Strain‐Activated Mechanical Metamaterial With Programmable Dual‐Phase Stiffness and Enhanced Energy Absorption

Advanced Materials Technologies, Volume 11, Issue 19, 7 October 2026.
A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.

Carbon Dots With Concurrently Tunable Photoluminescence and Nanozyme Activity for Agricultural Stress Resistance: A Carbonization Degree‐Mediated Strategy

Aggregate, Volume 7, Issue 10, October 2026.
Carbonization degree is established as a unified structural parameter that synergistically governs the photoluminescence and SOD‐like activity of CDs. Progressive carbonization generates sp2‐conjugated domains where edge‐site carbonyl groups act as catalytic sites for SOD‐like activity.

Estimating Environmental RF‐EMF Exposure From Mobile Networks Using Signal Indicators Collected With the ETAIN 5G Scientist App

Bioelectromagnetics, Volume 47, Issue 7, October 2026.
ABSTRACT Smartphones track indicators of a reference signal to maintain network connectivity. These can serve as proxies for a subset of environmental radiofrequency electromagnetic field (RF‐EMF) exposure from mobile networks. In this multi‐country study, we developed conversion functions linking signal indicators collected with the ETAIN 5G‐Scientist

Laser‐Induced Graphene/AuNPs‐Gated OECT Biosensor for Sensitive Detection of PD‐L1‐Positive Exosomes Associated With Non‐Small Cell Lung Cancer

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lung cancer remains a major cause of cancer‐related mortality worldwide, and non‐small cell lung cancer (NSCLC) accounts for the largest proportion of diagnosed lung cancer cases. Exosomal programmed death‐ligand 1 (PD‐L1) has attracted increasing attention as a potential liquid‐biopsy biomarker associated with tumor immune regulation; however,

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

Small, Volume 22, Issue 56, 8 October 2026.
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.
