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.

Flexible metal-organic frameworks (MOFs) have emerged as a new generation of porous materials and are considered for various applications such as sensing, water or gas capture, and water purification. MIL-88 A (Fe) is one of the earliest and most researched flexible MOFs, but to date, there is a lack in the structural aspects that govern its dynamic behaviour. Here, we report the first crystal structure of DMF-solvated MIL-88 A and investigate the impact of real structure effects on the dynamic behaviour of MIL-88 A (Fe), particularly upon water adsorption.

Contactless human-machine interfaces (C-HMIs) are revolutionizing artificial intelligence (AI)-driven domains, yet face application limitations due to narrow sensing ranges, environmental fragility, and structural rigidity. To address these obstacles, we developed a flexible photonic C-HMI (Flex-PCI) using flexible visible-blind near-infrared organic photodetectors. In addition to its unprecedented performance across key metrics, including broad detection range (0.

Background And Aim: Rising global temperatures and increasing humidity levels are intensifying the risk of heat stress (HS) in high-yielding dairy cattle. The temperature-humidity index (THI) is a standard metric for evaluating thermal stress in livestock. This study aimed to assess seasonal and diurnal variations in temperature, relative humidity, and THI within a milking parlor and determine their compliance with established thermal comfort thresholds for dairy cows.

Single-component white-light-emitters ensure color stability while reducing device complexity, and are ideal candidates for white light-emitting diodes (WLEDs). However, the realization of single-component white-light emission with high efficiency and stability is still a challenge. Herein, a supramolecular cation strategy was used to synthesize the organic-inorganic hybrid copper(I) halide [(AMTA)(18C6)]CuI (1), with AMTA = 1-adamantanamine and 18C6 = 18-crown-6.

Per- and polyfluoroalkyl substances (PFAS) are man-made pollutants widely used in industrial and consumer products, known to pose significant health risks. While their occurrence in water, soil, and food has been extensively studied, limited research has focused on ambient air, particularly in the U.S.
