Abstract By reducing potassium permanganate using various methods (microwave radiation, HCl, ethanol, ascorbic acid) in a biochar environment, we have prepared composites of manganese oxides and biochar as an electrode material for elements or supercapacitors. Once identified, the prepared products were tested for thermal stability and phytotoxicity as a safety parameter in case they get in contact with the natural environment. The publication had also discussed progression of thermal decomposition of the composite. The process was exo-thermal with mutual oxidation-reduction reaction between the manganese oxides and biochar carbon. In the article there are also described the adsorption capabilities of prepared products. The manganese oxide content had also influenced the phytotoxicity test results. The biochar itself had stimulating effects on all tested seeds, while composites had shown both stimulating and inhibiting effects, depending on the kind of tested seeds.

Flue Gas Desulphurization

With the beginning of the characteristics of sintering flue gas, the thermodynamics and chemical reaction mechanism of sintering flue gas desulphurization with pyrolusite slurry were analyzed and discussed in the paper. Results shown that the main chemical reaction was oxidation-reduction reaction of sulfur dioxide and manganese dioxide with a high reaction velocity and desulphurization efficiency at the first stage. The reaction speed and the desulphurization efficiency decreased gradually and Mn2+is used as catalyst in the desulphurization reaction with the proceeding of chemical reaction and decreasing of PH value of solution.

Opportunistic bacteria Pseudomonas aeruginosa is one of the major concerns as an etiological agent of nosocomial infections in humans. Many virulence factors used to colonize the human body are the same as those used by P. aeruginosa to thrive in the environment such as membrane transport, biofilm formation, oxidation/reduction reaction, among others. P. aeruginosa origin is mainly from the environment, the adaptation to mammalian tissues may follow a source-sink evolution model; the environment is the source of many lineages, some of them capable of adaptation to the human body. Some lineages may adapt to humans and go through reductive evolution in which some genes are lost.  The understanding of this process may be critical to implement better methods to control outbreaks in hospitals.
