The ultra-high-strength composite metal foam created by Afsaneh Rabiei is a highlight of a well-traveled career during which the researcher has tried to learn everything she can about advanced materials. The result: a brand new material that can save energy and lives. “Basically, it is a new material for all sorts of safety devices,” said Rabiei, associate professor of mechanical and aerospace engineering at North Carolina State University. Rabiei’s invention isn’t the first metal foam, but she says it’s the strongest. The main weakness of existing metal foams is the varying sizes of their cells — tiny pockets of space inside the material. Instead, Rabiei used cells of standard sizes and combined them with a metallic matrix to support the cell walls. That helps

And since the bulk steel is three times heavier than the steel foam, it’s easy to see how the foam could attract car manufacturers looking for a bumper that will improve safety and gas mileage. Rabiei sees plenty of uses for her invention, including in airplanes, boats, and structures that need impact protection with maintaining low weight. It’s this high strength-to-density ratio — defining a material that’s both strong and light — that makes Rabiei’s foam unique. “This material showed a much higher strength-to-density ratio than any metal foam that has ever been reported,” she said.

"Japanese Scientists invented "elastic water", paving the way for ecologically clean plastic materials Category: Science - Tags: ecology, Elastic Water, Jst, plastic, Tokyo University According to the Japan Science and Technology Agency (JST), Japanese Scientists invented "Elastic Water". Also made it to the news of Japan's National TV channel NHK, Japanese scientists from Tokyo University invented a new substance that consists of 95% water. Obtained by adding two grams of clay and a small quantity of some organic matter into normal water, this new substance is jelly-like and is considered proper for usage in medicine for the long-term to stick tissues together. The study period is scheduled to end in September 2010, if the scientists can succeed in increase the density of the substance, it can be used to produce ecologically clean plastic materials. A report has already been published in the latest issue of British scientific magazine "Nature". "
