Diameter controlled synthesis of carbon nanotubes by CVD using steric-stabilized iron nanoparticle catalysts

Mayya K.S., Lee S., Yeo I-S, Chung U-I, Moon J.T., Samsung Electronics Co.Ltd., KR

Carbon nanotubes (CNT) are the subject of intensive investigation due to their potential applications in nanoelectronics, biological sensors, high performance materials etc. CNTs can be synthesized using variety of techniques of which synthesis using chemical [...]

Millimeter long vertically aligned single-walled carbon nanotubes by an ultra long lifetime of catalysts

Iwasaki T., Zhong G., Yoshida T., Aikawa T., Morikane R., Kawarada H., Waseda University, JP

Controlling the growth direction of SWNTs on a substrate is one of the most important issues for fabrication of SWNT-based applications, such as field effect transistors (FETs) and interconnects for LSI. We have succeeded in [...]

Diagnostics of carbon nanotube composites by Raman spectroscopy

Puech P., Bassil A., Barrau S., Demont P., Bacsa R.R., Bacsa W.S., Flahaut E., Bacsa R.R., Bacsa W.S., University Paul Sabatier, FR

Carbon nanotube polymer composites are very promising for applications due to their exceptional mechanical and electronic properties to improve the elastic properties of polymers or to make polymers conductive. The large surface of carbon nanotubes [...]

The Impact of Patent Reform on Nanotechnology: File Early and File Often

Featherstone D.J., Messinger M., Specht M.D., Sterne, Kessler, Goldstein & Fox, US

2005 could have be remembered as the year with the most significant changes to United States patent law since the Patent Act of 1952. The proposals to update U.S. patent law would substantially change the [...]

Addressing 3rd-Party Patent Protection in the Product Development Process

Weseman S., IP Focus Law Group, Ltd., US

Third-party patent protection can be an obstacle to product development and introduction. Some development efforts completely ignore patent issues until a late-term crisis arises. Identified too late in the product development cycle, patent issue may [...]

Influence of photo-initiator concentration on residual mechanical stress in SU-8 thin films

Psoma S.D., Jenkins D.W.K., Derbyshire G.E., Stevens R., CCLRC RUTHERFORD APPLETON LABORATORY, UK

The negative photoresist SU-8 is widely used in the development and fabrication of MEMS devices. The structures of the resist are the product of photochemical and thermal cationic processes and result in vertical sidewalls and [...]

Exfoliated Graphite Nanoplatelets [2] Surface Treatment

Askeland P.A., Fukushima H., Do I-H, Kalaidzidou K., Drzal L.T., Michigan State University, US

Since the late 1990’s, research has been underway in our group at Michigan State University to investigate the fabrication of new nano-size carbon material, exfoliate graphite nanoplatelets [xGnP]. The xGnP is fabricated from natural graphite [...]

Titanium Dioxide Nanostructured Coatings: Application in Photocatalysis and Sensors

Byrne J.A., Hamilton J.W.J., McMurray T.A., Dunlop P.S.M., Donaldson V.J.A., Rankin J., Dale G., Al Rousan D., University of Ulster, UK

This paper presents results concerning the fabrication, characterisation, and application of nano-structured titanium dioxide films. Applications include photocatalytic purification of water, “self-decontaminating” surfaces, and electrochemical biosensing.

Fabrication and Transistor Demonstration on Si-based Nanomembranes

Yuan H-C, Roberts M.M., Savage D.E., Lagally M.G., Ma Z., Celler G.K., University of Wisconsin-Madison, US

We demonstrate the fabrication of free standing Si, SiGe, and Si/SiGe/Si membranes and the ability to transfer them onto various kinds of host substrates. In addition to the unstrained Si, SiGe membranes, strained Si is [...]

Nano-Sized Polymer Micelle Synthesized from Cationic Gemini Surfmer

Ohkubo T., Koike T., Tsubone K., Tsuchiya K., Sakai H., Abe M., Tokyo University of Science, JP

In this study, we examine the synthesis and characterization of polymer micelle using polymerizable cationic gemini surfactant (surfmer). In this work, polymerizable cationic gemini surfmer, (CH2)2 [BrN(CH3)2C11H22OCOC(CH3)CH2]2 (GSM) was newly synthesized and characterized. Also, a [...]
