Solvent Effects on Electrophilicity

open access: yesJournal of the American Chemical Society, 2001
Continuum solvent effect on the electrophilicity index recently proposed by Parr and co-workers (Parr, R. G.; von Szentpaly, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922) is discussed in detail. Solvent effect is introduced using the self-consistent isodensity polarized continuum model (SCI-PCM).

Novel Approach to the Preparation of Lead Chalcogenide Colloidal Quantum Dots and Properties Thereof

open access: yesMaterials Proceedings, 2023
In this work, we report the study of resizing of lead chalcogenide quantum dots, both PbS and PbSe, in the presence of the oleylamine/oleic acid mixture. We demonstrate that the resizing of lead chalcogenide nanocrystals could be performed in aprotic non-

High sulfur-doped microporous carbon for high-rate potassium ion storage: Interspace design and solvent effect

open access: yes, 2023
Carbon materials as promising anode for potassium ion batteries (PIBs) suffer from low rate performance, which is attributed to sluggish K+ transport stemming from limited carbon interspace and elusive solvent effect.
