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.

As countries invest in large-scale clean energy transition programs and begin to phase out internal combustion engines, securing the minerals required to build batteries for storing renewable energy and powering electric vehicles is increasingly critical.

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.

Likewise, a vehicle with a battery pack that happens to be near the upper range of its charge window (~70% to 80% for many hybrids) will also be limited in its ability to convert braking force to stored energy during a given braking event. Some early hybrid vehicles employed regen in tandem with a conventional hydraulic braking system.

In January 1981, a handful of semiconductor engineers at MOS Technology in West Chester, Pa., By using in-house integrated-circuit-fabrication facilities for prototyping, the engineers had cut the design time for each chip to less than nine months, and they had designed and built five prototype computers for the show in less than five weeks.

I learned that the lithography process used to create features on computer chips was at a crisis point, one that offered intriguing engineering challenges. Lithography systems in the 1980s used mercury lamps that radiated at wavelengths of 436 nanometers (violet light) and eventually 365 nm (near-ultraviolet).
