Recent advances in thermodiffusion (Soret effect) in binary and higher multicomponent liquid mixtures are reviewed. The mixtures studied include the hydrocarbon, associating, molten metal and semiconductor, polymer, and DNA mixtures. The emphasis is placed on the theoretical works, particularly models based on the nonequilibrium thermodynamics, although other approaches such as the statistical,...

The hydroisomerization of pure n-pentane over H-mordenite supported Pt-catalyst was investigated in a fixed bed reactor by changing reaction parameters such as temperature, pressure, and WHSV, as well as the H2/HC ratio. The maximum yield of isopentane over Pt/mordenite catalyst was achieved at 220 °C and a relatively low reaction pressure. To address the effect of feed composition on the catal...

this research paper presents the use of wasteful supplementary cementitious materials like fly ash and silica fume to conserve the cement used in concrete. the cement industry is one of the major producers of greenhouse gases and an energy user. in this study, portland cement was used as a basic cementitious material. fly ash and silica fume were used as the cement replacements by weight. the r...

We present an efficient and robust method based on Monte Carlo simulations for predicting crystal structures at finite temperature. We apply this method, which is surprisingly easy to implement, to a variety of systems, demonstrating its effectiveness for hard, attractive, and anisotropic interactions, binary mixtures, semi-long-range soft interactions, and truly long-range interactions where t...

Eleven iron(II) 1D coordination polymers with the general formula [FeLeq(Lax)]· solvent were synthesised and characterised, where Leq = {diethyl (E,E)-2,2′-[1,2-phenylbis(iminomethylidyne)]bis[3-oxobutanoate] (2-)-N,N′,O,O′} (L1) and {3,3′-[1,2-phenylbis(iminomethylidyne)]bis[pentane-2,4-dione] (2-)-N,N′,O,O′} (L2); Lax = 4,4′-bipyridine (bipy), 1,2-bis(4-pyridyl)ethane (bpea) and 1,3-bis(4-pyr...
