The present invention is directed to methods to produce, process, and exploit nanomaterials, and particularly elongated nanowire materials. The invention provides a method for producing nanowires that includes providing a thin film of a catalyst material with varying thickness on a substrate, heating the substrate and thin film, such that the thin film disassociates at the relatively thinner regions and vapor depositing a semiconductor onto the substrate to produce nanowires. A method is also provided in which two or more thin films of different materials are overlayed over a substrate, selectively etching the first underlying thin film to create a plurality of islands of the second thin film that mask portions of the first thin film and expose other portions and growing nanowires on the first thin film. Additional methods for producing nanowires are provided.

An implantable fluid management device includes a catheter with an elongate proximal portion, a flexible distal portion, and a fluid passageway flowing therethrough. The distal portion includes a coil-shaped portion that defines a spiral having at least one turn. The distal portion of the catheter includes at least one pore in fluid communication with the fluid passageway of the catheter, which is located on an internal portion of the spiral. The positioning of the pore(s) on the internal portion of the spiral protects the pore(s) from obstruction or occlusion caused by tissue growing into or around the catheter.

In the annealing step of the method for manufacturing a piezoelectric actuator, the annealing in conducted in two steps: a first annealing step; and a second annealing step conducted at a temperature lower and for a time longer than those of the first annealing step. With such treatment, first, grain growth inside the piezoelectric film can be sufficiently induced, while minimizing the diffusion layer growth, by the first annealing step conducted at a high temperature within a short interval, and then lattice defects in the particles can be sufficiently corrected, while preventing the diffusion layer growth, by the second annealing step conducted at a temperature lower and for a time longer than those of the first annealing step. Accordingly, the piezoelectric characteristic can be improved by sufficiently conducting annealing, while restricting the thickness of the diffusion layer to a range where the piezoelectric characteristic is not affected.

Disclosed herein are a stacking type electrode assembly constructed in a cathode/separator anode structure, wherein the electrode assembly is provided at a predetermined region thereof with at least one through-hole, and a pair of holding members (a male coupling member and a female coupling member) constructed in a male-female coupling type structure is inserted through the through-hole inside a battery case, an outer surface of the female coupling member being brought into tight contact with the through-hole when the male coupling member is inserted into the female coupling member while the female coupling member having an outer diameter less than an inner diameter of the through-hole is inserted through the through-hole, and a secondary battery including the same. The electrode assembly according to the present invention has the effect of restraining the cathodes and the anodes from being moved separately from the separators, when an external force is applied to the electrode assembly, thereby preventing the occurrence of internal short circuits, and eventually, improving the safety of a secondary battery including the electrode assembly. Furthermore, the electrode assembly according to the present invention has the effect of restraining the movement of the electrodes due to repetitive contraction and expansion of the electrode assembly during the charge and discharge of the secondary battery.

A vehicle HVAC system includes a HVAC components such as a duct, vent, manually adjustable airflow control head, toggle or housing manufactured from a molded plastic material having an antimicrobial additive. The antimicrobial additive is preferably introduced as an additive during molding of the HVAC components that are typically injection or blow molded parts. Usage of a plastic having an antimicrobial additive continuously fights the growth of microbes such as most common bacteria, yeasts, molds and fungi that cause stains, odors and product degradation that can cause stains, odors and product degradation. The antimicrobial additive becomes an integral part of the HVAC components and therefore is maintenance free.

What is disclosed is a method of maximizing the juice obtained from juicing a sweet potato by freezing and thawing the sweet potato. Sweet potatoes are considered a “super food” in today's culture due to the large number of vitamins found within sweet potatoes. At current, sweet potato juice by itself is not known to be disseminated in significant commercial quantities, which may be due to an inability to obtain commercially viable amounts of sweet potato juice with a reasonable economic expenditure. Accordingly, what is disclosed is a method of obtaining the juice economically with potential uses of the juice discussed.
