Applied Physics Letters – Single step, complementary doping of graphene A single-step doping method capable of high resolution n- and p-type doping of large area graphene is presented. Thin films of hydrogen silsesquoxane on exfoliated graphene are used to demonstrate both electron and hole doping through control of the polymer cross-linking process. This dual-doping is …
Angstron Materials gets a patent for their nano-graphene supercapacitors Angstron’s NGPs (nano graphene platelets) offer a cost effective, high performance alternative to carbon nanotubes and nanofibers. The first company to isolate and successfully produce large quantities of single-layer and multi-layer graphene sheets, Angstron’s nano graphene solutions eliminate the viscosity and dispersion problems associated with processing …
Centre for International Governance Innovation – The Future of Nuclear Energy to 2030 and its Implications for Safety, Security and Nonproliferation [40 page pdf] The purpose of this project was three-fold: • to investigate the likely size, shape and nature of the purported nuclear energy revival to 2030 – not to make a judgement on …
PC World says to expect the Apple Tablet to be released on Jan 27, 2010 and expect it to be like a giant iPod touch For business users, the tablet should offer access to supersized versions of iPhone applications, which could drive corporate acceptance of both devices. iPhone 4.0 software, expected to be introduced as …
This is a follow up to the Idaho National Labs achieving 19% burn of pebble fuel Pebble bed fuel could theoretically achieve 65% burn, but would require highly enriched fuel. Dr. Dave Petti [Laboratory Fellow, Director Very High Temperature Reactor (VHTR) Technology Development Office (TDO)] Currently our plans to do include going to those ultra …
MIT Technology review reports that a group from the German Sport University Cologne in Germany detected the real SARM (selective androgen receptor modulators)in a product called Andarine, available online for $100 and labeled as green tea extracts and face moisturizer. Selective androgen receptor modulators have steroid effects but are believed to be safer, without many …
New Nvidia Fermi-Based Tesla products deliver the performance of a CPU-based cluster at one-tenth the cost and one-twentieth the power The Tesla 20-series GPUs combine parallel computing features that have never been offered on a single device before. These include: * Support for the next generation IEEE 754-2008 double precision floating point standard * ECC …
Towns downstream of the station’s dam were said not to be at risk BBC News reports that an oil-filled transformer exploded at the Sayano-Shushenskaya power plant in Siberia, bringing down the ceiling of the turbine hall, which then flooded. RusHydro, the operator of the power station, said the damage would run into “billions of roubles” …
There were a lot of Emerging technologies presented at Siggraph 2009 [see this link for the list]. Here are several of those emerging technologies. Touchable Holography from the The University of Tokyo Ultrasound is used to focus force or sensation where it is precisely needed and wiimotes are used for handtracking. Recently, mid-air displays are …
Shwann cells are shown here in a salamander limb. When the limb regrew after being amputated, only these cells wrapped around nerve fibers; other cell types did not turn into Shwann cells. Credit: D. Knapp/E. Tanaka The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord — even …
Fujitsu Limited and Fujitsu Laboratories Ltd. today announced the development of the world’s first impulse radio-based high-capacity wireless transmission equipment using millimeter-band transmissions in the 70-100 gigahertz (70-100 GHz) range band, resulting in throughput exceeding 10 gigabits-per-second (10 Gbps). This technology dispenses with the oscillators and other components that have been required in conventional wireless …
