Interface Modulation of rGO/Bi0/BiOCl Enables Efficient Electron Utilization for CO2 Photoreduction

Small, EarlyView.
A one‐step strategy constructs a coupled rGO/Bi0/BiOCl interface that shifts electron behavior from trapping to dynamic utilization, enabling improved CO2 photoreduction toward hydrocarbon products with enhanced selectivity (92%) toward CH4 and C2H4 and exhibits a 12‐fold increase in CH4 photoreduction activity compared to pristine water made BiOCl ...

Boron‐embedded multifunctional nanoplatform toward potential combined boron neutron capture therapy and immunomodulation in glioma

Smart Molecules, EarlyView.
A brain‐targeting multifunctional nanoplatform (DM&Ce6@COF‐Ang) was engineered by employing boron‐enriched APTES‐COF‐1 as both the therapeutic boron agent and the nanocarrier co‐delivery of DMXAA and Ce6. This nanoplatform achieved synergistic tumor‐specific boron delivery, real‐time pharmacokinetic monitoring, and immunomodulation.

Accelerated Surface Reconstruction in Double Perovskites: Enhancing Oxygen Evolution Reaction Activity Through Fe‐Doping

SusMat, EarlyView.
A novel double perovskite BaSrNi0.9Fe0.1WO6 (BSNFW) is developed with enhanced oxygen evolution reaction (OER) activity owing to synergistic Ni‒Fe interactions occurring through bridging O species. This drives an accelerated surface reconstruction that equilibrates an oxidized and highly active surface configuration in situ, without the need for ...

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

The Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric
