Thermal properties of a solid through q-deformed algebra
(Elsevier, 2012-06-15)
Implementação de um método de análise de imagens para integração da intensidade de raios X espalhados em uma câmera de Debye-Scherrer
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2007-02-16)
In the present work was developed a method for digital image analysis to execute the integration of the x-ray intensity dispersed in a camera of Debye-Scherrer. A software for digital images analysis of the dispersal pattern ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(2001-11-01)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Distribution of Relaxation Times: Debye Length Distribution vs Electrode Polarization by a Cole-Cole Relaxation Model
Mobility, diffusivity and charge density in polyelectrolytes, are generally determined from electrochemical impedance spectroscopy following the electrode polarization analysis, in which at a given temperature the peaks ...
Aplicações da q-Álgebra em física da matéria condensada
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2014-04-25)
We address the generalization of thermodynamic quantity q-deformed by q-algebra that
describes a general algebra for bosons and fermions . The motivation for our study stems
from an interest to strengthen our initial ideas, ...
Mechanical and thermodynamical properties of β Cu Al Mn alloys along the Cu3Al → Cu2AlMn compositional line
(Pergamon-Elsevier Science Ltd, 2020-10)
The elastic properties of Cu − Al − Mn alloys with compositions along the Cu3Al → Cu2AlMn line and bcc-based structures, are studied by means of first-principles calculations. From the calculated elastic constants, the ...
DEBYE CHARACTERISTIC TEMPERATURE OF CUBIC SOLIDS

A Gas Sensor Based on a Single SnO Micro-Disk
(Mdpi, 2018-10-01)
In this study, individual nanofabricated SnO micro-disks, previously shown to exhibit exceptional sensitivity to NOx, are investigated to further our understanding of gas sensing mechanisms. The SnO disks presenting different ...
