Abstract: Disclosed is a formulation comprising a copolymer comprising one or more bifunctional high refractive index first monomers comprising a high refractive index aromatic core and further comprising one or more UV- or thermally-reactive groups (A) and one or more second monomers comprising a high refractive index core and further comprising one or more groups capable of reacting to increase the solubility of the copolymer in aqueous media (B), and one or more solvents. The formulation may optionally contain additional components. Further disclosed are methods for forming optical thin films from the formulation and optical devices containing the optical thin films.

Abstract: A flavor or aroma charcoal material, such as charcoal briquets, which is formulated to include a flavor or aroma component. The charcoal material may include a smoldering agent (e.g., limestone), wood particles (e.g., sawdust), a binder, and the flavor or aroma component (herbs and/or spices). The flavor or aroma charcoal material may not be configured as a fuel charcoal material, for example, it may be substantially void of char and/or coal. In an embodiment, the flavor or aroma charcoal material may be provided as part of a blend of different charcoal materials that includes both flavor or aroma briquets in combination with fuel briquets (e.g., which fuel briquets include char and/or coal, while the flavor briquets do not). The flavor briquets provide enhanced aroma and/or flavor to the grilling experience.

Abstract: A dust cover comprises a plurality of shied plates which are equal in shape and progressively reduced in size. The shield plates are joined together such that they expand and retract along an axial direction; a linking device formed of a plurality of link rod units which have two rod members equal in length. The two rod members are pivoted together at the midpoint such that two ends of the two rod members form a pair of opening-closing arms. Two arms of each one end of each link rod unit are pivoted with two arms of other link rod unit to form two pivoting points pivoted in the lower side of the same shield plate.

Abstract: This invention is a dust-proof protection cover with connecting rods. It includes several protecting cover boards in the same shape with different sizes. The sizes of protecting cover boards are decreasing and their connection will form a structure that can expand and contract along the same axis. On the bottom board of each protecting cover board, there is a sliding trough. In addition, there is a linking device is made of many connection shafts. All these connection shafts will form a device with serial protection cover that can expand and contract.

Abstract: This invention is a dust-proof protection cover with connecting rods. It includes several protecting cover boards in the same shape with different sizes so that they are slidably engaged to each other. The sizes of protecting cover boards are decreasing and their connection will form a structure that can expand and contract along the same axis. On the bottom board of each protecting cover board, there is a sliding trough. In addition, there is a linking device is made of many connection shafts.
