Piotr Kowalczyk

Associate Professor in Physics

I am an Associate Professor in Physics with over 20 years of experience in theoretical and experimental research on nanoporous materials and interfaces. My expertise includes:

• Adsorptive gas storage (hydrogen, methane, hydrogen mixtures)
• Gas adsorption and separation (pure components and mixtures)
• Adsorption of non-electrolytes from aqueous solutions
• Porosity analysis of carbonaceous materials, silicas, clays, and natural and synthetic zeolites
• Adsorption-induced deformation of porous materials
• Separation of quantum fluid mixtures
• Hydrophobic and antifreezing surfaces
• Statistical mechanics and computer simulations of adsorption and interfacial phenomena
• Feynman path integrals
• Chemometrics, machine learning, and artificial intelligence algorithms
• Positron annihilation lifetime spectroscopy (PALS)

My major contributions to the field include the development of adsorption-induced deformation models for porous solids, algorithms for evaluating the porosity of disordered materials, Feynman path integral simulations of hydrogen storage and separation in nanoconfined spaces, and a unifying theory of non-electrolyte adsorption on porous carbons.

Currently, my research focuses on the development of a theoretical framework for PALS to study O₂/N₂ separation, the discovery of regular carbon structures using in-silico algorithms, and foundational studies on surface area evaluation using gas adsorption porosimetry.
