Abstract: A flow reactor has a fluidic module with a first major outer surface. The module contains a fluid passage and has a transmittance through the first major outer surface to the fluid passage of at least 20% over a range of wavelengths. The reactor has an illumination module comprising one or more radiation sources, which can emit within the range, positioned within an enclosure. The enclosure has a back wall and a side wall and an opening opposite the back wall. An edge of the side wall surrounds the opening. The illumination module is positioned such that the opening of the illumination module faces the first major outer surface of the fluidic module. The side wall comprises a telescoping portion such that a distance from the back wall of the enclosure to the edge of the side wall is adjustable.

Abstract: Disclosed are methods for coating or decorating a surface of a glass sleeve. The methods include depositing a metal layer onto a surface of the glass sleeve by an electroless plating method. Also disclosed are glass sleeves which are coated or decorated on an internal surface, and electronic devices comprising the coated glass sleeves.

Abstract: Provided herein are sulfated compounds that are useful as high refractive index monomers for optical and other applications and methods for producing the same. The sulfated compounds are liquid at room temperature and exhibit good miscibility with other monomers. They are branched and can act as crosslinking agents, increasing the rigidity of the resulting polymers. They have low molecular weights and are useful in combinations with higher viscosity oligomers or crystalline monomers and to generate curable compositions. Also provided herein are high refractive index curable compositions produced from the sulfated compounds suitable for the production optical articles, including for coatings, gratings, and other surface features. Further provided are high refractive index nanocomposite materials made from the sulfated compounds and curable compositions. Also provided herein are articles and optical devices incorporating the curable compositions and nanocomposites described herein.
