TA was used to measure the absorption from the transient triplet state, while laser-induced fluorescence (LIF) spectra measured photoluminescence emission. Data was acquired for both degassed and ...

A NEW series of observations of the galactic radio emission has been conducted at the frequencies of 20, 30 and 85 Mc/s. These low-resolution observations made with scaled aerials were intended to ...

The LAMOST spectra revealed that the investigated regions of G206.7+5.9 showcase large ionized sulfur and ionized nitrogen to hydrogen-alpha ratios. This suggests that the emission primarily ...

Plasma emission spectroscopy revealed the degradation process is mainly attributed to reactive oxygen species (ROS), while the role of reactive nitrogen ... a concentration density similar to that ...

Scientists recently reported an unexpected deep-sea development in the Pacific: certain metallic rocks seem to be making oxygen in the dark, without light or sunshine, at the bottom of the ocean. This ...

Furthermore, the observations detected Balmer, oxygen, nitrogen, and helium emission lines in the spectra of V1425 Aql's nova shell. It turned out that the outer ejecta is only visible in the so ...

Roula Khalaf, Editor of the FT, selects her favourite stories in this weekly newsletter. Sir Keir Starmer is looking to relink the UK and EU emission trading schemes in a sign of the prime ...

In the present study, oxygen concentrations up to ∼50 mM were used, resulting in a more accurate determination of the static quenching constant. Absorption spectra obtained at higher oxygen ...

Before them stood a silvery metal contraption swathed in colourful wires – a box that they hope will one day make oxygen on the moon. Once the team vacated the sphere, the experiment began.
