Foamlike 3D Graphene Coatings for Cooling Systems Involving Phase Change

Boiling is an efficient heat-transfer mechanism because of the utilization of latent heat of vaporization and has the potential to be used for cooling high-power electronic devices. Surface enhancement is one of the widely used techniques for heat-transfer augmentation in boiling systems. Here, an experimental investigation was conducted on chemical vapor deposition-grown three-dimensional (3D) foamlike graphene-coated silicon surfaces to investigate the effect of pore structures on pool boiling heat transfer and corresponding heat-transfer enhancement mechanisms. 3D graphene-coated samples with four graphene thicknesses were utilized along with a plain surface to investigate boiling heat-transfer characteristics and enhancement mechanisms...

Superbat: Battery like supercapacitor utilized by graphene foam and zinc oxide (ZnO) electrodes induced by structural defects

The current work presents a hybrid type of energy storage device composed of both graphene foam and zinc oxide electrodes which exhibit both electrochemical performances of supercapacitor with relatively higher powder density and battery with relatively higher energy density as compared to each individual component as single devices. And, they correlate the hybrid performance to the defective structure of the electrodes. To enhance the electrochemical performance of supercapacitors it is necessary to have well-defined mass, shape and surface area of electrode materials... Read More

Investigation of MnO2 nanoparticles-anchored 3D-graphene foam composites (3DGF-MnO2) as an adsorbent for strontium using the central composite design (CCD) method

Strontium-90 is the one of the dangerous fission products generated during electricity production in nuclear reactors. Therefore, separation of this radionuclide from contaminated water is an important step to safeguard human health and minimize the impact on the environment. In this research, adsorption performance of strontium ions onto 3DGF-MnO2 composites investigated. Three-dimensional graphene foam (3DGF) was prepared by chemical vapor deposition (CVD) method, then it was doped with MnO2 nanoparticles by hydrothermal method. 3DGF-MnO2 composites were characterized by Raman and XRD to reveal its chemical and structural properties...
