Particle Characterization of Nanoscale Materials using Dynamic and Static Light Scattering

Bumiller M., DeLuca T., Mattison K., Rawle A., Malvern Instruments, Inc., US

Purpose: Novel materials with single particle dimensions at the nano scale are submitted to our laboratory on a regular basis. These samples include single walled nanotubes (SWNT), buckyballs, quantum dots and various metal oxides. Determining [...]

Unique Roles of DNA Wrapped SWNTs: In-situ Fabrication of Self-Doped Polyaniline Nanocomposites

Ma Y.F., Ali S.R., He H.X., Rutgers University, US

Inspired by the remarkable electrical conductivity, the superior mechanical properties of carbon nanotubes(CNTs), and the rich optical, electrical and electrochemical properties of conducting polymers, nanocomposites of conducting polymers and CNTs have been pursued with a [...]

Quantum Dot Modified Multiwall Carbon Nanotubes

Olek M., Büsgen T., Mulvaney P., van Embden J., Hilgendorff M., Mulvaney P., Giersig M., CAESAR, DE

The key advantage of our research is a noninvasive functionalization of carbon nanotubes, which ensures good dispersion and stability of carbon nanotubes (CNT) in a vast range of organic and inorganic solvents. The method can [...]

Qubit Entanglement from a Bipartite Atomic System in a Carbon Nanotube

Bondarev I.V., Vlahovic B., North Carolina Central University, US

The development of materials that may host quantum coherent states is a critical research problem for the nearest future. Important would be to demonstrate quantum information transfer between two quantum bits arbitrarily separated in the [...]

Interfacial Properties of Carbon Nanotube Arrays

Zalamea L., Pipes R.B., Purdue University, US

The present study springs from the investigation of Salvetat et al.4 wherein the ratio of flexural deformation to applied load of the carbon nanotube array was used to determine a reduced Young’s modulus and effective [...]

ZnO Nanoparticles Beaded Multiwalled Carbon Nanotubes

Zhu Y., Elim H.I., Foo Y.L., Triparthy S., Quek W.T., Ji W., Thong J., Sow C.H., National University of Singapore, SG

In this work, we report a hybrid system of ZnO nanoparticles on MWNT scaffolds synthesized via a very simple and straightforward process. This involved the coating of pure Zn on as-grown aligned MWNT films, followed [...]

Strong and versatile carbon nanotubes (CNTs) are finding new applications in improving conventional polymer-based fibers. Nanotube-reinforced composites could ultimately provide the foundation for a new class of strong and lightweight fibers with properties such as [...]

In Situ Synthesis of Carbon Nanotubes by Polymer Materials

Huang C.W., Hsu L.C., Li Y.Y., CCU, TW

Catalytically grown carbon nanotubes were prepared by in situ thermal decomposition of the polymer materials. Polymer material (PEG, polyethylene glycol) was employed as carbon source and nickel-based materials were used as catalytic precursors. These materials [...]

Separating Single-Walled Carbon Nanotubes by Length

Rauwald U., Schmidt D.J., Hauge R.H., Smalley R.E., Ziegler K.J., University of Florida, US

Single-walled carbon nanotubes (SWNTs) have received great attention because of their unique electronic and mechanical properties combined with their chemical stability. Typically, SWNTs are microns in length; however, intermediate lengths between small spheroidal fullerenes and [...]
