Biodiesel Co-product Utilization: Glycerol-derived Films for use in Commercial Applications

Wyatt V., Strahan G., Liu C-K., Jin T., United States Department of Agriculture, US

Developing new outlets for glycerol would have a significant impact on the economics of biodiesel production if value-added products made from glycerol can be identified. Glycerol is the major co-product produced from the process used [...]

Layer-on-layer Assembly of Macroscopic 2D and 3D Carbon Nanomaterial Architectures

Patel S.C., Lalwani G., Alam O., Grover K., Qin Y-X, Sitharaman B., Stony Brook University, US

Although carbon nanomaterials are often labeled as the future replacement for silicon in electronics and a new generation of robust materials, there are major shortcomings in the assembly of carbon nanomaterials into higher order structures. [...]

Computer Simulation of Phase Transitions and Orientational Order in Low-and High-molecular Ferroelectric Nano-Systems

Maksimov A.V., Maksimova O.G., Maksimova O.G., Petrova T.O., Nastuljavichus A.A., Baruzdina O.S., Cherepovets State University, RU

A computer simulation of processes of polarization of the low-and high-molecular ferroelectric systems has been made by the Monte Carlo method. The developed program complex has been tested by the comparison with analytical calculations and [...]

Effect of Carbon Black and Silver Nanoparticle Loading on the Structural and Thermo-Mechanical Properties of Chitosan-Based Films

Blagg A., Perales-Perez O., Valentin R., University of Puerto Rico-Mayagüez, PR

This work addresses the synthesis and structural and thermo-mechanical characterization of bare and chitosan-based nanocomposite films synthesized via spin coating and sol casting techniques. The dependence of these properties as a function of the nature [...]

Fabrication of biodegradable zein films by using soft lithography

Altunakar B., Kokini J.L., University of Illinois at Urbana-Champaign, US

Microfluidic components are widely used in the design of both bioanalytical and diagnostic microdevices. The miniaturized sample volumes together with modifications of the surface chemistry and localization of molecules within microfluid channels has opened many [...]

Effect of Size on Properties of Nano-Structured Polymers –Transition from Macroscaling to Nanoscaling

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR

The growth in investment on the effect of size in nanoscience and nanotechnology has been astounding. Among the $12.4B spent in 2006 worldwide Nanotechnology research funding (Lux Research, 2007), at least 50%, that is >$6B, [...]

Nanoscale hydrophobic coatings for the separation of liquid mixtures

Truman P., Frenzel R., Longari N., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Organofunctional nanoscale silane coatings are widely used to modify surface chemistry. Such coatings have many applications in micro- and nanofluidics because liquid motion on these scales is strongly influenced by capillary or wall effects. In [...]

Nanocharacterization Using Secondary Ion Mass Spectrometry (SIMS)

Novak S.W., Magee C.W., Evans East - Evans Analytical Group, US

Secondary Ion Mass Spectrometry (SIMS) has been widely applied for depth profile analysis in the semiconductor industry, but less widely applied to characterization of other materials. Evans East has developed techniques over the last few [...]

Coating of Glass Surfaces with Nanoparticles of different Materials Synthesized in Microemulsions

López-Trosell A., Schomäcker R., TU Berlin, DE

In this paper a developed methodology is presented to coat glass substrates with nanoparticles of different materials. Particles of palladium, zirconium oxide, yttrium iron garned and perovskite Ca0.5Sr0.5MnO3 were synthesized in microemulsions. The microemulsions form [...]
