Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO 2 Electrolysis in Gas Diffusion Electrodes
ABSTRACT High‐rate electrolysis is commonly assessed using current density, single‐pass conversion and Faradaic efficiency, but these global metrics do not indicate whether the local reaction environment required for selective multicarbon formation is preserved during scale‐up. U...

Valorization of petroleum coke into high-quality few-layer graphene through liquid-phase exfoliation
Abstract Low-value fuel-grade petroleum coke (petcoke), an abundant byproduct from petroleum refining operations, is traditionally used in low-value fuel and metallurgical applications owing to its high carbon content and ability to be used in the synthesis of advanced carbon mat...
- Climate & Environment
Abstract Conventional open-field vegetable production is increasingly constrained by climate volatility and natural resource endowments, creating supply instabilities and shortages that threaten global food resilience and human health. Here, we integrate solar photovoltaics and a...

Peptide-Based Molecular Glues for Targeted Protein Degradation
Targeted protein degradation has transformed drug discovery by replacing occupancy-driven inhibition with event-driven removal of disease-causing proteins, opening previously “undruggable” targets, including transcription factors, scaffolding proteins, and intrinsically disordere...

Effects of Dietary Organic Acid Supplementation in Coccidiosis-Challenged Broilers: A Meta-Analysis
This meta-analysis aimed to systematically assess the effects of organic acid supplementation on growth performance and disease-related parameters in broiler chickens challenged with coccidiosis. Following PRISMA guidelines, a systematic literature search was conducted across Pub...

Identification of a nanosecond isomer of $$^{164}$$Tb
Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Synthesis of WO3/MnO2 Heterojunction Thin Film by AACVD for Photoelectrochemical Water Splitting
Aerosol-assisted chemical vapor deposition (AACVD) was used to prepare a thin film of the heterojunction MnO2/WO3 onto an FTO glass substrate. The WO3/MnO2 heterojunction thin film exhibited a monoclinic WO3 structure characterized by a nanorod-like shape and substantial interfac...
