The Reaction of Nano-scale Iron Fluidized in Microwave Radiation Field to Treat Chlorobenzene

Lee C-L, Wang H.P., Wang Y-S, Wu C-R, Wang H.P., Wang Y-S, Jou C.-J.G., National Kaohsiung First University of Science and Technology, TW

Microwave (MW) energy is combined with nano-scale iron particles fluidized in aqueous chlorobenzene (CB) solution for reducing the activation energy of CB to enhance it decomposition. When the metal particles are fluidized in solution, the [...]

Polarity sensitive colloidal gold nanoparticles

Amin F., Yushchenko D., Zhang F., Zulqurnain A., Parak W.J., Philipps Universität Marburg, DE

Polarity sensitive gold nanoparticles have been synthesized and their fluorescence properties have been measured. The effect of external factors such as alcohols, polyamines and detergents has been investigated.

Green Chemistry Used in the Synthesis and Characterization of Silver and Gold Nanoparticles

Vallejo R., Segovia P., Elizondo N., Vázquez O., Coello V., Castaño V., Universidad Autonoma de Nuevo Leon, MX

Gold (Au) and silver (Ag) nanoparticles have a diversity of interesting properties between which they emphasize the electrical ones, optical, catalytic and the applications in biomedicine like antibacterial and antiviral, same that depend on their [...]

Early Stages of Particle Formation by in-situ UV-Vis and HRS

Schürer B., Segets D., Peukert W., University of Erlangen-Nuremberg, DE

We present a new approach for the study of early states of particle formation that can be applied also for precipitation processes that occur on a millisecond timescale. A T-shaped micro-mixer is used to precipitate [...]

Characterization & Synthesis Nano magnetic particles. Ms. Meera Thiyagarajan AP/Physics, Department of Physics Vivekanandha Institute of Engineering and Technology for Women. Magnetic particles find wide applications and specifically as memory device. The emerging new storage [...]

Fuel cell catalysts based on core-shell nanoparticles

Xu H., Zalitis C., Rivera-Hernandez M., Albrecht T., Kucernak A., Imperial College London, UK

In this contribution, we focus on the different approaches to dispersing Pt and Co/Pt core/shell nanoparticles in solution and then depositing them on representative catalyst supports. These include gold or highly ordered pyrolytic graphite (HOPG) [...]

Size dependent photoluminescence characteristics of GaN nanoparticles

Chen Y., Kang K.S., Jyoti N., Kim J., Inha University, KR

Various size of GaN nanoparticles have been fabricated with sol-gel method using Ga(NO3)3 as a presusor, HNO3 as a solvent, NH3OH as a pH adjusting agent, and citric acid as a chelating agent. After adding [...]

Synergistic effect of Cobalt and Nitrogen doping on Anatase Titania for Photodegradation under Visible light

Binitha N.N., Yaakob Z., Silija P.P., Resmi M.R., Suraja P.V., National University of Malaysia, MY

This work reports on the synergistic effect of cobalt on Carbon and Nitrogen codoped anatase titania photocatalysts prepared via sol–gel method using urea as the nitrogen source. Visible light activity is achieved as result of [...]

Hydrothermal Growth of ZnO Nanostructures Using Zinc Thin Films as Seed Layer

Yang J-Y, Cheng H-W, Cheng T.-C., Cheng H-W, Cheng T.-C., Li Y., National Chiao Tung University, TW

Different zinc oxide nanostructures are selectively synthesized by a simple reaction of zinc acetate dihydrate with hexamethyltetramine (HMT) under mild hydrothermal conditions using zinc thin films as seed layer. Scanning electron microscopy (SEM) result of [...]

Microwave-assisted synthesis of water soluble ZnSe@ZnS quantum dots

Bailon-Ruiz S.J., Perales-Perez O., Singh S.P., University Of Puerto Rico at Mayaguez, PR

Semiconductors nanocrystals known as quantum dots (QD’s) have attracted much attention because of their optical properties can be tuned just by controlling their crystal-size, composition and shape at the nanoscale. Compared to organic dyes, quantum [...]
