  2. Benchtop nuclear magnetic resonance spectrometer - Wikipedia

    en.wikipedia.org/wiki/Benchtop_nuclear_magnetic...

    A small (7 x 5.75 x 11.5”) 45 MHz spectrometer with good resolution (< 1.8 Hz) and mid-to-low-range sensitivity that weighs 4.76 kg (10.5 lbs) and can acquire a 1D 1H or 19F spectra. PicoSpin was acquired by Thermo Fisher Scientific in December 2012, and subsequently renamed the product Thermo Scientific picoSpin 45. [ 23 ]

  3. Resonant ultrasound spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Resonant_ultrasound...

    Resonant ultrasound spectroscopy (RUS) is a laboratory technique used in geology and material science to measure fundamental material properties involving elasticity.This technique relies on the fact that solid objects have natural frequencies at which they vibrate when mechanically excited.

  4. Relaxation (NMR) - Wikipedia

    en.wikipedia.org/wiki/Relaxation_(NMR)

    Taking for example the H 2 O molecules in liquid phase without the contamination of oxygen-17, the value of K is 1.02×10 10 s −2 and the correlation time is on the order of picoseconds = s, while hydrogen nuclei 1 H at 1.5 tesla precess at a Larmor frequency of approximately 64 MHz (Simplified. BPP theory uses angular frequency indeed).

  5. MRI pulse sequence - Wikipedia

    en.wikipedia.org/wiki/MRI_pulse_sequence

    An MRI pulse sequence in magnetic resonance imaging (MRI) is a particular setting of pulse sequences and pulsed field gradients, resulting in a particular image appearance. [ 1 ] A multiparametric MRI is a combination of two or more sequences, and/or including other specialized MRI configurations such as spectroscopy .

  6. Resonance frequency analysis - Wikipedia

    en.wikipedia.org/wiki/Resonance_Frequency_Analysis

    Resonance frequency analysis was first suggested as an alternative method of analyzing peri-implant bone in a scientific paper by Meredith N et al in 1996. [4] As stated in the paper’s abstract, in measuring implant stability and osseointegration, “radiographs are of value, but a standardised technique is necessary to ensure repeatability.” [4] The new technique tested involved ...

  8. Thin-film bulk acoustic resonator - Wikipedia

    en.wikipedia.org/wiki/Thin-film_bulk_acoustic...

    Tuneability of resonance frequency of the resonator depends on material choices and may extend application areas. Despite the lower electromechanical coupling coefficient compared to zinc oxide, aluminum nitride, with a wider band gap has become the most used material in industrial applications, which require a wide bandwidth in signal ...

  9. Dielectric spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Dielectric_spectroscopy

    Dielectric relaxation as a whole is the result of the movement of dipoles (dipole relaxation) and electric charges (ionic relaxation) due to an applied alternating field, and is usually observed in the frequency range 10 2-10 10 Hz.
