• completely filled using this new technique. The nanopipettes are first filled with pure water, which is later replaced with the desired electrolyte via electromigration. Electrical measurements are used to check that filling is complete. Keywords: current rectification; distillation; filling; nanopipette

• and ICR (intensity current rectification) ratio of ICR500 = I−500mV/I+500mV = 1.53 at [KCl] = 10−4 mol·L−1 are comparable with previously measured values. This confirms that the proposed filling technique is reliable. Conclusion The successful filling of 100% of nanopipettes using dynamic

• interaction and spin–spin correlation between π-electrons and radicals, are highlighted. Several interesting functional designs of organic ferromagnetic devices are discussed, specifically the concepts of a spin filter, multi-state magnetoresistance, and spin-current rectification. The mechanism of each

• phenomenon is explained by transmission and orbital analysis. These works show that organic ferromagnets are promising components for spintronic devices that deserve to be designed and examined in future experiments.
