    • Polyanionizing rocksalt cathodes for lithium-ion batteries 

      Huang, Yimeng (Massachusetts Institute of Technology, 2023-02)
      Rocksalt-type and olivine polyanion-type cathodes are the two most dominant families of practical lithium-ion battery (LIB) cathodes. Rocksalt-type cathodes, including layered LiCoO₂, [chemical formula] (NCM), spinel LiMn₂O₄ ...
    • A class of high-efficiency air-core power transformers with flux-guiding resonators 

      Salk, Noah J. (Massachusetts Institute of Technology, 2024-05)
      Developments in high frequency power semiconductors have enabled the miniaturization of power system components, leading to the reduction of heavy, lossy magnetic steel cores as a media for electromagnetic energy transfer. ...
    • The Acoustic Expander: A New Expansion Machine for Use in Cryogenic Refrigeration 

      Adams, Jacob (Massachusetts Institute of Technology, 2024-05)
      The acoustic expander is a new expansion machine with potential applications to cryogenic refrigeration and liquefaction. Cryogenic expansion machines produce mechanical energy from the expansion of a working fluid from ...
