9 p, 1.6 MB The Role of Temperature on the Degree of End-Closing and Filling of Single-Walled Carbon Nanotubes / Kierkowicz, Magdalena (Institut de Ciència de Materials de Barcelona) ; Pach, Elzbieta (Institut Català de Nanociència i Nanotecnologia) ; Fraile, Julio (Institut de Ciència de Materials de Barcelona) ; Domingo, Concepción (Institut de Ciència de Materials de Barcelona) ; Ballesteros, Belén (Institut Català de Nanociència i Nanotecnologia) ; Tobias, Gerard (Institut de Ciència de Materials de Barcelona)
Carbon nanotubes (CNTs), owing to their high surface area-to-volume ratio and hollow core, can be employed as hosts for adsorbed and/or encapsulated molecules. At high temperatures, the ends of CNTs close spontaneously, which is relevant for several applications, including catalysis, gas storage, and biomedical imaging and therapy. [...]

The desire to study biology in situ has been aided by many imaging techniques. Among these, X-ray fluorescence (XRF) mapping permits observation of elemental distributions in a multichannel manner. However, XRF imaging is underused, in part, because of the difficulty in interpreting maps without an underlying cellular 'blueprint'; this could be supplied using contrast agents. [...]
