(A) Automated crystal orientation mapping showing the grain orientations in the vicinity of the interface of interest. The boundary of interest separates the two indicated grains, labeled as A and B, at the center of image (B) and terminates at triple … Read more

Geologists mapped how metal pollutants have traveled across the city

Credit: Pixabay/CC0 Public Domain Pittsburgh’s steel industry may be largely in the past, but its legacy lives on in city soils. New research led by Pitt geologists shows how historical coking and smelting dropped toxic metals in Pittsburgh’s soil, particularly in the eastern half of the city. “I don’t think people need to be scared, … Read more

Researchers attempt to print thin-film transistors with metal oxides onto heat-sensitive materials

NASA’s metal asteroid mission Psyche won’t launch this year

Space fans have one fewer rocket launch to look forward to this year. NASA’s Psyche mission designed to visit a metal-rich asteroid is facing an uncertain future after software testing issues forced an extended launch delay expected to last at least until July 2023, mission managers announced Friday (June 24). NASA is convening an independent … Read more

Giving metal to microbes could reduce greenhouse gas

Marsh wetland at Argonne National Laboratory. Credit: Jeffrey Catalano Like you and me, microbes need some metals in their diet to stay healthy. The metals help the microbes fully “digest” food. After a good meal, the microbes that gain energy by chemically reducing nitrate release a harmless byproduct: nitrogen, the gas that makes up 78% … Read more

New maps of asteroid Psyche reveal an ancient world of metal and rock

Astronomers at MIT and elsewhere have mapped the composition of asteroid Psyche, revealing a surface of metal, sand, and rock. Credit: NASA Later this year, NASA is set to launch a probe the size of a tennis court to the asteroid belt, a region between the orbits of Mars and Jupiter where remnants of the … Read more

Jupiter is up to 9% Rock and Metal, Which Means it Ate a lot of Planets in its Youth

Jupiter is almost composed entirely of hydrogen and helium. The amounts of each closely conform to the theoretical quantities in the primordial solar nebula. But it also contains other heavier elements, which astronomers call metals. Even though metals are a small component of Jupiter, their presence and distribution tell astronomers a lot. According to a … Read more

Astronomy team finds evidence of galactic metal shrouded in dust

NASA’s SOFIA airborne observatory enabled a UCI-led team of astronomers to study infrared emissions from five nearby galaxies. The researchers found more metal than expected in the intergalactic medium, a result that would have been difficult to achieve without the power of viewing infrared radiation through thick galactic dust.

Nanoracks experiment poised to demonstrate metal cutting in orbit – Spaceflight Now

The Outpost Mars Demo-1 payload ready for launch on SpaceX’s Transporter 5 rideshare mission. Credit: Nanoracks Nanoracks will fly an experiment with a small articulating robot arm on SpaceX’s Transporter 5 rideshare mission this week to demonstrate metal cutting in orbit, a test lasting just minutes that could advance in-space manufacturing technology to help convert … Read more
