Description

Application

• Preparation and application of naringenin imprinted cryogel membranes for selectively separation of naringenin from natural environment: This study focuses on using 2-hydroxyethyl methacrylate as a co-monomer in cryogels designed for specific molecule adsorption from natural sources (E Demirtaş, M Odabaşı - 2024, Springer).
• Metallization of polypropylene substrates through surface functionalization and physical vapor deposition of chromium coatings: Investigates the enhancement of adhesive properties on polypropylene substrates using 2-hydroxyethyl methacrylate, advancing material engineering and surface treatments (N Fumagalli et al., 2024, Elsevier).
