Multimodal Cross‐Attentive Graph‐Based Framework for Predicting In Vivo Endocrine Disruptors
Advanced Science, EarlyView.A multimodal cross‐attentive graph neural network integrates molecular graphs with androgen and estrogen adverse outcome pathway (AOP)–anchored in vitro assay signals to predict in vivo endocrine disruption. By fusing information on Tier‐1 AOP logits with chemical structures, the framework achieves high accuracy and provides assay‐traceable ...

Advanced Energy Materials, EarlyView.This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Advanced Energy and Sustainability Research, EarlyView.This study explores Cs2PtX6 (X = Cl, Br) lead‐free perovskites as sustainable photocatalysts for solar‐driven water splitting. Cs2PtBr6 outperforms Cs2PtCl6 in oxygen evolution due to its narrower bandgap and efficient charge carrier dynamics, enabling enhanced light absorption and charge separation.

Angewandte Chemie, EarlyView.This work establishes an MXene‐based S‐scheme heterojunction in which the cooperative interplay among metallic Ni, surface NiOx domains, and conductive Ti3C2Clx drives efficient charge separation and photothermal coupling. Progressive evolution of Ni surface states regulates the CH4/CH3OH product distribution by modulating interfacial energetics and ...

Repertori bibliogràfic sobre "Antropologia filosòfica" (1990-1996) [PDF]
La filosofia de la ciència que va imperar en els anys quaranta-cinquanta era, bàsicament, un intent "asèptic" de reconstruir i formalitzar teories científiques.
