The discovery of naturally occurring catalytic RNA (RNA enzymes, or ribozymes) in the 1980s immediately revised the view of RNA as a passive messenger that solely carries information from DNA to proteins. Because DNA and RNA differ only by the absence or presence of a 2'-hydroxyl group on each ribose ring of the polymer, the question of 'catalytic DNA?' arises. Although no natural DNA catalysts...

This work reports supercritical water oxidation (SCWO) of organic pollutants in industrial wastewater the absence and presence catalysts. To increase efficiency process, SCWO compounds was performed various iron- manganese-containing heterogeneous catalysts (Fe-Ac, Fe-OH, Mn-Al). The catalytic non-catalytic from PJSC “Nizhnekamskneftekhim”, generated epoxidation propylene with ethylbenzene hydr...

Installing a catalytic converter in the exhaust is typical method of reducing engine emissions. Catalytic converters have been shown to lower pollutants while enhancing performance. The influence number brass catalyst plates (Cu-Zn) on Performance commercial Yamaha Jupiter MX motorcycle manufactured 2007 was investigated this study. installed motorbike exhaust, with varying between 5 and 8, con...
