quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...

    Electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. An electro-active redox molecule comprises the main part of the electrochemical-based sensors. Ferrocene is one of the most popular redox molecule used in biosensor fabrication. But, instability of ferrocenium ion in strong nucleophilic reagents...

Vanadium pentoxide (V2O5)-anchored single-walled carbon nanotube (SWCNT) composites have been developed through a simple sol–gel process, followed by hydrothermal treatment. The resulting material is suitable for use in flexible ultra-high capacity electrode applications lithium-ion batteries. unique combination of V2O5 with 0.2 wt.% SWCNT offers highly conductive three-dimensional network. Thi...

Transition metal oxides have a great potential in sodium-ion capacitors (SICs) due to their pronouncedly higher capacity and low cost. However, poor conductivity fragile structure hinder development. Herein, core-shell-like nickel-cobalt oxysulfide (NCOS) nanowires are synthesized demonstrated as an advanced SICs anode. The bimetallic with multiple cation valence can promote the sodium ion adso...

The emerging energy demand and need to develop sustainable storage systems have drawn extensive attention fundamental applied research. Anion redox processes were proposed in cathodic materials addition traditional transition metal boost the specific capacity electrochemical performance. Alternatively, copper nitroprusside (CuNP) features an electroactive nitrosyl ligand alongside two structura...

Thermochemical splitting of CO2 and H2O via two-step metal oxide redox cycles offers a promising approach to produce solar fuels. Perovskite-type oxides with the general formula ABO3 have recently gained attention as an attractive material alternative state-of-the-art ceria, due their high structural thermodynamic tunability. A novel Ce-substituted lanthanum strontium manganite perovskite-oxide...

The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

A vertex subset X of a graph G is said to be cyclable in G if there is a cycle in G containing all vertices of X. Ore [6] showed that the vertex set of G with cardinality n ≥ 3 is cyclable (i.e. G is hamiltonian) if the degree sum of any pair of nonadjacent vertices in G is at least n. Shi [8] and Ota [7] respectively generalized Ore’s result by considering the cyclability of any vertex subset ...

A novel chemical tethering strategy is shown to anchor polysulfides during lithium–sulfur battery cycling, resulting in high capacity and cyclability.
