  Trends in Technical & Scientific Research Abstract The Intergovernmental Panel on Climate Change (IPCC) issued a challenge to the international community to achieve even greater reductions in carbon emissions than was previously believed desirable with its report on October 08, 2018. This will require a fundamental reevaluation of our current perspectives regarding a comprehensive energy strategy, given that economic growth is closely allied with energy use. World energy demand is likely to continue to increase, especially among those countries with an expanding population and/or expectations for higher standards of living. Thus, the task for policy-makers is to create an environment allowing power-generating methods to flourish, thereby establishing a stable, efficient, cost effective foundation of all available low-carbon sources of power production in supporting an expanding national economy. This commentary highlights a few of the challenges, benefits, and ri...

  Trends in Technical & Scientific Research Abstract Exposure scientists often use gas chromatography-mass spectrometry (GC-MS) systems for analysis of hazardous chemicals [1-3]. Because GC-MS systems with transmission quadrupole mass spectrometers transmission quadrupole mass spectrometers (TQMS) historically have limited portability, small ion trap mass spectrometers (ITMS) have been manufactured to reduce size and increase ruggedness of GC-MS systems [2, 4-8]. The formation of pseudomolecular ions observed in ITMS spectra are seen as a drawback, potentially leading to chemical misidentification [9]. It is proposed here that these spectral complexities can improve analytical power if the pseudomolecular ions can be used to differentiate chemical isomers, not possible with TQMS. Isomers of propyl and butyl sulfide were analyzed using TQMS and ITMS. TQMS spectra exhibited nearly identical peaks for sulfide isomers. ITMS yielded complex spectra with protonated molec...
