Nanostructured rare earth cuprates have recently attracted extensive attention as a promising non-noble metal electrocatalyst. However, they are rarely used to construct electrochemical sensors, even no report on important hydrogen peroxide. Accordingly, simple sol-gel method plus air...

This paper argues that urbanization reshapes individual's risk preference by exerting self-selection and assimilation effects. Taking advantage of the unique hukou system in the People's Republic of China, we initiate a quasi-experiment method to elicit the two effects, employing the 2013-wave...

Foreign Direct Investments (FDI) are often considered long-term and less sensitive to global shocks as they involve large amounts of capital investment that are costly to reverse. This study examines whether a pandemic arbitrage through “distance” in COVID-19 infection rates impacts FDI....

Electrochemical determination of luteolin is vital to food industry owing to its bioactive properties such as anti-viral, anti-ulcer, while bare electrode of traditional electrochemical sensors generally have narrow linear range and low sensitivity, limiting their practical application....
