Microfluidic Architecting of Patchy MXene Core‐Shell Particles for Ultralow‐Loading Photothermal Shape‐Memory Actuation

Advanced Functional Materials, EarlyView.
Spatially distributing Ti3C2Tx nanosheets into core‐shell architecture, rather than as directly dispersed flakes, mitigates aggregation and enhances photon harvesting. When the Ti3C2Tx core‐shell particles are incorporated into a shape‐memory polymer matrix at an ultralow loading of 0.0024 wt%, the improved photothermal conversion translates into ...

Beyond Primary Nucleation: Molecular Basis of Peptide Crystal Secondary Nucleation at Soft Interface

Advanced Functional Materials, EarlyView.
High spatiotemporal‐resolution atomic force microscopy directly resolved peptide secondary nucleation (SN) and growth characteristics and mechanisms on HOPG. The landscape of peptide nucleation sites, growth dynamics, molecular‐scale structures, phase transitions, and cross‐seeding processes were realized.

GDNF‐Enriched Small Extracellular Vesicle‐Loaded ROS‐Scavenging Hydrogel Promotes Neural Regeneration After Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
A glial cell line‐derived neurotrophic factor (GDNF)‐enriched small extracellular vesicle‐loaded reactive oxygen species (ROS)‐scavenging hydrogel integrates sustained neurotrophic delivery with local modulation of oxidative and inflammatory stress after spinal cord injury. The composite hydrogel improves local vesicle retention, protects neural tissue,

rADSC-loaded tubular units composed of multilayer electrospun membranes promoted bone regeneration of critical-sized skull defects

Materials Futures
Adipose-derived stem cells (ADSCs) have considerable potential for bone regeneration. However, their performance is limited by a lack of scaffolds that adequately mimic the hierarchical structure of bone to promote proliferation and osteogenic ...

Assessing recall of personal sun exposure by integrating UV dosimeter and self-reported data with a network flow framework.

PLoS ONE, 2019
BackgroundMelanoma survivors often do not engage in adequate sun protection, leading to sunburn and increasing their risk of future melanomas. Melanoma survivors do not accurately recall the extent of sun exposure they have received, thus, they may be ...
