1613.使用数字全息技术对透明材料的特征测量
[非金属矿物制品业,信息传输、软件和信息技术服务业] [2015-07-24]
Digital holography is applied to measure the characteristics of transparent material. A digital hologram recording system to measure the surface of transparent material was established, and the digital holograms of transparent object were obtained in high quality. For postprocessing of hologram, the least-squares phase unwrapping algorithm was used in phase unwrapping, and the phase reconstruction image of transparent object was obtained. The information of material surfaces was measured and the characteristic was presented in 3D visualization. The validation experiment was conducted by NanoMap 500LS system; the results of validation experiment are well satisfied with the measurement by digital holography, which proved the feasibility of digital holographic technology as a good measurement tool for transparent material.

[非金属矿物制品业,医药制造业,科学研究和技术服务业] [2015-07-24]
Bioactive materials refer to a group of materials including composites, ceramics, and glasses that interact with biological systems and aid in repair and replacement of diseased tissue or bone. Bioactive glasses are an important category of bioactive materials that promote self-healing by interacting with body fluids and tissues without affecting the health and tissues of living organisms. They have a wide range of applications in surgical procedures, especially in tissue replacement and tissue repair. Bioactive glasses are composed of silicon, calcium, sodium, and phosphorus. They are widely used in orthopedics, followed by dentistry and cosmetic applications. They are commercially available in various forms such as powders, nano-powders, and granules.

1617.全球医疗陶瓷市场报告(2015-2019年)
[医药制造业,非金属矿物制品业] [2015-04-07]
Medical ceramics find extensive use in the Medical sector for a variety of applications, including treatment of cancer and related diseases, joint and hip reconstruction, and in the production of implantable electronic devices. These inorganic and non-metallic materials are also being used worldwide in various dental and orthopedic applications, and in the manufacture of surgical and diagnostic instruments. On the basis of material used, these ceramics can be classified into three: bioinert, bioactive, and bioresorbable. Bioinert ceramics such as aluminum oxide, zirconium oxide, silica oxides, and titanium oxide have been the most commonly used ceramics in the Medical sector. In recent years, however, manufacturers have been leaning toward bioactive ceramics such as bio-glass. Hydroxyapatite, a bioresorbable ceramic, has also been gaining popularity among market players in the last few years.
