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. ...
Field validation of gap-type overhead conductor creep
(Elsevier, 2018-09-11)
Gap-type overhead conductor sag-tension calculations based on experimental conductor creep tests are based on stress-strain and metallurgical creep tests. Although for bi-metallic conductors, these tests are carried out ...
Do Employee-Owned Firms Produce More Positive Employee Behavioural Outcomes? If Not Why Not? A British-Spanish Comparative Analysis
(John Wiley & Sons Ltd, 2017-06-07)
[EN]Whether ‘employee ownership’ takes the form of worker cooperatives, co-ownership or simply employee share ownership plans, there are normally high expectations that a range of positive outcomes will result. Yet many ...
