It all started in 1985, when Kroto, Smalley and Curl discovered by serendipity a new carbon allotrope. They synthesized for the first time the C60 molecule, and named it as ”Buckminsterfullerene”, because ...
Güell Serra, Mireia (Date of defense: 2009-07-30)
La presència de la química teòrica i computacional està augmentant en quasi tots els camps de la recerca en química. Els càlculs teòrics poden ajudar a entendre millor l'estructura, les propietats i la ...
Poater Teixidor, Albert (Date of defense: 2006-04-24)
Aquesta tesi és el reflex que de la cooperació entre grups experimentals i grups teòrics s'aconsegueix l'assoliment d'objectius inassolibles de forma individual. A partir de la DFT s'expliquen processos ...
