A Pitt and Carnegie Mellon team developed a new model of how self-repairing materials function and show that materials with a certain number of easily breakable bonds can absorb more stress, a natural trick found in the resilient abalone shell.
Researchers at Brown may have come across the right formula to deter bacterial migrants. The group reports two ways in which it modified the surface of titanium leg implants to promote skin cell growth, thereby creating a natural skin layer and sealing the gap where the device has been implanted into the body. The researchers also created a molecular chain to sprinkle skin-growing proteins on the implant to hasten skin growth.
Catalysts made of carbon nanotubes dipped in a polymer solution equal the energy output and otherwise outperform platinum catalysts in fuel cells, a team of Case Western Reserve University engineers has found.
Toyohashi Tech researchers develop an innovative infrared photodetector exploiting 'plasmon resonance' at the surface of gold nanorods, which enhances the density of photoelectrons excited over the Schottky barrier. This technology shows potential as the basis for the development of high efficiency infra-red photodetectors for optical communications systems.
Researchers at the University of Cambridge use the example of the conch shell as illustration of toughness-by-architecture in the quest for new synthetic materials for engineering, construction and aerospace applications.
Small artificial tubes in the veins, so-called stents, dilate the veins and allow the blood to circulate again without hindrance. But after a while, the deposit of cells and blood components starts at these tubes, as well, and thus the blood vessel narrows again. In an international joint project, scientists are now investigating the feasibility, how to change the surface of these tubes so that no unwanted components may no longer be deposited there.
nano tech 2011 International Nanotechnology Exhibition and Conference celebrated its 10th annual event from Feb. 16 to Feb. 18, 2011 in Tokyo. 638 exhibitors covering an exhibition surface of 6786 square meters presented their nano technologies and products at this world's largest nano technology fair.
The intention of the compendium is to bring together researchers, create synergy in their work, and establish links and communication between them mainly during the actual research phase before publication of results.
The Materials Research Division at Riso DTU has received a grant from the Danish Council for Strategic Research to develop the scientific basis and computational tools for the microstructural optimization of materials for wind blades.
A new 'templated growth' technique for fabricating nanoribbons of epitaxial graphene has produced structures just 15 to 40 nanometers wide that conduct current with almost no resistance. These structures could address the challenge of connecting graphene devices made with conventional architectures - and set the stage for a new generation of devices that take advantage of the quantum properties of electrons.
Engineers at Ohio State University have invented a lens that enables microscopic objects to be seen from nine different angles at once to create a 3D image. Other 3D microscopes use multiple lenses or cameras that move around an object; the new lens is the first single, stationary lens to create microscopic 3D images by itself.
