The electrode diameter is 30 µm and the inter electrode distance is 200 µm (b) A fluorescent microscope image of the cluster in (a), stained for cell nuclei (DAPI-blue), glia (GFAP-green) and neurons …
Biomicrofluidics – Embryonic stem cell bioprinting for uniform and controlled size embryoid body formation Two main goals of bio-inkjet printers is to grow new body parts for organ transplants or tissues for making regenerative medicine repairs. Making body parts, organs or tissues begin with a printed mass of embryonic stem cells. Getting the embroid body …
Photograph of a thin, flexible metallic glass fiber (left) and an electron microscopy image of a metallic glass rope weaved from such fibers (right). Nature Asia Pacific Materials – Glassy metallic wires can be controllably manufactured by drawing from a supercooled rod The metals we are most familiar with adopt a periodic, crystalline atomic arrangement. …
1. On May 3, the Department of Energy (DOE) dedicated the Consortium for Advanced Simulation of Light Water Reactors (CASL), an advanced research facility that will accelerate the advancement of nuclear reactor technology. CASL researchers are using supercomputers to study the performance of light water reactors and to develop modeling that will help accelerate upgrades …
An artistic rendering of the suspension as it freezes shows graphite flakes clumping together to form a connected network (dark spiky shapes at center), as they are pushed into place by the crystals that form as the liquid hexadecane surrounding them begins to freeze. Image: Jonathan Tong A team of researchers at MIT has found …
The experimental realization of extended, two-dimensional sheets of silicene, the silicon counterpart of graphene, has been elusive so far. Researchers have demonstrated that such a two-dimensional, epitaxial honeycomb Si layer forms through surface segregation on a metallic zirconium diboride (ZrB2) Film grown itself epitaxially on Si(111). The honeycomb Si layer uniformly covers the ZrB2(0001) surface …
Arxiv – Metamaterial-Enhanced Coupling between Magnetic Dipoles for Efficient Wireless Power Transfer (23 pages) Non-radiative coupling between conductive coils is a candidate mechanism for wireless energy transfer applications. In this paper, we propose a power relay system based on a near- field metamaterial superlens, and present a thorough theoretical analysis of this system. We use …
1. Kazakhstan plans to boost uranium output by 10 percent to 19,600 metric tons this year, said Vladimir Shkolnik, chief executive officer of the state nuclear company, Kazatomprom. The Central Asian nation produced 17,803 tons of uranium in 2010. 2. Areva SA, a French uranium miner, said production at its Trekkopje project in Namibia will …
Antennas that use plasma to focus beams of radio waves could bring multi-gigabit wireless networks The Wi-Gig standard is expected to go up to between 1 and 7 gigabits per second – fast enough to download a television programme in seconds. Wi-Gig requires higher radio wave frequencies : 60 gigahertz rather than the 2.4 GHz …
