Effect of surface reconstruction on the growth of self-assembled Ag nanostructures on Si(111) surfaces

Goswami D.K., Indian Institute of Technology Guwahati, IN

In this work, we have shown that how buried interface structure of Si(111) surface influence the growth of Ag nanostructure growth. Electronic growth modes for Ag on Si(111)-7x7 surface can only be observed if the [...]

Magnetic Nano-Structures Growing by Laser Ablation Deposition

Allocca L., Bonavolontà C., Morone A., Valentino M., Verrastro M.F., Viggiano V., CNR, IT

Results of SmCo nanostructures growing by laser ablation deposition are presented. The magnetic nanostructures are deposited on Silicum (111) and on polymer makrolon substrates. The laser ablation magnetic nanostructures properties are performed using electron scanning [...]

Development of the high performance GFRP with multiwall carbon nanotubes

Tarumoto N., Hodogaya chemical Co., Ltd, JP

Owing to the structural and mechanical properties of multiwall carbon nanotubes (MWCNTs), composites of MWCNTs are studied. However there is are few reports describing that MWCNTs without chemical modification is effective to mechanical properties of [...]

Development of high performance MWCNTs-dispersed-media

Tarumoto N., Hodogaya chemical Co., Ltd, JP

Owing to the superior structural, electrical and mechanical properties of carbon nanotubes, many potential applications, such as electric conductive plastics, electromagnetic absorber, heater, lithium ion battery, heat sink and high strength composites have been proposed. [...]

Attachment of Quantum dots and gold nano particles on ZnO nanorods and nanotubes

Hari P., Seay J., Liang H., The University of Tulsa, US

ZnO nanorods grown by hydrothermal technique are of great interest for potential applications in photovoltaic and optoelectronic devices. In this study we investigate the Optimization of the optical absorption properties by a wet chemical bath [...]

siRNA Delivery Using Biodegradable Nanoparticles for Breast Cancer Therapy

Abbasi S., Arghya P., Afshan K., Prakash S., McGill University, CA

Polyethylenimine (PEI)-coated human serum albumin (HSA) nanoparticles form suitable biocompatible carriers for therapeutic molecules. Small interfering RNA (siRNA) molecules have suggested great promise as a future therapy for breast cancer. In order to overcome the [...]

Preparation of Ag/TiO2/bamboo charcoal composite based on chemical and electrochemical synthesis: characterization and antibacterial study

Pookboonmee S., Laohhasurayotin K., National Science and Technology Development Agency, TH

A combined function of photocatalysis, antibacterial, and adsorption was introduced as a composite powder in the form of Ag/TiO2/BC. The powder was characterized by SEM, TEM, and XRD for confirmation of the obtained product. The [...]

A Study on Fabrication of Cellulose Nanofibers in Water

Kim K-Y, Jeong W.-Y., Lim D.-Y., Korea Institute of Industrial Technology, KR

Cellulose nanofibers (CNFs) were successfully fabricated by fibrillation of wood pulp cellulose into submicron and/or nanoscale nanofibers with a microfluidizer in water solution. CNFs have the great potential as reinforcing materials for polymeric composite materials. [...]

Fabrication and Characterization of pH-Responsive, Nanoparticle-Attached Porphyrins for Singlet Oxygen Production

Li W., Courtney S., Gandra N., Ellis E.D., Tiyyagura P.T., Gao R., Jackson State University, US

The goal of this work was to understand if singlet oxygen (1O2) production from an immobilized dye could be regulated directly on support media such as titania and silica. Two types of pH- responsive, nanoparticle-attached [...]

Role of Hard Segment Induced Nanosized Domain on Concentrated Solutions and Bulk Properties

Lem K.W., Lee D.S., Haw J.R., Song G.S., Curran S., Sund S., Iqbal Z., Brumlik C., Konkuk University, KR

When a film is cast from solution, the volume fraction of polymer in the film increases with increasing drying temperature and/or time. Its viscoelastic behavior transitions from more viscous (where G” > G’) in dilution [...]
