Nature, with its unassuming yet prodigious character, unfolds its assembly and adaptability guided by the principles of thermodynamics and supramolecular chemistry. Every entity in nature, regardless of its form, adheres to these fundamental principles. From individual metabolites to ordinary molecules, each possesses inherent potential for nanomaterial synthesis. This book meticulously compiles diverse green approaches that highlight nature's synthetic prowess and its lavish abundance in nanomaterial synthesis, showcasing potential applications. It unveils the lucrative pathways nature provides for cutting-edge advancements in synthetic methodologies and material applications.
This is a collection of papers presented in the symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Paper topics include the extraction and processing of elements like antimony, arsenic, gold, indium, palladium, platinum, rare earth metals including yttrium and neodymium, titanium, tungsten, and vanadium. The rare processing techniques covered include direct extraction process for rare earth element recovery; biosorption of precious metals; fluorination behavior of uranium and zirconium mixture of fuel debris treatment; and recovery of valuable components of commodity metals such as zinc, nickel, and metals from slag.
This book introduces the engineering application of the discrete element method (DEM), especially the simulation analysis of the typical equipment (scraper conveyor, coal silos, subsoiler) in the coal and agricultural machinery. In this book, the DEM is applied to build rigid and loose coupling model, and the kinematic effect of the bulk materials, the mechanical effect of the interaction between the bulk materials, and the mechanical equipment in the operation process of the relevant equipment are studied. On this basis, the optimization design strategy of the relevant structure is proposed. This book effectively promotes the application of DEM in engineering, analyzes the operation state, failure mechanism, and operation effect of related equipment in operation, and provides theoretical basis for the optimal design of equipment. The book is intended for undergraduate and graduate students who are interested in mechanical engineering, researchers investigating coal and agricultural machinery, and engineers working on designing related equipments.
The 10-volume set LNCS 14254-14263 constitutes the proceedings of the 32nd International Conference on Artificial Neural Networks and Machine Learning, ICANN 2023, which took place in Heraklion, Crete, Greece, during September 26–29, 2023. The 426 full papers, 9 short papers and 9 abstract papers included in these proceedings were carefully reviewed and selected from 947 submissions. ICANN is a dual-track conference, featuring tracks in brain inspired computing on the one hand, and machine learning on the other, with strong cross-disciplinary interactions and applications.
This book provides an introduction to optical multidimensional coherent spectroscopy, a relatively new method of studying materials based on using ultrashort light pulses to perform spectroscopy. The technique has been developed and perfected over the last 25 years, resulting in multiple experimental approaches and applications to a broad array of systems ranging from atoms and molecules to solids and biological systems. Indeed, while this method is most often used by physical chemists, it is also relevant to materials of interest to physicists, which is the primary focus of this book. As well as an introduction to the method, the book also provides tutorials on the interpretation of the rather complex spectra that is broadly applicable across all subfields, and finishes with a survey of several emerging material systems and a discussion of future directions.
Advances in synthesis of metallic, oxidic and composite powders were presented via the following methods: ultrasound-assisted leaching¸ ultrasonic spray pyrolysis, hydrogenation, dehydrogenation, ball milling, molten salt electrolysis, galvanostatic electrolysis, hydrogen reduction, thermochemical decomposition, inductively coupled thermal plasma, precipitation and high pressure carbonation in an autoclave. This Special Issue contains 17 papers from Europe, Asia, Australia, South Africa and the Balkans. The synthesis was focused on metals: Co, Cu; Re; oxides: ZnO, MgO, SiO2; V2O5; sulfides: MoS2, core shell material: Cu-Al2O3, Pt/TiO2; compounds: Ca0.75Ce0.25ZrTi2O7, Mo5Si3, Ti6Al4V. The environmentally friendly strategies were presented at the carbonation of olivine, treatment of acid mine drainage water and production of vanadium oxide.
With the rapid development of machinery, materials science and energy engineering technology in China, new theories and application results constantly appear. Higher and newer requirements in these fields are sought by business enterprises and members of the engineering profession.This conference was held to further promote the exchange and cooperation among local researchers, to upgrade the academic standards and international influence on the study of these fields in China, and to play a positive role in bridging the gap with the international research community.This volume consists of 106 peer-reviewed articles by local and foreign eminent scholars which cover the frontiers and hot topics in machinery and process equipment, materials science, energy engineering and mechatronics.
