We are engaged in the production and processing of cosmic dust analogs such as silicates and carbonaceous  materials and their structural and spectral characterization. We are also interested in the spectral properties of interstellar grains. The cosmic dust introduces the problems of solid state and surface physics into astrophysics.

Analytical Tools we use for the determination of the chemical composition, internal structure, chemical and structural homogeneity of the cosmic dust analogs are transmission and high resolution transmission electron microscopy (TEM, HRTEM), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), electron energy loss spectroscopy (EELS), nuclear magnetic resonance (NMR) spectroscopy, Raman spectroscopy, X-ray diffraction, wet-chemical analyses.
Spectroscopical Tools we apply for measurements of the spectral properties and derivation of optical constants are EELS, FUV, UV/VIS and IR spectroscopy (110nm - 800micron, reflectance and transmission), scattering measurements in the UV/VIS with the integration sphere.
