Astronomers from the UNIGE have observed the composition of the gases in our galaxy and have shown that, contrary to the models established until now, they are not homogeneously mixed. In order to ...

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments now show that this view is too simplistic. Their results solve a key problem ...

Quantitative Micro-XRF analysis incorporates data across the whole irradiated and detected sample area. The quantification method requires a homogeneous sample to properly determine its composition.

In order to better understand the history and evolution of the Milky Way, astronomers are studying the composition of the gases and metals that make up an important part of our galaxy. Three main ...
