Investigating the effect of chemical functionalization on MWCNTs' electronic properties, and their influence course results electrophoretic deposition process.

   In chiral and non-chiral electrophoretic resolution of basic drugs, adsorption of analytes to negatively charged capillary wall could lead to poor repeatability of migration time and peak area. In addition, chiral resolutions of basic drugs are commonly performed in low pH buffers. Therefore, longer analysis time due to suppression of electroosmotic flow (EOF) is another dilemma. In this wor...

nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

Advances in carbon nanotube (CNT) based composites over the past decade have demonstrated broad potential of utilizing them as multifunctional sensors because their unique electrical properties. This article studies thermoresistive behavior two-component (CNT-epoxy) nanocomposites and hierarchical (CNT-fiber-epoxy) multiscale using situ resistance measurements during thermal cycling from 25 to ...

Abstract In this study, molybdenum disulfide nanosheets, bioactive hydroxyapatite particles of two types in various amounts, and PEEK 704 microparticles were electrophoretically co-deposited to fabricate multicomponent coatings on Ti-13Nb-13Zr alloy substrates. A mixture pure ethanol cationic chitosan polyelectrolyte was used as a dispersion medium. The kinetics mechanism deposition investigate...

Abstract Coating laser-patterned stainless-steel surfaces with carbon nanotubes (CNT) or onions (CO) forms a tribological system that provides effective solid lubrication. Lubricant retention represents the fundamental mechanism of this system, as storing particles inside pattern prevents lubricant depletion in contact area. In previous works, we used direct laser interference patterning to cre...

Micro/nanomotors are capable of a wide variety tasks related, i.e., to biomedical or environmental applications. Light-driven semiconductor-based micromotors especially appealing, as they can split surrounding water via light irradiation, and therefore, move infinitely. However, their motion is typically limited in-plane with four degrees freedom (4DoF) even pseudo-1D 2DoF. Herein, magnetically...

the aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgelcoatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 n h2so4environment. the influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and20, on the coating quality and its corrosion prevention performance was investigated. differentialtherma...
