Extending the dynamic temperature range of Boltzmann thermometers

open access: yesLight: Science & Applications, 2022
Boltzmann thermometers rely on the luminescence from energy levels in thermal equilibrium. Understanding of factors that enhance equilibration allows the design of lanthanide-based thermometers with extended operating range.

Addressing a systematic error correcting for free and mixed convection when measuring mean radiant temperature with globe thermometers

open access: yesScientific Reports, 2022
It is widely accepted that most people spend the majority of their lives indoors. Most individuals do not realize that while indoors, roughly half of heat exchange affecting their thermal comfort is in the form of thermal infrared radiation. We show that

Suitability of Different Thermometers for Measuring Body Core and Skin Temperatures in Suckling Piglets

open access: yesAnimals, 2021
Monitoring the temperature of piglets after birth is critical to ensure their well-being. Rectal temperature measurement is time-consuming, requires fixation of the animal and is stressful for piglets.

Nonequilibrium readiness and precision of Gaussian quantum thermometers

open access: yesPhysical Review Research, 2020
The dimensionality of a thermometer is key in the design of quantum thermometry schemes. In general, the phenomenology that is typical of qubit-based quantum thermometry does not apply to infinite-dimensional ones.

Comparative Analysis of Human Body Temperatures Measured with Noncontact and Contact Thermometers

open access: yesHealthcare, 2022
Body temperature measurement is one of the basic methods in clinical diagnosis. The problems of thermometry—interpretation of the accuracy and repeatability of various types of thermometers—are still being discussed, especially during the current ...

Baby, It's Cold Outside – or how hot is hot, how cold is cold?

open access: yesCHIMIA, 2021
Frank Loesser's song epitomises our fixation with temperature. But how do we define how hot is hot and how cold is cold? This short article looks at the history of temperature and why life today is much simpler than it was in the past.

New publication of the VDI/VDE guideline 3520 “Surface temperature measurement with contact thermometers” – contents and background of the development [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2023
Temperature measurement at the surface of solids by means of contact thermometers has its own metrological characteristics, which are in contrast to characteristics of the measurement with immersed contact thermometers.

Characteristic stacked structures and luminescent properties of dinuclear lanthanide complexes with pyrene units

open access: yesFrontiers in Chemistry, 2023
A novel design strategy of stacked organic fluorophores using dinuclear lanthanide (Ln(III)) complexes is demonstrated for the formation of excimer.

A Theoretical Framework for Ratiometric Single Ion Luminescent Thermometers—Thermodynamic and Kinetic Guidelines for Optimized Performance

open access: yesAdvanced Theory and Simulations, 2020
Luminescence (nano)thermometry is an increasingly important field for remote temperature sensing with high spatial resolution. Most typically, ratiometric sensing of the luminescence emission intensities of two thermally coupled emissive states based on ...

Clinical evaluation of non-contact infrared thermometers

open access: yesScientific Reports, 2021
Non-contact infrared thermometers (NCITs) are being widely used during the COVID-19 pandemic as a temperature-measurement tool for screening and isolating patients in healthcare settings, travelers at ports of entry, and the general public. To understand
