This review focuses on the reports (experimental or theoretical) of systems using these structures decorated with transition metals for mainly pollutant molecules’ adsorption. Furthermore, we aim to present the expanding application of nanomaterials on environmental problems, mainly over the last 10 years. We found a wide range of pollutant molecules investigated for adsorption in carbon nanostructures, including greenhouse gases, anticancer drugs, and chemical warfare agents, among many more.

Graphene is a smart material that responds to any physical change in its surrounding environment. Graphene has a very low intrinsic electronic noise and it can detect even a single gas molecule in its proximity. This property of graphene makes is a suitable and promising candidate to detect a large variety of organic/inorganic chemicals and gases. Typical solid state gas sensors usually requires high operating temperature and they cannot detect very low concentrations of gases efficiently due to intrinsic noise caused by thermal motion of charge carriers at high temperatures. They also have low resolution and stability issues of their constituent materials (such as electrolytes, electrodes, and sensing material itself) in harsh environments. It accelerates the need of development of robust, highly sensitive and efficient gas sensor with low operating temperature. Graphene and its derivatives could be a prospective replacement of these solid-state sensors due to their better electronic attributes for moderate temperature applications. The presence of extremely low intrinsic noise in graphene makes it highly suitable to detect a very low concentration of organic/inorganic compounds (even a single molecule ca be detected with graphene). -

MOLECULAR MACHINES AND MOTORS We study the motion of C60 fullerene molecules and short-length carbon nanotubes on graphene CARBON NANOTUBES AND nanoribbons. We reveal that the character of the motion of C60 depends on temperature: for T , 150 K the FULLERENES main type of motion is sliding along the surface, but for higher temperatures the sliding is replaced by rocking and rolling. Modeling of the buckyball with an included metal ion demonstrates that this molecular complex undergoes a rolling motion along the nanoribbon with the constant velocity under the action of a Received constant electric field. The similar effect is observed in the presence of the heat gradient applied to the 27 June 2012 nanoribbon, but mobility of carbon structures in this case depends largely on their size and symmetry, such that larger and more asymmetric structures demonstrate much lower mobility. Our results suggest that both Accepted electorphoresis and thermophoresis can be employed to control the motion of carbon molecules and 29 October 2012 fullerenes. Published 20 December 2012 ver the past 20 years nanotechnology has made an impressive impact on the development of many fields of physics, chemistry, medicine, and nanoscale engineering1.

Non-bonded interactions are dominated by repulsive forces at short range and attractive dispersion forces at long range. Experimental data on the detailed interaction potentials for non-bonded interatomic and intermolecular forces is scarce.

Heerema, Leonardo Vicarelli, Sergii Pud, Raymond N. Schouten, Henny W. Zandbergen, and Cees Dekker* Kavli Institute of Nanoscience Delft, Delft University of Technology, Van der Maasweg 9, 2629 HZ Delft, The Netherlands *S Supporting Information ABSTRACT: Many theoretical studies predict that DNA sequencing should be feasible by monitoring the transverse current through a graphene nanoribbon while a DNA molecule translocates through a nanopore in that ribbon. Such a readout would benefit from the special transport properties of graphene, provide ultimate spatial resolution because of the single-atom layer thickness of graphene, and facilitate high-bandwidth measurements. Previous experimental attempts to measure such transverse inplane signals were however dominated by a trivial capacitive response. Here, we explore the feasibility of the approach using a custom-made differential current amplifier that discriminates between the capacitive current signal and the resistive response in the graphene. We fabricate well-defined short and narrow (30 nm × 30 nm) nanoribbons with a 5 nm nanopore in graphene with a high-temperature scanning transmission electron microscope to retain the crystallinity and sensitivity of the graphene. We show that, indeed, resistive modulations can be observed in the graphene current due to DNA translocation through the nanopore, thus demonstrating that DNA sensing with inplane currents in graphene nanostructures is possible. -

Fax: +49-30-838 53464. E-mail: [email protected] Z. Naturforsch. 2010, 65b, 1 – 7; received October 1, 2009 The electron density of the C70 fullerene C70(C2F5)10 was determined from a high-resolution X-ray data set measured with synchrotron radiation (beamline F1 of Hasylab/DESY, Germany) at a temperature of 100 K. With 140 atoms in the asymmetric unit this fullerene belongs to the largest problems examined until now by electron density methods. Using the QTAIM formalism quantitative bond topological and atomic properties have been derived and compared with the results of theoretical calculations on the title compound and on free C70. Key words: Fullerenes, Electron Density, Topological Analysis, Synchrotron Radiation Introduction Although recent technical and methodical advances made experimental electron density (ED) determina- tions possible also on larger molecules, fullerenes with 60 or more atoms are still a major challenge. Their in- vestigation is complicated by the generally poor crystal quality and by the high mobility of these molecules in the crystal structure. Since their discovery in the mid- eighties a considerable number of more than 800 X-ray structures of fullerenes and fullerene derivatives are listed in the Cambridge Data File [1]. -

Large-Scale Solution Synthesis of Narrow Graphene Nanoribbons
ARTICLE Received 13 Aug 2013 | Accepted 2 Jan 2014 | Published 10 Feb 2014 DOI: 10.1038/ncomms4189 Large-scale solution synthesis of narrow graphene nanoribbons Timothy H. Vo1, Mikhail Shekhirev1, Donna A. Kunkel2, Martha D. Morton1, Eric Berglund1, Lingmei Kong2, Peter M. Wilson1, Peter A. Dowben2,3, Axel Enders2,3 & Alexander Sinitskii1,3 According to theoretical studies, narrow graphene nanoribbons with atomically precise armchair edges and widths of o2 nm have a bandgap comparable to that in silicon (1.1 eV), which makes them potentially promising for logic applications. Different top–down fabrication approaches typically yield ribbons with width 410 nm and have limited control over their edge structure. Here we demonstrate a novel bottom–up approach that yields gram quantities of high-aspect-ratio graphene nanoribbons, which are only B1 nm wide and have atomically smooth armchair edges. These ribbons are shown to have a large electronic bandgap of B1.3 eV, which is significantly higher than any value reported so far in experimental studies of graphene nanoribbons prepared by top–down approaches. These synthetic ribbons could have lengths of 4100 nm and self-assemble in highly ordered few-micrometer-long ‘nanobelts’ that can be visualized by conventional microscopy techniques, and potentially used for the fabrication of electronic devices. 1 Department of Chemistry, University of Nebraska–Lincoln, Lincoln, Nebraska 68588, USA. 2 Department of Physics, University of Nebraska–Lincoln, Lincoln, Nebraska 68588, USA. 3 Nebraska Center for Materials and Nanoscience, University of Nebraska–Lincoln, Lincoln, Nebraska 68588, USA.
