Molecular-dynamics simulation of ejection processes in electronically excited solid Ne

Molecular-dynamics simulation of particle ejection from solid neon has been carried out for the first time. We have studied the emission dynamics in the lattice around a 3s exciton in the near-surface layers. Excited- as well as ground-state atoms are ejected as a result of lattice relaxation. The energy of ejected particles agrees well with existing experimental results

Morphological characteristics and transport coefficients for reticulated vitreous carbon (RVC) foams

W pracy przedstawiono parametry morfologiczne oraz współczynniki transportowe dla szklistych pian węglowych (RVC) o gęstości porów wynoszącej 30 i 80 PPI. Parametry morfologiczne pian określono za pomocą mikrotomografu SkySkan 1172. Współczynniki wnikania ciepła wyznaczono ogrzewając pianę przepływającym przez nią prądem elektrycznym. Współczynniki wnikania masy wyznaczono w oparciu o analogię Chiltona-Colburna.In this paper, the morphological parameters and transport coefficients are studied for the reticulated vitreous carbon (RVC) foams of pore density 30 and 80 PPI. SkySkan 1172 X-ray microtomograph was used to study the foam structure. Heat transfer coefficients were determined by foam heating by electric current flowing directly through it. Mass transfer coefficients were determined based on the Chilton-Colburn analogy
