Effect of elevated hot temperatures on hybrid geopolymer synthesized with coal fly and bottom ashes

Kim H., Park C.W., University of Seoul, KR

Ordinary Portland Cement (OPC) concrete has been most widely used for construction materials although the strength deterioration of OPC concrete in high temperature has been pointed out as its inherent flaw. Considering that fire is [...]

Acid Electrolytes Effect on In-Situ Growth and Morphology of Polymer Nanowires in Microelectrode Devices

Mushfiq M., Alam M.M., InnoSense LLC, US

Conductive polymer (CP)-based nanostructured materials in thin films and nanowires have been utilized in numerous chemical sensor and biosensor applications.(1) Their beneficial attributes include: lightweight, large surface area, adjustable transport properties, chemical specificity, low cost, [...]

Effect of Ambient Pressure and Wire Parameters on Nanoparticle Characteristics during Microsecond Explosion of Aluminum Wire

Bai J., Shi Z., Wu Z., Jia S., Xi'an Jiaotong University, CN

Al nanoparticles have important applications in various fields, e.g., solid rocket propellant, explosives [1], electronics [2], detection of biomolecules [3], and enhancement of the properties of various nanocomposites [4-6], etc. Among various synthesis methods of [...]

SEM Characterization of Adipose Tissue Structure

Brimiene V., Skaudzius R., Misevicius M., Brimas E., Brimas G., Brimas E., Brimas G., Kareiva A., Vilnius University, LT

In this work the scanning electron microscopy (SEM) was used for the characterization of adipose tissue samples taken from volunteer obese patients. The adipose tissue was taken from 3 layers of adipose tissue (subcutaneous, preperitoneal [...]

Morphology and Size Control of Mesoporous ORMOSIL Particles

Jung G.I., Kim J-S, Koo S.M., Hanyang University, KR

Mesoporous ORMOSIL particles with tailored morphology and/or controlled size were prepared by a simple two-step process. The first step, synthesis of monodisperse ORMOSIL particles with multi-layered structure, involved a one-pot process in an aqueous solution [...]

ROS Evaluation for Series of CNTs Using the ESR Method and the Effects of CNT Mophology

Tsuruoka S., Takeuchi K., Koyama K., Endo M., Fujisawa K., Matsumoto H., Saito N., Usui Y., Porter D.W., Castranova V., Shinshu University, JP

Carbon nanotubes (CNTs) are becoming important materials in industry. It is a concern that CNTs may induce carcinogenic responses through pulmonary exposure. It has been recently reported1-6 that CNTs scavenge ROS depending on their morphology. [...]

New Functions of Polyolefin for Manipulated Iron Oxide Nanostructure Synthesis

Guo Z., He Q., Wei S., Lamar University, US

In this work, a novel function of PP-g-MA has been successfully explored. Specifically, PP-g-MA has been selected to replace the conventional fatty acid surfactants to fabricate stable iron oxide colloids. The fabrication process was carried [...]

Enhancement of photoelectrochemical and optical characteristics using a TiO2 nanoparticles interlayer in MEH-PPV heterojunction devices

Habelhames F., Girtan M., Manole A., Lamiri L., Zerguine W., Nessark B., Univesité Ferhat Abbas, DZ

In this work, MEH-PPV+TiO2 composite material was prepared by incorporation of titanium oxide nonoparticles (TiO2) into poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) polymer matrix and deposited by spin coating on glass and indium thin oxide (ITO) substrates. The absorbance [...]
