Automobile bumpers that deform and recover rather than crack and splinter, computer cases that withstand the occasional rough encounter, and resilient coatings that can withstand the ravages of the sun, may all be possible if tiny functionalized rubbery particles are imbedded in their plastic matrices, according to Penn State materials scientists.

“Plastics such as polypropylene, nylon, polycarbonate, epoxy resins and other compounds are brittle and fracture easily,” says Dr. T.C.

Renowned for their ability to walk up walls like miniature Spider-Men–or even to hang from the ceiling by one toe–the colorful lizards of the gecko family owe their wall-crawling prowess to their remarkable footpads. Each five-toed foot is covered with microscopic elastic hairs called setae, which are themselves split at the ends to form a forest of nanoscale fibers known as spatulas. So when a gecko steps on almost anything, these nano-hairs make such extremely close contact with the surface th

A discovery reported in the August 5 issue of Science could speed the design of materials that approach the hardness of diamond yet remain supple enough to be worked like metal.

In a massive computer simulation involving 128 computer processors and nearly 19 million atoms, materials scientist Izabela Szlufarska of the University of Wisconsin-Madison and colleagues at University of Southern California demonstrated the precise atomic mechanisms that explain why “nanostructured” cera

LINPAC’s new Zenit line of multi-layer stretch films is undergoing a name change and will, from now on, be called Zenium. Zenium stretch films, which were released earlier this year, are formulated to comply with new EU regulations concerning plastic materials that come into contact with food products.

High resistance to perforation and tearing and optimal flexibility are the major advantages of the Zenium line, which also offers excellent optical properties and increased anti-fogg

Student’s Testing Identifies Metal Mix with Superior Mechanical Properties

Using a high-tech but low-cost technique, a Johns Hopkins undergraduate has tested tiny samples of four metal alloys to find the best blend for use in platinum jewelry. After evaluating four metal mixtures, student researcher Christopher Kovalchick determined that platinum combined with a small amount of chromium in a cold-rolled and heat treatment process displayed the greatest strength.

Scientists at The University of Manchester have discovered a new class of materials which have previously only existed in science fiction films and books.

A team of British and Russian scientists led by Professor Geim have discovered a whole family of previously unknown materials, which are one atom thick and exhibit properties which scientists had never thought possible.

Not only are they ultra-thin, but depending on circumstances they can also be ultra-strong, highl
