  • Growing carbon nanotubes on graphite

    Publication Year: 2009, Page(s):128 - 132
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (575 KB)

    The processing and the resulting microstructures of carbon nanotubes (CNTs) grown on graphite nanosheets (GNSs) is examined. The GNSs have a planar shape and are 20-50-nm in thickness. The GNSs were made by the intercalation and exfoliation of natural graphite flakes. Nickel particles serving as the catalyst were distributed on the GNSs. A chemical vapour deposition (CVD) method was used to grow C... View full abstract»

  • Growth of spindle-shaped gold nanoparticles in cetyltrimethylammonium bromide solutions

    Publication Year: 2009, Page(s):142 - 147
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (721 KB)

    Spindle-shaped gold nanoparticles were successfully prepared in high yield by a simple wet chemical approach using L-ascorbic acid (AA) as reductant in the presence of cetyltrimethylammonium bromide (CTAB) at room temperature. Transmission electron microscopy, ultraviolet-visible absorption spectroscopy and X-ray diffraction have been used to characterise the obtained products. It is found that th... View full abstract»

  • Measurement of pull-off force for planar contact at the microscale

    Publication Year: 2009, Page(s):148 - 154
    Cited by:  Papers (8)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (439 KB)

    At the microscale, surface forces influence the behaviour of micro-objects more than volumic forces. During micro-assembly processes, contacts occur between a microgripper and a micro-object or between a substrate and a micro-object. The pull-off force, which represents the force required to break a contact, is one of the predominant problems in micro-assembly. Current force measurements are mostl... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (666 KB)

    A polymeric precursor, polyhydridomethylsilazane, was pyrolysed in an active ammonia atmosphere at 873 K with subsequent pyrolysis in an inert nitrogen atmosphere at 1873 K, and the polymer-derived ceramic products were studied using a field emission scanning electron microscope, X-ray diffractometer and high-resolution transmission electron microscope. No nanoneedles were observed in the 873 K py... View full abstract»

  • Cold-isopress-based process for fabrication of stainless steel micromachine components

    Publication Year: 2009, Page(s):160 - 165
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (664 KB)

    This letter presents in detail a new process for the fabrication of 3D stainless steel microcomponents using cold-isopressing techniques. The process starts by producing deep SU-8 master moulds and their negative soft micromoulds in polydimethylsiloxane (PDMS), preparing stainless steel semi-solid paste with high solid loading, filling the soft micromoulds, covering the filled moulds and putting t...

  • Use of nano-silica carriers for the fabrication of Li2o/MgO catalyst nano-particles on the surface of alpha-alumina supports

    Publication Year: 2009, Page(s):166 - 171
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (470 KB)

    A novel method for the production of detached ceramic oxide catalyst nano-particles on ceramic supports is presented. By the addition of a W/O micro-emulsion of colloidal silica to a W/O micro-emulsion of lithium and magnesium nitrate salts, a micro-emulsion of silica aggregates containing detached groups of the ceramic parent salts is prepared. The solid support (porous alpha-alumina) is put into... View full abstract»

  • Temperature-sensitive nanocapsules for methane storage

    Publication Year: 2009, Page(s):172 - 176
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (283 KB)

    A nanocapsule is investigated for methane storage purposes. The nanocapsule is a dasiabucky shuttledasia (or a nanopeapod) with a hole in its structure. The bucky shuttle has a diameter of a nanotube (10, 10) and is 180dasiaAdasia in length. A K@C60 1+ endohedral complex is encapsulated into the nanocapsule. Simulations are performed by a molecular dynamics method. The intern... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (288 KB)

    The flower-like tin disulphide (SnS2) microspheres have been synthesised by a facile solution-based route using polyethylene glycol 200 as the solvent and template. The products are characterised by X-ray diffraction, transmission electron microscopy and scanning electron microscopy. Experimental results show that the flower-like SnS2 microspheres with diameters around 2-5--m... View full abstract»
