The effect of strontium incorporation into sol-gel biomaterials on their protein adsorption and cell interactions
(Elsevier, 2019-02-01)
It is known strontium can both inhibit the osteoclast formation and stimulate the osteoblast maturation, so biomaterials containing this element can favour bone structure stabilisation. The addition of Sr to biomaterials ...
Complete Characterization of Thermoelectric Materials by Impedance Spectroscopy
(American Chemical Society, 2019-05-01)
Thermoelectric materials can directly convert waste heat into electricity. Because of the vast amount of energy available as waste heat in our society, these materials could contribute to reduce our dependence on fossil ...
Looking for Energy Losses of a Rotary Permanent Magnet Magnetic Refrigerator to Optimize Its Performances
(MDPI, 2019-11-19)
: In this paper, an extensive study on the energy losses of a magnetic refrigerator prototype
developed at University of Salerno, named ‘8MAG’, is carried out with the aim to improve the
performance of such a system. The ...
Characterization of thermal contacts between heat exchangers and a thermoelectric module by impedance spectroscopy
(Elsevier, 2019)
Heat to electricity energy conversion efficiency of a thermoelectric (TE) device is not only influenced by the TE materials properties, but it also depends on the temperature difference between both sides of the TE legs. ...
Admittance study of grid-connected VSCs for harmonic oscillatory instabilities
(IET, 2019-07)
Voltage source converters (VSCs) can reduce damping of grid-connected VSC systems at harmonic resonances, leading to system instability. The conductance of the VSC admittance can be shaped selecting appropriate VSC parameter ...
Experimental conditions required for accurate measurements of electrical resistivity, thermal conductivity, and dimensionless figure of merit (ZT) using Harman and impedance spectroscopy methods
(AIP Publishing, 2019-01-11)
The Harman method is used extensively for the characterization of the dimensionless figure of merit ZT of thermoelectric (TE) materials and devices. However, its accuracy has often been questioned, since in many cases there ...
Arquitecturas interactivas. Prácticas visuales emergentes en la ciudad interfaz
(Universidad Politécnica de Valencia, 2019)
We are living the transition from
a static to a dynamic architecture
driven by the integration of new
technologies into the urban
environment. In this scenario,
citizens abandon their passive
roles in order to ...
Complement proteins regulating macrophage polarisation on biomaterials
(Elsevier, 2019-09-01)
One of the events occurring when a biomaterial is implanted in an host is the protein deposition onto its surface, which might regulate cell responses. When a biomaterial displays a compromised biocompatibility, distinct ...
Impedance spectroscopy characterization of neutron irradiated thermoelectric modules for space nuclear power
(AIP Publishing, 2019)
The European Space Agency is currently supporting the research and development of advanced radioisotope power systems utilising thermoelectric modules. The performance of thermoelectric modules following exposure to neutron ...
Influence of operational modes of the internal heat exchanger in an experimental installation using R-450A and R-513A as replacement alternatives for R-134a
(Elsevier, 2019-12-15)
This paper presents a first and second law of thermodynamics study using experimental data from a medium capacity refrigeration system using R-450A, R-513A and R-134a as working fluids and an internal heat exchanger (IHX) ...
