Cation pumping against a concentration gradient in conical nanopores characterized by load capacitors

Cervera, Javier; Ramirez Hoyos, Patricio; Nasir, Saima; Mubarak, Ali; Ensinger, Wolfgang; Siwy, Zuzanna S.; Mafe, Salvador (Elsevier, 2023-08)

[EN] We study the cation transport against an external concentration gradient (cation pumping) that occurs in conical nanopores when zero-average oscillatory and white noise potentials are externally applied. This pumping, ...
Effect of cationic polyamidoamine dendrimers on ionic transport through nanochannels

Froehlich, Kristina; Ali, Mubarak; Ramirez Hoyos, Patricio; Cervera Montesinos, Javier; García-Morales, Vladimir; Erdmann, Markus; Ensinger, Wolfgang (Elsevier, 2021-01-20)

[EN] The effect of polyamidoamine (PAMAM) dendrimers (generations G0-G3) on the ion transport properties of nanochannels (conical and cylindrical) is studied either by surface functionalization or by addition to the ...
Ionic conduction through single-pore and multipore polymer membranes in aprotic organic electrolytes

Nasir, Saima; Ali, Mubarak; Ramirez Hoyos, Patricio; Froehlich, Kristina; Cervera, Javier; Mafe, Salvador; Ensinger, Wolfgang (Elsevier, 2021-10-01)

[EN] We experimentally characterize the ionic conduction of single and multipore nanoporous membranes in aprotic organic electrolytes. To this end, soft-etched (SE) membranes with pore diameters in the nanometer range and ...
