Nickel titanium (NiTi) foams were made by combustion synthesis of powders with the help of ZrH2 as foaming agent and TiB2 as endothermic agent. In this paper, we investigated the effect of elemental powder size on the foaming. The powder size of Ni and Ti affected the ignition temperature of the combustion reaction, cell morphology and microstructure of the foams. The cell morphology of the foa...

The present work investigates the equilibrium adsorption of Chrysene on multi-walled carbon nanotubes at 293, 303 and 313°K, and determines the equilibrium adsorption isotherms and thermodynamic parameters (ΔG, ΔH and ΔS). The values of ΔH and ΔG suggested that the adsorption of Chrysene onto MWCNTs was endothermic and nonspontaneous.The experimental data were analyzed using Langmuir, Freundlic...

The phase transition of dipalmitoyl lecithin, measured by thermal analysis, was eliminated by the plant sterol, sitosterol, and by the derivatives steryl glucoside and acylated steryl glucoside, which were isolated from soybean lipids.When digitonin was added to dipalmitoyl lecithin-sterol mixtures, in amounts equimolar to sterol, the phase transition of the phospholipid was revealed presumably...

The kinetics, energetics, and structure of Cyclolinopeptide A binding with Human Serum Albumin were investigated with surface plasmon resonance and circular dichroism. The complex is formed through slow recognition kinetics that is temperature sensitive in the range of 20°C-37°C. The overall reaction was observed to be endothermic (ΔH = 204 kJ mol(-1)) and entropy driven (ΔS = 746 J mol(-1)K(-1...

      Simulation of metallurgical processes has been the subject of intense research due to the reduced number of experiments required for controlling the process as well as time and energy savings it allows. In gas carburizing of steel parts, the amount of carbon at the surface of carburized parts is the most important specification of the process in terms of achieving the desired metallurgica...

Abstract This work combines hydrophobic and heat-absorbing materials to solve the problem of water frost resistance in industrial domestic scenarios harsh environments. Here, highly fast endothermic (HHFE) surfaces were prepared by applying candle soot (nanocarbon) as template, slides carrier nano-TiO2 a backbone connecting layer. The resulting HHFE surface exhibited coral-like porous structure...
