Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

open access: yesAdvanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.

A Data-Driven Approach for Rathke’s Cleft Cysts Management

open access: yesDiagnostics
Background: Rathke’s cleft cysts (RCCs) are non-neoplastic and rare sellar lesions derived from remnants of Rathke’s pouch. While asymptomatic RCCs often require only conservative management, symptomatic cases may necessitate surgical intervention.

Ultrafast Light‐Driven Electronic and Structural Changes in LaFeO3 Perovskites Probed by Femtosecond X‐Ray Absorption Spectroscopy

open access: yesAdvanced Materials, EarlyView.
Femtosecond X‐ray absorption spectroscopy (fs‐XAS) at PAL‐XFEL captures ultrafast electronic and structural dynamics in epitaxial LaFeO3 thin films. Combined with DFT and multiplet calculations, the study reveals photoinduced ligand‐to‐metal charge transfer, followed by polaron formation and reduced oxygen 2p‐iron 3d hybridization, explaining key ...

Reconfigurable Soft Actuators Constructed via Layer‐by‐layer Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
Stimulated by the energy inputs from heating or humidifying, structural reconfigurations took place in two different materials as manifested by the dynamic structures and mechanical performance, leading to the opportunities of self‐healing and welding. Based on the hierarchical assembly of these two materials with complementary properties, an actuator ...

Vertical Membrane‐Free Organ‐on‐a‐Chip for High‐Throughput In Vitro Studies and Drug Screening

open access: yesAdvanced Materials Technologies, EarlyView.
This novel microfluidic organ‐on‐a‐chip (OoC) platform enables cost‐effective, high‐throughput in vitro modeling. With vertical compartmentalization and gravity‐driven flow, it eliminates porous membranes and external pumps. Successfully generating intestine, cartilage, and tendon models, this study demonstrates drug responses, including 5‐fluorouracil
