Developing 'carbon lithium sulfide composite (C-Li2S)' cathode is a promising strategy for Li-S battery. Quite interestingly, when Li and S are caged in a heavily nitrogen-doped reduced graphene oxide (NDRGO) matrix derived from Tassar silk cocoon, the composite (NDRGO-Li-S) electrode behaves like a supercapacitor. In this work, we first optimized the concentrations of sulfur and then introduced molybdenum in the NDRGO matrix to develop a stable NDRGO-Mo-Li-2S (where 2 stands for 2M) composite e...

A new discrete bis-dithiolene complex, [PPh4]2[Zn(DMED)2] (1; DMED = 1,2-dicarbomethoxy-1,2-dithiolate) with sulfur-based radical character was synthesized and structurally characterized. Complex 1 is stable and exhibits a square planar geometry around the zinc metal. 1 forms nanospheres through a one-pot water-induced self-assembly in a mixture of solvents (acetonitrile–water). These nanospheres were further decorated with water-soluble carbon nanotubes (wsCNTs) through hydrogen bonding between...

A new molybdenum complex, [Et4N]2[Mo(PPh3)(mnt)2–OMo(mnt)2]·CH2Cl2·½H2O (1, mnt = maleonitrile dithiolene = S2C2(CN)2), with unique structural features was synthesized, in which the fragment {Mo(PPh3)(mnt)2–} was attached to another important {–OMo(mnt)2} moiety. The structure of 1 was formed by the association of both the oxo and desoxo motifs of the dimethylsulfoxide reductase (DMSOR) class of enzymes. This dissymmetrical binuclear complex 1 is rare, and it utilized the basic inorganic aspects...

Nitrogen-doped graphene nanosheets that are readily dispersible in water (N-wsGNS) were synthesized using lentil as a natural source of carbon and nitrogen via a simple pyrolysis and oxidation approach. The as-synthesized N-wsGNS showed remarkable fluorescence emission over the entire visible range attributed to the high degree of surface passivation due to the introduction of oxygenated functional groups and heteroatom doping. The significant perceptive of this approach is to use N-wsGNS as mul...

We have reported here the synthesis, structure and spectroscopic properties of the NiII–FeIII heterobimetallic ethene-bridged porphyrin dimer and investigate the effect upon step-wise one- and two-electron oxidations to produce a mixed-valence π–cation radical dimer and a dication diradical complex, respectively. We then investigate their electronic structure and spin coupling model and compare them with the corresponding homobimetallic analog. Detailed UV-vis-NIR, IR, and variable temperature m...

Abstract The discovery of fullerenes triggered the exploration of carbon in the nanodomain, leading to the characterization of diverse versions of nanocarbons ranging from carbon nanotubes, carbon nanoonions, carbon dots, and graphene in different shapes and sizes. The hydrophobic property of carbon in these materials has been tampered by oxidative derivatization introducing hydrophilic groups in the periphery or the surface of these nanocarbons to render these dispersible or soluble in water. S...
