Hyperbranched polymers – tree-like molecules – are not particularly useful for the creation of plastic films and molded parts because they dont entangle. So Virginia Tech researchers have created segmented hyperbranched plastics, which do entangle and result in high-performance polymers.
Virginia Tech chemistry professor Timothy E. Long of Blacksburg will describe the configuration and functionality of the new family of polymers at the 227th Annual Meeting of the American Chemical Society, being held in Anaheim, Calif., March 28 through April 1, 2004.
"We have placed extended sequences between the branch points," said Long. "Think of elastic springs. If a trees branches were on springs, they would more easily diffuse and entangle."

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
