A series of water-soluble chitin-chitosan derivatives is proposed as a bioflocculants. The evaluation of flocculants ability is based on the amount of rubber obtained and the purity of rubber as compared to acetic acid ...

The studies on optical properties of various conductive polymers (i.e., poly(2-methoxy-5-(2 ’-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV), poly(ethylhexyloxy-octyloxy-p-phenylene ethynylene) (EHO-OPPE), poly(2,7-(9, ...

Cloud point extraction (CPE) has been successfully scaled up to continuously remove aromatic contaminants from wastewater in a multi-stage rotating disc contactor. When the nonionic surfactant solution has a temperature ...

The influences of pyrolysis conditions, i.e. pyrolysis temperatures, catalyst temperatures were investigated on the catalytic pyrolysis of waste tire. For the influences of catalysts, the studied parameters were metallic ...

Pyrolysis, thermal decomposition, is applied to simultaneously treat and stabilize sewage sludge. Liquid and solid products are generated and be able to utilized for providing energy and valuable chemicals. Thermal ...

Steam reforming of methanol has been performed on a variety of supported Au catalysts. In this work, the catalysts were prepared by deposition-precipitation (DP) and their catalytic activity were studied in a micro-reactor ...

In past years, many polymers have been applied to electrospinning as pure nanofibers. Interestingly, it has been reported that metal nanoparticles have been incorporated into polymer nanofibers by this process. In this ...

Pseudomonas aeruginosa SP4, isolated from petroleum-contaminated soil in Thailand, was used to produce a biosurfactant from nutrient broth supplemented with palm oil. Normally, crude biosurfactant has been extracted from ...

In this research, lamination technique was used to improve piezoelectric properties of PVDF. Laminated or multilayer system shows unusually high piezoelectricity because of charge interfering at the interface—charge has ...

Alcohol ethoxylates (AEs) produced from natural products (palm oil and coconut oil) have been increasingly considered to replace NPEs (nonylphenol ethoxylates). In this work, the properties of fatty alcohol ethoxylates—C₁₂-₁₄EO₃, ...
