Cores: um estudo sobre a estrutura da matéria
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de QuímicaQuímicaUTFPR, 2019-12-10)
We present a study on the structure of matter from the common colors observed in nature. From the observation that colors are usually associated only with phenomena of emission, absorption, or reflection of light and that ...
Quantum gauge boson propagators in the light front
(2004-12-14)
Gauge fields in the light front are traditionally addressed via, the employment of an algebraic condition n·A = 0 in the Lagrangian density, where Aμ is the gauge field (Abelian or non-Abelian) and nμ is the external, ...

Goethite (alpha-FeOOH) Nanorods as Suitable Antiferromagnetic Substrates
(AMER CHEMICAL SOC, 2011)
We propose goethite nanorods as suitable anti-ferromagnetic substrates. The great advantage of using these inorganic nanostructures as building blocks comes from the fact that it permits the design and fabrication of ...
Analysis of RRT, PRM and voronoi path planning algorithms to solve a modular maze using a two-DOF platform
(2022)
This paper analyzes three path planning techniques to solve a ball-maze system with a two-degree-of-freedom platform. The system’s objective focuses on the ball traveling a path from an initial point to a final point ...
Simulación de las propiedades energéticas, termodinámicas y espectroscópicas de moléculas nanoconfinadas
(Universidad Nacional de ColombiaConsejo Superior de Investigaciones Científicas (CSIC)Bogotá - Ciencias - Doctorado en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-07-01)
El desarrollo de modelos y metodologías destinadas a entender las peculiaridades de ciertas estructuras moleculares confinantes, como clatratos, endofullerenos y nanogotas, tiene consecuencias directas en el campo de las ...
Experimental evidence of enhanced ferroelectricity in Ca doped BiFeO3
(Elsevier B.V., 2014-04-15)
Calcium (Ca)-doped bismuth ferrite (BiFeO3) thin films prepared by using the polymeric precursor method (PPM) were characterized by X-ray diffraction (XRD), field emission gun scanning electron microscopy (FEG-SEM), ...
