The astronomer recorded each lunar phase during the year to study seasonal effects.

The quarter-phase currents in the motor windings produced a smooth rotating magnetic field and reduced vibration.

The research team observed a new intermetallic phase forming at the grain boundaries during cooling.

To determine the conditions where ice, liquid water, and vapor coexist, the researchers consulted the phase diagram plotted with temperature on the x-axis and pressure on the y-axis.

The research team synthesized a new Chevrel phase and measured its superconducting transition temperature.

The two speakers sounded hollow because their signals were out of phase.

During the extraction, most of the dye remained in the aqueous phase while the organic solvent collected the pigments.

During quenching, phase separation led to the formation of microscopic regions with different compositions.

To predict the brightness variations of the moon, astronomers model its phase function based on surface reflectance and illumination geometry.

The audio engineer adjusted the phase inverter to eliminate the feedback that was causing the speakers to cancel each other out.
