Online gas and aerosol measurement of water soluble carboxylic acids in Zurich [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2006
We discuss the diurnal and seasonal variability of low molecular weight organic acids in Zurich city on the basis of online quasi‐continuous measurement in the gas and aerosol phase using a wet effluent diffusion denuder/aerosol collector (WEDD/AC) coupled to ion chromatography.

Turbulent Drag Reduction with an Ultra-High-Molecular-Weight Water-Soluble Polymer in Slick-Water Hydrofracking

open access: yesMolecules, 2022
Water-soluble polymers as drag reducers have been widely utilized in slick-water for fracturing shale oil and gas reservoirs. However, the low viscosity characteristics, high operating costs, and freshwater consumption of conventional friction reducers ...

Carbon isotopic composition of water-soluble gases and their geological significance in the Sichuan Basin

open access: yesPetroleum Exploration and Development, 2012
Twenty-two gas and twenty-two water samples were collected from producing wells in the Triassic Xujiahe, Leikoupo and Jialinjiang formations and the Permian Maokou Formation in the Mid, South and Northwest Sichuan gas areas.

Structure elucidation of the water-soluble organic carbon fraction in atmospheric aerosols by mass spectrometry [PDF]

open access: yes, 2006
Atmospheric aerosols can act as cloud condensation nuclei (CCN) and scatter or absorb light thus influencing many important processes in the atmosphere.

Water deficit modifies the carbon isotopic composition of lipids, soluble sugars and leaves of Copaifera langsdorffii Desf. (Fabaceae)

open access: yesActa Botânica Brasílica, 2017
Water deficit is most frequent in forest physiognomies subjected to climate change. As a consequence, several tree species alter tissue water potential, gas exchange and production of carbon compounds to overcome damage caused by water deficiency.

Impact of drought stress on water potential and gas exchange parameters in Macedonian oak (Quercus trojana P.B. Webb.) seedlings

open access: yesTurkish Journal of Forestry, 2021
The increase in the duration and severity of summer droughts due to global climate change will adversely affect forests, and it is very important to examine the drought stress that trees are exposed to as a species due to increasing drought and to ...
