Bryukhanov V.V., Tikhomirova N.S., Gorlov R.V., Slezhkin V.A.Interaction of surface plasmons of silver nanoparticles on silochrom and rough solver films with elektronno-induced adsorbates of rhodamine 6G molecules (Abstract)
It has been found that in the synthesised hydrosol of silver plasmon resonance on two lengths of waves – λ=265 and λ=430,9 nm has. It has been observed that the presence of silver nanoparticles on a surface of silochrom increases the fluorescence of rhodamine 6G molecules. Fluorescence enhancement rhodamine 6G molecules in a matrix of polyvinyl spirit on the silver films received by electrodeposited reduction has been investigated. It is found that on continuous silver films it is manifested plasmon resonance on frequency of 400 nm.

Karstina S.G.Influence of molecular matrix structural organization on processes of absorbent molecules stable fractal clusters development (Abstract)
By the methods of computer moderating and multifractal analysis are researched processes of local fractal structures at intermolecular interactions in adsorbed on heterogeneous porous surface of molecular layer. It is shown, that formation of stable molecular structures are accompanied by changes of generalized fractal dimensions, ordering of the matrix, rate of entropy change and rate coefficients of reactions. Nature of these parameters depend on initial distribution of interacting molecules, probability of interaction, initial ordering of matrix and its temperature. The derived results in work are confirmed by experimental data on change in luminescence decay kinetics in formation in adsorbed layer of molecular clusters in the electron excitation energy transfer and annihilation.

Efremenko Y., Mezenova O.Assessment of possibility and prospects of application of multisensory systems for determination of fish freshness degree (Abstract)
During fish storage its chemical composition is changing, resulting in the fish accumulate new substances that significantly alters the sensory properties and nutritional value of meat. For assessing of the fish quality has priority use sensory characteristics, but they are mainly characterized by the descriptive terminology and allow the possibility of broad interpretation of the wordings that does not allow an objective assessment of quality. Elaboration of reliable methods for identification and organization of control of these substances is possible with the use of multisensor systems for solving problems associated with the establishment of qualitative and quantitative composition of volatile substances that form the smell of stale fish.
