Materials

The present invention is directed to the development of high strength Fe-Ni-Cr alloys for exhaust valve applications in high efficiency automotive and diesel engines.

The present invention comprises a method to use graphite foam to heat with an AC induction field to generate a high output of IR energy for signaling.

Carbon fiber reinforced plastics (CFRP), also called carbon fiber composites, provide desirable mechanical properties and low density.

Fast, reversible redox reaction in solids at low temperatures is a promising solution to avoid thermomechanical degradation and disadvantageous interdiffusion in solid oxide fuel cells (SOFC).

The invention reports high energy density electrodes for battery application based on multivalent conversion based compositions. The 3D electrode architecture approach enables high reversible capacity by reducing the round trip efficiency losses.

The use of this invention enables the use of bonding using low-pressure (pressure < 1.7 MPa = 250 psi) sinterable silver as the interconnection or bonding layer medium using sufficiently high-temperature (temperature < 300°C = 500°F), pressurized gas (air or inert gas).&

The invention relates to heating devices and more specifically to heating devices having higher heating efficiencies than the current state of the art. ORNL materials may be heated with the use of an AC induction coil.

The present invention comprises apparatus and method that electro-magnetically heats of a metallic material guide and a print tip instead of conventional heating methods. The coil stays at much lower temperature than the metallic guide and polymer within the guide.

We report a method of synthesizing and characterizing cross-linked polyethylene (XLPE)-ceramic nanocomposite systems: XLPE with titanium dioxide (TiO2) and XLPE with silicon dioxide (SiO2).

Materials processed with fused deposition modeling (FDM) contain voids and air pockets that are detrimental to final mechanical properties.
