Quantitative Analysis of Oxidation State in Cerium Oxide Nanomaterials

Sims C.M., Maier R.A., Johnston-Peck A.C., Gorham J.M., Hackley V.A., Nelson B.C., National Institute of Standards and Technology, US
Of the many engineered nanomaterials being incorporated into our society, cerium oxide (ceria, CeO2-x) based nanomaterials (NMs) are receiving increased attention due to their unique chemical properties and vast number of current and potential applications [...]

Investigation of the MgO absorbate and the MgO/Fe on GaAs(001) surface by means of XPS and XPD

Handschak D., Schönbohm F., Lühr T., Keutner C., Berges U., Westphal C., TU Dortmund, DE
We report a combined high-resolution photoemission and photoelectron diraction investigation of a magnesium oxide adsorbate on an Fe surface grown on a GaAs(4x2)-reconstructed substrate. MgO is an appliciable insulator in magnetic tunnel junctions (MTJ) based [...]

Novel Organofunctional Silane Coatings on Silica-Coated Ti

Matinlinna J.P., Tsoi J.K.H., The University of Hong Kong, HK
This in vitro study characterizes a developed novel silane system method to produce coatings on Ti. Hydrophobic coatings are needed in prosthetic dentistry to promote durable adhesion between luting resin cements and coated Ti surfaces. [...]

The Effect of Growth Temperature on Aluminum Nanocrystal Embedded AlOxNy for Non-Volatile Memory

Chen N.H., Hsieh P-H, Huang F.S., Huang S-J, Huang F.S., Huang S-J, National Tsing Hua University, TW
The aim of this paper is to present a aluminum-based nonvolatile memory of Al2O3 (28 nm)/ Al-rich Al0.54O0.42N0.04 (22 nm)/ Al0.44O0.38N0.18 (3 nm) layered structure on SiO2 (2 nm)/ n-Si by a simple rapid thermal [...]

Effect of C Content and Calcination Temperatures on the Characteristics of C-doped TiO2 Photocatalyst

Chen F.Y., Lin Y.-T., National Chung Hsing University, TW
This study is about the effect of carbon content and calcination temperatures on the characteristics of C-doped TiO2 prepared by sol gel method. Synchrotron radiation with high energy and resolution was applied for the identification [...]

Tuning the electronic and chemical surface properties of graphane combining alkali deposition and low-energy ion irradiation

Heim B., Allain J.P., Zemlyanov D., Taylor C.N., El-Atwani O., Purdue University, US
The presence of defects in graphene due to thin-film processing can lead to alterations of its electronic properties. Tuning of graphene’s electronic properties could be achieved through control of thermal deposition of alkaline dopants (e.g. [...]

Pulsed laser co-deposition of titania with Fe: chemistry, local atomic structure, and light-dependent magnetic properties

Negrila C., Logofatu C., Socol G., Macovei D., Teodorescu C.-M., National Institute of Materials Physics, RO
Transition metal doped titania has been revealed as a promising diluted magnetic semiconductor. We report the synthesis of TiO2:Fe and of mixed Ti and Fe oxides by pulsed laser deposition. The obtained layers were analyzed [...]

Durability of Supported CoOx Nanoparticles for Low-Temperature CO Oxidation

Kim K.H., Kim M.H., Kim K.H., Kim M.H., Ham S.W., Daegu University, KR
Please see the attached PDF file.

Conductance Enhancement of Nanoparticulate Indium Tin Oxide Layers Made by Printing Technique

Gross M., Maksimenko I., Faber H., Linse N., Wellmann P.J., University Erlangen-Nuremberg, DE
To improve their conductance we applied several treatments on nanoparticulate indium tin oxide (In2O3:Sn, ITO) layers: post bake, infiltration by an ITO precursor solution with subsequent sol-gel transformation into ITO, treatment with etching agents as [...]

Synthesis and X-ray photoelectron spectroscopy studies of poly(vinyl pyrrolidone) capped gold nanoparticles in a hybrid composite

Mishra A., Tripathy P., Ram S., Fecht H-J., Indian Institute of Technology, IN
Gold nanoparticles are synthesized by direct reduction of an aqueous solution of the metal salt with a surface regulating polymer N-polyvinyl pyrrolidone (PVP), which bind on the gold surface, insulate the particles from Au3+ and [...]
