Exciton can be regarded as an elementary excitation of condensed matter which can transport energy without transporting net electric charge. This book presents research in the study of exciton quasiparticles, including exciton polariton dispersion in multinary compounds; exciton relaxation dynamics in colloidal core and core/shell CdSe nanorods; solitons and excitons in seismotectonic problems; exciton diffusion length measured by surface photovoltage method; and, excitons in CdO parabolic quantum dots.

In the present economic, political, societal and environmental landscape, which is dominated by the COVID-19 pandemic, the emergence of challenges and issues that demand immediate and urgent responses is more intense than ever. Policymakers, international organizations, governmental and non-governmental institutions around the globe are seeking effective and sustainable policies, as they try to tackle far-reaching issues that affect all aspects of the economy and agriculture, including the food sector.
