Abstract An ideal radiative cooler requires accurate spectral control capability to achieve efficient thermal emission in the atmospheric transparency window (8–13 μm), low solar absorption, good stability, scalability, and a simple structure for effective diurnal cooling. Flexible cooling films made from polymer relying on intrinsic absorbance represent cost-effective solution but lack accuracy control. Here, we propose demonstrate metasurface concept enabled by periodically arranged...
Ti 3 C 2 , one of the most studied MXenes (M is an early transition metal, and X either or N), has attracted considerable attention due to their excellent electrical conductivity, hydrophilicity, catalytic activity. To date, are prepared from powders chemical etching under conditions long duration (generally ≥8 h) high temperature ≥35°C). In this study, with –F –O/–OH terminal groups was successfully obtained by electrochemically porous AlC sheet electrodes in NH 4 HF solution at room...
The phenomenon of coupled flow between free and porous media is characteristic fluid flowing across media, but the slip characteristics at coupling interface need to be further studied. purpose this work investigate velocity distribution turbulence with a high Reynolds number above in media.

Effective Thermal Conductivity (ETC) prediction of sintered lunar regolith plays a crucial role in developing extraterrestrial thermal processing and construction techniques for In-situ Resource Utilization (ISRU) projects on the Moon. Most existing literature has been focused packed without considering sintering mechanism. Herein, we presented mechanistic model to estimate ETC regolith. The Monte-Carlo method was applied simulate neck resistance between multi-scaled particles, while...
Electrochemical discharge machining (ECDM) is one effective way to fabricate non-conductive materials, such as quartz glass and ceramics.
