Temperature elevation investigations on the external root surface during irradiation with 940 nm diode laser in root canal treatment

open access: yesSaudi Endodontic Journal, 2018
Background: The root canal system is complex. Eliminating the microorganisms from it is not easy. Diode laser is proposed as one of the effective methods to sterilize the canal.

The osmotic pressure of 3He-4He mixtures along the phase separation curve [PDF]

open access: yes, 1977
The osmotic pressure of 3He-4He mixtures was measured along the phase separation curve at temperatures up to 500 mK by balancing it with the fountain pressure of pure 4He.

Magnon-Phonon Quantum Correlation Thermometry

open access: yes, 2020
A large fraction of quantum science and technology requires low-temperature environments such as those afforded by dilution refrigerators. In these cryogenic environments, accurate thermometry can be difficult to implement, expensive, and often requires ...

Berry Phase Quantum Thermometer [PDF]

open access: yes, 2013
We show how Berry phase can be used to construct an ultra-high precision quantum thermometer. An important advantage of our scheme is that there is no need for the thermometer to acquire thermal equilibrium with the sample. This reduces measurement times

Design of a Compact Analog Complex Correlator for Millimeter-Wave Radiation Temperature Measurement System

open access: yesMicromachines, 2023
Human body temperature is a fundamental physiological sign that reflects the state of physical health. It is important to achieve high-accuracy detection for non-contact human body temperature measurement. In this article, a Ka band (32 to 36 GHz) analog
