University of Pittsburgh (Pitt) researchers have found that self-moving gels can be used to enable the synthetic materials to “act alive” and mimic primitive biological communication. They managed to demonstrate that a synthetic system that can both emit and sense a chemical signal, and when the ability of chemical communication is combined with interaction with… »
Attempts to replace chromate coatings with non-toxic coatings have been underway since the 1980s. The awareness on effects of chromates was brought to the forefront in 1993 by the real-life incident involving Erin Brokovich and depicted in the movie released in 2000 of the same name. A research team at the University of Nevada, Reno… »
A team of experts in mechanics, materials science, and tissue engineering at Harvard School of Engineering and Applied Sciences (SEAS) have created an extremely stretchy and tough hydrogel which is a hybrid of two weak gels that combine to create something much stronger. This new gel can stretch up to 21 times of its original… »
University of California, San Diego bioengineers have developed a smart and easy-to-synthesize self-healing hydrogels that consist of linked chains of polymer molecules which are capable to self-heal in aqueous environment. This jello-like material’s ability to self-heal, bind in seconds and form a bond strong enough to withstand repeated stretching could find uses in biology, medicine,… »
Current electronic devices are becoming faster and denser, but such complex circuitry is prone to reliability problems, and once one tiny circuit within an integrated chip breaks, the whole chip or even whole device is unusable. A team of University of Illinois engineers has developed a self-healing system capable to repair a cracked circuit by… »
Swiss Federal Laboratories for Materials Science and Technology (Empa) researchers have been inspired by climbing plants to develop a polymer foam surface coating with a closed cell construction capable to reduce the pressure loss after the membrane is damaged. Aside making future inflatable structures more resistant, the technology could provide them with a longer operational… »
A team of researchers in the United States and Switzerland have developed a polymer-based material that can heal itself with the help of UV lighting. Metallo-supramolecular polymers are solid materials capable to become a supple liquid that fills crevasses and gaps left by scrapes and scratches once it is exposed to ultraviolet light for less than… »
Inspired by the hair-thin holdfast fibers that mussels secrete to stick against rocks, researchers from the University of Chicago managed to manufacture a synthetic version of the self-healing sticky substance used by mussels. The substance could be used as an adhesive or coating for underwater machinery or in biomedical settings as a surgical adhesive or… »
