Super magnets from a 3-D printer

Magnetic materials are an important component of mechatronic devices such as wind power stations, electric motors, sensors and magnetic switch systems. Magnets are usually produced using rare earths and conventional manufacturing ...

Where is the greatest risk to our mineral resource supplies?

Policymakers and the U.S. manufacturing sector now have a powerful tool to help them identify which mineral commodities they rely on that are most at risk to supply disruptions, thanks to a new methodology by the U.S. Geological ...

REE mineral-bearing rocks found in eastern Mojave Desert

Scientists from the U.S. Geological Survey (USGS) have mapped a rare earth element deposit of magmatic carbonatite located in the Mountain Pass region of the eastern Mojave Desert. The new report details the geophysical and ...

An alloy that retains its memory at high temperatures

Using computer simulation, Alberto Ferrari calculated a design proposal for a shape memory alloy that retains its efficiency for a long time even at high temperatures. Alexander Paulsen manufactured it and experimentally ...

Magnesium takes ShAPE

Two forms of magnesium material that were processed into tubing using a novel manufacturing technology called Shear Assisted Process and Extrusion—or ShAPE—were found to have quite similar and improved microstructures, ...

Magnets sustainably separate mixtures of rare earth metals

A new study describes a novel approach for purifying rare earth metals, crucial components of technology that require environmentally-damaging mining procedures. By relying on the metal's magnetic fields during the crystallization ...

Geochemists measure new composition of Earth's mantle

What is the chemical composition of the Earth's interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth's deep interior often provide such information. ...

Tomorrow's coolants of choice

Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating. Meanwhile, the increasing penetration of cooling applications into ...
