“…This oxidation can be done chemically, with I 2 as the oxidant, [18,20] electrochemically, [21] or via autopolymerization. [21] We tested all three of these methods, described in detail in the SI, with the goal of depositing a thin, uniform film of MoS 6 on the Cu substrate. We then characterized these films with scanning electron microscopy (SEM), optical microscopy, X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy to analyze their uniformity and composition.…”

In lithium metal batteries (LMBs), the reaction between metallic Li and organic electrolytes consumes both Li and electrolyte, while the inhomogeneity of the resulting solid‐electrolyte interphase (SEI) contributes to inhomogeneous Li deposition. An artificial SEI, made by coating the Li surface with an electronically insulating material, can mitigate problems caused by uncontrolled SEI formation by 1) decreasing reduction of the electrolyte on the surface, and 2) increasing the uniformity of the Li+ flux to the electrode surface, thereby mitigating dendrite growth. In this work, we present a technique for coating the surface of LMB electrodes with sulfur‐rich molybdenum sulfide. This coating acts as an artificial SEI, which improves the coulombic efficiency and cycling stability of the LMBs by improving the reaction kinetics and decreasing the surface area of the exposed Li.

In earlier studies, we have collected experimental evidence (mostly from thin‐layer chromatography and polarimetry) on the spontaneous oscillatory in vitro chiral conversion of simple carboxylic acids dissolved in 70% aqueous ethanol. To elucidate this phenomenon, we developed a simple theoretical model of two linked Templators. Recently, we have obtained additional experimental evidence of the spontaneous condensation of chiral carboxylic acids, based on the biuret test (amino acids), high performance liquid chromatography, and 13C NMR spectroscopy (profens and hydroxy acids). We briefly describe our experimental results in the context of the existing literature and outline an improved theoretical model for these phenomena. Our system resembles in some respects the reported oscillatory condensation of organic silanols. Here, the key reaction is the formation of carboxylic acid‐derived enols. Finally, we discuss the importance of the oscillatory chiral conversion of simple carboxylic acids for biochemistry, pharmacology, and related life sciences. Copyright © 2010 John Wiley & Sons, Ltd.

“…The cathodic peak at ≈−0.8 V represents the formation of MoS 2 from the reduction of Mo. [6b] The anodic peak at ≈−0.2 V corresponds to a process producing MoS 3 that involves oxidation of a sulfide ligand, followed by an intramolecular electron transfer to molybdenum metal and loss of sulfur [11] ( Figure S2a Thus, the products are expected to be a mixture of MoS 2 and MoS 3 and denoted as MoS x in this work. The current responses increased with the proceeding scans indicative of materials growth.…”

Molybdenum sulfide/graphene composites are promising anode materials for lithium-ion batteries (LIBs). In this work, MoS /graphene composite film with an ideal 3D porous structure is developed via a facile and straightforward electrochemical route. The MoS nanoparticles are uniformly anchored on the graphene nanosheets that are randomly arranged, resulting in MoS /graphene composites with well-developed porous structure. Benefiting from such structure and the synergistic effect from two components, this material shows a high specific capacity over 1200 mA h g , an excellent rate performance, and superior cycling stability. The dominating pseudocapacitive behavior in Li storage contributes to the outstanding rate capacity. Importantly, this kind of novel material can be easily produced as 3D microelectrodes for microscaled LIBs that are highly demanded for autonomous microelectronic systems.
