Research ArticleOpen accessIn the keywordsPreparation of LiCoMnO4 Assisted by Hydrothermal Approach and its Electrochemical PerformanceMeilin You, Xingkang Huang, Min Lin et al.LiCoMnO4 materials have been synthesized via a hydrothermal approach followed by a post-annealing process. Pure phase of LiCoMnO4 is unable to form under hydrothermal conditions; however, high quality of pure LiCoMnO4 was achieved after annealing the hydrothermal products. The concentration of LiOH and the post-annealing temperature are the crucial factors to form LiCoMnO4. Without post-annealing process, the highest contents of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 23 May 2016 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Method for Transmitting Spacecrafts in Space with Velocity of at Least 0.01 of the Light Speed Using Materials with Very High Kinetic Energy in High Electric FieldsMario Nady AiadMany space new missions are on calendar this decade for Moon, Mars and other planets. Some of these missions are depending on simple reliable chemical thrusters and others on the nonchemical advanced propulsion techniques. In most of nonchemical techniques a nuclear source of energy is necessary as in nuclear electric rockets where the maximum velocity produced is around 20 km/s. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 22 Dec 2023 · 5,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Bioelectricity Using Single Chamber Microbial Fuel CellAhmad Nawaz, Ram Sharan SinghThe present study addressed the application of sandwich-type air cathode microbial fuel cell (ACMFC) for the production of bioelectricity. Activated carbon was pasted on aluminum mesh for the manufacture of anode and cathode. This electrode design eliminated the requirement for carbon cloth or a metal catalyst, resulting in a cathode with excellent activity for oxygen reduction. The findings demonstrated that … …American Journal of Environmental Sciences, Vol. 19, Issue 2 · 4 Sep 2023 · 5,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of Bipolar Plate for 500w Pem Fuel Cell StackA. Kalaiyarasan, C. Srinivasan, S. SundaramThe PEM Fuel Cell (PEMFC) performance depends on the operating parameters like temperature, pressure, stoichiometric ratio of reactants, relative humidity, back pressure on anode and cathode flow channels, and the design parameters like rib width to channel width (L:C), channel depth, shape of the flow channel and number of pass on the flow channel. The voltage and power produced by … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 13 Jan 2018 · 7,895 accessesView PDFCite
