Original Source: Polarity, Viscosity, and Ionic Conductivity of Liquid Mixtures Containing C(4)C(1)imNtf(2) and a Molecular Component.
In this study, we have focused on binary mixtures composed of 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)-imide, [C(4)C(1)im][Ntf(2)], and a selection of six molecular components (acetonitrile, dichloromethane, methanol, 1-butanol, t-butanol, and water) varying in polarity, size, and isomerism. Two Kamlet-Taft parameters, the polarizability π* and the hydrogen bond acceptor β coefficient were determined by spectroscopic measurements. In most cases, the solvent power (dipolarity/polarizabilit...

Systematic genetic interaction screens uncover cell polarity regulators and functional redundancy
Cell polarity is important for the function of many animal cells, and several aspects of its establishment are conserved across species, from worm to human. Ahringer and colleagues have performed larg...
Principles of PAR polarity in Caenorhabditis elegans embryos
The distribution of partitioning defective (PAR) proteins into two domains on the membrane is a hallmark of cell polarity. Domain boundaries are set by mechanical, biochemical and biophysical signals,...
Cell polarity: Translating polar cues
RAP2A provides a link between apical polarity cues and cytoskeletal regulators during brush border formation.
Unlocking fuel cell conductivity
(Springer) Yttria stabilized zirconia, also known as YSZ, is a material of great interest because of its relatively high oxygen-ion based conductivity. It finds applications in electrochemical devices...

Effects of interfacial modifications on electrical properties of laminar composite dielectrics.
The reported work highlights that both polarizibility and quasi-DC conductivity, the two most important parameters for high energy density materials, can be influenced by the surface polarity of an ox...
Limits of proton conductivity.
Parasitic current seems to be the cause for the "highest proton conductivity" of a material reported to date. Kreuer and Wohlfarth verify this hypothesis by measuring the conductivity of the same mate...
The axon initial segment and the maintenance of neuronal polarity.
Ion channel clustering at the axon initial segment (AIS) and nodes of Ranvier has been suggested to be a key evolutionary innovation that enabled the development of the complex vertebrate nervous syst...
