Polypropylene has been widely used as dielectric material in organic thin-film capacitors due to their high breakdown strength, low loss and self-healing capability. However, polypropylene’s energy density is relatively low. Increasing the of polypropylene by adding materials with a constant commonly used. Still, it often leads an increase loss, lower strength other shortcomings. In this study,...

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...

For a wide range of applications of graphene suspensions, a thorough understanding of their rheological properties is crucial. We probe the microstructure of dense suspensions of micron-sized, few-layer, defect-free graphene platelets by measuring their viscoelastic properties at various concentrations up to 39 mg ml(-1). We propose a model to relate the yield strain to the mesh size of the mic...

because of production process and constrains conditions, circular graphene sheet may be opposed to structural defect and pin hole, respectively. some of the defects and pin hole on a circular graphene sheet can be considered as an eccentric hole on the sheet. hence, analyzing behavior of circular graphene sheet with an eccentric hole is important. free vibration of an eccentric annular graphene...

The primary resonance and nonlinear vibrations of the functionally graded graphene platelet (FGGP)-reinforced rotating pretwisted composite blade under combined external multiple parametric excitations are investigated with three different distribution patterns. FGGP-reinforced is simplified to cantilever plate reinforced by platelet. It novel simplify leakage airflow in tip clearance non-unifo...

background: platelets rapidly lose their qualities usually after 5 day of storage. different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. the purpose of this study was to demonstrate if platelet factor 3 (pf3) assay could be an indicator of storage lesion and provide ...

C arbon, a vital element in our daily lives, is still fascinating us at the nanoscale. In PNAS, Geng et al. (1) manage to synthesize ordered arrays of atom-thick hexagonal microplatelets consisting of sp hybridized carbon. Since the discovery of C60 (Buckminsterfullerene; an icosahedral carbon cage molecules with diameter of approximately 0.7 nm) (2), carbon nanoscience emerged, and it was witn...

background: immune thrombocytopenia is a hematologic disorder characterized by low platelet count and variable bleeding manifestations due to immune-mediated platelet destruction and/or suppression of platelet production. this study was performed to evaluate characteristics and clinical presentations of adult patients with immune thrombocytopenia and to explore the clinical value of platelet an...

This work presents a novel computational approach, the DSC regularized Dirac-delta method, for vibration analysis of functionally graded graphene-platelet reinforced (FG-GPLR) porous beams resting on Winkler–Pasternak elastic foundation under moving load. Based Timoshenko beam theory, energy functional model is represented by newly constructed basis function and minimized variational principle....

blood transfusion centers are under considerable pressure to produce platelet concentrates with a shelf life limit of 3 to 5 days. many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. in this article infusible platelet membrane will be explained as a platelet substitute versus conventional liquid-stor...
