His work focuses on reducing friction and wear in hard contact situations, which is crucial for various applications, including watchmaking.

Latest Patents

Bielecki holds a patent for a groundbreaking invention titled "Lubrication with oil-compatible polymer brushes." This patent presents a polymer-brush-based strategy aimed at enhancing friction and wear reduction under boundary-lubrication conditions, specifically in non-aqueous environments. The invention utilizes Surface-initiated Atom Transfer Radical Polymerization (SI-ATRP) to synthesize three different oil-compatible, hydrophobic polymer brushes based on alkyl methacrylates. The study details polymerization kinetics, chemical characterization through Fourier transform infrared spectroscopy (FTIR), and surface morphologies observed via atomic force microscopy (AFM). The lubrication properties of these anchored polymers were evaluated using ball-on-disk methods and lateral force microscopy (AFM/LFM), demonstrating a significant reduction in friction under contact pressures as high as 460 MPa. The compatibility of the polymer with the lubricating fluid plays a crucial role in the frictional response, and the results indicate promising tribological performance with watchmaking lubricants.

Career Highlights

Bielecki is currently employed at The Swatch Group Research and Development Ltd., where he continues to explore advancements in lubrication technologies.
