Summary: A fabric with synchronous switching of color and wettability was prepared using ammonia as the switching link and myristic acid-modified titanium as the raw material. The color changes from colorfulness to colorless and the fabric changes from superhydrophobicity to superhydrophilicity within 10 seconds after encountering ammonia. This reversible wettability and synchronous blue-to-white color change provide new ideas for the preparation of materials with controllable wettability.

Summary: This paper demonstrates the rapid tunability of zinc superhydrophobic surfaces using femtosecond-laser-ablated microholes to control wettability. Surface energy of zinc can be increased by UV irradiation while surface energy of water can be decreased by heating water temperature to achieve quick photothermal wettability tuning. The potential application of the zinc superhydrophobic surfaces in micro-/nanofluidic devices is highlighted.

Summary: Cells have the ability to adapt to changing environmental conditions through regulatory networks. The Pho regulon in Saccharomyces cerevisiae is one such system that activates in low phosphate concentration to scavenge phosphate. However, the precise mechanism of this regulon was unclear until a systems analysis on single cells revealed an intermediate nuclear localization state of the transcriptional master regulator Pho4p. This finding explains the observed programmatic states of the regulon and improves our understanding of gene regulatory networks.

Summary: The Cu/AlN-Al2O3 nano-multilayer was deposited on 42CrMo4 steel samples using magnetron sputtering method, revealing that at high temperatures, Cu nanocrystals coarsen and migrate within the multilayer, even forming micron-sized reservoirs. As the temperature increases, cracks appear in the AlN-Al2O3 layers, causing Cu to be exposed on the surface of the NML.

Summary: Experimental studies have shown a strong positive effect of NaCl addition on the decomposition rate of chlorate in aqueous solutions. It is more reasonable in the chlor-alkali industry to first saturate the brine with sodium chloride and then eliminate chlorate by adding HCl to protect the electrolysis cell from chlorate ions.

Summary: In this paper, AlN-Al2O3 coatings with thicknesses ranging from 50 to 680 nm were deposited on a steel substrate by magnetron sputtering, and the phase inversion process of the steel/ceramic/copper configuration to the steel/copper/ceramic configuration was investigated. The results showed that the wettability of solid deoxidized steel by liquid copper is good, while the wettability of the ceramic by copper is poor. The flow of copper along the cracks in the ceramic depends on the thickness of the ceramic and can be enabled when the coating thickness is below a critical value. The stability of the steel/copper/ceramic configuration is further enhanced by gravity.

Summary: The goal of this research is to study the applicability of the diffusion boriding process to enhance the lifetime of steel selective soldering tools. Experimental results show that the double-phase iron-boride coating exhibits excellent resistance against the aggressive liquid solder alloy, which is the main reason for the failure of selective soldering tools made of steel. Thermodynamic calculations support the results of the dissolution tests.

Summary: This study investigates the thermal conductivity of two-phase WC-Co-Ni cemented carbides and its dependence on phase composition, temperature, and WC grain size. Through a combination of experiments and models, a reliable model for calculating the thermal conductivity of two-phase WC-Co-Ni is established and verified using experimental data. Furthermore, this model is used to predict the thermal conductivity of two-phase WC-Co-Ni under different phase-fractions, temperatures, and WC grain sizes, which can aid in designing cemented carbides with desired thermal conductivities.

Summary: This study aimed to measure the non-wetting to wetting transition temperatures of liquid tin on various steel surfaces in vacuum conditions. The experiment found that the contact angles of liquid tin on steel surfaces decreased with increasing temperature, with varying transition temperatures between low alloyed steels and high chromium steels. The formation of intermetallic compounds at the interface contributed to the relatively high contact angle values observed, which were different from metal/metal couples like liquid Cu on steel.
