    Structural, mechanical and electrical-contact properties of nanocrystalline-NbC/amorphous-C coatings deposited by magnetron sputtering2011In: Surface & Coatings Technology, ISSN 0257-8972, E-ISSN 1879-3347, Vol. 206, no 2-3, p. 354-359Article in journal (Refereed)
    Abstract [en]

    Niobium-carbide nanocomposite coatings with a carbon content varying from 43 to 64 at.% were deposited by dual DC magnetron sputtering. X-ray diffraction, x-ray photoelectron spectroscopy and electron microscopy showed that all coatings consisted of nanometer sized NbC grains embedded in a matrix of amorphous carbon. Mechanical properties and electrical resistivity showed a strong dependency on the amount of amorphous carbon (a-C) and NbC grain size in the coating. The highest hardness (23 GPa), elastic modulus (295 GPa) and the lowest resistivity (260 mu Omega cm) were measured for the coating with about 15% of a-C phase. Contact resistance measurements using a crossed cylinder set-up showed lowest contact resistance for the coating containing 33% a-C (140 mu Omega at a contact force of 100 N), which is comparable to a Ag reference (45 mu Omega at a contact force of 100 N). Comparison with TiC-based nanocomposites studied under similar conditions showed that the Nb-C system has less tendency to form a-C and that lowest contact resistance is obtained at comparable amounts of a-C phase in both material systems (33% for Nb-C compared to 35% for Ti-C). With these good electrical contact properties, the Nb- C nanocomposites can be considered as a potential material for electrical contact applications.

    Lithium Insertion into Vanadium Oxide Nanotubes: Electrochemical and Structural Aspects2006In: Chemical of Materials, Vol. 18, no 2, p. 495-503Article in journal (Refereed)
    Abstract [en]

    The electrochemical and structural aspects of lithium insertion into vanadium oxide nanotubes have been studied. Structural changes, induced as lithium was inserted between the vanadium oxide layers, were followed by in situ synchrotron X-ray diffraction recorded during potential steps. Two separate processes were identified: a fast decrease of the interlayer distance followed by a slow two-dimensional relaxation of the intralayer vanadium oxide structure. The nanotubes were synthesized using crystalline V2O5 as a precursor, instead of the normally used vanadium alkoxide, which produced a more cost-effective material with similar performance. Electrochemical measurements showed that surface processes, i.e., charge transfer and/or ohmic drop, were rate-controlling, as can be anticipated for the thin layer electrochemical conditions used in this study.

    Size or polarisability effects? A comparative study of TlCu7S4 and TlCu7Se42001In: JOURNAL OF ALLOYS AND COMPOUNDS, ISSN 0925-8388, Vol. 314, no 1-2, p. 114-123Article in journal (Refereed)
    Abstract [en]

    The room temperature structures of the tetragonal compounds TlCu7S4 and TlCu7Se4 have been reinvestigated on various fronts, by experiment and theoretical calculations. Neutron powder diffraction data have been analysed by Rietveld profile refinement and Reverse Monte Carlo modelling. Both approaches show substantial disorder on the copper site that corresponds to 25% vacancies in the common crystallographic description, and more so inthe thiocuprate than in the selenocuprate.

    On the Existence of Transition-Metal Fullerides: Deposition and Characterization of TixC601998In: Chemistry of Materials, Vol. 10, no 4, p. 1184-1190Article in journal (Refereed)
    Abstract [en]

    Titanium fulleride films (TixC60) were prepared by coevaporating Ti and C60 onto moderately heated substrates (~100 C) in an ultrahigh vacuum system. The TixC60 films were all amorphous according to X-ray diffraction and exhibited a gray, metallic luster different from the brown color of pristine C60. The compound also appeared to be metallic or semiconducting as no charging was observed in X-ray photoelectron spectroscopy (XPS) in contrast to analyses of pure C60. XPS of the films showed a maximum titanium content of about 5.3-5.5 at. % (Ti~3.5C60). For higher titanium contents, carbide formation was observed. The XPS analyses also showed binding energy shifts and line broadening effects consistent with the formation of chemical bonds between Ti and C60. Raman spectroscopy showed a softening of the Ag(2) mode upon Ti incorporation (-4 cm-1/Ti atom) which is consistent with a partial charge transfer from Ti to C60. The TixC60 films oxidized immediately upon air exposure. However, XPS and Raman spectroscopy show persistent differences from pristine C60 which might indicate that another phase, TixOyC60, is formed upon oxidation.

