The Taiwan Warm Current Deep Water (or the East China Sea Upper Layer Water, or the East China Sea Subsurface Water) lying in the deep and bottom layers off the coast of Fujian-Zhejiang is one of the main watermasses in the continental shelf region of the western East China Sea. The hydrographical conditions and the fishery productions in this region are affected remarkably by the decline and growth of the Taiwan Warm Current Deep *** the temperature, salinity and origin of the Taiwan Warm Current Deep Water have been investigated by oceanographers the world over, there are up to now few papers published on its characteristics of variations (seasonal and multiyear variations). Understanding of this problem will be helpful to further characterize this watermass. For this reason, in this paper, section 28°N representing the middle Taiwan Warm Current Deep Water and section 30°N representing the northern Taiwan Warm Current Deep Water are taken for examples, and the method of similar coefficie

通过凝结时间、水化温度、XRD、SEM、抗压强度试验等研究了纳米C-S-H早强剂对水泥水化及混凝土强度的影响,并分析了作用机理。结果表明:纳米C-S-H早强剂明显缩短了水泥的凝结时间;随着纳米C-S-H早强剂掺量的增加,水化温度峰出现时间缩短,且峰值提高;掺入适量的纳米C-S-H早强剂不改变水泥的水化产物种类,但加速了水泥水化进程,提高了混凝土的早期抗压强度,且后期(28 d、56 d)抗压强度无倒缩。

Periodontitis is indeed a chronic inflammatory disease caused by microorganisms, and it is a leading cause of tooth loss in adults worldwide [1–3]. The immune system typically maintains a balance with pathogenic bacteria in the body, and the local mucosal immune system effectively monitors and controls these microorganisms to prevent excessive inflammation.

With the use of historical data from their 1982-1985 special observation at the source area of the Taiwan Warm Current the authors conducted studies to clarify the temperature and salinity characteristics, variability, and origin of the Taiwan warm Current Water, and its influence on the expanding direction of the Changjiang Diluted *** main results are given below.（1）The Taiwan Warm Current Water can be divided into the 'Surface Water of the Taiwan Warm Current' formed due to the mixing of the Kuroshio Surface Water flowing northward along the east coast of Taiwan with the Taiwan Strait Water, and the 'Deep Water of the Taiwan Warm Current' originated from Kuroshio Subsurface Water to the east of Taiwan. It is characterized by stable low temperature and stable high salinity in summer. The maximum seasonal variation and maximum secular variation of temperature and salinity are 1.87℃, 0.26‰ and 2.96℃, 0.37‰, respectively.（2）The variation in strength of the Taiwan Warm Current is the main influe

Leather for flexible multifunctional bio-based materials: a review

引用

Journal of Leather Science and Engineering 2022年第1期4卷 225-240页

作者： Zhongxue Bai xuechuan wang Manhui Zheng Ouyang Yue Long Xie Siyu Zha Shuyin Dong Tong Li Yanyan Song Mengchen Huang Xinhua Liu College of Bioresources Chemical and Materials Engineering Shaanxi University of Science and TechnologyXi’an 710021China College of Chemistry and Chemical Engineering Shaanxi University of Science and TechnologyXi’an 710021ShaanxiChina Institute of Biomass and Functional Materials Shaanxi University of Science and TechnologyXi’an 710021China.

Nowadays, diverse leather usage conditions and increasing demands from consumers challenge the leather industry. Traditional leather manufacturing is facing long-term challenges, including low-value threshold, confined applica-tion fields, and environmental issues. Leather inherits all the biomimetic properties of natural skin such as flexibility, sanitation, cold resistance, biocompatibility, biodegradability, and other cross-domain functions, achieving unre-mitting attention in multi-functional bio-based materials. Series of researches have been devoted to creating and developing leather-based flexible multi-functional bio-materials, including antibacterial leather, conductive leather, flame-retardant leather, self-cleaning leather, aromatic leather, and electromagnetic shielding leather. In this review, we provide a comprehensive overview of the commonly used leather-based functional materials. Furthermore, the possible challenges for the development of functional leathers are proposed, and expected development directions of leather-based functional materials are discussed. This review may promote and inspire the emerging preparation and applications of leather for flexible functional bio-based materials.
