Eco-Friendly Approaches to Chemical Synthesis | Chapter 2 | Recent Developments in Science and Technology for Sustainable Future

 Green Chemistry entails revolutionary advancements in compound exploration and production, aimed at reducing or eliminating the use and generation of hazardous substances in the manufacturing, design, and applications of chemicals. The rapid evolution of Green Chemistry is propelled by the realization that environment friendly products and methodologies are not only ecologically responsible but also economically viable in the long run. In the development of new components, yields, or processes, researchers and engineers adhere to a framework that diverges from conventional manufacturing practices, prioritizing considerations of environmental impact, economic feasibility, and societal well-being. This adherence is guided by the twelve principles of Green Chemistry, which comprehensively address the interplay of environmental, economic, and public factors. This chapter provides a concise overview of Green Chemistry in synthetic methods, delving into various techniques such as mechanochemistry (grinding), photochemical processes, ultrasound or sonochemical methods, microwave irradiation, and solvent-free conventional thermal heating. Each of these methods exemplifies the commitment to sustainable and environmentally benign practices in chemical synthesis.

Particle Breakage Mechanisms in a Horizontal Stirred Mill: A Morphological Study | Chapter 02 | Technological Innovation in Engineering Research Vol. 1

 The morphological properties of particles pulverised in a stirred mill were studied using automated and manual detection methods in this work. Particle breaking processes such as fracture or abrasion determine the morphological surface qualities of product particles. To reduce comminution energy consumption, it is critical to promote breaking mechanisms that accomplish mineral release with the least amount of energy. Intergranular particles should have rough surfaces, whereas transgranular particles should have softer surfaces. High-speed swirled mills, according to the literature and common belief, shatter particles by attrition. In this investigation, fracture was discovered to be an important breaking mechanism alongside attrition. The mill agitator acts as an input stress level. The breaking mechanism is affected by mill agitator speed as well as the kind of mineral. At greater agitator speeds, galena fractures along grain boundaries, whereas quartz abrades throughout the grain.
