Curso de Física para Ingeniería de Telecomunicación
Carpena-Sánchez, Pedro Juan; Criado-Aldeanueva, Francisco
; García-Lafuente, Jesús
; Ruiz-Reina, Emilio
; Vargas-Domínguez, Juan Miguel
(Servicio de Publicaciones y Divulgación Científica, 2006)
El estudio y conocimiento de los fundamentos de Física constituye un pilar importante en Ia formación de un ingeniero. El presente "Curso de Física para Ingeniería de Telecomunicación" ha sido concebido como texto base ... -
Dynamic viscosity of colloidal silica suspensions at low and high volume fractions.
Samavat, Siamak; Carrique-Fernández, Félix; Ruiz-Reina, Emilio
; Zhang, Wei; Williams, Paul Melvyn (Elsevier, 2018)
A comprehensive study was carried out on the dynamic viscosity of X30 silica dispersions at both high and low volume fractions of colloidal silica particles at various electrolyte ionic strength and pH values. Booth and ... -
Effects of finite counterion size and nonhomogeneous permittivity and viscosity of the solution on the electrokinetics of a concentrated salt-free colloid
Carrique-Fernández, Félix; Ruiz-Reina, Emilio
; Arroyo Roldán, Francisco José; López García, José Juan; Delgado Mora, Ángel Vicente (American Physical Society (APS), 2024)
In the present work, a general model of the electrokinetics and dielectric response of a concentrated salt-free colloid is developed which includes consideration of the finite size of the counterions released by the particles ... -
Electrokinetic and dielectric response of a concentrated salt-free colloid: Different approaches to counterion finite size effects.
Carrique-Fernández, Félix; Ruiz-Reina, Emilio
; Arroyo Roldán, Francisco José; Jiménez Olivares, María Luisa; Ahualli Yapur, Silvia; Delgado Mora, Ángel Vicente[et al.] (American Physical Society (APS), 2022)
In the present work, a general model is developed for the electrokinetics and di- electric response of a concentrated salt-free colloid that takes into account the finite size of the counterions released by the particles ... -
Electrothermoplasmonic flow in gold nanoparticles suspensions: nonlinear dependence of flow velocity on aggregate concentration
González-Gómez, Carlos David; Rica, Raúl A.; Ruiz-Reina, Emilio(Elsevier, 2023)
Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that ... -
Influence of ion size effects on the electrokinetics of aqueous salt-free colloids in alternating electric fields
Carrique-Fernández, Félix; Ruiz-Reina, Emilio
; Arroyo Roldán, Francisco José; Delgado Mora, Ángel Vicente (American Physical Society (APS), 2020)
Electrokinetics is an important tool for the characterization of colloids because of its sensitivity to the electrical properties of particle-solution interfaces. Its rigorous description may require inclusion of the effects ... -
Non-monotonic concentration dependence of the electro-phoretic mobility of charged spheres in realistic salt free suspensions
Botin, Denis; Carrique-Fernández, Félix; Ruiz-Reina, Emilio
; Palberg, Thomas (AIP Publishing, 2020)
Using super-heterodyne Doppler velocimetry with multiple scattering correction, we extend the optically accessible range of concen- trations in experiments on colloidal electro-kinetics. Here, we measured the electro-phoretic ... -
Novel Techniques for Flow and Particle Control in Microfluidic Systems
González-Gómez, Carlos David (UMA Editorial, 2023)En los últimos años, los dispositivos lab-on-a-chip están atrayendo mucho interés. Estos aparatos de tamaño reducido, son capaces de albergar en la misma oblea una o varias de las funcionalidades típicas de los laboratorios ... -
Optical performance analysis of the Copenhagen solar cooker with COMSOL Multiphysics
García-Fernández, Jesús; Carrillo-Andrés, Antonio
; Apaolaza-Pagoaga, Xabier
; García-Ruiz, Antonio
; Ruiz-Reina, Emilio
(Elsevier, 2024-01-31)
The Copenhagen solar cooker is a compact, panel-type design with four flexible reflective panels to redirect solar radiation onto a cooking pot. The geometric configuration of the panels is adjustable, depending on the sun ...
