π-Conjugated molecules with an even number of π-electrons usually have a closed-shell ground state. However, recent studies have demonstrated that a certain type of molecules could show open-shell singlet ground state and display diradical-like (diradicaloid) behavior. Their electronic structure can be understood in terms of the “diradical character” and “aromaticity” concepts. They display very different electronic properties from traditional closed-shell π-conjugated molecules and could be used as next-generation molecular materials. This book provides a comprehensive review on the chemistry, physics, and material applications of open-shell singlet diradicaloids. Particularly, it elaborates the fundamental structure–diradical character–electronic property relationships both theoretically and experimentally. The book has been written by leading scientists in the field from Japan, Germany, Spain, Italy, China, and Singapore.

This 1967 volume brought together knowledge concerning the triplet state and defined the problems in need of solution.
For many decades, play has been placed outside of learning spheres and only meant for children. What can be observed now is a revival of the phenomenal characteristics and potentials found in strong play experiences across life-long learning target groups and applied situations as well as broadly in the product, service and experience development industry. The effect play can have on participants and surroundings can be extremely effective. This book provides operational design guidelines on how to find strong balances in the making of specific play-based designs as well as how to involve users and stakeholders in the process of play design making. Through curious mindsets and surprising features, designers, learners and innovators are moved to new types of perspectives, approaches, beliefs and routines. This is considered to be a vital ingredient in the 21st century and of the coming decade because of rapid changes in school sectors and industry markets. This book provides frameworks and theories at a more operational level, which can guide those interested in designing for particular play experiences at a hands-on level.
This book presents a framework for integrating blended learning and massive open online courses (MOOCs) in the Indian education system. It argues that blended teaching and learning is the most suitable approach to education in a post-COVID-19 world. Drawing on case studies used in blended learning practices around the world, the book provides ample resources for beginners to improvise the spread of knowledge around information technology in higher education. It discusses various concepts such as flip learning in blended learning models and examines the self-assessment tools and structures it offers to institutions for building competencies. In addition to addressing the challenges and opport...
This invaluable book focuses on the mechanisms of formation of a solid-electrolyte interphase (SEI) on the electrode surfaces of lithium-ion batteries. The SEI film is due to electromechanical reduction of species present in the electrolyte. It is widely recognized that the presence of the film plays an essential role in the battery performance, and its very nature can determine an extended (or shorter) life for the battery. In spite of the numerous related research efforts, details on the stability of the SEI composition and its influence on the battery capacity are still controversial. This book carefully analyzes and discusses the most recent findings and advances on this topic.
Gayle Y. Iwamasa and Pamela A. Hays show mental health providers how to integrate cultural factors into cognitive behavior therapy (CBT). They describe the application of CBT with clients of diverse cultures and discuss how therapists can refine CBT to increase its effectiveness with clients from a variety of cultural backgrounds. Contributors examine the unique characteristics of CBT and its use with various racial, ethnic, and religious minority groups in the United States. Strategies for using CBT with older adults; individuals with disabilities; and lesbian, gay, bisexual, transgender, queer, and questioning clients are also examined. A chapter on culturally responsive CBT clinical supervision closes the volume. This new edition includes updated demographic information, a greater emphasis on culture-specific assessments, and a new chapter on using CBT with clients of South Asian descent. -- Résumé de l'éditeur.
