Catalase, one of the antioxidant enzymes, decomposes hydrogen peroxide into water and oxygen. From discovery catalase, several studies have been carried out to reveal its importance in health, food cosmetics industries etc., these are still ongoing. In this study, catalase enzyme was partially purified from muscle tissue Dusky spinefoot (Siganus luridus). Purification procedure consisted homoge...

The purification of the product gas from dehydrogenation liquid organic hydrogen carriers (LOHC) by using PdAg-membranes is highly promising, since low level impurities in released stream allows pressure operation and favours coupling with step. Motivated our recent short-term investigations indicating an influence these on membrane performance behaviour exposure to was investigated detail over...

In this work two alternatives are presented for increasing the purity of hydrogen produced in a membrane reactor ammonia decomposition. It is experimentally demonstrated that either thickness selective layer or using small purification unit permeate membranes, ultra-pure can be produced. Specifically, results show above 6 μm obtained at pressures below 5 bar. A cheaper solution, however, consis...

<p>Abstract— The biogas desulphurization process has a crucial role in the widespread use of due to toxic and corrosive nature element hydrogen sulfide on equipment. This study investigated potential waste welding electrodes as purification medium. Variables form feed flow rates 1, 2, 3 liters/minute were studied for their effects. As result, most optimum performance was obtained test wit...

Alkali atoms trapped in solid hydrogen matrices have demonstrated ultralong electron spin coherence times and are promising as quantum sensors. Their is limited by magnetic noise from naturally occurring orthohydrogen molecules the parahydrogen matrix. In gas phase, component of can be converted to flowing it over a catalyst held at cryogenic temperatures, with lower temperatures giving fractio...

Activated carbon, which is used in many application areas such as gas purification, purification of pollution water and wastewater, removal odor pollution, the defense industry, production protective clothing health sector, was produced from solid products obtained by waste polyethylene terephthalate (wPET) liquefaction that carried out under non-catalytic conditions, reaction time 15-90 min, a...

Phytoremediation is an emerging concept for contaminated soil restoration via the use of resilient plants that can absorb contaminants. The harvested biomass be thermochemically converted to energy carriers/chemicals, linking decontamination with biomass-to-energy and aligning circular economy principles. Two thermochemical conversion steps biomass, both used treatment/exploitation, are conside...

Abstract The feasibility of biphenyl hydrogenation with syngas for hydrogen purification and binding the aim its transportation was demonstrated. Specific features as a promising organic carrier using unsupported Ni–Mo sulfide catalysts were studied. In particular, influence temperature, reaction time, presence water in system, Н 2 /СО gas mixture composition on substrate conversion selectivity...

Hyperpolarization methods in magnetic resonance enhance the signals by several orders of magnitude, opening new windows for real-time investigations dynamic processes vitro and vivo. Here, we propose a field-independent para-hydrogen-based pulsed method to produce rapidly hyperpolarized 13C-labeled substrates. We demonstrate polarizing carboxylic carbon pyruvate moiety purposely designed precur...
