Viscosity measurements of ortho-xylene, meta-xylene, para-xylene and ethylbenzene [PDF]
The Journal of Chemical Thermodynamics, 2016 Abstract The compressed liquid viscosities of ortho-xylene, meta-xylene, para-xylene and ethylbenzene were measured using a vibrating-wire viscometer at different temperatures and pressures. The measurements were performed over the temperature ranges of (273 to 373) K for o-xylene and m-xylene, (293 to 373) K for p-xylene and (253 to 373) K for ...

Emission characteristics of nonmethane hydrocarbons from private cars and taxis at different driving speeds in Hong Kong [PDF]
, 2011 Vehicular emissions are the major sources of a number of air pollutants including nonmethane hydrocarbons (NMHCs) in urban area. The emission composition and emission factors of NMHCs from vehicles are currently lacking in Hong Kong.

Characterization of volatile organic compounds at a roadside environment in Hong Kong: An investigation of influences after air pollution control strategies [PDF]
, 2015 Vehicular emission is one of the important anthropogenic pollution sources for volatile organic compounds (VOCs). Four characterization campaigns were conducted at a representative urban roadside environment in Hong Kong between May 2011 and February ...

Design and fabrication of chemically robust three-dimensional microfluidic valves [PDF]
, 2007 A current problem in microfluidics is that poly(dimethylsiloxane) (PDMS), used to fabricate many microfluidic devices, is not compatible with most organic solvents. Fluorinated compounds are more chemically robust than PDMS but, historically, it has been

Synthesis and Characterization of Nitro-p-xylenes
Molecules, 2005 In this paper we elected to nitrate p-xylene because this compound has onlyone mononitro- and trinitro- isomer. Trinitro-p-xylene was used as a starting material forthe synthesis of other compounds in subsequent work.

Enantioselective Total Synthesis of (–)-Myrifabral A and B [PDF]
, 2020 A catalytic enantioselective approach to the Myrioneuron alkaloids (−)-myrifabral A and (−)-myrifabral B is described. The synthesis was enabled by a palladium-catalyzed enantioselective allylic alkylation, that generates the C(10) all-carbon quaternary ...
