A new genre of plastics that mimic the human skin's ability to heal scratches and cuts offers the promise of endowing cell phones, laptops, cars and other products with self-repairing surfaces, scientists reported today. The team's lead researcher described the plastics, which change color to warn of wounds and heal themselves when exposed to light, here today at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society....

Smart, Self-healing Hydrogels Have Possibilities In Medicine, Engineering

[ Watch the Video ] University of California, San Diego bioengineers have developed a self-healing hydrogel that binds in seconds, as easily as Velcro, and forms a bond strong enough to withstand repeated stretching. The material has numerous potential applications, including medical sutures, targeted drug delivery, industrial sealants and self-healing plastics, a team of UC San Diego Jacobs School of Engineering researchers reported March 5 in the online Early Edition of the Proceedings...

When one tiny circuit within an integrated chip cracks or fails, the whole chip — or even the whole device — is a loss. But what if it could fix itself, and fix itself so fast that the user never knew there was a problem? A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Led by aerospace engineering professor Scott White and materials science and...

Michael Kessler has worked with polymers that repair themselves when they crack. And he's worked with polymers made from vegetable oils. Now he's working to combine the two technologies. Kessler, an Iowa State University associate professor of materials science and engineering and an associate of the U.S. Department of Energy's Ames Laboratory, is researching and developing biorenewable polymers capable of healing themselves as they degrade and crack. "If successful, the results of this...

Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new microcapsules burst when exposed to light, releasing their contents in ways that could have wide-ranging commercial uses from home and personal care to medicine. Their study appears in the Journal of the American Chemical Society, a weekly publication. Jean Fr©chet, Alex Zettl and colleagues...

Adding a food additive to damaged polymers can help restore them to full strength, say scientists at the University of Illinois who cooked up the novel, self-healing system. The repair process, in which solvent-filled microcapsules embedded in an epoxy matrix rupture when a crack forms, is a major improvement over the original self-healing process first described in February 2001. "While our previous solvent worked well for healing, it was also toxic," said Scott White, a professor of...

Will the day come when cracks in buildings close up without external help and before they get to the stage where they cause damage to the component? This might appear utopia, but it already occurs in nature. When a person suffers a minor wound, the human body reacts to close the opening, sending the blood platelets needed to the affected area "“ and with no need in many cases for any external coagulant substance to be employed.This reaction of nature to damage suffered was the starting...


Word of the Day
tessitura
  • The prevailing range of a vocal or instrumental part, within which most of the tones lie.
This word is Italian in origin and comes from the Latin 'textura,' web, structure.
