Reinforced Room temperature spin filtering in chiral paramagnetic metallopeptides [PDF]

open access: yes, 2019
Chiral-induced spin selectivity (CISS), whereby helical molecules polarize the spin of electrical current, is an intriguing effect with potential applications in nanospintronics. In this nascent field, the study of paramagnetic chiral molecules, which could introduce another degree of freedom in the control of the spin transport, remains so far ...

Regulating the Zn Electrode/Electrolyte Interface Toward High Stability– Insights from the Resting Time Impact on Zn Electrode Performance

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a close correlation among the resting period, the cyclability of the zinc anode, and the evolution of byproduct zinc hydroxide sulfate (ZHS) is identified. Furthermore, it is shown that proper control of the interfacial ZHS can significantly enhance the cycle performance of the zinc anode by effectively inhibiting corrosion and promoting

Electrical noise in electrolytes: a theoretical perspective [PDF]

open access: yesarXiv, 2023
Seemingly unrelated experiments such as electrolyte transport through nanotubes, nano-scale electrochemistry, NMR relaxometry and Surface Force Balance measurements, all probe electrical fluctuations: of the electric current, the charge and polarization, the field gradient (for quadrupolar nuclei) and the coupled mass/charge densities. The fluctuations
