Pyrrolic nitrogendoped multiwall carbon nanotubes using ballmilled slagSiC mixtures as a catalyst by aerosol assisted chemical vapor deposition
(IOP Publishing, 2020)"We demonstrated that the ballmilled slagSiC mixture is an effective catalyst to grow pyrrolic nitrogendoped multiwall carbon nanotubes (NMWCNTs) by aerosol assisted chemical vapor deposition (AACVD) method. NMWCNTs ... 
Quantum Hamiltonians and prime numbers
(2003)"A short review of Schrödinger Hamiltonian for which the spectral problem has beenVrelated in the literature to the distribution of the prime numbers is presented here. WeVnotice a possible connection between prime numbers ... 
Quasiexactly solvable hyperbolic potential and its antiisospectral counterpart
(Elsevier, 2022)"We solve the eigenvalue spectra for two quasi exactly solvable (QES) Schrödinger problems defined by the potentials V (x; ? ,?) = 4? 2 cosh4(x) + V1(? , ?) cosh2(x) + ? (? ? 1) tanh2(x) and U(x; ? , ?) = ?4? 2 cos4(x) ? ... 
Radius evolution for bubbles with elastic shells
(Elsevier, 2021)"We present an analysis of an extended Rayleigh–Plesset (RP) equation for a three dimensional cell of microorganisms such as bacteria or viruses in some liquid, where the cell membrane in bacteria or the envelope (capsid) ... 
Raman spectroscopy study of heattreated and borondoped double wall carbon nanotubes
(200907)"We performed Raman spectroscopy experiments on undoped and borondoped double walled carbon nanotubes (DWNTs) that exhibit the "coalescence inducing mode" as these DWNTs are heat treated to temperatures between 1200 C and ... 
Ramanujan sums for signal processing of lowfrequency noise
(2002)"An aperiodic (lowfrequency) spectrum may originate from the error term in the mean value of an arithmetical function such as Mobius function or Mangoldt function, which are coding sequences for prime numbers. In the ... 
Reactividad y propiedades catalíticas de partículas subnanométricas de Pt y FePt: un estudio basado en la teoría de la funcional de la densidad
(201511)"Atomic clusters constitute a new phase of matter, being the bridge between atoms and bulk. These systems have generated considerable interest, triggering one extensive research due to the fact that their physical and ... 
Reconfigurable dynamical logic gate with linear core
(2013)"A dynamically reconfigurable linear core logic gate is a device that allows logical outputs dependent upon configurable parameters set within device. The device is comprised of three blocks: The first block receives at ... 
Recrystallization of a Ti45Ni5Cu coldworked shape memory alloy characterized by thermoelectric power and electrical properties
(2014)"The recrystallization of a coldworked shape memory alloy (SMA) without Rphase transition, i.e. the Ti45.0Ni5.0Cu (% at.), has been studied by thermoelectric power (TEP) technique and electrical resistivity change (Dρ) ... 
Recuperación mejorada de petróleo con DLimoneno diluido en salmuera
(05/02/2020)DLimonene, a compound consisting of terpenes in its dextrogyrous form, is used as a degreaser, hydrocarbon waste cleaner and as a sand oil separator. In this thesis, the use of this solvent is proposed as a chemical ... 
Refrigerant capacity of austenite in asquenched and annealed Ni51.1Mn31.2In17.7 melt spun ribbons
(201204)"The thermal dependence of the magnetic entropy change (Delta SM(T)) and refrigerant capacity (RC) of austenite in asquenched ribbons of chemical composition Ni51.1Mn31.2In17.7 produced by melt spinning at a high cooling ... 
Relation of the average interaction field with the coercive and interaction field distributions in First order reversal curve diagrams of nanowire arrays
(Nature Publishing Group, 2020)"Firstorder reversal curve diagrams, or FORC diagrams, have been studied to determine if the widths of their distributions along the interaction and coercivity axes can be related to the meanfield magnetization dependent ... 
Relativistic hyperbolic motion and its higher order kinematic quantities
(Sociedad Mexicana de Física, A.C., 2022)"We investigate the kinematics of the motion of an observer with constant proper acceleration (relativistic hyperbolic motion) in 1+1 and 1+3 dimensional Minkowski spacetimes. We provide explicit formulas for all the ... 
Relativistic Rotating Electromagnetic Fields
(Hindawi, 2020)"In this work, we consider axially symmetric stationary electromagnetic fields in the framework of special relativity. These fields have an angular momentum density in the reference frame at rest with respect to the axis ... 
Remoción de la aberración cromática lateral en imágenes de microscopía óptica de campo claro
