An explosive impact technique to nanocrystallize and harden surface of metal materials

Tong S.J., Tong Z., Shi Z.M., Tong S.J., Tong Z., Inner Mongoli University of Technology, CN

An explosive impact surface nanorisation technique (EISNT) was developed to prepare nanostructured surface layers on medium carbon steel (MCS) and pure Copper (PC) plates. The plastic deformation involved the entire plate depth of 4-6 mm, [...]

The Rheology and Processing of Carbon Nanotubes for Polymer Composite Applications

Ma A.W.K., University of Connecticut, US

Carbon nanotubes (CNTs) have a diameter on the nanometer scale and a length on the micrometer or even centimeter scale. The high-aspect-ratio (length to diameter ratio) of CNTs offers a unique competitive advantage for using [...]

Composite microelectrodes from PEDOT and carbon nanotubes enable advanced neuronal recording, stimulation and sensing

Gerwig R., Cesare P., Kraushaar U., Reinartz S., Giugliano M., Kilias A., Ruther P., Stett A., Stelzle M., Natural and Medical Sciences Institute, NMI, DE

The aim of this work was to design an advanced microelectrode material for neurotechnology. In order to improve signal-to-noise ratio, stimulation and sensing properties as well as cell viability, microelectrodes were modified with poly(3,4-ethylenedioxythiophene) (PEDOT) [...]

MWCNTs and SWCNTs based Nanocomposites for Cartilage and Bone Tissue Regeneration

Zhang L.G., Holmes B., The George Washington University, US

Cartilage and bone defects, which are caused by a variety of reasons such as traumatic injuries, osteoarthritis, osteoporosis or bone cancers, represent common and severe clinical problems. Developments in nanotechnology and tissue engineering have provided [...]

Chemical Synthesis of Graphene Nanoribbons

Hernández-Arriaga D., González-González F.J., Segura-Cárdenas E., Reyes-Reyes M., López-Sandoval R., Universidad Autonoma de San Luis Potosi, MX

Carbon Nanotubes (CNTs) have been the reason of studies since they were discovered in 1991 and now the new innovator material is Graphene. Geim and Novoselov achieved a single sheet of Graphene. The importance of [...]

Antibacterial effect of Silver Carbon Nanotubes against Multi-drug resistant Pseudomonas aeruginosa

Dosunmu E., Pillai S., Vig K., Singh S.R., Dennis V.A., Coats M., Alabama State University, US

Silver carbon nanotubes AgCNT inhibited the growth of P. aeruginosa at the lowest concentration of 60 µg/ml for at least 12 hr. Further studies of structural and morphological changes would further elucidate the mechanism of [...]

Fabricating CNT/ PEDOT:PSS Composite on Flexible Substrate Using Transfer Printing

Wu W-T, Tsai H.T., Hsu C-M, Southern Taiwan University of Science and technology, TW

In this paper, we propose a novel approach to fabricate CNT/ PEDOT:PSS composite with transfer printing, in which the highly oriented CNT could be obtained. The preparation of CNT/ PEDOT:PSS composite started with the synthesis [...]

Field Emission Emitters Fabricated Using Carbon Nanotube Blasting

Hsu C-M, Wu J-S, Wu K.-C., Wu W-T, Liu T-S, Wu J-S, Wu K.-C., Wu W-T, Wu J-S, Wu K.-C., Wu W-T, Chen J-A, Southern Taiwan University of Science and technology, TW

This work proposed a novel approach, named CNT-blasting, aiming to fabricate cost effective CNT-field-emission anodes with high emission performances. This approach implants CNTs directly onto a screen printed silver paste by traditional sand blasting method, [...]

New Electromagnetic Shielding Sheets Using Carbon-Nanotube-Composite Papers

Li B.J., Ito W., Hiwatashi H., Oya T., Yokohama National University, JP

We propose new electromagnetic shielding(EMS) sheets using carbon-nanotube(CNT)-composite papers. The paper has good electrical conductivity in spite of a paper, the weight is light, and there is no deterioration problem because of both the CNT [...]

Fabrication and Characterization of Carbon Nanotube/Graphene Hybrid Foam

Zhang M., Cui Y., Li S., Florida State University, US

CNT foam is a material with a porous structure constructed with nano-porous carbon, carbon nanotubes (CNTs). It is expected that CNT foam derives many of its functions from both its nanostructure and its microstructure and, [...]
