Molecular distribution and compound-specific hydrogen isotopic ratios (δD) of n-alkanes in shallow-water surface sediments from the Chaka salt lake and from various terrestrial plants in the surround...
Molecular composition and compound-specific carbon and hydrogen stable isotope ratios of n-alkanes are presented for leaves of grass, reeds and trees from five regions extending between latitudes 22°...
Stable carbon (δ13C) and hydrogen (δD) isotopic compositions of n-alkanes in total suspended particles from Tokyo were measured to decipher their source and transport in the polluted urban atmosphere....
The primary sources and atmospheric chemistry of C2-C5 alkanes were incorporated into the atmospheric chemistry general circulation model EMAC. Model output is compared with new observations from the ...
Size-segregated (9 stages) n-alkanes, polycyclic aromatic hydrocarbons (PAHs) and hopanes in the urban (Baoji city in inland China), mountain (Mt. Tai in east coastal China) and marine (Okinawa Island...
Diesel fuels having poor ignition properties would induce problems such as diesel knock and engine starting problems in cold weather. Diesel fuels in such cases need to have improved ignition propert...
Total suspended particles samples inside and outside the South Pu-Tuo Temple (SPT), a traditional Buddhist temple in Xiamen, China were collected and further analyzed for n-alkanes and polycyclic ar...
The available database concerning rate constants for gas-phase reactions of the hydroxyl (OH) radical with alkanes through early 2003 is presented over the entire temperature range for which measureme...
Hydrogen isotope ratios were measured on terrigenous alkanes (n-C25 to n-C31) extracted from recent lake surface sediments from the climatically and environmentally distinct basins Qiangyong Glacier L...
C-H bond activation was studied by use of density functional theory (DFT) and ONIOM calculations as implemented in Gaussian 2003 at the B3LYP level utilising 6-31G* as the basis set for Si, Al, and Fe...
The objective of the study was to evaluate the use of n-alkanes to estimate DM intake and digestibility by beef cattle. Six steers were blocked (3 blocks, 2 animals/block) according to the body weight...
Assam crude oil long residue (370oC+) is highly waxy/aromatic in nature associated with high pour point (51oC). The solid alkane components of this fraction extracted through urea adduction were analy...
The paper presents a vapour liquid equilibria study in binary mixtures of n-alkanes with high dimensional asymmetry. Each mixture contains ethane and alkanes higher than eicosane. Calculations were do...
Volatiles formed on heating clay minerals contain a variety of cations and anions and are highly reactive. Gas chromatograph-mass spectrometer analysis of long-chain n-alkanes exposed to such volatile...
Lattice spacings of layer silicates, particularly clay minerals, may exceed 20 Å. The errors in measuring lattice spacings increase rapidly for spacings greater than about 10 Å and diffrac...
