Prevalence of COVID -19 Pandemic: A Paradigm Shift to Hydrogen Economy [PDF]
Engineering and Technology Research Journal, 2020 Covid-19 pandemic lockdown has slow down the world economic system. The pandemic has cleared the roads, close factories and grounded planes causing severe economic challenges. The damaging impact of the pandemic amid lockdown has been a blessing in guise for the environment because of significant drop in pollution level as transport and industrial ...

Myoglobin: The hydrogen atom of biology and a paradigm of complexity [PDF]
Proceedings of the National Academy of Sciences, 2003 In a tour de force in this issue of PNAS, Bourgeois et al. (1) have used 2.2-ns x-ray pulses to observe the motion of carbon monoxide (CO) through myoglobin (Mb) and the relaxation of the protein from 3.2 ns to 3 ms after photodissociation. This work follows the pioneering experiments of Moffat and collaborators (2). It demonstrates how far advances in

Nitric oxide and hydrogen sulfide: the gasotransmitter paradigm of the vascular system [PDF]
British Journal of Pharmacology, 2017 There are several reviews on NO and hydrogen sulfide (H2S) and their role in vascular diseases in the current relevant literature. The aim of this review is to discuss, within the limits of present knowledge, the interconnection between these two gasotransmitters in vascular function.

Molecular chemisorption: a new conceptual paradigm for hydrogen storage
Chemical Synthesis, 2022 Developing efficient hydrogen storage materials and the corresponding methods is the key to successfully realizing the “hydrogen economy”. The ideal hydrogen storage materials should be capable of reversibly ab-/desorbing hydrogen under mild temperatures with high hydrogen capacities.

Midazolam Efficacy Against Acute Hydrogen Sulfide-Induced Mortality and Neurotoxicity. [PDF]
, 2018 Hydrogen sulfide (H2S) is a colorless, highly neurotoxic gas. It is not only an occupational and environmental hazard but also of concern to the Department of Homeland Security for potential nefarious use. Acute high-dose H2S exposure causes death, while

Lewis Acid–Water/Alcohol Complexes as Hydrogen Atom Donors in Radical Reactions
CHIMIA, 2013 Water or low molecular weight alcohols are, due to their availability, low price and low toxicity ideal reagents for organic synthesis. Recently, it was reported that, despite the very strong BDE of the O–H bond, they can be used as hydrogen ...
