Controlled growth of one-dimensional clusters of molybdenum atoms using double-walled carbon nanotube templating
(2009)"We report the controlled growth of one-dimensional clusters of molybdenum atoms inside the inner cores of double-walled carbon nanotubes. A combined characterization including high resolution transmission electron microscopy, ... -
Controlling chemical and physical properties of ordered carbon nanosystems
(2010-08)"Nanoscience and nanotechnology are dedicated to the creation of new materials with interesting properties like hardness, conductivity, magnetic properties, among others. Now, there is also interest in the use of these ... -
Cytotoxicity induced by carbon nanotubes in experimental malignant glioma
(Dove Press Ltd, 2017)"Despite multiple advances in the diagnosis of brain tumors, there is no effective treatment for glioblastoma. Multiwalled carbon nanotubes (MWCNTs), which were previously used as a diagnostic and drug delivery tool, have ... -

Diameter-selective separation of double-walled carbon nanotubes
(2008-12)"Here, we report a simple and effective way of separating double-walled carbon nanotubes as a function of their diameter using individually dispersed nanotube solutions with the aid of long and random single-stranded DNA. ... -
Metal decorated carbon nanotube aerogels from sodium polyacrylate crosslinking by divalent ions
(Elsevier, 2023)In this work sodium polyacrylate functionalized carbon nanotube aerogels were prepared from aqueous medium by simple ionic cross-linking using copper nitrate and calcium chloride as cation sources to obtain self-standing ... -
Pyrrolic nitrogen-doped multiwall carbon nanotubes using ball-milled slag-SiC mixtures as a catalyst by aerosol assisted chemical vapor deposition
(IOP Publishing, 2020)"We demonstrated that the ball-milled slag-SiC mixture is an effective catalyst to grow pyrrolic nitrogen-doped multiwall carbon nanotubes (N-MWCNTs) by aerosol assisted chemical vapor deposition (AACVD) method. N-MWCNTs ... -
Strong and stable photoluminescence from the semiconducting inner tubes within double walled carbon nanotubes
(2009-01)"We examined the optical features of single wall carbon nanotubes (SWNTs) and the inner tubes within double walled carbon nanotubes (DWNTs) having the same (n,m) chirality. The brighter and more stable photoluminescence ... -
Synthesis of nanocomposites from polyaniline, polypyrrole and carbon nanotubes, and unzipping of multi-walled carbon nanotubes for the obtention of new graphitic nanomaterials
(2010-08)"La síntesis de compositos a partir de nanotubos de carbono ha tenido como principal reto el lograr una buena dispersión de los primeros en la matriz polimérica y para ello se han utilizado diversos métodos de funcionalización. ... -
Trends in nanoscience, nanotechnology, and carbon nanotubes: a bibliometric approach
(2014)"Carbon nanotubes are currently one of the most important materials due to their strong mechanical resistance, light weight, and transport properties. Since the publication of Ijima’s paper on tubular carbon structures ... -
Understanding the electrochemistry of armchair graphene nanoribbons containing nitrogen and oxygen functional groups: DFT calculations
(Royal Society of Chemistry, 2020)"The surface and edge chemistry are vital points to assess a specific application of graphene and other carbon nanomaterials. Based on first-principles density functional theory, we investigate twenty-four chemical functional ...
