Optical property of nonmaterial is the most prominent and widely investigated property. Both metal and semiconductor nanostructures show optical spectra though their underlying physics is different. Metal nanostructures show absorption spectra due to excitation of Plasmon and semiconductor nanostructures absorb incident radiation to transit from lower to higher energy state. Proper tuning of the shape, size, crystallinity and adsorbed surfactant leads to varied absorption and emission spectra which is prior criterion for suitability of their application in different devices. In this book, various nanocrystals are synthesized by one pot polymer assisted hydrothermal process. Their characterization and optical property is discussed in detail. Application of the synthesized nanomaterials are also demonstrated.

The book deals with the pricing of ecosystem services provided by agriculture. All provisioning, regulating, supporting and cultural services are being covered in this title. Chapters in this contributed volume cover topics such as pricing of services from the soil, water, and nutrient management. Quantified monetary values of carbon sequestration and renewable energy applications in agriculture are covered with clear-cut methodologies. This book also links ecosystem service-based pricing with crop insurance. Improving the farmers' livelihood is the central goal of the agricultural production system throughout the world. Under the climate change context, farms' produce is now climate-vulnerable and heavily dependent on weather conditions. Moreover, we often neglect the contribution of several positive impacts of agricultural practices on ecosystems and natural resources. Therefore, there is a need to quantify and value these ecosystem services in agriculture. However, valuation and pricing the services in agriculture both tangible and intangible is a challenge. It is necessary to have clear-cut methodologies for pricing ecosystem services of agriculture in terms of net monetary benefits. The ecosystem service-based pricing could be a solid basis for calculating the insurance to farmers in case of occurrence of natural hazard and associated crop damage.This book is of interest to scholars, teachers, researchers, environmental scientists, watershed managers, capacity builders, and policymakers. The book also serves as effective reading material for undergraduate and graduate students of agriculture economics, ecology, agronomy, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be useful.
