Oxidation of atmospheric organic carbon : interconnecting volatile organic compounds, intermediate-volatility organic compounds, and organic aerosol
.Organic molecules have many important roles in the atmosphere, acting as climate and biogeochemical forcers, and in some cases as toxic pollutants. The lifecycle of atmospheric organic carbon is extremely complex, with reaction in multiple phases (gas, particle, aqueous) and at multiple …

Organic Space
My works evolve from a concrete vision but tend to lack recognizable imagery. Color and texture are central to my process. By isolating the element of color, I strive for purely formal qualities in my color field paintings. Working on textured suraces, such as burlap, allows me to capture textural …

Electronic properties of metal-organic and organic-organic interfaces studied by photoemission and photoabsorption spectroscopy
In this work systematic studies of the organic semiconductor CuPc have been presented. In general the investigation can be devided in three parts. In the first one we have studied the electronic structure of clean CuPc thin film. The next two parts are devoted to organic-organic and metal–organic …
