      Biological charge transfer via flickering resonance 

      Zhang, Y.; Liu, C.; Balaeff, A.; Skourtis, Spiros S.; Beratan, David N. (2014)
      Biological electron-transfer (ET) reactions are typically described in the framework of coherent two-state electron tunneling or multistep hopping. However, these ET reactions may involve multiple redox cofactors in van ...

      Long-range charge transport in single G-quadruplex DNA molecules 

      Livshits, G. I.; Stern, A.; Rotem, D.; Borovok, N.; Eidelshtein, G.; Migliore, A.; Penzo, E.; Wind, S. J.; Di Felice, R.; Skourtis, Spiros S.; Cuevas, J. C.; Gurevich, L.; Kotlyar, A. B.; Porath, D. (2014)
      DNA and DNA-based polymers are of interest in molecular electronics because of their versatile and programmable structures. However, transport measurements have produced a range of seemingly contradictory results due to ...

      Physical constraints on charge transport through bacterial nanowires 

      Polizzi, N. F.; Skourtis, Spiros S.; Beratan, David N. (2012)
      Extracellular appendages of the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 were recently shown to sustain currents of 10 10 electrons per second over distances of 0.5 microns [El-Naggar et al., Proc. ...

      Polymeric nanowires and nanopillars fabricated by template wetting 

      Kokonou, M.; Ioannou, G.; Rebholz, Claus; Doumanidis, C. C. (2013)
      Template wetting constitutes a common technique for the fabrication of elongated polymeric nanostructures such as nanorods, nanotubes, and nanowires. It is based on the infiltration of polymeric solutions inside the nanopores ...

      Review: Probing protein electron transfer mechanisms from the molecular to the cellular length scales 

      Skourtis, Spiros S. (2013)
      The mechanisms of bridge-mediated electron transfer (ET) reactions vary from coherent deep tunneling to thermally activated hopping. This short review focuses on some developments in the study of protein ET mechanisms at ...

      Strain-controlled magnetic domain wall propagation in hybrid piezoelectric/ferromagnetic structures 

      Lei, N.; Devolder, T.; Agnus, G.; Aubert, P.; Daniel, L.; Kim, J. -V; Zhao, W.; Trypiniotis, Theodossis; Cowburn, R. P.; Chappert, C.; Ravelosona, D.; Lecoeur, P. (2013)
      The control of magnetic order in nanoscale devices underpins many proposals for integrating spintronics concepts into conventional electronics. A key challenge lies in finding an energy-efficient means of control, as power ...
