CuO nanoparticles (NPs) are widely used in commercial applications. With increasing CuO NPs production, CuO NPs are likely to present in the environment and pose a potential threaten to ecosystem. In this work, 20 and 50 mg/L CuO NPs and 0.15 mg/L Cu2+ were used to test the toxicity to Arabidopsis thaliana...

Particulate pollution is a major kind of atmospheric pollution. The fine particles are seriously harmful to human health and environment. Acoustic agglomeration has been proved as a promising pretreatment to control the emission of fine particles. Based on the acoustic agglomeration, this paper investigates...

Biodegradation of pyrene and indeno(1,2,3-cd)pyrene in reed rhizosphere soil was carried out in a small-scale wetland simulator using reed as well as microorganisms immobilized on cinder beads under natural environmental conditions. The results show that the stability of the introduced strains was enhanced...

Transmission pipelines carrying natural gas across long distances often work at high pressures (up to 10 MPa). The high-pressure natural gas is regulated though a throttling device, which results in much waste of pressure energy. Meanwhile, more pressure reducing stations exist the problem of no electric...
