At this scale, their properties change significantly compared with conventional materials, offering new applications in multiple scientific and technological fields.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p>These differences are mainly due to:<\/p>\n\n\n\n<p>\ud83d\udd39  The increase in surface effects, resulting from a higher ratio between surface atoms and volume.<br>\ud83d\udd39 Their high reactivity and adaptability, which depend both on the size and the shape of the nanoparticle.<br>\ud83d\udd39 Their multifunctionality, which opens up new possibilities in areas such as environmental remediation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use of nanomaterials in environmental remediation<\/h3>\n\n\n\n<p>Environmental engineering is actively incorporating nanotechnology to develop innovative solutions. In our group, we investigate:<\/p>\n\n\n\n<p>\u2714 Nanoparticles for water treatment, to reduce metals, nutrients and pesticides.<br>\u2714 Nanoparticles for the mitigation of greenhouse gases (CH\u2084 and N\u2082O) in air.<br>\u2714 Iron nanoparticles to optimize anaerobic digestion, significantly increasing biogas production when added under controlled conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Nanomaterials and chemical catalysis for a sustainable future<\/h3>\n\n\n\n<p>Nanomaterials have enormous potential to improve chemical processes and make them more efficient, especially in the field of chemical catalysis. In our research group, we focus on the development of new nanomaterials capable of optimising reactions of interest in the energy sector.<\/p>\n\n\n\n<p>We work along two main lines:<\/p>\n\n\n\n<p>\u26a1 Conversion of carbon dioxide (CO\u2082) to methanol: a sustainable alternative for the production of fuels and chemicals.<br>\u26a1 Conversion of carbon dioxide (CO\u2082) to methane: a key strategy for carbon capture and reuse.<\/p>\n\n\n\n<p>These studies contribute to the reduction of CO\u2082 emissions and to the development of more sustainable energy sources.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Nanotoxicology: the environmental impact of nanomaterials<\/h3>\n\n\n\n<p>Despite their potential, the environmental impact of nanomaterials is not yet fully understood. For this reason, we work on assessing their toxicity using methodologies such as:<\/p>\n\n\n\n<p>\ud83d\udd2cSeed germination tests.<br>\ud83d\udd2cBioassays with bioluminescent bacteria.<br>\ud83d\udd2cAerobic respirometry.<br>\ud83d\udd2cAnaerobic digestion tests.<\/p>\n\n\n\n<p>These research lines allow us to deepen our understanding of nanomaterials and to develop safer and more efficient environmental solutions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nanomaterials are defined as materials with at least one dimension smaller than 100 nanometres (nm), while nanoparticles are structures whose dimensions are all below this threshold.
