Hydrophobicity properties of graphite and green synthesized graphene (gsG) from exfoliated graphite/GO towards polymer membrane characteristic and properties at different weight percentage concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. PSf/graphite and PSf/gsG membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed...

Galectin-3 (Gal-3) is a β-galactosidase binding protein that modulates various cellular processes including cell adhesion, and metastasis. We evaluated the tumor targeting and imaging properties of a galectin-3 binding peptide originally selected from bacteriophage display, in a mouse model of human breast carcinoma expressing galectin-3. A galectin-3 binding peptide, ANTPCGPYTHDCPVKR, was synt...

we describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. we present a new method for computing, electronic transport wave function and greens function of the disordered graphene. in this method, based on the small rectangular approximation, break up the potential barriers in to small parts. then using the f...

BACKGROUND Graphene is the 2D form of carbon that exists as a single layer of atoms arranged in a honeycomb lattice and has attracted great interest in the last decade in view of its physical, chemical, electrical, elastic, thermal, and biocompatible properties. The objective of this study was to synthesize an environmentally friendly and simple methodology for the preparation of graphene using...

BACKGROUND Graphene is a single-atom thick, two-dimensional sheet of hexagonally arranged carbon atoms isolated from its three-dimensional parent material, graphite. One of the most common methods for preparation of graphene is chemical exfoliation of graphite using powerful oxidizing agents. Generally, graphene is synthesized through deoxygenation of graphene oxide (GO) by using hydrazine, whi...

Objective(s): Graphene as two-dimensional (2D) materials have attracted wide attention in different fields such as biomedical imaging. Ultra-small graphene nano-sheets (UGNSs) have been designated as low dimensional graphene sheets with lateral dimensions less than few nanometres (≤ 500 nm) in one, two or few layers. Several studies have proven that the process of acidic exfoliation and oxidati...
