Finding an economical way to make a polyester commonly found in many types of bacteria into a plastic with uses ranging from packaging to biomedical devices is a long-held scientific goal. Such a polymer would be a “green” plastic, in that it would be biodegradable.
Geoffrey Coates, a professor of chemistry and chemical biology at Cornell University, Ithaca, N.Y., has partially achieved this goal by discovering a highly efficient chemical route for the synthesis of the polymer, known as po
How do you improve on plastic, a modern material that has already changed the way we do everything from design medical devices to build cars? Embed it with specialized proteins called enzymes, says Shekhar Garde, assistant professor of chemical engineering at Rensselaer Polytechnic Institute.
“Such protein-enhanced plastics might someday be able to act as ultra-hygienic surfaces or sensors to detect the presence of various chemicals,” says Garde. These types of materials could have a wide
Discovery could lead to new therapies for Smith-Magenis Syndrome
Researchers at Michigan State University have identified the gene responsible for a developmental disorder known as Smith-Magenis syndrome (SMS), a discovery that could lead to new therapies for the disorder and the myriad problems that accompany it.
The finding is documented in the March 24 issue of Nature Genetics, a prestigious peer-reviewed British journal.
SMS is a chromosome microdeletion syndrome th
Because methanol, as a liquid, would be easier to dispense using current infrastructure, it will likely be one of the first fuels for fuel cells.
Speaking at the 225th national meeting of the American Chemical Society March 23-27 in New Orleans, Yu Seung Kim, a former research scientist at Virginia Tech, will report the results of studies at Virginia Tech to determine the optimum materials for use as a proton exchange membrane in a methanol-based fuel cell.
Methanol is the
Telecoms systems contain an awkward mixture of optics and electronics. A purely optical system would permit the very high data rates needed by the Internet, but at the moment the switching and routing, as well as the “last mile” to the customer, still depend on slower electronic components. Speaking at the Institute of Physics Congress on Monday 24 March, Professor Robert Denning from Oxford University will explain how his novel holographic approach to making 3-dimensional photonics crystals could al
Sascha Abramson has been investigating new methods to ensure that polymer medical implants in the human body don’t fail. Abramson looked at degradable polymers, ones the body can ultimately absorb, to gain a deeper understanding of how and why their structures change – crucial parts of a puzzle that must be solved for polymers to perform predictably and successfully in medical implants.
Her research was conducted as a postdoctoral associate at Rutgers’ New Jersey Center for Biomaterials in
