High‐Sensitivity Terahertz Gas Sensing Enabled by Undercut Metal‐Dielectric‐Metal Metamaterial

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 12, 23 June 2026.
A terahertz (THz) metamaterial gas sensor is demonstrated using a metal–dielectric–metal (MDM) absorber with an undercut dielectric layer, which enlarges the gas‐replaced volume and strengthens refractive‐index perturbation of the resonant mode. A reflection dip at 0.766 THz is observed, and acetone–nitrogen tests yield concentration‐dependent shifts ...

Optical Pulling Force on Gold Mie Particles via Germanium and Aluminum‐Based Structures

open access: yesAdvanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates a novel approach to generate optical pulling force on gold Mie objects of two different shapes and studies the effects for different object sizes, incident angles, and the aluminum tetrahedra separation. Using rectangular germanium blocks combined with aluminum tetrahedra, optical pulling force (OPF) is achieved over a broad ...

A Study on Enhancing Stability and Conductivity of ZnO Through Controlled Doping

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
First principles modelling reveals vanadium and indium as complementary tuning knobs in cubic ZnO, enabling controlled changes in optical absorption, dielectric screening, and frequency‐dependent conductivity. Moderate doping maximizes optoelectronic gain, while higher loading can trigger mechanical softening.

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.

Controlled Moderate Interfacial Reaction Facilitates High‐Strength Low‐Resistivity Barrier Layer for Half‐Heusler Thermoelectrics

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
The barrier layer is designed comprehensively by thermal expansion coefficient and interfacial reaction energy to yield a controlled interfacial reaction. Ultimately, the Co25Fe50Ni25/half‐Heusler joint simultaneously achieves low contact resistivity and high bonding strength.
