Oxidative vaporization kinetics of chromium (III) oxide in oxygen from 1270 to 1570 K [PDF]
Rates of oxidative vaporization of Cr2O3 on preoxidized resistively heated chromium were determined in flowing oxygen at 0.115 torr for temperatures from 1270 to 1570 K.

Carbon Energy, EarlyView.ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Carbon Energy, EarlyView.Spatial structural self‐regulation strategy stimulates the conversion of the hydroxy group (–OH) in starch into carbonyl (–C=O) within a stable three‐dimensional cross‐linking structure. This structure not only reduces the production of water and volatile products, thereby preventing foaming during pyrolysis and improving carbon yield, but also ...

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production
Carbon Energy, EarlyView.Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Photothermal CO2 Hydrogenation: Reactions, Mechanisms, and Catalyst Design
Carbon Energy, EarlyView.Reactions, mechanisms, and catalyst design for photothermal CO2 hydrogenation. ABSTRACT Photothermal CO2 hydrogenation has attracted extensive attention because it provides a green and sustainable approach to fuel and chemicals production. The photothermal catalyst plays a critical role in CO2 conversion through a range of reactions.

Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods
Chemistry – A European Journal, EarlyView.We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy
Chemistry – A European Journal, EarlyView.Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.
