For years, there has been a renewed interest in the unique focusing properties of cylindrical vector beams (CVB), i.e., beams which exhibit rotationally symmetric polarization states, and their novel imaging applications [1]. Particularly, it was found that focused CVBs can be used as versatile orientation probes for single molecules and metal nanostructures [1]. Orientation imaging of metal na...

Polytetrafluoroethylene (PTFE) is a polymeric material with excellent self-lubricating properties. In this study, in order to improve the wear resistance of PTFE, PTFE matrix was filled soft-phase polyetheretherketone (PEEK) particles and hard-phase nano-ZrO2 varying volume ratios. A linear reciprocating friction tester used test tribological properties composites. Optical microscopy (OM) scann...

We functionalized peptide nanofibers to provide a nano-scale template for the display of biomolecules and inorganic nanoparticles using metal ion coordination. Nanofibers assembled only in the presence of certain divalent metal ions, and could be readily dissolved by a metal-chelating reagent, EDTA.

A new simple and reliable method for rapid and selective extraction and determination of trace levels of Zn(II) ion is developed. Zn(II) ions are adsorbed quantitatively during passage of aqueous samples through PET-AA/AAm nano fiber modified. Almost all matrix elements were found to pass through the nano fiber to drain. Modified Poly (ethylene terephthalate)-grafted-Acrylic acid/Acryl amide Na...

We describe the nanofabrication study of self-aligned electrodes on suspended multiwalled carbon nanotube structures. When metal is deposited on a suspended multiwalled carbon nanotube structure, the nanotube acts as an evaporation mask, resulting in the formation of discontinuous electrodes. The metal deposits on the nanotubes are removed with lift-off. Using Al sacrificial layers, it was poss...

Metal oxides such as ZnO, SnO2 and W2O3 with super properties are widely used in the different fields of science and proper synthesis of these materials is of the great importance. In this work, some metal oxides with nano structures including SnO2 nanopyramids, V2O5 nanowires and hierarchical structure of SnO2 nan...

Nano-sized nickel oxide (nano-NiO) is a new nanomaterial that has shown great promise in many areas of application. Understanding its environmental fate and effects is critical for minimizing the potential environmental implications of this new material due to incidental and accidental releases in the future. In this study, we observed strong adsorption of tetracycline to nano-NiO and found tha...

nano technology has a large number of applications in different fields of science and technology. nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. the properties of nanoparticles depend largely on their synthesis procedures. there are different methods for the synthesis of nano particles using different conditions. in ...
