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 [...]
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 [...]
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.
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]

Since the production and utilities of NM have been growing exponentially we have decided to perform cell viability tests and mechanistic assays using different cell lines to assess the potential cytotoxicity of raw MWCNT, hydrophilic [...]
Synthesis of a light sensitive SWCNT/(Pb, Zn)-phosphate glass composite and it’s optical, light induced ESR, electronic and optoelectronic properties are reported. Absorption spectrum of SWCNTs of the composite differs from that of its film. Since [...]
Electrical parameters of the nano particle and carbon nano tube dispersed room temperature liquid crystalline materials 5CB and 6CHBT have been determined. Due to the dispersion, nematic to isotropic transition temperatures are highly affected. Threshold [...]

Fluorine-doped tin dioxide (FTO) thin films were deposited via ultrasonic spray pyrolysis directly on preheated polyimide (PI) - DuPont™ Kapton® polyimide flexible film substrates. All the FTO films deposited on PI substrates exhibited polycrystalline cassiterite [...]
Low cost conducting composites are required for bipolar plates of fel cells and battery electrodes. Polypropylene filled with graphite has been tried in the past but acceptable level of conductivity is reached only at high [...]
Nanodielectric materials become one of the new materials to play a sole role in sustainable and clean energy production, energy transportation, energy storage, and end usage in terms of energy storage capabilities due to the [...]
Gold nanoparticles (AuNP) embedded in mesoporous films of wide band gap semiconductors such as TiO2 are used for promising applications in solar cells, visible light-sensitive photocatalysts, and biosensors developed on the basis of the surface [...]
In this study, poly (p-aminophenol) film glassy carbon electrode (PPAP/GCE) was prepared by electrochemical polymerization and then Au-Ag nanoparticles created by electrochemical reduction from their solutions on the PPAP/GCE surface by cyclic voltammetry. The surface [...]
In this study, a poly (p-aminophenol) film (PPAP) and bimetallic nanoparticles modified polymer film electrodes (GCE), Au-Pt/PPAP/GCE, Au-Ag/PPAP/GCE, Au-Cu/PPAP/GCE were prepared by electrochemical techniques. The modified electrode surfaces were characterized using atomic force spectroscopy, scanning [...]
Nanocellulose fibers with the average diameter below 100nm were successfully obtained by a high shear microfluidizer. Their large surface area and nano-scale dimensions can lead to the emerging materials for reinforcements in polymer composites, differentiating [...]
