13 p, 1.2 MB Influence of synthesis conditions on the formation of a Kaolinitemethanol complex and simulation of its vibrational spectra / Matusik, Jakub (University of Science and Technology. Department of Mineralogy, Petrography and Geochemistry) ; Scholtzová, Eva (Slovak Academy of Sciences. Institute of Inorganic Chemistry) ; Tunega, Daniel (Universität für Bodenkultur. Institut für Bodenforschung)
Kaolinite is often used as a base for the synthesis of new organo-mineral nanomaterials designed for applications in industry and in environmental protection. To make the mineral structure more likely to interact with organic molecules, a kaolinite-methanol complex (KM) can be used. [...]

7 p, 185.6 KB La immigració com a lloc de memòria nacional / Cardús i Ros, Salvador, 1954- (Universitat Autònoma de Barcelona)
L'article parteix d'una paradoxa: tot i que la immigració ha estat la condició necessària per a la consolidació de la personalitat i força de Catalunya com a país, hom tendeix a invisibilitzar-la i, fins i tot, a percebre-la com una amenaça per a la identitat nacional. [...]
The article is based on a paradox: even though immigration has been the necessary condition for consolidating the personality and strength of Catalonia as a country, there is a tendency to make it invisible, to perceive it as a threat to the national identity. [...]
