Nanopore detection of nerve agent degradation products

Guan X., Gupta J., Zhao Q., de Zoysa R.S., Jayawardhana D.A., The University of Texas at Arlington, US

Improved analytical capability for detection of organophosphate chemical agents (i.e. nerve gases) remains a high priority need in our continuing defense against future terrorist attacks. A nanopore stochastic sensing method for the rapid detection of [...]

Iron based 1D Nanostructures by Electrospinning Process

Eid C., Brioude A., Salles V., Plenet J.-C., Asmar R., Monteil Y., Khoury A., Khoury R., Khoury A., Khoury R., Miele P., Université Claude Bernard-Lyon 1, FR

Due to their strong shape anisotropy, one-dimensional (1D) nanomaterials, including nanotubes, nanowires and nanofibers exhibit specific properties that are not observed in the case of their bulk or particle counterparts.1 Moreover, when such nanomaterials display [...]

Visible Room Temperature Photoluminescence in Wet-Chemically Etched Silicon Nanowires

Sivakov V.A., Voigt F., Brönstrup G., Bauer G., Christiansen S.H., Institute of Photonic Technology, DE

Strong room temperature visible (red-orange) photoluminescence (PL) has been observed in wet chemically etched heavily (10E19 cm-3) and lowly (10E15 cm-3) doped silicon nanowires (SiNWs). Our observations strongly suggest that visible light emission at room [...]

Electronic Properties and Transitions States involved in the Pyrrole Oligomerization

Cuán A., Cortés-Romero C.M., Ramírez-Silva M.T., Romero-Romo M.A., Palomar-Pardavé M.E., Metropolitan Autonomous University- Azcapotzalco, MX

The electrochemical pyrrole polymerization mechanism at initial stages is theoretically studied through sequential monomer units coupling to obtain 2 to 9 oligomer formation. The transitions states involved in the initial stages give the sequential growing [...]

Characterization of Carbon Nanotube-reinforced Polyethylene Nanocomposite Produced by Cryogenic Ball-milling Process

Terife G., Narh K.A., New Jersey Institute of Technology, US

The morphology of polymer nanocomposite, and the degree of dispersion of the MWCNTs were studied using SEM and light transmission microscopy. Both MWCNT ropes and aggregates were observed; also wetting of the nanotubes by the [...]

Fabrication of poly(alizarin red)-carbon nanofibers composite film and its application as nitric oxide microsensor

Zheng D.Y., Hu C.G., Hu S.S., Hu C.G., Hu S.S., Wuhan University, CN

In this work, a poly(alizarin red) (PAR)-carbon nanofiber (CNFs) composite film was fabricated via a well-controlled in situ electro-polymerization method. This composite film exhibited good sensing and catalytic ability to the electrochemical oxidation of nitric [...]

Experiments to Investigate Electromagnetic Shielding Performance of Polyaniline-Coated Thin Films

Kim B.R., Lee H.K., Korea Advanced Institute of Science and Technology (KAIST), KR

Many studies on electromagnetic wave shielding/ absorbing materials have been performed. In particular, studies of novel materials have been carried out as an alternative to conventional shielding materials such as metallic materials. Recently, the investigation [...]

Mechanical and Moisture Resistance Performance of Silver Nanoparticle Reinforced Fish Skin Gelatin Films

Harding H., Ludwick A., Samuel T., Young S., Aglan H., Tuskegee University, US

Films from the biodegradable polymer gelatin have been studied for biomedical applications not only because of the film forming properties of gelatin, but also because of the availability and economical advantages of gelatin. In this [...]

Preparation and characterization of Sulfonated High Impact Polystyrene (SHIPS) ion exchange nanofiber by electrospinning

Hwang T.S., Choi E.J., Kwak N.S., Chungnam National University, KR

The study of nanofibers has been a subject of intensive research because of their unique properties and widespread applications in many areas. Among the various methods used to prepare nanofibers, electrospinning has been very attractive [...]
