development of an eco-friendly, low cost and high energy density limnpo4 cathode material has attracted much attention due to its high operating voltage vs. li falling within the electrochemical stability window of conventional electrolyte solutions and offers more safety features due to the presence of a strong p-o covalent bond.synthesis of battery materials integrates the battery technology ...
The hexagonal zinc oxide coated nickel (Ni/ZnO) nanostructure photocatalyst has successfully been prepared by the reduction of nickel chloride hexahydrate using hydrazine hydrate through the solvothermal process at 140 °C followed by surface modification of the product by the reflux method at 110 °C for 1 h. The X-ray diffraction (XRD) pattern showed that the 'as prepared' sample consists of fa...
new selective coating materials are developed and used in advanced solar collector and absorber designs with improved efficiency. cobalt and copper sulfides nanoparticles are high interest for absorbers of solar thermal collectors due to their optical properties and high absorptance in the solar wavelength range (> 96%). in the present work, cobalt and copper sulfides nanoparticles were synthes...
silver nanowires were synthesized by solvothermal method through reducing silver nitrate (agno3) with ethylene glycol (eg) in the presence of polyvinylpyrrolidone (pvp). in order to prevent the agglomeration of ag+ in the initial ag seeds formation, sodium chloride (nacl) was added into the solution to form agcl colloids. by dissolving agcl in the late stages, ag+ ions were released into the so...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
Incorporation of vertically aligned nanorod/nanowire arrays of metal oxide (oxide-NAs) with a polymer can produce efficient hybrid solar cells with an ideal bulk-heterojunction architecture. However, polymer/oxide-NAs solar cells still suffer from a rather low (normally, < 0.4 V) open-circuit voltage (Voc). Here we demonstrate, for the first time, a novel strategy to improve the Voc in polymer/...
Copper nanoparticles were synthesized on multiwall carbon nanotubes, (Cu)/(MWCNTs), based on solvothermal method. The used reagents include MWCNTs, cupric nitrate trihydrate (Cu (NO3)2.3H2O), diethylene glycol (DEG), diethanol amine. Characterization of Cu/MWCNTS nanoparticles was performed by techniques of Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction sp...
