Journal ArticleDOI
Efficient synthesis of ammonia from N2 and H2 alone in a ferroelectric packed-bed DBD reactor
Ana Gómez-Ramírez,José Cotrino,Richard M. Lambert,Richard M. Lambert,Agustín R. González-Elipe +4 more
TL;DR: A detailed study of ammonia synthesis from hydrogen and nitrogen in a planar dielectric barrier discharge (DBD) reactor was carried out in this article, where electrical parameters were systematically varied, including applied voltage and frequency, electrode gap, and type of ferroelectric material (BaTiO3 versus PZT).
Journal ArticleDOI
Colloids on the frontier of ferrofluids. Rheological properties.
Modesto T. López-López,Ana Gómez-Ramírez,Laura Rodríguez-Arco,Juan D. G. Durán,Larisa Iskakova,Andrey Zubarev +5 more
TL;DR: The experimental results demonstrate that upon magnetic field application these new ferro fluids develop yield stresses and magnetoviscous effects much greater than those of conventional ferrofluids, based on nanospheres of approximately 10 nm in diameter.
Journal ArticleDOI
Surface chemistry and germination improvement of Quinoa seeds subjected to plasma activation
Ana Gómez-Ramírez,Carmen López-Santos,Manuel Cantos,José Luis García,Rodrigo Molina,José Cotrino,Juan P. Espinós,Agustín R. González-Elipe +7 more
TL;DR: The disappearance from the surface of both potassium ions and nitrate species upon exposure of the plasma treated seeds to water vapor is proposed as a factor favoring germination.
Journal ArticleDOI
Influence of particle shape on the magnetic and magnetorheological properties of nanoparticle suspensions
TL;DR: In this article, CoNi nanofibers and nanospheres were synthesized by reduction of ions in a liquid polyol and their properties were characterized by means of electron microscopy, N2 adsorption, energy dispersive X-ray spectroscopy, Xray diffraction and magnetometry.
Journal ArticleDOI
Preparation and characterization of iron-based magnetorheological fluids stabilized by addition of organoclay particles.
TL;DR: These experiments showed that the addition of clay slows down iron particle settling and eases the redispersion of the iron-based suspensions without masking their magnetorheological properties.
