• Sommario/riassunto: The present volume "New Trends in Lithium Niobate: From Bulk to Nanocrystals" contains the materials of a Special Issue of the MDPI journal Crystals dedicated to the memory of Prof. Dr. Ortwin F. Schirmer and provides a new synopsis of his research focusing on LiNbO3. It also includes recent developments, exemplifying the continued interest in this outstanding ferroelectric, non-linear optical and holographic crystal as a workhorse for testing and realizing new ideas and applications.This book starts with reviews on intrinsic and extrinsic crystal defects in LiNbO3 of single-crystal, thin-film or nano-powder forms, studied by various optical, magnetic resonance and nuclear methods, clarifying in particular the reasons for the suppression of anion vacancy formation upon thermal reduction, mechano-chemical processing or irradiations of various types. The reviews are followed by research papers on the experimental and theoretical investigation of small polarons, together with recent results on the properties of Li(Nb,Ta)O3 mixed crystals. Among the various contributions dealing with nonlinear optical applications, papers on device development, entangled photon pair generation and thin films on the Lithium Niobate On Insulator (LNOI) platform can also be found.

• Sommario/riassunto: Over the last two decades, the literature on political participation has flourished, reflecting the increasing use of diverse modes of citizen involvement. These include established modes of participation, such as voting, protests, mass demonstrations, and petition signing, but also newer modes specific to the online environment (ICT-related), participation in referendums, public consultations, or engagement in political deliberation. The importance and intensity of these modes is reflected both in the number of people getting involved and in the increasing number of policies that are subject to various modes of participation on a regular basis. There is extensive literature about how these modes of participation function, why people get involved, and the consequences of their participation. However, limited attention is paid to the relationship between political participation and the pursuit of sustainability at a local, regional, or central level. Existing studies indicate that citizen engagement can be a cost-effective method to characterize changes of local environments; however, not much is known beyond this process. This Special Issue aims to address this void in the literature and brings together contributions that analyze how participation can be associated with sustainability and local development in various settings. It explores the relationship between political participation and the management of their local environment. This Special Issue enhances the existing knowledge and understanding ; about how modes of participation can be reflected in stronger sustainability. The Special Issue provides the space for an academic debate that addresses issues such as climate change, resource allocation, or the pursuit of sustainability programs and policies. The contributions include a mix of single-case studies and comparative analyses across European countries.
