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/water interface is key toward understanding hydrophobicity at the molecular level. Herein, we characterize the hydrogen-bonding network of interfacial water next to sub-micron-sized hydrophobic oil droplets ...

PoolDilutionR: An R package for easy optimization of isotope pool dilution calculations

Methods in Ecology and Evolution, 2023
Isotopic pool dilution is a powerful approach to quantify gross biogeochemical transformation rates, but remains seldom used despite its potential. To facilitate broader implementation of pool dilution methods, we present a user‐friendly R package that ...

¹³C Isotope Labelling to Follow the Flux of Photorespiratory Intermediates

Plants, 2021
Measuring the carbon flux through metabolic pathways in intact illuminated leaves remains challenging because of, e.g., isotopic dilution by endogenous metabolites, the impossibility to reach isotopic steady state, and the occurrence of multiple pools ...

Levels of Alternaria Toxins in Selected Food Commodities Including Green Coffee

Toxins, 2020
Alternaria toxins are emerging mycotoxins, candidates for regulation by European Authorities. Therefore, highly sensitive, confirmatory, and reliable analytical methodologies are required for their monitoring in food. In that context, an isotope dilution

Modelos matemáticos para o estudo do fluxo biológico do fósforo em suínos alimentados com dietas suplementadas com níveis crescentes de fitase Mathematical models for the study of the biological flow of phosphorus in pigs fed with diets containing increasing levels of phytase

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
A pesquisa foi realizada para avaliar o fluxo biológico do fósforo entre os compartimentos, fisiológicos ou anatômicos, de suínos mantidos em dietas que continham níveis crescentes de fitase, usando o P-32 como traçador.
