    Hacia el desarrollo de alternativas sostenibles al combustible diésel: síntesis de 1,1-dimetoximetano (OME1) a través de catálisis bifuncional
    (Pontificia Universidad Católica del Perú, 2023-06-14) Herrera, Jose Efrain; Rodriguez, Andrés F.
    The environmental impact generated by the extensive utilization of fossil-based fuels has driven the need to develop renewable energy sources, as well as sustainable processes for liquid fuels production. Oxymethylene ethers (OMEs) are oxygenated compounds that have emerged as a potential alternative to replace Diesel fuel, helping to reduce the formation of soot and nitrogen oxides (NOx) during its combustion. Among this family of compounds, 1,1-dimethoxymethane (OME1) has special interest because of its versatility as an industrial solvent or as a chemical intermediate. Specifically, it can be used as a feedstock to produce higher chain OMEs. The direct synthesis of OME1 involves the selective oxidation of methanol over bifunctional catalysts, which have been widely studied during the last decades. This work summarizes the main features of the different catalytic systems developed, which play a fundamental role for the commercial production of 1,1-dimethoxymethane

    Química bioortogonal: cuando los organismos vivos se convierten en matraces de reacción
    (Pontificia Universidad Católica del Perú, 2023-04-24) Idiago-López, Javier; De la Fuente, Jesus M.; Fratila, Raluca Maria
    In this article, we introduce the concepts of click chemistry and bioorthogonal chemistry, which have received the Nobel Prize in Chemistry 2022 for their numerous advantages (simplicity, robustness, practically quantitative yields, etc.). We describe the main bioorthogonal reactions that can be carried out in living systems, such as cells and even animals, which become exotic "reaction flasks". We also provide an overview of the latest advances in bionanomedicine, which were made possible by the combination of bioorthogonal chemistry with the unique properties of nanomaterials. To this end, the main characteristics of nanomaterials are presented, and some recent studies related to the development of new imaging and therapeutic tools are described.
