Cobalt ferrite, Copper ferrite and cobalt doped copper nanoparticles have been synthesized characterized using different characterization methods (XRD, FTIR FESEM). The prepared used as promising fillers of the polyvinylidene fluoride (PVDF) polymer. PVDF/(Cu–CoFe2O4, CoFe2O4, CuFe2O4) nanocomposites films via a simple solution casting technique. optical properties piezoelectric response nanoco...

Cylindrical lens array (CLA) and plasmonic nano-grating structures were integrated with a large area interdigitated photoconductive antenna (PCA) for high-efficiency terahertz (THz) emitter applications. The peak-to-peak amplitude of THz radiation pulse from the CLA-integrated PCA was enhanced 5.5 times compared that conventional without CLA. highly localized electric field near nanoscale grati...

A cylindrical metallic plasmonic nano-antenna consisting of a shell supporting a disk, named capped shell, is proposed and studied by frequency domain finite element analysis. This new topology is shown to be weakly dependent on the radius of the structure and is therefore suitable for fabrication by parallel processes such as island lithography which generates a pseudo-random array with a dist...

Photopolymer composites filled with cellulose nanocrystal (CNC) and/or inorganic nanofillers were fabricated by using digital light processing (DLP) 3D printing. To investigate the effects of different CNC lyophilization concentrations and behaviors particles in photopolymer composites, morphological mechanical properties analyzed. loading levels affected composites. Better dispersion was seen ...

Differing from the structure of traditional parallel plate capacitive sensor a semi cylindrical capacitive sensor has been introduced in this present work to measure the soil moisture conveniently. Here, the numerical analysis method to evaluate the capacitance from the semi-cylindrical capacitive sensor is analyzed and discussed. The changes of capacitance with the variation of soil moisture o...

The axial compressive strength of continuous fibres reinforced composite laminates is a key design parameter. Adding nano-fillers to polymer matrices should increase this property but failure modes may change with increasing the nano-filler content. Significant improvement observed It also shown that single experimental tensile test on ±45∘ coupons makes it possible estimate regardless Indeed, ...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...
