Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System

Advanced Science, EarlyView.
An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Estado da arte da aplicação do processo de hidroesterificação na produção de biodiesel a partir de matérias-primas de baixa qualidade

Revista Principia, 2015
O maior problema encontrado na produção de biodiesel pelos processos convencionais de transesterificação está na aquisição de matérias-primas, que devem ser de acidez e teor de umidade reduzidos, característica atendida pelos óleos vegetais refinados, o ...

Rewiring Pyroptosis to Potentiate Cancer Immunotherapy via a Gasdermin D Agonist Bypassing Caspase‐3

Advanced Science, EarlyView.
This work introduces a small‐molecule agonist, DIBDO, that bypasses Casp‐3 to directly trigger GSDMD‐mediated pyroptosis in tumors. Activated by glutathione, DIBDO generates singlet oxygen and molecular iodine, blocking Casp‐3 pathways and inducing immunogenic cell death.

Engineering Synergistic Intra‐/Intermolecular Conformational Locking via Side‐Chain Branching: A β‐Sheet‐Inspired Strategy for Planar NIR‐II Phototheranostic Aggregates

Advanced Science, EarlyView.
A bio‐inspired side‐chain branching strategy is developed to orchestrate a dual noncovalent conformational locking (NoCL) network, enabling the construction of perfectly planar NIR‐II phototheranostic aggregates. Such structural precision maximizes light‐harvesting efficiency and optimizes exciton dynamics, ensuring synchronized enhancements in NIR‐II ...

Trafficking Deficiency of TMEM175 Variants in Parkinson's Disease Pathogenesis and the Prospects of Precision Medicine

Advanced Science, EarlyView.
This study identifies that the PD‐associated TMEM175‐L156P variant disrupts lysosomal ion channel trafficking by causing aberrant endoplasmic reticulum retention. A “chaperone–agonist” bifunctional small molecule restores TMEM175‐L156P lysosomal localization and channel function, thereby alleviating PD‐relevant cellular phenotypes and highlighting a ...
