    Abstract: Process for the impregnation of a polymer substrate including at least one polymer, which comprises putting said polymer substrate in contact with at least one aqueous emulsion, preferably an aqueous microemulsion, including at least one organic additive. The impregnated polymer substrate obtained from said process can be advantageously used for obtaining polymer end-products having improved aesthetic characteristics (for example, impregnation with at least one dye) or stability characteristics (for example, impregnation with at least one stabilizer), which can be used in various fields such as, for example, the optical field (e.g., advanced optical components, laser applications), the medical field (e.g., the release of pharmaceutical substances), the agricultural field (e.g., release of pesticides), fragrances (e.g., release of fragrances). More specifically, said polymer substrate can be used in luminescent solar concentrators (LSCs) which, in their turn, can be advantageously used together, for example, with photovoltaic cells (or solar cells), or photoelectrolytic cells, in solar devices (i.e. devices for exploiting solar energy). Furthermore, said luminescent solar concentrators (LSCs) can be advantageously used together, for example, with photovoltaic cells (or solar cells), in photovoltaic windows.

    Abstract: Various embodiments disclosed relate to melt-stabilized materials including ultra high molecular weight polyethylene (UHMWPE), methods of making the same, and medical implants including the same. In various embodiments, the present invention provides a method of melt-stabilizing a material including UHMWPE. The method includes obtaining or providing a solid material including UHMWPE including a first concentration of free-radicals. The method includes coating at least part of the solid material with a liquid composition including at least one antioxidant, to provide a coated solid material. The method includes heating the coated solid material in an environment including oxygen, the heating being sufficient to melt at least part of the UHMWPE, to provide a heated material. The method also includes solidifying the heated material, to provide a melt-stabilized material including UHMWPE including a second concentration of free-radicals, wherein the second concentration of free-radicals is less than the first concentration of free-radicals.
