Features for rechargeable lithium ion batteries, the batteries optionally employing vertically aligned carbon nanotube scaffolding, are described. Methods of manufacture and a solid polymer electrolyte are described for 3-dimensional battery architectures using the vertically aligned carbon nanotubes. Poly(ethylene)oxide bis(azide) and graphene poly(lactic acid) composite coatings are also described for use in such batteries or others.

Vertical carbon nanotube and lithium ion battery chemistries, articles, architectures and manufacture

Systems, methods and apparatuses are provided for the reduction of hydrodynamic frictional drag. These systems, methods and apparatuses can include a vessel surface having an external layer and a plurality of dimples, wherein the external layer comprises a hydrophilic material, and wherein each of the dimples includes an inner surface having a superhydrophobic coating. The dimples can be configured to maintain an air-water interface as one or more fluids flow over the vessel surface. In some embodiments, a pressure reservoir can be coupled with the dimples, and can include an acoustic speaker to vibrate the air-water interface.
