Bifunctional catalysts are often used in multiple reactions to synthesize certain products. The catalytic activity of bifunctional catalysts is influenced by parameters such as crystallinity, specific surface area, metal distribution, and morphology. Bifu... see more

Researches about the effects of aging time toward crystallinity of products in the synthesis of mesoporous silicates MCM-41 have been done. MCM-41 was synthesized by hydrothermal treatment to the mixture of sodium silicate, sodium hydroxide, cetyltrimetyl... see more

Micro-fibrillated cellulose (MFC) derived from natural fibre is continuously gaining interest to produce an environmentally-friendly material, due to economic and ecological reasons. In consequence, sorghum is one of the most-cultivated crops that usually... see more

MOF-5 (metal-organic frameworks-5) have been synthesized using solvothermal method in which reaction mixtures of zinc nitrate hexahydrate and 1,4-benzenedicarboxylic acid (BDC) in dimethylformamide (DMF) were heated at various heating temperatures and tim... see more

Field emitters can be used as a cathode electrode in a cathodoluminescence device, and single-walled carbon nanotubes (SWCNTs) that are synthesized by arc discharge are expected to exhibit good field emission (FE) properties. However, a cathodoluminescenc... see more

The work investigated in this paper focused on the fabrication of WO3 films by the spray pyrolysis technique, and different analyses were made to find optimized samples for studying properties suitable for the application of gas sensing. The substrate tem... see more

The oil shale ash, by-product of the Petrosix process, was used as raw material to synthesize zeolite-type materials. The synthesis procedure was the alkaline fusion followed by refluxing, with three different starting material compositions. Two products ... see more

Cassava starch filled linear low-density polyethylene (LLDPE) films are made in order to make plastics which environmentally friendly. The use of compatibilizer ethylene - acrylic ester - maleic anhydride polymerized is needed to obtain a compatible mixtu... see more

In this work, the crystalline carbon nitride photocatalysts were synthesized by an ionothermal technique with varied synthesis temperature of 500, 550, and 600 °C, and synthesis time of 2, 4, and 6 h. Fourier transform infrared spectra showed the successf... see more
