On the dependence of surface tension of liquids on the curvature of the liquid-vapor interface

Article Abstract:

Conventional methods for measuring pore-size distribution (PSD) based on capillary condensation (CC) and mercury intrusion porosimetry (MIP) are very sensitive to the numerical values of surface tension of the corresponding liquid phase. Experimental studies suggest no significant dependence of sigma on the curvature of the interface at the range of subnanometer radii.

Observation of the effect of wetting efficiency on a flow of liquids impinging on solid substrates by fluorescence depolarization

Article Abstract:

An evaluation of the polarised laser-induced fluorescence (PLF-FI) efficiency for the study of the dynamic interfacial tention of liquid thin films flowing without boundaries on solid substrates is presented. Hierarchic cluster analysis (HCS) showed that, as adhesion decreased, similarity among the polarization maps increased.

Textural changes during topochemical decomposition of nanocrystalline Mg(OH)2 to MgO

Article Abstract:

Transformation of nanocrystalline Mg(OH)2 to MgO under dynamic vacuum in a temperature range of 570-770 K is studied by TGA-GCMS, FTIR, HREM, XRD, helium pycnometry, and nitrogen adsorption at 77 K. A new phenomenon of decrease of the interlayer distance in MgO crystallites with increase of the nanoparticle size was observed.
