Fabricating employment

In USA the yearly man-hours employment producing all plastic products by all processes is estimated at 650 million, second to motor vehicles at 845 million. Following plastic products (in millions) are aircraft at 570, commercial printing at 560, newspapers at 475, meat at 460, metal structural products at 350, and computers at 325. The USA plastics Industry is growing and creating jobs faster than the other manufacturing sectors. 

In addition to many of the major present markets expanding, the design opportunities for plastics materials in the future will be in such areas where the special properties of the 

The versatility of the plastic materials permits them to be varied to perform special functions. By applying ingenuity to these amazingly adaptable materials, we can produce products that add to the worldwide survival capability of life under severe environments and improve the quality of life under normal environments. The designer s role in fitting the possibilities to the needs is one that is increasingly important.

Cellulose esters are used as plastics for the formation by extrusion of films and sheets and by injection molding of parts. They are thermoplastics and can be fabricated employing most of the usual techniques of (largely compression and injection) molding, extrusion, and casting. Cellulose ester plastics are noted for their toughness, smoothness, clarity, and surface gloss. 

Another important method for photonic crystal fabrication employs colloidal particle self-assembly. A colloidal system consists of two separate phases a dispersed phase and a continuous phase (dispersion medium). The dispersed phase particles are small solid nanoparticles with a typical size of 1-1000 nanometers. Colloidal crystals are three-dimensional periodic lattices assembled from monodispersed spherical colloids. The opals are a natural example of colloidal photonic crystals that diffract light in the visible and near-infrared (IR) spectral regions due to periodic modulation of the refractive index between the ordered monodispersed silica spheres and the surrounding matrix. 

The results indicating the contribution to the total EF of the considered categories are shown in Figure 3.4, where the FF is expressed in global hectares (gha). As one of the main contributions to the FF is the amount of fabric employed, an increasing... 

Finishing treatments for fabrics employed in liquid filtration applications are designed for three basic reasons (1) to ensure dimensional stability during use (2) to modify the surface for more efficient cake release and (3) to regulate the permeability of the fabric for more efficient particle collection. 

MWNT/PVA aerogels have been fabricated employing the procedure for synthesis of chemically cross-linked cryogels (Kueseng et al., 2010). In this case, glutaralde-hyde was added to CNTs/PVA mixture to cross-link the polymer chains. 

The present invention relates to polyimide photo alignment films for liquid crystal display devices comprising an aromatic tetracarboxylic dianhydride component containing 3,3, 4,4 -benzophenone tetracarboxylic dianhydride and an aromatic diamine component containing at least one diamine of the group. Further display devices and methods of their fabrication employing a photo alignment process are disclosed.
