a total of 400 bovine diarrhoeic fecal specimens were obtained and conventional microbial culture, immunomagnetic separation and multiplex pcr were simultaneously carried out on samples. for detection of salmonella at genus level, inv-a universal primer was selected. in order to identifiing of salmonella typhimurium, specific primers of rfbj, fljb and flic related to gene sequence of o4, h2:1,2...

Hydrogen (H2) is known for its clean energy characteristics. Its separation and purification to produce high-purity H2 becoming essential promoting a economy. There are several technologies, such as pressure swing adsorption, membrane, cryogenic, which can be adopted H2; however, each standalone technology has own pros cons. Unlike technology, the integration of technologies shown significant p...

This work addresses the use of TiO2-based particles as an intermediate layer for reaching fully dense Pd-membranes by Electroless Pore-Plating long-time hydrogen separation. Two different layers formed raw and Pd-doped TiO2 were considered. The estimated Pd-thickness composite membrane was reduced in half when ceramic doped with Pd nuclei before their incorporation onto porous support vacuum-as...

Hydrogen permeation membranes are a key element in improving the energy conversion efficiency and decreasing the greenhouse gas emissions from energy generation. The scientific community faces the challenge of identifying and optimizing stable and effective ceramic materials for H2 separation membranes at elevated temperature (400-800 °C) for industrial separations and intensified catalytic rea...

Histamine membrane receptors are defined as either H1 (blocked by diphenhydramine-like antagonists) or H2 (blocked by cimetidine-like agents). We now report the solubilization, separation, and partial characterization of specific H1 and H2 membrane receptors from calf thymocytes. Membrane fragments were incubated with [3H]histamine either alone or with unlabeled histamine, diphenhydramine, or c...

Multiple theories on hydrogen isotope fusion in Pd metal have been developed over the years. Among other important factors, the high concentration of H(D) atoms and their close proximity to each other within a host lattice are important. We use numerical modeling to investigate conditions favorable to lower H-H (D-D) separation. This separation depends on the background charge density within th...

A new type of graphitic C3N4-based composite photocatalysts was designed and prepared by co-loading PEDOT as a hole transport pathway and Pt as an electron trap on C3N4. The as-prepared C3N4-PEDOT-Pt composites showed drastically enhanced activity for visible light-driven photocatalytic H2 production compared to those of C3N4-PEDOT and C3N4-Pt, possibly due to the spatial separation of the redu...

Biogas is mainly composed of CH4 and CO2, so it used as an alternative energy to with high density by separating removing CO2 from biogas. In addition, can be utilized producing synthesis gas (CO H2) through thermal decomposition biogas or synthesizing methanation CO2. The technique a method that improve the concentration without separation. This study aims produce more efficient methane over N...
