Influence of applying the additional continuous laser on photoluminescence properties of silicon nanoparticles produced by laser ablation in liquid

Popovic D.M., Faculty of Physics, University of Belgrade, RS

Silicon nanoparticle (Si-NPs) is attracting attention of authors in numerous fields of science. The photoluminescence properties of Si-NPs make them a candidate for biomaging applications. The one of the most promising and the simplest method [...]

Synthesis and Characterization of a Novel Palladium Nanostructured Ensemble Supported in Anodized Alumina Membranes for Hydrogen Sensing Applications

Méndez-Colberg H.G., Martínez-Iñesta M.M., University of Puerto Rico, Mayaguez Campus, US

A Pd/Anodic alumina membrane (AAM) ensemble was formed by using Solid State Reduction. The ensemble consisted of Pd thin films on both sides of the AAM with connecting nanowires as evidenced with Scanning Electron Microscopy [...]

Microwave Initiated Nucleation for the Synthesis of High Quality Nanocrystalline Quantum Dot Materials

Kim K-J, Chang C.H., Haben P.M., Peterson D.A., Novet T.E., Schut D.M., Shoei Electronic Materials, Inc., US

The colloidal synthesis of nanoparticles, specifically quantum dots, may occur through either a kinetically dominated process where nucleation proceeds rapidly followed by growth via coalescence of nucleates to form larger nanoparticles, or through a thermodynamically [...]

Evaluation of the Potential Synergistic Antimicrobial Effects Observed using Various Combinations of Chemical Agents (Nanoparticled and Non-Nanoparticled) on a Selected Panel of Cheese Derived Microorganisms

O’ Callaghan K.A.M., Kerry J.P., University College Cork, IE

The aim of the this study was to examine the antimicrobial effectiveness of a number of agents (nanoparticled and non-nanoparticled) applied individually and in combination to cheese derived cultures to determine their suitably as active [...]

CO2 reforming of CH4 by the combination of dielectric barrier discharge plasmas and zeolite catalysts

Nguyen H.H., Kim K.S., Kangwon National University, KR

Dry reforming of two green-house gases (CH4 and CO2) to convert to syngas (mixture of CO and H2) has gained deep research interests lately. Several technologies were proposed to convert the CO2 and CH4, such [...]

Development of a Platinum Nanoparticle based Microcombustor Power Device

Bakrania S., Rowan University, US

Microcombustors coupled with thermoelectric devices have the potential to provide a prolonged power source for portable devices as opposed to conventional batteries due to significantly higher energy densities. Recharging then can be easily achieved by [...]

A Comparative Study on Sorption of As (V) ions on Hematite, Goethite and Magnetite Nanoparticles

Adegoke H.I., Adekola F.A., Fatoki O.S., Ximba B.J., University of Ilorin, NG

Hematite (-Fe2O3), magnetite (Fe3O4) and goethite (-FeOOH) nanoparticles were synthesized by transformation of ferrihydrite and precipitation methods, this materials were used for the removal of arsenic (V) ions from aqueous solution. The synthesized nanoparticles were [...]

Monodisperse Thermo-responsive Composite Microgels with Core-shell Structure based on Au@Ag Bimetallic Nanorod as Core: Fabrication and Application in SERS Substrate

Dong X., Zha L.S., Donghua University, CN

In summary, monodisperse Au@Ag bimetallic nanorod is encapsulated by crosslinked poly(N-isopropylacrylamide) (PNIPAM) to produce thermo-responsive composite microgel with well-defined core-shell structure (Au@AgNR@PNIPAM microgel) by seed-precipitation polymerization method using butenoic acid modified Au@AgNRs as seeds. Their [...]

Rapid and Controlled Transition of Magnetic Nano- to Micro-particles: A Useful Feature for Bioseparations

Nehilla B.J., Schulte T.H., Nexgenia, Inc, US

This work describes the use of stimuli-responsive polymers to control the transition of magnetic nanoparticles (mNPs) to magnetic microparticles. Compared to magnetic microparticles, mNPs are advantageous for bioseparations (e.g., immunoassays, immunoprecipitations) for two reasons. They [...]

Toxicity and Pharmacokinetics of uPAR-targeted Human ATF-conjugated Iron Oxide Nanoparticles Following Systemic Delivery in Rhesus Monkey

Chen Y., Gao F., West China Hospital, Sichuan University, CN

Increasing evidence support the potential of a novel cell surface receptor-targeted MRI nanoprobe produced by conjugating a recombinant peptide amino-terminal fragment (ATF) of urokinase plasminogen activator (uPA) to magnetic iron oxide nanoparticles (IONP) in targeted [...]
