The shell filled nano-enhanced material (NePCM). cone aspect ratio of the and were adopted as geometrical parameters. type volume fraction nanoparticles other investigated alumina, graphite oxide, silver, copper. finite element method employed to solve natural convection ...

The influence of Coriolis body force, electro-magnetohydrodynamics (EMHD) and thermal radiative heat transfer on the Casson hybrid mixed convection nanofluid driven by an exponentially accelerated plate adjacent to a porous medium in rotating system is analyzed. Hybrid (Ag- Al2O3) Al2O3nanofluids are considered with ethylene glycol (EG) base fluid. Maxwell-Garnett model has been deployed derive...

DNA microarrays have, since their introduction around 1995, gained wide use in bio-analytical chemistry. Yet the hybridization is limited by molecular diffusion, leading to overnight waiting times. During the last couple of years a large number of methods were developed to overcome this diffusion-limitation and to enhance the speed and detection limits of the microarray experiments. The generat...

Nanoparticles are of long-standing interest for the treatment of neurological diseases such as glioblastoma. Most past work focused on methods to introduce nanoparticles into the brain, suggesting that reaching the brain interstitium will be sufficient to ensure therapeutic efficacy. However, optimized nanoparticle design for drug delivery to the central nervous system is limited by our underst...

The paper deals with the use of biological life support systems, initially created for long-duration space flights [1, 2], for the solution of problems with the sustainability of metropolitan cities, which must meet the requirements of decrease of environmental load. Motivated by applications in issues of design of water purification stations for new generation of high-rise buildings ''Sky City...

We investigate experimentally the emergence of collective motion in the bulk of an active suspension of Escherichia coli bacteria. When increasing the concentration from a dilute to a semi-dilute regime, we observe a continuous crossover from a dynamical cluster regime to a regime of ‘bio-turbulence’ convection patterns. We measure a length scale characterizing the collective motion as a functi...

Abstract. In this report the development of a finite volume method for the time-accurate simulation of the temperature distribution in a premature infant inside an incubator or in an open radiant warmer is described. The real geometry of a premature infant is obtained from MRT-images. The infants thermoregulation is modelled by the so-called bio-heat-transfer-equation incorporating source terms...

Microcantilevers are finding wide applications in detecting biochemical agents. However, their usage has been limited to highly concentrated samples to ensure sufficient deposition of agents onto cantilevers. A pre-concentration or enrichment step will expand their application range to more dilute, practical samples and real-time detection. This paper reports the integration of in-situ particle...

the fluid flow and heat transfer in lid-driven enclosures filled with cu-water nanofluid is numerically investigated. the moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity field and pressure in the momentum...
