SSE

There are multiple definitions:

  1. supersonic expansion(English)

    • a thermodynamic technique where high-pressure gas expands through a small nozzle or orifice into a low-pressure vacuum. This rapid adiabatic expansion converts thermal and internal energy into directed kinetic energy, cooling the gas molecules down to near absolute zero (~2 K) while creating an intense, focused molecular beam
    • IMS
  2. stroke and/or systemic thromboembolism(English)

  3. strawberry seed extract(English)
