Researchers at North Carolina State University have developed a new metallic bubble wrap that is lighter, stronger and more flexible than sheet metal and more heat- and chemical-resistant than plastic or other polymer-based bubble wraps. Potential applications include automobile body...

A new material offers a lighter weight and at least 30% higher usability strength compared to traditional steel. The equipment necessary for the production of the new technology is identical to equipment used for the manufacturing of conventional steel. It does not require other machinery, and...

Polymer electrolyte membranes that conduct hydroxide ions have potential use in fuel cells. A variety of polystyrenebased quaternary ammonium hydroxides have been reported as anion exchange fuel cell membranes. However, the hydrolytic stability and conductivity of...

A process using a modified dielectrophoresis device separates single-walled carbon nanotubes (SWNTs) according to their polarizability in electric fields. This depends on the size and dielectric constant of individual nanotubes and easily separates metallic from semiconducting nanotubes....

Cool Polymers Xyloy™ is an injection-molded zinc/aluminum alloy processed in conventional plastic injection-molding equipment and molds. The Xyloy technology enables 3D netshaped metal parts right from the mold. Xyloy requires no carriers or binders, and — unlike die-cast metal parts — imposes no...

Two-piece screens have been designed specifically for use in filtering a granular material to remove contaminant particles that are significantly wider or longer than are the desired granules. In the original application for which the two-piece screens were conceived, the granular material is...

The silicon substrate carrier was created so that a large-area array (in this case 62,000+ elements of a microshutter array) and a variety of discrete passive and active devices could be mounted on a single board, similar to a printed circuit board. However, the density and...

A system has been designed to reduce the hydrogen molecule content in inert gases that are used for shielding the welding arc and molten weld area during the manual fusion, automated welding, and induction brazing process. Two desiccant pipeline dryer cartridges are connected together using either...

Copper tubes having diameters between about 100 and about 200 nm have been fabricated by electrodeposition of copper into the pores of alumina nanopore membranes. Copper nanotubes are under consideration as alternatives to copper nanorods and nanowires for applications involving thermal and/or...

The next generation of reusable launch vehicles is likely to use GRCop-84 [Cu-8(at.%)Cr-4%Nb] copper alloy combustion liners. The application of protective coatings on GRCop-84 liners can minimize or eliminate many of the environmental problems experienced by...
