Abstract: Disclosed herein is a solid composition for oral care comprising at least one whitening agent chosen from chloride isocyanurate and metal salts of hypochlorite; at least one carbonate base; and optionally at least one effervescent acid. Further disclosed herein is a kit comprising the solid composition and an aqueous liquid composition, as well as methods of whitening teeth and/or producing antibacterial effects in the oral cavity comprising mixing the solid composition with an aqueous liquid composition until the solid composition disintegrates to create a mouthwash comprising hypochlorite; and contacting teeth with the mouthwash comprising hypochlorite.

Abstract: Disclosed is a method of forming a uniform coating onto a tooth surface, which method includes: forming droplets by spraying an orally acceptable coating material through a spray nozzle, and depositing the droplets onto the tooth surface to thereby form a uniform coating. In the method, the droplets have a volume-averaged droplet size of about 1 ?m to about 100 ?m, a spray including the droplets travels from a tip of the spray nozzle towards the tooth surface at a spray rate of less than about 10 milliliters/minute, and the droplets include a film-forming polymer, a therapeutic agent and/or a cosmetic agent.

Abstract: Disclosed in certain embodiments is a composition comprising a biological material and transition metal atoms selected from the group consisting of Group IVB, Group VB, Group VIB of the Periodic Chart and a combination thereof, bound to a surface of the biological material.

Abstract: A dye-free nail varnish that is used alone or with a stamp to generate a colored coating under incident white light is presented. The nail varnish includes photonic particles and/or block copolymers that can self-assemble to provide a structurally colored coating. The stamp presents a pattern of repeating nanostructures that can be transferred by imprinting the stamp on a coating of a dye-free nail varnish, thereby providing a structurally colored nail varnish coating. Thus, the nail varnish and stamp, independently or together, provide structurally colored coatings without the use of dyes or pigments.

Abstract: The invention relates to a device for optical examination of a specimen with a cryo-immersion objective, having a stative, to which the cryo-immersion objective is fixed, wherein the cryo-immersion objective has a plurality of optical components, in particular lenses, and wherein the cryo-immersion objective has an optical front component which is in contact during operation with a coolable immersion liquid, having a specimen carrier for a specimen to be examined, having means for providing a cooled immersion liquid between the optical front component and the specimen to be examined on or against the specimen carrier. The device is characterized in that insulating means are present for interrupting a heat transition between the stative and the optical front component.
