Robust Superamphiphobic Coatings Based on Raspberry-like Hollow SnO Composites.

Good mechanical and chemical stabilities are the key factors for the wide application of superhydrophobic surfaces. In this work, we first prepared raspberry-like hollow structured SnO nanoparticles using a simple hydrothermal method, followed by an annealing step. Then, the intrinsic raspberry-like hollow SnO nanoparticles were combined with hydrophilic SiO nanoparticles to construct rough surfaces with suitable hierarchical structures, and 1,1,2,2-perfluorodecyltriethoxysilane (FAS-17) was used as a hydrophobic modifier of SnO, while epoxy resin was used as an adhesive to prepare a superamphiphobic coating with good stability and durability.

Maternal health care wearing equipment based on fetal information monitoring.

In order to monitor the fetal information in real time and ensure the health of the pregnant women themselves and their fetuses during pregnancy, a kind of health wearing equipment, abdominal care belt is designed in this study, which can be worn by pregnant women and can be monitored by modern mobile medical APP, and verifies the related performance of the design through a series of experiments. The results show that the safety, practicability and aesthetics of the abdominal care belt designed in this study are all up to the standard. Therefore, the abdominal care belt designed in this study is a relatively successful product, which is expected to be applied in the future and enter the market, so that pregnant women during pregnancy can be more relaxed and convenient.

Durable Self-Cleaning Surfaces with Superhydrophobic and Highly Oleophobic Properties.

Functional surfaces with superhydrophobic and superoleophobic properties are of great interest in many applications. However, such surfaces are generally difficult to obtain. Although a few superamphiphobic surfaces have been developed recently, a challenge still remains in preparing such a surface with good durability which is a critical issue in practical application.

[The comparison of the micro-syringe with clinical usage].

Micro-syringe as a result of the high frequency of clinical use, direct contact with patients, the failure of its equipment will have a direct impact on the patient's disease status. Researchers in this paper, by simulating the test fluid, electrical safety testing and analysis of statistical methods such as maintenance records, consider six kinds of common injection pump, in terms of performance, safety and the failure rate of three performance. Compared the performance analysis, summarized the various types of injection pump characteristics, researchers make suggestions to clinical departments, equipment procurement and equipment management departments for usage and improvement.
