One area of organometallic chemistry that has attracted great interest in recent years is the syntheses, characterization and study of organometallic complexes conjugated to biomolecules with different steric and electronic properties as potential therapeutic agents against cancer and malaria, as antibiotics and as radiopharmaceuticals. This minireview focuses on the unique structural diversity that has recently been discovered in α- amino acids and the reactions of metallocene complexes with peptides having different chemical behavior and potential medical applications. Replacing α-amino acids with metallocene fragments is an effective way of selectively influencing the physicochemical, structural, electrochemical and biological properties of the peptides. Consequently, research in the field of bioorganometallic chemistry offers the opportunity to develop bioactive metal compounds as an innovative and promising approach in the search for pharmacological control of different diseases.

Written in a clear, accessible style, this book covers the fundamental aspects of soil science with an emphasis on topics useful to landscape architects and professionals in related fields. The book begins with a discussion of soil surveys developed in different countries, followed by a concise description of soil components and how the interactions between air, water, and nutrients affect plant growth. It examines methods for controlling erosion, particularly in light of modern irrigation techniques. It describes the chemistry of plant growth, devotes four chapters to macro- and micro-nutrients, and features a detailed discussion of ways to diagnose and correct plant disorders. It also looks at the engineering aspects of soils and includes a detailed list of references for further information. Written by an experienced teacher with an extensive background in landscape architecture, this volume will be an invaluable source for students and researchers in architecture, horticulture, and urban planning.
