Steric‐Pressure‐Driven Topological Reconstruction for High‐Performance Zintl Phase Thermoelectrics with Machine‐Learning Validation

open access: yesAdvanced Science, EarlyView.
Synergistic Sr and Ag co‐doping drives steric‐pressure‐induced reconstruction from a 2D layered structure to a cross‐linked 3D framework in the Ca9‐xSrxZn4+y‐zAgzSb9 system, enhancing carrier mobility while maintaining a large Seebeck coefficient and doubling ZT to 0.73 at 873 K, with hybrid transfer machine learning further capturing the compositional

Topology‐Driven X‐Shaped DNA as a cGAS Stimulator to Promote Dendritic Cell Activation and Antitumor Vaccine Efficacy

open access: yesAdvanced Science, EarlyView.
X‐shaped DNA promotes multivalent cGAS assembly and enhances cGAS‐STING signaling. When conjugated with antigenic peptides, the resulting X‐DNA‐based peptide vaccine promotes dendritic cell activation, antigen presentation, and antitumor T‐cell responses.

Pairing Non‐Fullerene Acceptors With the Right Polymer: Impact of Phase Morphology and Short‐Range Transport on Charge Generation

open access: yesAdvanced Electronic Materials, EarlyView.
This study investigates polymer requirements for pairing with high‐efficiency non‐fullerene acceptors (NFA) in organic photovoltaics by comparing three polymer blends across varied phase morphologies. The generation of free charges is driven by fast transport‐assisted charge separation combined with slow intrinsic recombination.

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

Reveal Non‐Uniform Passivation on Lithium Metal Anode With Operando Spectroscopic Ellipsometry

open access: yesAdvanced Energy Materials, EarlyView.
In‐operando spectroscopic ellipsometry reveals how nucleation and crystallographic orientation govern the non‐uniform growth of native passivation films on lithium metal. Time‐resolved thickness mapping captures island formation and coalescence, while orientation‐dependent measurements show that the equilibrium film on Li(110) is approximately half as ...

“Lithium‐Free” Anode Solid‐State Batteries Enabled by 3D Structured Miec Garnet

open access: yesAdvanced Energy Materials, EarlyView.
“Lithium‐free” anode solid‐state batteries can maximize energy density by eliminating excess lithium metal but are limited by unstable lithium nucleation and poor lithium reversibility at solid interfaces. A mixed ionic and electronic conducting garnet scaffold promotes uniform lithium deposition within a three‐dimensional porous framework at low ...
