Metal doped TiO2 catalysts were synthesized by sol-gel method and their activities were determined for degradation of methyl orang as a pollutant. Nd-doped TiO2 showed the maximum activity comparing with others. Colloidal SiO2 was used as a support to increase the surface area and also the activity. Nano-TiO2/SiO2/Nd was synthesized by sol-gel method and it was characterized using XRD, XRF, SEM...

of Vienna, Vienna, Austria; Floridsdorfer Allergiezentrum, Vienna, Austria. Background: Mung beans (Vigna radiata) contain 2 Bet v 1 related proteins: Vig r 1, a member of the PR-10 subfamily, and cytokinin-specific binding protein (CSBP), a protein with low sequence identity (31%) to Bet v 1. We aimed to compare Vig r 1 and CSBP to Bet v 1 regarding biochemical and immunological properties. Me...

The objective of this study was to explore the influence of pyrolysis temperature on the physicochemical properties of biochar synthesized from durian wood (Durio zibethinus) sawdust. Surface morphological features, including the porosity and BET surface area of biochars, provide appropriate dimensions for growing clusters of microorganisms with excellent water retention capacity in soil. Oxyge...

The effects of preparative parameters on the surface basicity, composition, and transesterification activities of several Ca-La metal oxide catalysts were investigated. Four different preparation methods: ammonia-ethanol-carbon dioxide precipitation, physical mixing, impregnation, and coprecipitation, were studied. It was found that the ammoniaethanol-carbon dioxide precipitation method resulte...

Magnetic hydroxyapatite nanoparticles (MNHAP) adsorbents were synthesized and were used for the removal of Cd2+ and Zn2+ from aqueous solutions. The properties of this magnetic adsorbent were characterized by scanning electron microscopy (SEM), energy dispersive analysis system of X-ray (EDAX), X-ray powder diffraction (XRD) analysis, zeta potential, BET surface area measurements and magnetizat...
