Side Chain Elimination Enables Low‐Cost Fused‐Ring Acceptors and Reveals a Compact Tetrameric Structure for High‐Photocurrent Organic Solar Cells

Advanced Science, EarlyView.
β‐side chain elimination enables cost‐effective fused‐ring acceptors, JSM5 and JSM6, with simplified synthesis. The observed compact tetrameric structures induced by S···N intermolecular interactions lead to 3D charge transport and enhance intermolecular connectivity, delivering high short‐circuit current density up to 28 mA cm−2, a step closer to the ...

Multifaceted Roles of Tantalum in Promoting the Thermoelectric Performance of Mg3(Sb,Bi)2 Based Materials

Advanced Science, EarlyView.
A multifunctional tantalum incorporation strategy enables simultaneous tuning of carrier concentration, mitigation of grain‐boundary scattering, and enhanced phonon scattering in Mg3(Sb,Bi)2. These synergistic effects markedly improve carrier mobility and suppress lattice thermal conductivity, yielding both high material zT and high module conversion ...

Heat Shock Protein 90: From Molecular Chaperone Function to Therapeutic Targeting in Malignancies

Advanced Science, EarlyView.
In this review, an integrated conceptual framework linking HSP90's molecular chaperone functions to its pathological roles in cancer is proposed. HSP90 serves as a central node that integrates oncogenic signaling, buffers proteotoxic stress, maintains cancer stem cell plasticity, and shapes tumor‐immune interactions, all of which converge to drive ...

Large Language Model‐Informed Dual‐Track AI Framework for the Synergistic Design of Crack‐Free and High‐Strength Superalloys

Advanced Science, EarlyView.
This paper illustrates a knowledge‐augmented dual‐track AI framework for advanced superalloy design. First, Large Language Models translate metallurgical heuristics into explicit rules to rapidly prune a vast compositional search space. Subsequently, LLM‐distilled priors safely guide a reinforcement learning agent during autonomous process optimization,

Computation‐Guided Control of Excited‐State Deactivation through Modulation of Conical‐Intersection Accessibility by Donor–Acceptor Asymmetry in Bridged Stilbene AIE Luminogens

Advanced Science, EarlyView.
Donor–acceptor asymmetry modulates conical‐intersection accessibility and topology in bridged stilbenes, providing mechanistic insight into excited‐state deactivation and aggregation‐induced emission (AIE). ABSTRACT A computation‐guided investigation of asymmetric donor–acceptor bridged stilbenes reveals structure–property relationships governing ...
