Graphene oxide (GO) flakes of different sizes were prepared and dispersed in isotropic and nematic (anisotropic) fluid media. The dielectric relaxation behaviour of GO-dispersions was examined for a wide temperature (25-60 (o)C) and frequency range (100 Hz-2 MHz). The mixtures containing GO flakes exhibited varying dielectric relaxation processes, depending on the size of the flakes and the ela...

Microbial fuel cell (MFC) converts the organic compounds to electricity. The higher cost of the cathode catalyst for oxygen reduction reaction (ORR) is one of the major limitations in the technology. Therefore, the study endeavored to introduce a novel cathode catalyst i.e. porous Co3O4 flakes for ORR in MFCs. The flakes exhibited the micropore surface area of 1.0372 m2/g. The MFC with cobalt o...

Graphene-based nano-technology is the future of biomedical devices including biosensors and, hence, it essential to unravel interaction graphene oxide (GO) with cellular membrane. Here, structural reorganization lipid molecules, which are building blocks a membrane, has been demonstrated in presence GO flakes. The membrane mimicked by forming stack bilayers zwitterionic phospholipid 1,2-dipalmi...

Abstract:transition and heat affected zones formed during surface remelting (in order to improve wear resistance) with TIGprocess has been investigated. Relationship between various TIG parameters and thickness of remelted and heataffected zones revealed that a high concentrated heat energy is imposed by TIG process which makes it a proper optionfor focused surface treatment. Based on microstru...

Background and Objectives: Nowadays corn flakes are the most common form of breakfast cereals however, their vitamins are declined during the baking process. In this research, production of fortified corn flakes by Lactobacillus plantarum and L. reuteri, as well as incorporation of oat and malt fiber as prebiotics have been studied. Materials and Methods: Plackett-Burman statistical design was...

Abstract Orthopedic implant coatings with optimized surface topography and chemistry can achieve favorable osteogenesis inflammatory responses. In this work, to take advantage of micro/nano-topography nutrient element Mg, atmosphere plasma spray hydrothermal treatment were employed fabricate two kinds Mg-incorporated micro/nano-topographical calcium silicate 0.9 15.7 wt% Mg content (Mg1-CS Mg2-...

Supercapacitors with holey graphitic carbon nano-flakes (HGCNF) capable of demonstrating large specific capacitance (SC) have been developed for the first time. The unique approach applying an additional conducting layer fabric (CF) coated HGCNF at both half-cells provides a significant enhancement in SC, from 323 to 1142 F g?1, half cell and 8 487 g?1 symmetric supercapacitor, when architectur...
