Synthesis and characterization of Graphene Oxide in suspension and powder forms by chemical exfoliation method
In this study, an efficient and facile technique for preparing graphene oxide in suspension and powder forms was presented based on a modification on Hummers' method followed by an additional ultrasonic process. The method involved the provision of graphene oxide from graphite by reaction of potassium permanganate and sulfuric acid with stabilizing the medium complex. Furthermore, this study ev...

متن کاملSynthesis & Characterization of CaB4O7 Powder by Solid-State Reaction
The synthesis of calcium tetraborate was investigated in a temperature ranging from 800℃ to 900℃ using the solid-state reaction method. The synthesis was done using ammonium tetraborate tetrahydrate as the source of boron. At temperatures of 800 ℃ and 880 ℃, the mixed phases from different compounds were formed. At the optimum temperature of 840℃, the mixed phase was only composed of meta and t...
متن کاملFormation of self-inhibiting copper(II) nanoparticles in an autocatalytic Fenton-like reaction.
Cu(II)-catalysed decomposition of hydrogen peroxide at alkaline pH in the presence of etidronic acid (HEDP) showed a sigmoid kinetic profile typical of autocatalytic reactions. However, the reaction abruptly stopped well before all hydrogen peroxide had decomposed, and further addition of Cu(II) and HEDP did not restart the reaction. Results of a mechanistic study suggest that the reaction invo...
متن کاملAutocatalytic reaction-diffusion processes in restricted geometries
We study the dynamics of a system made up of particles of two different species undergoing irreversible quadratic autocatalytic reactions: A + B → 2A. We especially focus on the reaction velocity and on the average time at which the system achieves its inert state. By means of both analytical and numerical methods, we are also able to highlight the role of topology in the temporal evolution of ...
