This study presents thermodynamic approaches for selecting a hydrate former suitable for water treatment. Here, carbon dioxide (CO2) and 1,1,1,2-tetrafluoroethane (HFC-134a) were investigated as hydrate formers. Simulated studies of the hydrate formation by four formers were conducted at different NaCl concentrations (0.00, 1.75, and 3.50 wt%) to predict the phase-equilibrium conditions.

In this study, we synthesized hydroxyapatite (HA) on polyvinyl alcohol/TiO2 (PVA/TiO2) in which TiO2 was prepared by the sol-gel method. HA was formed by immersing the membrane in the simulated body fluid (SBF) solution. We improved the mechanical strength of the membranes by adding glutaraldehyde (GA) combining with heat treatment to cross-link the polymer network.

The geometries and relative stabilities of 15 tautomeric forms and the corresponding isomers of the studied molecules have been identified and their relative stabilities are investigated. The potential energy profiles and intrinsic reaction coordinates (IRC) calculations along the proton transfer coordinates both in the ground and in the excited state are monitored as well. The impact of the donating (OMe) and withdrawing (NO2) groups on the single and double proton transfers are investigated both in the gas phase and solution.

Ebook "Solid base catalysis (Springer series in Chemical physics, Volume 101)" is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems.

The results show that the O atom, as compared to the S, Se, and Te ones acting as proton acceptors, plays a peculiar role in the C-H blue shift of stretching frequencies involving hydrogen bonds. It is found that the magnitude of red- or blue-shift of the C-H stretching frequency in the hydrogen bond is mainly determined by the C-H polarity (DPE) and gas phase basicity (PA) of the proton acceptor in the isolated isomer, besides relevant weak interactions and the geometrical structure of the formed complex.

The advanced oxidation processes (AOPs) were commonly used in textile dyeing wastewater treatment due to its ability to rapidly degrade dyed compounds. However, its disadvantage is the limited dispersion of ozone in wastewater. To minimize the disadvantage, it is necessary to improve the gas-liquid phase contact to maximize the dispersion of ozone in the wastewater body.
