Here, we present a hot injection synthesis of colloidal Ag chalcogenide nanocrystals (Ag(2)Se, Ag(2)Te, and Ag(2)S) that resulted in exceptionally small nanocrystal sizes in the range between 2 and 4 nm. Ag chalcogenide nanocrystals exhibit band gap energies within the near-infrared spectral region, making these materials promising as environmentally benign(More)
A strain of tissue of common rue of root origin (index of the strain R-4) has been obtained which produces up to 3% (of the dry weight) of acridone alkaloids. It has been shown by physicochemical methods that the combined alkaloids consist mainly of 1-hydroxy-N-methylacridone, rutacridone, and 1-hydroxy-3-methoxy N-methylacridone (0.28, 0.81, and 2.41 mg/g(More)
