The improvement of SnS 2 photocatalyst can be conducted through structural modification, morphological manipulation, and heterojunction formation.
Co-doped ZnO nanoparticles are synthesized by co-precipitation method. The incorporation of Co ions into wur- zite structure with increasing concentrations was followed X-ray diffraction. Sample structures were further studied infrared spectra, from which a broad and strong absorption band in the range 400 - 700 cm-1 -OH stretching vibrational mode approximately 3400 observed. Ultraviolet-visible measurements showed red shift edge four peaks at 468, 515, 577 629 nm its reflectance spectra...
Ce-doped ZnO nanoparticles with various doping concentrations of cerium ion were prepared by the co-precipitation method. All characterized electron spin resonance (ESR), energy-dispersive X-ray spectroscopy (EDX), diffraction (XRD) and UV-Vis diffuse reflectance spectroscopy. show pattern that matched in its wurzite structure average grain size was range 13 - 16 nm. measurements indicated a red shift photophysical response after exhibited reflection spectra visible region between 300 800 In...
A series of copper oxide supported on Fe 3 O 4 /ZnO with molar ratio :ZnO:CuO varies from 1:1:1 to 1:1:5 were prepared by sol-gel method. X-ray diffraction, field emission scanning electron microscope, energy-dispersive spectroscopy, UV-visible diffuse reflectance spectroscopy and vibrating sample magnetometer used characterize the as /ZnO/CuO hybrid nanoparticles. The results show that nanoparticles consist cubic spinel , hexagonal wurtzite ZnO monoclinic CuO. All samples ferromagnetic...
Electronic cane: It is an electronic cane designed in the shape of a long white cane, but it provides blind with ultrasonic frequencies that he can feel under his hand and through audible alarm when hits certain obstacle its path{1}. also detect obstacles all directions at distance five meters. The ends this are made lead. International Federation Blind, which one organizations affiliated United Nations, has declared October 15 each year as Day White Cane for due to utmost importance blind,...
The main objective of this research is to examine the load-deflection behavior White Concrete-Hollow Core Slab (WC-HCS) panels, which were made using white cement, crushed Limestone (LS) as sand, and coarse LS aggregate. panels subjected symmetrical two-point static loads results compared with Normal (NC-HCS) utilizing gravel. flexural response steel-reinforced Hollow (HCS) was also evaluated. experimental study involved casting 12 HCS specimens. Each slab had dimensions 1000 mm length 450...
