A two dimensional finite element model (FEM) was developed to Predict the temperature distribution in coal particles with the aid of microwave heating. However, transient temperature profile for coal particles of high dielectric loss factor is obtained when exposed to microwave radiation. The heat equation and Maxwell’s equation are simultaneously solved using the finite element method to predi...

A microwave-H2O2 process for sludge pretreatment exhibited high efficiencies of releasing organics, nitrogen, and phosphorus, but large quantities of H2O2 residues were detected. A uniform design method was thus employed in this study to further optimize H2O2 dosage by investigating effects of pH and H2O2 dosage on the amount of H2O2 residue and releases of organics, nitrogen, and phosphorus. A...

AIMS To assess the effect of microwave heating on immunohistochemical staining of CD15 and CD30 antigens in Hodgkin's disease tissue samples. METHODS Formalin fixed, paraffin wax embedded sections from 20 cases of Hodgkin's disease (six mixed cellularity, 14 nodular sclerosis) were immunostained for CD15, using two antibodies (DAKO-M1 and Leu-M1) and for CD30 using the antibody Ber-H2. The st...

Conventional dyeing processes currently practiced in the textile industry have a great environmental impact, mainly relation to quantity and pollution of water, use toxic chemicals, atmospheric emissions, high energy consumption. This study aims discuss relationship between variables that involve conventional issues. It presents mapping materials emerging technologies for ecological coloration,...

The effects of H2 flow rate during plasma pretreatment on synthesizing the multiwalled carbon nanotubes (MWCNTs) by using the microwave plasma chemical vapor deposition are investigated in this study. A H2 and CH4 gas mixture with a 9:1 ratio was used as a precursor for the synthesis of MWCNT on Ni-coated TaN/ Si(100) substrates. The structure and composition of Ni catalyst nanoparticles were i...
