|Titel:||Atmospheric Nanoparticles: Formation and Effects - New insights from Mass Spectrometric measurements aboard Rockets, Balloons and airplanes|
Nanoparticles (NPs) are of considerable current interest, due to their environmental effects, including particularly climate and health effects. NPs are formed from nucleating gases in the earth´s atmosphere at altitudes between ground level and about 120 km. NP precursor gases include natural gases (meteor ablation gases, gases injected by volcanic eruptions) and man-made gases (aircraft engine emissions, car engine emissions). We have obtained new insights from our pioneering mass spectrometric measurements, conducted on rockets, stratospheric balloons and airplanes. The talk will focus on our recent rocket and aircraft measurements made by improved mass spectrometric instruments.

|Titel:||Nuclear Equation of State for Hot Dense Matter|
Nuclear equation of state (EOS) is constructed with energy density functional (EDF) and liquid drop model (LDM) technique.
Compared with the classical LDM approach containing alpha particle, deutron, triton, and helio are added to construct nuclear EOS.
Energy density functional parameters are constrained by theoretical neutron matter calculation, symmetric nuclear matter properties,
and maximum mass of neutron stars. The nuclear surface tension and the critical temperature necessary for the free energy of finite
nuclei are calculated in a consistent way.
In this talk, I will present and discuss the current results obtained from LDM and EDF with most recent parameters.
