Dendrimers have firmly established their space in the macromolecular field since their first discovery in 1978. These monodispersed and hyperbranched macromolecules present unique properties with demonstrated potential in varied scientific disciplines. Dr. Donald A Tomalia is one of the pioneers in this area whose name is synonym for polyamidoamine (PAMAM) dendrimers, one of the most extensively investigated macromolecular architectures. In this monograph, his colleagues and friends celebrate Don's achievements and contributions to the field, on the occasion of his 80th birthday in 2018, which also coincides with the 40th anniversary of the first report on dendrimers. It provides the reader with excellent reviews on different aspects of dendritic architectures, followed by research articles that explore the state-of-the-art in synthesis, properties and varied applications, including in biology. Collectively, it provides scientists just beginning their careers, as well as firmly established ones, with the pulse of the field and inspiration to continue to explore these intriguing macromolecules.

The dendrimer is a common name of polymers which are characterised by a specific structure, although their chemical composition can be very different. Dendrimers display several characteristics which distinguish them from linear polymers. All dendrimers are synthesised by attaching branched monomers to the central core molecule. Monomers are attached layer by layer. As a result of such a synthesis, dendrimers posses plenty of terminal, reactive groups on their surface and empty internal cavities. Both of these features can be utilised. Soon after the first synthesis in mid-1980's, dendrimers have become interesting and promising molecules for pharmaceutical and technical aims. The last years brought many new facts about dendrimers impact on biological systems. Both, general toxic studies, as well as detailed research devoted to particular cellular compounds, as DNA or lipid bilayer, were carried out. New types of dendrimers were synthesised and new applications appeared.
General Biophysics, Volume I deals with the theoretical physics underlying biological phenomena and presents some pertinent experimental results. It explores the molecular foundations of biophysics, the thermodynamics of nonequilibrium systems and membrane transport, nerve impulses, and mechanochemical processes. Comprised of five chapters, this volume begins with an overview of molecular biophysics and the concept of molecular recognition, followed by a discussion of the interaction between antibodies and antigens, the primary processes that determine odor reception, and the importance of intercellular interactions in the existence and development of multicellular organisms. The next chapters explain how protein biosynthesis is regulated by molecules and how proteins are biosynthesized in eukaryotic cells, along with the application of thermodynamics to the analysis of biophysical problems and the coupling of chemical reactions near equilibrium. The reader is also introduced to the stability conditions of a steady state, the concept of entropy for an open system, the thermodynamics of the sodium pump, ionic equilibrium between sodium and potassium solutions separated by an active membrane, the conformational properties of membranes, and the general phenomenological theory of facilitated transport and the role of the carriers. The book concludes with a chapter on biological mechanochemical processes and their thermodynamics. This book is a valuable resource for physicists and biophysicists, graduate and postgraduate students having the necessary knowledge of physics, and anyone acquainted with proteins and nucleic acids.
High surface area, a microporous structure, and a high degree of surface reactivity make activated carbons versatile adsorbents, particularly effective in the adsorption of organic and inorganic pollutants from aqueous solutions. Activated Carbon Adsorption introduces the parameters and mechanisms involved in the activated carbon adsorption

The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.
