Issues concerned with the energy conversion of exothermal heterophase processes are discussed using the physico-chemical interaction between ZrO 2-Y 2 O 3 (3 mol %) nanopowder system and atmospheric moisture as an example. The electrical properties of an experimental sample are investigated upon moisture saturation in the case of a molecular-flow density gradient. A probable mechanism for the effect based on the theory of contact phenomena in semiconductors is proposed. The idea of developing chemical-electric converters fabricated from nanoscale materials with dielectric conduction is suggested.

Based on the example of a nanopowder system ZrO 2-3% mol Y 2 O 3 with atmospheric humidity interaction, the possibility of exothermic heterophase electrochemical energy conversion to electric energy is shown. Electrical properties and structure of the experimental sample were studied under gradient molecular flux density of humidity during sample saturation. The idea of development of the novel chemo-electronic converter device based on nanoscale dielectrics as ZrO 2-3% mol Y 2 O 3 is proposed.

T HE DEVELOPMENT of modern bio-nanoelectronic technologies requires new hybrid organo-inorganic systems that have a specific functional purpose and allow work in the tissues of living organisms. The practical realization and scientific study of a hybrid twocomponent system in the form of DNA molecule fragments and nanoparticles of biocompatible ceramics was the goal of this work. The interaction of a DNA molecule with nanoparticles of a solid solution of the composition ZrO 2-3mol% Y 2 O 3 (YSZ) was studied using Raman scattering and transmission electron microscopy. Samples of YSZ oxide and hydroxide were investigated in triplicate at room temperature using LabRAM HR Evolution Horiba spectrometer and JEM 200A instrument. The effect of the force field of the surface of YSZ nanoparticles on the optical properties of the DNA molecule in the TRIS buffer solution was shown. The effects of increasing the intensity of spectral lines in the long-wavelength region 250-660 cm-1 (254 cm-1 , 322 cm-1 , 470 cm-1 , 663 cm-1). suppressing the intensity of spectral lines in the shortwave region 600-3300 cm-1 (604 cm-1 , 917 cm-1 , 951 cm-1 , 1256 cm-1 , 1302 cm-1 , 2767 cm-1 , 3180 cm-1 , 3241 cm-1 , 3285 cm-1), as well as shifting lines 519 cm-1 , 917 cm-1 , 1048 cm-1 , 1547 cm-1 and 1639 on 40-60 cm-1 in the shortwave region are established. From the standpoint of the theory of wave processes, a qualitative description of the detected Up-conversion effect was done. An assumption about the potential applicability of the YSZ nanoparticle surface-DNA nucleotide interfaces as a heterodyne frequency converter in molecular-and bio-electronic devices was made. Keywords: DNA in the electric field, immobilization of DNA molecules on the surface of semiconductors and dielectrics, Raman scattering, frequency modulation, heterodyne transfer of a frequency band, molecular electronics, bio-electronic, powder nanotechnologies.
