Possible Nature of Electrical Conductivity of the Corund-Graphene Composite: A Recent Study

The study looks at how sintering modes affect the electrical conductivity of corundum-graphene composites. The characteristics of the electrically conductive structure and its production circumstances are supported by evidence. The goal of this study is to learn more about the nature of conducting structure creation after receiving a corundum-graphene composite and to support the necessity…

Experimental Investigation on the Characterization of HA/Alumina and HA/mgo Nanocomposites for Orthopedic Applications

 For the first time, HA/Alumina and HA/MgO nanocomposites were effectively produced at 250°C utilising the hydrothermal technique. In HA/Alumina and HA/MgO nanocomposites, the mechanisms of composite production, crystallite size, crystallinity, and shape were investigated. An intermolecular interaction between HA/Alumina and HA/MgO was discovered using XRD and FTIR techniques. The nature of the formation of HA/Alumina…

Bauxite Mining Industry in Guinea and the Valorization Prospects of the Resulting Residue for Engineering Purposes

Because of the importance and diversity of its natural riches, Guinea is recognised as a geological disaster. Experts, regardless of the grading system, utilise superlatives to highlight the country’s tremendous potential. Guinea has 33 percent of the world’s known bauxite reserves, according to several geological surveys. The way a deposit’s content is defined is inconsistent,…

Thermo Catalytic Decomposition of Methane over Cu – Al2O3 and 5 – 20wt% Ni – Cu – Al2O3 Catalysts to Produce Hydrogen and Carbon Nanofibers: Experimental Investigation

Hydrogen is an environmentally beneficial fuel with the potential to reduce the use of fossil fuels greatly; yet, it faces numerous important difficulties before it can be widely adopted. TCD (thermo catalytic decomposition of methane) is one of the most useful strategies for fulfilling future demand and, as a result, an appealing approach for COx-free…

Study on Composite Solid Electrolyte Systems: Theory and Materials

Electrical qualities of materials have supported our convenient everyday existence since the discovery of electricity, and “electrical conduction” has been one of the most important properties of materials. In materials, there are two types of electrical conduction: electronic conduction, which uses electrons or holes as charge carriers, and ionic conduction, which uses ions as charge…

Influence of Technology of Nanopowder Production on the Microstructure of the Sintered by Spark-Plasma Material

A comparison of the Spark-Plasma Sintering (SPS) results of two types of aluminium oxide nanopowders generated through conductor explosion and plasma synthesis. The qualities of the resulting compacts are notably different in mechanical properties and microstructure when the parameters of both powders are similar (spherical form of the particles, size, phase composition), as well as…
