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

Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm [PDF]
Nature Astronomy, 2017 Type II supernovae are the final stage of massive stars (above 8 M⊙) which retain part of their hydrogen-rich envelope at the moment of explosion. They typically eject up to 15 M⊙ of material, with peak magnitudes of −17.5 mag and energies in the order ...

Martian atmospheric hydrogen and deuterium: Seasonal changes and paradigm for escape to space
Science AdvancesMars’ water history is fundamental to understanding Earth-like planet evolution. Water escapes to space as atoms, and hydrogen atoms escape faster than deuterium giving an increase in the residual D/H ratio.

A new sustainable hydrogen clean energy paradigm
International Journal of Hydrogen Energy, 2018 Abstract We analyze the feasibility of a novel, hydrogen fuel cell electric generator to provide power with zero noise and emissions for myriad ground based applications. The hydrogen fuel cell electric generator utilizes a novel, scalable apparatus that safely generates hydrogen (H2) on demand according to a novel method, using a controlled chemical

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.

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 ...
