Structural and Optical Properties of Rare Earth Nano-Crystalline Oxides Embedded in Polymethyl Methacrylate

Tabanli S., Bilir G., Erdem M., Eryurek G., Istanbul Technical University, TR

In this study, various ratio and sizes of Nd2O3, Yb2O3 and Er2O3 nano-crystalline oxides were doped into polymethyl methacrylate (PMMA) host material. PMMA is an amorphous, thermoplastic polymer with an optical transparency region from 300 [...]

Laser precipitation of Eu and Yb codoped CaF2 nanocrystals on the surface of glass and emission characteristics

Kim D.S., Bae C-H, Lim K-S, Chungbuk National University, KR

We precipitated spatially selective Eu/Yb doped CaF2 nanocrystals on the surface of glass by CO2 laser irradiation. Because of low phonon energy of CaF2, we observed several times enhancements in down-shift emission under 365 nm [...]

The fracture behavior of SiC/Cu interpenetrating phase nanocomposites: A molecular dynamics study

Shadlou S., University of Saskatchewan, CA

Owing to their high strength, good abrasion resistance, low density, high melting temperature, and other interesting characteristics, ceramics have been extensively used in a wide range of industries [1]. However, one of the major drawbacks [...]

Innovative 3D Glass Fiber Metal Laminate

Lay T., Taheri F., ECI Limited, CA

Abstract A new assembled glass fiber metal laminate has a 3D E-glass fiber fabric core layer, which contains two bidirectional fabrics knitted together by vertical braided glass fiber pillars. Application of resin to core faces [...]

Luminiscent properties of europium-1,4-benzenedicarboxylate synthesized at room temperature

Loera-Serna S., Medina-Díaz J.C., Carmona Téllez S., Universidad Autónoma Metropolitana, MX

For many years the lanthanides have been considered as a series of complex, difficult to understand elements, however, research on them has not been adequate. In view of the many properties that have, in the [...]

The Perspective Applications of Graphene Oxide in the Construction Building Materials

Lu Z.Y., Li Z.J., Ma H.Y., the Hong Kong University of Science and Technology, HK

With the rapid development of the infrastructure, Portland cement has widely been used for building and construction. High performance cement and concrete is urgently needed to satisfy the high-rise buildings, marine tunnel and cross-sea bridges. [...]

Abstract: Thermoelectric properties of Nano structured Fe-Al Alloys. Susil k Putatunda and Shashank Nellikuppam. Wayne State University, Thermoelectric materials have emerged as very important engineering materials in recent years because of their ability to convert [...]

Release of Carbon Nanotubes from Nano-polymer Composites during Environmental Aging

Sahle-Demessie E., Han C., Zhao A., Wang J., Grecsek H., U.S. Environmental Protection Agency, US

Over the past two decades there has been a significant increase in commercial products incorporating engineered nanomaterials (ENM) that are now are used in electronic, cosmetics, automotive and medical products and in environmental applications. Although [...]

Aluminum Alloy: Nano Alumina Metal Matrix Composites Produced in an Innovative Way

Sommer A., Harrigan B., Curreli M., Gamma Technology LLC, US

Use of a proprietary process, patent applied for, enables us to implant individual nano alumina spheres into alminum alloy matrices via conventional powder metallurgy processing. No ball milling or other attrition process is required to [...]
