Abstract: Systems and methods are provided for in situ observation of reservoirs, such as syringes, during the freeze thaw cycle to allow for more in depth understanding of the behavior of the system. The systems and methods may include an inert environment and/or a low concentration (e.g., on the order of parts per million (ppm)) of water, which may inhibit frost formation.

Abstract: Composite materials that include fluoropolymers. Methods of reducing friction, which may include contacting a first article and a second article that include or are formed of one or more fluoropolymers. The composite materials may include a fluorinated polymer and a first filler. The first filler may be present at an amount of about 3% to about 50%, by weight, based on the total weight of the first fluorinated polymer and the first filler.

Abstract: The present disclosure provides for mixtures, methods for making mixtures, articles, methods for making articles, and methods of using articles. In an aspect, the articles have superior tribological properties owing to combinations of polytetrafluoroethylene and an irradiated fluoropolymer described herein.

Abstract: Disclosed herein is an intervertebral disc prosthesis comprising a first cantilever arm; the first cantilever arm comprising a shaft that is affixed to a disc; a second cantilever arm that comprises a plurality of rods that contact the disc; the plurality of rods being equidistant from a central axis of the shaft; and a third cantilever arm that comprises a platform to which are attached a plurality of rings; the rings being concentrically disposed about the shaft; the rings being in operative communication with each other; where the plurality of rods contacts the platform; and where the second cantilever arm has more degrees of freedom than the first cantilever arm, while the third cantilever arm has a number of degrees of freedom that are greater than or equal to the number of degrees of the second cantilever arm.

Abstract: Embodiments of the present disclosure provide for mixtures, methods for making mixtures, articles, methods for making articles, and methods of using articles.
