Infrared and Terahertz Compatible Absorber Based on Multilayer Film

open access: yesFrontiers in Physics, 2021
In this paper, a similar Fabry-Perot cavity structure utilizing a multilayer film structure consisting of an ultrathin metal film is demonstrated for absorbing the infrared ray. This structure has low emissivity in the atmospheric window (3–5 and 8–14 μm)

Induced cosmological constant and other features of asymmetric brane embedding

open access: yes, 2009
We investigate the cosmological properties of an "induced gravity" brane scenario in the absence of mirror symmetry with respect to the brane. We find that brane evolution can proceed along one of four distinct branches. By contrast, when mirror symmetry

Low Infrared Emissivity and Strong Stealth of Ti-Based MXenes

open access: yesResearch, 2022
Advanced scenario-adaptable infrared (IR) stealth materials are crucial for creating localized closed thermal environments. Low emissivity over the broadest possible band is expected, as is superior mechanical deformability. Herein, we report a series of Ti-based MXenes with naturally low emissivity as ideal IR shielding materials.

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Emissivity measurement based on deep learning and surface roughness

open access: yesAIP Advances, 2021
Infrared stealth is an important guarantee for weapon equipment to survive on the battlefield. Emissivity is an important index to measure the infrared stealth characteristics, and the emissivity is closely related to the surface roughness of objects ...
