Summary: This paper proposes a Pt-Al2O3 composite nano-thick interdigital electrode (IDEs) for high-temperature SAW sensors. The IDEs have good structural stability and low impurity concentration at high temperatures. Improved quality factors and matched electrical impedance can be achieved through electroacoustic optimization. Multiple SAW temperature sensors using the composite IDEs also perform well at higher temperatures.

Summary: In this study, hydrogen and methane were used as reactive gases for growing single-layer graphene on a copper foil substrate using chemical vapor deposition. The graphene was then transferred to a silicon substrate for the growth of nano zinc oxide. The characteristics of CVD-deposited graphene and the nano zinc oxide were analyzed using various instruments. The graphene/zinc oxide nano-heterostructure sensor showed high sensitivity and repeatability in detecting hydrogen gas due to the specific surface area and oxygen vacancy defects of the zinc oxide nanostructure, as well as the P-N heterojunction formed between zinc oxide and graphene.

Summary: Porous Pt-based nanomaterials with abundant active sites and accessible surfaces have significant potential for various applications, with pore size being a key factor in determining their specific usage. While Pt-based nanomaterials with mesopores and macropores have been extensively studied, there are limited effective methods for preparing Pt-based nanomaterials with high-density micropores. In this work, a simple method of chemical etching using intermetallic PtPb networks (NWs) as starting material was used to prepare high-density microporous Pt-Pb NWs, introducing a large amount of micropores and defects into the NWs.

Summary: Fiber length is a crucial property in textile processing, with the HVI being a commonly used tool to assess cotton fiber properties. Two important parameters, UHML and UI, are used to describe fiber length and uniformity. The fibrogram provides more descriptive information than HVI, but limited research has been done on its stability and repeatability.

Summary: With the increasing appearance and expansion of high-strength hydrogels in various emerging fields, such as industry, medicine, and green development, there have been significant developments and achievements in the synthesis and application of high-strength hydrogels in terms of raw materials, preparation methods, and reinforcement mechanisms. However, there is a lack of systematic reviews on high-strength hydrogels. This article discusses the advantages of natural and synthetic materials, characteristics of high-strength hydrogels prepared from different raw materials, and the influence of physical interactions or chemical bonds on the strength of hydrogels. It also systematically explains various strengthening strategies and their mechanisms, and proposes possible future directions for the development of high-strength hydrogels based on application requirements and existing drawbacks.
