A novel chitosan stabilized biochar supported sulfide nano-zero valent iron composite material (CB- S-nZVI ) was prepared to high effectively remove Cd2+ and Cu2+ from wastewater. Batch experiments showed that CB-S-nZVI had higher affinity for Cd2+ and Cu2+ than other nZVI modified materials....

The spray of ethanol-biodiesel at ultra-high injection pressure, different ambient pressures and temperatures under transient flow in the coupled nozzle was characterized, and sensitivity of the maximum particle concentration under different conditions was analyzed. A three-dimensional...
