New Nanocomposites – Controlled Capture of Nanoparticles in Scrolled Nanosheets

Adireddy S., Yao Y., Vargas J.M., Spinu L., Wiley J.B., University of Neworleans, US

The ability to encapsulate linear nanoparticle chains in scrolled nanosheets is an important advance in the formation of nanocomposites. Recent work in our group resulted in the in situ formation of peapod-like structures based on [...]

Preparation of Calcium Zirconate –Silica nano composite and consideration of thermal, electrical and photocatalitical properties

Kermani N., Kargar Razi M., Azad University Tehran North Branch, IR

In this research, Calcium Zirconate–Silica nanocomposite was synthesized and its thermal, electrical constant and photocatalitical properties were evaluated. For preparation of CaZrO3/SiO2, nano powder was synthesized by sol-gel method then was calcinated at 700- 1000 [...]

Facile in-situ combustion synthesis of TiC reinforced aluminum matrix composites

Nabawy A.M., Khalil K.A., Al-Ahmari A.M., King Saud University, SA

Using high frequency induction heat-assisted combustion synthesis (HFIHACS) as a facile manufacturing methods followed by combustion in tube furnace under inert gas, composites of TiC reinforced aluminum matrix have been in-situ synthesized directly from elemental [...]

The Synthesis and Characterisation of Photocatalytic Silver/Silver Halide Nanocomposites of Kraft Paper Fibres and Calcium Silicate

Tate E.W., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

Recently it has been shown that hybrid silver/silver halide nanoparticles exhibit interesting photocatalytic properties, and are known plasmonic photocatalysts. Enhanced photostability and photocatalysis are observed in the nanoparticles due to the surface plasmon resonance of [...]

Aulana and NgaPure : Novel Nanogold Coloured and Antimicrobial Nanosilver Woollen Textiles: The Journey of Discovery, the Nanoscience and Pathway to Commercialisation

Johnston J.H., Noble Bond Ltd, NZ

Aulana and NgaPure products innovatively combine the nanoscience of gold and silver with their affinity for sulfur in cystine amino acids of wool fibres in a synergistic way, to nanofunctionalise wool and produce a boutique [...]

Self-assembled Magnetic Silica Nano-rods and Micro-platelets as smart reinforcements for polymer-composites

Furlan M., Lattuada M., University of Fribourg, CH

In this work, we propose a new versatile self-assembly technique to obtain large quantities of silica-based magnetic nano and micro-rods and of magnetic microplatelets, which can be easily oriented by weak magnetic fields. Our process [...]

Mechanical Properties of Reduced Graphene Polymer Composites

Xu P., Panchapakesan B., University of Louisville, US

In this paper, we report load transfer and mechanical properties of chemically derived single layer graphene (SLG) as reinforcements in poly (dimethyl) siloxane (PDMS) composites. Shear mixing reduced graphene sheets in polymers resulted in a [...]

Asphalt bitumen modified with carbon nanotubes

Boyer L., Barrera E.V., Rice University, US

We have introduced carbon nanotubes into asphalt bitumen (paving asphalt with no stone or sand aggregate) to investigate the effect on (1) strength, (2) viscoelasticity, and (3) exposure to microwave radiation.

Challenges and Opportunities in the Scale-up of Cellulose Nanofibril Production

Gardner D.J., University of Maine, US

Technologies to produce cellulose nanofibrils via either mechanical means (CNF) or chemical means (cellulose nanocrystals (CNC)) have improved dramatically over recent years and a limited number of companies and research labs can produce cellulose nanofibrils [...]

Composites with Multi-Walled Carbon Nanotubes

McAndrew T.P., Havel M., Korzhenko A., Delprat P., Arkema Inc., US

Multi-walled carbon nanotubes are of great interest – primarily based upon their electrical and mechanical properties. The main application is in polymer composites – where at low concentrations they provide substantial improvements in electrical and [...]
