Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates the use of 2D materials drum resonators to generate and modulate radio‐over‐laser signals. Taking advantage of the self‐sustained oscillations arising in cavity optomechanical systems by a continuous wave visible laser, a radio frequency signal is generated and frequency‐modulated by just changing a DC gate voltage.

Atomic‐Level Insight of Carbon‐Based Anodes for Advanced Sodium Storage: Electrochemical Mechanisms and Molecular Simulation‐Assisted Modification

cMat, Volume 3, Issue 2, June 2026.
Hard carbon is a promising anode for sodium‐ion batteries, yet its Na+ storage mechanism remains elusive. This review summarizes Na+ storage behavior in hard carbon from first‐principles (DFT) calculations, establishes structure–function relationships, summarizes DFT‐based evaluation methods, and provides perspectives for the rational theoretical ...

A Trust‐Based Random Forest Approach for Detecting Blackhole Attacks in Vehicular Ad Hoc Networks

Engineering Reports, Volume 8, Issue 6, June 2026.
A multi‐metric trust framework combined with Random Forest learning detects and mitigates blackhole attacks in VANETs. By dynamically isolating malicious vehicles, the model sustains high packet delivery, low latency, and accurate intrusion detection under severe attack conditions.

Multi‐Source Adaptive‐Fusion Transfer Learning for Streamflow Forecasting in Data‐Scarce Catchments

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Streamflow gauging records remain sparse in many regions, limiting hydrological predictions. Transfer Learning (TL), which uses knowledge from data‐rich sources to improve predictions in data‐scarce targets, has emerged as a promising solution.
