Atmospheric Air Pollution and Monitoring

Light detection and ranging (LIDAR) atmospheric sensing is a major tool for remote monitoring of aerosol pollution and its propagation in the atmosphere. Combining LIDAR sensing with ground-based aerosol monitoring can form the basis of integrated ai

Autor: L. Slavov, Georgi Kolarov, R. Angelova, Dimitar Stoyanov, Ivan Grigorov, Ivan Nedkov, Chavdar Ghelev, Ljuan L. Gurdev

Publikováno v: 20th International Conference and School on Quantum Electronics: Laser Physics and Applications.

In this work some features are revealed, simultaneously by LIDAR and contact facilities, of the aerosol pollutions near high-traffic sites in Sofia City. Such features of interest are the extinction coefficient of the aerosol ensembles and their mass

Publikováno v: AIP Conference Proceedings.

In this study, a LIDAR was used to outline characteristic zones in Sofia City of increased concentration of aerosol pollutants and to determine the related aerosol extinction coefficient. In-situ probing was conducted as well of the corresponding aer

Biogenic ferroxides derived from Leptothrix bacteria for applications in electronics, biomedicine and biotechnology

Autor: Blagoy Blagoev, L. Slavov, Veneta Groudeva, M. Iliev, R. Angelova, Ch. Ghelev, Ivan Nedkov

Publikováno v: IOP Conference Series: Materials Science and Engineering. 1056:012009

The present work is focused on studying by-products derived from the metabolism of bacteria of the Leptothrix genus, which are among the first described microorganisms associated with the iron cycle in nature. The products of their metabolism are nan
