Nanoparticles play a major role in industrial processes and natural phenomena in a variety of fields including chemical engineering, chemistry, physics, public health and biology. Nanoparticles are suspended in fluids during production, handling, processing, and by unintentional and/or undesirable release to the environment. In many cases the suspending fluid is a gas, as for example in large s...

A long standing goal is the direct optical control of biomolecules and water for applications ranging from microfluidics over biomolecule detection to non-equilibrium biophysics. Thermal forces originating from optically applied, dynamic microscale temperature gradients have shown to possess great potential to reach this goal. It was demonstrated that laser heating by a few Kelvin can generate ...

This article addresses the steady three-dimensional flow of an Oldroyd-B nanofluid over a bidirectional stretching surface with heat generation/absorption effects. Suitable similarity transformations are employed to reduce the governing partial differential equations into coupled nonlinear ordinary differential equations. These nonlinear ordinary differential equations are then solved analytica...

This work aims at examining the thermophoresis and Brownian motion characteristics on stagnation point flow of Cross nanofluid over a permeable stretching /contracting surface. Flow equations are modelled by means Buongiorno model. The transformed non-linear fluid transport solved numerically through Runge-Kutta Fehlberg (RKF) approach. temporal stability test is executed to reveal behaviour du...

It is shown using the method of molecular dynamics that motion carbon nanoparticles (rectangular graphene flakes, spherical fullerenes size $L<10$ nm) on surface a thermalized sheet lying flat substrate can be described as particles in viscous medium with constant coefficient friction, value which depends temperature and particle size. has been there are two types effective friction: diffusi...
