Photoelectrocatalytic Diazidation of Olefins via Synergistic Dual Iron Species

open access: yesAdvanced Science, EarlyView.
We report a simple and general approach for 1,2‐diazidation of alkenes by a photoelectrochemical strategy using TMSN3 as an azide source. This transformation proceeds using earth‐abundant iron under mild reaction conditions. It displays broad functional group compatibility and accommodates diverse alkene types‐including unactivated, activated, electron‐

Interfacial and Hydration‐Associated Lithium Retention During FePO4 Regeneration from Spent LiFePO4 Cathodes

open access: yesAdvanced Science, EarlyView.
During iron phosphate regeneration, sequential washing distinguishes lithium fractions by accessibility: approximately 70% of precipitate‐associated lithium is washing‐removable, while approximately 30% remains after three cycles. Comparisons of simulated and practical systems associate retained lithium with hydrated amorphous Fe‐O‐P environments ...

Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

open access: yesAdvanced Energy Materials, EarlyView.
This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Ether‐Based Electrolytes and the Solvation Structure in Sodium Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Ether electrolytes enable high‐performance sodium‐ion batteries through their unique physicochemical properties, particularly distinctive solvation structures and co‐intercalation behavior. However, the localized solvation structure and its dynamic evolution during electrochemical processes remain a “black box”.

Integrating Perennial Groundcover in Corn and Soybean Acres: Impacts on U.S. Agriculture

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Sustainable agricultural practices such as cover cropping can improve soil health, water quality, and carbon sequestration, yet U.S. adoption remains limited due to economic and operational barriers. We evaluate market and economic impacts of integrating perennial groundcover into U.S.
