abstract: â in this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. for this purpose, the tangent plane distance (tpd) minimization method was used. first, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. the results show that for a binary mixture of th...

background: hazardous chemicals, which give detrimental effect to the central nervous system, are widely used in the vehicle services industry. the use of vibrotactile perception threshold (vpt) as a screening tool for chemical exposure is new in developing country such as malaysia. therefore, this study determined the relationship between vpt and chemical exposure among vehicle service technic...

: Gasoline-ethanol-methanol (GEM) blends have been considered to replace pure gasoline for spark ignition engine fuel. Its physical and chemical properties as well performance emission measurements from real engines reported in the literature, but it lacks fundamental study that can explain unique results of GEM compared gasoline. This aims compare laminar burning velocity at different mixtures...

Natural gas is increasingly being viewed as one of the most viable alternatives to gasoline. However, its vehicular application will only be widespread if safe and high-capacity methane stores are developed. In this work, we report an over 33% increase in methane uptake on a post-synthetically modified metal–organic framework. The underlying mechanism for this dramatic increase is due to lattic...

This work was funded by the Hydrogen Program Office of the U.S. Department of Energy under Grant No. DE-FG01-99EE35099 and represents the second task of three to be completed under this contract. The first task presented a broad overview of the costs for creating infrastructures to supply direct hydrogen, methanol, and gasoline to support fuel cell vehicles (FCV’s). A conclusion of the report r...

Emissions from gasoline and diesel vehicles are predominant anthropogenic sources of reactive gas-phase organic carbon and key precursors to secondary organic aerosol (SOA) in urban areas. Their relative importance for aerosol formation is a controversial issue with implications for air quality control policy and public health. We characterize the chemical composition, mass distribution, and or...

Benzene is used as an additive into gasoline to increase octane rating and prevent engine knocking. Being a toxic air pollutant known to have carcinogenic effects, knowledge of its concentration can be of aid in the assessment of possible health hazards to persons handling and using gasoline. The U.S. Federal Clean Air Act and the European Community specifications mandate a level of benzene in ...
