Role of Energy‐Dependent Secondary Electron Emissions in Nonlinear Amplification of Plasma Density in Capacitive RF Discharge for Surface Processing

open access: yesPlasma Processes and Polymers, Volume 23, Issue 8, August 2026.
Energy‐dependent surface reactions become increasingly important as the applied voltage increases, leading to nonlinear amplification of plasma density in capacitively coupled Ar discharges. This amplification arises from coupled ion‐ and electron‐induced secondary electron emission, forming a feedback loop between the opposing electrodes.

Ultrathin Magnetic–Conductive Heterostructures for Absorption‐Dominant Electromagnetic Interference Shielding

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Synergistic Enhancement of Strength and Creep Resistance in Additive Manufacturing Ti‐6.5Al‐2Zr‐Mo‐V Alloy via In Situ Co‐Modification With Si and Y Elements

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The demand for advanced aerospace components necessitates near‐α titanium alloys with enhanced high‐temperature performance and compatibility with additive manufacturing (AM). To address this, an in situ alloying strategy was employed to co‐modify a Ti‐6.5Al‐2Zr‐Mo‐V alloy with Si and Y during laser powder bed fusion.

Control System for the Navigation of the Agricultural Robots: A Review

open access: yesJournal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...
