UW Madison chemists discover new way to harness energy from ammonia

Green Car Congress

A research team at the University of Wisconsin–Madison has identified a new way to convert ammonia to nitrogen gas through a process that could be a step toward ammonia replacing carbon-based fuels. However, burning ammonia releases toxic nitrogen oxide gases. The new reaction avoids those toxic byproducts. Trenerry, M.J., Wallen, C.M.,

NIST Characterizes -valerolactone Blends in Gasoline and Diesel

Green Car Congress

The vapor pressure of this fluid is relatively low when compared with ethanol; thus the fluid, when mixed with gasoline, will result in lower VOC emissions in storage, since it serves as a “keeper”. Conversely to the effect on diesel fuel, the additive shifts the distillation curve of gasoline to higher temperatures.
