Heavy elements

This paper researched the use of ash from domestic waste incinerators to generate electricity and blast furnace slag for civil construction materials. Due to the presence of heavy metal elements in the ash from the domestic waste incinerator and the blast furnace slag, its use is limited.

By using an extensive three-dimensional discrete element method, we numerically investigate the effects of lightweight particle content on the mechanical strength of the cylindrical aggregates, randomly composed of two different groups of primary particles: light (low stiffness) and heavy (high stiffness), and the stress contribution of the heavy-heavy, light-heavy, and light-light interactions on the mechanical behavior of such aggregates, subjected to the compression test by using a constant downward velocity.

For the design of ADS (Accelerator Driven System), it is important to study neutron spectra and details of nuclear reactions induced by neutrons. Furthermore, neutron energy and angular distribution data are important for a correct simulation of the propagation of particles inside a spallation target and the geometrical distribution of the outgoing neutron flux.

The characteristics lines in X-ray spectra result from electronic transitions between inner atomic orbitals. The X-ray spectra for most heavy elements are much simpler than the UV/Vis spectra observed in ICP-OES, for example. (Only a few lines!!!) Big difference between X-ray and UVVis: The radiation is ionizing, and doesn’t just excite electrons to higher levels. Moseley’s law: Predicts the basic relationship of atom number and the frequency of the characteristic lines

Finally, electromagnetic bearings involve complex design problems to ensure that the heavy spindle, with its high inertia, does not fall and damage the magnetic bearing when power is shut off or momentarily discontinued. Therefore, a noninterrupted power supply is required to operate the magnetic bearing, even at no load or at shutdown conditions of the system. In order to secure safe operation in case of accidental power failure or support of the rotor during shutdown of the machine, an auxiliary bearing is required. Rolling-element bearings with large clearance are commonly used.
