Journalists visited the Alterra plant in November during a trip organized by the American Chemistry Council, a trade group keen on promoting plastics recycling by pyrolysis, depolymerization, and other emerging techniques the industry calls advanced recycling. Industry aims for such technologies to take hold and thereby improve the image of the plastics industry.

The firm says it uses machine learning to conduct peptide synthesis, analysis, and purification 30 times as fast as traditional techniques. Fujifilm will acquire Shenandoah Biotechnology, a Warminster, Pennsylvania–based manufacturer of recombinant proteins. Shenandoah recently launched a line of cytokines and growth factors.

“The number of discoveries in biomedicine that have had the impact that Jennifer’s and Emmanuelle’s had can be counted on the fingers of one hand: recombinant DNA, PCR [polymerase chain reaction], DNA sequencing, and now CRISPR,” says Fyodor Urnov, a gene-editing scientist at the University of California, Berkeley.

The problem, says Elisa Fadda, a computational glycobiologist at Maynooth University, is that the sugars move around too much and can’t be captured by most structural biology techniques. “You can just see little bits like stumps of trees,” she says. The only time you can see them is when they interact strongly with the protein, which reduces their flexibility and movement.

The laser burned and depolymerized the Kevlar fibers and the carbon atoms recombined to form graphene, as shown by Raman spectroscopy. Using a motorized setup for the laser, they were able to scribe any design on the textile in minutes. The team used the technique to make a zinc-air battery, where one of the battery electrodes was the graphene-Kevlar textile coated with a cobalt oxide compound and the other electrode was zinc.
