In this volume, we included information about the preparation, characterisation 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 anti-fungal 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 stabilisation 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.
