At ASDEX upgrade (AUG) a new framework for the evaluation of impurity densities based on measurements from charge exchange recombination spectroscopy (CXRS) diagnostics has been developed. The concentration analysis code, or CHICA, can perform these calculations all beam-based CXRS at AUG and is equipped with atomic data regularly measured spectral lines (He, Li, B, C, N, O, Ne). CHICA includes four different methods neutral density populations, which feature implementations contain varying...
Abstract Three new derivatives of methoxyphenyl‐substituted bis(picolyl)phosphines 3 – 5 , the CH 2 TMS substituted bis(picolyl)phosphine ( 6 ) and related phosphine oxides 2b 5b have been synthesized. Syntheses were accomplished by reacting corresponding dichlorophosphines with picolylTMS 7 ). An improved synthesis most starting materials is also presented enables increased ligand yields in all cases. The are extensively characterized 1 H, 13 C 31 P NMR spectroscopy and, case literature...
A successful biomolecule-assisted, non-toxic solvothermal synthesis for CuInS<sub>2</sub> on TCO substrate with desirable absorption behavior and band gaps is presented.
Abstract We present a facile two‐step synthesis of vanadium (III) oxide/carbon core/shell hybrid material for application as lithium‐ion battery electrode. The first step is thermal treatment mixture carbide (VC) and NiCl 2 ⋅ 6H O at 700 °C in an inert gas atmosphere. Elemental nickel obtained from decomposing served catalyst to trigger the local formation graphitic carbon. In second step, residual was removed by washing aqueous HCl. By replacing with anhydrous , we carbide‐derived carbon...
Abstract Transition metal dichalcogenides are attractive two‐dimensional electrode materials for electrochemical energy storage devices due to their high reversible charge capacity. Hybridization of these with carbon promises enhanced performance by facilitating the access reactive sites and extended mechanical stabilization. Herein, we introduce a NbS 2 /C hybrid material exhibiting gyroidal microstructure synthesized through macromolecular co‐assembly tailored block copolymer an...
This work demonstrates that the solvothermal synthesis of nanocrystalline CuInS2 thin films using amino acid l-cysteine as sulfur source is facile and robust against variation reaction time temperature. Synthesis was carried out in a range 3–48 h (at 150 °C) temperature 100–190 °C (for 18 h). It found at least 6 140 needed to produce pure proven by X-ray electron diffraction, high-resolution transmission microscopy, energy-dispersive spectroscopy. Using UV-vis spectroscopy, good absorption...
This work presents the synthesis of MoO2/MoS2 core/shell nanoparticles within a carbon nanotube network and their detailed electron microscopy investigation in up to three dimensions. The triple-hybrid material was prepared by atomic layer deposition molybdenum oxide onto networks, followed annealing sulfur-containing gas atmosphere. High-resolution transmission together with diffraction, supported chemical analysis via energy dispersive X-ray loss spectroscopy, gave proof MoO2 core covered...

Single nanowires and networks are considered as promising candidates for miniaturized memristive devices brain-inspired systems. Moreover, single crystalline nanostructures useful model systems to gain a deeper understanding in the involved switching mechanism of investigated material. Here, we report on hydrothermally grown Nb3O7(OH) showing complementary resistive (CRS) behavior. The CRS characteristics can be related an oxygen vacancy migration at electrode/metal hydroxide interface....
In this work correlations between thin film crystallinity of plasma ion assisted electron beam evaporated vanadium oxide (VOx) and fluctuations the deposition parameters during growth process could be observed by in situ monitoring conditions microscopy studies. presented case, unintentional gas flow at source caused inhomogeneous melting target material lead to an increase discharge current therefore a decrease oxygen source, resulting formation highly crystalline bands due temporary energy...
