High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

Advanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

BLADE‐ON‐PETIOLE Genes Enable Genetic Bottleneck Mitigation Through Cross‐Species Repurposing of Floral Persistence Traits

Advanced Science, EarlyView.
This study shows that BLADE‐ON‐PETIOLE (BOP) proteins regulate floral abscission and senescence in tomato by interacting with TFAM1 to form transcriptional condensates controlling the ARABIDOPSIS THALIANA HOMEOBOX GENE 1 (ATH1)‐mediated abscission pathway.

Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

Angewandte Chemie, EarlyView.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.
