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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
