In a ceremony today at General Dynamics Mission Systems’ Taunton facility, company officials as well as representatives from the U.S. Navy formally opened the General Dynamics Mission Systems Unmanned Undersea Vehicle (UUV) Manufacturing and Assembly Center of Excellence.
The Semiconductor Industry Association (SIA) today announced worldwide sales of semiconductors were $44.5 billion in June 2021, an increase of 29.2% from the June 2020 total of $34.5 billion. Sales in June were 2.1% more than the May 2021 total of $43.6 billion. Sales during the second quarter of 2021 were $133.6 billion, an increase of 29.2% over the second quarter of 2020 and 8.3% more than the first quarter of 2021. Monthly sales are compiled by the World Semiconductor Trade Statistics (WSTS) organization and represent a three-month moving average. SIA represents 98% of the U.S. semiconductor industry by revenue and nearly two-thirds of non-U.S. chip firms.
Finding a thermal insulation that can withstand the highly corrosive conditions of chemical tanks and chemical plant heat process equipment has been virtually impossible. The constant exposure to acids and bases and everything in between wreaks havoc on conventional thermal insulation and severely limits both the lifespan and performance qualities of the insulation.
Zhao went on to study nuclear engineering at the National Institute for Nuclear Science and Technology in France, where he tuned into the details of nuclear technology and the societal implications of nuclear energy development.
An electron beam with sub-atomic precision, allowing scientists to directly see each atom in two-dimensional materials like graphene, and also to target single atoms with the beam. Each electron has a tiny chance of scattering back from a nucleus, giving it a kick in the opposite direction.
Generating electrical power from waste heat New Sandia solid-state silicon device may one day power space missions...
Scientists discovered the phenomenon 30 years ago, but the mechanism for superconductivity remains an enigma because the majority of materials are too complex to understand QPT physics in details. A good strategy would be first to look at less complicated model systems.
UT Dallas physics researchers recently published a study in the journal Science that describes the high thermal conductivity of boron arsenide crystals they grew in the lab. From left: study authors Xiaoyuan Liu, Dr. Bing Lv and Dr. Sheng Li.
Researchers at Caltech have developed an artificial neural network made out of DNA that can solve a classic machine learning problem: correctly identifying handwritten numbers. The work is a significant step in demonstrating the capacity to program artificial intelligence into synthetic biomolecular circuits.
Nanoscale Kirigami has taken off as a field of research in the last few years; the approach is based on the ancient arts of origami (making 3-D shapes by folding paper) and kirigami (which allows cutting as well as folding) but applied to flat materials at the nanoscale, measured in billionths of a meter.
Semiconductor quantum dots (nanocrystals just a few nanometers in size) have attracted researchers’ attention due to the size dependent effects that determine their novel electrical and optical properties. By changing the size of such objects, it is possible to adjust the wavelength of the emission they absorb, thus implementing selective photodetectors, including those for UV radiation.
Polymer plastic solar cells remain an industry priority because of their light weight, flexibility and cost-effectiveness. Now scientists from Stony Brook University and the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have demonstrated that these types of solar cells can be more efficient and have more stability based on new research findings.
