Tracing the origin of lithium in Li-ion batteries using lithium isotopes.

Rechargeable lithium-ion batteries (LIB) play a key role in the energy transition towards clean energy, powering electric vehicles, storing energy on renewable grids, and helping to cut emissions from transportation and energy sectors. Lithium (Li) demand is estimated to increase considerably in the near future, due to the growing need for clean-energy technologies. The corollary is that consumer expectations will also grow in terms of guarantees on the origin of Li and the efforts made to reduce the environmental and social impact potentially associated with its extraction.

Reactivity and Specificity of RNase T, RNase A, and RNase H toward Oligonucleotides of RNA Containing 8-Oxo-7,8-dihydroguanosine.

Understanding how oxidatively damaged RNA interacts with ribonucleases is important because of its proposed role in the development and progression of disease. Thus, understanding structural aspects of RNA containing lesions generated under oxidative stress, as well as its interactions with other biopolymers, is fundamental. We explored the reactivity of RNase A, RNase T, and RNase H toward oligonucleotides of RNA containing 8-oxo-7,8-dihydroguanosine (8oxoG).
