Influence of an alternating current on silver nanoparticles’ formation processes in a polymeric matrix

Amerkhanova Sh.K., Belgibaeva D.S., Shlyapov R.M., Tatibaeva M.S., Erzhanova Sh.A., Karaganda State University, KZ

Influence of an alternating current with various frequencies from 500 to 5000 Hz on silver nanoparticles formation process in the presence of polyvinyl alcohol is investigated. It is shown that influence by an alternating current [...]

Composition and magnetic properties of zinc ferrite nanoparticles prepared by co-precipitation method at different temperatures

Reisi Shahraki R., Seyyed Ebrahimi S.A., Ebrahimi M., University of Tehran, IR

In this work, single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 40, 60 and 80 °C without any subsequent calcination and the effect of the reaction temperature on the composition, structural [...]

Structural refinement and photoluminescence properties of cube-like (Ca1-xCux)TiO3 crystals synthesized by the microwave-hydrothermal method

Oliveira L.H., de Moura A.P., Cavalcante L.S., Gutierrez S.A., Longo E., Varela J.A., Universidade Federal de São Carlos, BR

In this work, (Ca1-xCux)TiO3 crystals with (x = 0, 0.01 and 0.02), were synthesized by the microwave-hydrothermal method at 140ºC for 32 min. The photo-physical properties were studied to analyze the influence of Cu2+ doping [...]

Carbon coated FeRu and CoRu nanomagnets and their potential for medical application

El-Gendy A.A., Hampel S., Leonhardt A., Khavrus V.O., Büchner B., Klingeler R., National Institute for standards, EG

This work presents a novel synthesis procedure for carbon-coated magnetic nanoparticles and their detailed characterization regarding structure, morphology, and magnetic properties. To be specific, the high pressure chemical vapour deposition technique (HPCVD) has been applied [...]

MD Simulations on the Momentum Transfer to Nano Contaminant Particle on Wafer Surface in Collisions with Cleaning Bullets

Choi M.S, Lee J.W., POSTECH, KR

This study aims to clarify the basic mechanism through MD simulations on momentum transfer during collisions between target contaminant and cleaning bullet particles both in the nanometer size range. Even in conditions where the contaminant [...]

Simultaneous removal of nano-sized contaminant particles with multi-modal size distribution using hybrid particle beams

Kim I., Lee J.W., POSTECH, KR

The removal of contaminant particles(CPs) as small as 10nm from wafer surface is essential in successful fabrication of nano-scale devices. The supersonic particle beam technique using nano-sized volatile bullet particles(BPs) was extremely effective in removing [...]

Iron-oxide nanoparticle synthesis from liquid spray flames under variable pressure conditions

Hardt S., Wiggers H., Wlokas I., Kempf A., Schulz C., University of Duisburg-Essen, DE

Iron-oxide nanoparticles have been synthesized via liquid-fed flame spray pyrolysis (FSP) under variable pressure conditions. The work focuses on the effect of pressure, precursor flow rate, and flame stoichiometry on particle size, composition, and morphology. [...]
