Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

Advanced Functional Materials, EarlyView.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

Advanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

Reappraisal of telesurgery in the era of high‐speed, high‐bandwidth, secure communications: Evaluation of surgical performance in local and remote environments

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 167-174, January 2023., 2023
This study aims to examine the feasibility of telerobotic surgery by validating the communication environment and local/remote robot operation. The performance of remote surgery over a commercial line was equivalent to that of the local environment. Therefore, remote surgery using a commercial line can be performed safely, indicating that we have the ...

High-Efficiency All-Dielectric Metasurfaces for Ultra-Compact Beam Manipulation in Transmission Mode [PDF]

, 2015
Metasurfaces are two-dimensional optical structures enabling complete control of the amplitude, phase, and polarization of light. Unlike plasmonic metasurfaces, planar silicon structures facilitate high transmission, low losses and compatibility with existing semiconductor technologies.
