Modeling and Simulation of Chemical and Mass Transfer Processes in Industrial Column Apparatuses

Theoretical study of the techniques for modelling and simulating industrial processes is offered in this chapter. The need for knowledge about the interphase boundaries and velocity distributions in the phases in the column apparatuses and the interaction between the simple (elementary) processes in the complex process, i.e., knowledge about the process mechanism, lead to two…

Polydiorganosiloxane-polyphenylsilsesquioxane Block Copolymers Bearing Various Si-substituents: Synthesis, Properties

Polydiorganolsiloxane oligomers containing various Si-substituents and polyphenylsilsesquioxane oligomers have been used to create block copolymers. In contrast to the linear polydiorganolsiloxane counterparts, the products are soluble, amorphous, and exhibit excellent thermal characteristics. These silicone block copolymers’ structures, molecular weights, and thermal stability characteristics were examined. The overall goal of research is to produce high molecular…

Modification to a Formulation for Optimal Performance: A Review

In a chemical reaction, reactant material transforms into product material, which has distinct physical and chemical properties from reactant material. Detectable changes are present in every chemical reaction, including colour changes, bubbling, heat evolution, heat absorption, light emission, and precipitate formation. Precipitation reactions, acid base reactions, and oxidation reduction reactions are the three primary types…

TEM Cross-Section Sample (XTEM) Preparation of nc-Si/a-SiO2 Multi-Layer Thin Film Using cryo Ar+ Ion Slicing for Microstructural Analyses

Third generation solar cell researchers are paying close attention to thin films of multi-layered nanocrystalline silicon (nc-Si). The multi-layered amorphous hydrogenated a-Si:H/a-SiO2 films created by plasma enhanced chemical vapour deposition (PECVD) are reported in this chapter. The nc-Si/a-SiO2 multilayer was then produced by annealing the thin film that had just been formed at 1100°C. For…

Sulphuric Acid Bake-Leach Process for the Treatment of Mixed Copper-Cobalt Oxide Ores: An Experimental Study

For the treatment of mixed copper-cobalt oxide minerals, a sulphuric acid bake-leach process was investigated as an alternative to reductive leaching. On the dissolution of copper and cobalt, the effects of acid dose, baking temperature, baking duration, and leaching time were examined. The combined copper-cobalt oxide ore was treated with sulphuric acid before being baked…

Evaluating Wear Performance of Silicon Nitride-Hexagonal Boron Nitride Composite Using Taguchi Method

The goal of bio-tribology research is to determine which biomaterials will wear the least. Recently, silicon nitride (Si3N4) has been suggested as a substitute material for hip and knee joint replacement. Hexagonal boron nitride can be used to improve Si3N4’s wear characteristics (hBN). Methods/Analysis: In order to reduce wear loss, this study evaluates the sliding…

Determining the Influence of Chromium Concentration on the Erosive Wear of Ni-Cr-B-Si Coatings Applied by Supersonic Flame Jet (HVOF)

The goal of the current research is to examine how the chromium content of powder composites affects the erosion wear of Ni-Cr-B-Si coatings applied by supersonic flame jet on substrates with and without thermal treatment. Coatings were created from each powder composite without any prior heat treatment of the sub-strate and with some preliminary thermal…
