Drastic microstructural modification of Bi2Ca2Co2Oyceramics by Na doping and laser texturing
(Sociedad Espanola de Ceramica y Vidrio, 2022)
Bi2Ca2-xNaxCo2Oy materials with x = 0 < x < 0.125, have been prepared either by sintering through the classical ceramic method, or textured using the laser floating zone technique. XRD results have shown that Bi2Ca2Co2Oy ...
Thermoluminescence of hydroxyapatite from eggshell powders doped with Dy synthesized by the sonication chemical method: Effects of doping concentration and heating rate
(Elsevier, 2022)
Hydroxyapatite (HAP) was selected as the host material and synthesized using a sonication chemical method. The effect of Dy3+ ion doping concentrations (0.25, 0.5, 1, 2, 3, 4, 5, 7, and 10 wt%) on the structure and ...
Simulation and Modelling of A Solar-Aided Underground Energy Storage System
(Serbian Society of Heat Transfer Engineers, 2023)
The significance of energy storage methods and related R and D studies are increasing due to the depletion of fossil fuels, rising energy prices, and growing environmental concerns. Storage of energy means elimination of ...
