Multiscale Modeling of Organic-Inorganic Semiconductor Materials: Opportunities and Challenges

Stevenson J., Saathoff J., Clancy P., Cornell University, US

Many of the most interesting new materials that show promise for solar photovoltaics, involve atomic species, like lead and selenium, that are non-traditional from the point of view of computational modeling. This poses a problem [...]

Fourier Transform Infrared Spectroscopy of Silicon Carbide Nanowires

Teker K., Abdurazik D., Istanbul Sehir University, TR

Silicon carbide is a wide band-gap semiconductor material with many superior properties, such as high electron mobility, high thermal conductivity, high mechanical strength, and high radiation resistance. These superior properties make SiC an excellent material [...]

Roll-to-roll application of photocatalytic TiO2 nanoparticles for printed functionality

Saarinen J.J., Valtakari D., Bollström R., Stepien M., Haapanen J., Mäkelä J.M., Toivakka M., Abo Akademi University, FI

We present here ultraviolet A (UVA) light controlled photocatalytic activity of roll-to-roll (R2R) deposited TiO2 nanoparticles on paper, board, and plastic films both for controlled wetting and oxygen sensors for modified atmosphere packages (MAPs). It [...]

Nanofabrication with Lanthanum Hexaboride (LaB6) for Nanoscale Vacuum Electronics

Mankin M.N., Pan T.S., Modern Electron, US

We present the first nano- and microfabrication of vacuum microelectronic components incorporating lanthanum hexaboride (LaB6), a refractory low work function material with high electron emissivity. We design novel fabrication processes which yield ultra-low fill factor [...]

Advances in Magnetohydrodynamic Molten Metal Jet Printing

Vader S., Vader Z., Vader S., Vader Z., Karampelas I.H., Furlani E.P., University at Buffalo (SUNY), US

At present, most metal 3D printing applications involve deposited metal powder sintering or melting under the influence of an external energy source such as a laser (e.g. Selective Laser Sintering (SLS) [1] and Direct Metal [...]

Formulation, characterization and applications of titanium dioxide, polyoxometalates and silver nanocomposites

Kumar Daima H., Amity University Rajasthan, IN

In the recent past, Titanium dioxide (TiO2), polyoxometalates (POMs) and silver (Ag) based nanomaterials have been employed for various biological and industrial applications. TiO2 possesses excellent photocatalytic activity; POMs are keggin ions with exceptional biomedical [...]

Novel electrospun PVA/Fe-MOF nanofibres as a super adsorbing material of lead ions in aqueous solution

Shooto N.D., Dikio E.D., Sikhwivhilu L., Wankasi D., VUT, ZA

In this study electrospun PVA nanofibres were functionalized with Fe-MOFs to synthesise a novel super adsorbing material. The synthesized material was characterized by scanning electron microscope (SEM), Fourier transform infrared (FTIR) and Thermogravimetric analysis (TGA). [...]

Nanocomposite dodecylsulfate-modified Mg-Al layered double hydroxide thin films deposited via laser technique

Vlad A., Birjega R., Matei A., Dumitru M., Dinescu M., Zavoianu R., Pavel O.D., Corobea M.C., National Institute for Lasers, Plasma and Radiation Physics, Romania, RO

Layered double hydroxides (LDHs), also known as hydrotalcites or anionic clays having a brucite-like structure are a class of host-guest materials, which can be described by the formula [M2+1-xM3+x(OH)2]x+(An-)x/n•mH2O where M2+ and M3+ are divalent [...]

Continuous Preparation of Polymer Nanocomposites for Applications in Novel Substrates, Multilayered Materials, and 3D Printing

Barry C., Kazmer D., Mead J., University of Massachusetts-Lowell, US

Polymer nanocomposites are composed of a nanofiller, such as nanoclay, carbon nanotubes, graphene, and nanosilver, in a polymer matrix. Depending on the choice of filler, these nanocomposites exhibit unique material properties, including improved barrier properties, [...]

New Powder Synthesis Technology: Cubic Nano Alumina

Fukuhara S., Tahara M., Miwa N., Ashitaka K., Tamai K., Morinaga H., Ogitani S., Fujimi Incorporated, JP

Alumina is chemically stable and excellent in hardness, heat resistance, and mechanical properties. That is the reason alumina is widely used as a structural material, an abrasive grain and a cutting tool. In general, alumina [...]
