Currently, low-alloy aluminium is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements to aluminium alloys.
TAMPA, Fla. (July 6, 2020) — As the death toll from the COVID-19 pandemic mounts, scientists worldwide continue their push to develop effective treatments and a vaccine for the highly contagious respiratory virus.
GAINESVILLE, Fla. --- In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as the tropics. The finding runs counter to a long-held hypothesis that tropical regions, home to the planet's richest biological diversity, outpace their temperate counterparts in producing new species.
DALLAS - July 6, 2020 - UT Southwestern researchers have identified vast webs of small snippets of the genome that interact with each other and with genes to promote prostate cancer. Their findings, published June 22 in the Journal of Clinical Investigation, could lead to new ways to treat the most common type of malignancy in American men other than skin cancer.
It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields. Scientists at the National Institute of Standards and Technology (NIST) have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously. Together, these measurements can uncover new knowledge about a wide range of special materials that are crucial for developing the next generation of quantum computers, communications and a host of other applications.
The development of metasurfaces opened a horizon for the advance of planar optics. Among various metadevices, the metalens has attracted widespread attention for practical applications in imaging and spectroscopy, where it allows multifunctional wavefront manipulations for improved focus.
"Running in Tarahumara (Rarámuri) Culture," just published in Current Anthropology (v61, no. 3 (June 2020): 356-379) studies the Tarahumara Native Americans of northern Mexico. For over a century, the Tarahumara have been famous for their long distance running traditions and abilities, with many accounts claiming they have superhuman athletic abilities that partly result from being uncontaminated by westernization.
Researchers in the Cockrell School of Engineering at The University of Texas at Austin have built a new type of battery that combines the many benefits of existing options while eliminating their key shortcomings and saving energy.
The reniform nematode is one of the most commonly found pests of cotton, with the ability to cause severe economic damage. In order to assess exactly how much damage the reniform nematode can cause, plant pathologists at Auburn University conducted a field trial comparing a clean field to a reniform-infested field.
More than 40% of energy consumption in the European Union is by buildings and 63% of this figure is due to residential dwellings. Furthermore, more than 75% of domestic energy consumption is related to heating and the production of clean hot water. These data highlight the need to look for alternative sources of energy in line with the EU's 2030 targets that seek a sustainable transition from fossil fuels to renewable energies and to reduce emissions of greenhouse gases.
Scientists have made a pivotal breakthrough in the important, emerging field of spintronics - which could lead to a new high speed energy efficient data technology.
An international team of researchers, including the University of Exeter, has made a revolutionary discovery that has the potential to provide high speed, low power-usage for some of the world's most well-used electronic devices.
Superconductivity is a physical phenomenon occurring at low temperatures in many materials which manifests itself through a vanishing electrical resistance and the expulsion of magnetic fields from the material's interior. Superconductors are already used for medical imaging, fast digital circuits or sensitive magnetometers and hold a great potential for further applications. However, the conductivity of the majority of technologically important superconductors is in fact not "super".
An international team led by physicists from the Ludwig-Maximilians Universitaet (LMU) in Munich realized a novel genuine time-dependent topological system with ultracold atoms in periodically-driven optical honeycomb lattices.
Topological phases of matter have attracted a lot of interest due to their unique electronic properties that often result in exotic surface or boundary modes, whose existence is rooted in the non-trivial topological properties of the underlying system. In particular, the robustness of these properties makes them interesting for applications.
The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems.
Lithium ion batteries (LIBs) have many advantages but there are much more abundant metallic elements available such as sodium, potassium, zinc and aluminum.
Characteristics of palm trees differ from those of other tropical trees in many ways. In a major new study led by scientists at Uppsala University, Sweden, and University of Campinas, Brazil, they have surveyed the actual numbers of palms in tropical rainforests around the globe. The proportion of palm trees is important to include in calculations of forests' potential carbon storage and in estimates of forested areas' sensitivity to climate change.
