Designed and optimized a one-step minimal solution laser-supported process for the realization of single atom catalysts with different metal active sites (Cu, Co, and Fe). Employed the materials as working electrodes on electrochemical sensors for the detection of oxidative stress related biomarkers. Obtained hands-on experience on electrochemical testing with a potentiostat and PalmSens software. Published two research articles in Small Science and American Chemical Society Applied Nanomaterials.

Synthesized and characterized MoS2 and WSe2 2D nanomaterials through chemical vapor deposition. Obtained hands-on experience on the different parameters influencing the chemical vapor deposition synthesis of 2D nanomaterials.

Determined and optimized a mix of green solvents and additives to facilitate the scaling up of semitransparent solution processed organic solar cells via blade coating and printing methods. Managed databases containing solubility and physical attributes of different substances through the Hansen Solubility Parameters in Practice software (HSPiP). Mastered the employment of a blade coater equipment for the processing of thin films. Published a research article and a review article in Nature Energy and Frontiers in Electronics, respectively.

Tested the photocatalytic activity of TiO2 nanotubes through reactive oxygen species production for the degradation of organic contaminants and antimicrobial growth inhibition.

Demonstrated the enhancement of the antibacterial properties of graphene oxide when coupling it with silver and ceria nanoparticles. Obtained experience on microbiology by testing the materials’ antibacterial activity against gram-positive and gram-negative bacteria through counting of forming units analysis. Published a research article reporting the findings of the investigation in Royal Society of Chemistry Advances.

Imparted chemistry courses (hands-on at the lab) for children from low-income families.

Developed a heat-control glass by coating it with silver, tin oxide, aluminum oxide and titanium dioxide nanoparticles to be applied as a cost-effective technology to reduce air conditioning energy consumption in buildings. Developed a simulated business project to accompany the scientific findings.
