Abstract:
A light directing article comprises an acrylic polyvinyl acetal film to protect the optical elements of the light directing article. The acrylic polyvinyl acetal film has a Tg of at least 30°C and comprises a (meth)acrylic polymer and polyvinyl acetal polymer. The acrylic polyvinyl acetal film is flexible and durable to mechanical deformation.
Abstract:
An etched dielectric film for use in microfluidic devices. Channels, recesses, and other features can be etched into the films to make them suitable for use in microfluidic devices.
Abstract:
Metal matrix composite wires (59) that include at least one tow comprising a plurality of substantially continuous, longitudinally positioned fibers (51) in a metal matrix. The fibers are selected from the group of ceramic fibers carbon fibers, and mixtures thereof. The wires have certain specified characteristics such as roundness values, roundness uniformity values, and/or diameter uniformity values.
