This technology is directed to the preparation of doped-bismuth-silicate seed crystals through controlled crystallization (e.g. dimensionality of growth and nucleation mechanism) and the method of forming high purity single seed (particle size ranges from micrometers to millimeters) for various uses. These seed crystals have a nominal stoichiometry of Bi.sub.2-xA.sub.xSiO.sub.5, Bi.sub.2-xA.sub.xSi.sub.3O.sub.9, Bi.sub.4-xA.sub.xSi.sub.3O.sub.9, and Bi.sub.12-xA.sub.xSiO.sub.20, where A is a rare earth dopant selected from La, Ce, Nd, Pr, and/or Sm.

A polarizing plate and an optical display including the same are provided. A polarizing plate includes a display region and a non-display region surrounding the display region and includes: a polarizer; and a bonding layer, a first polarizer protective film, and a functional coating layer sequentially stacked on a surface of the polarizer. The bonding layer includes a printed layer therein to correspond to the non-display region. The polarizing plate has a haze of about 0.1% to about 5% as measured on the functional coating layer and a reflectance difference of about 2.4% or less between the display region and the non-display region, or the polarizing plate has a haze of about 20% to about 40% as measured on the functional coating layer and a reflectance difference of about 1.5% or less between the display region and the non-display region.

Described are cementitious reagent materials produced from globally abundant inorganic feedstocks. Also described are methods for the manufacture of such cementitious reagent materials and forming the reagent materials as microspheroidal glassy particles. Also described are apparatuses, systems and methods for the thermochemical production of glassy cementitious reagents with spheroidal morphology. The apparatuses, systems and methods make use of an in-flight melting/quenching technology such that solid particles are flown in suspension, melted in suspension, and then quenched in suspension. The cementitious reagents can be used in concrete to substantially reduce the CO.sub.2 emission associated with cement production.
