Thermodiffusion in multicomponent n-alkane mixtures
(Nature Research (Part of Springer Nature), 2017)
Compositional grading within a mixture has a strong impact on the evaluation of the pre-exploitation distribution of hydrocarbons in underground layers and sediments. Thermodiffusion, which leads to a partial diffusive ...

Microfluidic separation processes using the thermodiffusion effect
(Elsevier B.V., 2018)
The numerical and experimental results presented in this work show that a relatively small temperature gradient
(5K), has great potential to generate a separation in interesting mixtures for biological purpose. In fact, ...
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 ...
Stability analysis under thermogravitational effect

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 ...
Contact angle measurement for LiBr aqueous solutions on different surface materials used in absorption systems
