A new study by Rice University scientists details exactly how carbon nanotubes snap when subjected to ultrasonic vibrations in a liquid. Carbon nanotubes — hollow tubes of pure carbon about as wide as a strand of DNA — are one of the most-studied materials in nanotechnology. For well over a decade, scientists have used ultrasonic …
UCLA researchers have developed a successful, scalable method for fabricating self-aligned graphene transistors with transferred gate stacks. By performing the conventional lithography, deposition and etching steps on a sacrificial substrate before integrating with large-area graphene through a physical transferring process, the new approach addresses and overcomes the challenges of conventional fabrication. With a damage-free transfer …
Kazakhstan can increase uranium production to 30,000 tons in 2-3 years, Novosti-Kazakhstan quoted deputy head of the Kazakh National Atomic Company Kazatomprom Nurlan Ryspanov as saying. “Our resources and existing capacities allow achieving production of 30,000 tons of uranium or more per year,” Ryspanov said on Wednesday while speaking at the 5th annual Central Asia …
Rand Simberg has an article in Popular Mechanics about Elon Musk and details of the Spacex reusable rocket plans. SpaceX is hard at work trying to design rocket parts that can fly themselves back to the launchpad for reuse. We talked to founder Elon Musk about how far the company’s designs have come. Musk tweet …
Space Solar Power: The First International Assessment of Space Solar Power: Opportunities, Issues and Potential Pathways Forward (272 pages by the International Academy of Astronautics) In the late 1960s, Dr. Peter Glaser of Arthur D. Little invented a fundamentally new approach to global energy: the Solar Power Satellite (SPS). The basic concept of the SPS …
Ecat World summarizes recent Andrea Rossi energy catalyzer comments from The Journal of Nuclear Physics site 1. Leonardo Corporation will be the sole manufacturers of the E-Cat reactors. Until now these reactors have been made by hand, but Rossi has said this process will be automated. Rossi has mentioned having plants or offices in Miami, …
The Economist magazine compares India and China over 13 metrics. China is far ahead on most of the statistical comparisons with longer life expectancy, more literacy and a better economy. The most recent 2011 Indian census statistics show an improvement in the literacy rate to 74% in India. China’s hidden economy adds another 25% to …
With all switches firing and central components cleaned, realigned, and in some cases even resurfaced, Focus Fusion-1 (FoFu-1) has pushed the frontier of DPF functioning to record pressures of fill gas. This is a prerequisite for achieving high fusion yields. The yield increases with the plasma density in the tiny plasmoid where fusion is produced, …
Electrolyte-Gated Organic Thin-Film Transistors (79 pages) There has been a remarkable progress in the development of organic electronic materials since the discovery of conducting polymers more than three decades ago. Many of these materials can be processed from solution, in the form as inks. This allows for using traditional high-volume printing techniques for manufacturing of …
Samsung showed its new Galaxy Note smartphone today at IFA. It is the rumored 5.3″ supersized smartphone. It has a stylus and 1280×800 high-resolution Super AMOLED screen. It is a thin Android phone additional functionality by way of both sketching and note-taking. It is powered by a 1.4 Ghz dual-core processor, 1GB RAM and more. …
Review Modern Physics – Electronic transport in two-dimensional graphene A broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature-dependent carrier transport in doped or gated graphene structures is provided. A salient feature of this review is a critical comparison between carrier transport in graphene and in two-dimensional semiconductor …
