Calculated infrared absorption intensities of PAHs that underlie the interpretation of infrared emission from the ISM are validated with experiments. An adjusted emission model implies that typical PAH sizes are smaller than previously estimated.

Effect of depth of discharge (DOD) on cycling in situ formed Li anodes

Faraday Discuss., 2023, Advance Article
DOI: 10.1039/D3FD00079F, Paper
Kiwoong Lee, Jeff Sakamoto
This study demonstrates that the stability of cycling in situ Li anodes depends on their depth of discharge (DOD). High DOD cycling results in unstable performance due to the accumulation of interfacial degradation at Li/LLZO interfaces.

Operando detection and suppression of spurious singlet oxygen in Li–O2 batteries

Faraday Discuss., 2023, Advance Article
DOI: 10.1039/D3FD00081H, Paper
