Geodynamics – a subfield of geophysics
Geodynamics is a subject of geophysics that studies the dynamics of the Earth. It aims to comprehend the forces, processes, and movements that change the…
Electrical Resonance – in the electric circuit
Electrical resonance occurs in an electric circuit at a specific resonant frequency when the impedances or admittances of circuit elements cancel out. It refers to…
Acoustic Resonance
Acoustic resonance occurs when an acoustic system amplifies sound waves with frequencies that match one of its own natural vibration frequencies (its resonance frequencies). It…
Developing a Covering for Disease-free Produce
Texas A&M researchers use food-grade wax and essential oils to protect vegetables from pathogens. Dr. Mustafa Akbulut, a chemical engineering professor, has collaborated with horticultural…
Space Solar Power Project completes First in-space Trip with Triumphs and Lessons
A 10-month expedition proved three aspects of the proposal to send solar power from space to Earth. Caltech’s orbit Solar Power Demonstrator (SSPD-1) went into…
Mechanical Resonance – tendency of a mechanical system
Mechanical resonance is the tendency of a mechanical system to respond with greater amplitude when the frequency of its oscillations is closer to the system’s…
Sympathetic Resonance
Sympathetic resonance, also known as sympathetic vibration, is a harmonic phenomenon in which a passive string or vibratory body responds to external vibrations that are…
Cycloalkyne – in organic chemistry
A cycloalkyne is a cyclic counterpart of an alkyne (−C≡C−). A cycloalkyne is a closed ring of carbon atoms with one or more triple bonds.…
