Neophytes in Austria: Habitat preferences and ecological effects
Alien species are acknowledged as a major threat to the conservation of global biodiversity (e.g. Sala et al. 2000; McNeely et al. 2001; Cronk & Fuller 2001; Sukopp 2002; Cox 2004). While detailedExpand

Using carbon nanodots as inexpensive and environmentally friendly sensitizers in mesoscopic solar cells.
We discuss the use of carbon nanodots (CNDs) as sensitizers in mesoscopic solar cells. The CNDs are synthesized using a one-step, bottom-up microwave approach with citric acid, urea, and formic acidExpand
