Adsorption Properties of Tetracycline onto Graphene Oxide: Equilibrium, Kinetic and Thermodynamic Studies

Graphene oxide (GO) nanoparticle is a high potential effective absorbent. Tetracycline (TC) is a broad-spectrum antibiotic produced, indicated for use against many bacterial infections. In the present research, a systematic study of the adsorption and release process of tetracycline on GO was performed by varying pH, sorption time and temperature. The results of our studies showed that tetracyc...

3D Finite Element Simulation of Graphene Nano-Electro-Mechanical Switches

In this paper, we report the finite element method (FEM) simulation of double-clamped graphene nanoelectromechanical (NEM) switches. Pull-in and pull-out characteristics are analyzed for graphene NEM switches with different dimensions and these are consistent with the experimental results. This numerical model is used to study the scaling nature of the graphene NEM switches. We show the possibi...

Molecular Dynamics Simulation of Al Energetic Nano Cluster Impact (ECI) onto the Surface

On the atomic scale, Molecular Dynamic (MD) Simulation of Nano Al cluster impact on Al (100) substrate surface has been carried out for energies of 1-20 eV/atom to understand quantitatively the interaction mechanisms between the cluster atoms and the substrate atoms. The many body Embedded Atom Method (EAM) was used in this simulation. We investigated the maximum substrate temperature Tmax  and...

Molecular Simulation of Hydrogen Adsorption onto Single-Walled Carbon and Boron-Nitride Nano-Cones

In this paper, we have studied the hydrogen adsorption onto CNCs and BNNCs nano-cones using GCMC simulations. The effects of length and cone apex angle on adsorption property have been investigated. Our results show that with increasing the pressure and decreasing the cone length and cone apex angle except for CNC-300˚, the hydrogen adsorption onto the BNNCs and CNCs was increased. It was also ...

Nano-scale chemical imaging of a single sheet of reduced graphene oxide

Scanning transmission X-ray microscopy (STXM) has been used to chemically image single and multiple layers of a thermally reduced graphene oxide (r-GO) multi-layer sheet of the size of 1 mm and a thickness of 5 nm. The thickness of individual layers in the single sheet can be identified through quantitative analysis of STXM. The local electronic and chemical structure of interest (edge versus c...
