Dynamic analysis of a recirculation system of micro functional fluids for ink-jet applications
(Springer Verlag, 2017-05-01)
The rise of ink-jet printing technology has led to numerous studies about functional fluids, which, in most cases, are made to change and improve the chemical and rheological properties. Besides this, there are several ...
Determination of Size Distributions of Concentrated Polymer Particles Embedded in a Solid Polymer Matrix
(Wiley VCH Verlag, 2008-04)
In this work we present the results obtained from the size characterization of polymer particles embedded in a solid polymer matrix using Static Light Scattering (SLS) and Scanning Electron Microscopy (SEM). The analyzed ...
Particle size effects on magnetic properties of yttrium iron garnets prepared by a sol-gel method
(Elsevier Science, 2002-05)
We present detailed measurements of field - and temperature - dependence of magnetization in nanocrystalline YIG (Y3Fe5O12) particles. The fine powders were prepared using sol-gel method. Samples with particle sizes ranging ...
Water movement caused by spreading surfactants in unsaturated systems of particles of nonuniform size
(Taylor & Francis, 2007-04-27)
The movement of water originated by the spreading of two surfactants was analyzed in glass beads as well as on soil systems, both of particles of nonuniform size The higher difference of surface tension produced in the ...
Size and surface effects in the magnetic order of CoFe2O4 nanoparticles
(Elsevier Science, 2015-03)
In this work, we have focused on the size dependence of the magnetic properties and the surface effects of CoFe2O4 nanoparticles synthesized by high-temperature chemical method with diameter d~2, 4.5, and 7 nm, with narrow ...
Effect of drug molecular weight on niosomes size and encapsulation efficiency
(Elsevier Science, 2020-02)
Encapsulation into nanocarriers, such as niosomes, is a promising way to protect them from degradation, and allow controll and target delivery of bioactive compounds. For biotechnological applications, a tight control of ...
Flow properties of caseinomacropeptide aqueous solutions: Effect of particle size distribution, concentration, pH and temperature
(Elsevier Science, 2018-07)
The purpose of this research was to evaluate the influence of particle size distribution, pH (5.0–9.0), concentration (1–15 g/100 g.) and temperature (5–60 °C) on the steady shear flow properties of caseinomacropeptide ...
Flocking dynamics with voter-like interactions
(IOP Publishing, 2018-03)
We study the collective motion of a large set of self-propelled particles subject to voter-like interactions. Each particle moves on a 2D space at a constant speed in a direction that is randomly assigned initially. Then, ...
Combination of indirect measurements to improve sigmal estimation
(Planta Piloto de Ingeniería Química, 2000-12)
A form to combine two kinds of indirect measurements to be processed together is proposed for illconditioned problems. Linear individual measurements with unknown proportionality constants jointly considered determine a ...
