Nanotechnology for sustaining environment: A key player
Vacuum Technology and Coating
The issue of environmental pollution has become a hot issue in today's world. Environmental pollution, mainly caused by toxic chemicals, includes air, water, and soil pollution. This pollution results not only in the destruction of biodiversity, but also the degradation of human health. Nanotechnology offers many advantages to improve existing environmental technologies and create new technology that is better than current technology.

US solar market added more than two gigawatts in first quarter of 2017, new study shows
CNBC
The solar market in the U.S. added 2,044 megawatts – just over two gigawatts (GW) – of new photovoltaic capacity in the first quarter of 2017, according to the latest U.S. Solar Market Insight Report. The report, from GTM Research and the Solar Energy Industries Association (SEIA), said that total installed capacity hit 44.7 GW, enough to power more than 8 million homes. In addition, utility-scale prices fell below $1 per watt for the first time.

Beyond scaling: An electronics resurgence initiative
ECN
The Department of Defense’s proposed FY 2018 budget includes a $75 million allocation for DARPA in support of a new, public-private “electronics resurgence” initiative. The initiative seeks to undergird a new era of electronics in which advances in performance will be catalyzed not just by continued component miniaturization but also by radically new microsystem materials, designs, and architectures.

Scientists help thin-film ferroelectrics go extreme
Phys.org
Scientists have greatly expanded the range of functional temperatures for ferroelectrics, a key material used in a variety of everyday applications, by creating the first-ever polarization gradient in a thin film. The achievement, reported May 10 in Nature Communications by researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), paves the way for developing devices capable of supporting wireless communications in extreme environments, from inside nuclear reactors to Earth's polar regions.

TECHNICAL TIPS


What you need to know about gold evaporation
Gold evaporation is a popular but troublesome process. Gold, when molten, has 2 issues:
    1) it is corrosive and will eat through the boat eventually, and;
    2) gold will try to migrate to cooler areas of the boat (where it is mounted).
Our alumina coated tungsten boats are ideal to solve these problems. For example, with the S21-AO-W, the entire dimple area is coated with alumina. This prevents the gold from wetting to the tungsten thus eliminating migration and corrosion. However, this boat takes about 30 percent more power than an uncoated boat due to the alumina coating.

On the other hand, our S42B-AO-W barrier style boat, solves the migration issue by letting the gold wet to the dimple area, but the AO coating prevents the gold from leaving the dimple area. The .010” thick tungsten is thick enough to withstand the corrosiveness for a few runs. We also offer high purity gold pellets in a variety of sizes and quantities.
