The fundamentals of promoter effects in the Fischer−Tropsch synthesis over Co-based catalysts were systematically investigated by employing the Rh, Ir, Sb and Ga as promoters of Co/Al 2 O 3 . Various characterizations showed the higher dispersion and reducibility over Rh- and Ir- promoted...

Influenced by many factors, farmers remain very unfavorable position in market transaction and thus fail to ensure their reasonable benefits. In accordance with basic theory of microeconomics, this paper analyzes mutual relation between market of agricultural means of production and agricultural...

Do physicians behave rationally when facing a new disease? This study assesses physicians’ ambiguity attitudes towards the COVID-19 pandemic at its early breakout and the stock market using a revealed preference approach. We find that physicians exhibit significant deviation from expected...

The quinoline insoluble (QI) in coal tar and coal tar pitch is an important factor affecting the properties of subsequent carbon materials. In this paper, catalytic polycondensation was used to remove QI from heavy coal tar, and mesocarbon microbeads could be formed during the purification...

VOCs emissions in the chemical industry have always contained a large proportion. Xylene with paint thinner as the main emission route is the research object of this paper. Xylene was used as the research object, nickel foam as catalyst carrier, goethite as catalyst active component....

We examine the rise of cloud computing and AI in China and its impact on industry dynamics. We find that industries that depend more on cloud infrastructure experience a higher increase in firm entry and exit after cloud computing expands in China. The positive relation with firm exit is driven...

We compare Bayesian with the two non-Bayesian updating under ambiguity in its model specification and numerical implications. For an ambiguity averse (seeking) decision maker, we find that Gilboa and Schmeidler (GS) updating leads to a lower (higher) certainty equivalent (CE) than...