    Chemical vapour deposition of molybdenum carbides using C60 as a carbon source1997In: Thin Solid Films, Vol. 293, no 1-2, p. 133-137Article in journal (Refereed)
    Abstract [en]

    Single-phase molybdenum carbide films were deposited on sapphire by CVD from a C60/MoCl5/H2 gas mixture. Mo2C could be grown at substrate temperatures of 600 and 800°C using total pressures of 100 and 10 Torr, respectively. Metastable δ-MoC1−x was also deposited at 800°C by lowering the total pressure to 2 Torr. For a constant mass flow of carrier gas, a high total pressure resulted in an increased growth rate of Mo2C at 600°C, whereas a low total pressure favoured the growth of δ-MoC1−x at 800°C. The films were lustrous and showed good adhesion to the substrate. Resistivities of 56-140 μΩ cm were measured for the single-phase films.

    Electrochemical techniques for lab-on-a-chip applications2005In: Analyst, Vol. 130, p. 1-14Article in journal (Refereed)
    Abstract [en]

    During the last few years there has been a rapid increase in the use of electrochemical reactions in lab-on-a-chip devices. This development, which has so far mainly focussed on electrochemical detection in chip-based capillary electrophoresis, can be explained by the fact that electrochemical techniques and devices are particularly well-suited for inclusion in lab-on-a-chip systems. The most important reason for this is that the required electrodes can readily be manufactured and miniaturised without loss of analytical performance using conventional microfabrication methods. In this Research Highlight article, the developments during the last three years concerning electrochemical techniques for lab on-a-chip applications are discussed, with particular focus on emerging electrochemical methods for sample clean-up and preconcentration, electrochemical derivatisation and electrochemical detection in chip-based capillary electrophoresis.

    Toward Flexible Polymer and Paper-Based Energy Storage Devices2011In: Advanced Materials, ISSN 0935-9648, E-ISSN 1521-4095, Vol. 23, no 33, p. 3751-3769Article in journal (Refereed)
    Abstract [en]

    All-polymer and paper-based energy storage devices have significant inherent advantages in comparison with many currently employed batteries and supercapacitors regarding environmental friendliness, flexibility, cost and versatility. The research within this field is currently undergoing an exciting development as new polymers, composites and paper-based devices are being developed. In this report, we review recent progress concerning the development of flexible energy storage devices based on electronically conducting polymers and cellulose containing composites with particular emphasis on paper-based batteries and supercapacitors. We discuss recent progress in the development of the most commonly used electronically conducting polymers used in flexible device prototypes, the advantages and disadvantages of this type of energy storage devices, as well as the two main approaches used in the manufacturing of paper-based charge storage devices.

    Ultrafast All-Polymer Paper-Based Batteries2009In: Nano letters (Print), ISSN 1530-6984, E-ISSN 1530-6992, Vol. 9, no 10, p. 3635-3639Article in journal (Refereed)
    Abstract [en]

    Conducting polymers for battery applications have been subject to numerous investigations during the last two decades. However, the functional charging rates and the cycling stabilities have so far been found to be insufficient for practical applications. These shortcomings can, at least partially, be explained by the fact that thick layers of the conducting polymers have been used to obtain sufficient capacities of the batteries. In the present letter, we introduce a novel nanostructured high-surface area electrode material for energy storage applications composed of cellulose fibers of algal origin individually coated with a 50 nm thin layer of polypyrrole. Our results show the hitherto highest reported charge capacities and charging rates for an all polymer paper-based battery. The composite conductive paper material is shown to have a specific surface area of 80 m(2) g(-1) and batteries based on this material can be charged with currents as high as 600 mA cm(-2) with only 6% loss in capacity over 100 subsequent charge and discharge cycles. The aqueous-based batteries, which are entirely based on cellulose and polypyrrole and exhibit charge capacities between 25 and 33 mAh g(-1) or 38-50 mAh g(-1) per weight of the active material, open up new possibilities for the production of environmentally friendly, cost efficient, up-scalable and lightweight energy storage systems.

