A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

Advanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Tailoring Oxide/MAX Phase Nanocomposites via Low‐Temperature Oxidation for Lithium‐Ion Battery Anodes: Peeking Behind the Electrochemical Mechanism via In Situ Investigations

Advanced Science, EarlyView.
Controlled oxidation of Ti3Al0.3Sn0.7C2 produces SnO2/TiO2–MAX nanocomposites with superior electrochemical performance. The SnHigh_Ox700 sample shows optimal stability, capacity (300 mAh g−1), and reversibility (99.2%). Its unique morphology ensures efficient charge transport and stress accommodation. In situ analyses reveal reversible SnO2 conversion/

Flash Photodynamic Therapy – How the Saturation of Photosensitizer Absorption Enables Selective and Deeper Tumor Treatments

Advanced Science, EarlyView.
FLASH‐PDT uses strongly‐absorbing photosensitizers and pulsed lasers to saturate the photosensitizer absorption at ≈1‐cm tissue depths. This allows for the generation of [ROS] above the necrosis threshold level for tumors, while maintaining [ROS] in peritumoral tissues below that threshold, even when the tumor‐to‐peritumoral tissue ratio is as low as 2.

T Cell Exhaustion and Dendritic Cell‐Mediated Tertiary Lymphoid Structures (TLSs) Modulation Affect Response to Neoadjuvant Chemoradiotherapy in Microsatellite Stable Rectal Cancer

Advanced Science, EarlyView.
Using multi‐omics analysis, this study demonstrates that immune characteristics of the tumor microenvironment, rather than mutational profiles, are more strongly correlated with treatment response. Specifically, early exhausted T cells and tertiary lymphoid structures regulation by LAMP3⁺ dendritic cells emerge as key predictors of favorable outcomes ...
