Water Structure at the Hydrophobic Nanodroplet Surface Revealed by Vibrational Sum Frequency Scattering Using Isotopic Dilution. [PDF]

J Phys Chem B, 2022
The water structure at the hydrophobic/waterinterface is key toward understanding hydrophobicity at themolecular level. Herein, we characterize the hydrogen-bondingnetwork of interfacial water next to sub-micron-sized hydrophobicoil droplets dispersed in

Vitamin A equivalency of ß-carotene in healthy adults: limitation of the extrinsic dual-isotope dilution technique to measure matrix effect [PDF]

, 2009
Data on the vitamin A equivalency of ß-carotene in food are inconsistent. We quantified the vitamin A equivalency (¿g) of ß-carotene in two diets using the dual-isotope dilution technique and the oral¿faecal balance technique.

Noble gases in the Cameroon line and the He, Ne, and Ar isotopic compositions of high mu (HIMU) mantle [PDF]

, 1999
Ultramafic xenoliths, basaltic lavas, and CO2 gases from the Cameroon line volcanic chain provide the first characterization of combined He, Ne, and Ar isotopes in a high-time-integrated 238U/204Pb = μ (HIMU) magmatic system. Helium isotopic compositions
