Conjugated Polymer Papers for Metal Ion Detection

Ahn K-J, Yoon H., Chonnam National University, KR

It is of great importance to detect heavy metal ion in solution. Here, we describe the electrochemical detection of metal ions using polypyrrole/cellulose (PPCL) composite papers in both static and flow systems. A home-made electrochemical [...]

Surface Hydrophobization of Micro- and Nanofibrillated Cellulose and Blending Property in PLA Nanocomposites

Samyn P., University of Freiburg - Freiburg Institute for Advanced Studies, DE

Cellulose fibers are advantageous reinforcing materials for bio-based composites because of their availability and good mechanical properties. Several chemical processes have been developed to turn the native fibers into micro- (MFC) or nanofibrillated (NFC) cellulose [...]

Structure and the interactions in the crystal structure of cellulose III-I calculated by using ab initio molecular dynamics simulation

Ueda K., Ishikawa T., Miyamoto H., Hayakawa D., Yokohama National University, JP

The structure and the interactions existing in the crystal of cellulose IIII was evaluated by using the computational chemical approach. Cellulose is one of the most abundant renewable resources and the application of it to [...]

NanoBandage for Controlled Release of Topical Therapeutics

Patchan M., Calderon-Colon X., Benkoski J., Theodore M., Le H., Fuller B., Boggs N., Nelson A., Garza L., Sarkar K., Brandacher G., Patrone J., The Johns Hopkins University Applied Physics Laboratory, US

Burn injuries, trauma, and surgical procedures result in complex wounds, which can lead to pain, infection, and scarring. Management of complex wounds remains a critical challenge for the medical community and effective, localized treatments are [...]

Measuring Degradation Processes of Model Coatings Related to Bioenergy Applications

Dixon M.C., Oom A., Q-Sense a Division of Biolin Scientific, US

Degradation mechanisms are relevant to a wide variety of applications including the bioenergy, biomaterial, semiconductor, and detergent industries. Therefore, it is of interest to study these mechanisms, for example, to better tailor formulations for enzymatic [...]

High-Yield Chemical Conversion of Biomass into Biofuels and Value-Added Products

Mascal M., Nikitin E.B., University of California Davis, US

We have developed a new method to efficiently convert waste biomass (agricultural, municipal forestry) into biofuels and value-added products. The process is completely chemical in nature, inexpensive, and produces no waste stream. The derived products [...]

Nano cellulose crystallites: optical, photonic and electro-magnetic properties

Simon D., Kadiri Y., Picard G., Ahuntsic College, CA

(NCC) are tubes, about 200 nm long and 20 nm in diameter. This is a natural product, found in wood. It is separated by paper mills from long fibers, and rejected in mass volumes. In [...]

Novel Hybrid Materials of Cellulose Fibres and Nanoparticles

Small A.C., Johnston J.H., Victoria Univeristy of Wellington, NZ

The combination of organic and inorganic materials provides the opportunity to develop new materials that not only retain the inherent properties of their component precursors but may also exhibit new properties due to the synergistic [...]

Nitrocellulose-Stabilized Silver Nanoparticles as Low Conversion Temperature Precursors for Inkjet-Printed Electronic Circuits

Nguyen B.T., Nguyen M.T., Gautrot J.E., Nguyen B.T., Nguyen M.T., Zhu X.X., Université de Montréal, CA

Liquid-based inkjet printing is considered as a constructive (rather than destructuve) low-cost technique for printed circuit boards fabrication. A convenient way of depositing silver films and lines using inkjet technology is to generate silver nanoparticles [...]
