—2022’s top chemistry research, by the numbers “These interesting integers caught the attention of C&EN’s editors” 77 mA h/g The charge capacity of a 3D-printed lithium-ion battery electrode, which is over three times as high as that of a conventionally made electrode. The 3D-printing technique aligns graphite nanoflakes in the material to optimize the flow of lithium ions in and out of the electrode (research reported at the ACS Spring 2022 meeting). 80-95% Percentage of gasoline-sized hydrocarbon molecules allowed through a polymer membrane.

That vaccine also numbers among 2022’s approvals; while the FDA granted Moderna’s COVID-19 jab an emergency use authorization (EUA) in late 2020—just a week after Pfizer and BioNTech’s EUA—its full FDA approval came in January this year. Big companies dominated approvals, says Sara LaFever, executive director of research and commercial support at the pharmaceutical intelligence firm Citeline.

Together with researchers from industry and other military labs, Bob Ware, a specialist in metallurgical failure analysis at the AFRL, examined the C-130’s failed blade and the 15 other blades that remained intact. The team determined that the root cause of the blade’s failure was a fundamental electrochemical process known as galvanic corrosion, a form of damage that can occur between electrochemically dissimilar metals that are in direct contact.

The challenge of getting real numbers on scope 3 emissions is steep, Chalvon Demersay says, and PCF accounting requires the same level of accuracy as financial accounting. Access to actual, or primary, data is essential, he says, noting that most companies currently use secondary data such as historical averages for the production and transportation of purchased goods.

COVID-19’s olfactory effects aren’t confined to a loss of smell. For some, infection causes the smells that people typically relish or find comfort in—like the morning’s coffee— to trigger a full-throttle sense of disgust or revulsion. Kelly is well placed to explain the overwhelming effects that a loss and distortion of smell can wreak and how the pandemic brought those changes into focus.
