Understanding and predicting population responses to climate change is a crucial challenge. A key component of population responses to climate change are cases in which focal biological rates (e.g.

Due to its excellent hydrogenation ability, nickel has been widely studied and has shown good activities in CO hydrogenation reactions, in addition to its high availability and low price. However, Ni-based catalysts are prone to sintering under elevated temperatures, leading to unstable catalytic performance.

On the other hand, the atmospheric concentration of CH has raced past 1,900 ppb in 2021, almost triple its pre-industrial levels. As a greenhouse gas at least 86 times as potent as carbon dioxide (CO) over 20 years, CH is becoming a major threat to the global goal of deviating Earth temperature from the +2°C scenario.

They show high thermal stability like ceramics, but they are also tough, ductile, and good conductors of heat and electricity like metals. Here, we study the potential of the TiAlC MAX phase as a support for molybdenum oxide for the reverse water-gas shift (RWGS) reaction, comparing this new catalyst to more traditional materials.

With increasing constraints on resources and the environment, it is of great practical importance to discover and utilize the induced effect of green technology through market-based tools, in order to simultaneously realize economic development and ecological sustainability. Based on unique patent data from 1999 to 2013, this paper examines the induced effect of China's increasing-block electricity pricing scheme (IBP) on energy-efficient patents and checks whether the effect is neutral or biased. Furthermore, the quality of the induced patents is identified.

Applying the generalized difference-in-difference-in-differences method, this analysis takes the province-managing-county reform as a quasi-natural experiment for decentralization and shows that four indexes of water quality in reformed counties near city borders are 10%-20% better than that of otherwise identical counties. This study suggests that the reform has a positive effect on environments near borders, which is attributed to the mitigation effect of increased public revenue, the mechanization effect of mechanized agriculture, and the home market effect of a narrowed market.
