Passive Microrheology : Non Intrusive Measurement of the Emulsions Stability

Tisserand C., Fleury M., Brunel L., Bru P., Brunel L., Meunier G., Formulaction, FR

This work presents a new technique of the passive microrheology for the study of the microstructure properties of soft materials like emulsions. Our technology uses Multi Speckle DWS (MS-DWS) set-up in backscattering with a video [...]

Passive Temperature-Compensation of MEM Resonators

Rottenberg X., Jansen R., Stoffels S., De Coster J., De Raedt W., De Coster J., De Raedt W., Tilmans H.A.C., IMEC, BE

MEM-resonators are recognized key components for future sensing, wireless and communications applications. Si-based resonators have gained special interest since they offer the perspective to replace bulky quartz resonators on-chip, maintaining high Q-factor and reaching high [...]

Magnetoliposomes: Stability of Magnetic Nanoparticles in Suspension for drug delivery

Sen T., Sheppard S.J., Mercer T., Elhissi A., University of Central Lancashire, UK

A simple and rapid one pot method of synthesis of magneto-liposome has been reported. The nanoparticles exhibited exceptional stability in suspension. Magnetoliposomes were efficient for DNA binding/elution and drug loading.

Mechanical and Thermal Stability of Carbon Nanotube Junctions

Shi S.Q., Liu W.C., Meng F.Y., The Hong Kong Polytechnic University, CN

Mechanical and thermal stability of carbon nanotube junctions was studied using molecular dynamics simulation method. Junctions made from armchair and zigzag thin carbon nanotubes were first formed by thermal welding process, then tested under 1D [...]

Bifurcation Behavior of a Novel Auto-thermal Circulating Fluidized Bed (CFB) Membrane Reformer

Abu-Mahfouz I., Elnashaie S., Ciocci R., Penn State University at Harrisburg, US

Static Bifurcation (SB), which mostly exhibits itself as multiple steady states, is characteristic of a novel auto-thermal Circulating Fluidized Bed Membrane Steam Reformer (CFB_MSR) for hydrocarbons. The present paper focuses on the practical implications of [...]

Quantitative Analysis of HBV Capsid Protein Geometry Based Upon Computational Nanotechnology

Soundararajan H.C., Sivanandam M., Sri Venkateswara College of Engineering, IN

Computational biology is an interdisciplinary field that applies the techniques of computer science, functional mathematics and statistics to address problems inspired by biology. Numerous studies have shown that structure of proteins contribute towards their functionality [...]

Assessment of L-DUMGAC MOSFET for High Performance RF Applications with Intrinsic Delay and Stability as Design Tools

Chaujar R., Kaur R., Saxena M., Gupta M., Gupta R.S., Gupta M., Gupta R.S., Semiconductor Devices Research Laboratory, IN

The paper assesses RF performance of L-DUMGAC MOSFET using ATLAS device simulator by performing AC simulations at very high frequencies, hence, proving its efficacy for high performance RF applications. Higher Gma & K; and lower [...]

Organic versus Hybrid Coacervate Complexes: Co-Assembly and Adsorption Properties

Fresnais J., Berret J.-F., Qi L., Chapel J.-P., Castaing J.-C., Laboratoire Matière et Systèmes Complexes, FR

We report the co-assembly and adsorption properties of coacervate complexes made from polyelectrolyte-neutral block copolymers and oppositely charged nanocolloids.

Conducting Polymer Nanocomposites: Role of DNA Functionalized Carbon

Cheung W., Bogozi A., Ma Y., Mao G., Mao G., He H., Rutgers University, US

In this work, a water-soluble self-doped polyaniline nanocomposite was fabricated by in-situ polymerization of 3-aminophenylboronic acid monomers in the presence of single-stranded DNA dispersed- and functionalized- single-walled carbon nanotubes. For the first time, we found [...]

Influence of Stress and Temperature on the Microstructure Stability of Nanocrystalline Materials

Rajgarhia R.K., Koh S-W., Spearot D., Saxena A., Selvam P., Tummala R., University of Arkansas, Fayetteville, US

Nanocrystalline materials have improved mechanical and electrical properties in comparison to their microcrystalline counterparts due to their reduced crystallite or grain size. Loss of these unique properties due to grain growth under the affect of [...]
