Abstract:
... Cropland abandonment has emerged as a common phenomenon in land use transitions. Both cropland abandonment and Payment for Ecosystem Services (PES) programs can facilitate the provision of ecosystem services. However, the relationship between cropland abandonment and PES programs remains poorly understood. China has recently undergone considerable cropland abandonment in mountainous areas. Meanwhi ...

Heat-induced whey protein hydrogels labeled with Rhodamine B isothiocyanate (RITC) were used as a model system. Complications in the quantification of Q using fluorescence of proteins conjugated with RITC, arisin ...

The potential of combining the sorption capability of CNTs with bacterial degradation for pollutant removal, however, necessitates further investigation of the mechanisms of CNTs’ toxicity towards bacterial cells. In this study, we used a panel of stress-responsive recombinant ...

Abstract:
... Alkali species in coal play an important role in mineral matter reactions during gasification. Brown coal ashes can be high in sodium (up to 20 wt%), which interacts with other minerals to significantly affect the formation of slag (liquid phase). At high temperatures, sodium in slag affects phase equilibria, liquidus temperature, and slag viscosity. We investigated phase transformations in brown ...

Batch experiments and XPS analyses confirmed that in a binary system, the presence of Sb(V) exhibited a slight synergistic effect on As(V) adsorption. XPS analyses showed that As(V) and Sb(V) adsorption led to obvious diminishment of Fe–O–Fe and Fe–O–H bonds respectively. At pH ...

Abstract:
... Fuelwood is an essential environmental good for livelihood in rural China. Heavy reliance on fuelwood is associated with numerous negative externalities. Due to decades of rapid economic growth in China, we hypothesize that the increase in rural household income would reduce reliance on fuelwood. Using data from a survey of 481 households conducted in 2014, we examined the effects of two payments ...
