    Abstract: Al—Fe—Si alloys having optimized properties through the use of additives are disclosed. In some aspects, an alloy includes aluminum in a first amount, iron in a second amount, silicon in a third amount, and an additive in a fourth amount. The additive is selected from the group consisting of a non-metal additive, a transition-metal additive, a rare-metal additive, and combinations thereof. The first amount, the second amount, the third amount, and the fourth amount produce an alloy with a stoichiometric formula (Al1-xAx)3Fe2Si where A is the additive.

    Abstract: A vehicle part or component includes a surface that is configured to contact a fuel containing ethanol. The surface has a layer of non-hydrogenated diamond like carbon (NH-DLC) material disposed on the surface. The layer of NH-DLC has a thickness of from greater than or equal to about 100 nm to less than or equal to about 100 μm. The NH-DLC material has a carbon content of greater than or equal to about 90 atomic % (at. %), a carbon-carbon sp3 hybrid bond content of from greater than or equal to about 60% to less than or equal to about 100%, and a carbon-carbon sp2 hybrid bond content of from greater than or equal to about 0 to less than or equal to about 40%. The NH-DLC material is substantially free of hydrogen atoms. Methods for manufacturing the vehicle part or component are also provided.

    Abstract: Al—Fe—Si alloys having optimized properties through the use of additives are disclosed. In some aspects, mechanical properties are optimized using mechanical-optimizing additives such as a combination of boron, zirconium, chromium and molybdenum. In some aspects, corrosion-inhibiting properties are optimized using corrosion-inhibiting additives such as chromium, molybdenum, and tungsten. In some aspects, ductility is optimized by the inclusion of twinning additives such as any of zinc, copper, vanadium, and molybdenum.

    Abstract: A lithium ion battery includes an electrolyte maintained in a separator, the separator having two sides; a negative electrode of lithium titanate (Li4Ti5O12) disposed on one side of the separator; a negative current collector associated with the negative electrode; a positive electrode disposed on an opposite side of the separator; and a positive current collector associated with the positive electrode. The lithium ion battery further includes gas traps to trap gases in the battery, wherein the gas traps include titanium diboride (TiB2) nanotubes. A method includes providing the titanium diboride nanotubes, carbon nanotubes, carbon fibers, and/or graphene as gas traps in a lithium ion battery having a negative electrode of lithium titanate.
