We seek to understand how the thermodynamics and kinetics of anthraquinone-containing self-assembled monolayer on silicon electrodes are affected by two key experimental variables: the intensity of the light assisting the anthraquinone/anthrahydroquinone redox process and the local solution environment. The substrates are chemically passivated poorly doped p-type silicon electrodes. The study presents a strategy for the selective modulation of either the anodic or the cathodic process occurring at the interface. Cyclic voltammetry studies showed that unlike for a proton-coupled electron transfer process performed at metallic electrodes, for the redox reaction of the anthraquinone unit on a silicon electrode it becomes possible …

LiV3O8 nanoparticles (primary particles with ca. 50 nm diameter) have been synthesized by flame spray pyrolysis (FSP). The powder was characterised by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and galvanostatic cycling. The initial discharge capacity of the LiV3O8 nanoparticles is 271 mAh g-1 when discharged from its open-circuit potential to 2.0 V vs Li/Li+ at a specific current of 100 mA g-1 under ambient conditions. The nanoparticles retained a specific discharge capacity of 180 mAh g-1 beyond 50 cycles. This paper describes the synthesis route as well as …

Nanosize molybdenum trisulfide, MoS3, was synthesized in a polyoxyethylene(2) nonylphenyl ether/cyclohexane/water microemulsion by acidifying ammonium tetrathiomolybdate solubilized in the water cores of inverse micelles. MoS3 was also prepared by thermal decomposition for comparison. X-ray diffraction, TEM, and electrochemical testing characterized the molybdenum trisulfide. By comparing the cyclic voltammetry results on MoS3 and S electrodes in lithium cells, the conclusions about the structure of MoS3 from previous research work have been confirmed. That is, the molybdenum trisulfide molecules were not a mixture of MoS2 and elemental S. Molybdenum trisulfide exists as Mo3S9 clusters, which are, in turn, linked by bridging SS …
