Adsorption and Separation by Flexible MOFs

open access: yesAdvanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Chern--Simons Terms as an Example of the Relations Between Mathematics and Physics [PDF]

open access: yesRelations between Mathematics and Physics (IHES publications 1998), 1998
The inevitability of Chern--Simons terms in constructing a variety of physical models, and the mathematical advances they in turn generate, illustrates the unexpected but profound interactions between the two disciplines.

Nonlocal Conduction in a Metawire

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A 1D metawire composed of twisted copper wires is designed and realized. This metamaterial exhibits pronounced effects of nonlocal electric conduction according to Ohm's law. The current at one location not only depends on the electric field at that location but also on other locations.

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

open access: yesAdvanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Enhanced Polariton Interactions in Suspended WS2 Monolayer Microcavity

open access: yesAdvanced Materials, EarlyView.
Monolayers of transition‐metal dichalcogenides exhibit strong exciton resonances for light‐matter interactions at RT, though substrate effects limit performance. This work presents a planar microcavity with a suspended WS2 monolayer, eliminating substrate‐induced losses.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG
