Photoelectric characteristics are very important for discharge plasma. A volume diffuse dielectric barrier discharge (DBD) by means of parallel-plate arrays was established, and the methods including electrical parameter and optical emission spectroscopy (OES) were used to diagnose the discharge parameters. The results show that the spectra from discharge both in air and water mist have same trends,...
The reactions have been accompanied ultraviolet (UV) radiation and electron impact with discharge plasmas in water-gas mixture, which can generate oxides such as ozone (O3), hydrogen peroxide (H2O2) and nitrogen oxides (NOx). Two plasma processing systems were established by means of a dielectric barrier discharge (DBD) arrays in water mist spray and an atmospheric pressure plasma jet (APPJ) immersed...
Dispersion of lanthanum hexaboride (LaB6) nanoparticles in water and in sol-gel silica was investigated. The average size of lanthanum hexaboride nanoparticles/agglomenties decreases with increasing magnitude of the zeta potential in water with and without citric acid. Citrate-coated LaB6 nanoparticles were freeze-dried and mixed with TEOS/ethanol/water/HCl to disperse the nanoparticles in the sol-gel...
The vision of Cities as forces for good within the environment is explored herein by proposing a multisectoral analysis that accounts for nutrients, water, energy. The main purpose is to identify those elements in the urban system that can offer more opportunities of improvement with regard to eco-efficiency and eco-effectiveness indicators, and how different sectors, i.e. water, food, forestry, energy,...
