In this work, we study the vibration and bending response of functionally graded graphene platelets reinforced composite (FG-GPLRC) rectangular plates embedded on different substrates thermal conditions. The governing equations problem along with boundary conditions are determined by employing minimum total potential energy Hamilton’s principle, within a higher-order shear deformation theoretic...

Cu/Ti3SiC2/C/BN/GNPs nanocomposites were prepared by vacuum hot-pressing (HP) sintering and hot isostatic pressing (HIP) sintering methods. Microstructures, mechanical and tribological properties of Cu/Ti3SiC2/C/BN/GNPs nanocomposites were investigated. Microstructures were examined by optical microscopy (OM), X-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical properties...

A platinum free counter electrode for dye sensitized solar cells was developed using graphene platelets (GP) supported nickel nanoparticles (NPs) as the active catalyst. Few layered GP were prepared by chemical oxidation of graphite powders followed by thermal exfoliation and reduction. The nanoparticles of nickel were deposited directly onto the platelets by pulsed laser ablation. The composit...

background: the present study evaluated treatment outcomes and the treatment indexes among glanzmann’s patients in mofid children’s hospital, tehran, iran. patients and methods: a retrospective cross-sectional study was performed to evaluate the treatment protocols on 15 glanzmann’s patients with bleeding therapeutic records in mofid children’s hospital, tehran, iran, from 2006 to 2011. results...

A “stage-1” intercalated film has been made by the ion exchange of pyrrolidinium-functionalized C60 (C60(Py)n+) into centimeter-wide, micrometer-thick air-dried graphene oxide (G-O) films composed tens thousands layers stacked/overlapping G-O platelets, denoted [C60(Py)n+]G-O films. Spontaneous intercalation one layer C60(Py)n+ between adjacent expands interlayer spacing from 0.74 nm to 1.46 nm...

Graphene, after its first production in 2004 have received lots of attentions from researchers because of its unique properties. High mobility, high sensitivity, high selectivity and high surface area make graphene excellent choice for bio application. One of promising graphene base device that has amazingly high sensitivity is graphene field-effect transistor (GFET). This review selectively su...
