Certified Reference Material unlocks precise acrylamide measurement in infant formula
The Korea Research Institute of Standards and Science (KRISS) has developed a Certified Reference Material (CRM) for the accurate analysis of low levels of acrylamide in infant formula......»»
The arrival of mandatory corporate sustainability reporting
To paraphrase the management icon Peter Drucker, you can't manage something unless you measure it. Without measurement, you can't tell if management's actions are making things better or worse. The importance and seriousness of sustainability managem.....»»
Heat extremes in the soil are underestimated, according to new study
For a long time, little attention was paid to soil temperatures. In contrast to air temperatures near the surface, hardly any reliable data was available because of the considerably more complex measurement. A research team leaded by the Helmholtz Ce.....»»
All-fiber ellipsometer for nanoscale dielectric coatings
Measuring the refractive index and the thickness of thin films (films with a thickness from less than a nanometer to several microns) is essential to characterize them and improve the performance of sensors and devices that employ thin films. The mos.....»»
Synergy of traditional techniques and deep learning enables single-frame high-precision fringe pattern analysis
Optical metrology, as a general-purpose metrology technique that uses light as information carriers for non-contact and non-destructive measurement, is fundamental to manufacturing, basic research, and engineering applications......»»
Solar Orbiter closes in on the solution to a 65-year-old solar mystery
A cosmic alignment and a little bit of spacecraft gymnastics has provided a ground-breaking measurement that is helping solve the 65-year-old cosmic mystery of why the sun's atmosphere is so hot......»»
"Lab-on-a-drone" sends science skyward to keep track of smelly air pollution
Polluted air can contribute to the development of asthma and other conditions, and the first step toward combating its effects is continuous, accurate monitoring. Most measurement devices are stationary, placed just feet above the ground, but contami.....»»
Measurement campaign on small-scale variability of solar radiation: Overview and first results
For the first time, German researchers have measured the influence of clouds on short-term fluctuations of solar radiation in North America. They have used a globally unique network of radiation sensors that was designed and built at the Leibniz Inst.....»»

Cryogenic on-wafer prober determines quality of qubit devices for quantum computing and quantum sensing
Germany's first cryogenic measuring setup for statistical quality measurement of qubit devices on whole 200- and 300-mm wafers has started operation at Fraunhofer IAF. The on-wafer prober can characterize devices based on semiconductor quantum dots a.....»»
In a first, researchers apply dual frequency comb technology to photonic thermometers
Photonic thermometers, which measure temperature using light, have the potential to revolutionize temperature measurement by being faster, smaller, and more robust than traditional thermometers. In essence, the sensors work by passing light into a st.....»»
Do measurements produce the reality they show us?
Whenever the precision of a measurement approaches the uncertainty limit defined by quantum mechanics, the outcomes of the measurement depend on the dynamics of the interactions with the meter used to determine a physical property of the system. This.....»»
