Clara Inés Alcolado Olivares, PhD Student in Physical Chemistry at the University of Castilla-La Mancha in Spain. Studied the degree in Chemistry, University of Castilla-La Mancha, 2017-2021, Master’s Degree in Chemistry, University of Castilla-La Mancha, 2021-2022, Master's Degree in Secondary Teacher Training, University of Castilla-La Mancha, 2022-2023. I have a Membership since 2021 of Real Sociedad Española de Química. My research topic is on the field of Physical Organic Chemistry, my thesis is about the reactivity of peroxynitrite with organic compounds such as commonly used drugs, food preservatives, or components of atmospheric aerosols. The possible toxicity of the reagents used in these reactions would be reduced thanks to supramolecular chemistry. I use a Stopped Flow system, which allows me to measure absorbance and/or fluorescence of organic molecules.