    Growth and some properties of Sc2AlB6 crystal obtained from the solution in aluminium melt2004In: Journal of Solid State Chemistry, Vol. 177, no 2, p. 547-550Article in journal (Refereed)
    Abstract [en]

    Crystals of Sc2AlB6 were grown using scandium oxide and elemental boron as starting materials in a self-component aluminum solution under an argon atmosphere. The growth conditions for obtaining single crystals of relatively large size were investigated. Sc2AlB6 single crystals were obtained in the form of prisms extending in the b-axis direction. The largest Sc2AlB6 crystals prepared had maximum dimensions of about 0.4×0.4×4.2 mm3. The values of the Vickers microhardness and the electrical resistivity of Sc2AlB6 crystals are 12.7±0.8 GPa and 43±8 cm, respectively. The oxidation of Sc2AlB6 crystals starts at about 773°C, and the weight gain after TG determination is 12.9 mass% at 1200°C. The oxidation products of Sc2AlB6 crystals could not determined.

    Initial growth of hexagonal and cubic boron nitride: A theoretical study2003In: Physical Review B, Vol. 68, p. 075411-Article in journal (Refereed)
    Abstract [en]

    Adsorption of NH3 and BBr3 (and their decomposed fragments) onto B and N sites of c-BN(111) and h-BN(100), has been theoretically investigated using DFT calculations under periodic boundary conditions. The purpose was to study the adsorption processes of the precursors during gentle deposition of BN thin films in order to find prerequisites for ideal growth of c-BN, and to simultaneously discriminate h-BN growth. The present results show that adsorption of NH3, NH2, NH, N, BBr3, BBr2, BBr, and B (with three exceptions) is exothermic to either the B or N sites of c-BN(111) and h-BN(100), respectively. The exceptions include adsorption of NH3 to the N site of either the cubic surface or the hexagonal edge, as well as adsorption of BBr3 to the B-rich surface of c-BN. In opposite to all other combinations studied, adsorption of NH3 and BBr3 was found to preferably lead to an ideal growth of c-BN.

    Laser-Assisted Atomic Layer Deposition of Boron Nitride Thin Films2005In: Chemical Vapor Deposition, Vol. 11, p. 330-337Article in journal (Refereed)
    Abstract [en]

    Boron nitride thin films have been grown by both laser-assisted, and conventional atomic layer deposition (LALD/ALD) at temperatures in the range 250-750 °C. Both the NH3 and BBr3 precursors were appreciably dissociated by the ArF excimer laser, and up to 600 °C, the growth rate was 100 % higher for the LALD process than for ALD. The films consisted of hydrogen-terminated turbostratic BN grains. H2 was theoretically found to bind as strongly as BBrX and NHX (X = 0-2) to hBN(100) edges. The fresh films were stoichiometric with respect to B and N, and contained low degrees of contamination, but oxidized easily in air.

    On-Chip Electric Field Driven Electrochemical Detection Using a Poly(dimethylsiloxane) Microchannel with Gold Microband Electrodes2008In: Analytical Chemistry, ISSN 0003-2700, E-ISSN 1520-6882, Vol. 80, no 10, p. 3622-3632Article in journal (Refereed)
    Abstract [en]

    An external electric field driven in-channel detection technique for on-chip electrochemical detection in micro fabricated devices is described based on a microfluidic system containing an array of 20 microband electrodes. It is shown that an external electric field induces a potential difference between two gold microband electrodes in a poly(dimethylsiloxane) (PDMS) microchannel, and that this enables the electrochemical detection of electroactive species such as ascorbic acid and Fe(CN)64−. The results, which are supported by simulations of the behavior of the microband electrodes in the microfluidic system, show that the induced potential difference between the electrodes can be controlled by altering the external electric field or by using different microbands in the microband array. As the obtained currents depend on the concentrations of electroactive species in the flowing solution and the detection can be carried out anywhere within the channel without interference of the external electric field, the present approach significantly facilitates electrochemical detection in capillary electrophoresis. This approach consequently holds great promise for application in inexpensive portable chip-based capillary electrophoresis (CE) devices.

