In this paper, a numerical solution has been developed for hollow circular cylinders made up of orthotropic material which is subjected to twist using micro polar theory. The effect of twisting moment and material internal length on hollow thick-walled circular cylinder made up of micro polar orthotropic material is investigated. Finite difference method has been used to exhibit the influence o...

The hydrophobic-amphiphilic self-assembly approach has been employed to prepare molecular micro-capsules simply by cooling down an emulsion, in a hot polar solvent medium, of a melted compound having two very well-distinguished units, both with highly non-polar and hydrophobic characteristics. The resulting micro-capsules are very stable and robust both in suspension and under dry conditions. F...

This is an attempt to model an unsteady peristaltic flow of micro-polar fluid in a channel of finite length. The channel is subjected to progressive sinusoidal waves that help the walls contract and relax but not expand beyond the natural boundary. It is found that the coupling number increases pressure along the entire length of the channel, while the micro-polar parameter decreases it. The co...

Visible light communication (VLC) based on the micro emitting diode (micro-LED) has attracted increasing attention owing to its high bandwidth, low power consumption, and security. Compared with semi-polar or non-polar micro-LEDs, commercial polar micro-LED advantages of cost more mature epitaxy technique. In this study, green micro-LEDs different indium tin oxide (ITO) sizes are fabricated c-p...

In the present work a two fluid model for blood flow through abnormally constrictedhuman artery (stenosed artery) has been developed. The model consists of a core region of suspensionof all erythrocytes assumed to be micro-polar fluid so as to include the micro-structural effects inaddition to the peripheral-layer viscosity effects, and a peripheral plasma layer free from cells of anykind of Ne...

A main question for the study of collective motion in living organisms is the origin of orientational polar order, i.e., how organisms align and what are the benefits of such collective behaviour. In the case of micro-organisms swimming at a low Reynolds number, steric repulsion and long-range hydrodynamic interactions are not sufficient to explain a homogeneous polar order state in which the d...

Wurtzite ZnO hexagonal micro-pyramids, with all exposed surfaces being polar +/- (0001) and {1011} planes, have been successfully synthesized using ionic liquids as solvents.

The digested sample can either be filtered prior to analysis or cleaned and concentrated with Thermo ScientificTM SOLAμTM HRP, a highly versatile polymeric micro-scale SPE device offering both polar and non-polar retention of peptides. The ability to elute in low elution volumes reduces the risk of solubility or binding issues as an evaporation step is not required to achieve a concentration fa...
