The use of a low-temperature plasma for the synthesis amorphous silicon carbonitride (SiCN) nanoparticles enables realization sintered bulk samples with high thermal stability. Amorphous SiCN are produced from mixture silane, methane, and ammonia utilizing mid-pressure, radio-frequency, continuous flow reactor. Particle characterization shows that largely some crystalline carbide domains <10 nm...

The nonthermal source abundances of elements play a crucial role in the understanding cosmic ray (CR) phenomena from few GeV up to several tens EeV. We present first systematic approach describe change thermal state via diffusive shock acceleration by temporally evolving shock. consider hereby not only ionization states contained ambient gas, which we allow be time dependent due heating, but al...
