Determination of the Solubility of Tin in Indium Oxide Using In Situ and Ex Situ X-ray Diffraction
G.B. González, T.O. Mason, J.S. Okasinski, T. Buslaps and V. Honkimäki

This team of researchers from the United States and France presents a novel approach to determine the thermodynamic solubility of tin in indium oxide via exsolution from tin-overdoped nano-ITO powders using high-energy synchrotron X-ray diffractiometry. The team reports structural results, including compositional phase analysis, atomic positions and lattice parameters. It also reports experimental complications that can lead to incorrect tin solubility values.

Synthesis and Characterization of Rutile Nanocrystals Prepared in Aqueous Media at Low Temperature
Linggen Kong, Inna Karatchevtseva, Mark Blackford, Ilkay Chironi and Gerry Triani

These Australian researchers synthesized rutile powder using a sol-gel process and Tyzor TE precursor in an aqueous solution at 40°C-50°C and characterized the microstructural evolution using several techniques. They report that the resulting powder was phase-pure rutile with a surface area of 144.7 square meters per gram, an average pore size of 24.9 nanometers and a pore volume of 0.66 cubic centimeters per gram. They also propose a reaction mechanism for the preferential evolution of rutile over amorphous or anatase polymorphs.

Damage Development in Confined Borosilicate and Soda-Lime Glasses
Kathryn A. Dannemann, Charles E. Anderson Jr., Sidney Chocron and James F. Spencer

This team of researchers from the Southwest Research Institute in Texas used borosilicate (Borofloat® 33) and soda-lime (Starphire®) glass to investigate the flow and failure behavior caused by compressive loading with confinement in order to study the damage process that occurs during projectile impact/penetration into transparent armor. The team proposes a damage mechanism.

Enhancement of Photoluminescence and Color Purity of CaTiO3:Eu Phosphor by Li Doping
Yun-Fang Wu, Yung-Tang Nien, Yi-Jhang Wang and In-Gann Chen

This Taiwan National Cheng Kung University research team synthesized red phosphors of Ca1-3/2xEuxLixTiO3 and Ca1-2xEuxLixTiO3 (0 < x ≤ 0.3) with high color purity using a solid-state method. The team reports that color coordinates approach the ideal red chromaticity values with increasing Eu3+ and Li+ contents.

CuInS2/N3 Co-Sensitized ZnO Nanorods with Improved Photovoltaic Properties for Solar Cells
Yabin Li, Zhifeng Liu, Chengcheng Liu, Jing Ya, Lei E, Wei Zhao, Qian Chen and Junyu Bai

These researchers from China’s Tianjin Institute of Urban Construction used a solution reaction and ZnO nanorod arrays to synthesize ZnO/CuInS2 arrays. N3 dye was sequentially assembled on the arrays to construct a cascading cosensitized nanomaterial for use as a photoanode of a solar cell. The researchers report a 24.8 percent enhanced efficiency compared with material single sensitized by N3 because of abundant light harvesting, higher chemical instability in acid dye, fast injection and transmission velocity, and the slowdown recombination of photo-excited electrons.

Processing and Properties of Textured Potassium Strontium Niobate (KSr2Nb5O15) Ceramic Fibers-Texture Development
Sedat Alkoy and Sinan Dursun

These researchers from Turkey fabricated highly textured KSr2Nb2O15 fibers using an alginate gelation method and templated grain growth using acicular template particles prepared by molten salt synthesis. They report that they obtained a maximum degree of orientation of 0.95 (measured by Lotgering factor) and a grain orientation distribution 0.28 (measured by rocking curve analysis).
