A classification SAR approach for the toxicity of metal and oxide nanoparticles, towards various cells organisms. The analysis revealed key nanoparticle properties that induce toxicity.

The influence of non-uniform electric filed on Fe3O4-Ethylene glycol nanofluid hydrothermal treatment in an enclosure with sinusoidal upper and moving lower walls is investigated in this study. Control Volume based Finite Element Method (CVFEM) is utilized to simulate in the presented model. Numerical investigation are conducted for the sundry parameters such as Reynolds number; nanoparticle vo...

We introduce a class of shape-invariant partially coherent beams with a moving guiding center which we term self-steering partially coherent beams. The guiding center of each such beam evolves along a straight line trajectory which can be engineered to make any angle with the x-axis. We show that the straight line trajectory of the guiding center is the only option in free space due to the line...

Manipulation of nanoparticles with the scanning force microscope (SFM) has been limited until now to clearing areas on a surface or to moving single particles sequentially to create two-dimensional patterns. The research reported here uses a previously described setup for nanomanipulation with the SFM to (i) build a simple three-dimensional pyramidal structure by pushing a nanoparticle on top o...

Oxygen-deficient titania (TiO2) nanoparticle photocatalysts were synthesized using a flame synthesis method. The degree of oxygen deficiency in the TiO2 particles could be changed by moving position quenching N2 gas ring with respect to reduce concentration flame. Photocatalytic property evaluation revealed that produced had better photocatalytic performance visible light region (wavelength λ >...

A numerical study of boundary-layer flow past on a moving flat plate in nanofluid with variable wall temperature and viscous dissipation is presented. The PDE containing model for phenomena are transformed to ODE the aid appropriate similarity transformations. equations then solved numerically by using built-in bvp4c scheme MATLAB. After validation scheme, solutions determined nanoparticle conc...

This work presents selected results of an EPSRC–funded project investigating the dispersion of nanoparticles in the wake of moving vehicles. The aims were to study the changes in particle number distribution (PND) due to the competing effects of dilution and transformation processes (e.g. coagulation, nucleation, condensation) over the travel time from tailpipe to roadside, and to model the fat...
