The effectiveness of Co-60 gamma irradiation in controlling citrus red mite (Panonychus citri McGregor) had been proved in our earlier work.However, whether it could be used as an alternative method to replace the current way of quarantine treatment against citrus red mites depends onthe performances of effective doses on citrus fruits. This study was conducted to explore the effects of Co-60 g…
Abstract. Five types of carbon nanotube (CNT) scaffolds were prepared by vacuum filtration of the dispersed single-wall carbon nanotubes (SWCNTs), acid-treated SWCNTs, multi-wall carbon nanotubes (MWCNTs), acid-treated MWCNTs, and amylose-wrapped SWCNTs in water onto porous poly(vinylidene chloride) membranes. The influence of these scaffolds on human cervical carcinoma HeLa cells was inve…
Abstract. In the present work, hydrotalcite-like compound precursor for preparing mixed oxide catalyst was successfully synthesized by a novel method, which was a combination of the reverse microemulsion and coprecipitationmethods. It was observed that the precursor obtained from the above method possessed superior characteristics for preparing mixed oxide catalyst used in ethanol steam re…
Abstract. The interaction between ammonium nitrate based industrial explosives and pyrite-rich minerals in mining operations can lead to the occurrence of spontaneous explosion of the explosives. In an effort to provide a scientific basis for safe applications of industrial explosives in reactive mining grounds containing pyrite, ammonium nitrate decomposition, with and without the presence …
Methane cracking over a bed of Chinese bituminous coal char was studied using a fixed-bed reactor at atmospheric pressure and temperatures between 1073 and 1223 K. Methane conversion over the fresh char increased with increasing temperature to 90% at 1223 K. Hydrogen was the only gas-phase product that was detected during the experimentation. The char was shown to exert a significant catalyt…
