“…2Θ = 35.81°and 2Θ = 44.03°attributing to (200) and (220) crystal planes indicating α-MnS and �-MnS forms, respectively. Thus, these XRD peaks verified the coexistence of α-and �phases together in the MnS crystal structure [55]. Two obvious XRD peaks at 2Θ = 19.81°and 2Θ = 24.91°were also attributed to (020) and (200) crystal planes, respectively, for MnS/GO/PANI nanocomposite.…”

Herein, electrochemical tau protein immunosensor based on manganese sulfide nanoparticles/graphene oxide/polyaniline (MnS/GO/PANI) and magnetiteincorporated gold nanoparticles (AuNPs@Fe 3 O 4 ) was constructed. After the modification of the glassy carbon electrode (GCE) with MnS/GO/PANI, the immobilization and conjugation of anti-Tau capture antibody and antigen Tau protein were successfully completed on MnS/GO/ PANI/GCE, respectively. Then, the conjugation of anti-Tau secondary antibody was carried out to AuNPs@Fe 3 O 4 as signal amplification via amino-gold affinity and the eventual immunosensor was accomplished by the distinctive interactions of electrode platform and signal amplification. Final immunosensor demonstrated the quantification limit (LOQ) of 1.0 × 10 À 13 M and the detection limit (LOD) of 1.0 × 10 À 14 M.

“…This not only allows for a great amount of the electrolyte to be accessible for faster mass transfer but also promotes high mechanical flexibility. During rigorous cycling performance, the electroactive materials commonly suffer pulverization. , To mitigate this issue, the general practice is to decorate active material with a porous carbonaceous matrix (such as three-dimensional-graphene; 3DG) for better electrochemical performance. − The carbonaceous materials not only provide high conductive channels for electron movement but also simultaneously minimize unwanted accumulation of metal sulfide. − Out of the three distinct phases of MnS (α, β, and γ), the metastable γ-MnS is a layered hexagonal wurtzite structure that can promote facile intercalation of ions and thereby balance the increased valencies of Mn without hindering its structural deformation that provides a shorter diffusion length …”

In energy storage-device it is highly crucial to develop durable electrode materials having high specific capacitance and superior energy density without disturbing its inherent flexibility. Herein, we demonstrate three-dimensional graphene oxide decorated monodispersed hollow urchin γ-MnS (γ-MnS@3DG) via proficient one-step solvothermal method. The designed material delivers a remarkable capacitance of 858 F g −1 at 1 A g −1 . A flexible solid state asymmetric supercapacitor (ASCs) device assembled using surface activated carbon cloth (CC) decorated with γ-MnS@3DG as positive and three-dimension graphene on carbon cloth (3DG@CC) as negative electrode, (γ-MnS@3DG//3DG). The device delivers 26 Wh kg −1 energy density at power density 500 W kg −1 @ 1A g −1 and retains favorable energy density 17.8 Wh kg −1 at an ultrahigh power density of 1500 W kg −1 @3 A g −1 . This carbon embedded transition-metal sulfide (TMS) based ASC demonstrates eminent mechanical flexibility under rigorous bending states maintaining invariant performance.

“…In addition, at a much higher power density of 3501.5 W kg À 1 , the energy density at this time decreases to 16.63 Wh kg À 1 , which exceeds many of the previously reported values of relevant materials, as shown in Figure 5(g). [45][46][47][48][49][50][51][52][53] The CV curves of AC at various scanning rates and the GCD curves at diverse current densities are displayed in Figure S4. The semicircle shape and linear charge-discharge curves highlight the electrochemical double-layers energy storage mechanism of AC.…”

The excellent electrical conductivity of graphene is due to its highly-conjugated structures. Manipulation of the electronic and mechanical properties of graphene can be achieved by controlling the destruction of its in-sheet conjugation system. Herein, we report the preparation of CoCeS x À SA@BPMW@RGO through π-π stacking interactions at the molecular level. In this study, sodium alginate was reacted with Co 2 + and Ce 3 + , and the composite was loaded onto a graphene surface. The graphene sheets were prepared using a bi-pyrene terminated molecular wire (BPMW) to avoid re-stacking of the grapheme sheets, thereby forming nanoscale spaces between sheets. The angle between the BPMW coplanar pyrene group and the phenyl group was 33.2°, and the graphene layer is supported in an oblique direction. Finally, a three-dimensional porous composite was obtained after annealing and vulcanization. The obtained CoCeS x À SA@BPMW@RGO exhibited excellent electrical conductivity and remarkable cycle stability. When the current density was 1 A g À 1 , its specific capacitance was as high as 1004 F g À 1 . BPMW modifies graphene through the synergistic effect of π-π stacking interaction and special structure to obtain excellent electrochemical performance. Moreover, a solid-state asymmetric supercapacitor device was fabricated based on the synthesized CoCeS x À SA@BPMW@RGO hybrid, which exhibited a power density of 979 W kg À 1 at an energy density of 23.96 Wh kg À 1 .
