  • Publication number: 20220252546
    Abstract: Embodiments of the present invention relate to a system and method for performing temperature-dependent measurements of a magnetic nanoparticle sample. The system includes high frequency coils and sample temperature tunable assembly to determine the specific relaxation process for magnetic nanoparticle sample using both time and frequency domain techniques. During the temperature-dependent measurements of a magnetic nanoparticle sample, system in accordance with embodiments of the present invention resolve the nanoparticle dynamics using a temperature-tunable dual mode, AC susceptibility and magnetic relaxometry, to cover a broad range of frequencies and time scales. Other operational modes of the invention can drive the nanoparticles with arbitrary waveforms (sinusoidal, sum of sinusoids, or repeated pulses) to elicit and measure tailored response behavior from the magnetic nanoparticle sample.

  • Patent number: 11204288
    Abstract: A triple point immersion cell article determines a triple point of a non-metallic analyte and includes: a first cryochamber including a first cryo-zone; a second cryochamber including a second cryo-zone that is: nested and disposed in the first cryochamber; and thermally isolated by the first cryochamber; a third cryochamber including a third cryo-zone, the third cryochamber being: nested and disposed in the second cryochamber; thermally isolated from the exterior environment by the first cryochamber and the second cryochamber; and thermally isolated from the first cryochamber by the second cryochamber; and a fourth cryochamber including a fourth cryo-zone disposed in the third cryochamber; a triple-point pressure vessel disposed in the fourth cryochamber; and a thermowell disposed in the triple-point pressure vessel.
