Journal ArticleDOI
DNA charge transport over 34 nm
TL;DR: This work demonstrates DNA charge transport (CT) over 34 nm in 100-mer monolayers on gold, a distance that surpasses that of most reports of molecular wires.
Journal ArticleDOI
Elucidating anionic oxygen activity in lithium-rich layered oxides.
Jing Xu,Meiling Sun,Ruimin Qiao,Sara E. Renfrew,Lu Ma,Tianpin Wu,Sooyeon Hwang,Dennis Nordlund,Dong Su,Khalil Amine,Jun Lu,Bryan D. McCloskey,Bryan D. McCloskey,Wanli Yang,Wei Tong +14 more
TL;DR: The distinctive anionic oxygen activity of battery electrodes with different transition metals is revealed by elucidating the effect of the transition metal on oxygen redox activity by combining X-ray spectroscopy and operando differential electrochemical mass spectrometry.
Journal ArticleDOI
Residual lithium carbonate predominantly accounts for first cycle CO2 and CO outgassing of Li-stoichiometric and Li-rich layered transition metal oxides
TL;DR: The results highlight the importance of quantification of the surface contaminants and suggest that further research is needed to fully understand the long-term effects of trace surface Li2CO3, and warrant a reassessment of the notion of oxidative decomposition of carbonate electrolytes on T MO surfaces and, more generally, the reactivity of TMO surfaces.
Journal ArticleDOI
Electrochemical Oxidation of Lithium Carbonate Generates Singlet Oxygen
Nika Mahne,Sara E. Renfrew,Sara E. Renfrew,Bryan D. McCloskey,Bryan D. McCloskey,Stefan Freunberger +5 more
TL;DR: It is shown that highly reactive singlet oxygen (1O2) forms upon oxidizing Li2CO3 in an aprotic electrolyte and therefore does not evolve as O2 and therefore underpin the importance of avoiding 1O2 in metal‐O2 batteries, and question the possibility of a reversible metal-O2/CO2 battery based on a carbonate discharge product.
Journal ArticleDOI
Evolution of the Solid–Electrolyte Interphase on Carbonaceous Anodes Visualized by Atomic-Resolution Cryogenic Electron Microscopy

TL;DR: This work image the SEI on carbon black negative electrodes using cryogenic transmission electron microscopy (cryo-TEM) and track its evolution during cycling, finding that a thin, primarily amorphous SEI nucleates on the first cycle, which further evolves into one of two distinct SEI morphologies upon further cycling.
