    Solid oxide cells (SOCs) can operate efficiently in solid oxide fuel cell (SOFC) and/or solid oxide electrolysis cell (SOEC) modes, and are one of the most promising electrochemical devices for energy conversion and storage, facilitating the integration of renewable energies with the electric grid. However, the SOC electrodes suffer performance and stability issues, especially in the case of fuel electrodes when SOCs are fueled by cheaper and more available fuels such as methane and natural gas. Typical Ni-YSZ cermet fuel electrodes suffer problems of coarsening, carbon deposition, and sulfur poisoning. Therefore, developing new electrodes using novel design strategies for SOCs is crucial. In this review work, the fuel electrode development strategies including the in situ exsolution of nanoparticles, multi-elemental nanocatalysts, and nanofiber materials have been reviewed and summarized for the design of new electrodes for SOCs. Nanofiber electrodes with in situ exsolved nanoparticles, which combine the advantages of a unique nanofiber microstructure and stable and active exsolved nanoparticles, are of great interest and significantly contribute to the development of high-performance fuel electrodes for SOCs.

    Overview of the nanoparticles application for reservoir engineering and Enhanced Oil Recovery (EOR) methods
    (Wydawnictwa AGH, 2018) Kulinič, Vitalij; Pikłowska, Anna; Kulìnič, Oleg Anatolìjovič
    The scientific aim of the paper is the characteristics of various types of nanoparticles, their physical and chemical parameters. In the article authors give examples of various nanoparticles used in reservoir engineering and EOR methods. The results of laboratory measurements of the impact of nanoparticles on the change of reservoir parameters and the increase of oil recovery of sandstones and carbonates are presented. In the article have been shown the possibilities of using nanotechnology, including the achievements of different authors. It presents a general literature review of modern research methodologies of nanoparticles in the global oil industry.
