Purpose: The application of arc discharge to synthesising encapsulated (Fe-Cu-Al)@C structures is studied. The cost-effectiveness of the proposed technique may be beneficial for developing a new method for large-scale production of metal micro- and nanoparticles protected from oxidation by a carbon shell. Design/methodology/approach: A copper sample was immersed into a mixture of graphite, iron, and...
Purpose: Analysis of different path planning strategies and the effects of changing printhead direction in the geometrical conformity and the process precision around 90° corner in order to enable a simple and cost-effective way of facilitating the determination of an optimal printing mode for fast and accurate print corners in 3D concrete printing. Design/methodology/approach: The material flow is...
Purpose: The work’s primary goal is to assess the influence of the cotton fibres addition and their proportion on the strength properties and thermal conductivity of foamed geopolymer composites based on fly ash. Design/methodology/approach: Fly ash from a thermal power plant was used as the foundation material to create the geopolymer composites in this study. Volcanic silica was used as an additional...
Purpose: Drill less dentistry is painless, riskless, soundless and heatless and is very suitable for dental-related concerns where children are the most affected fraternity. Removing enamel from the teeth at the affected region by conventional drilling mechanism is challenging. The processed region is filled using amalgam or other sources for the occupation. The proceedings are a painful experience...
