Thermal conductivity model for polymer/Boron Nitride nanocomposite considering air void content

Park S.Y., Kim J.H., Shin M.W., Yonsei University, KR

Polymer/Boron Nitride (BN) nanocomposite is promising interfacial material for cooling of electronic systems. It is important to determine percolation threshold when it practically uses in the industry. But, the exact prediction with existing model is [...]

Preparation of a Flexible Microfluidic Chip Device with MMT/PEG Hydrogel Nanocomposite Molds for Nanobio-chip Applications

Kim G.M., Kim Y.H., Woo Y., Jung J., Choi J-R, Kim G.M., Kim Y.H., Kang B.K., Sohn J-W, Daegu-Gyeongbuk Medical Innovation Foundation, KR

A thin and flexible microfluidic chip device using microstructured montmorillonite (MMT) reinforced polyethylene glycol (PEG) nanocomposite molds has been presented to apply miniaturized nanobio-chips. Biocompatible PEG hydrogel with 1-2 wt.% of MMT was used to [...]

Non-conductive ferromagnets based on core double-shell nanocomposites for radio-electric applications

Takacs H., Viala B., Hermán V., Tortai J.-H., Duclairoir F., Alarcon Ramos J., Jouneau P.-H., Okuno H., Tallec G., CEA, FR

We report a novel flexible nanotechnology for consumer product engineering as a complementary approach from solid-state manufacturing techniques based on metallic nanoparticles and graphene chemistries. We describe two chemical routes for producing closely-packed disordered assemblies [...]

Effect of the Consolidation Techniques on the Mechanical Properties of Nanocrystalline Ti55C45 Powders Prepared by Mechanically Induced Self-Propagating Reaction

Sherif El-Eskandarany M., Al-Hazza A., Al-Hajji L., Shaban E., Al-Rowayeh A., Kuwait Institute for Scientific Research, KISR, KW

A single phase of NaCl-type TiC was obtained after 5 h of ball milling. To decrease the powder and grain sizes, the synthesized material was subjected to further ball milling time. The powders obtained after [...]

Attenuation of Disturbances Using Packed Bed of Nanoparticles

Asif M., Ali S.S., Hameed B.H., King Saud University, SA

The attenuation of disturbances and shocks is quite important as well as challenging task in a variety of situations. In the present work, the attenuation of disturbance through a packed bed of ultrafine nano-powder that [...]

MgO Nanoparticles for the Removal of Reactive dyes from Wastewater

Jamil N., Mehmood M., Lateef A., Nazir R., Ahsan N., University of the Punjab, PK

The quality of water reservoirs are under threat due to over exploitation and disposal of untreated wastewater. Throughout the world, diverse industrial operations and processes are contaminating all the spheres of environment. Amongst these, textile [...]

Development and Characterization of an aqueous dispersion based nano zinc oxide for cosmetic application in sunscreens

Perez-Rodriguez F., Acosta-Gonzalez G., Gutierrez-Antonio J., Aguilera-Bustos M., Acosta-Armenta L., Nanomateriales, MX

Development of an additive based nanostructured zinc oxide nano through a grinding process1 and physicochemical surface functionalization allows the formation of a stable aqueous dispersion having high solids and thus, high capacity for absorption of [...]

Antibacterial effect of zinc oxide nanoparticles against water borne bacteria

Rubab F., Chaudhary M.F., Butt N.M., Preston University, Islamabad Campus, PK

We have investigated antibacterial properties of zinc oxide nanoparticles against gram negative bacteria isolated from drinking water. We isolated and identified Escherichia coli, Serratia marcescens, Enterobacter cloacae and Aeromonas hydrophila. Our results showed zinc oxide [...]

Detection and degradation of environmental pollutants based on Fe3O4@Au nanoparticles as surface enhanced Raman scattering (SERS) substrates

Du J., Jing C., Chinese Academy of Sciences, CN

Ever since the surface-enhanced Raman scattering (SERS) effect was discovered, it has played a significant role in the field of vibrational spectroscopy and is now finding increasing use in high-profile applications. Recently, many catalytic-active SERS [...]

Ultrasensitive mercury sensors based on graphene decorated with nanoparticles

Ayesh A.I., Qatar University, QA

In this work we present a highly sensitive and selective sensor for detection of mercury traces in water. The sensor is constructed by creating interdigitated metal electrodes on a graphene layer placed on SiO2/Si substrate. [...]
