Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include one or more UV-C light sources which irradiate contaminants as air flows through the UV-C unit. The UV-C unit is mounted on either a universal mounting mechanism or a mobile support unit to provide mobility to the UV-C unit.

The present disclosure relates to a composite film made of at least LCP and a fiber fabric, for example presenting a thickness of less than 0.10 mm, as well as articles comprising such composite films, exhibiting low dielectric constant and dissipation factors and being suitable for mobile electronic device components, for example flexible printed circuit board (FPC).

Proposed is a dielectric material of a liquid-crystal polymer composition including a low-dielectric and high-heat-dissipating liquid-crystal-material monomer for a millimeter wave band and a polymer thereof, and more particularly, a liquid-crystal polymer composition including a low-dielectric and high-heat-dissipating liquid-crystal-material monomer for a millimeter wave band and a polymer thereof, the liquid-crystal-material monomer including a mesogen core, a silane-based group, and a polymerization reactive group.
