The development of durable and eco-friendly coatings with excellent adhesion and remarkable surface properties remains a critical pursuit in various industries. This study introduces an innovative methodology for the synthesis of glycidyl methacrylate--fluorinated methacrylate (P(GMA--FMA)) random copolymers with variable fluorine contents derived from GMA and FMA monomers. The copolymerization of these constituents yields coatings with enhanced durability and unique surface characteristics.

It is demonstrated that the oligomers, especially the ones terminated with CF moieties, can be employed as safer replacements to long-chain perfluoroalkyl substances/additives. The FOPU macromolecules, when added to an engineering thermoplastic (polyethylene terephthalate, PET) film, readily migrate to the film surface and bring significant water and oil repellency to the thermoplastic boundary.

Namely, by taking advantage of the structure and behavior of original oleophobic perfluoropolyether (PFPE) methacrylate (PFM) molecular bottlebrush (MBB) additive we obtained polymeric surfaces with oil contact angles well above 80° and surface energy on the level of 10 mN/m. Those angles and surface energies are the highest and the lowest respective values reported to date for any bulk solid flat organic surface not containing LCPFA.

Introduction: General practitioners'(GPs) role is important as they are easily accessible especially for elderly. Young GPs need to improve their attitudes toward the elderly so that they can be a part of solution for health problems of elderly in the future. The aim of this study is to determine attitudes of young GPs toward elderly by the University of California at Los Angeles Geriatrics Attitude Scale (UCLA-GAS).

We report a case of Brucella prosthetic mitral valve endocarditis and glomerulonephritis that could be managed by using only antibiotic therapy, including rifampicin, doxycycline and ceftriaxone, without a surgical procedure.
