Focusing on the phenomena of photoelectret, this book explores the polarization characteristics and optimal conditions for maximum polarization in specific polycrystalline inorganic composites. It examines photoconductivity, detailing the nature of traps and recombination centers, as well as the Fermi level's position. Additionally, electroluminescence studies investigate the effects of voltage, frequency, and other physical parameters. The book also analyzes changes in conductance, capacitance, and loss factors under different conditions, providing explanations aligned with existing theories.

Focusing on the preparation and characterization of Semiconductor Nanoparticles, this book explores materials like CdS, ZnO, and CdSe using chemical synthesis methods. It details the use of techniques such as XRD, UV-VIS, SEM, and TEM for characterization. The study examines the optical and electrical properties of these nanomaterials under varying conditions, including frequency and excitation wavelength, while analyzing related properties like permittivity and conductivity. The findings are explained in the context of existing theories, providing a thorough understanding of the phenomena.

Scientific Essay from the year 2014 in the subject Biology - Botany, , language: English, abstract: Jatropha curcas L. (Euphorbiaceae) is a multipurpose perennial shrub/small tree, native to Mexico and Subtropical America, now grows naturally in most tropical areas of the world. It is an underutilized plant of multiple values. It is cultivated for seeds, having liquid biofuel potential and as live fence for the protection of agricultural crops. Various parts of the J. curcas are globally used for healthcare management of plants, human being and domesticated animals. Besides ethnomedicinal usages, this species have much other ethnobotanical, economic and ecological importance. Present book deals with origin and distribution, taxonomic description, propagation and cultivation, utilization, pharmacological activities, phytochemical properties and future prospective of this species.
