A mass spectrometer is an instrument which ionizes a sample, separates the ions depending on their mass-to-charge ratio, and measures the intensity of the ions present at different mass-to-charge ratios. This can be used to determine the elements or isotopes present in the sample. The techni...
StellarNet Raman Spectrometer Raman spectroscopy is based on the interaction of light (typically a laser) with a material’s chemical bonds. Light is scattered directly off the sample and passed through a filter to remove the particles from Rayleigh scattering. ...
In this work Talys calculations of155Tb cross section have been benchmarked with data measured by Dellepiane et al. [10] with an enriched155Gd target. The contribution of each isotopic component has been disentangled to expose the effects deriving from the impurities of the target. Once the mo...
"We have measured an excess of positrons [the antimatter counterpart to an electron], and this excess can come from dark matter," Samuel Ting, AMS lead scientist and a Nobel laureate with the Massachusetts Institute of Technology, told Space.com. "But at this moment, we still need more da...
This guide explains what machine learning is, how it is related to artificial intelligence, how it works and why it matters.
Why must the mass of an anhydrous salt be measured immediately upon cooling? Why does a hot beaker's mass not stabilize on a mass balance? Why is it necessary to use the same weighing dish used to tare (zero) the balance to mass a substance? What is the goa...
Earthquake: An earthquake in simple words is the shaking of the earth. It is caused by the release of energy that generates a wave that travels in all directions. These waves are termed seismic waves. Answer and Explanation:1 Richter scale and Mercalli scales are...
Proper motions measured in some objects are sub-relativistic. Other processes, such as synchrotron radiation from shock-accelerated gas around the outflows could give rise to radio emissions as well. Near the launching region, these outflows may be driven by the thermal energy of the accretion ...
Schroeder and Christensen [9] entitled a subchapter “Scab resistance as measured by the number of infected seeds”. This was forgotten, but this was maybe the first occasion when FDK was used for resistance evaluation against FHB. Of course, the FDK as a phenomenon has been known for about...
