The lateral dimensions of CdSe nanoplatelets have a strong and unique influence on their opto-electronic properties, with sizes that can be tuned from the weak to the strong exciton confinement regime. There are state-of-the-art reports on several nanoplatelet syntheses; however, at present only the thickness is well-controlled. We demonstrate here that we can achieve a control over the aspect ...

The aim of the present work is to introduce a high performance cathode for magnesium-ion batteries. A simple ball mill process is employed to synthesize (V2O5)1−x (Graphene Nanoplatelets (GNP))x nanocomposite, (where x = 0, 5, 10, 15, 20 and 25 wt.% GNP). The synthesized samples are characterized using scanning electron microscope (SEM), X-ray diffraction (XRD) technique, impedance spectroscopy...

Ultra-high molecular weight polyethylene (UHMWPE) is a relevant thermoplastic in industry and well-proven standard biomaterial joint replacements. To enhance its tribological properties while preserving bulk ones, composite coatings on UHMWPE substrate were prepared using non-functionalised graphene nanoplatelet (GNP) at reinforcement concentration of 0.1–5 wt% two mechanical mixing techniques ...

An activated carbon nanofiber (CNF) is prepared with incorporated Fe-N-doped graphene nanoplatelets (Fe@NGnPs), via a novel and simple synthesis approach. The activated CNF-Fe@NGnP catalysts exhibit substantially improved activity for the oxygen reduction reaction compared to those of commercial carbon blacks and Pt/carbon catalysts.

Graphene nanoplatelets (GNPs) are added as reinforcement to ultrahigh molecular weight polyethylene (UHMWPE) with an intended application for orthopedic implants. Electrostatic spraying is established as a potential fabrication method for synthesizing large-scale UHMWPE-GNP composite films. At a low concentration of 0.1 wt % GNP, the composite film shows highest improvement in fracture toughnes...

In this work, graphene nanoplatelets (GNPs) were dispersed uniformly in aqueous solution using methylcellulose (MC) as a dispersing agent via ultrasonic processing. Homogenous GNP suspensions were incorporated into the cement matrix to investigate the effect of GNPs on the mechanical behavior of cement paste. The optimum concentration ratio of GNPs to MC was confirmed as 1:7 by ultraviolet visi...

Ethylene-octene copolymer (EOC) with a loading level of 20 wt%, maleated EOC (EOC-g-MA) 3 wt% and graphene nanoplatelets (GnPs) at four different levels, i.e., 5 10 15 were added to nylon 6 prepare nanocomposites using twin-screw extruder high shear rate screw running 300 rpm. Increased stiffness was observed the addition GnPs while tensile strength only slightly influenced. Addition into 6/EOC...
