Tunneling Negative Differential Resistance in Flexible Silicone Graphite Composites

Littlejohn S.D., Nogaret A., Crampin S., University of Bath, UK

Developing flexible electronic materials with the ability to amplify signals is a major challenge for bioelectronics. The next step in developing an active nervous system calls for a flexible electronic material that produces a signal [...]

Calculation of Nanoparticle Filler Content in Solid or Liquid Dispersions

Khalfin R.L., Cohen Y., Technion – Israel Institute of Technology, IL

Nano composites have unique properties which depend to a large extent on the quality of the nanoparticle dispersion. An outstanding issue is the quantitative measure of fillers that are actually dispersed to dimensions below a [...]

Plasmon assisted two-photon direct laser writing of micro-structures composed of chiral Ag nanoparticles

Vidal X., Kim W-J, Baev A., S. Jee H., Tokar V., Swihart M.T., The Institute for Lasers, Photonics and Biophotonics, ES

We present an approach to produce micropatterns of metallic nanoparticles (NPs) that preserve key optical properties of the individual NPs. The technique uses a photothermal reaction induced by two-photon direct laser writing. The studied NP [...]

Europium-doped gadolinium sulfide nanoparticles as a multimodal imaging agents for bio-application

Park J.K., Lee S.J., Korea Research Institute of Chemical Technology, KR

Most of the magnetic nanoparticles based on iron oxides have been widely used experimentally for numerous in vivo applications such as magnetic resonance imaging (MRI) contrast enhancement, tissue repair, hyperthermia, medical diagnostics, and therapeutics. These [...]

Effective Removal Module by Excimer Irradiation Assistance

Pa P.S., National Taipei University of Education, TW

A new design module using an excimer irradiation to assist in micro-electroremoval process as a precise recycle modus for the digital paper of the touch-panel offers a faster per-formance in removing the Indium-tin-oxide thin-films from [...]

Shape-Controlled Synthesis and Catalytic Behavior of Supported Platinum Nanoparticles

Liu C., Fransson M., Zhou B., Headwaters Technology Innovation LLC, US

Shape-Controlled Synthesis and Catalytic Behavior of Supported Platinum Nanoparticles Selective hydrogenation reaction is influenced by many factors, which include the presence of catalytic activators or poisons, the temperature, pressure, solvent agitation and other conditions specific [...]

Prevention of Coalescence Stage from Nuclei at Initial Growth of Thin Film by Substrate Rotation in Physical Vapour Deposition

Koh S.K., Lee J-H., Han Y.G., Cho J-S, Joo J.H., Kralkina E.A., P&I Corp., KR

A method of nanoparticle fabrication in physical vapor deposition was introduced. Metal were deposited on the powdery substrate which were stirred by rotors. Particle size and prodcuction rate of metal nano particles were controlled by [...]

Integrated Microfluidic Device with an Electroplated Palladium Decoupler for Electrochemical Detection of the 8-hydroxydeoxyguanosine (8-OH-dG) DNA Adduct

Dawoud A.A., Kawaguchi T., Jankowiak R., Iowa State University, US

More sensitive and reliable microfluidic devices are needed for the detection of the 8-hydroxy-deoxyguanosine (8-OH-dG) DNA adduct, one of the most frequently used biomarkers reporting on oxidative stress. Therefore, we have developed a capillary electrophoresis [...]

Environmentally Friendly Pathways for Synthesis of Titanium Dioxide Nano-particles

Li H., Sunol A.K., Sunol S.G., Sunol A.K., Sunol S.G., University of South Florida, US

Titanium Dioxide is an important catalyst for oxidation of hazardous compounds in air and water particularly for photo-catalysis. Although it is traditionally used for photo-catalysis with UV light, when its energy band gap is reduced, [...]

Vibrating Nanotube–based Nano Powder Production System

Akhatov I.S., Jang B.Z., Rastgaar Aagaah M., Schmidt D.R., Mitlyng A.S., Stewart M.B., Mahinfalah M., North Dakota State University, US

In this paper we present a new nano powder production method. Basic idea of this method is as follows: a nanotube being placed in a vapor atmosphere will provoke condensation of vapor on the tip [...]
