We will give a general historical introduction of Nanoscience and Nanotechnology. We will also discuss the synthesis of carbon nanotubes and nanotube networks using different dopants during chemical vapor deposition. In particular, the effects of sulfur, boron and nitrogen will be discussed. It will be demonstrated that it is indeed possible to assemble/grow carbon nanotube networks if a careful control of dopants is achieved during chemical vapor deposition (CVD) growth. High-resolution electron energy loss spectroscopy (HR-EELS) studies on these nanotube materials will be presented, and the locations of boron, sulfur and nitrogen within nanotubes will also be shown. First principles theoretical calculations on nanotubes containing pentagon, hexagons and heptagons in the presence of these dopants will be discussed. We will also discuss the cytotoxicity and applications as molecular sensors and virus traps of these doped nanocarbons.

This talk will also discuss the synthesis of large-area, high-quality monolayers of nitrogen-, silicon- and boron-doped graphene sheets on Cu foils using ambient-pressure chemical vapor deposition (AP-CVD). Scanning tunneling microscopy (STM) and spectroscopy (STS) reveal that the defects in the doped graphene samples arrange in different geometrical configurations exhibiting different electronic and magnetic properties. Interestingly, these doped layers could be used as efficient molecular sensors in conjunction with Raman spectroscopy. In addition, the synthesis of hybrid carbon materials consisting of interconnected graphene layers (graphene foams) by solvothermal routes will be discussed. These foams are highly conducting, very robust and can operate at temperatures ranging from 77K to 1173K.


Mauricio Terrones, obtained his B.Sc. degree in Engineering Physics with first class honors at Universidad Iberoamericana, and was distinguished as the Best Student of Mexico in Engineering Physics in 1992. In 1994 he started his doctorate degree with Sir Prof. Harold W. Kroto (Nobel Laureate, FRS), and received his D.Phil. degree from University of Sussex in 1998. He has co-authored more than 400 publications in international journals, and counts with more than 28,000 citations to his work (His H index is 83; Google Scholar H=91). He has published in Nature, Science, Phys. Rev. Lett., Nano Lett., Nature Nanotechnology, Nature Materials, Nature Communications, Nature Chemistry, ACS Nano, PNAS, etc. In 1999, he was awarded the Alexander von Humboldt Fellowship, and carried out research at the Max-Planck Institut für Metallforschung (Stuttgart, Germany). In 2000, he was recipient of the Mexican National Prize for Chemistry. He also received the Javed Husain Prize and the Albert Einstein medal from UNESCO in 2001. In 2005, he received the TWAS Prize in Engineering Physics for his contributions in the field of carbon-based nanomaterials. This prize is given by the Academy of Sciences of the Developing world, and Mauricio is the youngest scientist ever to receive any TWAS award. In 2005, Terrones also received the “José Antonio Villaseñor y Sánchez” Prize, awarded by the governor of the state of San Luis Potosí, for his contributions to Nanoscience. He is member of the Mexican Academy of Sciences since 2002. In 2007, Terrones was elected the National Contact Point in Nanotechnology with the European Union. In 2012 was elected fellow of the American Association for the Advancement of Science (AAAS). In 2015, he was elected fellow of the Royal Society of Chemistry (UK) and was awarded the Jubilee Professorship from Chalmers University of Technology (Sweden). In 2016, Mauricio was awarded the Faculty Scholar Medal in Physical Sciences (Penn State). Mauricio is also Associate Editor of Carbon, 2D Materials, Journal of Materials Research and Nature Scientific Reports. He is Professor of Physics, Chemistry and Materials Science & Engineering with tenure at Penn State University. He is also the Founder Director of the Center for 2-Dimensional and Layered Materials at Penn State, and also the NSF-IUCRC Center for Atomically Thin Multifunctional Coatings (ATOMIC).
