Nanofilms Optimize Raman Thermometry for Extreme Manufacturing
Nanofilms Optimize Raman Thermometry for Extreme Manufacturing
Collaborating researchers demonstrated an approach to the thermal probing of nanomaterials in which the ratio of two resonance Raman peak intensities of a 2D material, tungsten disulfide (WS2), could be used as an indicator for high-sensitivity temperature measurements. The technique, called the Resonance Raman Ratio (R3) technique, precisely measured absolute temperature rise in nanomaterials.

Imaging Technique Enables Gas Leak Tracking in 3D
Imaging Technique Enables Gas Leak Tracking in 3D
Researchers developed a method to create a 3D image of a leaked gas cloud. The image provides detailed information about the leak, such as its location, volume, and concentration. The method combines information from two remote FTIR imaging systems with precise positioning information from gyroscope sensors and GPS to create a 3D image of the gas cloud superimposed on a Google Earth digital map.

Researchers Increase Spatiotemporal Resolution of Imaged Lightwaves
A multi-institutional team developed a technique to measure the electrical field of ultrashort laser pulses in time and space. The technique makes it possible to take “photographs” of lightwaves with a previously unachieved spatial and temporal resolution, and the development could in turn lead to an improved quality in spatially resolved spectroscopy.

Harnessing Photons for Bond-Selective Imaging, Neuromodulation, and the Killing of Superbugs Harnessing Photons for Bond-Selective Imaging, Neuromodulation, and the Killing of Superbugs
Tue, Nov 1, 2022 10:00 AM - 11:00 AM EDT
Chemical microscopy utilizing fingerprint vibrational spectroscopic signals opens a new window to visualize the orchestra of molecules and biological structures inside living systems. Dr. Ji-Xin Cheng, professor at Boston University, and his research team have recently started to harness photons to modulate the behavior of cells, including the photoacoustic modulation of neurons at ultrahigh spatial precision and photolysis of intrinsic chromophores to eradicate drug-resistant bacteria.
