Programmable Anisotropic Terahertz Permittivity via High‐Aspect‐Ratio 3D‐Printed Dielectric Mesh Networks

Advanced Optical Materials, Volume 14, Issue 34, 11 September 2026.
A 3D‐printed Terahertz (THz) anisotropic dielectric with programmable permittivity by varying infill density and creating high‐aspect‐ratio channels is presented. The proposed design was evaluated both experimentally, through THz time‐domain spectroscopy, and theoretically, through FDTD simulations and Effective Medium Theory analysis.

Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly

Advanced Science, Volume 13, Issue 49, 3 September 2026.
This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.

A 40.68‐MHz Active Rectifier Using PLL and PWM Control of DC‐DC Converter for ON/OFF Delay Compensation

International Journal of Circuit Theory and Applications, Volume 54, Issue 9, Page 4469-4481, September 2026.
A ramp‐based phase‐locked loop (RPLL) active rectifier operating at 40.68 MHz compensates switching delay variations to improve phase alignment. The proposed architecture achieves 90.3% peak power conversion efficiency and 98.0% voltage conversion ratio for high‐frequency wireless power transfer in implantable medical devices.

Single‐cell transcriptomic analysis reveals subtle fluctuations of oocyte cryopreservation on mouse early embryo development

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
Mature oocytes were subjected to cryopreservation followed by intracytoplasmic sperm injection (ICSI). Embryos at multiple developmental stages were collected, dissociated into single cells and processed for single‐cell library construction and bioinformatics analysis.
