Microhardness and wear behavior of nanodiamond‐reinforced nanocomposites for dental applications

Polymer Composites, Volume 46, Issue 3, Page 2292-2303, 20 February 2025.
Dental resins reinforced with nanodiamond particles for improved wear and microhardness properties. Abstract In polymer‐based dental composites, wear is a three‐body wear system mainly abrasive, because of the food particles and wear products suspended in the oral cavity, which are transferred to the microcavities of the surface of the replacements ...

Poly(methyl methacrylate) - Palladium clusters nanocomposite formation by supersonic cluster beam deposition: a method for microstructured metallization of polymer surfaces [PDF]

, 2009
Nanocomposite films were fabricated by supersonic cluster beam deposition (SCBD) of palladium clusters on Poly(methyl methacrylate) (PMMA) surfaces. The evolution of the electrical conductance with cluster coverage and microscopy analysis show that Pd cluster are implanted in the polymer and form a continuous layer extending for several tens of ...

Food packaging solutions in the post‐per‐ and polyfluoroalkyl substances (PFAS) and microplastics era: A review of functions, materials, and bio‐based alternatives

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 1, January 2025.
Abstract Food packaging (FP) is essential for preserving food quality, safety, and extending shelf‐life. However, growing concerns about the environmental and health impacts of conventional packaging materials, particularly per‐ and polyfluoroalkyl substances (PFAS) and microplastics, are driving a major transformation in FP design.
