Synthesizing and Consolidation of Mechanically-Induced Solid-State Reacted Ti50C50 Nanopowders and Subsequent Consolidations
Sherif El-Eskandarany M., Al-Hazza A., Shaban E., Alduweesh A., Al-Rowayeh A., Kuwait Institute for Scientific Research, KW
In contrast to the industrial approach for preparing such important materials, we have succeeded to synthesize a single phase of Ti50C50 nanopowders, using high-energy ball milling technique. The ball milling procedure took place at ambient [...]
Influence of applying the additional continuous laser on photoluminescence properties of silicon nanoparticles produced by laser ablation in liquid
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
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
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
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
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
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
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 [...]
