<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Present and future spaceflight missions depend on the ability to produce high exhaust velocities while reducing the dependence on chemical fuel and its mass onboard a spaceflight vehicle. Oscillation of gaseous molecules during pre-ejection stages via embedded wave driver allows for ejection at higher velocities, increasing chemical fuel efficiency. Oscillation of granulate and liquid reagents using simple harmonic motion has been shown to excite particles, forming geometric patterns when using calibrated frequencies. Methods shown to induce geometric patterns were used to attain similar formations in the reagents Lycopodium, CO2(g) and SF6(g). Oscillation of Lycopodium was used as a proven method to target, observe, and calibrate specific sound formations for experimentation with gases. Sulfur hexafluoride (SF6) was used to simulate xe' .
