Electrical pumping of potassium ions against an external concentration gradient in a biological ion channel

Queralt-Martín, María; García Giménez, Elena; Aguilella, Vicente-Manuel; Ramirez Hoyos, Patricio; Mafé, Salvador; Alcaraz González, Antonio (American Institute of Physics (AIP), 2013-07)

We show experimentally and theoretically that significant currents can be obtained with a biological ion channel, the OmpF porin of Escherichia coli, using zero-average potentials as driving forces. The channel rectifying ...
Stabilized hierarchical USY zeolite catalysts for simultaneous increase in diesel and LPG olefinicity during catalytic cracking

Martínez, Cristina; Verboekend, Danny; Pérez-Ramírez, Javier; Corma Canós, Avelino (Royal Society of Chemistry, 2013)

Hierarchical USY zeolites obtained by scalable and affordable post-synthetic modifications (PSM) are stabilized by means of REO ion exchange and/or hydrothermal treatments, leading to FCC catalysts with improved hydrothermal ...
