“…The membranes were not sputtered to keep the sample's surface morphology unchanged and were observed using low accelerating voltage of 1 kV and a low electron beam current of 100 pA to prevent surface charging and modification during SEM imaging. The membrane was submerged in liquid nitrogen for about one minute and was fractured perpendicular to the surface in the liquid nitrogen after reaching the Leidenfrost point [54]. After crushing, the sample was removed from liquid nitrogen and dried in air for 5 min.…”

Novel mixed matrix dense and supported membranes based on biopolymer sodium alginate (SA) modified by fullerenol were developed. Two kinds of SA–fullerenol membranes were investigated: untreated and cross-linked by immersing the dry membranes in 1.25 wt % calcium chloride (CaCl2) in water for 10 min. The structural and physicochemical characteristics features of the SA–fullerenol composite were investigated by Fourier-transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopic methods, scanning electron (SEM) and atomic force (AFM) microscopies, thermogravimetric analysis (TGA), and swelling experiments. Transport properties were evaluated in pervaporation dehydration of isopropanol in a wide concentration range. It was found that the developed supported cross-linked SA-5/PANCaCl2 membrane (modified by 5 wt % fullerenol) possessed the best transport properties (the highest permeation fluxes 0.64–2.9 kg/(m2 h) and separation factors 26–73,326) for the pervaporation separation of the water–isopropanol mixture in the wide concentration range (12–90 wt % water) at 22 °C and is suitable for the promising application in industry.

“…This would be a prominent step towards the numerical simulation of pool boiling from tube bundles flooded in a bath of boiling fluid. Furthermore the conclusions of extensive CFD simulations of Gu et al [19] were applied to accurate closures in the RPI boiling model. Finally, the effect of working fluid, saturation temperature and tube orientation have been investigated on the pool boiling heat transfer for the first time.…”

Abstract. This article deals with a problem of evaporation numerical modeling in cryogenic systems of constant volume. Particularly, a method of nitrogen evaporation modeling in cryogenic fueling tank was considered. Userdefined functions of nitrogen thermodynamic properties in temperature range of 70...400 K and pressure range of 0.1...30 MPa. The result of this research is calculation algorithm which allows to model processes of phase change in cryogenic systems with constant volume. A comparison obtained between results of numerical modeling with experimental and analytical data is presented. Deviation of results from experimental data is 5-10%.
