If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Answer and Explanation: The atomic number is equal to the number of protons in an atom. ...
nanocrystalline structure is found within an amorphous matrix. We also observe substantial density fluctuations in the APT density map of the oxide in Supplementary Fig.10, a feature which has been reported before as a clear indication for the formation of nanocrystals and grain boundaries43. This ...

In particular, the bulk halide perovskite such as CsPbBr3, which possesses one of the simplest halide perovskite structures, is a good benchmark system to understand the fundamental physical mechanisms but already presents several outstanding questions. First, what is the intrinsic τs of CsPbBr3?

And that's right -- sort of. Curie actually discovered the element radium in 1898, an accomplishment that would make her the first female recipient of the Nobel Prize. However, three years earlier in 1895, a scientist named Wilhelm Röntgen first discovered X-rays and the phenomenon of ...
The so-called “branching points” in the nuclear s-process nucleosynthesis (e.g.60Fe,79Se), radionuclides produced via the p-process (e.g.148/150Gd,146Sm,154Dy) as well as several other long-lived isotopes, are of high relevance for the understanding of the element formation in the ea...
First, let's talk air. We all need oxygen, so the ISS has several methods of providing it. One technique is to have oxygen delivered from Earth via spacecraft. Supply shuttles periodically arrive with fresh oxygen in tow; the life-giving element is deposited into pressurized tanks aboard the...
