Modern dosimetry needs efficient detectors for registering light ions, especially light ions having energies of up to 10MeV/amu. That is why this research pays attention to the development of materials for such a task. In this work, a CR-39 detector, which is the most efficient detector, was...
Electrons are tiny (0.000549 amu), negatively charged particles that are described as orbiting the protons and neutrons that make up an atom's nucleus, in the manner of planets orbiting the sun. This is a rough description at best, however, as advances in quantum physics have led to the co...
where R(cm)R(cm) is the total range in cm of alpha particle in an absorber, A is the atomic weight of the solid or liquid, and ρρ is the density of the medium. 5 Stopping time It determines how long it takes for the particle to come to a complete stop and lose its kinetic ...
This supports the observed larger aavg of the PEI60000-coated nanoparticles in DLS patterns. Furthermore, the broader DLS pattern of the PEI60000-coated nanoparticles is attributed to the higher polydispersity [48] (i.e., molecular weight broadness = Mw/Mn = 12.5) of PEI60000 compared with ...
This is because most of the fluid is in gas phase. To gain full market recognition, the Fuel Cell industry is currently battling with high weight, short lifespan, high cost, and low power density. Researchers are working on all the cell components to alleviate the aforementioned challenges. ...
