Reducing total sulfur in motor fuels has become a critical air pollution control goal worldwide. As countries mandate ever lower permissible levels of total sulfur in fuels, the environmental monitoring and fuel manufacturing industries have been forced to find more sensitive techniques for analysis. Gas chromatography coupled to inductively coupled plasma mass spectrometry (GC-ICP-MS) has the ...

In propellant systems, fuels of choice continue to be hydrazine and its derivatives, even though they comprise a class of acutely carcinogenic and toxic substances which exhibit rather high vapor pressures and require expensive handling procedures and costly safety precautions. Only recently (2008), ionic liquids (salts with melting points less than 100 °C) with the dicyanamide anion were shown...

Hybrid energy generation models based on a variety of alternative energy supply technologies are considered the best way to cope with the depletion of fossil energy resources and to limit global warming. One of the currently missing technologies is the mimic of natural photosynthesis to convert carbon dioxide and water into chemical fuel using sunlight. This idea has been around for decades, bu...

brain tissue. (2) Metabolic recovery pathways are fundamentally altered when lactate or hydroxybutyrate replaces glucose as the primary oxidative substrate. The implications of this study reach beyond enhancing our understanding of how the neonatal brain functions. While the observations that lactate can serve as a substrate for the neonatal brain confirms existing knowledge, the facts that it ...

The use of oxygenated fuels is anticipated to increase over the next decades. This paper reviews the toxicological and exposure information for methyl tertiary-butyl ether (MTBE), a fuel additive, and methanol, a replacement fuel, and discusses the possible health consequences of exposure of the general public to these compounds. For MTBE, the health effects information available is derived alm...
