Swedish solar energy expertMidsummer has been selected as supplier of flexible CIGS solar cells to be installed at the Vikingahallen sports arena in Märsta by the Sigtuna Municipality. Fasadglas AB's subsidiary FG Light Energy AB has been picked as the prime contractor and will carry out the installation of the solar cells from Midsummer on the sports arena.

It is the double helix, with its stable and flexible structure of genetic information, that made life on Earth possible in the first place. Now a team from the Technical University of Munich (TUM) has discovered a double helix structure in an inorganic material. The material comprising tin, iodine and phosphorus is a semiconductor with extraordinary optical and electronic properties, as well as extreme mechanical flexibility.

Successfully integrating two Advanced Vacuum plasma processing systems, is a South Korean research university, from Plasma-Therm into its nanotechnology fabrication lab, this supports multiple users engaged in wide-ranging nanotechnology research.Seoul National University lab researchers recently installed two Apex SLR systems with the well-proven Inductively Coupled Plasma (ICP) source technology from Plasma-Therm.

For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power — resulting in longer battery life, faster wireless communication and faster processing speeds for devices like smartphones and laptops.But a number of challenges have impeded the development of high-performance transistors made of carbon nanotubes, tiny cylinders made of carbon...

Last March, the AI program AlphaGo beat Korean Go champion LEE Se-Dol at the Asian board game. "The game was quite tight, but AlphaGo used 1200 CPUs and 56,000 watts per hour, while Lee used only 20 W. If a hardware that mimics the human brain structure is developed, we can operate artificial intelligence with less power," points out Professor YU Woo Jong.

Earlier this year, contract machining firm Norjon Precision Engineering upgraded its multi-tasking, turn-milling capacity with the addition of a Japanese-built Okuma Multus U3000 2SW from UK agent, NCMT.Coming equipped with a Y-axis on the column and a motorised B-axis tool carrier as well as a 12-station lower turret, the twin-spindle machine is capable of 3+2-axis machining, although fully interpolative 5-axis machining is an option.

The cost of solar power is beginning to reach price parity with cheaper fossil fuel-based electricity in many parts of the world, yet the clean energy source still accounts for just slightly more than 1% of the world’s electricity mix.Solar, or photovoltaic (PV), cells, which convert sunlight into electrical energy, have a large role to play in boosting solar power generation globally.

The wireless data transmission via mobile communication is reliable and affordable. However, data volume per user is rising exponentially. Causes are not only the continuously growing number of smartphones, but also trends as V2V or M2M communication – cars and machines need to communicate in high speed with each other. From 2020 the 5G mobile standard is aiming to transmit data rapidly and energy-efficiently.

Researchers at the University of Illinois at Urbana Champaign have developed a method for making brighter and more efficient green LEDs. Using an industry-standard semiconductor growth technique, they have created GaN cubic crystals grown on a silicon substrate that are capable of producing powerful green light for advanced solid-state lighting.

Engineers from the University of Utah and the University of Minnesota have discovered that interfacing two particular oxide-based materials makes them highly conductive, a boon for future electronics that could result in much more power-efficient laptops, electric cars and home appliances that also don't need cumbersome power supplies.Their findings were published in the scientific journal, APL Materials, from the American Institute of Physics.
