Photocatalytic oxidation (PCO) air purification technology is reviewed based on the decades of research conducted by the United Technologies Research Center (UTRC) and their external colleagues. UTRC conducted basic research on the reaction rates of various volatile organic compounds (VOCs). The knowledge gained allowed validation of 1D and 3D prototype reactor models that guided further purifi...
Purification of single-walled carbon nanotubes (SWNTs) is still remaining a challenging task. The aim of this work is to show novel and fast concepts for the purification of CNTs by combination of different techniques and analyses the effect of that methods on the carbon nanotubes. The carbonaceous particles were presumably etched away by the selective oxidation with faster etching rate than na...
Overview In free-surface flows the turbulence in the liquid may be sufficient to disturb the surface to the point of entraining air into the flow. This process is important, for example, in water treatment where air is needed to sustain microorganisms for water purification and in rivers and streams for sustaining a healthy fish population. Air entrainment is typically engineered into spillways...
