The spread of the antibiotic oxytetracycline (OTC) has been thought as a threat to the safety of drinking water. In this paper, the photocatalytic activity of the nanocrystalline Fe/Ca co-doped TiO2-SiO2 composite film for the degradation of OTC was studied. The films were characterized by field...

The micro-laminated (ZrO2–Y2O3)/(Al2O3–Y2O3) composite coatings were prepared on the surface of Fe–25Cr alloy by an electrochemical process and a sintering process alternately. FE-SEM analyses show that the cross section of the micro-laminated coatings has alternate six-layer films of...

Hydrogen production from NaBH4 hydrolysis is very important for environment-friendly fuel cells. Here Y-zeolite/CoCl2 doped PVDF (Polyvinylidene fluoride) composite nanofibers were prepared by co-electrospinning method and successfully applied into hydrogen production from NaBH4 hydrolysis. The...

This paper studies the role of shareholder activism on corporate leases. We find that the presence of shareholder activists is associated with large increases in leasing. This association is stronger in periods of high real estate prices and for firms with larger amounts of real estate assets....
