In this volume, we included information about the preparation, characterization and applications of magnesium stearate, cobalt stearate and copper stearate, and the water sorption of polyvinyl chloride-luffa cylindrica composites. The control of the particle size and purity of nano zinc oxide, hyaluronan — an information rich messenger reporting on the physiological and pathophysiological status of synovial joints are also discussed. Further information is included as well, such as the surface properties of polyimide copolymers; polyvinylchloride antibacterial pre-treated by barrier plasma; new types of ethylene copolymers on the base nanocomposite; the interaction of hybrid antioxidants — ichphans with erythrocyte membrane; and changes in the structural parameters and molecular dynamics of polyhydroxybutyrate-chitosan mixed compositions under the external influences and antifungal activity of animated chitosan against three different fungi species. We collected the reviews and original papers about the collagen modified hardener for melamine-formaldehyde adhesive for increasing the water-resistance of plywood, including: the possibile applications of collagen colloid from secondary raw materials as a modifier of polycondensation adhesives; preparation and properties of animal protein hydrolysates for optimal adhesive compositions; a novel supramolecular hyaluronan/polyborate system for tumour treatment with boron neutron capture therapies; the analysis of the common factors of inactivation and stabilization of glutathione peroxidase I with the use of polyacrylic acid as a way of receiving preparations for curing diseases of the central nervous system and a comparison of two bioremediation technologies for oil polluted soils.
