Certain stable lipid nanoemulsions, existing in natural waters and certain artificial media, display - upon intravenous injection - a marked capability for rapid active targeting, both to tumors and to certain lesion sites. This category of lipid nanoemulsions contains no phospholipids, no proteins nor peptides, no carbohydrates, and no chemical modification of the lipophilic drugs is required; consequently it avoids various past problems reported for earlier versions of targeted nanoemulsions. The book covers in detail the underlying chemical and biochemical principles of stable lipid nanoemulsions as well as many current and potential applications in nanomedicine such as targeted chemotherapy. It is in harmony with goals of the current US National Nanotechnology Initiative, which include nanomedical approaches to drug delivery that focus on developing nanoscale particles to improve drug bioavailability i.e. often using targeted nanoparticles for delivering drugs with cell precision and less side effects. Despite the obvious practical importance to various fields including nanomedicine there is currently no comprehensive book available in the literature. The proposed book will effectively fill this gap. Detailed coverage of the underlying chemical and biochemical principles of stable lipid nanoemulsions. The book includes many current and potential applications in nanomedicine such as targeted chemotherapy. Contains 67 figures (including 13 microscope photos) and 26 tables Over 1200 literature references, many of them of very recent date.

The book serves as an introduction to the interesting field of nanoscience based on polymer and metal colloidal nanoparticles, and also presents the basic knowledge of polymer colloids preparation. It places a special emphasis on polymer, inorganic and metal nanomaterials classified as nanoparticles, nanocrystals, nanorods, nanotubes, nanobelts, etc. deals with the chemistry of the reaction approaches by which polymer and metal particles are synthesized. The book explores both organic (synthetic and natural) and inorganic materials, as well as their hybrids. It describes in detail terms, definitions, theories, experiments, and techniques dealing with synthesis of polymer and metal particles. It also discusses a variety of synthetic approaches including emulsion, miniemulsion and microemulsion approaches, homogeneous and heterogeneous nucleation approaches under mild and high temperatures. There is also a chapter on modification and passivation of colloidal particles. This book would be of interest to chemical engineers, polymer chemists, organic chemists, colloid chemists, materials scientists and nanotechnologists. Although the text discusses nanoscience and nanotechnology from the viewpoint of a chemist, it would also appeal to those just entering the field and experts seeking information in other sub-fields. Serves as a general introduction for those just entering the field and experts seeking information in other sub-fields Variety of synthetic approaches is described including emulsion, miniemulsion and microemulsion approaches, hogeneous and heterogeneous nucleation approaches under mild and high temperatures Focused on both the organic (synthetic and natural) and inorganic materials, and their hybrids

The shape of drops and bubbles is the centre of interest for many interfacial scientists. This book describes the most recent accomplishments to make use of drops and bubbles in fundamental research and application. After a general introduction into the mechanics of liquid menisci, chapters are dedicated to methods based on drops or bubbles. The chapters about the three main drop experiments provide the theoretical basis, a description of experimental set-ups, specific advantages and disadvantages, correction and calibration problems, experimental examples and their interpretation: pendent and sessile drop, drop volume, and spinning drop technique. The chapter about capillary pressure methods summarises different techniques and gives examples of applications, for instance measurements under microgravity. The maximum bubble pressure technique as a particular capillary pressure method is described, with emphasis on the most recent developments which made this technique applicable to extremely short adsorption times, down to the range of milliseconds and less. Problems connected with aerodynamics and hydrodynamics are discussed and used to show the limits of this widely used standard method. The oscillating bubble technique provides information not available by other techniques, for example about the dilational rheology of adsorption layers and relaxation processes at the interface. The description of rising bubbles in surfactant solutions will contain the hydrodynamic basis as well as the theoretical description of the effect of interfacial layers on the movement of bubbles. Besides the theoretical basis experimental data, such as water purification, flotation processes etc. and the relevance for practical applications will be presented. The chapter about lung alveols demonstrates how important bubbles built by biological membranes are in everyday life. The relevance for medicine and biology as well as model studies is discussed. An important example for the application of drops is metallurgy, where the surface tension of metals and alloys is an important parameter for many applications. The chapters on drop shape analysis by using fibre technique and on force measurements between emulsion droplets are of much practical relevance. Lists of references and symbols are given separately at the end of each chapter while a common subject index is given at the end of the book.

The third edition of Theory of Simple Liquids is an updated, advanced, but self-contained introduction to the principles of liquid-state theory. It presents the modern, molecular theory of the structural, thermodynamic interfacial and dynamical properties of the liquid phase of materials constituted of atoms, small molecules or ions. This book leans on concepts and methods form classical Statistical Mechanics in which theoretical predictions are systematically compared with experimental data and results from numerical simulations. The overall layout of the book is similar to that of the previous two editions however, there are considerable changes in emphasis and several key additions including: •up-to-date presentation of modern theories of liquid-vapour coexistence and criticality •areas of considerable present and future interest such as super-cooled liquids and the glass transition •the area of liquid metals, which has grown into a mature subject area, now presented as part of the chapter ionic liquids •Provides cutting-edge research in the principles of liquid-state theory •Includes frequent comparisons of theoretical predictions with experimental and simulation data •Suitable for researchers and post-graduates in the field of condensed matter science (Physics, Chemistry, Material Science), biophysics as well as those in the oil industry

Electrorheological (ER) and magnetorheological (MR) fluids, which can be transformed from the liquid state into the solid state in milliseconds by applying an electric or a magnetic field, are smart fluids having the potential to revolutionize several industrial sectors. The Seventh International Conference on Electrorheological Fluids and Magnetorheological Suspensions took place at a time when some MR and ER applications were beginning to appear on the market, making a notable impact on industries. Scientists and engineers in multidisciplinary areas came together to explore the state-of-the-art technology and identify thrust areas to be focused on. This volume of proceedings collects contributions from most leading experts in the field. It reviews the most recent MR and ER applications, discusses the materials technology, explores the basic science research on ER and MR fluids, and examines the novel properties of these fluids. It provides the most up-to-date and probably the best information about the area. It can serve as a stimulating and valuable reference for research workers and students in materials science, condensed matter physics, engineering, and chemistry. The valuable information not only reports on the leading edge of research and applications, but also provides an overview of the field.
