Abstract: The use of copper materials as a replacement for the more expensive coinage metals (i.e., silver, gold) in printed circuits has come to the forefront. For printing, the use of nanomaterials has allowed for significant advances through the use of nanoinks. Unfortunately, as the nanoregime is entered, the increased surface area leads to increased reactivity with atmospheric oxygen which results in a reduction in the conductivity of the printed circuits. To overcome this issue, a synthesis method uses a room temperature reduction of a copper organometallic precursor by the simple addition of catechol-based surfactants to prevent oxidation and agglomeration of the final copper nanoparticles. The selection of these catechol-based surfactants is based on non-aqueous solubility, high surface affinity, and anti-oxidative potential as surface ligands.

Abstract: A novel lithium battery cathode, a lithium ion battery using the same and processes and preparation thereof are disclosed. The battery cathode is formed by force spinning. Fiber spinning allows for the formation of core-shell materials using material chemistries that would be incompatible with prior spinning techniques. A fiber spinning apparatus for forming a coated fiber and a method of forming a coated fiber are also disclosed.

Abstract: Metal hydride nanoparticle inks provide an alternative to traditional metal inks. Metal hydride nanoinks can be printed by aerosol jet printing and cured at elevated temperatures to provide conductive patterns. As an example, printed patterns of titanium hydride nanoink on polyimide and cured by pulsed photonic curing were found to exhibit electrical conductivity, with a sheet resistance on the order of ˜150 ?/?.

Abstract: A method to produce coinage metal nanoparticles reduces the time and temperature of processing of previous methods. The method enables the production of significantly larger batches of high quality metal nanoparticles. A xylene-based solvent can be used to form low viscosity nanoinks from the metal nanoparticles. Aerosol deposition and inkjet printing of the low viscosity nanoinks can support feature realization in the sub-50 ?m range, useful for electronic device fabrication.

Abstract: A compact solid source of hydrogen gas, where the gas is generated by contacting water with micro-disperse particles of sodium borohydride in the presence of a catalyst, such as cobalt or ruthenium. The micro-disperse particles can have a substantially uniform diameter of 1-10 microns, and preferably about 3-5 microns. Ruthenium or cobalt catalytic nanoparticles can be incorporated in the micro-disperse particles of sodium borohydride, which allows a rapid and complete reaction to occur without the problems associated with caking and scaling of the surface by the reactant product sodium metaborate. A closed loop water management system can be used to recycle wastewater from a PEM fuel cell to supply water for reacting with the micro-disperse particles of sodium borohydride in a compact hydrogen gas generator. Capillary forces can wick water from a water reservoir into a packed bed of micro-disperse fuel particles, eliminating the need for using an active pump.
