What is the mass number for carbon? Isotopes: Isotopes are atoms of the same element that have a different number of neutrons. They can be identified because they will also have a different mass number, or the mass of one atom of the element. ...

Subsequently, the 18O abundance and total O content were determined using an elemental analyzer (FLASH 2000, Thermo Fisher Scientific, Cambridge, UK) coupled with an isotope ratio mass spectrometer (IRMS) system (ConFlo VI interface and MAT253 IRMS, Thermo Scientific, Bremen, Germany) at the ...
The thus obtained Möbius belt 1 was characterized using high-resolution mass spectrometry and NMR spectroscopy. The high-resolution mass spectrum showed an isotope pattern with its highest peak at 3,944.9449, which is in good agreement with the simulated pattern and mass number (m/z = 3...
Volkswagen Anhui is sprinting towards the pre-series production of its first NEV model next month, and its mass production is scheduled for 2023. Anhui has already gathered many world-renowned NEV manufacturers, including Volkswagen, JAC, Chery, NIO, and BYD, and key NEV industrial suppliers. Th...

The era of carbon-based nanotechnology, as it is well-known, started from 1985 when the fullerene C60 was discovered. The rediscovery of carbon nanotubes and unexpected discovery of graphene gave a powerful impulse to the further development of carbon na
GmFULa has an important role in plant architecture through regulating the branch number, node number, leaf size, and leaf thickness. However, GmFULa had no significant effect on plant height when overexpressed. Moreover, it promoted the dry mass accumulation of both root and shoot and ultimately...
