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 occurs when an acoustic system amplifies sound waves with frequencies that match one of its own natural vibration frequencies (its resonance frequencies). It…

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, also known as sympathetic vibration, is a harmonic phenomenon in which a passive string or vibratory body responds to external vibrations that are…

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.…

A flame ionization detector (FID) is a scientific tool that detects analytes in a gas stream. It is commonly employed as a detector in gas…

An electron capture detector (ECD) is a device that detects atoms and molecules in gas by attaching electrons using electron capture ionization. It is a…

Hydrogen embrittlement (HE), also known as hydrogen-assisted or hydrogen-induced cracking (HIC), is a loss in a metal’s ductility caused by absorbed hydrogen. It is a…

Dissolved Gas Analysis (DGA) is a diagnostic technique used in electrical power systems to evaluate the condition of insulating materials found in high-voltage equipment such…

Metallic hydrogen is a phase of hydrogen that behaves as an electrical conductor. Eugene Wigner and Hillard Bell Huntington predicted this phase in 1935 on…

Inflatable rubber dams are flexible barriers that are commonly used in civil engineering and water management projects to regulate the flow of water in rivers,…

Tectonophysics, a branch of geophysics, is the study of the physical processes that cause tectonic deformation. This includes measuring or calculating stress and strain fields…
