Nanofriction on Sodium Polystyrene Sulfonate Brushes in Water [PDF]
arXiv, 2014 We investigated the frictional properties of sodium polystyrene sulfonate (NaPSS) brushes in water by frictional force microscopy (FFM). Polyelectrolyte brushes were prepared on silicon wafers by the grafting-to method. The brushes considerably reduce the frictional force and coefficient of kinetic friction compared to hydrodynamic lubrication on a ...

Predicted field-induced hexatic structure in an ionomer membrane [PDF]
, 2008 Coarse-grained molecular-dynamics simulations were used to study the morphological changes induced in a Nafion$^{\tiny \textregistered}$-like ionomer by the imposition of a strong electric field. We observe the formation of novel structures aligned along the direction of the applied field.

Combating the Stigmatization of Leprosy: How the first decade of The Star’s publication made the case for romantic relationships and the preservation of domestic life in the Carville Leprosarium [PDF]
, 2013 The stigmatization of leprosy has long been acknowledged as one of the primary obstacles to not only effectively treating leprous patients on a physical level, but also achieving their integration and acceptance into society.

Highly-functionalised difluorinated cyclohexane polyols via the Diels–Alder reaction : regiochemical control via the phenylsulfonyl group [PDF]
, 2005 A difluorinated dienophile underwent cycloaddition reactions with a range of furans to afford cycloadducts whichcould be processed regio- and stereoselectively via episulfonium ions, generated by the reaction between their alkenyl groups and ...

New Synthetic Approaches to Alk-1-enyl Sulfones and Sulfoxides [PDF]
, 2007 This thesis is devoted to the finding of new synthetic approaches to alk-1-enyl sulfones and sulfoxides. In particular, uncomplexed organoaluminum reagents reacted with aluminium sulfinates to afford alkenyl sulfoxides in good yields (72-75%).

Radical Fluoroalkylation Reactions [PDF]
, 2018 Recent protocols and reactions for catalytic radical perfluoroalkylations will be described. The production of perfluoroalkyl radicals (RF = CnF2n+1, n ≥ 2), which effect both addition and substitution reactions on organic substrates, can be realized ...

Simulation Study of Ion Diffusion in Charged Nanopores with Anchored Terminal Groups [PDF]
arXiv, 2017 We present coarse-grained simulation results for enhanced ion diffusion in a charged nanopore grafted with ionomer sidechains. The pore surface is hydrophobic and its diameter is varied from 2.0 nm to 3.7 nm. The sidechains have from 2 to 16 monomers (united atom units) and contain sulfonate terminal groups.
