Exploring the association between sleep problems and loneliness in adolescents: Potential mediating effects of rumination and resilience.

Sleep problems positively predict loneliness to a large extent, which would harm adolescent health. However, little is known about the underlying mechanism. This research investigates the potential mediating roles of rumination and resilience in the relation among adolescents and further examines the changing relationships.

Template-free method for the synthesis of high-pore-volume γ-AlO nanofibers in a membrane dispersion microreactor.

Mesoporous γ-AlO nanofibers with high pore volume and uniform pore size distributions were successfully synthesized via a template-free method in a membrane dispersion microreactor followed by calcination. The effects of crystal temperature, pH values, continuous phase concentration and washing solvent on the γ-AlO nanofibers were carefully studied. The results showed that the as-obtained γ-AlO nanofibers showed a length of 40-60 nm and a width of 3.
