The viscosity of polydispersed graphene nanosheet (5 nm–1.5 lm) suspensions (GNS) and its behavior with temperature and concentration have been experimentally determined. A physical mechanism for the enhanced viscosity over the base fluids has been proposed for the polydispersed GNSs. Experimental data reveal that enhancement of viscosity for GNSs lies in between those of carbon nanotube suspen...

adsorption of co2 on the surface of single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (swcnts) were studied through using density functional theory (dft) calculations. optimizations of geometric were performed at the b3pw91 level of 6-311++g** method standard basis set using gaussian 03 package of program [1]. structural models were optimized and adsorption energies, band gap, charge...

in this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (bnnt) has been investigated by quantum calculations. in order to find the preferred adsorption site, different positions and orientations were considered. the impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...

Two different schemes to switch-off unused circuit blocks (ZigZag-cut-off scheme' and n-/p-block MTCMOS cut-off schemê '̂ ''̂ '̂ '̂ are examined in deep-submicron technologies by analytical investigation and simulation. The theoretical basis of the ZigZag-scheme is given and particular design constraints are discussed. It is shown that the power-saving benefits of the ZigZag-scheme are critically d...

This paper studies an unmanned aerial vehicle (UAV)-enabled wireless sensor network, in which one UAV flies the sky to collect data transmitted from a set of ground nodes (GNs) via distributed beamforming. We consider two scenarios with delay-tolerant and delay-sensitive applications, GNs send common/shared messages adaptive- fixed-rate transmissions, respectively. For scenarios, we aim maximiz...

The emission of gravitational waves (GWs) during single-single close encounters in galactic nuclei (GNs) leads to the formation and rapid merger highly eccentric stellar-mass black hole (BH) binaries. distinct distribution physical parameters makes it possible statistically distinguish this source population from others. Previous studies determined expected binary parameter for single GNs. Here...

The extreme extinction ($A_V\sim30$\,mag) and its variation on arc-second scales towards the Galactic centre hamper study of stars. Their analysis is restricted to near infrared (NIR) regime, where curve can be approximated by a broken power law. Therefore, correcting for fundamental analyse structure stellar population central regions our Galaxy. We aim to, (1) discuss different strategies de-...

In this work, we optimize the 3D trajectory of an unmanned aerial vehicle (UAV)-based portable access point (PAP) that provides wireless services to a set ground nodes (GNs). Moreover, as per Peukert effect, consider pragmatic non-linear battery discharge for UAV’s battery. Thus, formulate problem in novel manner represents maximization fairness-based energy efficiency metric and is name...
