Using polymer templated nanoporous materials to improve performance in electrochemical pseudocapacitors and batteries

Block-copolymer templating of inorg. frameworks provides a powerful route to produce periodic nanoporous materials with well-defined nanoscale architectures, controlled porosity, and high surface area. Such control is important for batteries and pseudocapa ...

Accumulation-mode gate-all-around Si nanowire nMOSFETs with sub-5 nm cross-section and high uniaxial tensile strain

Mihai Adrian Ionescu, Jean-Michel Sallese, Didier Bouvet, Wladyslaw Grabinski, Mohammad Najmzadeh

In this work we report dense arrays of accumulation-mode gate-all-around Si nanowire nMOSFETs with sub-5 nm cross-sections in a highly doped regime. The integration of local stressor technologies (both local oxidation and metal-gate strain) to achieve ⩾2.5 ...

Ordered Arrays of Size-Selected Oxide Nanoparticles

Luca Gragnaniello

A bottom-up approach to produce a long-range ordered superlattice of monodisperse and isomorphic metal-oxide nanoparticles (NP) supported onto an oxide substrate is demonstrated. The synthetic strategy consists of self-assembling metallic NP on an ultrathi ...

UV-curable epoxy primer for adhesion between metallic oxides and thermoplastic polyurethane

Véronique Michaud, Basile Golaz

We report results on the development of an innovative fast-curing coupling method using a UV-curable epoxy primer based on a cycloaliphatic di-epoxide resin. The materials to bond are metallic wires and a thermoplastic polyurethane matrix. The curing kinet ...

Correlation between anionic substitution and structural properties in AlCr(OxN1-x) coatings deposited by lateral rotating cathode arc PVD

Alireza Karimi, Hossein Najafi

The influence of oxygen content on the properties of cathodic arc-deposited AlCr(OxN1-x) coatings has been studied. All samples were prepared in a nitrogen-rich mixture of N-2 and O-2 at 550 degrees C using lateral rotating arc cathodes (LARC) technology t ...

Fabrication of homogeneous titania/MWNT composite materials

László Forró, Arnaud Magrez, Jin Won Seo, Klara Hernadi

MWNT/titania nanocomposites were prepared by an impregnation method and subsequent heat treatment at 400 degrees C. Precursor compounds such as titanium (IV) propoxide and titanium (IV) ethoxide were used to cover the surface of CNTs under solution conditi ...

Preparation of homogeneous titania coating on the surface of MWNT

László Forró, Duncan Thomas Lindsay Alexander, Jin Won Seo, Klara Hernadi

Preparation of homogeneous and stable inorganic coatings on the surface of multi-wall carbon nanotubes (CNTs) was studied. Precursor compounds such as titanium (IV) bromide and titanium (IV) chloride were used to cover the surface of CNTs under either solv ...

Tuning optical modes in slab photonic crystal by atomic layer deposition and laser-assisted oxidation

Laurent Balet

The authors experimentally investigate the effects of atomic layer deposition (ALD) and laser-assisted oxidation on the optical modes in GaAs L3 photonic crystal air-bridge cavities, using layers of InAs quantum dots as internal light source. Four distinct ...

Combinatorial High-Vacuum Chemical Vapor Deposition of Textured Hafnium-Doped Lithium Niobate Thin Films on Sapphire

Paul Muralt, Patrik Willi Hoffmann, Silviu Cosmin Sandu, Ali Dabirian, Yury Kuzminykh, Estelle Wagner, Scott Harada, Giacomo Benvenuti

Combinatorial high-vacuum chemical vapor deposition (HV-CVD) was used to identify the conditions required to obtain hafnium-doped lithium niobate thin films on sapphire {001} substrates. Niobium tetraethoxydimethylaminoethoxide (Nb(OEt)(4)(dmae)), lithium ...

Properties of nanocomposite film combining hard TiN matrix with embedded fullerene-like WS2 nanoclusters

Silviu Cosmin Sandu

We have developed hard self-lubricant coatings combining a hard matrix (TiN) and a self-lubricant phase in the form of inorganic-like WS2 fullerene. The nanoparticles were injected from the preparation chamber directly to the sample surface during reactive ...
