The Fabrication and Characterization of Nanocarbon Foam as Novel Wick Material for Thermal Management of Electronics

Li J., Xie J., Zhang M., Florida State University, US

Semiconductor devices have suffered large on-chip temperature gradients due to localized high heat flues resulting from the substantial non-uniformity in power dissipation. To solve the heat problems, the flat heat pipes (HPs) are excellent candidates [...]

Progress towards total structure control in SWCNT populations

Fagan J., National Institute of Standards and Technology, US

As-synthesized single-wall carbon nanotube (SWCNT) populations contain substantial distributions of SWCNT structures, including in the distribution of species ((n,m) chiralities) and enantiomers (i.e. the handedness of the lattice vector), as well as in their lengths, [...]

Release of Carbon Nanotubes from Nano-polymer Composites during Environmental Aging

Sahle-Demessie E., Han C., Zhao A., Wang J., Grecsek H., U.S. Environmental Protection Agency, US

Over the past two decades there has been a significant increase in commercial products incorporating engineered nanomaterials (ENM) that are now are used in electronic, cosmetics, automotive and medical products and in environmental applications. Although [...]

Characterization of electrical property and band-structure in carbon nanotube/GaN hetero-interface

Yokogawa T., Miyake S., Yamashita A., Yamaguchi University, JP

Recently power devices using GaN have attracted much attention because of high power and high efficiency due to the wide band-gap. These power devices are generally used in high temperature operation by the heat dissipation [...]

Impact of Gate Oxide Thickness and Channel Thickness on DC Performance of Carbon Nanotube Tunnel FET

Bhosale K.S., Jawake A.V., Aher S.R., Borse H.S., Patil G.C., Patil S.R., Patil G.C., Patil S.R., JSPM’s Rajarshi Shahu College of Engineering, IN

The scaling down of conventional complementary metal–oxide–semiconductor technology is suffering from fundamental limitations. To overcome these problems, novel engineering solutions like improving the device architecture,introducing materials into the channel region with superior transport properties, and [...]

Manufacturing of a Continuous CNT Rollstock

Chan E.M., General Nano, US

In Q1 2014, General Nano was awarded a Commercial Readiness Program by the Air Force to scale uniquely long and pure MWCNTs. To accelerate time to commercialization and to minimize capital expenditure, a strategy chosen [...]

Carbon Nanotube Immobilized Membranes for Next Generation Desalination

Roy S., Bhadra M., Mitra S., New Jersey Institute of Technology, US

The objective of this project is to utilize carbon nanotubes (CNTs) to create breakthrough membrane properties for the generation of pure water via membrane distillation (MD). This fundamentally new approach will reduce the cost and [...]

Aerosolization of Carbon Nanotubes Using an Acoustic Generator: Particle Generation and Properties

Ku B.K., Eileen Birch M., CDC/NIOSH, US

With increasing applications and global production of carbon nanomaterials, there is a growing concern about workplace exposure. The National Institute for Occupational Safety and Health (NIOSH) has recommended a working lifetime exposure limit (REL of [...]

Investigating Environmental Weathering of CNF/CNT/ Thermoplastic Polymer Synthesized using Additive Manufacturing

Sahle-Demessie E., Zhao Amy, Stephen Chady, U.S. Environmental Protection Agency, US

Additive manufacturing (aka, 3D printing) is an emerging technology for making a new class of multifunctional nanocomposites for many niche items such as medical implants, and a wide range of industrial designed components. Additive manufacturing [...]

Influence of CNT concentrations to polyurethane / multi-walled carbon nanotube composites on the thermoelectric performance

Wu Q., Hu J., The Hong Kong Polytechnic University, HK

In this paper, we investigated the possibility of applying polyurethane in thermoelectric application, and the influence of MWNT concentrations to polyurethane / multi-walled carbon nanotube composites on the thermoelectric performance. Polyurethane was used as the [...]
