Porous graphene and graphenylene nanotubes: Electronic structure and strain effects
(2017-12-01)
The unusual and unique mechanical and electronic properties of nanostructured carbon materials make them useful in the construction of nanodevices. We investigate a new class of structures, called porous nanotubes, which ...
Carbon nanotube plasma functionalization: The role of carbon nanotube/maleic anhydride solid premix
(2019-10-15)
Carbon nanotubes (CNT) were functionalized by radio-frequency plasma using maleic anhydride (MA) as a source of functional groups. The MA insertion was performed in the solid form through a mixture with CNT conducted under ...
Single- and double-wall carbon nanotubes fully covered with tetraphenylporphyrins: Stability and optoelectronic properties from ab initio calculations
(Elsevier, 2015-06)
The optoelectronic properties of single- and double-wall carbon nanotubes (CNTs) noncovalently functionalized with tetraphenylporphyrins (TPPs) are addressed by dispersion-corrected ab initio calculations. Five CNT species ...
Highly Enhanced Vapor Sensing of Multiwalled Carbon Nanotube Network Sensors by n-Butylamine Functionalization
(Hindawi Publishing Corporation, 2014-08)
The sensing of volatile organic compounds by multiwall carbon nanotube networks of randomly entangled pristine nanotubes or the nanotubes functionalized by n-butylamine, which were deposited on polyurethane supporting ...
Amine functionalization of carbon nanotubes with solid urea using different plasma treatments
(2022-05-01)
Carbon nanotubes (CNTs) were amine-functionalized through treatments in inductively coupled post-discharge, capacitively coupled micro spark and pulsed micro arc/glow discharge plasma regions, using urea in solid state as ...
Noncovalent functionalization of carbon nanotubes and graphene with tetraphenylporphyrins: stability and optical properties from ab initio calculations
(Journal of Materials Science, 2014-11)
The stability, electronic, and optical properties of single-walled carbon nanotubes (CNTs) and graphene non-covalently functionalized with free-base tetraphenylporphyrin (TPP) molecules is addressed by density functional ...
Campos elétricos transversais sobre nanotubos de carbono: um estudo de primeiros princípios
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2008-03-25)
In this Thesis we studied through first principles methods the effects of uniform transversal electric fields on the structural and electronic properties of carbon nanotubes. We study the formation of Si-doped carbon ...
Single-Wall Carbon Nanotubes Covalently Functionalized with Polylysine: Synthesis, Characterization and Analytical Applications for the Development of Electrochemical (Bio)Sensors
(Wiley VCH Verlag, 2014-05)
This work reports the synthesis of single-wall carbon nanotubes (SWCNT) covalently functionalized with polylysine (Plys) and the analytical performance of glassy carbon electrodes (GCE) modified with this material ...
Dispersing carbon nanotubes in phenolic resin using an aqueous solution
(2011-11-01)
The ability to control the carbon nanotube (CNT) dispersion in polymers is considered the key to most applications of nanotube/polymer composites. The carbon nanotube dispersion into water with different surfactants, as ...
