Researchers at Oxford University’s Department of Materials have devised a new method of coating materials that are to be implanted into bone, resulting in encouraged bone in-growth and bonding while reducing the possibility of loosening implants.
Bone implants are desirable and/or essential in various medical procedures, and are often metallic and secured by an adhesive. Inert materials such as metals do not bond to the surrounding tissue and adhesives eventually degrade, allowing the implant to loosen and leading to the undesirable consequences of implant replacement.
Oxford researchers have addressed this weakness by developing a method of coating the implant so that bone in-growth is encouraged, the bonding is strengthened, and the possibility of loosening is greatly reduced. The coating consists of a phospholipid vesicle surrounded by a hydroxyapitite shell. These spheres are deposited in such a controlled manner in order to build a hierarchical pore structure that encourages bone in-growth.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
