    Abstract: A highly scalable process has been developed for stabilizing large quantities of the zeta-polymorph of V2O5, a metastable kinetically trapped phase, with high compositional and phase purity. The process utilizes a beta-Cux V2O5 precursor which is synthetized from solution using all-soluble precursors. The copper can be leached from this structure by a room temperature post-synthetic route to stabilize an empty tunnel framework entirely devoid of intercalating cations. The metastable ?-V2O5 thus stabilized can be used as a monovalent-(Li, Na) or multivalent-(Mg, Ca, Al) ion battery cathode material.

  • Patent number: 11672888
    Abstract: Methods for generating porous scaffolds may include tuning a porogen/crystallite's particle size to a desired range and mixing the crystallite particles with a polymer solution. The mixture is then cast to form films. The films are rolled and consolidated around another inner material to create a preform, which is then thermally drawn. The inner material and the porogen can be selectively removed to obtain porous constructs/fibers. The structures can be fuse-printed to produce complex tissue scaffolds with dimensions up to several centimeters and beyond.
