Topology gets magnetic: The new wave of topological magnetic materials
The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a “topological periodic table.” However, such a classification for magnetic materials has so far been elusive, and hence very few magnetic topological materials have been discovered to date. In a new study published in the journal Nature, an international team of researchers has performed…
ESA seeking dust-proof materials for lunar return
When humans return to the moon, they’ll have formidable challenge lying in wait: lunar dust. The talcum-like lunar regolith is considered the biggest operational problem facing moon colonists. Within a few days of dust exposure, Apollo spacesuits suffered obscured visors, clogged mechanisms and eroded suit layers. So an ESA team is looking into novel material options to serve as the basis…
The Arctic hasn’t been this warm for 3 million years
The last time CO2 concentrations reached today’s level was 3 million years ago, during the Pliocene Epoch. Hear from geoscientists who see evolving conditions in the Arctic as an indicator of how climate change could transform the planet. Source: https://earthsky.org/earth/arctic-warmest-3-million-years…
The Battle Over Chips is About to Get Uglier
“We’re in a new world where governments are more concerned about the security of their digital infrastructure and the resiliency of their supply chains,” Jimmy Goodrich, vice president of global policy with the Washington-based Semiconductor Industry Association, tells Bloomberg. “The techno-nationalist trends gaining traction in multiple capitals around the world are a challenge to the semiconductor industry.” At once highly globalized…

Print These Electronic Circuits Directly Onto Skin
An anonymous reader quotes a report from IEEE Spectrum: New circuits can get printed directly on human skin to help monitor vital signs, a new study finds. In the new study, researchers developed a way to sinter nanoparticles of silver at room temperature. The key behind this advance is a so-called a sintering aid layer, consisting of a biodegradable polymer paste…
Do the twist: Making two-dimensional quantum materials using curved surfaces
Scientists at the University of Wisconsin-Madison have discovered a way to control the growth of twisting, microscopic spirals of materials just one atom thick. …
A Group of Materials Called Perovskites Could Be a Game-Changer For Solar Power
Researchers from Australia have discovered that the widely acclaimed mineral perovskite can be used to transform the solar industry through cheaper and more efficient photovoltaics. The Independent reports: Perovskite, which is forged deep within the Earth’s mantle, has been hailed for its unprecedented potential to convert sunlight into electricity. Researchers have already improved its sunlight-to-energy efficiency from around 3 per cent…
Sweden’s New Car Carrier Is the World’s Largest Wind-Powered Vessel
An anonymous reader quotes a report from CNN: Oceanbird might look like a ship of the future, but it harks back to ancient maritime history — because it’s powered by the wind. The transatlantic car carrier is being designed by Wallenius Marine, a Swedish shipbuilder, with support from the Swedish government and several research institutions. With capacity for 7,000 vehicles, the…
