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. ... -
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 ... -
Definición de una metodología optimizada para la simulación del desgaste en materiales
(Consejo Superior de Investigaciones Científicas (CSIC), 2010)The wear simulation with finite element method (FEM) presents great advantages for the improvement of components, because of the reduction in the cost in comparison to the experimental procedure (test time, materials, ... -
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 ... -
Wear-related phenomena in advanced materials

Higher harmonics compensation in grid-connected PWM converters for renewable energy interface and active filtering
(Przegląd Elektrotechniczny, 2011)The paper presents overview of high-order harmonics compensation methods applied for control of grid-connected converter. Two harmonic compensation methods are presented. One based on band-pass filers cooperating with ... -
Thermodiffusion and molecular diffusion in binary n-alkane mixtures: experiments and numerical analysis
(Taylor&Francis, 2011)New experimental data on the thermodiffusion and molecular diffusion coefficients of nine non-equimolar binary mixtures of () at 298 K and 1 atm have been reported. The data have been obtained using a combination of the ... -
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 ... -
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 ... -
A neural-visualization IDS for honeynet data
(World Scientific, 2012)Neural intelligent systems can provide a visualization of the network traffic for security staff, in order to reduce the widely known high false-positive rate associated with misuse-based Intrusion Detection Systems (IDSs). ... -
Factor graph based detection approach for high-mobility OFDM systems with large FFT modes
(Springer, 2012)In this article, a novel detector design is proposed for orthogonal frequency division multiplexing (OFDM) systems over frequency selective and time varying channels. Namely, we focus on systems with large OFDM symbol ... -
Determination of molecular diffusion coefficient in n-Alkane binary mixtures: empirical correlations
(ACS Publishing, 2012)In this work we have measured the molecular diffusion coefficient of the n-alkane binary series nCi-nC6, nCi-nC10, and nCi-nC12 at 298 K and 1 atm and a mass fraction of 0.5 by using the so-called sliding symmetric tubes ... -
Sorption isotherm, glass transition, and diffusion coefficient of polyacrylamide/water solutions
(ACS Publications, 2012)The sorption isotherm, the glass transition, and the mutual diffusion coefficient of polyacrylamide/water solutions are obtained experimentally. All of these parameters are measured in the concentrated regime by gravimetric ... -
