NASA and ESA’s Hubble and Euclid telescopes provide a new image of the Cat’s Eye Nebula, showing detailed structures and previously unused data for updated views of NGC 6543.

Abstract: Absorption spectroscopy has been widely used in non-intrusive chemical analysis. Dual-comb spectroscopy is emerging as an effective tool for the measurement of absorption spectroscopy with ...

ISO/TS 17466 (Use of UV/Vis absorption spectroscopy in the evaluation of cadmium chalcogenide colloidal quantum dots, 2015) defines a direct relationship between the first excitonic absorption peak ...

The polymer solar cell is able to retain 97% of its performance after 2,000 hours in air. By blending small-molecule acceptors into polymeric matrices, the research team improved molecular packing, ...

The total lunar eclipse on March 3, 2026 will feature a rare navy blue fringe caused by the ozone layer. This stunning ...

A study shows that cathodic hydrogen charging affects the integrity of stainless steel, revealing links between surface morphology, hydrogen uptake, and impurity deposits.

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...

The next ORION program will take place at 7 pm Wednesday, May 21, in the City Room (Room A-111), McNally-Coffey building, Roane State Community College, Oak Ridge campus. The title of the program is ...

The UV-Vis spectrum is a graphical representation of light absorption. Wavelength (nm) is shown on the x-axis, representing the energy of absorbed light; absorbance or transmittance is plotted on the ...

Atomic absorption is similar to the ICP in that it can determine the concentration of metals, but it has some limitations. In GFAAS, the sample is heated electrically in a graphite tube to create a ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Ultrafast spectroscopy has made it possible to observe a wide ...
