A Commercial Conducting Polymer as Both Binder and Conductive Additive for Silicon Nanoparticle-Based Lithium-Ion Battery Negative Electrodes
COLEMAN, JONATHAN; NICOLOSI, VALERIA; DUESBERG, GEORG; MCEVOY, NIALL (2016)This work describes silicon nanoparticle-based lithium-ion battery negative electrodes where multiple non-active electrode additives (usually carbon black and an inert polymer binder) are replaced with a single conductive ... -
A comparison of catabolic pathways induced in primary macrophages by pristine single walled carbon nanotubes and pristine graphene
COLEMAN, JONATHAN; NICOLOSI, VALERIA; VOLKOV, YURI; O'NEILL, LUKE; MCGOVERN, IGNATIUS; NERL, HANNAH; DUESBERG, GEORG; MCEVOY, NIALL (2016)Understanding the correlation between the physico-chemical properties of carbonaceous nanomaterials and how these properties impact on cells and subcellular mechanisms is critical to their risk assessment and safe translation ... -
Covalently functionalized hexagonal boron nitride nanosheets by nitrene addition
SATTI, AMRO; COLEMAN, JONATHAN NESBIT; GOUNKO, IOURI; MAY, PETER; O'NEILL, ARLENE; NICOLOSI, VALERIA (Wiley, 2012)Exfoliated h-BN nanosheets were covalently functionalized via a one-step nitrene addition using azide precursor molecules. Functionalized h-BN nanosheets were found to exhibit markedly enhanced dispersability relative to ... -
Effect of percolation on the capacitance of supercapacitor electrodes prepared from composites of manganese dioxide nanoplatelets and carbon nanotubes
COLEMAN, JONATHAN; BERNER, NINA; DUESBERG, GEORG; NICOLOSI, VALERIA; MCEVOY, NIALL (2014)Here we demonstrate significant improvements in the performance of supercapacitor electrodes based on 2D MnO2 nano-platelets by the addition of carbon nanotubes. Electrodes based on MnO2 nano-platelets do not display high ... -
Large-Scale Exfoliation of Inorganic Layered Compounds in Aqueous Surfactant Solutions
COLEMAN, JONATHAN; WANG, JING; KHAN, UMAR; NICOLOSI, VALERIA; DUESBERG, GEORG (2011)Thumbnail image of graphical abstract A method to exfoliate MoS2 in large quantities in surfactant-water solutions is described. The layered material tends to be exfoliated as dispersions of thin, relatively defect-free ... -
Liquid Exfoliation of Layered Materials
COLEMAN, JONATHAN; NICOLOSI, VALERIA (2013)Not all crystals form atomic bonds in three dimensions. Layered crystals, for instance, are those that form strong chemical bonds in-plane but display weak out-of-plane bonding. This allows them to be exfoliated into ... -
Long-chain amine-templated synthesis of gallium sulfide and gallium selenide nanotubes
COLEMAN, JONATHAN; NICOLOSI, VALERIA; RODE, KARSTEN; NERL, HANNAH; POKLE, ANUJ; DUESBERG, GEORG; MCEVOY, NIALL (2016)We describe the soft chemistry synthesis of amine-templated gallium chalcogenide nanotubes through the reaction of gallium(iii) acetylacetonate and the chalcogen (sulfur, selenium) using a mixture of long-chain amines ... -
Production of Molybdenum Trioxide Nanosheets by Liquid Exfoliation and Their Application in High-Performance Supercapacitors
COLEMAN, JONATHAN; DUESBERG, GEORG; NICOLOSI, VALERIA; MCEVOY, NIALL; MENDOZA SANCHEZ, BEATRIZ (2014)Here, we demonstrate a simple method to exfoliate layered molybdenum trioxide (MoO3) crystallites to give multilayer MoO3 nanosheets dispersed in solvents. Exfoliation is achieved by sonicating MoO3 powder in the presence ... -
