Maghear A., Cernat A., Cristea C., Marian A., Marian I.O., Marian A., Marian I.O., Săndulescu R., Iuliu Hatieganu University of Medicine and Pharmacy, RO

New composite materials based on clay micro and nanoparticles, MWCNTs and polymeric films for the development of electrochemical sensors and biosensors have been realized. Particle size separation of two Romanian bentonites from Răzoare and Valea [...]

Electrical conductivity of carbon nanopowder fillers and their respective polymer composites prepared via latex technology

Ghislandi M., Marinho B., Tkalya E., Koning C.E., de With G., Eindhoven University of Technology, NL

The electrical conductivity of graphene, multi-wall carbon nanotubes (MWCNTs) and carbon black (CB) nanopowders, and graphite powder is characterized in the form of paper-like films (buckypapers) and by means of powder compression. Subsequently, carbon filler [...]

Decorated Single- and Multi-Walled Carbon Nanotubes Aiming H2S Sensing

Verissimo C., Ding M., Abbaspourrad A., Star A., Moshkalev S., University of Campinas - UNICAMP, BR

Carbon nanotubes are suitable materials for gas sensing. To promote or improve sensitivity, as well selectivity, experimental procedures have been developed to modify CNTs by the attachment of metal and metal oxide nanoparticles on nanotube [...]

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. [...]

Size Matters: The outer diameter of multiwalled carbon nanotubes (MWCNTs) affects gene expression in female fathead minnows (Pimephales promelas)

Carter B.J., Griffitt R.J., Brown-Peterson N., Hammers H.R., Barber D.S., EcoArray, Inc., US

We used oligonucleotide microarrays to examine the gene expression patterns in female fathead minnows (Pimephales promelas) exposed to two different sizes (<8 nm and 50-80 nm outer diameter) and three concentrations (0.1 mg/L, 0.3 mg/L, [...]

In-situ synthesis of Cu nanoparticles on MWCNTS using Microwave irradiation

Rangari V.K., Dey S., Jeelani S., Tuskegee University, US

Microwave irradiation technique is successfully used to synthesize the copper coated MWCNTS in a one-pot reaction with and without surfactant. Since the graphite carbon absorbs the (in 2min 1100oC) maximum microwave radiation had led to [...]

CMOS Compatability of Carbon Nanotubes on SOI Devices

Haque M.S., Oei S.P., Teo K.B.K., Udrea F., Gardner J.W., Milne W.I., Cambridge University Engineering Department, UK

This paper reports for the first time PECVD and CVD growth of MWNTs both aligned and non aligned on high temperature partially depleted CMOS SOI substrates. We also report for the first time the growth [...]
