizability is taken into account by a variable separation of charges on selected polarizable centers. One of the pair of polarization charges resides on a polarizable center, while the other one is treated as an additional particle attached to the polarizable center by a parabolic restraint potential. The separation is calculated in response to the instantaneous electric field. We parametrized two models which are based on noniterative and self-consistent versions of the method, respectively. We computed several …
