    • Adverse Effect of PTFE Stir Bars on the Covalent Functionalization of Carbon and Boron Nitride Nanotubes Using Billups–Birch Reduction Conditions 

      de los Reyes, Carlos A.; Smith McWilliams, Ashleigh D.; Hernández, Katharyn; Walz-Mitra, Kendahl L.; Ergülen, Selin; Pasquali, Matteo; Martí, Angel A. (2019)
      The functionalization of nanomaterials has long been studied as a way to manipulate and tailor their properties to a desired application. Of the various methods available, the Billups–Birch reduction has become an important ...
    • Biocompatible Carbon Nanotube–Chitosan Scaffold Matching the Electrical Conductivity of the Heart 

      Pok, Seokwon; Vitale, Flavia; Eichmann, Shannon L.; Benavides, Omar M.; Pasquali, Matteo; Jacot, Jeffrey G. (2014)
      The major limitation of current engineered myocardial patches for the repair of heart defects is that insulating polymeric scaffold walls hinder the transfer of electrical signals between cardiomyocytes. This loss in signal ...
    • Carbon nanotube fiber terahertz polarizer 

      Zubair, Ahmed; Tsentalovich, Dmitri E.; Young, Colin C.; Heimbeck, Martin S.; Everitt, Henry O.; Pasquali, Matteo; Kono, Junichiro (2016)
      Conventional, commercially available terahertz (THz) polarizers are made of uniformly and precisely spaced metallic wires. They are fragile and expensive, with performance characteristics highly reliant on wire diameters ...
    • Charged iodide in chains behind the highly efficient iodine doping in carbon nanotubes 

      Zubair, Ahmed; Tristant, Damien; Nie, Chunyang; Tsentalovich, Dmitri E.; Headrick, Robert J.; Pasquali, Matteo; Kono, Junichiro; Meunier, Vincent; Flahaut, Emmanuel; Monthioux, Marc; Gerber, Iann C.; Puech, Pascal (2017)
      The origin of highly efficient iodine doping of carbon nanotubes is not well understood. Relying on first-principles calculations, we found that iodine molecules (I2) in contact with a carbon nanotube interact to form ...
    • Competing mechanisms and scaling laws for carbon nanotube scission by ultrasonication 

      Pagani, Guido; Green, Micah J.; Poulin, Philippe; Pasquali, Matteo (2012)
      Dispersion of carbon nanotubes (CNTs) into liquids typically requires ultrasonication to exfoliate individuals CNTs from bundles. Experiments show that CNT length drops with sonication time (or energy) as a power law t?m. ...
    • Experimental realization of crossover in shape and director field of nematic tactoids 

      Jamali, Vida; Behabtu, Natnael; Senyuk, Bohdan; Lee, J. Alex; Smalyukh, Ivan I.; van der Schoot, Paul; Pasquali, Matteo (2015)
      Spindle-shaped nematic droplets (tactoids) form in solutions of rod-like molecules at the onset of the liquid crystalline phase. Their unique shape and internal structure result from the interplay of the elastic deformation ...
    • High-Ampacity Power Cables of Tightly-Packed and Aligned Carbon Nanotubes 

      Wang, Xuan; Behabtu, Natnael; Young, Colin C.; Tsentalovich, Dmitri E.; Pasquali, Matteo; Kono, Junichiro (2014)
      The current-carrying capacity (CCC), or ampacity, of highly-conductive, light, and strong carbon nanotube (CNT) fibers is characterized by measuring their failure current density (FCD) and continuous current rating (CCR) ...
    • Strong, Light, Multifunctional Fibers of Carbon Nanotubes with Ultrahigh Conductivity 

      Behabtu, Natnael; Young, Colin C.; Tsentalovich, Dmitri E.; Kleinerman, Olga; Wang, Xuan; Ma, Anson W.K.; Bengio, E. Amram; ter Waarbeek, Ron F.; de Jong, Jorrit J.; Hoogerwerf, Ron E.; Fairchild, Steven B.; Ferguson, John B.; Maruyama, Benji; Kono, Junichiro; Talmon, Yeshayahu; Cohen, Yachin; Otto, Marcin J.; Pasquali, Matteo (2013)
      Broader applications of carbon nanotubes to real-world problems have largely gone unfulfilled because of difficult material synthesis and laborious processing. We report high-performance multifunctional carbon nanotube ...
    • Surfactant-assisted individualization and dispersion of boron nitride nanotubes 

      McWilliams, Ashleigh D. Smith; Reyes, Carlos A. de los; Liberman, Lucy; Ergülen, Selin; Talmon, Yeshayahu; Pasquali, Matteo; A. Martí, Angel (2019)
      Boron nitride nanotubes (BNNTs) belong to a novel class of material with useful thermal, electronic and optical properties. However, the study and the development of applications of this material requires the formation of ...
    • Synthesis and Crystal Structure of Gold Nanobelts 

      Payne, Courtney M.; Tsentalovich, Dmitri E.; Benoit, Denise N.; Anderson, Lindsey J.E.; Guo, Wenhua; Colvin, Vicki L.; Pasquali, Matteo; Hafner, Jason H. (2014)
      Gold nanobelts were synthesized by the reduction of tetrachloroauric acid with ascorbic acid in the presence of the surfactants cetyltrimethylammonium bromide and sodium dodecylsulfate. The resulting structures have ...
    • Theoretical analysis of selectivity mechanisms in molecular transport through channels and nanopores 

      Agah, Shaghayegh; Pasquali, Matteo; Kolomeisky, Anatoly B. (2015)
      Selectivity is one of the most fundamental concepts in natural sciences, and it is also critically important in various technological, industrial, and medical applications. Although there are many experimental methods that ...
