Engineers reveal cause of key sodium-ion battery flaw
Sodium-ion batteries are a promising technology for electric vehicles, the energy grid and other applications because they are made from abundant materials that are energy dense, nonflammable and operate well in colder temperatures. But engineers have yet to perfect the chemistry. While the lithium-ion batteries found in modern electronics can recharge thousands of times, most variations of sodium-ion batteries can only cycle a small fraction of that.
How two cancer drugs can look the same but behave differently - revealed by serial room temperature crystallography
Cancer cells often overexpress glutaminase enzymes, in particular glutaminase C (GAC), which resides in the mitochondria and catalyzes the hydrolysis of glutamine to glutamate. High levels of GAC have been observed in aggressive cancers and the inhibition of its enzymatic activity has been shown to reduce their growth and survival, both in vitro and in mouse models. Numerous GAC inhibitors have been reported, with the most heavily investigated being a class of compounds derived from the small molecule BPTES (bis-2-(5-phenylacetamido-1,3,4-thiadiazol-2-yl)ethyl sulfide).

X-ray technique offers new view inside active batteries
Despite the everyday prevalence of batteries, scientists still have many questions about the chemistry happening inside them. Common techniques to study batteries help to detail the structural phases of materials or the charge state of individual ions, but fail to show the relationship of both as the battery is operating.
CHESS Town Hall
CHESS is hosting a Virtual User Town Hall.

AI powers autonomous materials discovery
When a master chef develops a new cake recipe, she doesn’t try every conceivable combination of ingredients to see which one works best. The chef uses prior baking knowledge and basic principles to more efficiently search for that winning formula.
Materials scientists use a similar method in searching for novel materials with unique properties in fields such as renewable energy and microelectronics. And a new artificial intelligence tool developed by Cornell researchers promises to rapidly explore and identify what it takes to “whip up” new materials.
