Hydrogen and a New Paradigm for Electricity Storage
2019 Offshore Energy and Storage Summit (OSES), 2019A new paradigm is needed for electricity storage in the renewables energy market. Today, what passes for “grid storage” are technologies that provide, at most, eight to 12 hours of discharge. If we are to successfully go to 100% renewables and to wean electricity generation from fossil fuels, we need storage to have up to 592 hours (88,800MWh/150MW ...

Hydrogen Exchange Kinetics of RNase A and the Urea:TMAO Paradigm
Biochemistry, 2003A key paradigm in the biology of adaptation holds that urea affects protein function by increasing the fluctuations of the native state, while trimethylamine N-oxide (TMAO) affects function in the opposite direction by decreasing the normal fluctuations of the native ensemble.

Proton and hydrogen atom transfer in hydrogen bonded clusters: Ammonia as a paradigm
The Journal of Chemical Physics, 1997The competition between proton and hydrogen atom transfer in ammonia clusters is studied in the excited C̃′ state using femtosecond pump-probe spectroscopy. Little effect of solvation is seen for the case of proton transfer, while the hydrogen transfer processes display significant dependence on the degree of clustering.

A Metabolic Paradigm for Hydrogen Sulfide Signaling via Electron Transport Chain Plasticity
Antioxidants & Redox Signaling, 2023Significance: A burgeoning literature has attributed varied physiological effects to hydrogen sulfide (H2S), which is a product of eukaryotic sulfur amino acid metabolism. Protein persulfidation represents a major focus of studies elucidating the mechanism underlying H2S signaling.

The Green Hydrogen Paradigm Shift
Cogeneration & Distributed Generation Journal, 2007The change from a global economy dependent upon fossil fuels torenewable fuels for an hydrogen economy is occurring now. Not in 50 to60 years, but the hydrogen economy is underway today. This “paradigmshift” is one as signi ficant and dramatic as the Industrial Revolutionitself.

Tech-integrated paradigm based approaches towards carbon-free hydrogen production
Renewable and Sustainable Energy Reviews, 2018Abstract Because of the predicted energy crisis and increasing concerns about high carbon emissions, identifying and building sustainable energy systems has been the focus of recent energy research, with the idea of a viable “hydrogen economy” becoming increasingly popular. This paper provides functional guidance for the transition from a fossil fuel-

A New Paradigm in Pincer Iridium Chemistry: PCN Complexes for (De)Hydrogenation Catalysis and Beyond
Accounts of Chemical Research, 2022The discovery and development of organometallic catalysts is of paramount importance in modern organic synthesis, among which the ligand scaffolds play a crucial role in controlling the activity and selectivity. Over the past several decades, d8 transition-metal complexes of pincer ligands have been developed extensively thanks to their easy structural

Paradigms and paradoxes: organic thermochemistry without hydrogen: carbon oxides and nitrides
Structural Chemistry, 2008All organic compounds contain carbon. Most contain hydrogen. This brief study discusses the enthalpy of formation of a collection of organic compounds containing only oxygen or nitrogen accompanying the carbon.

Journal of The Electrochemical Society, 2020
Herein, we advance our fundamental understanding of hydrogen electrochemistry as crucial energy technology by challenging the century-long paradigm that Volmer, Heyrovsky, and Tafel reactions are elementary. We identify and resolve the theoretical controversy of this phenomenological model to argue that each reaction must be stepwise not concerted ...

Yolk-shell nanostructures as an emerging photocatalyst paradigm for solar hydrogen generation
Nano Energy, 2019Abstract With porous shells and mobile cores, yolk-shell nanostructures provide great structural advantage for mass transport-related applications such as photocatalysis. In this work, Au–Cu7S4 yolk-shell nanostructures are synthesized from Au–Cu2O core-shell templates.
