Carbon‐Sheathed MoS2 Nanothorns Epitaxially Grown on CNTs: Electrochemical Application for Highly Stable and Ultrafast Lithium Storage

“…To quantify the electrochemical parameters, the impedance plots are fitted to the Randles equivalent electrical circuit (Figure S7, Supporting Information). It can be noticed that R ct after the first cycle is high (Table S3, Supporting Information), however, it decreases significantly in subsequent cycles, which is owing to the activation of the electrode material and the improved infiltration of the electrolyte into the electrode, and thus can result in an improved electrochemical reaction kinetics upon cycling.…”

“…The inclined line represents Warburg impedance (W) related to the diffusion of lithium ions within the bulk of the electrode material. It can be noticed that R ct after the first cycle is high (Table S3, Supporting Information), however, it decreases significantly in subsequent cycles, which is owing to the activation of the electrode material and the improved infiltration of the electrolyte into the electrode, [62,65] and thus can result in an improved electrochemical reaction kinetics upon cycling.

Microbial and soil properties in bentgrass putting greens: Impacts of nitrogen fertilization rates

“…Peaks in both solid and liquid fractions included C-O stretching of polysaccharides represented in peaks around 1100 cm −1 ; C=O stretching of carboxylic acids, amides, quinones, and ketones around 1600 cm −1 ; and O-H stretching of carboxylic acids, phenols, alcohols and/or N-H stretching of amines and amides around 3450 cm −1 . Extractable fraction possessed several peaks at 2080-2270 cm −1 corresponding to C`N or N`N triple bond in configurations such as acetylide, isocyanate, isonitrile and nitrile (Bouchet-Fabre et al, 2005;Cataldo, 1998). Solid fraction contained C`N or N`N peak only around 2080 and additionally it had a major aliphatic C-H stretching at~2920 cm −1 and several peaks at 1850-2000 cm −1 .…”

Effect of ECR-assisted microwave plasma nitriding treatment on the microstructure characteristics of FCVA deposited ultra-thin ta-C films for high-density magnetic storage applications

“…As well known, the incorporation of N atom into nitrogenated ta-C films is greatly influenced by the film deposition methods and specific growth conditions [12,13]. However, it has been mainly reported by some research groups for the nitrogen incorporation into ultra-thin ta-C films during direct FCVA deposition process [4,10,13], and the incorporation behavior has remained inefficient because the appealing diversity of the bonding configurations allows nitrogen to be incorporated in many conditions [8,14].…”
