The biodegradable polymeric PLA-PEG nanoparticles is an efficient delivery system for a chlamydial M278 mucosal nanovaccine that provides protective systemic and mucosal antibody responses in mice

Verma R., Sahu R., Dixit S., Singh S.R., Dennis V.A., Alabama State University, US

The rising concerns relating to the failure of public health programs, relying mostly on antibiotic treatments to control the plethora of disease manifestations caused by Chlamydia trachomatis in humans, strongly begs the urgency for an [...]

Dendrigraft Poly-L-lysine (d-PLL) Coated Gold Nanoparticles in Water for siRNA Delivery to Prostate Cancer Cells

Rahme K., Minassian G., Ghanem E., Souaid E., Guo J., O’Driscoll C.M., Holmes J.D., Notre Dame University (Louaize), LB

In this study we used dendrigraft poly-L-lysine (d-PLL) as a stabilising ligand for gold nanoparticles (AuNPs) in water. The d-PLL generation two (P2) with narrow molecular weight distribution of about 7 KD was obtained by [...]

A Simple Synthesis of Polymer Coated Gold and Silver Nanoparticles in Water for Potential Use in Biomedical Applications

Rahme K., Minassian G., Ghanem E., Sarkis M., Nakhl M., El Hage R., Souaid E., Holmes J.D., Notre Dame University (Louaize), LB

Herein we describe a simple method for the synthesis of highly stable gold (Au) and silver (Ag) nanoparticles (NPs) in water. Ag and Au NPs of different surface charges (positively charged, negatively charged, or nearly [...]

Photoswitching Nanoparticles Enable Innovative Bioimaging Technologies

Wan W., Li A., Washington State Universoty, US

Nanoparticles have evolved to be the carriers of multiple technologies, which garnished unprecedented power in molecular imaging. For example in bioimaging, a single fluorescent probe is usually lost in the ocean of myriad other molecules [...]

Synthesis and Characterization of Magnetite Nanoparticles, Activated Carbon and their Composites

Adegoke H.I., Adekola F.A., Abdul Raheem M.N., University of Ilorin, NG

Magnetite nanoparticle (MNP), Fe3O4 was prepared via co-precipitation method, activated carbon was produced from coconut coir pith through chemical activation process. As coconut coir showed maximum weight loss at temperatures lower than 500°C, it was [...]

Gas phase sodium flame synthesis of non-oxide metallic powders

Abid A., Smith G., Krause M., Yin A., Sungail C., GAM, US

Demand for new high surface area non-oxide materials is growing to support the diverse market such as energy storage, catalysts, electronic materials etc. Tight control of powder purity and flow properties are important parameters for [...]

Graphene-Metal Oxide based Nanocomposites for Supercapacitor Applications

Selvakumar D., Nagaraju P., Jayavel R., Anna University, IN

Two dimensional graphene-based nanocomposites have been synthesized through the modified Hummer’s method and chemical reduction process. Transition metal oxides were decorated on the graphene sheets by in-situ hydrothermal method. The composites were formed with graphene [...]

Electrochemically Exfoliated Graphene: Production and High Performances.

Wang J., Institute of Coal Chemistry, Chinese Academy of Sciences, CN

I’d like to present that graphene flakes have been produced with good properties and potentially used widely through electrochemical approaches. The electrochemically exfoliated graphene-based materials exhibit high performances in thermal management, electrocatalysis, supercapacitor, batteries and [...]

Graphene based core–shell additives for increasing the thermal conductivity of epoxy nanocomposites

Eksik O., Bartolucci S.F., Gupta T., Fard H., Tasciuca T.B., Koratkar N., Istanbul Technical University, TR

We studied novel technique to enhance the thermal conductivity of epoxy nanocomposites using graphene coated poly-methyl-methacrylate (PMMA) balls. PMMA balls with a diameter in the range of 200–300 nm were synthesized using suspension polymerization. These [...]

Graphene Synthesized in the Gas Phase: Research and Applications

Dato A., Harvey Mudd College, US

Pure and highly ordered graphene can be rapidly and continuously produced through the substrate-free gas-phase synthesis method. The single-step process involves sending precursors, such as ethanol and dimethyl ether, directly into atmospheric-pressure microwave-generated argon plasmas, [...]
