This timely volume addresses issues pertaining to language teaching, learning and research during the pandemic. In times of a global emergency, the aftermath of emergency remote teaching (ERT) cannot be ignored. The question of how language educators and researchers unleash creativity and employ strategies vis-a-vis ERT still remains to be answered. With practitioners in mind, it covers a broad spectrum of educational settings across continents, target languages and methodologies. Specifically, it reveals viable ways of utilizing digital technologies to bypass social distancing while highlighting the pitfalls and challenges associated with crisis teaching and research. This volume comprises two parts: Teacher Voice vicariously transports readers to practitioners' compelling stories of how teacher resilience, identity and professional development are crystallized in adaptive pedagogy, online teaching practicum, virtual study programs and communities of practice during ERT. The second part, Researcher Corner, showcases innovative approaches for both novice and seasoned researchers to upskill their toolkits, ranging from case study research and mixed methods designs, to auto- and virtual ethnography and social media research. The array of food for thought provides a positive outlook and inspires us to rethink our current practices and future directions in the post-COVID world. Regardless of their backgrounds and experiences, readers will be able to relate to this accessible volume that harmonizes research and practice, and speaks from the hearts of all the contributors.

Due to its nondestructive imaging power, scanning tunneling microscopy has found major applications in the fields of physics, chemistry, engineering, and materials science. This book provides a comprehensive treatment of scanning tunneling and atomic force microscopy, with full coverage of the imaging mechanism, instrumentation, and sample applications. The work is the first single-author reference on STM and presents much valuable information previously available only as proceedings or collections of review articles. It contains a 32-page section of remarkable STM images, and is organized as a self-contained work, with all mathematical derivations fully detailed. As a source of background material and current data, the book will be an invaluable resource for all scientists, engineers, and technicians using the imaging abilities of STM and AFM. It may also be used as a textbook in senior-year and graduate level STM courses, and as a supplementary text in surface science, solid-state physics, materials science, microscopy, and quantum mechanics.
