Blockchain and cryptocurrencies have recently captured the interest of academics and those in industry. Cryptocurrencies are essentially digital currencies that use blockchain technology and cryptography to facilitate secure and anonymous transactions. The cryptocurrency market is currently worth over {dollar}500 billion. Many institutions and countries are starting to understand and implement …
Block copolymers with crystallizable blocks have moved into the focus of current research, owing to their unique self-assembly behaviour and properties. New synthetic concepts give, for example, even access to tetrablock copolymers with four crystalline blocks, bio-based thermoplastic elastomers (e.g., based on ABA triblock copolymers with poly(L-lactide) (PLLA) hard segments), and allow new, e…
The world in which we currently live is characterised by a multiplicity of challenges that we must face with urgency if we want to avoid future catastrophes. Those challenges, because of the globalisation of systems, have also become global challenges, and need global responses. One of the most important of those challenges faced by the current global community remains the environmental crisis,…
Flight during times of persecution has a long and fraught history in early Christianity. In the third century, bishops who fled were cowards or, worse yet, heretics. On the face of it, it meant denial of Christ and thus betrayal of the faith and its community. But, by the fourth century, the terms of persecution changed as Christianity became the favored cult of the Roman Empire. Prominent Chri…
This book covers the latest development of bioprocess technology including theoretical, numerical, and experimental approaches in biotechnology as well as green technology that bridge conventional practices and Industry 4.0. Bioprocessing is one of the key factors in several emerging industries of biofuels, used in the production of biogas, bioethanol, and biodiesel; industrial enzymes; waste m…
This Special Issue, "Biotechnology Applications of Microalgae", is focused on the latest novel advances related to the production of different bioactive compounds from microalgae and their biotechnological use.
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 researcher…
Many soils worldwide are contaminated with potentially toxic elements (PTEs). These elements can be taken up by plant roots and accumulate in plants’ organs, thus becoming a danger for the health of humans and animals. Therefore, it is still essential and urgent to understand the behavior of such contaminants in soil and find sustainable approaches to reduce the risk posed by their presence i…
In this book a novel optical switch is designed, developed, and tested. The switch integrates optical switching, transparent traffic aggregation/grooming, and optical regener-ation. Innovative switch subsystems are developed that enable these functionalities, including all-optical OTDM-to-WDM converters. High capacity ring interconnection between metro-core rings, carrying 130 Gbit/s OTDM traff…