    Liquid DMSO has been investigated by means of X-ray and neutron diffraction, quantum-chemical calculations and molecular dynamics (MD) simulations. A new analytical all-atom pair potential for DMSO-DMSO interactions was developed from quantum-chemical calculations and employed in the simulations. The MD-derived total structure function agrees favourably with those obtained from the X-ray and neutron diffraction experiments. An analysis of the local structure shows a rather unstructured liquid with a slight for antiparallel ordering of the S-O dipoles.

    Initial Growth of BN on Diamond Substrates: A Theoretical Approach2010In: The Journal of Physical Chemistry C, ISSN 1932-7447, E-ISSN 1932-7455, Vol. 114, no 26, p. 11448-11455Article in journal (Refereed)
    Abstract [en]

    Cubic boron nitride, c-BN, is a very interesting material due to its extreme properties of which some are comparable, or even superior, to diamond. Unfortunately, there are severe problems with the vapor phase synthesis of c-BN, which makes it very important to investigate the possibility for new growth pathways. The choice of substrate has been experimentally found to be decisive for an ideal growth of c-BN. Diamond is a material that has been found to be a good substrate for growth of c-BN directly onto the substrate. By using quantum mechanical density functional theory (DFT) under periodic boundary conditions, the details in the layer-by-layer formation of BN onto diamond (100) has been investigated in the present study. The prerequisites for an initial growth of c-BN (100) have been studied by adding the alternative B and N layers sequentially and calculating the resulting interfacial binding strengths and geometrical structures. For the situation with one monatomic layer on diamond, the interfacial binding energy was calculated to be strongest for nitrogen heteroepitaxially positioned onto diamond (100). The individual atoms in a monatomic B adlayer did, however, not choose corresponding heteroepitaxial positions. When applying a second atomic layer of c-BN, two different models were initially constructed with different structural alignments with respect to the underlying diamond structure. One model was heterostructurally positioned on top of diamond (100), while the other model had the x-axis of the c-BN lattice aligned with the y-axis of the diamond lattice. For the situation with N attached to the diamond substrate, the heteroepitaxial adlayer structure stayed cubic as a result of the geometry optimization, while the other became amorphous-like. Both of these adlayer structures showed large interfacial binding strengths, but the amorphous-like structure became energetically the most stable one. On the contrary, a two-layer BN structure with B attached to the diamond surface did not show the same characteristics. It was only the initial heteroepitaxial BN lattice that resulted in a stable adlayer structure. It stayed cubic after the geometry optimization, with a large interfacial binding strength. The four-layer BN structure on diamond showed similar features.

    Structure Determination of the 4d Metal Diborides: A Quantum Mechanical Study2006In: The Journal of Physical Chemistry B, Vol. 110, no 11, p. 5367-5371Article in journal (Refereed)
    Abstract [en]

    Metal diborides (MB2) often have interesting thermal, mechanical, and superconducting properties. MgB2 was put into focus some years ago for its high transition temperature (39 K) in combination with its simple AlB2 structure. The boron structure in MB2 is assumed to be dependent on the electron transfer from the nearby positioned metal atoms. An electronic and structural comparison has been performed here for various initially planar and puckered transition-metal borides, using quantum mechanical density functional theory (DFT) calculations under periodic boundary conditions. In comparison to MgB2, the experimentally planar transition-metal diborides (ZrB2, NbB2, and MoB2) and the experimentally puckered ones (TcB2, RuB2, RhB2, and PdB2) have been examined. The results indicate that the energetic stability generally follows the experimentally obtained results. The metals that are less electronegative than boron donate electrons to boron, which in turn induce planar boron structures (graphitic-like). The metals that prefer to be planar donate more than one electron, while the trend for metals which favor puckered B structures is that they donate less than one electron per metal atom. Two donated electrons per metal atom (or very close to) will result in the most stable AlB2 structure.
