Effective Volumetric Factor for Inhomogeneous Temperature in Volumetric Measurements of Gas Absorption and Desorption

Accounting of effective volumetric factor for the measurement at inhomogeneous temperature allows to the simplify the measurement process avoiding a pre-calibration with a noble gas. The volumetric correction in form of the volumetric factor is calculated analytically by modeling of the temperature profile in the volumetric apparatus, and provides a quite agreement with the measured results. The calculation can be applied for each volumetric measurement with an inhomogeneous temperature distribution

Giant water clusters: where are they from?

A new mechanism for the formation and destruction of giant water clusters described in the literature is proposed. We have earlier suggested that the clusters are associates of liquid crystal spheres (LCS), each of which is formed around a seed particle, a micro-crystal of sodium chloride. In this paper, we show that the ingress of LCS in water from the surrounding air is highly likely. When a certain threshold of the ionic strength of a solution is exceeded (for example, in the process of evaporation of a portion of water), the LCS begin to melt, passing into free water, and the salt crystals dissolve, ensuring re-growth of larger crystals as a precipitate on the substrate. A schematic diagram of the dynamics of phase transitions in water containing LCS during evaporation is proposed.Comment: 9 pages, 9 figures, 29 reference
