Scientists have used ultracold atoms to successfully demonstrate a novel method of particle acceleration that could unlock a ...

Astronomers from Bulgaria and Egypt have performed multi-wavelength observations of a well-known blazar designated S5 ...

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit ...

A new analysis of BL Lacertae by NASA’s Imaging X-ray Polarimetry Explorer sheds light on the emission mechanisms of active ...

In the spectra, the emission peaks of the main components of sea water and contaminants from the electrodes were detected, and reference solutions were used for the identification of unassigned peaks.

To determine the optimal Yb ratio in this family of core/shell UCNPs, we characterized their red-emission outcome using spectrofluorimetry. Emission spectra under continuous wave (CW) 980 nm ...
