Electrochemistry and Thermal Behavior of SiOx Made by Reactive Gas Milling
SiOx with various oxygen contents were synthesized from Si powder by a simple room-temperature ball milling method by controlling the air exposure time during milling. The resulting SiOx consists of nano and amorphous Si ... -
The Electrochemistry of Amorphous Si-B Thin Film Electrodes in Li Cells
Abstract Si1-xBx thin films of 0.071 ≤ x ≤ 0.950 have been synthesized using combinational sputtering. All Si1-xBx film compositions had a highly amorphous structure consisting of amorphous Si and B phases, as characterized ... -
Electrochemistry of Catalytically Graphitized Ball Milled Carbon in Li Batteries
High carbon Fe-C composites with starting concentrations of 10, 20, 30, and 40 wt% Fe (2.3 - 12.5 atomic % Fe) were prepared by ball milling followed by annealing. Increasing the Fe concentration and annealing temperature ... -
Electrochemistry of CuxSi1−x Alloys in Li Cells
The structure and electrochemistry in lithium cells of sputtered thin films and ball milled alloys in the Cu-Si system (0 ≤ x ≤ 0.60 in CuxSi1−x) were investigated. Both thin films and ball milled Cu-Si alloys showed the ... -

Engineered Particle Synthesis by Dry Particle Microgranulation
Highlights * A method of making monodisperse engineered ∼10-μm particles is introduced * Core-shell, spherical, and tetrahedral particles demonstrated at ∼100% yield * Spherical layered oxides for Li-ion batteries ... -
Explanation for the 4.8-V plateau LiCrxMn2-xO4
Using the results of photoelectron spectroscopy (PES) measurements on LiCrxMn2-xO4 we provide an explanation for the origin of the 4.8-V plateau in Li/LiCrxMn2-xO4 cells. PES shows that the d bands derived from Mn 3d e(g) ... -

Facial selectivity in the 4 + 2 reactions of a diene derived from carvone
The facial selectivities of cyclohexadienes bearing isopropenyl and isopropyl groups as plane-nonsymmetric substituents were assessed in 4 + 2 reactions with N-phenylmaleimide, tetracyanoethylene and 4-phenyl-1,2,4- ... -
Facile Deprotection of F-BODIPYs using Methylboronic Acid
4,4-Difluoro-4-bora-3a,4a-diaza-s-indacenes (F-BODIPYs) are deprotected through removal of the –BF2 moiety upon treatment with methylboronic acid. The tolerance of various substitution patterns about the dipyrrinato core ... -
The first series of alkali dipyrrinato complexes
The first series of alkali dipyrrinato complexes is reported, encompassing lithium, sodium, and potassium salts of meso-unsubstituted and meso-aryl-substituted derivatives. By varying the substituents at the meso position, ... -
First-principles study of the nuclear quadrupole resonance parameters and orbital ordering in LaTiO3.
The electronic structure of the distorted perovskite LaTiO3 is studied using d.-functional theory, implemented with a projector-augmented wave formalism together with the local-d. approxn. plus Hubbard U-parameter (LDA+U) ... -
