In a DEMO fusion reactor, it is necessary to continuously extract deuterium and tritium from the unburned fuel gas under divertor panels. For the pumping system in the divertor, a new method of ...

Almost two-thirds of the world's population is affected by the monsoon—the annual arrival of intense rains in areas north and ...

The water-cooled lithium-lead (WCLL) test blanket module (TBM) of ITER and the respective breeding blanket (BB) of DEMO need to be efficiently characterized from the point of view of hydrogen isotopes ...

We investigated the mechanisms and isotope effects associated with the N-dealkylation and N-atom oxidation of substituted N-methyl- and N,N-dimethylanilines to identify isotope fractionation trends ...

The researchers examined five different elements' stable isotope ratios -- carbon, hydrogen, nitrogen, oxygen and sulfur -- to see which would distinguish most clearly between the samples.

Here, we report the isotope effect of hydrogen terminations in the layered Ge on lattice vibrations and electronic and atomic structures. We show that the Ge–Ge in-plane vibration responds to the mass ...

That indicates that targeting oxygen and hydrogen isotope ratios is the most effective way to differentiate between mammoth and elephant ivory samples, according to the researchers.
