The ENDOR techniques, of course, are not confined to studies of transition metal complexes. A fast growing interest on electron nuclear double and multiple resonance experiments is also noticed in other fields of natural sciences, such as radical, radiation and polymer chemistry, solid state physics, biophysics and mineralogy.

Foam films are usually used as a model in the study of various physicochemical processes, such as thinning, expansion and contraction of films, formation of black spots, film rupture, molecular interactions in films. Thus, it is possible to model not only the properties of a foam but also the processes undergoing in it. These studies allow to clarify the mechanism of these processes and to derive quantitative dependences for foams, O/W type emulsions and foamed emulsions, which in fact are closely related by properties to foams. Furthermore, a number of theoretical and practical problems of colloid chemistry, molecular physics, biophysics and biochemistry can also be solved. Several physico-technical parameters, such as pressure drop, volumetric flow rate (foam rotameter) and rate of gas diffusion through the film, are based on the measurement of some of the foam film parameters. For instance, Dewar [1] has used foam films in acoustic measurements. The study of the shape and tension of foam bubble films, in particular of bubbles floating at a liquid surface, provides information that is used in designing pneumatic constructions [2], Given bellow are the most important foam properties that determine their practical application. The processes of foam flotation of suspensions, ion flotation, foam accumulation and foam separation of soluble surfactants as well as the treatment of waste waters polluted by various substances (soluble and insoluble), are based on the difference in the compositions of the initial foaming solution and the liquid phase in the foam. Due ro this difference it is possible to accelerate some reactions (foam catalysis) and to shift the chemical equilibrium of some reactions in the foam. The low heat... 

Nevertheless liposomes are considered as suitable system, tor the study of biological membranes, and can easily reproduce some of their most important properties. They have been used in a wide range of applications as substrate for practically all the basic sciences (physics, biophysics, physical chemistry, chemistrv, pharmaceutics and medicine)... 

This book summarizes NMR research results collected over the past three decades that are related to very different materials, from nanomaterials and nanocomposites to biomaterials, cells, tissues, seeds, etc. It will primarily be of interest for PhD students and young scientists, although it may also prove useful to specialists and experts working on adsorption, adsorbent synthesis, surface chemistry, surface physics, biophysics, cryopreservation, and other related fields.

As the foundation of quantum statistical mechanics, the theory of open quantum systems has remained an active topic of research since about the middle of the last century [1-40]. Its development has involved scientists working in fields as diversified as nuclear magnetic resonance, quantum optics and nonlinear spectroscopy, solid-state physics, material science, chemical physics, biophysics, and quantum information. The key quantity in quantum dissipation theory (QDT) is the reduced system density operator, defined formally as the partial trace of the total composite density operator over the stochastic surroundings (bath) degrees of freedom. 

Three branches of science deal with colloids and macromolecules colloid science, surface science, and macromolecular science. CoUoid science is the study of physical, mechanical, and chemical properties of colloidal systems. Surface science deals with phenomena involving macroscopic surfaces. Macromolecular science investigates the methods of syntheses in the case of synthetic polymers (or isolation and purification in the case of natural products such as proteins, nucleic acids, and carbohydrates) and the characterization of macromolecules. It includes, for example, polymer chemistry, polymer physics, biophysical chemistry, and molecular biology. These three branches of science overlap. What one learns from one branch can often be apphed to the others.
