工程化学

Tissue engineering is a multidisciplinary science merging with cell biology, material science, engineering and chemistry. Its basic idea is to expand a number of cells in vitro and seed them on a polysynthetic biodegradable polymer structure, and finally enable the organization of 3-dimmentional and functional tissues or organs.

组织工程技术是融合了细胞生物学、材料科学、工程学和化学的一门边缘学科，它的基本思想是用少量组织细胞经体外培养扩增后播种在可降解的生物支架材料上，再回植入体内形成有功能的组织或器官。

As MEMS (Micro Electro-Mechanical Systems) technology progresses rapidly, the synergism between MEMS and biomedical technology becomes closer than ever before. When the uTAS was introduced in the last two decades, many microfluidic chips, microelectrodes, and microreactors are being studied for drug detection, environment detection, gene analysis etc. Due to its small volume, low pollution, low consumable and good portability, uTAS plays a very important role in biomedical, biochemical, environment engineering fields.

随着MEMS(Micro Electro-Mechanical System，微机电系统)制造技术的不断发展，生物医学与其之间的联系越来越紧密，自上世纪90年代初提出uTAS(Micro Total Analysis System，微全分析系统)之后，各种各样的微流控芯片、微反应器、微电极、微分离器等便大量涌现，广泛应用于药物检测、环境监测、基因分析等诸多领域中，并且由于其试剂消耗量少、检测效率高、环境污染小、体积小、易于携带等优点，在生物医学、化学、环境工程等领域受到越来越多的重视。

Mondell engineering stone is high-technical decorating surface which is isomerized and polymerized from picked natural rimed stone ( the conpozation of Sio2 is over 99.99 percent). The stone is glittering, hard. It is not easy to fade or change the shape. It is not radiant and acid-fast. It is antibacterial and clean. It has good physical and chemic performance. This series is wildly used for its beautiful decoration in walls, floor, platform and so on. It combines features of natural stone and PMMA solid surface to get the rich and glittery colour.

蒙代尔工程石是采用精选的天然石结晶矿产为原料（石英砂Sio2的含量达到99.99%以上），在全自动生产线的高温高压状态下异构聚合而成的高科技装饰面材，具有晶莹剔透、硬度高、不变形、不退色、无辐射性、耐酸碱、易清洁、抗菌、卫生等优异的物理性能及化学性能，应用空间相当广泛，可应用于地面、外墙、台面等装饰自然美：真正的石材质感、兼顾天然石和亚克力人造石二者之优点，色彩丰富、晶莹剔透。
