In this article, thermal stability, viscosity, density and surface tension of graphene nano-platelet dispersed in sunflower oil are experimentally determined by varying the concentration (0.1-1.1 wt.%) temperature (40-100?C). The SEM micrograph EDS spectra used to characterize graphene. Nanofluids prepared ultrasonication technique (two-step method) maximum stability about 280?C is achieved at ...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

objectives: platelets are anucleated fragments derived from megakaryocytes. it has been demonstrated that platelets play a role in hemostasis and innate immunity. in addition, platelets have a cd40 ligand which is an important molecular marker in motivating immune cells. thus, platelets also have a role in adaptive immunity as seen by their ability to activate b cells. since human platelet micr...

The control of complex nanostructures is one the most promising strategy for designing tailored property materials. Ti2AlC, as nanolayered ternary materials combining both ceramics and metals properties, could efficiently reinforce metal matrix composite by its decomposition into nano-Ti2C particles. However, comprehensive description diffusion mechanisms Cu element Ti2AlC during has not yet be...

Abstract The mechanical properties of carbon fiber-reinforced epoxy composites were identified by adding carbon-based nano-reinforcements, such as multi-wall nanotubes (CNTs) and graphene platelets (GP), into the matrix conducting suitable experiments. main focus this study is to compare tensile modulus, strength, flexural thermal conductivity with nanoparticle reinforcement. results revealed t...

Electric surface properties of biomaterials, playing key role to various biointerfacial interactions, were related to hemocompatibility and biosensing phenomena. In this study, the examination of surface electric properties of amorphous hydrogenated carbon thin films (a-C:H) was carried out by means of electrostatic force microscope (EFM) and observation of differences in spatial charge distrib...

Idiopathic thrombocytopenia purpura (ITP) is an autoimmune disorder characterized by isolated thrombocytopenia and mucocutaneous bleeding. The former has a primary role in the diagnosis and treatment of ITP. One of the leading causes of miscounted platelets in patients who suffer from ITP is giant platelets which may indicate factitiously a severe false thrombocytopenia. Here, a case of macroth...

Catalytically grown carbon nanofibers (CNF) are a newly developed type of material produced from the decomposition of selected carbon-containing gases over metal particles. These materials consist of nano-sized graphite platelets separated a distance of at least 0.335 nm and stacked in various orientations with respect to the fiber axis. Such an arrangement results in a unique structure that is...

Outstanding mechanical properties of biological multilayered materials are strongly influenced by nanoscale features in their structure. In this study, mechanical behaviour and toughening mechanisms of abalone nacre-inspired multilayered materials are explored. In nacre's structure, the organic matrix, pillars and the roughness of the aragonite platelets play important roles in its overall mech...
