The performance of functional composites can rely critically on the arrangement of secondary phases; for example, patterned networks of conductive particles can impart anisotropic thermal, electric or ionic conductivity while preserving flexibility i

The phenomenon of electrical conductivity maxima of molten salts versus temperature during orthobaric (closed-vessel) conditions is further examined. First, we summarize results from density-functional-based molecular dynamics simulations of molten S

The nature of the ions present in mixtures of trialkylamines (B) with carboxylic acids (HA) is discussed. New ab initio molecular dynamics (AIMD) simulations of mixtures of triethylamine (TEA) with acids here reveal the same cation type, the large co

Explanations are provided for the first time for the historically known locations of electrical conductivity maxima versus mixing ratio (mole fraction of acid, xA) in mixtures of (i) acetic acid with water and (ii) acetic acid with pyridine. To resol

We report significant and reproducible growth acceleration of human progenitor cells when exposed to rotational flow when compared with stationary conditions. Nonenriched CD34+ umbilical cord derived human hematopoietic progenitor cells were cultured
