Ultraviolet spectroscopy plays a critical role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are essential for tests of fundamental physics, ...

High-quality femtosecond light sources are critical for developing advanced time- and angle-resolved photoemission spectroscopy (TrARPES), which is powerful in capturing the electronic dynamics in ...

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 ...

Researchers developed an AI-guided method that dramatically speeds up a widely used X-ray technique known as X-ray absorption near-edge structure (XANES) spectroscopy. It does so with far less risk of ...

Near-infrared spectroscopy (NIRS) is a noninvasive method used to monitor changes in hemoglobin concentration and oxygen levels in the body. This technique involves passing near-infrared light, ...

Figure 1. Schematic diagrams of CF-LITES and CF-H-LITES detection system. (a) The detailed diagram of the QTF. (b) The figure of the self-designed T-shaped QTF. Σ: adder; TA: trans-impedance amplifier ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
