In the context of the disruption caused by the Covid-19 pandemic, the Horn of Africa remains one of the most dynamic and intriguing regions on the African continent. The political processes currently under way – including the recent conflict in Ethiopia’s Tigray region – have deep implications that reflect on the domestic equilibria within the area’s core states – Ethiopia itself, but…
This book investigates the ways in which soft power is used by African countries to help drive global influence. Selecting four of the countries most associated with soft power across the continent, this book delves into the currencies of soft power across the region: from South Africa’s progressive constitution and expanding multinational corporations, to Nigeria’s Nollywood film industry …
Abstract The book on Advanced Chemical Kinetics gives insight into different aspects of chemical reactions both at the bulk and nanoscale level and covers topics from basic to high class. This book has been divided into three sections: (i) "Kinetics Modeling and Mechanism," (ii) "Kinetics of Nanomaterials," and (iii) "Kinetics Techniques." The first section consists of six chapters with a vari…
Abstract This reprint is concerned with the microstructural characterization and the defect analysis of metallic additively manufactured (AM) materials and parts. Special attention is paid to the determination of residual stress in such parts and to online monitoring techniques devised to predict the appearance of defects. Finally, several non-destructive testing techniques are employed to ass…
Abstract Ceramic oxides typically have a combination of properties that make them attractive for many applications compared with other materials. This book attempts to compile, unify, and present a recent development for the production techniques, such as electrochemical, foaming, and microwave sintering, of rare earth ceramic oxide materials. This book presents leading-edge research in this f…
Abstract This book examines exciting advancements in the field of ceramics, including nanotechnology, clean energy, and tribology as well as fundamental concepts like defects and structure. It is a comprehensive discussion on how today’s ceramics are processed and used in many of today’s critical technologies. It discusses current techniques for synthesizing durable and cost-effective cera…
Abstract Todays chemical industry processes worldwide largely depend on catalytic reactions and the desirable future evolution of this industry toward more selective products, more environmentally friendly products, more energy-efficient processes, a smaller use of hazardous reagents, and a better use of raw materials also largely involves the development of better catalysts and, specifically,…
Abstract This Special Issue is related to studies of the hydrogen production from formic acid decomposition. It is based on five research papers and two reviews. The reviews discuss the liquid phase formic acid decomposition over bimetallic (PdAg), molecular (Ru, Ir, Fe, Co), and heterogenized molecular catalysts. The gas-phase reaction is studied over highly dispersed Pd, Pt, Au, Cu, and Ni s…
Abstract Major casting processing advancements have been made in experimental and simulation areas. Newly developed advanced casting technologies allow foundry researchers to explore detailed phenomena associated with new casting process parameters helping to produce defect-free castings with good quality. Moreover, increased computational power allows foundry technologists to simulate advance…
Abstract This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential …
