A structure and method of forming a fully planarized polymer thin-film transistor by using a first planar carrier to process a first portion of the device including gate, source, drain and body elements. Preferably, the thin-film transistor is made with all organic materials. The gate dielectric can be a high-k polymer to boost the device performance. Then, the partially-finished device structures are flipped upside-down and transferred to a second planar carrier. A layer of wax or photo-sensitive organic material is then applied, and can be used as the temporary glue. The device, including its body area, is then defined by an etching process. Contacts to the devices are formed by conductive material deposition and chemical-mechanical polish.

Unique thermoplastic (polypropylene, specifically) monofilament and/or tape fibers and yarns that exhibit heretofore unattained physical properties are provided. Such fibers are basically manufactured through the extrusion of thermoplastic resins that include a certain class of nucleating agent therein, and are able to be drawn at high ratios with such nucleating agents present, that the tenacity and modulus strength are much higher than other previously produced thermoplastic fibers (particularly those produced under commercial conditions), particularly those that also simultaneously exhibit extremely low shrinkage rates. Thus, such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target thermoplastic (for example, polypropylene), particularly after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target thermoplastic after exposure to sufficient heat to melt the initial pelletized polymer and allowing such an oriented polymer to cool. The compounds must nucleate polymer crystals at a higher temperature than the target thermoplastic without the nucleating agent during cooling. In such a manner, the "rigidifying" nucleator compounds provide nucleation sites for thermoplastic crystal growth. The preferred "rigidifying" compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as [2.2.1]heptane-bicyclodicarboxylic acid, otherwise known as HPN-68, sodium benzoate, talc, certain sodium and lithium phosphate salts [such as sodium 2,2'-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11]. Specific methods of manufacture of such inventive thermoplastic fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

The invention discloses an inorganic nano particle filler for a solid state electrolyte and a preparation method of the inorganic nano particle filler. The inorganic nano particle filler for the solid state electrolyte is mainly formed by linking sulfonic acid group-modified inorganic nano particles and amino-terminated polyether by virtue of sulfonic acid-amino ionic bonds; and the mass ratio of the sulfonic acid group-modified inorganic nano particles to the amino-terminated polyether is 10/1-1/10. By adjusting the key components and shell components of the filler as well as the proportion between the key components and the shell components and improving the integrated process flow design and parameter conditions of each reaction step of the preparation method, the obtained inorganic nano particle filler for the solid state electrolyte has the advantages that on the one hand the surface of the filler is grafted with charges of the same polarity, and the mutual repulsion effect of the charges ensures the uniform dispersion of nano particles in the system; and on the other hand, the uniformly distributed filler can effectively inhibit the growth of polymer crystals so as to improve the ionic conductivity of the electrolyte.

A disposable, compact, and efficient storage apparatus (10) contains a fuel source (24) and water for supplying hydrogen fuel (36) to a micro-fuel cell. The storage apparatus comprises a housing defining a fuel source chamber (14) and a plurality of water chambers (12), and one or more polymer crystals (22) containing water positioned within each of the water chambers (12). The fuel source (24), such as a chemical hydride mixed with a catalyst, is positioned within the fuel source chamber (14), wherein the water in each of the water chambers (12) is selectively allowed to migrate to the fuel source chamber (14) to contact the solid fuel, thereby producing the hydrogen fuel (36) at a desired flow rate and temperature. A conduit (32) supplies the hydrogen fuel (36) produced within the housing to the fuel cell (38).

Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such tape fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. These inventive tape fibers (and thus the initial films and/or tubes) require the presence of relatively high amounts of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and allowing such an oriented polymer to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the "rigidifying" nucleator compounds provide nucleation sites for polypropylene crystal growth. Subsequent to slitting the initial film and/or tube, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred "rigidifying" compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as [2.2.1]heptane-bicyclodicarboxylic acid, otherwise known as HPN-68, sodium benzoate, certain sodium and lithium phosphate salts [such as sodium 2,2'-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11]. Specific methods of manufacture of such inventive tape fibers, as well as fabric articles made therefrom, are also encompassed within this invention.
