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, ...

Photonic systems are quickly gaining traction in many emerging applications, including optical communications, lidar sensing, and medical imaging. However, the widespread adoption of photonics 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 ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Even after more than a century of research, one of the greatest mysteries about our Sun continues to remain unsolved.

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 ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...
