Heterogeneous supported catalysts are often synthesized by impregnation or precipitation methods. Recently, melt infiltration has emerged as an alternative method that allows high metal loadings and eliminates the need for a solvent, but challenges arise regarding control over particle size distribution. In this work, synthesis of silver is explored. The narrow pore distribution chosen ordered ...

Within the frame of this work, synthesis silver nanoparticles (Ag NPs) and chloride (AgCl as mediated by microbes has been investigated. The were reduced from a nitrate precursor presence bacteria, like Raoultella planticola Pantoea agglomerans. results show that characteristic surface plasmon resonance absorption band occurs at about 440 nm. Nanoparticles also characterized with help scanning ...

Peripheral nerve myelin contains a dominant low molecular weight glycoprotein called Po. To study the metabolism of this glycoprotein, tritiated fucose was injected into the peripheral nerves of adult mice and developing rats, and the temporal distribution of label was examined by autoradiography and gel electrophoresis. Mice and rat pups, injected with fucose, were sacrificed from 1 h to 98 da...

The transcriptional activity during meiotic prophase in the mouse testis is studied with light microscopy and high-resolution autoradiographic techniques using [(3)H]uridine as a labeled precursor. In the present study, two types of RNA synthesis are detected during meiotic prophase: an extranucleolar RNA synthesis of perichromosomal localization and a nucleolar RNA synthetic activity. In some ...

In this paper, a facile two-step Galvanic replacement reaction (GRR) is proposed to prepare Pt-Ag tubular dendritic nano-forests (tDNFs) in ambient condition for enhancing methanol oxidation reaction (MOR) under solar illumination. In the first GRR, a homogeneous layer of silver dendritic nano-forests (DNFs) with 10 μm in thickness was grown on Si wafer in 5 min in silver nitride (AgNO3) and bu...

Bacterial leaf blight of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major disease of rice, leading to reduction in production by 10-50%. In order to control this disease, various chemical bactericides have been used. Wide and prolonged application of chemical bactericides resulted in the resistant strain of Xoo that was isolated from rice. To address this problem, we were searching...
