Laser sintered ceramic coatings of PZT nanoparticles deposited by Inkjet Printing on metallic and ceramic
(Elsevier, 2018)Lead zirconate titanate (PZT) Pb(ZrxTi1-x)O3 is one of the most studied perovskite type ferroelectric materials due to its excellent dielectric, piezoelectric and ferroelectric properties. PZT particles and a PZT precursor ... -
Microstructural comparison between precursor-based and particle-based PZT ceramic coatings
(Elsevier, 2019)Piezoelectric materials are used in several applications, including sensors and actuators. Perovskite type ferroelectrics, specially, lead zirconate titanate (PZT), due to its excellent dielectric, piezoelectric and ... -
Identification of interaction mechanisms during drag finishing by means of an original macroscopic numerical model
(Elsevier, 2021)Drag finishing is one of the mass finishing processes that enhances surface roughness on complex parts due to the mechanical action of abrasive media. Due to the complexity of the process, industrial practice is based on ... -
Metal-Free Polymethyl Methacrylate (PMMA) Nanoparticles by Enamine “Click” Chemistry at Room Temperature
(MDPI, 2011)“Click” chemistry has become an efficient avenue to unimolecular polymeric nanoparticles through the self-crosslinking of individual polymer chains containing appropriate functional groups. Herein we report the synthesis ... -
Role of specific interactions on fiber formation in the electrospinning of poly (vinyl phenol)/ poly (vinyl pyrrolidone) blend solutions
(Wiley, 2009)The minimum concentration (Ci) required for electrospinning polymeric fibers from solutions of mixtures of poly(vinyl phenol) and poly(vinyl pyrrolidone) has been experimentally determined for different blend compositions. ... -
Easy-dispersible poly(glycidyl phenyl ether)-functionalized graphene sheets obtained by reaction of "living'' anionic polymer chains
(Royal Society of Chemistry, 2012)Excellent dispersion of functionalized graphene (FG) sheets in polystyrene was achieved relying on the reaction of “living” poly(glycidyl phenyl ether) chains onto graphene sheets. The physical aging of polystyrene was ... -
Naked and Self-Clickable Propargylic-Decorated Single-Chain Nanoparticle Precursors via Redox-Initiated RAFT Polymerization
(Wiley, 2012)Protection of acetylenic monomers is a common practice to avoid parasitic side reactions during polymerization. Herein, we report that redox-initiated RAFT polymerization allows the direct, room temperature synthesis of a ... -
On the Apparent SEC Molecular Weight and Polydispersity Reduction upon Intramolecular Collapse of Polydisperse Chains to Unimolecular Nanoparticles
(ACS Publications, 2011)When unimolecular particles of molecular weight M are formed by intramolecular cross-linking of individual polymer chains, a significant reduction in hydrodynamic radius and, hence, apparent molecular weight (Mapp) is found ... -
Electrospinning of waterborne polyurethanes
(Wiley, 2010)Polyurethane (PU) fibers were obtained by electrospinning of waterborne PU dispersions. As dispersion cannot be electrospun, a water-soluble polymer (poly (ethylene oxide) (PEO)) was dissolved in the PU dispersion and ... -
Electrospinning of poly (2-ethyl-2-oxazoline)
(Springer Nature, 2009)Poly (2-ethyl-2-oxazoline) (PEOZ) is one of the commercial members of a family of materials that have shown significant application potential in a large number of technological contexts, most of them related with biomedical ... -
An experimental methodology to improve the robotic drilling of aluminium alloys
(Elsevier, 2025)In aeronautics, mastering the drilling process is crucial to meet strict quality standards. While robots provide a cost-effective solution for drilling large, complex parts, challenges arise in metallic materials due to ... -
Effect of the supporting disks shape on nonlinear flow dynamics in a liquid bridge
(AIP Publishing, 2021)The stability of convective flows in a non-homogeneous temperature field is affected by the shape of the container hosting the fluid. We present a nonlinear two-phase computational study of convection in a liquid bridge ... -
A ternary mixture at the border of Soret separation stability
(Royal Society of Chemistry, 2021)Ternary mixtures with the Soret effect are prone to triple-diffusive convection in a thermal field. The Soret coefficients of the toluene–methanol–cyclohexane mixture, measured in microgravity at a given composition ... -
Estimation of the epidemiology of dementia and associated neuropsychiatric symptoms by applying machine learning to real-world data
(Elsevier, 2022)Introduction Incidence rates of dementia-related neuropsychiatric symptoms (NPS) are not known and this hampers the assessment of their population burden. The objective of this study was to obtain an approximate estimate ... -
El componente experiencial para la apropiación tecnológica
