Linseed oil miniemulsions stabilized by polyelectrolyte complex (gum arabic-chitosan)

Michel-Barba M.G., Espinosa-Andrews H., Centro de Investigación y Asistencia en Tecnología y Diseño del Estado de Jalisco, a.C., MX

An linseed oil miniemulsion was optimized using the microfludization process and finally stabilized by polyelectrolyte complexes formation. Emulsion preparation variables such as gum arabic/oil mass ratio (GA/O), oil volume fraction (), homogenization pressure and number [...]

Magnetic Nanofluids in Ultrasonic Testing

Sokolov V.V., Osipov M.I., Moscow State University of Instrument Engineering and Computer Science, RU

The use of the magnetic nanofluid as the bonding medium find an ever increasing application in ultrasonic non-destructive testing method. A thin layer of magnetic nanofluid which is adhered on the transducers face with a [...]

Relationship between Morphology and Electrochemical Properties of Polyaniline in the Nanometer Regime

Lee Y., Yoon H., Chonnam National University, KR

Polyaniline (PANI) has found a wide range of applications due to its electrical properties, reversible redox behaviors and environmental stability. Here, we report the preparation of PANI nanostructures with three different aspect ratios, namely, nanospheres, [...]

Durable Superhydrophobic Coatings for Icephobic Applications

Nahum T., Mitra S., Panwar A., Barry C., Dodiuk H., Kenig S., Mead J., UMass Lowell, US

Recent studies about the application of superhydrophobic surfaces for anti-ice properties have found that ice adhesion strength is reduced significantly compared to bare aluminum surfaces, but these surfaces lack durability. In this work, bottom up [...]

Polymer Nanostructure Approach for Photoelectric Solar Energy Conversions

Sun S., Norfolk State University, US

At materials molecular level, photoelectric/photovoltaic conversion corresponds to a photo induced electron transfer from a molecular electron rich donor entity to an electron deficient acceptor entity, and the process is also called photo induced exciton [...]

Kinetically Controlled Formation of Deposited Polymer Nanomaterials with Unique Surface Substructures

Choi H., Yoon H., Chonnam National University, KR

One-dimensional (1D) electronic materials with inherent nanoscale features are considered to be promising components for achieving unprecedented future technologies. Much effort has been devoted to the synthesis of inorganic nanomaterials and, as a result, unique [...]

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 [...]

Conducting Polymer Based Adhesives for Electrochemical Applications

Choi H., Yoon H., Chonnam National University, KR

There has been huge demand for developing advanced materials and devices for enhanced energy storage. However, relatively little attention has been devoted so far to the development of efficient binders for electrode materials. In this [...]

Polymerized Ionic Liquid Films in Strong Electric Fields: Ion Transport and Nanopatterning

Kumar R., Bocharova V., Strelcov E., Tselev A., Collins L., Kravchenko I.I., Berdzinski S., Strehmel V., Ovchinnikova O.S., Minutolo J.A., Sangoro J.R., Agapov A.L., Kisliuk A., Soko A.P., Oak Ridge National Laboratory, US

The current work represents an important step in a search for novel materials and experimental techniques that would allow for controllable and inexpensive methods of surface patterning with nanoscale resolution. The novelty of the nanopatterning [...]

Layered Quantum Dot based Chromogenic Membranes for pH Sensing

Cole I.S., Trinchi A., Hardin S.G., CSIRO, AU

The development of inexpensive, flexible, robust pH sensors with an optical mode of operation remains a key challenge. Monitoring pH is a critical capability, and in most lab applications is carried out using the electrochemical [...]
