The colonisation of clinical and industrial surfaces with microorganisms, including antibiotic-resistant strains, has promoted increased research into the development of effective antibacterial and antifouling coatings. This study describes the preparation of metal nitrate (Ag, Cu, Zn) doped methyltriethoxysilane (MTEOS) coatings and the rapid assessment of their antibacterial activity using po...

Spectral and directional reshaping of fluorescence from dye molecules embedded in self-assembled hybrid plasmonic-photonic crystals has been examined. The hybrid crystals comprise two-dimensional hexagonal arrays of dye-doped dielectric nanospheres, capped with silver semishells. Comparing the reshaped fluorescence spectra with measured transmission/reflection spectra and numerical calculations...

Nanoparticle filling is a feasible way to increase the mechanical properties of polymer matrices. Abundant research work has been published in the last number of years concerning the enhancement of the mechanical properties of nanoparticle filled polymers, but only a reduced number of studies have been done focusing on the fatigue behaviour. This work analyses the influence of nanoclay reinforc...

Optimally doped silver selenide and silver telluride exhibit linear positive magnetoresistance over decades in magnetic field and on a scale comparable to the colossal magnetoresistance compounds. We use hydrostatic pressure to smoothly alter the band structure of Ag-rich and Ag-deficient samples of semiconducting Ag(2 +/-delta)Te of fixed stoichiometry and disorder. We find that the magnetores...

In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The ...

A compact platform for producing sub-micrometer 3D interconnects and networks for bacterial carriers and electrical signal transmission is briefly presented. The platform is composed of a dispensing system using polyurethane doped with silver nanoparticles, curing system controlling the polymerization process by emitting UV light, and an annealing system which is used to remove the cured resin ...

The effect of nanoclay in combination with other inter fillers in ethylene propylene diene monomer (EPDM) rubber vulcanizate were studied. Curing characteristics were carried out using rubber process analyzer (RPA). Mechanical, thermal and morphology characterization of EPDM nanoclay composites were studied.

A facile one-pot microemulsion method has been developed for the synthesis of spherical silver core-silica shell (Ag@SiO2) nanoparticles with europium chelates doped in the shell through a silane agent. The method is significantly more straightforward than other extant methods. Measurements of the luminescent emissions from the Ag@SiO2 nanoparticles, in comparison with control silica nanopartic...

INTRODUCTION Hearing protection devices are one of the primary noise reduction tools in developing countries. This study is intended to produce and apply acrylonitrile butadiene styrene (ABS)/clay nanocomposites to fabricate a laboratory single cup earmuffs and then compare it with double cup and single cup pure ABS earmuffs in terms of noise attenuation performance and comfort. In addition, th...

introduction of the metallic nanoparticles (nps) in the bulk glass received a large interest due to their versatile applications. the effect of silver nps on optical properties of the eu3+-doped zinc tellurite glasses is presented for the first time. glass samples are prepared by melt-quenching technique. the surface plasmon absorption bands of silver nps are recorded in the visible region. the...
