Surgeons battle time and the body’s defenses as they stitch together veins and arteries, whether after an injury or in the course of such treatments as transplants or bypasses. Loss of blood before a site is closed and too much clotting soon after challenge medical care.
Virginia Tech researchers are creating biocompatible adhesives for use with vascular tissue that will speed the process of mending tissue. They will present the research at the 227th annual meeting of the American Chemical Society in Anaheim, Calif., March 28 through April 1, 2004.
The goal is to make it possible for surgeons to splice, reattach, or mend vascular tissue by applying a biopolymer coating and activating it with light, such as a laser, explains Timothy Long of Blacksburg, professor of chemistry in the College of Science at Virginia Tech. Another use would be as a stable, easy-to-use material that medics could apply to stop bleeding and prevent clotting.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
