As a thermal interface material, diamond/GaInSn composites have wide-ranging application prospects in the thermal management of chips. However, studies on systematic reliability that can guide the practical application of diamond/GaInSn in the high-temperature, high-temperature impact, or high-humidity service environments that are faced by chips remain lacking. In this study, the performance evolution of diamond/GaInSn was studied under high-temperature storage (150 °C), high- and low-temperature cycling (-50 °C to 125 °C), and high temperature and high humidity (85 °C and 85% humidity). The experimental results reveal the failure mechanism of semi-solid composites during high temperature oxidation. It is revealed that core oxidation is the key to the degradation of liquid metal composites' properties under high-temperature storage and high- and low-temperature cycling conditions. Under the conditions of high temperature and high humidity, the failure of Ga-based liquid metal and its composite materials is significant. Therefore, the material should avoid high-temperature and high-humidity environments.

Dry skin is a common condition that is experienced by many. Besides being particularly present during the cold season, various diseases exist all year round, leading to localized xerosis. To prevent it, the skin is provided with natural moisturizing factors (NMFs).

Although MEG is being developed as a green renewable energy technology, there remains significant room for improvement in self-sustained power supply, generation duration, and energy density. In this study, we present a self-sustained, high-performance MEG device with a bilayer structure. The lower hydrogel layer incorporates graphene oxide (GO) and carbon nanotubes (CNTs) as the active materials, whereas the upper aerogel layer is comprised of pyrrole-modified graphene oxide (PGO).

Rainy weather restricts the formation of high-quality Wuyi rock tea (WRT). Herein, an optimized withering process for rain-soaked leaves was developed using response surface methodology. Results showed that increasing the withering temperature, relative humidity, and withering time from 25 °C to 40 °C, 80 % to 97 %, and 3 to 6 h, respectively, effectively improved the sensory qualities of the optimized primary WRT (WRTO) prepared from rain-soaked leaves compared with those before optimization.

Background: Metabolic syndrome (MS) refers to a cluster of metabolic disorders characterized by systemic chronic inflammation. Er Miao San (EMS) is a classic traditional Chinese medicine compound containing Phellodendron amurense and Atractylodis rhizome at a ratio of 1:1, proven to be effective against inflammatory diseases in clinical practice. Nevertheless, the precise functions of EMS in treating MS and its underlying mechanism have yet to be elucidated.

One of the primary challenges in commercializing perovskite solar cells (PSCs) is achieving both high power conversion efficiency (PCE) and sufficient stability. We integrate wafer-scale continuous monolayer MoS buffers at the top and bottom of a perovskite layer through a transfer process. These films physically block ion migration of perovskite into carrier transport layers and chemically stabilize the formamidinium lead iodide phase through strong coordination interaction.
