El passat 19 de desembre el alumnes de BAT del cientificotecnol\u00f2gic van poder assistir \u00a0a la confer\u00e8ncia a c\u00e0rrec d\u2019en Xavier Rius Ferr\u00fas, catedr\u00e0tic i ex-deg\u00e0 de la facultat de qu\u00edmica de l\u2019URV, professor em\u00e8rit, a m\u00e9s de formar part del\u00a0Grup de Quimiometria, Qualimetria i Nanosensors, entre altres \u00a0excepcionals formacions i aptituds, sobre la nanoci\u00e8ncia i la nanotecnologia.<\/p>\n

Amb les seves explicacions hem pogut entendre com els dragonets poden v\u00e8ncer la For\u00e7a de la gravetat i com els vitralls de l\u2019\u00e8poca medieval prenien diferents tons de colors, sense haver addicionat cap colorant, mitjan\u00e7ant la fluoresc\u00e8ncia.
\nTot aix\u00f2 \u00e9s possible traslladant-nos als fen\u00f2mens que tenen lloc quan els materials tenen alguna dimensi\u00f3 espacial m\u00e9s petita de 100 milion\u00e8simes de mil\u00b7l\u00edmetre (100 nm). La interacci\u00f3 de la mat\u00e8ria d\u2019aquestes dimensions amb qualsevol forma de l\u2019energia t\u00e9 lloc de forma molt diferent als materials que anomenem macrosc\u00f2pics i amb els que interactuem normalment en la nostra vida di\u00e0ria. La gran superf\u00edcie respecte al seu volum, les forces electrost\u00e0tiques i els efectes qu\u00e0ntics, entre d\u2019altres, entren en joc en el m\u00f3n nano i donen lloc a propietats extraordin\u00e0ries. Aix\u00ed, per exemple, certes nanopart\u00edcules poden presentar fen\u00f2mens \u00f2ptics (per exemple fluoresc\u00e8ncia) que no presenten els materials m\u00e9s grans de la mateixa composici\u00f3 o els materials formats per nanotubs de carboni presenten una resist\u00e8ncia comparable a la de l\u2019acer per\u00f2 amb un pes molt redu\u00eft i una elasticitat molt m\u00e9s elevada.<\/p>\n

La confer\u00e8ncia ha sigut molt interessant i amena, els alumnes han participat activament per saber els per qu\u00e8s, incentivant l\u2019esperit cient\u00edfic. Una altra vegada m\u00e9s moltes gr\u00e0cies Xavier Rius per haver-nos visitat.<\/p>\n","protected":false},"excerpt":{"rendered":"
