This book focuses on the latest developments in chemistry research. Chapter 1 discusses electrodeposition of composite coatings and how it's an effective method for modifying and enhancing various functional properties of coatings. Chapter 2 analyzes an ATA film that can protect a copper surface from corrosion. Chapter 3 explores visible, light-prompted, cross-dehydrogenative coupling reactions as a sustainable approach for synthesizing N-heterocycles. Chapter 4 examines the utilization of nanotechnology-based chemosensors in detecting toxic ions within the environment. Chapter 5 reports on the structural information of osilodrostat calculated by ab-initio methods. Chapter 6 provides relevant insights regarding the relationship between the supramolecular structure and in vitro digestibility, which is a relevant issue to consider when looking for possible fields of application of starch as a functional ingredient in food matrices. Chapter 7 investigates the mechanism for the acetyl transfer reaction of acetic acid catalyzed by H-ZSM-5 Zeolite. Chapter 8 discusses laser dyes (rhodamines and coumarins). Finally, Chapter 9 addresses pyrimidine analogs and their biological and medicinal potentials.
