Abstract:
A display apparatus includes a display module and a front case. The display module displays images. The display module includes a boss fixing member having a combination hole. The front case covers a first surface of the display module and has a first boss that is inserted into the combination hole to combine the front case to the display module. The first boss is formed at inside edges of the display module. The boss fixing member is positioned within the edges of the display module which define the outdimension of the display module.
Abstract:
In this invention, polyimidazole ligands (PILs) incorporating pendant imidazole moieties for nanocrystal binding and either sulfonatebetaine, carboxybetaine, or phosphocholinebetaine moieties for water-solubilization have been developed. Greatly enhanced stability of nanocrystals (both over time and in wide pH range) was achieved by incorporating multi-dentate imidazole moieties which provide strong coordination of the ligand to the nanocrystal surface and prevent aggregation of nanocrystals. Synthesis of betaine PILs was developed by modifying the synthesis of recently developed PEG containing poly imidazole ligands (PEG PILs). These nanocrystals are compact, water soluble, and biocompatible.

Abstract:
The present invention relates to a method of manufacture of styrene-butadiene latexes. The styrene-butadiene latex according to the present invention is characterized by having a superior adhesive force as the formation of films at an early stage is promoted by adjusting the gel content and molecular weight of the outermost layer, as well as a fast ink-drying speed and a high air permeability as the formation of paper films is maintained. It may be applied to paper coating very stably since the mechanical stability and chemical stability of the latex are superior.
