Study on the Microplastics’ Effect on the Life History of Daphnia magna [PDF]

E3S Web of Conferences
Microplastics (MPs), a type of new pollutant, have shown negative impacts on the aquatic environment. To understand how MPs impact zooplanktons, we studied the life history of Daphnia magna. D.

Three-dimensional assembly structure of anatase TiO2 hollow microspheres with enhanced photocatalytic performance

Results in Physics, 2017
The pure anatase TiO2 hollow microspheres are synthesized by a one-step template-free hydrothermal route. By defining temperature and time limits, we produce TiO2 hollow microspheres with a fluoride-mediated self-transformation. The surface morphology of
