Journal ArticleDOI
A Comparative Study of Synthetic Graphite and Li Electrodes in Electrolyte Solutions Based on Ethylene Carbonate‐Dimethyl Carbonate Mixtures
TL;DR: In this article, a comparative study of both Li and synthetic graphite electrodes in electrolyte solutions based on ethylene and dimethyl carbonates (EC-DMC) and the impact of the salt used was investigated.
Journal ArticleDOI
Bulk Synthesis of Inorganic Fullerene-like MS2 (M = Mo, W) from the Respective Trioxides and the Reaction Mechanism
Yishai A. Feldman,Gitti L. Frey,M. Homyonfer,Vera Lyakhovitskaya,L. Margulis,Hagai Cohen,Gary Hodes,John L. Hutchison,Reshef Tenne +8 more
TL;DR: Srolovitz et al. as mentioned in this paper used a closed layer of MS2, which isolates the nanoparticle from its surroundings and prevents its fusion into larger particles, and then converted the oxide core of a nanoparticle into a sulfide nanoparticle with an empty core (IF).
Journal ArticleDOI
Inorganic fullerene-like material as additives to lubricants: structure–function relationship
Lev Rapoport,Yishay Feldman,M. Homyonfer,Hagai Cohen,Jeremy Sloan,John L. Hutchison,Reshef Tenne +6 more
TL;DR: In this paper, inorganic fullerene-like (IF) supramolecules of metal dichalcogenide MX2 (M=Mo, W, etc.; X=S, Se), materials with structures closely related to (nested) carbon fullerenes and nanotubes have been synthesized.
Journal ArticleDOI
X-ray photoelectron spectroscopy studies of lithium surfaces prepared in several important electrolyte solutions. A comparison with previous studies by Fourier transform infrared spectroscopy
TL;DR: In this article, a set of solvents, propylene carbonate (PC), ECC−dimethyl carbonate mixtures, and 1,3-dioxolane, were investigated with respect to the effect of storage time.
Journal ArticleDOI
Alkali Metal Intercalated Fullerene-Like MS2 (M = W, Mo) Nanoparticles and Their Properties
Alla Zak,Yishay Feldman,Vera Lyakhovitskaya,Gregory Leitus,Ronit Popovitz-Biro,Ellen Wachtel,Hagai Cohen,Shimon Reich,Reshef Tenne +8 more
TL;DR: Recovery of the pristine compound properties (diamagnetism and semiconductivity) was observed as a result of deintercalation.
