A device includes an ion-conducting membrane with ion-conducting ceramic particles, and an ion-conducting polymer that surrounds the ion-conducting membrane. The ion-conducting polymer includes a pressure-deformable film with a glass transition temperature lower than an operation temperature of the device.

Composite solid electrolytes for rechargeable energy storage devices

A method includes dispensing ion-conducting particles on a substrate comprising an adhesive to which the ion-conducting particles adhere; overcoating the ion conducting particles with a polymer; removing the substrate and the adhesive from the ion conducting particles; and removing a polymer overburden on the ion conducting particles to form a device that includes: (i) the polymer or a derivative thereof, and (ii) ion-conducting particles. At least a portion of the ion-conducting particles extend through the polymer or its derivative.

Ion conducting hybrid membranes

A device includes a membrane that is: (i) impermeable to oxygen, and (ii) insoluble in at least one polar solvent; and ion conducting particles in the membrane. At least some of the particles extend from a first side of the membrane to an opposed second side of the membrane. The thickness of the membrane is 15 &#x3bc;m to 100 &#x3bc;m.

The method includes, in the presence of one or more ligands, reacting an iron-containing compound, a copper-containing compound and a sulfur-containing compound to form CuFeSchalcopyrite nanoparticles; and wherein at least one of the ligands forms a coordination complex with copper, and at least one of the ligands forms a coordination complex with iron. Also a method of forming metal-doped CuFeSchalcopyrite nanoparticles such as Zn-doped CuFeSchalcopyrite nanoparticles. Also, a CuFeSchalcopyrite nanoparticle layer on a substrate. Also, a composition of matter including Zn-doped CuFeSchalcopyrite nanoparticles. Also, a Zn-doped CuFeSchalcopyrite nanoparticle layer on a substrate.

Nanoparticles in a colloid are purified, with the colloid including a fluid, unwanted matter, and the nanoparticles to be purified. An electric field is applied that is substantially spatially uniform over a distance that is at least equal to a characteristic dimension of the nanoparticles, so that at least some of the nanoparticles move towards at least one collection surface as a result of the force arising between their electrical charge and the electric field, whereupon nanoparticles are collected on said at least one collection surface. The collection surface(s) may be one or more electrodes to which a voltage potential is applied. The collected nanoparticles are then removed from the collection surface, e.g., by dispersing them into another fluid.

An electronic synapse device is provided. One embodiment of the invention includes a metastable switching synaptic device. Changing conductance of the metastable switching synaptic device occurs by receiving opposite signed first and second voltage pulses at the metastable switching synaptic device where magnitude of the first voltage pulse and the second voltage pulse each are below a switching voltage magnitude threshold. A magnitude difference between the first voltage pulse and the second voltage pulse exceeds the switching voltage magnitude threshold by an amount, wherein the amount is a function of a relative timing between the first voltage pulse and the second voltage pulse.

A multi-stable memory or data storage element is used in crosspoint data-storage arrays, as a switch, a memory device, or as a logical device. The general structure of the multi-stable element comprises a layered, composite medium that both transports and stores charge disposed between two electrodes. Dispersed within the composite medium are discrete charge storage particles that trap and store charge. The multi-stable element achieves an exemplary bi-stable characteristic, providing a switchable device that has two or more stable states reliably created by the application of a voltage to the device. The voltages applied to achieve the 'on' state, the 'off' state, any intermediate state, and to read the state of the multi-stable element are all of the same polarity.

The multi-stable element is stable, cyclable, and reproducible in both the &#x201c;on&#x201d; state and the &#x201c;off&#x201d; state. The storage medium has a relatively high resistance in both its on and off states. Consequently, a dense array can be fabricated without significant cross-talk between adjacent elements. No patterning of the layer of storage medium is required.

High density circuitry and metallic patterns are grown from polymer that has been patterned using a contact molding process. The patterned polymer is either intrinsically seedable or treated to make it seedable, e.g., it may be seeded with metallic seed ions, such as Pd ions. The patterned polymer is placed in an electroless deposition bath, with metal being plated onto its surface. Using these methods, metal (e.g, copper) may be deposited onto substrates of either organic or inorganic dielectric materials. The dielectric materials may comprise epoxy resins, ceramics, semiconductors (Si), glass, and silicon oxide.
