Bioethanol is an essential energy source and is produced from agricultural feedstocks. However, raw bioethanol contains much water and methanol, and the traditional distillation approach has hardly removed it. Adsorptive separation of ethanol from water and methanol by adsorbents is an...

The shallow penetration depth of the sealant was often the main reason affecting its long-term protection. For the purpose of improving the penetration depth of the sealant and prolong its durability, an ultrasonic-assisted pre-sealing, annealing plus post-impregnating integration sealing method...

We study how air pollution affects firm dynamics: entry, exit, innovation, and (aggregate) productivity. Using an instrumental variable strategy, we find that air pollution significantly reduces entry and innovation and raises exit. Moreover, air pollution leaves firms with higher productivity...

We propose a dynamic semi-parametric framework to study time variation in tail parameters. The framework builds on the Generalized Pareto Distribution (GPD) for modeling peaks over thresholds as in Extreme Value Theory, but casts the model in a conditional framework to allow for time-variation...
