MHD boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. A system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order Rung...

The main objective of current study is investigation on thermo-hydraulic behavior nanofluids in a sinusoidal wavy channel as novel geometry under influences thermophoresis and Brownian motion. Differential quadrature method optimal homotopy asymptotic scheme have been employed to solve the momentum, continuity, energy nanoparticle fraction equations. validity proposed approaches evaluated by co...

the effect of a transverse magnetic field on the boundary layer flow and heat transfer of anisothermal stretching cylinder is analyzed. the governing partial differential equations for themagnetohydrodynamic, temperature, and concentration boundary layers are transformed into a setof ordinary differential equations using similarity transformations. the obtained ordinarydifferential equations ar...

the falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. this phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. in this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...

A novel DNA molecule stretching technique is developed and tested herein. Through a heated converging-diverging microchannel, thermal convection and thermophoresis induced by regional heating are shown to significantly elongate single DNA molecules; they are visualized via a confocal laser scanning microscopy. In addition, electrophoretic stretching is also implemented to examine the hybrid eff...

Here we report a thermodynamic analysis of biomolecular interactions using MicroScale Thermophoresis (MST). Using DNA hybridization with fluorescently labeled oligonucleotides as a well-characterized model system, we monitor the shift in the dissociation (Kd) constant of the interaction over a range of temperatures and calculate the free enthalpy (ΔH) and entropy (ΔS) for the hybridization reac...
