Els nanomaterials es defineixen com aquells materials amb almenys una dimensi\u00f3 inferior als 100 nan\u00f2metres (nm), mentre que les nanopart\u00edcules s\u00f3n estructures amb totes les seves dimensions per sota d\u2019aquest llindar. A aquesta escala, les seves propietats canvien significativament respecte als materials convencionals, oferint noves aplicacions en m\u00faltiples camps cient\u00edfics i tecnol\u00f2gics.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Aquestes difer\u00e8ncies es deuen principalment a:
\u2714 L\u2019increment dels efectes de superf\u00edcie, per una major relaci\u00f3 entre els \u00e0toms superficials i el volum.
\u2714 L\u2019alta reactivitat i adaptabilitat, depenent tant de la mida com de la forma de la nanopart\u00edcula.
\u2714 La seva multifuncionalitat, que obre noves possibilitats en \u00e0mbits com la remediaci\u00f3 ambiental.<\/p>\n\n\n\n

\u00das dels nanomaterials en la recuperaci\u00f3 ambiental<\/strong><\/h2>\n\n\n\n

L\u2019enginyeria ambiental est\u00e0 incorporant activament la nanotecnologia per desenvolupar solucions innovadores. Al nostre grup, investiguem:<\/p>\n\n\n\n

\u2714 Nanopart\u00edcules per al tractament d\u2019aigua, per reduir metalls, nutrients i pesticides.
\u2714 Nanopart\u00edcules per a la mitigaci\u00f3 de gasos d\u2019efecte hivernacle (CH\u2084 i N\u2082O) en l\u2019aire.
\u2714 Nanopart\u00edcules de ferro per optimitzar la digesti\u00f3 anaer\u00f2bia, incrementant significativament la producci\u00f3 de biog\u00e0s quan s\u2019afegeixen en condicions controlades.<\/p>\n\n\n\n

Nanomaterials i cat\u00e0lisi qu\u00edmica per a un futur sostenible<\/h2>\n\n\n\n

Els nanomaterials tenen un enorme potencial per millorar processos qu\u00edmics i fer-los m\u00e9s eficients, especialment en el camp de la cat\u00e0lisi qu\u00edmica. Al nostre grup de recerca, ens centrem en el desenvolupament de nous nanomaterials capa\u00e7os d\u2019optimitzar reaccions d\u2019inter\u00e8s en el sector energ\u00e8tic.<\/p>\n\n\n\n

Treballem en dues l\u00ednies principals:<\/p>\n\n\n\n

\u26a1 Conversi\u00f3 de di\u00f2xid de carboni (CO\u2082) a metanol: una alternativa sostenible per a la producci\u00f3 de combustibles i productes qu\u00edmics.
\u26a1 Conversi\u00f3 de di\u00f2xid de carboni (CO\u2082) a met\u00e0: una estrat\u00e8gia clau per a la captura i reutilitzaci\u00f3 del carboni.<\/p>\n\n\n\n

Aquestes investigacions contribueixen a la reducci\u00f3 d\u2019emissions de CO\u2082 i al desenvolupament de fonts d\u2019energia m\u00e9s sostenibles.<\/p>\n\n\n\n

Nanotoxicologia: l\u2019impacte ambiental dels nanomaterials<\/strong><\/h2>\n\n\n\n

Malgrat el seu potencial, l\u2019impacte ambiental dels nanomaterials no est\u00e0 encara del tot determinat. Per aix\u00f2, treballem en l\u2019avaluaci\u00f3 de la seva toxicitat, mitjan\u00e7ant metodologies com:
\ud83d\udd2c Proves de germinaci\u00f3 de llavors.
\ud83d\udd2c Assajos amb bacteris bioluminescents.
\ud83d\udd2c Respirometria aer\u00f2bia.
\ud83d\udd2c Proves de digesti\u00f3 anaer\u00f2bia.<\/p>\n\n\n\n

Aquestes l\u00ednies de recerca ens permeten aprofundir en el coneixement dels nanomaterials i desenvolupar solucions ambientals m\u00e9s segures i eficients.<\/p>\n\n\n\n
