A pilot-scale mangrove wetland was constructed in Futian, Shenzhen for municipal sewage treatment. Three identical belts (length: 33m, width: 3m, depth: 0.5m) were filled with stone (bottom), gravel and mangrove sand (surface). Seedlings of two native mangrove species (Kandelia candel, Aegiceras corniculatum) and one exotic species (Sonneratia caseolaris)(More)

This study reports a novel method for tuning thin film mechanical properties by means of plasma surface modification. According to the experiment results, the formation of Si-N chemical bonds on the surface of SiO<sub>2</sub> film will lead to an equivalent gradient residual stress; moreover, this gradient residual stress can be easily tuned by varying the(More)
