Journal ArticleDOI
Growth morphology and spectroscopy of multiwall carbon nanotubes synthesized by pyrolysis of iron phthalocyanine.
TL;DR: Preliminary spectroscopic measurements performed on these MWCNTs, show the unoccupied density of states has several resonances close to Fermi level, related both to the graphene electronic structure and the formation of the tube.
Journal ArticleDOI
Phase Separation of Dirac Electrons in Topological Insulators at the Spatial Limit

TL;DR: This work presents unique signatures manifested by the local electronic properties of the topological surface state in Bi2Te3 nanostructures as the spatial limit is approached, and shows a new approach to tune the Dirac point together with reduction of electronic disorder in topological insulator (TI) nanostructure systems.
Journal ArticleDOI
Gold nanoparticles grown inside carbon nanotubes: synthesis and electrical transport measurements
Rodrigo Segura,Claudia Contreras,Ricardo Henríquez,Patricio Häberle,J.J.S. Acuña,Alvaro Adrian,Pedro Alvarez,Samuel A. Hevia +7 more
TL;DR: Although the sensitivity of these hybrid nanostructures is rather low compared to alternative sensing elements, their response is remarkably fast under changing gas atmospheres, and their conductance was measured as a function of temperature.
Journal ArticleDOI
Phytostimulant properties of highly stable silver nanoparticles obtained with saponin extract from Chenopodium quinoa
Rodrigo Segura,Gustavo Vásquez,Emmanuel Colson,Pascal Gerbaux,Caroline Frischmon,Aleksandra Nesic,Aleksandra Nesic,Danni E García,Gustavo Cabrera-Barjas +8 more
TL;DR: Silver nanoparticles obtained by a so-called 'green' method could be considered as good candidates for application in the agricultural sector for seed treatment, or as foliar sprays and plant-growth-promoters.
Journal ArticleDOI
Selective growth of palladium and titanium dioxide nanostructures inside carbon nanotube membranes
Samuel A. Hevia,Pia Homm,Andrea Cortes,Verónica Núñez,Claudia Contreras,Jenniffer Vera,Jenniffer Vera,Rodrigo Segura +7 more
TL;DR: The synthesis of palladium and titanium dioxide nanostructures selectively inside carbon nanotubes is performed using these CNT-AAO membranes as nanoreactors.
