Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

A Co‐Self‐Assembled Monolayer With Enhanced Coverage and Defect Passivation for Efficient Inverted Perovskite Solar Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved a co‐self‐assembled monolayer (Co‐SAM) with more uniform coverage on nickel oxide substrates and enhanced passivation of buried interfaces by incorporating 4PABCz into Me‐4PACz. Perovskite solar cells fabricated with this Co‐SAM achieved an efficiency of 26.33% and exhibited enhanced stability. The combination of nickel oxide (NiOx)

Super-Jeans Fragmentation and Supply-limited Accretion: Environment-dependent Coevolution of Low- and High-mass Cores

The Astrophysical Journal
Protostellar core formation and growth in high-mass star-forming regions remain key to understanding massive star birth. We analyze the masses of 839 cores (resolved at scales of a few thousand au) from the ASHES project targeting 39 massive infrared ...

An Adaptive Thin Cloud Removal Method for Mitigating Bright Surface Interference

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
A thin cloud thickness map (TCTM) is crucial for thin cloud removal tasks, but accurately estimating the TCTM can be a significant challenge. The TCTM is highly susceptible to buildings, which are unavoidable.

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Multifunctional Oleylamine Enables Direct Regeneration of Spent Lithium Iron Phosphate Cathodes through Coupled Lattice and Interface Repair

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional oleylamine‐assisted solvothermal strategy is introduced for coupled lattice and interface repair of S‐LFP cathodes. Benefiting from its strongly coordinating amine groups and long hydrophobic alkyl chains, oleylamine simultaneously acts as an intrinsic reductant, defect‐repair mediator, morphology stabilizer, and carbon/nitrogen ...

Photostabilized halocyanine for near-infrared excited bimodal photothermal synergism and tumor-targeted therapy. [PDF]

Smart Mol
A series of halogenated organic small molecules were prepared by substituting hydrogen atoms in BC7 molecules with halogen atoms. These chemically modified derivatives displayed significantly improved stability, warming efficiency, and reactive oxygen species generation ability. BC7‐Br and BC7‐Cl showed remarkably enhanced therapeutic efficacy relative
