Increasing Engine Efficiency with Friction Reducing-Oil Additives

Christensen G., Grablander T., Bailey C., Lou D., Hong H., Novum Nano, US

Typical engine oils used in internal combustion gas and diesel engines are not high in thermal conductivity and are limited in friction performance, which together limit engine efficiency and longevity. Carbon nanotubes and hexagonal boron [...]

Conductive Coatings Eliminate Static Discharge Risk on Aircraft

Christensen G., Lou D., Grablander T., Younes H., Bailey C., Hong H., Novum Nano, US

Electrically insulating aircraft materials and coatings increase the likelihood of dangerous charge buildup due to static electricity accumulation and cannot protect from lightning strikes. An electrically conductive coating that will prevent static charge buildup and [...]

Development of “paper transistors” with new structure using carbon-nanotube-composite papers for aiming to construct logic circuits

Iijima R., Oya T., Yokohama National University, JP

We propose new “paper transistors” with unique structure using carbon-nanotube (CNT)-composite papers for aiming to construct “paper logic circuits.” Recently, the CNT that is one of nano-carbon materials has been receiving increasing attention because it [...]

Advancing Sustainable Manufacturing of Carbon Nanomaterials and Devices through Life Cycle Assessment

Shih W-S, Chappell M.A., Kennedy A.J., Brewer Science, Inc, US

Responsible development of nanotechnology and fostering nanotechnology into products for commercial and public benefit are two of the four long-standing National Nanotechnology Initiative (NNI) goals [1]. To achieve these goals, nanotechnology-related environmental, health, and safety [...]

Recoverable Lightweight Nanocomposites

Huckleby A.B., Li J., Shahrizan Jamal M., Zhang M., Florida State University, US

The demand for lightweight and strong structures continues to rise especially for weight critical applications such as aerospace and automotive. It is also desired that the materials can recover after being deformed. In this work, [...]

Strain sensing with CNT nanocomposites: static, cyclic and dynamic electromechanical material characterization.

Magnafico E., Casalotti A., Karimzadeh M., Chytanya Chinnan K., Lanzara G., University of Rome, Roma Tre, IT

Carbon Nanotube (CNT) nanocomposites are one of the most important candidates to realize innovative strain sensors for Structural Health Monitoring (SHM) applications. In this work, sensors were made of Multi-walled Carbon Nanotubes (MWNTs) embedded in [...]

Dispersion technology for CNTs with nano pre-mixer

Takatsuka T., Iida Y., THINKY corporation, JP

Carbon nanotubes (CNTs) and other strongly aggregated materials by van der Waals’ force are known for their excellent material properties with fewer amounts when they are deagglomerated and dispersed. Nano pre-mixer’s, PR-1* (THINKY, Japan), operating [...]

An All-in-One Nanomechanical Bio-nanofluidic System for Possible Applications as Sensor and Actuator in Precise Drug Delivery

Fakhrabadi M.M.S., Università Degli Studi di Padova, IT

The paper presents the physical design and mathematical formulation of a bio-nanofluidic device for possible applications in nanoengineering in general and bio-nanoengineering in particular such as in precise drug delivery as sensors and actuators. The [...]

Sensing Solution for Airborne Carbon Nanotube Exposure in Workplaces Based on Surface-Enhanced Raman Spectroscopy

Bieri R., Borek-Donten J., Celikkol Zijlstra B., Cattaneo S., Bürgi T., Stat Peel, CH

Today’s advances in man-made nanomaterials pose new and unprecedented health risks, arising especially from airborne, inhalable fiber-shaped nanomaterials, like carbon nanotubes (CNTs). In vivo studies indicate that inhalation of CNTs can cause adverse pulmonary effects [...]

Kinetics study of carbon nanotube alignment under shear force via real-time polarized Raman spectroscopy

He Y., Taub A.I., University of Michigan-Ann Arbor, US

Carbon nanotubes (CNTs) have been studied extensively since their discovery by Iijima in 1991. They have a unique quasi one-dimensional nanoscale structure with remarkable mechanical, electrical and thermal properties. Numerous investigations have been done on [...]
