Background: There is an enormous growth in the epoxidation base on vegetable oils in recent years due to the rising demand for eco-friendly epoxides to replace petrochemical resources. Objective: The aim of this review is to give an insight on the articles on epoxidation of various vegetable oils published in scientific journals major proceedings and books. The major area research have been identified and discussed Read More

Background and Objective: Li3InBr6-yXy (X=F, I) was synthesized and the substitution effect on ionic conductivity was investigated. Method: An all solid state secondary battery was fabricated using Li3InBr6-yXy (X=F, Cl, I) and evaluated. Li3InBr6-yFy was single phase at y ≤ 3. The lattice constants for both compounds were decreased with an amount of F. The conductivity of Li3InBr6-yFy was decreased with y and electroc Read More

Background and Objective: In this work, the precipitation combined with vacuum drying and supercritical CO2 drying was applied in the preparation of Mg(OH)2 which was thermally decomposed to MgO. Results: Results showed that the constant dropping rate of Mg(NO3)2 solution into NaOH aqueous solution under 90°C with a relatively high pH of 10.1 led to the MgO powder with high specific surface area and large pore volu Read More

Objective: Aim of this paper is to investigate the interactions between industrial-grade polycarboxylate ether (PCE) polymers and ordinary Portland cement to assess whether is possible to draw structure/performance relations for impure, yet fully characterized, polymers. Method: To this end thirteen PCE polymers were synthesised in industrial fashion, deeply analyzed and tested in cement paste. Chemical stability and adsorp Read More

Objective: In this work, the synthesis of polycarboxylate ethers (PCE) via partial esterification of acrylic copolymers has been experimentally carried out with the aim of obtaining results useful to the development of a reliable kinetic model. Method: Experimental tests were conducted starting from monomethyl ether polyethylene glycol (MPEG) as side chain, and two acrylic backbones of different constitution. The reactions wer Read More

Background: In the current study, nanocrystalline thin films of TiO2:xSiO2 (x: mole percentage) with high photocatalytic activity were grown on glass surfaces using sol-gel method. The films were then treated under high temperature of 500°C for the crystal growth. The synthesized films presented high photocatalytic activity when they were in contact with methyl orange (MO) solution and UV irradiation. Due to complexity Read More
