Outperforming platinum with a metal-free fuel cell catalyst

By Damir Beciri
9 June 2013

korean-research-groupCollaboration between researchers in South Korea, Case Western Reserve University and University of North Texas resulted with a discovery of an inexpensive and easily produced catalyst that performs better than platinum in oxygen-reduction reactions. The finding is a step toward eliminating what industry regards as the largest obstacle to large-scale commercialization of fuel cell technology…. »

Researchers getting closer to artificial cartilage creation

By Damir Beciri
10 December 2011

knee-cartilage_0Researchers at the Case Western Reserve University are one step closer to create implantable replacement cartilage. The method allows cartilage to form from patient’s own stem cells without lengthy culture time before the implantation. The technology could solve cartilage problems which occur after sports injuries and accidents, as well as in cases of osteoarthritis which… »

One Comment3 September 2011

wind turbineA Case Western Reserve University researcher has built a prototype blade that is substantially lighter and more durable compared to materials currently used in blades of wind turbines. He came up with a polyurethane blade reinforced with carbon nanotubes, which make the material eight times tougher compared to other materials which are currently used as… »

26 July 2011

air-artificial-lungAn artificial lung built by researchers from Case Western Reserve University uses air instead pure oxygen which is required by current man-made lungs require. The researchers built the prototype device by following the natural lung’s design and tiny dimensions. Unfortunately, the commercial use of their invention is still years away, but the device is a… »

22 April 2011

ami-uv-self-healing-polymer-sceneA 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… »

Fish biomimicry used for bridge stability sensors during floods

By Damir Beciri
5 September 2010

salmonFloods cut down more bridges than fire, wind, earthquakes, deterioration, overloads and collisions combined, costing lives and hundreds of millions of dollars in damage. The speed and turbulence of an overflowing stream scours away the river bottom that provides the support for a bridge foundation. In order to counter that, researchers at the Case Western… »
