Could titanium-clean air be how advertisers one day try to sell us the virtues of paint or even clothing that reduces the pollution caused by automobiles? The technology behind such products involves the well-known ability of titanium dioxide (TiO2) to photocatalytically split water to form hydroxyl and peroxyl radicals, a reaction that has already been harnessed to make self-cleaning windows. ...

The net impact of human nitrogen (N) fixation on climate (ignoring short-lived components) mainly depends on the magnitude of the warming effect of (direct and indirect) nitrous oxide (N2O) emissions and the cooling effect of N-induced carbon dioxide (CO2) uptake. N-induced CO2 uptake is caused by anthropogenic N deposition which increases net primary production (NPP) in N-limited ecosystems an...

The paper analyzes the cost-efficiency of trading CO2 emissions by focusing on the overall environmental impacts of active climate policy measures. When reducing CO2 emissions, other emissions, also related to the consumption of fossil fuels, decrease with no additional cost. These secondary benefits must be taken into consideration when analyzing gains from international emissions trading. The...

This study investigates the economic validity of the diffusion of fuel cell vehicles (FCVs) and all-electric vehicles (EVs), employing a cost-benefit analysis from the social point of view. This research assumes the amount of NOx and tank-to-wheel CO2 emissions and gasoline use reduction as the benefits and the purchase costs, infrastructure expenses, and maintenance costs of alternative vehicl...

The paper outlines the Emission and Biofuel Directives relating to CO2 emissions in cars and the fiscal penalties incurred by manufacturers failing to meet targets. The effect on emissions of the biofuel directives are quantified through a test programme which measures emissions from a turbo-charged diesel engine using a range of biodiesel fuels, using standard diesel fuel to obtain a compariso...

1. ABSTRACT: The US Military needs reliable, secure, and low-environmental impact sources of base and shore power for its installations. US Navy ships need generating systems for main propulsion, on-board power, catapults, heat/air conditioning, and other applications. These needs can be met with a unique, drive-gas generator that produces a high enthalpy mixture of high purity steam and carbon...
