Документ Superhydrophobic textiles with fibers coated by nanosctructured indium-doped zinc oxide layers(Kamianets-Podіlskyi National Ivan Ohiienko University, 2020) Klochko, N. P.; Khrypunova, I. V.; Klepikova, K. S.; Kopach, V. R.; Zhadan, D. O.; Petrushenko, S. I.; Dukarov, S. V.; Lyubov, V. M.; Kirichenko, M. V.Документ Wettability of the cotton and polyester tissues coated by nanostructured indium-doped zinc oxide layers(Ivan Franko National University of Lviv, 2020) Klochko, N. P.; Khrypunova, I.

R.; Dukarov, S. V.; Sukhov, V. M.; Kirichenko, M. V.; Khrypunova, A. L.In this work, we used the low temperature solution growth Successive Ionic Layer Adsorption and Reaction (SILAR) for a deposition of the nanostructured undoped and indium doped (ZnO and ZnO:In) thin films on flexible polyimide (PI) substrates for their use as cheap non-toxic thermoelectric materials in the flexible thermoelectric modules of planar type to power up portable and wearable electronics and miniature devices. The use of a zincate solution in the SILAR method allows to obtain ZnO:In film, which after post-growth annealing at 300 ◦C has low resistivity ρ ≈ 0.02 Ω m, and high Seebeck coefficient 147 μV/K and thermoelectric power factor at near-room temperatures. As evidence of the operability of the manufactured films as the basis of the TE device, we have designed and tested experimental lightweight thin-film thermoelectric module. This TE module is able to produce specific output power 0.8 μW/m2 at ΔT = 50 K.Документ Near Ultraviolet Photodetector Based on Electrodeposited in Pulse Mode Zinc Oxide Arrays(Institute of Electrical and Electronics Engineers, 2016) Klepikova, K.

V.Документ Zinc oxide-nickel cermet selective coatings obtained by sequential electrodeposition(Elsevier, 2015) Klochko, N. P.; Klepikova, K. S.; Tyukhov, I. I.; Myagchenko, Y. O.; Melnychuk, E. E.; Kopach, V. R.; Khrypunov, G. S.; Lyubov, V. M.; Kopach, A. V.; Starikov, V. V.; Kirichenko, M. V.The investigation of pulse electrodepositing modes influence on crystal structure, morphology and optical properties of ZnO has revealed the conditions in which quasi-one-dimensional (1D) ZnO nanorod arrays are formed as separate nanorods. Due to a sufficiently high resistance of zinc oxide, the electrodeposition of nickel on the fluorine doped tin oxide (FTO)/ZnO surfaces carried out in space between the ZnO nanorods. An incomplete filling of the gaps between nanorods by the nickel nanoparticles through subsequent Ni electrodeposition ensured the creation of ZnO–Ni graded cermets. The cermets, in which electrochemical filling of the spaces between ZnO nanorods by Ni, was performed in the pulse mode. It provided higher absorption of visible and near IR light. It was shown that the manufactured ZnO–Ni graded cermets have high light absorption combined with comparatively low thermal losses, so these cermets are promising cheap and affordable selective coatings for solar heat collectors.Документ Influence of UV light of extraterrestrial solar irradiance on structure and properties of ZnO films prepared through pulsed electrochemical deposition and via SILAR method(Сумський державний університет, 2018) Klochko, N. P.; Klepikova, K. S.; Petrushenko, S. I.; Kopach, V. R.; Khrypunov, G. S.; Zhadan, D. O.; Dukarov, S. V.; Lyubov, V. M.; Kirichenko, M. V.; Surovitskiy, S. V.; Khrypunova, A. L.The investigations of effect of long-wave (UVA) and short-wave (UVC) ultraviolet light of extraterres-trial solar irradiance on the nanostructured zinc oxide arrays, which were grown by pulsed electrodeposition, as well as on the ZnO and ZnO:In films produced by Successive Ionic Layer Adsorption and Reaction technique (SILAR) confirmed their suitability as UVA-active photosensitive materials. The crystal structure, surface morphology, chemical composition and optical properties found no obvious significant destructive changes after UVC irradiation. However, we detected some irreversible changes in the nature of point defects under the influence of UVC, which affect the ZnO and ZnO:In resistivity, activation energy, photosensitivity and thermoelectrical properties.
