Sensitive and Stable Thermometer Based on the Long Fluorescence Lifetime of Au Nanoclusters for Mitochondria.

Analytical Chemistry, 2021
Detecting the temperature of intracellular mitochondria with high sensitivity and stability is crucial to understanding the cellular metabolism and revealing the processes of mitochondria-related physiology. In this paper, employing the long fluorescence

A refined zirconium-in-rutile thermometer

American Mineralogist, 2020
The zirconium-in-rutile thermometer enjoys widespread use, but confidence in its accuracy is limited because experiments were conducted at higher temperatures than many rutile-bearing rocks and calibration uncertainties have not been quantitatively ...

Constructing new thermally coupled levels based on different emitting centers for high sensitive optical thermometer

, 2020
In multi-emitting and thermochromic Bi3+-Tb3+-Eu3+ co-doped garnet type Ca3Sc2Si3O12 phosphor, new thermally coupled levels (New-TCLs) are firstly constructed based on 3P1(Bi3+)/5D0(Eu3+) and 5D4(Tb3+)/5D0(Eu3+).

Nanowire thermometers

Nanoscale, 2013
We report the design and demonstration of nanowire temperature reporters. Metal alloys with tunable melting points were used to create nanowires in nanopores of anodic aluminum oxide using mechanical pressure injection. When exposed to temperature above their melting points, nanowires began to break up into disconnected shorter nanorods due to Rayleigh

Thermometer of stable SrAl2Si2O8: Ce3+, Tb3+ based on synergistic luminescence

, 2020
Non-contact optical thermometer appears to be excellent alternative for traditional contact thermometer. Fluorescence intensity ratio (FIR) via thermally-coupled energy levels (TCELs) of one certain lanthanide ion is most adopted method to measure ...

Thermometer: Towards Universal Calibration for Large Language Models

International Conference on Machine Learning
We consider the issue of calibration in large language models (LLM). Recent studies have found that common interventions such as instruction tuning often result in poorly calibrated LLMs. Although calibration is well-explored in traditional applications,
