Researchers at Chalmers University of Technology, Sweden, have developed a method that can reduce the levels of mercury in sulfuric acid by more than 90%, even from low levels. An open-access paper on the method is published in ACS ES&T Engineering. Recycled streams in the smelters can also contain mercury.

A recent United Nations provision has banned the use of mercury in spacecraft propellant. Although no private company has actually used mercury propellant in a launched spacecraft, the possibility was alarming enough—and the dangers extreme enough—that the ban was enacted just a few years after one U.S.-based Mercury is a neurotoxin.

Like most ores and soils, bauxite can contain trace quantities of metals such as arsenic, beryllium, cadmium, chromium, lead, manganese, mercury, nickel and naturally-occurring radioactive materials, such as thorium and uranium. Industrial filtration consists in applying a mechanical pressure to dry bauxite residue, making it easier to store.

Over the years, memory has been made up of vacuum tubes, glass tubes filled with mercury and, most recently, semiconductors. The first electronic digital computer capable of storing instructions and data in a read/write memory was the Manchester Small Scale Experimental Machine, known as the Manchester “Baby.”

In 1911, Dutch physicist Heike Kamerlingh Onnes plunged a mercury wire into liquid helium and noticed that the wire’s electrical resistance vanished. Here are five emerging uses for HTS that could transform everyday life—if engineers can work out the kinks. The wire had become a “superconductor.”

It’s now or never if humans hope to prevent the mercury from increasing by 1.5° It’s possible to construct off-grid charging stations, but they come with hassles, such as storing power when the sun doesn’t shine. Engineers and legal minds will continue to address the problems keeping such facilities from proliferating.

How 3M Became a Key Innovator in the Production of Magnetic Data Storage Now, to be clear, 3M did not invent magnetic storage—that was done by Austro-German engineer Fritz Pfleumer , in 1928. I bought them from a junk store, and maybe paid $2 for them. I admittedly have long had a fascination with these reel-to-reel tapes.
