A novel anti-Pb poisoning Sm and Fe co-doped Mn-Ce/AC catalyst was prepared by impregnation method for low-temperature NH3-SCR of NO reaction. Maintaining the excellent low-temperature activity of Mn-Ce/AC catalyst, Sm and Fe co-doping remarkably enhanced the catalyst’s Pb-resistance, with NO...

The development of catalysts with high NH3 -SCR activity in the presence of SO2 was urgent for non-electric industries to control NOx emission at low temperature. Herein, a series of Sm-doping MnFeOx catalysts were synthesized through a typical PEG-assisted co-precipitation method and applied...

In this study, a new type of water-soluble polysaccharide was extracted and purified from mussels, and its structure and cellular antioxidant levels were studied. Mussel polysaccharide (MP 4.25×10 3 Da) is composed mainly of glucose, with a small amount of galactosamine hydrochloride,...

We analyse the allocation of face masks with the goal of minimizing mortality during a pandemic through airborne transmission. When the initial distribution of masks is private information, the optimal allocation achieved by a sophisticated mechanism in most cases maximizes the coverage rate by...

Stock market movements are the results of changes in investor sentiment (INSEN) which can even be induced by non-economic events. We consider international cricket events to empirically investigate the notions. Implementing portfolio approach, we conduct the event study along with OLS regression...

The recent outbreak of global COVID-19 infections has already accounted for thousands of deaths, sealed many businesses, and urged millions of people to be unemployed, pushing the global financial markets to the edge of another gigantic crisis. This study employs cross-correlation-based absolute...
