The need to safeguard our planet by reducing carbon dioxide emissions has led a significant development of research in the field alternative energy sources. Hydrogen proved be most promising molecule, as fuel, due its low environmental impact. Even if various methods already exist for producing hydrogen, them are not sustainable. Thus, focuses on biological sector, studying microalgae, and othe...

BACKGROUND This was a head-to-head comparison of two hydrogen-peroxide-based room decontamination systems. AIM To compare the efficacy, efficiency and safety of hydrogen peroxide vapour (HPV; Clarus R, Bioquell, Andover, U.K.) and aerosolized hydrogen peroxide (aHP; SR2, Sterinis, now supplied as Glosair, Advanced Sterilization Products (ASP), Johnson & Johnson Medical Ltd, Wokingham, U.K.) r...

The Front Cover shows an “O2 grasshopper” captured by two “Copper scorpions” using their strong claws and tails (outer-sphere hydrogen bonds). As the key intermediate in biological oxygenation, trans-1,2-peroxodicopper adduct was mimicked a variety of molecular copper complexes. structure-activity models hydrogen-bond-assisted tetradentate copper(I) chloride complexes were established, fundamen...

Statement of Purpose: The aim of this study is to develop highly functional biomimetic scaffolds with specific bioactivity by using novel porogen and plasma treatment for cartilage tissue engineering. Solid hydrogen peroxide compounds, such as urea hydrogen peroxide and sodium percarbonate are well-known commercial products used as a bleaching agent, antiseptic and disinfectant. Urea hydrogen p...

Biological hydrogen is one of the most promising alternative energy and fuel resource today. Due to the ability of several naturally occurring microorganisms to generate hydrogen using different metabolic processes, engineered biohydrogen production is considered a feasible and sustainable technology. To improve upon current technological applications, biological and metabolic engineering appro...

We present the synthesis, properties, and biological applications of Peroxyfluor-1 (PF1), a new type of optical probe for intracellular imaging of hydrogen peroxide in living biological samples. PF1 utilizes a boronate deprotection mechanism to provide unprecedented selectivity and optical dynamic range for detecting H2O2 in aqueous solution over similar reactive oxygen species including supero...

Syed, M., Soreanu, G., Falletta, P. and Béland M. 2006. Removal of hydrogen sulfide from gas streams using biological processes A review. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 48: 2.1 2.14. Hydrogen sulfide (H2S) is a toxic and odorous compound present in biogas produced by the anaerobic digestion of biosolids and other organic materials. Due to its corrosive nature...

We report a hybrid chem-biological system, coupling photovoltaic hydrogen production, chemical CO 2 hydrogenation, an artificial carbon conversion pathway and the natural PHB synthesis pathway, which drove completely closed-loop economy for production.

We have developed a novel colorimetric and ratiometric fluorescence probe for the selective and sensitive monitoring of hydrogen sulfide based on a dicyanoisophorone platform. An excellent linear relationship of fluorescence intensity ratio (I637/I558) (R(2) = 0.9867) versus hydrogen sulfide concentration in the range of 1-12 μM was obtained. This probe exhibited a remarkable fluorescence respo...
