Here, for the first time, we combine GA with Co3O4 and ZnO nanoparticles (NPs) to fabricate a ternary GA/Co3O4/ZnO composite (GAC) as a potential supercapacitors candidate by using versatile approach. Zinc and cobalt ions are adsorbed on graphene oxide sheets to make a suitable initial material for mild chemical reduction method in order to make ternary GA/Co(OH)3/Zn(OH)2 composite. Heat treatment is used to convert hydroxide of Cobalt and Zinc to oxide components after freeze drying of hydrogel. GA/Co3O4 and GA/ZnO nanocomposites were simultaneously synthesized for comparison. Compared with these two binary nanocomposites, the produced ternary GA/Co3O4/ZnO composite exhibits higher specific capacitance (F/g at A/g), better rate performance and long-term cycling stability due to the porous nature of GA which can help increasing electrical conductivity and surface area of the composite electrodes. ZnO is eco-friendly and low cost compound and Co3O4 with good retention capability can enhance the specific capacitance of GA with pseudocapacitive activity and do prevention in aggregation graphene sheets in electrochemical performance.

Synthesis and nano-mechanical properties of core/shell abrasive particles used in chemical mechanical planarization (CMP)

Due to their combined advantages and multi-functions, core/shell particles of various compositions have been attracted much attention in different application including catalyst, solar cell, biotechnology and drug delivery. Recently, organic/inorganic composite abrasives with a core–shell structure applied in CMP process have attracted more attentions.

Since mechanical properties of abrasives have numerous effects on CMP efficiency, in this research we investigate nano-mechanical properties of hybrid abrasive particles comprising of PS core and SiO2 shell by means of atomic force microscopy (AFM). For this purpose, such particles with different size of core and shell will be synthesized and it’s characteristics will be investigated by SEM, TEM and AFM techniques. Nano-mechanical properties of particles will be examined by AFM and the effect of various parameters including silica shell thickness and applied force by the AFM tip on elastic properties will be studied. Furthermore, elastic behavior of such particles under applied force will be analysed using the molecular dynamics (MD) simulation method.

Graphene-Based Ultra-Lightweight Nanofluids

Carbon nanomaterials such as carbon nanotubes and more recently graphene consisting of three-dimensional (3D) interconnected micropores and mesopores have attracted attention due to their favorable properties, such as being lightweight and possessing high porosity, a large surface area, and high conductivity; Therefore, it incontestably recognized to be the best candidates for the new generation of nanofluids. In this project, ultra-lightweight nanofluids based on Colloidal Gas Aphrons (CGAs) will be prepared using porous graphene structures and their derivatives by chemical methods.

Characterization and Evaluation of Electrocatalytic Properties of the Nanostructure of Si@Au@Pt core shell

The enhance activity of core-shell structure is related with the underlying interface between the core and shell metals due to the bimetallic mechanism.Recent research showed that Au-Pt bimetallic catalyst, especially Au@Pt core-shell nano- catalysts had a promising application on reducing Pt amount in electro-catalyst, reducing CO poisoning in Pt catalyst and so on.Our objective is to synthesize a nanostructured sio2-Au–Pt on carbon support with a controlled shell thickness and improved Pt utilization by chemical reduction approach. The core-shell structure is realized via a successive reduction strategy and by carefully choosing an appropriate reducing agent.

Synthesis of Aerographene nanocomposites suitable for oil pollutants adsorption.

In recent years, removal of oil and other major organic contaminants from wastewater has been of the greatest issues in environmental remediation. One of the promising approaches is to remove by sorbent material. Studies showed that Graphene-base material can make a real breakthrough in this way. What we are going to do is the synthesis of graphene aerogel nanocomposites with enhanced adsorption capacity and structural elasticity simultaneously.

investigation of Acoustic Waves Dispersion in Aero-graphene by Molecular Dynamics Simulation

Porous materials show outstanding characteristics due to their special structures. Aerographene is one of the nanoporous materials which is recently attracted researchers’ attention. One of the useful properties of this nanomaterial is the ability to absorb waves like elastic waves and sound waves. Thus, investigating aerographene characteristics for absorbing different kinds of perturbations and waves is of paramount importance. In this project, the aero-graphene with arbitrary structural characteristics will be modeled with molecular dynamics simulations(MD) method and dispersion of acoustic waves will be studied in this nanostructure.
