In 2011, the European Union elaborated a list of critical raw materials (CRMs), taking the economic and strategic importance for the European economy and the supply risk. Although focused mainly on the energy sector, the USA, Canada, and other countries took recently similar steps. Despite the great inertia characterising the mineral raw materials sector, some steps towards the Industry 4.0 paradigm can be envisaged. Significant challenges to the mining sector are the appropriate process design using the best available technologies; the increase in energy efficiency; the responsible use of water and handling of mining wastes; the social acceptance of the activity; and the digitalisation challenge. This book aims to propose strategies that can help face those challenges, especially in increasing energy efficiency in comminution operations.History of engineering and technologybicsscMining technology and engineeringbicsscTechnology: general issuesbicsscball millball millsbond work indexBond work indexcomminutioncritical metalscritical raw materialselectrofragmentationenergy efficiencygrindabilitygrinding kineticsgrinding mediakinetic grindingMarx generatormetallurgical cokemodelingn/aparticle size distributionPenouta MinesimulationSn-Ta-Nbspecific grinding ratetungsten orework indexHistory of engineering and technologyMining technology and engineeringTechnology: general issuesMenéndez-Aguado Juan Medt1326295Menéndez-Aguado Juan MothBOOK9910566466803321Grinding and Concentration Technology of Critical Metals3037276UNINA04121nam 22006495 450 991030053480332120200701115423.03-319-69599-110.1007/978-3-319-69599-0(CKB)4100000000882505(DE-He213)978-3-319-69599-0(MiAaPQ)EBC5112686(PPN)220126305(EXLCZ)99410000000088250520171024d2018 u| 0engurnn|008mamaatxtrdacontentcrdamediacrrdacarrierThe (Non-)Local Density of States of Electronic Excitations in Organic Semiconductors /by Carl.

By tracing the link between their morphological structure and electronic properties across multiple scales, it represents an important advance in this direction.  Organic semiconductors are materials at the interface between hard and soft matter: they combine structural variability, processibility and mechanical flexibility with the ability to efficiently transport charge and energy. This unique set of properties makes them a promising class of materials for electronic devices, including organic solar cells and light-emitting diodes. Understanding their function at the microscopic scale – the goal of this work – is a prerequisite for the rational design and optimization of the underlying materials. Based on new multiscale simulation protocols, the book studies the complex interplay between molecular architecture, supramolecular organization and electronic structure in order to reveal why some materials perform well – and why others do not. In particular, by examining the long-range effects that interrelate microscopic states and mesoscopic structure in these materials, the book provides qualitative and quantitative insights into e.g. the charge-generation process, which also serve as a basis for new optimization strategies.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053SemiconductorsOptical materialsElectronicsMaterialsPolymersPhysicsSemiconductorshttps://scigraph.springernature.com/ontologies/product-market-codes/P25150Optical and Electronic Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z12000Polymer Scienceshttps://scigraph.springernature.com/ontologies/product-market-codes/C22008Applied and Technical Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31000Semiconductors.Optical materials.ElectronicsMaterials.Polymers.Physics.Semiconductors.Optical and Electronic Materials.Polymer Sciences.Applied and Technical Physics.530.416Poelking Carl.
