Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

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 ...

Synergistic Remodeling of Tumor Immune Microenvironment via a DNA Nanodevice Integrating STING Activation and Lysosome‐Targeted PD‐L1 Degradation

Advanced Science, EarlyView.
A rational design DNA nanoplatform not only achieves efficient PD‐L1 degradation but also triggers robust STING signaling. The nanodevice effectively reprograms “cold” tumors, leading to potent inhibition of tumor growth and metastasis in vivo. ABSTRACT The cGAS‐STING pathway is a cornerstone of innate antitumor immunity; however, its therapeutic ...

Beyond d‐Band Catalysis: A Critical Review and Descriptor Framework for Rare‐Earth Engineering in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
