In our most recent works<br>we have disclosed a near universal trend where charge transfer governs the electrochemical<br>activation of carbon nanomaterials when exposed to potassium undergoing an electron<br>doping (e-doping) process. An entire picture of how electron doping alters the carbon<br>nanostructure vibrational response as a function of doping concentration and the structure of<br>the nanomaterial is evident, as well as the immediate changes revealed after they get exposed<br>to water, gases or pre-selected functionalities. We found three main important results: i)<br>Electron doping/intercalation works for majority of the carbon nanostructures (SWCNTs,<br>MWCTs, carbon nano-onions, graphite, graphene, and carbon nanoribbons). ii) There exist a<br>trend along the doping process in carbon nanotubes dependent on the nanotube diameter and<br>chirality. iii) Functional groups can be attached to the surface of the nanostructure without<br>damaging the crystallinity of the nanostructure. By combining theoretical and experimental<br>studies, we can cross confirm the effects of doping and functionalization that takes place by<br>induced charge transfer and alkali-metal intercalation. These studies are extended to none<br>carbon nanostructures revealing imprecedent novel results that could drive a new area of<br>study along the controlled synthesis of functional nanomaterials for optoelectronics, batteries<br>and sensing devices.<br></font></pre></pre><font face="arial, sans-serif" color="#000000">
