Experimental investigation of integrated systems for biohydrogen and biomethane production
… The bioH2 production is enhanced by CO2 and N2 sparging, resulting in a 40% and 35% increase, respectively, under improved conditions. The highest H2 efficiency of 92.5% is achieved using an aluminum plate while sparging CO2 gases at a rate of 400 mL/min. The peak productions of the …

Investigation of the Oxygen Isotope Exchange Between Carbon Dioxide and O3 via O(1D)
… d17O =1.7 d18O. This is contrary to tropospheric CO2 where d17O ~ 0.5d18O. These isotope enrichments are transferred from O3 into CO2, but details of the mechanism are not understood yet. A systematic study was carried out using O2 and CO2 gases of different isotopic composition. Results show the …

Thermodynamic and Thermochemical Investigation of Advanced Triso Coated Particle Fuels
… experimentation. Specifically, the mixing of CO/CO2 gases and the humidification of H2 or H2/Ar gas mixtures was evaluated. Experiments conducted as part of this effort utilized Ultra High Purity (UHP) Ar gas which was used to create an atmosphere with a very low oxygen pressure but without the …

Structure-property relationships from molecular simulation of polymeric matrix composites
… content fibers promoted formation of CO and CO2 gases which lowered the final fiber carbon content. Regardless of the initial molecular orientation of s-PAN, the carbonization process shifted the final graphitic structures toward a random orientation relative to the fiber axis. Higher …

A Quantification Analysis on Potential Use of Recuperated Regenerative Braking Energy from NYCT Subways into Charging Electric Buses
… a total of .27 pounds of carbon dioxide (CO2) gases per passenger mile. Even though on a per passenger-mile basis, emissions from single occupancy vehicles are up to five times higher than the per-passenger mile emissions of mass transit, MTA is making efforts to reduce this emission to …

The literature on perceptions of environmental taxation in South Africa
Environmental problems are all around us. Some of us acknowledge them; others pretend that they are not there. The reality is that if something is not done soon our planet may be destroyed. We tend to think that environmental problems are not our problem, that the government should sort them out. …
