Fabrication and characterization of Ru-doped LiCuFe2O4 nanoparticles and their capacitive and resistive humidity sensor applications

Polycrystalline ruthenium-doped lithium-copper-ferrite ( Ru-LiCuFe2O4) nanoparticles (NPs) are synthesized using a simple and cost-effective chemical co-precipitation method and annealed at different temperatures for increasing the crystallinity. The transmission and scanning electron microscopy images have confirmed the presence of soft agglomerations and cuboids for the samples annealed at 1100 °C. X-ray photoelectron results along with Raman spectra have collectively demonstrated the presence of Ru in the structure of Ru-LiCuFe2O4 NPs. The dielectric properties of as-synthesized Ru-LiCuFe2O4 NPs are investigated using LCR meter where the smaller NPs demonstrates a higher dielectric constant. Also, the results of magnetic measurements of annealed Ru-LiCuFe2O4 NPs have corroborated a soft magnetic nature due to the pinning sites that endow lower coercivity, remanence and saturation magnetization than that of the pristine one. The variation of permittivity and electrical resistivity with respect to frequency under humidity conditions suggested that this material has a potential to use as capacitive and resistive humidity sensor. The results of this study open the doors for utilization of metal-doped magnetic ferrites for humidity sensing application

E-COMMERCE WEBSITE

The business to consumer aspect of electronic commerce (e-commerce) is the most visible business use of the Word Wide Web. Theprimary goal of an e-commerce site is to sell goods and services online.This project is a web based shopping system for an existing shop. The project objective is to deliver the online shopping application.This project is an attempt to provide the advantages of online shopping to customers of a real shop. It helps buying the products in the shop anywhere through internet by using a web site. Thus the customer will get the service of online shopping and home delivery from this shop. This system can be implemented to Sai Supermarket in the locality.If shops are providing an online portal where their customers can enjoy easy shoppingfrom anywhere, the shops won’t be losing any more customers to the trending online shops such asflipkartoreBay.Sincetheapplicationisavailableinthegivensiteitiseasilyaccessibleand always available

Study on photoelectrochemical solar cells of nanocrystalline Cd0. 7Zn0. 3Se-water soluble conjugated polymer

Cadmium zinc selenide (Cd0.7Zn0.3Se) nanocrystalline thin films were chemically synthesized onto indium tin oxide (ITO)-coated glass substrate at relatively low temperature (<90 °C). The as-deposited films were annealed in air at 200, 300, and 400 °C for 60 min. The structure and surface morphology of the films were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The water-soluble conjugated polymer, poly(2-ethynyl-N-carboxy-propyl-pyridinium bromide) (LM3), with quaternary pyridinium salts was layered by dipping the as-deposited and annealed Cd0.7Zn0.3Se films in the aqueous polymer solution. This hybrid photoanode system was subjected to photoelectrochemical (PEC) study under a light illumination intensity of 80 mW/cm2
