Different characterization techniques were used to study the hydrolysis and condensation reaction kinetics of 3-methacryloxypropyltrimethoxysilane (MAPTMS) to obtain open cage silsesquioxane oligomers. The formation of hydrogen bonds, which condition the chemical structures of the resulting products, was identified. Improved thermal and fire resistant behavior of unsaturated polyester (UP) comp...

Ion exchange (IEX) resins can remove natural organic matter (NOM) from drinking water sources. However, the IEX system produces a waste brine rich of sodium, chloride, NOM and sulfate. The treatment aims to recover clean solution sodium that be reused regenerate resin. Previous research showed ceramic nanofiltration partially removes brine, but sulfate removal requires additional treatment. Sul...

In this study, the pitting corrosion susceptibility and its role on the hydrogen embrittlement behavior of AZ80 magnesium alloy were studied using slow strain rate testing (SSRT), electrochemical technique and immersion test method. The electrochemical and immersion tests in chloride-containing solution revealed severe pitting corrosion in the alloy. The SSRT results of the alloy under continuo...

The title compound, C(15)H(14)O(2), was obtained by Friedel-Crafts acyl-ation between 2,5-dimethyl-phenol and benzoyl chloride in the presence of aluminium chloride as a catalyst. The dihedral angle between the benzene rings is 61.95 (4)°. In the crystal, O-H⋯O hydrogen bonding and C-H⋯O weak inter-actions lead to polymeric C(6), C(8) and C(11) chains along the a, b and c-axis directions, respe...

Partially hydrolysed aluminium oxochlorides (ACH) and aluminium-zirconium-glycine oxochlorides (AZG) have been encapsulated using lipophilic carboxylic acids from H,O-silicone solvent systems. The encapsulated materials (E-materials) precipitate out of solution in the form of spherical beads. Their particle size varies with agitation conditions. Distributions from a few tenths to a few hundreds...

Resonant photoexcitation of strontium neon-like ions by the radiation of aluminium hydrogen-like ions is studied theoretically and experimentally in laser-created plasmas. X-ray and X W spectroscopy are used as tools to define plasma conditions where photo-pumping is efficient. The design of targets is completed by ablation studies of strontium layers under various experimental conditions. Abso...

The word "electrocoagulation" (EC) will be sometimes used with "electroflotation" (EF) and can be considered as the electrocoagulation/flotation (ECF) process. Through the process of electrolysis, coagulating agents such as metal hydroxides are produced. When aluminium electrodes are used, the aluminium dissolves at the anode and hydrogen gas is released at the cathode. The coagulating agent co...
