SUMMARY:Advancing Technology with 2D Carbides and Nitrides (MXenes)
DESCRIPTION:Přednáška se zaměří na dvourozměrné karbidy a nitridy přechodných kovů známé jako MXeny, jejich přípravu, vlastnosti a využití v oblastech, jako jsou ukládání energie, sensing, optoelektronika, elektromagnetické stínění či tepelný management.\n\nAnnotation:\n\nMXenes are a versatile family of two-dimensional (2D) early transition metal carbides, nitrides, and related structures with a general formula of Mn+1XnTx, where M is a transition metal, X is carbon or nitrogen (oxygen substitution is possible), T represents the surface terminations (O, OH, halogens, chalcogens, etc.), and n = 1—4. More than 100 MXene compositions have been reported, and the number of possible structures continues to grow through solid solutions and controlled surface functionalization. MXenes are a rare, few-in-a-generation chemical platform, akin to metal-organic frameworks (MOFs) and quantum dots, that redefine the boundaries between molecules and materials, organic and inorganic compounds, homogeneous and heterogeneous reactivity. MXenes enable computationally guided, atomistic design of 2D materials and exhibit distinctive mechanical, tribological, electronic, optical, and electrochemical properties. Most are metallic, with a tunable density of states at the Fermi level. Their properties can be engineered through composition, surface chemistry, and ionotronic modulation, enabling advances in areas such as robotics, optoelectronics, communications, energy storage, sensing, and healthcare. In several applications—including EMI shielding and thermal management—MXenes have already demonstrated performance superior to that of conventional materials. Their combination of high mechanical strength and functional versatility supports the development of assembled, multifunctional materials with property sets not achievable in any single material. This talk will address scalable manufacturing routes from low-cost precursors, processing, development of composites, their mechanical and physical properties, and representative applications ranging from energy storage to thermal management.\n\nYury Gogotsi is a Distinguished University Professor and Bach Endowed Chair in the Department of Materials Science and Engineering at Drexel University (Philadelphia, USA). He is the founding Director of the A.J. Drexel Nanomaterials Institute. He is credited with principal contributions to developing materials for electrochemical capacitors, the discovery of a large family of 2D carbides and nitrides known as MXenes, and tuning porosity of carbide-derived carbons with sub-nanometer accuracy. He published the first microscopic observation of water inside carbon nanotubes, discovered polygonal nanotubes (graphite polyhedral crystals), and invented the field of high-pressure surface science. The impact of his work is demonstrated by over 350,000 citations. The 2024 Stanford List placed Gogotsi 21st among all scientists in all disciplines and 2nd in Nanoscience and Nanotechnology worldwide.\n\n
