Nonlinear Response in Nanoshear Modulation Force Microscopy: Fourier Analysis

Haugstad G., University of Minnesota, US

Oscillatory methods in scanning probe microscopy have enabled nanoscale tribology and rheology investigations on polymeric systems. Among these methods, shear modulation force microscopy has been used to probe phenomena such as the stick-to-slide transition, time-delayed [...]

Color-Masked and Nano-Size Catalysts Embedded in Polymers for Reducing Dioxin Emission

Choi J., Yang K.S., Jeong Y.S., Chung J.S., Pohang University of Science and Technology, KR

People have begun to make polymer containing catalysts for dioxin decomposition. To make high functional polymer containing catalysts for dioxin decomposition, catalysts have very small size and are colorless for their various application. The objectives [...]

Polymer Nanocoatings by Initiated Chemical Vapor Deposition (iCVD)

Gleason K.K., Pryce Lewis H.G., Chan K., Lau K.K.S., Mao Y., Massachusetts Institute of Technology, US

Initiated chemical vapor deposition (iCVD) is a novel process capable of producing a range of polymeric and multifunctional nanocoatings. Coatings can be made extremely thin (down to 10nm) on objects with dimensions in the nanometer [...]

Highly Dispersible Microporous Carbon Particles from Furfuryl Alcohol

Liu J., Yaoa J-F, Wanga H-T, Chan K-Y, The University of Sydney, AU

Molecular sieve carbons (MSCs or carbon molecular sieves) are a class of microporous, amorphous high-carbon materials, and they share with zeolites the ability to distinguish molecules on the basis of size and shape. MSCs have [...]

The Role of Different Parameters in the Properties of Carbon Nanotube Polymer Nanocomposites

Velasco-Santos C., Castaño V.M., CFATA-UNAM /ITQ, MX

This work presents diverse results which depend on different parameters that play an important role in the distribution, interaction and synergetic effect in composites developed with the incorporation of multiwalled nanotubes in different polymeric matrix. [...]

Probing the Morphology and Tribo-Response of Nanostructured Fluid Films for Personal Care Applications

Haugstad G., Avery A., University of Minnesota, US

We present a methodology for interrogating silicone-based polymer-surfactant complex films a few nanometers in thickness. The films include 2D regions of liquid character interspersed in regions of solid character. Images are radically different in a [...]

Nanoelectronic CO2 Breath Sensors

Star A., Joshi V., Thomas D., Niemann J., Gabriel J.-C.P., Valcke C., Nanomix Inc, US

The measurement of carbon dioxide levels in respiration is a standard of care or guideline according to the American Heart Association, the American Association of Respiratory Care, and the American Society of Anesthesiologists, and is [...]

Assisted Alignement of Carbon Nanotubes

Haik Y., Chatterjee J., Chen C-J., Bimagnetic Engineering Lab, US

Extensive research has been focused on the processing of carbon nanotubes polymeric composites. The ability to impose a preferred alignment of carbon nanotubes in a composite will increase the effectiveness of utilizing nanotubes in composite [...]

Electrical Property of Fullerene Films Polymerized by Argon Plasma Treatment

Maruyama R., Sony Corporation, JP

Fullerene (C60) is a promising material for nano-carbon device research. Control of the electrical property of C60 is necessary for applications. C60 polymer has great promise because its unique structure allows its electrical and optical [...]

A Low Cost Polymer Based Piezo-Actuated Micropump for Drug Delivery System

Liu H., Tay A.A.O., Wan S.Y.M., Lim G.C., Institute of Materials Research & Engineering, SG

This paper presents the design, realization and simulation of a novel polymer based check-valve micropump actuated by piezoelectric disc. Comparing with silicon substrate, polymer materials have such advantages as flexibility, chemical and biological compatibility, 3D [...]
