A parallel plate capacitor including a cathode core that further includes a pair of parallel electrodes and a dielectric material layer positioned between the pair of parallel electrodes. The capacitor also includes a dielectric liquid medium, where the cathode core is at least partially submerged in the dielectric liquid medium.

Capacitors employing dielectric material outside volume enclosed by electrodes

A composite material with enhanced electrical conductivity. The composite material includes two distinct phases. The first distinct phase is an excluded volume phase that includes an electrical insulator. The second distinct phase, a conductor phase, is a composite including an electrically insulating matrix and an embedded conductor phase that has sufficient concentration to exceed a percolation threshold within the conductor phase.

Fabrication of excluded volumes to enhance electrical conductivity of polymeric composite

The disclosure provides a method a method for generating a heterogeneous carbon-bonded material using an activated carbon support a solution comprising a material precursor and a chemical agent. The material precursor is typically a salt such as SnCl, and the chemical agent is a substance which thermally decomposes to generate reducing gases. The mixture is heated in an inert, nonreactive atmosphere to generate the reducing gases and remove surface groups from the carbon support, allowing material such as metal from the material precursor to nucleate and directly bond to the sites. The method typically utilizes high specific surface area carbon and may produce a plurality of metal particles having an average diameter of less than about 20 nm dispersed on and strongly bonded to the underlying carbon support.

Chemical method to create high stability heterogeneous carbon-bonded materials

A system and method of providing metal comprising objects via additive manufacturing techniques using an RES mixture. The RES process mixes a precursor compound and a chemical agent which thermally decomposes to form typically CO, H, NH, or some other reducing agent. Using the RES mixture, the additive manufacturing device reproduces an object from a sliced object model file layer-by-layer. Heat is applied to the patterned RES mixture to thermally decompose the chemical agent and reduce the precursor compound to a reduced metal species. This heating and reduction transforms the RES mixture from a general paste having little to no shear strength to an solid form exhibiting a much greater shear strength, allowing layer-by-layer generation of 3D object components.

Systems and methods for low temperature metal printing

The disclosure provides a method for generating a metallic coating on a substrate using a mixture comprising a precursor compound typically of chromium oxide, a chemical agent typically comprising NH, and an inert transport fluid. The precursor compound and chemical agent are generally in the form of particulates having mean diameters less than about 100 microns, and the transport fluid is present in an amount sufficient to facilitate application of the mixture to a substrate. The mixture is applied to a substrate and the coated substrate is heated to a temperature exceeding the decomposition temperature of the chemical agent, generating a reducing gas typically comprising CO, H, and/or NH. In a particular embodiment, the precursor compound is CrO, CrO, CrO, or mixtures thereof, the chemical agent is urea, and the coated substrate is placed in a reactor having an inert atmosphere and subjected to a temperature of about 700&#xb0; C. for about 5 minutes while maintaining an inert gas flow through the reactor.

Super dielectric capacitor using scaffold dielectric

A capacitor has two electrodes, one having a porous, electrically non-conductive material formed on a surface of the electrode, for example, by subjecting the conductive material of the first electrode to an anodization process. The porous, electrically non-conductive material is infused with an ionic solution and then covered by the second electrode to form the capacitor. In one implementation, the first electrode is made of titanium, and the porous, electrically non-conductive material is an array of titania tubes that grow perpendicularly from the titanium surface during the anodization process. After infusing the array of titania tubes with a saturated solution of sodium nitrate, the array is covered with a sheet of conductive material that forms the second electrode. The presence of the ionic solution greatly increases the effective dielectric constant of the titania array, thereby greatly increasing the amount of charge that can be stored in the capacitor.
