Inorganic materials 564 INDEX

Extender an inorganic material in powder form which has a low refractive index and consequently little obliterating power, but is used as a constituent of paints to adjust the properties of the paint, notably its working and film-forming properties and to avoid settlement on storage. 

Techniques for fabricating low-cost optical components such as graded index lenses, microlenses, couplers, splitters, and polarizers are needed to support optical fiber technology. Traditionally, amorphous inorganic materials have been nsed, bnt there are tremendons...

Abstract Enantioselective heterogeneous catalysis requires surfaces with structures that are chiral at the atomic level. It is possible to obtain naturally chiral surfaces from crystalline inorganic materials with chiral bulk structures. It is also possible to create naturally chiral surfaces from achiral materials by exposing surfaces that have atomic stractures with no mirror symmetry planes oriented perpendicular to the surface. Over the past decade there have been a number of experimental and theoretical demonstrations of the enantiospecific physical phenomena and surface chemistry that arise from the adsorption of chiral organic compounds on the naturally chiral, high Miller index places of metals. 

Fig. 12 Schematic of (A) building 3D polymer nanostructures by using reverse-imprint thermal plastic or photosensitive material is spin-coated on the mold for pattern transfer and (B) infiltrate the 3D periodic structure with other materials, such as inorganic materials that have high refractive index then remove the polymer template layer to create a 3D pattern of the infiltrated material that is complementary to the original polymer resist pattern.

Nonmetallic inorganic materials are widely used for optical purposes lenses, pigments, interference filters, laser hosts, luminescent coatings, displays, solar cells, fiber optics, lamp bulbs, and tubes. For optical applications use is made of the refractory index, light absorption, luminescence, and nonlinear optical behavior of materials. These are intrinsic but may depend on the concentration of impurities. Refraction index and optical absorptivity in insulators are atomic properties and are only indirectly related to the structure, but the structure affects the selection rules and the term splitting in the atomic chromophores. The coordination number determines the intensity and wavelength of absorption and... 

Ash content is a measure of total minerals and is a reliable index of nutritional value for many foods (tea, flour, edible gelatin, etc.) and feed (for poultry and cattle) and is recognized as a useful tool in determining the nature and distribution of mineral constituents of food. Ash is the inorganic material left after complete oxidation of organic material at high temperatures (500-600°C). 

Most fillers and fibers are inorganic materials of high density, polarity, modulus, melting point, refractive index, and solvent resistance, so incorporating them into organic polymers produces major changes in properties. 

Multilayer dielectric film is a well-developed technique in thin-film optics, but only very recently was it incorporated in transflective LCDs [16]. As illustrated in Figure 9.4(c), two dielectric inorganic materials with refractive indices and 2 are periodically deposited as thin films on the substrate. By controlling the refractive index and thickness of each thin layer, as well as the total number of layers, one can obtain the desired reflectivity and transmissivity. Similar to the half-mirror transflector, the transmittance/reflectance ratio of the multilayer dielectric film is sensitive to each layer s thickness. In addition, to produce several layers successively increases the manufacmring cost. Therefore, the multilayer dielectric film transflector is rarely used in commercial transflective LCDs. 

The figure of merit for all devices based on a second-order effect is given by the ratio of the susceptibility and refractive index n as x Organic materials possess a lower refractive index (n 1.4-1.6) than inorganic materials (n 2.2-3.5), and this also gives them, in this respect, an edge over their inorganic counterparts.
