Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

open access: yesAdvanced Physics Research, Volume 5, Issue 7, July 2026.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Defects‐Triggered In Situ Reconstruction in Metal‐Halide Perovskites for Photo‐Rechargeable Lithium‐Ion Batteries

open access: yesInterdisciplinary Materials, Volume 5, Issue 4, Page 670-682, July 2026.
This work presents a strategy for the in situ formation of heterostructures in bifunctional photoelectrodes for photo‐rechargeable lithium‐ion batteries (PRLIBs). Defect‐driven reconstruction in metal‐halide perovskites (MHP) activates Cu+/Cu2+ leaching from the current collector, thereby enabling the in situ formation of CuO/CuI‐MHP heterojunctions ...

PEC‐DFM Hybrid‐Sensor Based on Nanoparticle‐Resolved Estimation for Sensitive and Reversible Glucose Monitoring

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
Abstract The accurate detection of glucose in wound exudate is critically important for monitoring chronic wound healing. While photoelectrochemical (PEC) sensors are widely used, they often suffer from material degradation caused by redox reactions during operation. Herein, we introduce a dark‐field microscopy (DFM) setup integrated with a PEC system,
