Improved Etching for Chips and 3D transistor materials to get to 10 nanometer features and five times faster conductance

1. University of Illinois researchers developed a method to chemically etch patterned arrays in the semiconductor gallium arsenide, used in solar cells, lasers, light emitting diodes (LEDs), field effect transistors (FETs), capacitors and sensors. Led by electrical and computer engineering professor Xiuling Li, the researchers describe their technique in the journal Nano Letters. Metal-assisted chemical …

Japanese, Russian scientists see high chance of cloning mammoth within 5 years

Scientists believe it may be possible to clone a woolly mammoth within five years after finding well-preserved bone marrow in a thigh bone recovered from permafrost soil in Siberia. Teams from Russia’s Sakha Republic’s mammoth museum and Japan’s Kinki University will launch fully-fledged joint research next year aiming to recreate the giant mammal, Japan’s Kyodo …

Alberta targets reducing oilsand emissions to below conventional oil, creating a lot jobs and a budget surplus

Alberta’s Premier Ed Stelmach loftiest goal would be cutting oil sands’ greenhouse-gas emissions to a level below conventional oil. Currently, they’re about 25 per cent higher, and most new development is in situ, or underground, bitumen deposits – the extraction of which produces more carbon than open pit bitumen mining. He had initially pledged to …

Elusive spintronics success could lead to single chip for processing and memory

Researchers from Queen Mary, University of London (UK) and the University of Fribourg (Switzerland) have shown that a magnetically polarised current can be manipulated by electric fields. This important discovery opens up the prospect of simultaneously processing and storing data on electrons held in the molecular structure of computer chips – combining computer memory and …

Technology Roundup – Quantum computer Algorithm

1. MIT Technology Review: Seth Lloyd describes the utility of the new quantum computing algorithm for linear equations. MIT researchers, however, have developed a new algorithm that could solve systems of linear equations with exponential speed–improving video processing, weather modeling, and population analysis, among other applications. For even the easiest trillion-­variable problems, “a supercomputer’s going …

Singapore Has Ultra High 5 nanometer Resolution Electron Beam

Ultra-high-density data storage is now a step closer thanks to an advance in device fabrication achieved by Bao-Yu Zong and co-workers from the Data Storage Institute of A*STAR in Singapore. Devices for data-storage applications are created by depositing a ‘resist’ material onto a substrate, which is etched into a pattern using an electron beam and …
