Facile synthesis of 4,4′-diaminostilbene-2,2′-disulfonic-acid-grafted reduced graphene oxide and its application as a high-performance asymmetric supercapacitor
TL;DR: In this paper, a novel 4,4′-diaminostilbene-2,2′-disulfonic acid (DASDSA)-functionalized reduced graphene oxide (DasDSA-rGO) was prepared via simple refluxing method involving GO and DSA in the presence of ammonia solution followed by reduction with hydrazine hydrate FTIR spectroscopy, Raman scattering, X-ray photoelectron spectroscope (XPS), and XRD analyses confirmed the successful functionalization and reduction of GO in DAS
Facile Method for the Preparation of Water Dispersible Graphene using Sulfonated Poly(ether–ether–ketone) and Its Application as Energy Storage Materials
TL;DR: The SPEEK-modified graphene (SPG) forms an aqueous dispersion that is stable for more than six months and obeys Beer's law and shows good electrochemical cyclic stability during cyclic voltammetry and charge/discharge process when used as a supercapacitor electrode.
Tunable construction of FexCo3-xSe4 nanostructures as advanced electrode for boosting capacity and energy density
TL;DR: In this article, a novel strategy is established to rational design of hierarchical iron cobalt selenide (FexCo3-xSe4) with tunable nanostructure and morphology by adjusting the stoichiometric ration of Fe: Co in order to enhance the energy density of SCs.

TL;DR: Direct fabrication of large‐sized, flexible, alloying‐type tin antimonide negatrodes for commercial sodium‐ion pouch cell battery using a simple template‐free electroplating protocol.
Optimization of CdSe nanocrystals synthesis with a microfluidic reactor and development of combinatorial synthesis process for industrial production
TL;DR: In this paper, a lab scale microfluidic reactor with computer-controlled programmable isocratic pumps and online detectors was employed to synthesize CdSe nanocrystal and three reaction parameters, viz. reaction time, the [Cd]/[Se] molar concentration ratio, and the precursor concentrations, were optimized for optical characteristics, the particle diameter, and product yield.
