The validity of n-alkanes to estimate intake and digestibility in Nellore beef cattle fed a tropical grass (Brachiaria brizantha cv. Marandu)
(Elsevier B.V., 2011-02-01)
The objective of the present experiment was to evaluate the ability of n-alkanes to estimate dry matter (DM) intake (DMI) and digestibility (DMD) in Nellore beef cattle fed a tropical grass cut at two growth stages (30 or ...
Foliar cuticular alkanes of Camarea (Malpighiaceae) and their taxonomic significance
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Camarea is a South-American endemic genus comprising eight species. In the present work n-alkanes from foliar cuticular waxes of 23 specimens, representing seven species of Camarea were analyzed, aiming at establishing ...
Comparison of the n-Alkanes and Polycyclic Aromatic Hydrocarbons Concentrations in the Atmosphere during the Preparation of Warm and Hot Mixtures Asphalt for Pavements
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
Asphalt binder is used in the production of hot mixes asphalt (HMA) for paving and, due to the high temperatures used, generates fumes thatcontainn-alkanes and polycyclic aromatic hydrocarbons (PAH). Asphalt mixes prepared ...

Wetting properties of n-alkane thin films to understand the adherence mechanism of artificial membranes on silicon substrates
In this work we present a study of the wetting properties of silicon samples coated with a single layer of n-alkane molecules that self-assemble perpendicular to the surface.The types of molecules studied here are n-alkane ...
Corrigendum to “Experimental and Nitta–Chao model prediction of high pressure density of p-xylene with dialkyl carbonates or n-alkanes"
(Academic Press Ltd - Elsevier Science Ltd, 2015-10)
It has come to our attention that in our paper published in The Journal of Chemical Thermodynamics (J. Chem. Thermodyn. 69 (2014) 193-?200), the density values for the composition x1 = 0.8031 of (n-octane (1) + p-xylene ...
