In the present work, an interferometric unsteady analysis of the thermogravitational technique was for the first time attempted in a paralelepipedic microcolumn
using binary mixtures with negative Soret coefficients. In ...
Thermophoresis as a technique for separation of nanoparticle species in microfluidic devices
(Elsevier Masson SAS, 2020)
This paper presents numerical studies of thermophoresis approach for separation of nanoparticles in liquid media. We simulated the thermophoresis process to test it as a method of separation of particles in suspension. At ...

Adaptive coatings based on polyaniline for direct 2D observation of diffusion processes in microfluidic systems
(Elsevier, 2016)
Microfluidic devices are poised to dramatically influence the future of the process industry. Therefore the understanding and proper evaluation of the flow and mixing behaviour at microscale becomes a very important issue. ...
Determination of the molecular diffusion coefficients in ternary mixtures by the sliding symmetric tubes technique
(AIP Publishing, 2014)
A new analytical methodology has been developed to determine the diagonal and cross-diagonal molecular diffusion coefficients in ternary mixtures by the Sliding Symmetric Tubes technique. The analytical solution is tested ...
Radiant waste heat recovery from steelmaking and glass industry
(Edp Sciences, 2019)
This paper tackles the problem of industrial waste heat recovery through an unexploited heat transfer mechanism: thermal radiation. Energy intensive industries have a considerable potential of unused radiant heat, which ...
Contact angle measurement for LiBr aqueous solutions on different surface materials used in absorption systems
(Elsevier Ltd., 2018)
Wetting surface is a very important issue for the design of absorption applications and heat exchangers. The contact angle is deemed essential in wettability studies; However, LiBr aqueous solution contact angle studies ...
CFD Analysis of can Heating Process

Iron magnetic nanoparticles were produced by the technique of the electric explosion of a wire (EEW). The major crystalline phase (95 ± 1%) was α-Fe with lattice parameter a = 0.2863(3) nm. The size of the coherent diffraction ...
Optimizing Polymer Lab-on-Chip Platforms for Ultrasonic Manipulation: Influence of the Substrate
(MDPI, 2015)
The choice of substrate material in a chip that combines ultrasound with microfluidics for handling biological and synthetic microparticles can have a profound effect on the performance of the device. This is due to the ...
Digital Interferometry Applied to Thermogravitational Technique
