Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

The scientists showed that there are a number of organic molecules from diverse sources present in modern concrete structures and asphalt pavements: phthalates, diesel exhaust particulates, surfactants, and windshield washer fluids. Organic matter in water accelerates deterioration of asphalt pavements. Akihiro Moriyoshi, et al.

MIT team exploring using LOHCs directly on-board hydrogen-fueled trucks

Green Car Congress

—Prof Green To implement such a design, the team aims to modify the truck’s powertrain to allow onboard hydrogen release from the LOHCs, using waste heat from the engine exhaust to power the dehydrogenation process. —Sayandeep Biswas, first author Resources Sayandeep Biswas, Kariana Moreno Sader, and William H. 3c01919

Researchers developing free-piston linear generator for exhaust waste heat recovery

Green Car Congress

Researchers in China have developed a novel free-piston linear generator (FPLG) to recover exhaust waste heat efficiently from a vehicle engine. Therefore, it is necessary to recover exhaust energy of vehicle engine, and many strategies and methods have been adopted to reduce the energy waste and improve the fuel utilization efficiency.

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

However, both measurements also act as proxies for the complex mixture of gases in diesel exhaust, which is an established carcinogen and associated with respiratory, cardiovascular and reproductive health effects. Studies have linked both BC and UFP to detrimental health effects, although evidence is still emerging and not conclusive.

Study estimates the composition of non-exhaust atmospheric particulate matter from traffic

Green Car Congress

A study by a team of researchers in the UK has estimated the contributions of brake dust, tire dust, and resuspended dust to non-exhaust traffic particles as. As a result, these non-exhaust emissions make up a similar proportion of the airborne particulate matter (PM) resulting from vehicle use as exhaust emissions.

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

The research by the University of Edinburgh measured the impact of diesel exhaust fumes on healthy volunteers at levels that would be found in heavily polluted cities. The scientists had earlier shown that exposure to nitrogen dioxide, at levels in excess of those found in the present study, does not alter vascular function.

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.
