Robustness study for networked event-based control system under Regular Quantization with Hysteresis sampling
(Institute of Electrical and Electronics Engineers Inc., 2024-07-24)
The robustness against the apparition of limit cycle oscillations induced by a class of event-based sampling used in networked control systems is analyzed. Concretely, the Regular Quantization with Hysteresis sampling ...
Evaluation of the inflammatory responses to sol–gel coatingswith distinct biocompatibility levels
(John Wiley and SonsWileyWiley PeriodicalsSociety For Biomaterials (USA)Japanese Society for BiomaterialsAustralasian Society for BiomaterialsKorean Society for Biomaterials, 2021-02-20)
The immune system plays a crucial role in determining the implantation outcome, and macrophages are in the frontline of the inflammatory processes. Further, cellular oxidative stress resulting from the material recognition ...
On the relationship between the specific heat enhancement of salt-based nanofluids and the ionic exchange capacity of nanoparticles
(Nature Publishing Group, 2018)
Nanoparticles have been used in thermal applications to increase the specific heat of the molten salts used in Concentrated Solar Power plants for thermal energy storage. Although several mechanisms for abnormal enhancement ...
Stabilization and characterization of a nanofluid based on a eutectic mixture of diphenyl and diphenyl oxide and carbon nanoparticles under high temperature conditions
(Elsevier, 2017-06)
(C12H10O), and it is used as an HTF with a maximum working temperature of 400 °C. However, one of the drawbacks of Therminol VP1 is its low thermal conductivity. In recent years it has been demonstrated that the addition ...
Increment of specific heat capacity of solar salt with SiO2 nanoparticles
(Springer, 2014)
Thermal energy storage (TES) is extremely important in concentrated solar power (CSP) plants since it represents the main difference and advantage of CSP plants with respect to other renewable energy sources such as wind, ...

Tribological Analysis and Operation Issues of SiO2 Nanolubricants for MQL Machining Operations
(Trans Tech Publications, 2023-10)
Minimum Quantity Lubrication (MQL) has been proved to be an efficient lubricant technique in machining that increases tool life, improves surface roughness, facilitates the recycling of the resulting chips, brings more ...
Characterization of halloysite-water nanofluid for heat transfer applications
(Elsevier, 2014-07-04)
Nanofluids based on water with halloysite (Hal) nanotubes were prepared and characterized in order to evaluate its suitability to be used as a heat transfer fluid. A characterization of the Hal powder nanoparticles was ...
Fault-tolerant strategies in MMC-based high power magnet supply for particle accelerator
(Elsevier, 2023)
Many particle accelerators require to supply chains of magnets with high quality, high magnitude, cycling currents. To
do this, the power converters need to provide high output voltages, reaching in some cases tens of ...
