Measuring the thermal resistance of vertical interfaces separating two different media using infrared thermography
(Elsevier, 2019)
We propose a method to measure the thermal contact resistance at the vertical interface between two materials using lock-in infrared thermography with laser spot heating. We found an analytical expression for the surface ...
Amide-Directed Intramolecular Co(III)-Catalyzed C-H Hydroarylation of Alkenes for the Synthesis of Dihydrobenzofurans with a Quaternary Center
(American Chemical Society, 2020-07-17)
The first example of Cp*Co(III)-catalyzed intramolecular hydroarylation of allyl aryl ethers using an amide directing group for the preparation of 3,3-disubstituted dihydrobenzofurans in high yields is described. The ...
Identificación de atracciones urbanas centrales mediante seguimiento GPS y análisis de redes
(Asociación Española de Geografía, 2020-02-10)
[ES]Este estudio presenta una metodología aplicable en la identificación de atracciones turísticas centrales en entornos urbanos mediante el uso combinado de datos GPS y análisis de redes de atracciones visitadas por los ...
Magnetocaloric properties and unconventional critical behavior in (Gd,Tb)6(Fe,Mn)Bi2 intermetallics
(Elsevier, 2020-06-17)
The magnetic and magnetocaloric properties of the intermetallic family (Gd,Tb)6(Fe,Mn)Bi2 have been studied from 2 K to temperatures above the respective Curie temperatures TC. The substitution of Gd by Tb (Gd6FeBi2, ...
Comprehensive study of the magnetic phase transitions in Tb3Co combining thermal, magnetic and neutron diffraction measurements
(Elsevier, 2019-05-22)
A comprehensive study of the magnetic phase transitions in Tb3Co has been undertaken combining different techniques. Using single crystal neutron diffraction in the paramagnetic state a weak crystal structure distortion ...
Fast sizing of the width of infinite vertical cracks using constant velocity Flying-Spot thermography
(Elsevier, 2019-03-19)
Constant Velocity Flying-Spot thermography consists in scanning the sample surface by a focused CW-laser spot moving at constant speed. This technique was designed to study large surfaces in short times. In this work, we ...
Sizing the length of surface breaking cracks using vibrothermography
(Elsevier, 2020-03-16)
Ultrasound excited thermography is used to determine the length of vertical surface breaking cracks. Two methods are proposed based on the analysis of the maximum temperature reached along the line containing the crack and ...
Characterizing the shape and heat production of open vertical cracks in burst vibrothermography experiments
(Elsevier, 2019)
We present a quantitative characterization of the heat flux distribution generated at open vertical cracks in burstvibrothermography experiments. We use a stabilized inversion algorithm that is able to retrieve both ...
