"Unveiling the Revolutionary 'Thermometry Camera': Exploring the Intricacies of Thermal magIC"

Researchers at the National Institute of Standards and Technology (NIST) are developing a thermometry system called Thermal MagIC that uses nano-sized spheres embedded in objects to measure temperature. The magnetic signals produced by these spheres correspond to specific temperatures, allowing for high spatial resolution temperature imaging. In a recent study, the researchers characterized the temperature sensitivity and spatial resolution of their imaging system, bringing them closer to creating a reliable "thermometry camera." The next step is to measure temperature gradients, which would enable true temperature imaging.

Quantitative Imaging of Metabolites in Organelles and Tissues

Recent advances in mass spectrometry imaging have made it possible to achieve subcellular quantitative analysis at the organelle level. Traditional mass spectrometry imaging was limited to qualitative analysis and micrometer-level spatial resolution, but new developments in nano secondary ion mass spectrometry have enabled absolute quantification and extremely high spatial resolution, allowing for a comprehensive understanding of subcellular processes.

Revolutionizing X-Ray Imaging with Interferometry

Researchers at the German Electron Synchrotron (DESY) have successfully demonstrated a novel x-ray imaging technique based on Hanbury Brown and Twiss interferometry, which can be used to image the structure of emitters on a copper film. The technique could eventually enable single-particle imaging of biomolecules and catalysts at the atomic scale, and, with sufficient time resolution, characterization of their reaction dynamics. The development of x-ray free-electron lasers (XFELs) has helped in this regard by making possible the generation of high-intensity x-ray pulses with femtosecond or even shorter durations.
