Generation and Reactivity of a One-electron Oxidized Manganese(V) Imido Complex bearing a Macrocyclic Tetraamido Ligand
No full textThe synthesis and X‐ray structure of a new manganese(V) mesitylimido complex with a tetraamido macrocyclic ligand (TAML), [MnV(TAML)(N‐Mes)]− (1), are reported. Compound 1 is oxidized by [(p‐BrC6H4)3N]+.[SbCl6]− and the resulting MnVI species readily undergoes H‐atom transfer and nitrene transfer reactions
Study of Synthesis of Biodegradable Plastics from Alkaline Fermented Excessive Activated Sludge
No full textThe environmental problems associated with plastics have become increasingly severe in recent years. Technologically and economically feasible solutions are in urgent need in order to ensure sustainable development in the plastic industry. Polyhydroxyalkanoates (PHAs) are a family of specialized polyesters of hydroxyalkanoates (HAs) and can be completely degraded in natural environment. They can be synthesized naturally or under artificially controlled processes. The barrier of limiting the application of PHAs is the high production cost. From years of study, PHAs are proofed to be able to be accumulated within the bacterial cells in activated sludge and the production yield had been greatly improved under the optimized Carbon to Nitrogen (C:N) Ratio and Carbon to Phosphorus (C:P) ratio. Therefore, PHAs synthesis is able to combine with wastewater treatment. However, high carbon source is still required for a higher production yield to offer substrate pressure for PHAs accumulation. On other hand, wastewater treatment plants produce large amount of excessive activated sludge (EAS) to send to landfill sites. This study aims to investigate the PHAs synthesis of PHAs from the fermented EAS via ferrous activated persulfate oxidation method and analyze the composition of the PHAs under various fermented sludge and wastewater. EAS samples were digested with combination of potassium monopersulfate, potassium bisulfate and potassium sulfate and ferrous sulfate to obtain the optimal concentration based on the digestion of EPS and intracellular substances. The optimized digested sludge was served as carbon source together with raw sewage for PHAs production. The ratio of Hydroxybutyrate (HB) to Hydroxybutyrate (HV) was investigated to reveal the relation with the digested sludge dosage. The outcomes of this study provide fruitful solutions to reduce the production cost of PHAs and maximize the reuse of EAS in wastewater treatment proces
Laboratory tests on evaluating the performance of road base materials using medium percentage of RAP
No full textIn order to investigate the performance of road base mixtures with high percentage of RAP, a systematic laboratory study was carried out. Road base mixtures with three RAP contents (0%, 30% and 50%), two RAP sources (road base and polymer modified friction course) and a recycling agent were designed. A series of performance tests were conducted, which took into account of the effects of temperature and aging on stiffness, fatigue resistance, water resistance and permanent deformation resistance ability. The results indicated that recycling agent could restore the stiffness and fatigue resistance of RAP mixture, while the rejuvenated RAP mixtures could maintain a higher water resistance and permanent deformation resistance ability. Mixtures incorporated with RAP could lead to a higher capacity in spreading traffic loading due to the increasing of stiffness. The water resistance and permanent deformation resistance ability enhanced with increasing RAP content. However, the fatigue resistance reduced with increasing of RAP content. Mixture incorporating 30% content of RAP without recycling agent may perform better than that of virgin mixtures except a minor loss in fatigue resistance for the long run. The study would hopefully provide some insights into the application of high percentage of RAP in road base materials for sustainable pavement construction
