Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents

Small, EarlyView.
Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 594-606, September/October 2026.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency ( > 500 ms) and inadequate coverage at high latitudes,

E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure

Advanced Materials, Volume 38, Issue 43, 3 August 2026.
The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...

An Optically Transparent, Lightweight, High‐Efficiency, and Ultra‐Broadband Polarization Converter Based on a Low‐Filling‐Factor Metallic Frame Metasurface

Advanced Theory and Simulations, Volume 9, Issue 8, August 2026.
The graphical abstract presents the unit‐cell architecture of the proposed transparent metasurface polarization converter, featuring a low‐filling‐factor rotated copper frame on PET, an air‐cavity spacer, and an ITO ground plane. The design enables optical transparency, lightweight construction, and ultra‐broadband, high‐efficiency cross‐polarization ...

Self‑Protective Carbonized Polymer Dots Enabling Ultralong Room‑Temperature Phosphorescence in Strong and Tough Flexible Gels

Aggregate, Volume 7, Issue 8, August 2026.
The trade‐off between intersystem crossing and triplet exciton stabilization in PVA‐based self‐protective CPDs is resolved by tuning the alcoholysis degree of PVA. Using PVA with 88% alcoholysis affords NCD88 with an ultralong RTP lifetime of 1.05 s.

Harnessing edge computing and citizen science: A new prototype design for continental‐scale acoustic monitoring in Australia and beyond

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2295-2308, August 2026.
Abstract Inadequate monitoring of biodiversity is a characteristic of conservation the world over. The potential of acoustic monitoring is compelling, although the challenges remain substantial. Effective solutions require transdisciplinary collaboration among stakeholders, a focus on open‐source development, and flexible, multipronged technical ...

A Dendrite‐Resistant Sodium/Porous‐Carbon Anode for Solid‐State Batteries: Strategies and Challenges for Low‐Pressure Operation

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Sodiophilic mesoporous carbon confers a near‐perfect interface between Na metal and ceramic solid electrolytes, while serving as a host for solid Na anodes. This synergy forms a foundational element for sodium solid‐state batteries (Na‐SSBs) in pairing a dendrite‐resistant anode with an inherently (electro)chemically stable ceramic electrolyte.
