High Manganese Steel Alloying Process and Its Influence on Microstructure and Properties of the Steel

引用

Journal of Materials Science & Technology 1995年第2期11卷 102-108页

The influence of two kinds of alloying processes, adding Nb (or Ti) and N-Mn alloy as well as adding Nb (or Ti) and spraying Nz, on microstructures and properties of a high manganese steel has been studied. It has been found that adding Nb(or Ti), accompanying with N-Mn alloy, is unfavourable to microstructure compactness of the high manganese steel, but adding Nb (or Ti) and spraying N-2 into the melt is good for refining austenitic grain, forming a lot of hard particles and improving microstructure compactness. The mechanical properties of the high manganese steel have relation to the content of elements Nb or Ti. Its fracture mode will turn ductile fracture into brittle cleavage fracture gradually By X-ray and TEM analysis, it is proved that the austenite can be transformed to deformation-induced cr martensite after adding a certain amount of element Nb (or Ti). The microstructure transformation of alloying high manganese steels through deformation is one of methods for strengthening austenite matrix acid increasing the work-hardening rate as well as improving antiwear property.

Development of a Peristaltic Micropump for Bio-Medical Applications Based on Mini LIPCA

引用

Journal of Bionic Engineering 2008年第2期5卷 135-141页

作者： Thanh Tung Nguyen my Pham Nam Seo Goo Department of Aerospace Engineering Konkuk University Department of Advanced Technology Fusion Konkuk University

This paper presents the design, fabrication, and experimental characterization of a peristaltic micropump. The micropump is composed of two layers fabricated from Polydimethylsiloxane （PDMS） material. The first layer has a rectangular channel and two valve seals. Three rectangular mini lightweight piezo-composite actuators are integrated in the second layer, and used as actuation parts. Two layers are bonded, and covered by two Polymethyl Methacrylate （PMMA） plates, which help increase the stiffness of the micropump. A maximum flow rate of 900μ*** 1 and a maximum backpressure of 1.8 kPa are recorded when water is used as pump liquid. We measured the power consumption of the micropump. The micropump is found to be a promising candidate for bio-medical application due to its bio-compatibility, portability, bidirectionality, and simple effective design.

背景:肝脏类器官对阐明肝脏疾病的确切病理机制及对肝脏疾病的治疗具有重要的意义。目的:总结目前国内外该领域的基础研究,回顾以往肝脏类器官的构建、疾病建模和移植治疗的重要研究进展,探讨肝脏类器官联合组织工程技术的应用前景。方法:检索PubMed数据库及中国知网数据库收录的相关文献,英文检索词为“liver,organoids,liver diseases”,中文检索词为“肝,类器官,肝脏疾病”,主要检索时限为2018年4月至2024年4月,通过人工阅读排除重复文献等,最终纳入94篇文献进行归纳分析。结果与结论:①肝脏类器官构建的种子细胞主要集中于成体细胞和多能干细胞,通过辅助各种细胞因子参与信号引导作用和细胞外基质提供3D微环境,促进类器官的产生,但是整体成熟度不高,有望通过结合组织工程技术改善这一问题;②体外疾病建模方面主要在简单疾病和单基因遗传病领域研究较多,类器官高度保留患者遗传特性,有望通过结合CRISPR-Cas9基因矫正和其他新兴技术模拟更复杂的肝脏疾病并阐明更深层次的病理机制;③体内移植治疗方面,肝脏类器官能够安全有效的植入,表现出惊人的肝功能替代潜力及组织再生能力,并且还可能通过与其他组织工程材料结合达到治疗目的。
