Wet and dry removal are taken into account as well as the conversion of sulphur dioxide to sulphate. In regions of Europe with heavy annual precipitation, such as southwest Norway, corrections to the deposition pattern are made. Other factors, such as the diurnal variation of mixing depth and ...
The minor peaks at 168.2–168.8 eV are due to the sulphate species formed by sulphur oxidation in air8. In addition, the N 1s spectra of EFG and EFG–S samples show the domination of pyrrolic-type N peak at 399.5–399.8 eV, which further confirms the chemical bonding between rGO and ...
25Mg, 27Al, and 33S spectra were referenced indirectly using external reference ammonium sulphate, respectively, standards in D2O. (δ = 0) MgCl2, Al(NO3)3, and saturated References 1. Aurbach, D. et al. Prototype systems for rechargeable magnesium batteries. Nature 407, 724–727 (...
The in-cloud conversion of SO 2 to sulphate is an important part of the modelling of sulphur dispersion. The description of this process requires a coupling to meteorological processes in particular clouds and precipitation. In this study, the description of bulk wet scavenging is coupled to ...
(FMQ) buffer and two log units above it (FMQ + 2), corresponding to a switch from sulphide(S2-)- to sulphate(SO42-)-dominated conditions33. The most sulphur-rich melt inclusion has a S concentration (5080 ppm) well exceeding the S solubility of a relatively reduced magma (around...
Since it could be expected from the biological oxidation in situ at the soil, that the conversion of elemental sulphur in the elemental stage to sulphate (reference is made to the above-mentioned chemical reaction type) would locally, in the micro environment of the μm S particle deposit, ...
The kinetics of the conversion of ammonia and sulphur dioxide to ammonium sulphate in water droplets in the atmosphere in the absence of metal ion catalysts has been reconsidered. It is concluded that the reaction is an order of magnitude faster than earlier work suggested, and that lowering the...
The formation of sulphate through liquid reaction between SO2 and ozone is small for the summer simulation where the hydrogen peroxide concentrations was chosen equal to 1 ppb, but important for the winter case with large-scale stratiform precipitation and hydrogen peroxide level of 0.25 ppb. The ...
(III), ferrous ammonium sulphate was added to reach a 1:1:2 CyaY/IscS/Fe molar ratio under aerobic conditions. The data were recorded using a 1 M PILATUS detector (DECTRIS) at a sample-detector distance of 2.7 m and a wavelength of 1.5 Å, covering the range of momentum transfer ...
coli has two different O-acetylserine (thiol)lyases, the O-acetylserine (thiol)lyase B (“CysM”) also being able to transfer thiosulphate to O-acetylserine. As a result, S-sulphocysteine is formed, which is then split into L-cysteine and sulphite or sulphate in a manner which has not ...
