The textile industry segment has been continuously expanding and it is reported that the global market was US$1000 billion in 2020. Aside from the fact that textile industry could be profitable and offers several advantages for human life, this industry produces wastewater containing many harmful substances in the form of organic and inorganic moieties. Textile wastewater can lead to serious environmental problems if discharged without treatment. In this first volume of the application of biological mechanisms, processes and units are reviewed in terms of dye degradation and removal. The role of biodegradation, bioaccumulation and biosorption in bio-decolorization are discussed. The book starts with highlighting the fundamentals of aerobic and anaerobic mechanisms having different configurations. The moving bed bioreactor (MBBR), up-flow anaerobic sludge blanket reactors, sequential aerobic/anaerobic batch reactors, membrane bioreactor, etc are also covered in this edition.

The effective removal of dyes from aqueous waste is an important issue for many industrialized countries. The traditional treatment methods used to remove dyes from wastewater have certain disadvantages such as incomplete dye removal, high reagent and energy requirements, and the generation of toxic sludge or other waste products that require disposal. The search for alternative and innovative treatment techniques has focused attention on the use of biological materials for dye removal and recovery technologies. This brief summarizes the latest developments in this important field.

The rapid growth of global energy consumption and simultaneous waste discharge requires more sustainable energy production and waste disposal/recovery technology. In this respect, microbial fuel cell and bioelectrochemical systems have been highlighted to provide a platform for waste-to-energy and cost-efficient treatment. Microbial fuel cell technology has also contributed to both academia and industry through the development of breakthrough sustainable technologies, enabling cross- and multi-disciplinary approaches in microbiology, biotechnology, electrochemistry, and bioprocess engineering. To further spread these technologies and to help the implementation of microbial fuel cells, this Special Issue, entitled "Microbial Fuel Cells 2018", was proposed for the international journal Energies. This Special Issue mainly covers original research and studies related to the above-mentioned topic, including, but not limited to, bioelectricity generation, microbial electrochemistry, useful resource recovery, system and process design, and the implementation of microbial fuel cells.

Mechanical alloying is a technique of producing alloys and compounds that permits the development of metastable materials (with amorphous or nanocrystalline microstructure) or the fabrication of solid solutions with extended solubility. The elements or compounds to be mixed (usually as powders) are introduced in jars usually under a controlled atmosphere. Regarding the scope of this book, advanced materials have been developed by mechanical alloying: Fe–X–B–Cu (X = Nb, NiZr) nanocrystalline alloys, mixtures of the binary Fe–Mn and Fe–Cr alloys with chromium and manganese nitrides, Mn–Al–Co and Mn–Fe alloys, non-equiatomic refractory high-entropy alloys, nanocrystalline Fe–Cr steels, nanaocrystalline Mn–Co–Fe–Ge–Si alloys, Al–Y2O3 nanocomposite, and hydride-forming alloys. Likewise, production conditions and ulterior treatments can provide readers interesting ideas about the procedure to produce alloys with specific microstructure and functional behavior (mechanical, magnetic, corrosion resistance, hydrogen storage, magnetocaloric effect, wastewater treatment, and so on). As an example, to obtain the improvement in the functional properties of the alloys and compounds, sometimes controlled annealing is needed (annealing provokes the relaxation of the mechanical-induced strain). Furthermore, the powders can be consolidated (press, spark plasma sintering,and microwave sintering) to obtain bulk materials.
