Abstract:
... The wasp Trypoxylon lactitarse Saussure is a bivoltine trap-nesting species that possesses a non-overwintering generation (G1) and a generation that overwinters as a prepupa (G2). Thus, the nutritional needs of the G1 individuals were predicted to be different than the G2 because the latter generation needs to store energy prior to diapause. Trap-nesting Trypoxylon are also of interest because, un ...

Abstract:
... Catalytic reactions of zeolites occur mainly at their acid sites; however, there is a lack of comprehensive method to characterize the acid sites by multiple aspects due to their complexity associated with both the host structures and the origins of formation. Here we propose a comprehensive computational approach, from both thermodynamic and kinetic points of view, to evaluate jointly the energet ...

Abstract:
... A flexible and stretchable three-dimensional carbon electrode (SCF) based on the natural woven fabric was developed by coupling a sublimation generating pores method and facile pyrolyzing procedure. The SCF electrode possessed good mechanical flexibility, which was attributed to the increase in the specific surface area and the amount of the pores. Furthermore, the SCF electrode exhibited excellen ...

Abstract:
... A new method using polyphosphate kinase (PPK) probe was developed in this study to measure the ratio of denitrifying phosphate-accumulating organisms (DNPAOs) to bacteria. Advantages and disadvantages of this method and previously published methods were evaluated. Biochemical characteristics and metabolic mechanisms of the bacterial community in activated sludge were analyzed. The result indicated ...

Abstract:
... Efficient large scale electrochemical energy storage systems, such as those based on multivalent ions, are a prerequisite for the realization of intermittent renewable energy sources. From the perspectives of both cost and environmental concerns, it is of critical importance that components of these systems are synthesized using sustainable chemical processes starting from their initial conception ...

Abstract:
... The ambition to develop a bioeconomy depends largely on the forest-based sector. For creating higher-value chains, technological innovations are sought in the field of lignocellulosic biorefining. Although biorefinery concepts have been under development for decades now in Germany, many relevant technological developments are still confined to the laboratory and pilot scale. By taking on a technol ...
