1. 1. Development of a multi-collector inductively coupled plasma massspectrometry method for measurement of stable sulphur isotope ratios in aerosol sulphate

   University essay from Uppsala universitet/Analytisk kemi

   Author : Katerina Rodiouchkina; [2018]
   Keywords : Sulphate aerosol; isotope ratio; sulphur isotope; δ34S and δ33S measurements; MC-ICP-MS; method development; inter-laboratory comparison;

   Abstract : Sulphur stable isotope ratios are useful tracers in geological and environmental studies. They can for example be used to trace the origin of atmospheric sulphate aerosols, because anthropogenic sulphate and natural sulphate have distinguishable δ34S-values (δ34S value of approximately +0 to +8 ‰ for anthropogenic and approximately +12 to +19 ‰ for natural).

3. 2. Probing for chiral discrimination of alanine adsorption and oxidation on TiO2 particles in connection to homochirality

   University essay from Uppsala universitet/Institutionen för kemi - BMC

   Author : Katerina Rodiouchkina; [2016]
   Keywords : ;

   Abstract : The adsorption of both chiral forms of alanine on TiO2 was studied and compared to see if TiO2 has a chiral preference. Both the L- and D-form of alanine was photo-oxidized on TiO2 by UVlight to evaluate if there is a difference in the oxidation rate. READ MORE
