Experiments were carried out in a water-filled elongated cup of “kitchen scale,” where motion was created by rotating disk with various micro- and nano-roughness the top cup. The obtained results have shown that for some patterns nanostructures, there is noticeable growth vortex, generated disk, while other roughnesses do not make visible changes flow structure. are interest assessing efficienc...

The sol-gel method was used to make nano-TiO2 and five Chinese herbal medicines of Sophora flavescens Alt., Hypericum perforatum L., Cnidium monnieri (L.) Cuss., Kochia scoparia (L.), Zanthoxylum bungeanum Maxim. prepare kinds nano-TiO2-Chinese medicine composite anti-degradative wood. Populus tomentosa Carr chosen as the wood sample. Indoor decay resistance test results showed that weight gain...

The electrostatic doping technique has a remarkable ability to reduce random dopant fluctuations (RDFs), fabrication complexity and high thermal budget requirement in the process of nano-scale devices. In this paper, for first time it been propose simulated junction-free electrostatically doped tunnel field-effect transistor (JF-ED-TFET) based biosensor label-free biosensing applications. diele...

The structural color based on the Fabry–Perot (F–P) resonator has been extensively applied lithography-free and tunable displays. Conventional F–P cavity-based technology exhibits a wide half maximum full width (fwhm), thus causing low saturation. In this study, Sc0.2Sb2Te3(SST) structure of multi-order cavity resonance was proposed to obtain high-saturation colors. surface absorber coated with...

magnetic field effect on unsteady natural convection heat transfer of cu–water nanofluid in a square porous cavity was studied numerically in here. at first, initial temprature of the cavity was and vertical walls were at temprature . suddenly the right wall's tamprature was changed to and the horizontal walls were adiabatic. the effective parameters in this study were ra , ha, and . which appe...

we propose a new generation of unbiased (bias-free) antenna-less cw thz photomixer emitters array made of asymmetric msm gratings with subwavelength pitch, operating in optical near-field regime. we take advantage of the size effects in near-field optics and electrostatics to demonstrate the possibility of enhancing the thz power by four orders of magnitude, as compared with a similar array of ...
