Biobased 1,4-butanediol (BDO)—a starting material for many foams, plastics, and fibers—has been a star performer for the company. The firm licensed its bio-BDO process to the bioplastics firm Novamont, which started up a 30,000-metric-ton-per-year plant in Italy in 2016. More recently, it licensed the technology to Qore, a joint venture between the chemical distributor Helm and the agriculture giant Cargill.

It comes after more than 60 years of research in which scientists and engineers have worked on designing laboratory equipment that can simulate the extreme temperatures and pressures that drive fusion in the cores of the sun and other stars and inside exploding nuclear weapons. Fusion can occur when two extremely energetic atoms slam together.

They used these inks to make tattoo patterns such as stars and chevrons in samples of pig skin. Then they developed a mobile app to decode the colors from the tattoos (Angew. Chem., Int. Ed. 2019, DOI: 10.1002/anie.201904416). “We can utilize this smartphone camera as a portable spectrophotometer,” he says.

Gateway to the stars Astronauts have been conducting scientific research in space since the early days of spaceflight. In the 1970s, experiments aboard Russia’s Salyut stations and the US’s Skylab included many studies in biomedicine, which focused on the physiological impacts of human spaceflight, the biological mechanisms of those effects, and lifestyle interventions to counter them.
