Study of the magnetocaloric effect in intermetallics RTX (R = Nd, Gd; T = Sc, Ti ; X = Si, Ge)
(Elsevier, 2019-05-02)
A detailed study of the magnetocaloric properties of six compounds of the intermetallic family RTX (R = Nd, Gd; T = Sc, Ti ; X = Si, Ge) has been undertaken: NdScSi, NdScGe, GdScSi, GdScGe, GdSc(Si0.5Ge0.5) and Gd(Sc0.5Ti0.5)Ge. ...
Critical behavior of the ferromagnetic transition in GdSc(Si,Ge) intermetallic compounds
(Elsevier, 2018-07-26)
A complete study on the critical behavior of the paramagnetic to ferromagnetic transition in intermetallics GdScSi, GdScGe, GdSc(Si0.5Ge0.5) and Gd(Sc0.5Ti0.5)Ge has been carried out by means of magnetic as well as ...
Critical behavior study of magnetic transitions in Dy3Co single crystals
(Elservier, 2018-02-14)
An ac photopyroelectric calorimeter has been used to study the critical behaviour of the magnetic transitions in Dy3Co measuring thermal diffusivity, specific heat and thermal conductivity, at low temperature. There are ...
Perturbation-Theory and Machine Learning (PTML). Model for High-Throughput Screening of Parham Reactions: Experimental and Theoretical Studies
(American Chemical Society, 2018-06-13)
Machine Learning (ML) algorithms are gaining importance in the processing of chemical information and modelling of chemical reactivity problems. In this work, we have developed a PTML model combining Perturbation-Theory ...
Thermal Diffusivity Measurement of Laser‐ Deposited AISI H13 Tool Steel and Impact on Cooling Performance of Hot Stamping Tools
(MDPI, 2020-01-20)
Additive manufacturing is a technology that enables the repair and coating of high‐addedvalue
parts. In applications such as hot stamping, the thermal behavior of the material is essential
to ensure the proper operation ...
Measurement of the thermal conductivity of fluids using laser spot lock-in thermography
(Elsevier, 2020-03-25)
In this work, we propose a new method to retrieve the thermal conductivity of fluids, kf, using laser spot
lock-in infrared thermography. The measurement cell consists in two paralepidid blocks separated by a
narrow gap ...
Measuring the in-plane thermal diffusivity of moving samples using laser spot lock-in thermography
(Elsevier, 2020-01-21)
In this work we deal with samples that move at constant speed and are illuminated by a modulated and focused
laser beam. We have obtained a general expression for the surface temperature of these moving samples: it is
valid ...
Measurement of in-plane thermal diffusivity of solids moving at constant velocity using laser spot infrared thermography
(Elsevier, 2018-11-07)
In this work, an infrared thermography setup is proposed to measure the in-plane thermal diffusivity of
(an)isotropic samples that are moving at constant velocity, as it is the case of in-line production or in-line
quality ...
Thermal effusivity measurements of thermal insulators using the photopyroelectric technique in the front configuration
(Elsevier, 2018-03-21)
In the photopyroelectric (PPE) technique in the front configuration one surface of a pyroelectric sensor is illuminated by a modulated laser beam, whereas the other surface is in contact with the sample under study. A ...
Carbopalladation/Suzuki Coupling Cascade for the Generation of Quaternary Centers. Access to Pyrrolo[1,2-b]isoquinolines
(American Chemical Society, 2019-07-29)
A convergent route to pyrrolo[1,2-b]isoquinolines with a quaternary center at C-10 has been
developed, that implies a sequential Pd(0)-catalyzed carbopalladation followed by cross-coupling
reaction with boronic acids. ...
