A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

A surface treatment method and a surface treatment device 2 for a resin vessel 1 forms a coating or performs surface modification on the surface of the resin vessel 1. In a sterilized environment as well as an environment with a pressure equal to or higher than the atmospheric pressure, a material for the coating or the surface modification is attached to at least one of an inner surface and an outer surface of the resin vessel 1, and the resin vessel 1, to which the material is attached, is irradiated with an electron beam to perform the coating or the surface modification. It is possible to form the coating or perform the surface modification on the resin vessel at a high speed.

The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.

A thermal management system that provides metal mold surface temperature control using cyclic process thermodynamics to enhance plastic material flow and curing conditions making it possible to produce resin rich molded plastic surfaces without micro cracks or fissures to which contaminant particles can adhere or to which dirt can attach.

A method of manufacturing an embossed hydrophobic covering element for construction or decoration for protecting the surface from humidity or inclement weather. This method includes preparing a mixture of water and at least one organic material in a tank in which the organic material is insoluble in water, stirring the mixture so as to disperse the organic material in suspension in water, molding the prepared and stored mixture by immersing a forming mold under vacuum inside the tank in order to form a molded element, drying and densifying the molded element under vacuum so as to obtained a dried and densified element, and fully impregnating the dried and densified element in the binder so as to form the hydrophobic covering element. The binder is of an organic material. The organic material originates from a sustainably renewable resource.
