The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This phenomenon is ...

Photon upconversion (UC) occurs when two or more lower-energy photons are converted into higher-energy ones. Upconversion nanoparticles (UCNPs) are a key type of upconversion material. UCNPs are ...

Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because ...

We recommend using your OS's package manager directly instead for improved security but the install script is by no means insecure. In addition to being a runnable CLI tool, D2 can also be used to ...

(15−20) While some of these approaches achieve considerable sensitivity, they are all limited either by the data throughput (spectra/s, minimum sample volume, temporal resolution), the complexity in ...

X-ray spectroscopy reveals iron’s structure under extreme conditions Study provides insights into Earth's core melting and phase stability Findings challenge past theories and refine geodynamic models ...

You are free to share (copy and redistribute) this article in any medium or format and to adapt (remix, transform, and build upon) the material for any purpose, even commercially within the parameters ...

This study verified the feasibility of dielectric spectroscopy (DES) as a method for detecting abnormalities before damage occurs. A comparative evaluation was conducted between dielectric relaxation ...

Surface-enhanced Raman spectroscopy (SERS) has been widely used in the analysis of analytes because of its unique fingerprint characteristics, high sensitivity, and fast detection response. MXene is ...
