German-Ukrainian Network for Digital Innovation
Німецько-український проєкт, що дає можливість реалізувати інноваційні ідеї студентів
Role: Project manager
Olena Goncharuk
D.Sc., Senior Researcher
Description of the field of scientific research:
Olena heads the research project “Biocompatible Hybrid Hydrogels with Functional Inorganic Fillers to Enhance Plant Vegetation” within the framework of the US National Academy of Sciences Support Program for Ukrainian Scientists in cooperation with PAN. The project aims to develop hybrid materials to restore degraded soils and soils affected by military contamination.
List of duties:
Peculiarities of physical and chemical processes at the solid/liquid and solid/gas interfaces, namely the influence of the structure of high-surface oxides on the adsorption of low- and high-molecular-weight compounds, the formation of surface charge and double electric layers in aqueous medium, the dependence of the enthalpy of interaction of polar and non-polar substances on the type and concentration of surface-active centers of nanoxides. The research priorities also include:— Determining the relationship between physical and chemical processes at the interface and such properties of aqueous and non-aqueous dispersions as aggregation and sedimentation stability, rheology, particle size distribution, zeta potential, etc.— Studying the effect of synthesis and modification methods on the morphology and structure of individual and mixed nanoxides obtained by pyrogenic and nanocarrier deposition methods, and determining their impact on the general properties of dispersions.— Study of the influence of nanoxides on the structure and functional properties of their composites with natural (polysaccharides) and synthetic (N-isopropyl acrylamide) polymers.— Synthesis and study of the structural and functional properties of hydrogels crosslinked/filled with inorganic nanoparticles.— Development of hydride organic-inorganic materials for sorption and prolonged release of immobilized substances.
Professional experience:
From 1998 to 2004 she worked as a graduate student, leading engineer at the Chuiko Institute of Surface Chemistry of the National Academy of Sciences of Ukraine, from 2004 to 2007 - a junior researcher at the Chuiko Institute of Surface Chemistry of the National Academy of Sciences of Ukraine, from 2007 to 2009 - a researcher at the Chuiko Institute of Surface Chemistry of the National Academy of Sciences of Ukraine. From 2009 to 2018, she was a Senior Researcher at the Department of Amorphous and Structurally Ordered Oxides at the Chuiko Institute of Surface Chemistry of the National Academy of Sciences of Ukraine, and from 2018 to 2020, she was a doctoral student at the Ovcharenko Institute of Biocolloidal Chemistry of the National Academy of Sciences of Ukraine.
From January 2021 to the present, she has worked as a Senior Research Scientist at the Department of Functional Hydrogels at the Ovcharenko Institute of Biocolloidal Chemistry of the National Academy of Sciences of Ukraine. And from September 2021 to June 2024, she was a professor at the Igor Sikorsky Kyiv Polytechnic Institute, Department of Chemical Technology of Ceramics and Glass.
The scientist is also a reviewer for international professional journals, including the International Journal of Biological Macromolecules and Applied Nanoscience.
In the Frontiers in Chemistry project, she is the editor of the topic: Unveiling Mechanisms at Solid/Solution Interfaces: Towards Advanced Material Applications.
