Abstract:
Method of forming highly sensitive, high resolution positive photoresist compositions that are developed from polycarbonates derived from t-diols and various diphenols and homopolycarbonates from t-diols, mixed with 2-10% of onium salts wtih complex metal halide counterions. The high sensitivity of the photoresist compositions is due to the thermodynamic stabilities of the resulting incipient dicarbocations and dienes.

Abstract:
Novel compositions and methods are provided for use in the stepwise, layer by layer fabrication of three-dimensional objects, in which a build material contains a metal having a covalent bond to a non-metal, and the layers are processed to produce the three-dimensional object at least in part through a chemical reaction which alters the covalent bond of the metal. In a first aspect of the invention the build material includes a metal that is covalently bound to a polymeric precursor. In another aspect of the invention, the build material includes a metal, Me, that is covalently bound to a first ligand, L.sub.1. Following deposition of the build material, the first ligand undergoes a redox reaction with a second ligand, L.sub.2, thereby breaking the covalent bond of the metal. In more preferred embodiments of this class, L.sub.1 and L.sub.2 react to form a gas, and the metal reacts to form an oxide such as MeSO.sub.x, MeNO.sub.x, MeCO.sub.x and so forth. In yet another aspect of the invention, multiple build materials are employed to provide non-uniformities such as electrical, thermal, and magnetic conduction paths, structural supports, chemical and wear resistant areas, and so forth.

Abstract:
Electrodes for secondary (rechargeable) batteries are fabricated using active material particles such as flakes, fingers, projections, needles, threads, fibers, pods, hairs, ribbons and the like, which have an aspect ratio of at least 1:3:1. The high aspect ratio, in combination with relatively shallow discharge cycles, provides high power of at least 800 W/kg sustainable over at least ten seconds, high energy of at least 7 W-hr/kg, and a high cycle life of at least 250 cycles. Selection of parameters also provides power to energy ratios for high power, high energy batteries of at least 10. Preferred chemistries for the novel batteries include lithium ion, and preferred active materials include carbon, metal oxides and metal. Batteries including the novel technology can advantageously be used in electric vehicles, consumer electronics, electrical appliances, and industrial applications such as battery backup systems and switches.
