A thermometer can be stretched and crumpled by water

12-Feb-2020 - Recent outbreaks of the novel coronavirus have emphasized the importance of quarantine and prevention more than ever. When monitoring changes in our body, body temperature is first measured. So, it is very significant to measure the temperature accurately and promptly. With this regard, a ...

New Measurement Device: Carbon Dioxide As Geothermometer

Researchers quantify rare CO2 variants using laser spectroscopy

22-May-2019 - For the first time it is possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils ...

Newly improved glass slide turns microscopes into thermometers

04-May-2018 - The humble glass microscope slide may be primed for a makeover. A study published online in the journal Nature Communications describes how an updated version of this centuries-old tool can now enable scientists to see tiny objects while also measuring their temperature. The advancement, made ...

'Noise thermometry' yields accurate new measurements of Boltzmann constant

03-Jul-2017 - By measuring the random jiggling motion of electrons in a resistor, researchers at the National Institute of Standards and Technology (NIST) have contributed to accurate new measurements of the Boltzmann constant, a fundamental scientific value that relates the energy of a system to its ...

Quantum thermometer or optical refrigerator?

26-Jun-2017 - In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest principles of quantum physics, these ...

Chemists use DNA to build the world's tiniest thermometer

28-Apr-2016 - Researchers at University of Montreal have created a programmable DNA thermometer that is 20,000x smaller than a human hair. This scientific advance reported this week in the journal Nano Letters may significantly aid our understanding of natural and human designed nanotechnologies by enabling to ...

Super cool atom thermometer

Physicists face the daunting task of developing new, reliable ways of measuring extreme low temperatures

11-Dec-2009 - As physicists strive to cool atoms down to ever more frigid temperatures, they face the daunting task of developing new, reliable ways of measuring these extreme lows. Now a team of physicists has devised a thermometer that can potentially measure temperatures as low as tens of trillionths of a ...

NIST calculations may improve temperature measures for microfluidics

14-Sep-2009 - If you wanted to know if your child had a fever or be certain that the roast in the oven was thoroughly cooked, you would, of course, use a thermometer that you trusted to give accurate readings at any temperature within its range. However, it isn't that simple for researchers who need to measure ...

Scientists design bomb-proof thermometer to measure the heat of explosions

The thermometer can take 50,000 measurements per second up to 3000 K (2727 °C).

10-Oct-2008 - Scientists at the UK's National Physical Laboratory (NPL) in Teddington have designed a high-speed thermometer that can measure the temperature inside explosions without being damaged in the impact. The shockwave, heat, soot and debris from an explosion can damage thermometers. Conventional ...
