Abstract This research addresses the pressing demand to enhance energy density and power in storage devices, including batteries, fuel cells, supercapacitors. Here, NiMn 2 O 4 is synthesized using urea combustion method. Characterization techniques, powder x-ray diffraction, field emission scanning electron microscopy, BET analysis, are employed investigate its properties. The diffraction peaks showed that NMO had a face-centered tetragonal structure, Scherrer equation was used figure out...
Abstract Efficient energy storage strategies have become a major priority in the last few years. Transition metal sulphides are popularly known as attractive electrode materials or supercapacitors due to their high theoretical capacitance, excellent electrical conductivity, and favourable redox properties. Through compositional structural engineering, some transition like Mn, V, Co, Fe, Cu, Ni, Mo, Zn, W, Sn shown substantial improvements electrochemical performance. Composite engineering...
In this study, novel adsorbents were developed by functionalizing multiwalled carbon nanotubes with frankincense (Fr-fMWCNT) and adding iron oxide (Fe
Excitation functions of the reactions 89Y(p,n) 89Zr, 89Y(p,2n) 88Zr and 89Y(p,pn) 88Y were measured from their respective thresholds up to 17.7 MeV, with particular emphasis on data for production medically important radionuclide 89Zr. The conventional stacked-foil technique was used, samples irradiation prepared by sedimentation process. excitation obtained compared those calculated theoretically using ALICE-IPPE code. also available literature values. From experimental theoretical yields...
Lithium-ion batteries (LIBs) are highly promising energy storage devices because they provide high power output and an extended cycling lifespan, resulting in a unified efficient system. However, the current lithium-ion have limitations providing density due to slow spread of Li + ions low electrical conductivity anode cathode materials. This trade-off results situation where is concentrated rather than energy. Furthermore, significant disparities capacity kinetics between lead subpar rate...
Abstract The excitation functions of proton induced nuclear reactions on nat Te were measured using the stacked-foil technique up to 14.5 MeV. Samples thin uniform layers Ti-backing prepared by electro-deposition. Nuclear reaction cross sections for formation 120g,121,123,124,125,126,128,130(m+g) I determined and their theoretical thick target yields calculated. obtained data compared with previously published experimental results values theoretically ALICE-IPPE computer code.
Poly(hydroxamic acid) resin (PHA) was prepared by modification of polyacrylamide (PAAm) through -irradiation technique and used for the first time in separation Zr(IV) from Y(III) Sr(II) as a simulation mode purification 89 Zr its parents (Y or Sr). The adsorption behaviors zirconium, yttrium, strontium on PHA different media, namely, hydrochloric acid, acetate buffer, citrate buffer were studied function pH. In addition, cation-exchange column chromatography experiments using PHA, three...
Abstract The activation cross sections of proton induced reactions on nat Sb target leading to the formation radioisotopes 121m,g,123m Te were measured. experimental excitation functions compared with theoretical model calculations using codes EMPIRE-3.1 and TALYS-1.4. integral yields three radionuclides calculated possibility their production is discussed.
