Sympathetic laser-cooling of graphene with Casimir-Polder forces

open access: yes, 2016
We propose a scheme to actively cool the fundamental flexural (out-of-plane) mode of a graphene sheet via vacuum forces. Our setup consists in a cold atom cloud placed close to a graphene sheet at distances of a few micrometers.

Energy‐Efficient Fabrication of Biomimetic Materials for Sustainable Infrastructure Applications

open access: yesAdvanced Science, EarlyView.
Inspired by nacre's “brick‐and‐mortar” structure, this work develops an energy‐efficient approach that utilizes ice‐templating technology as the structure framework and carbon mineralization for rapid CaCO3 production, resulting in a strong yet tough carbon mineralized material (CMM) under mild conditions while also fixing CO2.

Unlocking the Interaction Mechanism of CNTs and C‐S‐H on Enhancing Elastic and Viscoelastic Properties of Alite Paste

open access: yesAdvanced Science, EarlyView.
This study explores carbon nanotubes’ (CNTs) role in enhancing alite paste’ elasticity and viscoelasticity. Experimental and simulation results reveal that CNTs weakly influence nucleation but significantly refine C‐S‐H gel structure and calcium hydroxide distribution.

Dual‐Graded Microstructure Engineering for Flexible Piezoresistive Sensors with High Sensitivity and Broad Linear Range in Physiological Monitoring

open access: yesAdvanced Science, EarlyView.
A flexible piezoresistive pressure sensor with dual‐graded microstructures achieves both high sensitivity (69.8 kPa⁻¹) and a broad linear range up to 300 kPa (R2 = 0.997). Synergizing structural deformation and tunneling conduction, it enables rapid, stable, and accurate detection of subtle physiological signals, offering a scalable and cost‐effective ...
