“…According to Youn et al [51] , the MoS 2 /WS 2 -rGO composites were fabricated by an ultrafast hybrid microwave annealing method. Xiao et al [50] reported that the binder-free CuS, NiS/Ni 3 S 2 , FeS 2 and Co 9 S 8 electrodes with various morphologies were in situ synthesized on the according metal foils in the presentence of sulfur by a simple microwave irradiation approach. In the paper of our group, the CuS/graphene (CuS-G) composite was fabricated by one-pot microwave irradiation method under ambient conditions using a domestic microwave oven ( Fig.…”

“…From an experimental point of view, transition metal sulfides have proven to be useful in a variety of fields including biological chemistry, 1 catalysis, 2 and electrochemistry. 3 From the computational side, the apparently simple FeS diatomic molecule has been giving nightmares to computational chemists. The challenging features of the electronic structure of FeS originate from the energetic proximity of two electronic states 5 ∆: σ 2 π 4 σ 2 δ 3 σ 1 π 2 , 5 Σ + : σ 2 π 4 σ 2 δ 2 σ 2 π 2 , with same multiplicity that compete for being the ground state.…”

In diffusion Monte Carlo (DMC) methods, the nodes (or zeroes) of the trial wave function dictate the magnitude of the fixed-node (FN) error. In standard DMC implementations, the nodes are optimized by stochastically optimizing a short multideterminant expansion in the presence of an explicitly correlated Jastrow factor. Here, following a recent proposal, we pursue a different route and consider the nodes of selected configuration interaction (sCI) expansions built with the CIPSI (Configuration Interaction using a Perturbative Selection made Iteratively) algorithm. By increasing the size of the sCI expansion, these nodes can be systematically and deterministically improved. The present methodology is used to investigate the properties of the transition metal sulfide molecule FeS. This apparently simple molecule has been shown to be particularly challenging for electronic structure theory methods due to the proximity of two low-energy quintet electronic states of different spatial symmetry and the difficulty to treat them on equal footing from a one-electron basis set point of view. In particular, we show that, at the triple-ζ basis set level, all sCI results-including those extrapolated at the full CI (FCI) limit-disagree with experiment, yielding an electronic ground state of Σ symmetry. Performing FN-DMC simulation with sCI nodes, we show that the correct Δ ground state is obtained if sufficiently large expansions are used. Moreover, we show that one can systematically get accurate potential energy surfaces and reproduce the experimental dissociation energy as well as other spectroscopic constants.

“…Thus far, many studies have been devoted to the synthesis of 1-3D structured CuS and Cu 2 S electrodes by hydrothermal (Tao et al, 2014), solvothermal (Han et al, 2011;Liu and Xue, 2011), microwave (Xiao et al, 2016;Yuan et al, 2016;Wang et al, 2019), spray pyrolysis (Madarasz et al, 2001;Kalimuldina and Taniguchi, 2016a,b), and other methods. However, only a few have focused on the preparation of freestanding 3D structured Cu x S electrodes (Ni et al, 2013;Tang et al, 2017).…”

Copper sulfides (Cu x S) with different stoichiometry are considered as prospective cathode materials for lithium batteries owing to their large energy storage capability. In this work, three-dimensional Cu x S cathodes were synthesized via introducing commercially available copper foam into the solution of dimethyl sulfoxide (DMSO) and sulfur powder. The synthesis procedures were straightforward and ultrafast and did not require additional reagents, high temperature, or long processing time and can be considered as a facile one-step method. Copper sulfide materials with different stoichiometry (x = 1.8, 1.96) were obtained by changing the temperature and the residence time of the copper foam in the DMSO solution. The effects of the temperature and time on phase and morphology of Cu x S were characterized by X-ray diffraction and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy. Electrochemical tests resulted in a stable cyclability of Cu 1. 8 S cathode with 100% Coulombic efficiency and capacity of approximately 250 mAh g −1 .
