During my Master's thesis, I determined the presence of toxic and non-toxic trace elements in edible mushrooms from Southern Spain and Northern Morocco. I utilized Inductively Coupled Plasma Mass Spectrometry (ICP-MS) as the analytical technique for the analyses. To gain further insights, I applied data visualization, descriptive statistics, and clustering and PCA methods to recognize patterns within the data set. This helped in connecting the accumulation of trace elements to either external… Show more During my Master's thesis, I determined the presence of toxic and non-toxic trace elements in edible mushrooms from Southern Spain and Northern Morocco. I utilized Inductively Coupled Plasma Mass Spectrometry (ICP-MS) as the analytical technique for the analyses. To gain further insights, I applied data visualization, descriptive statistics, and clustering and PCA methods to recognize patterns within the data set. This helped in connecting the accumulation of trace elements to either external or intrinsic factors. These results also delivered key information on food safety, which is of significant value to businesses and consumers at the local and national levels. Show less

In my Final Degree Project, the impact of doping on "A" position of organic-inorganic hybrid perovskites was investigated. Using UV-Vis spectroscopy and X-ray diffraction, the samples were characterized. The study aimed to create stable hybrid perovskites with optimized band gap values for photovoltaics. The result showed that doping the A site with two or three cations produced perovskite nanopowders with enhanced structure and improved optical properties, with FA0.1MA0.9PbI3 and… Show more In my Final Degree Project, the impact of doping on "A" position of organic-inorganic hybrid perovskites was investigated.

The result showed that doping the A site with two or three cations produced perovskite nanopowders with enhanced structure and improved optical properties, with FA0.1MA0.9PbI3 and FA0.1Cs0.1MA0.8PbI3 having a stable cubic crystalline structure and band gap values of 1.48 eV and 1.47 eV respectively. In summary, A-site doping proved effective in synthesizing hybrid perovskite nanopowders with improved structure and optical properties. Show less
