Abstract: Provided is a sun protection material including a plurality of polystyrene microspheres and a plurality of refractive layers. The polystyrene microspheres have a particle size of 150 nm to 300 nm. Surfaces of the polystyrene microspheres are at least partially covered by the refractive layers. The sun protection material can scatter a light in a wavelength range between 250 nm and 400 nm. A sun protection composition containing the sun protection material also may scatter a light of a wavelength range between 250 nm and 400 nm, such that the UV protection of the sun protection composition is enhanced.

Abstract: A bidet washing apparatus attachable to a toilet bowl for cleaning one or more body parts of a user is disclosed. The apparatus can include one or more water inlets configured to supply water, and a control unit, housing one or more valves connected to the one or more water inlets, including one or more control switches configured to operate the one or more valves. The apparatus can include a nozzle assembly with at least one washing nozzle fluidically connected to at least one of the valves with one or more water tubes. The at least one washing nozzle can be positioned for directing water to the body parts of the user. The apparatus can also include a protective shield gate covering at least a portion of the at least one washing nozzle, where the protective shield gate is rotatably coupled to the bidet washing apparatus.
