At a nanometre scale, the behaviour of biological fluids is largely governed by interfacial physical chemistry. This may manifest as slowed or anomalous diffusion. Here we describe how measures ...

In this interview, AZoM speaks to Dr Larry Spino about Viscosity analysis, what is constant pressure viscometry and its benefits and what PAC L.P. offers to fulfil viscosity analysis needs. Viscosity ...

It is important to understand that there is no simple relationship between viscosity and particle size that covers all types of liquids. Liquid viscosity is caused by forces between its particles, ...

Near-optimization is as sensible and important as optimization for both theory and applications. This paper concerns dynamic near-optimization, or near-optimal controls, for systems governed by ...

THE abnormally high heat conductivity of helium II below the λ-point, as first observed by Keesom, suggested to me the possibility of an explanation in terms of convection currents. This explanation ...
