Graphene-Metal Oxide based Nanocomposites for Supercapacitor Applications

Selvakumar D., Nagaraju P., Jayavel R., Anna University, IN

Two dimensional graphene-based nanocomposites have been synthesized through the modified Hummer’s method and chemical reduction process. Transition metal oxides were decorated on the graphene sheets by in-situ hydrothermal method. The composites were formed with graphene [...]

Electrochemically Exfoliated Graphene: Production and High Performances.

Wang J., Institute of Coal Chemistry, Chinese Academy of Sciences, CN

I’d like to present that graphene flakes have been produced with good properties and potentially used widely through electrochemical approaches. The electrochemically exfoliated graphene-based materials exhibit high performances in thermal management, electrocatalysis, supercapacitor, batteries and [...]

Graphene based core–shell additives for increasing the thermal conductivity of epoxy nanocomposites

Eksik O., Bartolucci S.F., Gupta T., Fard H., Tasciuca T.B., Koratkar N., Istanbul Technical University, TR

We studied novel technique to enhance the thermal conductivity of epoxy nanocomposites using graphene coated poly-methyl-methacrylate (PMMA) balls. PMMA balls with a diameter in the range of 200–300 nm were synthesized using suspension polymerization. These [...]

Graphene Synthesized in the Gas Phase: Research and Applications

Dato A., Harvey Mudd College, US

Pure and highly ordered graphene can be rapidly and continuously produced through the substrate-free gas-phase synthesis method. The single-step process involves sending precursors, such as ethanol and dimethyl ether, directly into atmospheric-pressure microwave-generated argon plasmas, [...]

Transition Metal Dichalcogenides as Cell Culture Platforms

Palumbo A., Tourlomousis F., Chang R., Yang E.H., Stevens Institute of Technology, US

Transition metal dichalcogenides (TMDs), such as WS2 and MoS2, have been widely explored for their utilization as two-dimensional (2D) semiconducting nanomaterials with unique electronic, mechanical, and catalytic properties. A multitude of research has been pursued [...]

Novel Graphene Structures: Substantial Capacity Enhancement in Lithium Batteries

Paronyan T.M., Thapa A.K., Sherihy A., Jasinski J.B., Dilip Jangam S.J., University of Louisville, US

Development of high capacity rechargeable battery anode would significantly improve the advanced energy technologies and enhance the energy efficiency of many economic markets, particularly electric grid storages and renewables. Recently, major research has been directed [...]

Graphene oxide/vinyl ester resin nanocomposite: the effect of graphene oxide, curing kinetics, mechanical properties and thermal stability

Arabli V., Aghili A., Islamic Azad University, Shiraz, IR

Graphene oxide (GO) was synthesized and nanocomposite was achieved using different contents of the GO and Vinyl Ester Resin (VE). The suspension was sonicated in order to prevent the agglomeration. Non-isothermal differential scanning calorimetry (DSC) [...]

Structure determination of silicene nanoribbons on Ag(110)

Espeter P., Keutner C., Kleimeier N.F., Roese P., Shamout K., Wenzel G., Berges U., Zacharias H., Westphal C., TU Dortmund, DE

Since the discovery of graphene much interest came up in the graphene analoga from the carbon group. One of the most famous representatives is silicene. Silicene is known to crystallize in different configurations, depending on [...]

Two-Dimensional Nanoporous Silicates and Their Potential Applications

Zhong J.Q., Kestell J., Akter N., Kim T., Wang M., Lu D., Galuskina I., Stacchiola D.J., Boscoboinik J.A., Brookhaven National Laboratory, US

Ultra-thin two-dimensional inorganic nanoporous silicates have been recently synthesized. They are as thin as 0.5 nm, can be produced in the form of ordered structures or glasses and doped with other elements, such as aluminum. [...]
