Engineering Oxygen Vacancy in Support to Promote Activity of In2O3 Catalyst for CO2 Electroreduction to Formate

Advanced Functional Materials, EarlyView.
A novel approach by depositing In2O3 onto an oxygen vacancy (OV)‐enriched support, ceria‐zirconia solid solutions (CZ), to activate synergistic effects is proposed. The OV contributes greatly to the dissociation of H2O and further promotes the hydrogenation of adsorbed CO2 species.

MESA and NuGrid simulations of classical novae: CO and ONe nova nucleosynthesis [PDF]

, 2014
Classical novae are the result of thermonuclear flashes of hydrogen accreted by CO or ONe white dwarfs, leading eventually to the dynamic ejection of the surface layers.

Liquid Metals as Initiators of Free‐Radical Polymerization of Hydrogels: A Perspective

Advanced Functional Materials, EarlyView.
Gallium‐based liquid metals initiate free radical polymerization to form hydrogels without the use of toxic molecular initiators. In addition to initiating polymerization, they can act as crosslinkers, yielding softer, more extensible, and tougher hydrogels than those formed with conventional initiators.

Phase‐Stable Palladium Hydride Derived from PdCoO2 for Sustainable Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
The exceptionally active β‐PdHx is demonstrated for the hydrogen evolution reaction in acidic media. The fast activation kinetics from the PdCoO2 template are resolved by operando spectroscopy, and isotope‐labeled atom probe tomography quantifies the H content in β‐PdHx. The outstanding stability of the electrocatalyst is attributed to the retention of

Bipolar Hydrogen Production by Hybrid Water Electrolysis

Advanced Functional Materials, EarlyView.
This review focuses on the recent advances in uniqueness bipolar H2 production from the oxidation of representative small molecules, including 5‐hydroxymethylfurfural, formaldehyde, alcohols, and N‐heterocycle amides. The target electrocatalysts and the underlying mechanisms are discussed in respect to specific substrate oxidation.
