Adsorption of alkanols on the strontium titanate surface leads to a two-state chemisorption equilibrium mediated by gas–surface hydrogen bonding. This equilibrium is used to develop a paradigm of interfacial Brønsted–Lowry acidity of alkanols.

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 ...

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

The hydrogen paradigms. Technologies, country patterns of specialisation and dependence
The adverse effects of the climate crisis call for a structural change in the economy toward less environmentally disruptive development pathways. To address decarbonisation, hydrogen seems to be the most promising element to complement renewable energy.Negro, Beatrice +2 more

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.

The peer-to-peer paradigm applied to hydrogen energy distribution
IEEE EUROCON 2009, 2009The shift from centralized power plants to fully distributed generation, storage and provision of energy may be the greatest innovation of next decades. To succeed, it must be supported by the completion of the decarbonization process, using hydrogen as main energy carrier.

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.

cis-Delivery of H2 to the π-system of an unsaturated substrate is the canonical course of metal catalyzed hydrogenation reactions. The semireduction of internal alkynes with the aid of [Cp*Ru]-based catalysts violates this rule and affords E-alkenes by direct trans-hydrogenation.
