CdSe quantum dot-decorated double walled carbon nanotubes: the effect of chemical moieties
(2008-08)"We report that fluorine atoms on the outer tubes of double walled carbon nanotubes (DWNTs) are more effective for nucleating and growing CdSe nanoparticles than oxygen-containing functional groups. The CdSe particles with ... -
Cellular automata modeling of continuous stirred tank reactors
(2008)"The classical dynamical systems model of continuous stirred tank reactors (CSTR) in which a first order chemical reaction takes place is reformulated in terms of stochastic cellular automata by extending previous works of ... -
Cement pastes and mortars containing nitrogen-doped and oxygen-functionalized multiwalled carbon nanotubes
(Hindawi, 2016)"Cement pastes and mortars based on ordinary Portland cement containing nitrogen-doped multiwalled carbon nanotubes (MWCNT-Nx) or oxygen-functionalized multiwalled carbon nanotubes (MWCNT-Ox) are investigated. To incorporate ... -
Cerium-doped β-Ni(OH)2 hexagon nanosheets: an effective photocatalyst for the degradation of the emerging water pollutant, naproxen
(2018)"Nickel hydroxide β–Ni(OH)2 hexagonal nanosheets were synthetized via a hydrothermal exfoliation process. The practical microwave-assisted hydrothermal method facilitated obtaining layered nickel 3D nanoplates with cerium ... -
Chaotic dynamics of a nonlinear electronic converter
(2008)"The nonlinear electronic converter used by Rulkov and collaborators [Rulkov et al., 2001], which is the core of their chaotic oscillator, is modeled and simulated numerically by means of an appropriate direct relationship ... -
Characterization of the kinetic arrest of martensitic transformation in Ni45Co5Mn36.8In13.2 melt-spun ribbons
(Elsevier, 2018)"The kinetic arrest (KA) of martensitic transformation (MT) observed in Ni45Co5Mn36.8In13.2 melt-spun ribbons has been studied. These alloy ribbons show an ordered columnar-like grain microstructure with the longer grain ... -
Chemical stability of superhard rhenium diboride at oxygen and moisture ambient environmental conditions prepared by mechanical milling
(The American Ceramic Society, 2018)"In this study, rhenium diboride (ReB2) was obtained by mechanosynthesis at 640 minutes of milling. The obtained ReB2 was stored at oxygen and moisture ambient environmental conditions to know the chemical stability. The ... -
Classical harmonic oscillator with Dirac-like parameters and possible applications
(2004)"We obtain a class of parametric oscillation modes that we call K-modes with damping and absorption that are connected to the classical harmonic oscillator modes through the “supersymmetric” one-dimensional matrix procedure ... -
Cobalt double-ring and double-dot structures: Magnetic properties
(2016)"The magnetization reversal mechanism of nanostructures of cobalt double-rings (D-rings) and double-dots (D-dots) is investigated in the framework of micromagnetic simulations. The arrays contain two identical coupled rings ... -
Coexistence of two-photon absorption and saturable absorption in ion-implanted platinum nanoparticles in silica plates
(Optical Society of America, 2018)"Platinum nanoparticles were nucleated in a high-purity silica matrix by an ion-implantation method. The third-order nonlinear optical response of the samples was studied using femtosecond pulses at 800 nm with the z-scan ... -
Comment on demystifying the constancy of the Ermakov-Lewis invariant for a time-dependent oscillator
(World Scientific Publishing Company, 2018)"We show that a simple modification of the Lagrangian proposed by Padmanabhan in the paper [Mod. Phys. Lett. A33, 1830005 (2018)] leads to the most general dynamical invariant in [Ray and Reid, Phys. Lett. A71, 317 (1979)]." -
Comparison of two synthesis methods on the preparation of Fe, N-Co-doped TiO2 materials for degradation of pharmaceutical compounds under visible light
(Elsevier, 2017)"In this work, we report the synthesis, characterization and photocatalytic evaluation of visible light active iron-nitrogen co-doped titanium dioxide (Fe3+-TiO2?xNx) nanostructured catalyst. Fe3+-TiO2?xNx was synthesized ... -
Competing magnetic structures and magnetic transitions in Er(2)Ni(2)Pb: powder neutron diffraction measurements
(2008-07)"We have studied the magnetic structures of Er(2)Ni(2)Pb using a powder neutron diffraction technique in zero field. Previous bulk measurements suggested three distinct magnetic phase transitions. Our neutron diffraction ... -
