lini0.5co0.5vo4 has been successfully synthesized by tartate precursor combustion method using li2co3, co(no3)2.6h2o, ni(no3)2.6h2o and nh4vo3 as a starting materials in deionized water with the subsequent calcination at 450-600 oc for 12 h. the combustion and decomposition of tartate precursor were studied by tga and compared with tartaric acid. it found weight loss at 50-450 oc. the product s...
in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...
Rechargeable batteries have largely replaced primary cells as they save resource and reduce pollution. Recent increases in demand for oil, with the associated environment sustainable issues are continuing to exert pressure on an already stretched and strained world energy infrastructure. Clean and efficient energy production from renewable sources is wanted in our energy and environment-conscio...
In this paper, a 1.85V reduction in driving voltage of an OLED is presented by using an alkali-metal doped electron transport layer (ETL) and a silver (Ag) cathode. Such an ETL is composed of 2,9-dimethyl-4,7-diphenyl 1,10phenanthroline (BCP) doped with Cseium (Cs) to increase the conductivity of the organic material and achieve ohmic contact at the ETL/cathode interface regardless the work fun...
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 goal of this study was to develop a rechargeable aluminum–air battery with high capacity and longterm durability in charge–discharge electrochemical reactions. We used aluminum terephthalate as a metal–organic framework (MOF) material for the air cathode and 1-ethyl-3-methylimidazolium chloride as an ionic liquid electrolyte. When we used aluminum terephthalate as an air cathode material, t...
Conditioning of the insert inside a hollow cathode is believed to be important to ensure reliable discharge initiation and subsequent cathode operation. The desorption of contaminates is reported from hollow cathodes as a function of heater power to quantify cathode conditioning characteristics and identify factors that might prevent the fast initiation of a discharge. In addition to conditioni...
In this study, different cathode materials were evaluated for electrochemical degradation of aqueous phase trichloroethylene (TCE). A cathode followed by an anode electrode sequence was used to support reduction of TCE at the cathode via hydrodechlorination (HDC). The performance of iron (Fe), copper (Cu), nickel (Ni), aluminum (Al) and carbon (C) foam cathodes was evaluated. We tested commerci...
A general X-ray tube has two electrodes, the cathode and the anode, with a high voltage applied between them. Electrons are generated at the cathode. After the electrons are emitted from the cathode they are accelerated by the high voltage toward the anode (positive) electrode. The high speed electrons hitting the anode material then generate invisible radiation i.e. X-rays. The energy spectrum...
