Despite recent improvement in therapy, acute myeloid leukemia (AML) is still associated with high lethality. In the presented study, we analyzed the bioactive compound iodinin (1,6-dihydroxyphenazine 5,10-dioxide) from a marine actinomycetes bacteriu

A known drawback using chemical absorbents in post-combustion CO2 capture is degradation of solvents, which increases the capture cost and produces unwanted compounds from a health and environmental perspective. Validation of lab results is necessary

Nitrosamines (NSAs) and nitramines (NAs) are identified as possible degradation products from amine-based post-combustion CO2-capture (PCCC). Selected NSAs and NAs were subjected to aerobic and anaerobic biodegradation studies. In a screening study w

Amine solvents used in post combustion CO2 capture (PCCC) plants react with NOx, forming carcinogenic nitrosamine and nitramine compounds. These can be emitted to the atmosphere, undergoing deposition to aquatic and terrestrial environments. In the c
