Cellulose Nanocrystals as Barrier Performance Enhancer of Extrusion-Blown PLA Films for Food Applications

Matuana L.M., Karkhanis S.S., Stark N.M., Michigan State University, US

Bio-based plastics from sustainable resources such as biomass are the best alternative to petroleum-based polymers because they provide solutions for reducing the general dependency on oil availability and environmental concerns about the use of common [...]

Temperature Stability of PAG-Doped-Graphene, Towards Commercial Production of Graphene Integrated Circuits

Al-Mumen H., Li W., Michigan State University, US

In our previous work we found out a highly in air stable technique, defect-less, and relatively high electron mobility for n-doping graphene nanomesh using PAG (an element of SU-8 resist compound). This work demonstrated the [...]

Sample Preparation by On-Chip Dielectrophoretic Separation and Concentration of Viable, Non-Viable and Viable but Not Culturable (VBNC) Escherichia coli

Packard M., Shusteff M., Alocilja E., Michigan State University, US

Although bacterial culture remains the gold standard for detection of viable bacteria in environmental specimens, the typical time requirement of twenty-four hours can delay and even jeopardize appropriate determination. In addition, culture is incapable of [...]

Antibody Immobilization on Conductive Polymer Coated Nonwoven Fibers for Biosensors

McGraw S.K., Alocilja E.C., Senecal A.G., Senecal K.J., Prata G.N., Senecal A.G., Senecal K.J., Michigan State University, US

Research is being performed to develop rapid and novel electrochemical biosensors for the detection of food pathogens at the US Army NSRDEC. The focus of the research is fiber based platforms to perform both capture [...]

Interaction of Polyamido-amine (PAMAM) nanoparticles with the glassy carbon supported bilayer lipid membrane

Jadhav S.R., Mark Worden R., Michigan State University, US

Polyamido-amine (PAMAM) dendrimers are hyperbranched polymers with uniform particle size making them ideal monodisperse nanoparticles. PAMAM dendrimers are being pursued as non-viral vectors for gene delivery due to their low immunogenicity and their ability to [...]

Synthesis of a nano electro-magnetic polymer and its application in a DCT biosensor

Pal S., Hummel E.B., Alocilja E.C., Michigan State University, US

This experimental study was focused on the development of a nanomagnetic conductive polymer and its application in a direct-charge transfer biosensor (Figure1) for the detection of Bacillus species. A polyaniline-γFe2O3 nanocomposite transducer was first synthesized [...]

Morphology and Phase Transitions in Styrene-Butadiene-Styrene Triblock Copolymer Grafted with Polyhedral Oligomeric Silsesquioxanes

Drazkowski D.B., Lee A., Michigan State University, US

Two symmetric triblock copolymers of polystyrene-butadiene-polystyrene (SBS) with different styrene content were grafted with varying amounts of polyhedral oligomeric silsesquioxane (POSS) molecules with either isobutyl or phenyl moiety. The POSS octamers, R’R7Si8O12 were designed to [...]

Multifunctional Nanocomposites Made of Polypropylene Reinforced with Exfoliated Graphite Nanoplatelets (xGnP)

Kalaitzidou K., Fukushima H., Drzal L.T., Michigan State University, US

Polypropylene is one of the most widely used polymers. It is an attractive material because of its combination of mechanical properties, ease of processing and low cost. This research explores modification of polypropylene through addition [...]

The use of PDF analysis to investigate local structure and domains

Paglia G., Bozin E.S., Billinge S.J.L., Michigan State University, US

Knowledge of the atomic-scale structure is an important prerequisite to understand and control the properties of materials. The main techniques used to determine atomic structure are x-ray, neutron and electron diffraction from which the Bragg [...]

Nylon – Exfoliated Graphite Nanoplatelet (xGnP) Nanocomposites with Enhanced Mechanical, Electrical and Thermal Properties

Fukushima H., Drzal L.T., Michigan State University, US

Since the late 1990’s, research has been underway in our group at Michigan State University to investigate the production, fabrication and modification of a new nano-sized carbon material, exfoliated graphite nanoplatelets [xGnP]. The xGnP is [...]
