Highly Spherical Gold Nanoparticles by Laser Pulse Heating

Cavicchi R.E., Meier D.C., Presser C., Guha S., National Institute of Standards and Technology, US

Methods continue to be developed for improving the size and shape uniformity of Au nanoparticles (NP), however, fabricated NPs tend to be faceted and not highly spherical. We present results that show that the faceted [...]

Synthesis of Micrometric Single Crystalline Magnetite with Superparamagnetic Properties for Biomedical Applications

Chirita M., Kiss M.L., Ieta A., Grozescu I., State University of New York at Oswego, US

There are no reports on the synthesis of single crystalline micrometric magnetite with superparamagnetic behavior. The literature mainly refers to micrometric particles obtained by nanoparticle agglomeration. The major disadvantage of magnetic microparticles composed of clusters [...]

PLA-PEG as a delivery system for a Chlamydia trachomatis subunit vaccine

Dixit S., Singh S.R., Yilma A.N., Agee R., Dennis V.A., Alabama State University, US

We hypothesize that M287 encapsulated in PLA-PEG will provide for its slow controlled release and thus enhance its capacity to induce immune responses in mice.

Multifunctional plasmonic nanoparticles for biomedical applications

Sotiriou G.A., Pratsinis S.E., ETH Zürich, CH

Plasmonic nanoparticles play an important role in biomedical applications today as they can serve as superior optically-stable bioimaging agents, be employed in biosensor devices for the early diagnosis of diseases, and exhibit promising results for [...]

Synthesis of Air-stable Aluminum Nanoparticles capped with 1, 2 -Epoxy-9-Decene/ Methyl Methacrylate and Poly (Methyl Methacrylate)

Patel A., Guliants E.A., Bunker C.E., Jelliss P.A., Buckner S.W., Saint Louis University, US

Aluminum metal, with its light weight, high energy density, and ready availability is particularly valued in energetic application such as fuel additives. Aluminum nanoparticles (Al NPs) offer the advantage of accessing this high energy content [...]

Capping and Passivation of Aluminum Nanoparticles: Aluminum-Induced Alkene Polymerization

Thomas B.J., Lloyd E., Guliants E.A., Bunker C.E., Jelliss P.A., Buckner S.W., Saint Louis University, US

Aluminum nanoparticles (Al NPs) have long been utilized for high-density energy storage and small-scale hydrogen production. The enthalpy of reaction for the formation of aluminum oxide (-1675.7 kJ mol-1) is a major reason for aluminum’s [...]

Polymerization Passivation Strategies for the Stabilization of Energetic Aluminum Nanomaterials

Jelliss P.A., Thomas B.J., Patel A., Lloyd E., Guliants E.A., Bunker C.E., Buckner S.W., Saint Louis University, US

We are developing aluminum nanoparticle (Al NP) passivation strategies based on our established protocols for polymerization of epoxide molecules with a view to fabricating air-stable Al NPs with long shelf-lives. Additionally we have discovered that [...]

Preparation of size-controllable (Cu-ZnO)@C core- and yolk-shell nanoparticles

Hong C.-I., Kang H.Y., Chang F-C, Wang H.P., National Cheng Kung University, TW

Size-controllable Cu-ZnO@C core-shell nanoparticles having diameters of 7-20 nm were prepared by carbonization of Cu2+- and Zn2+-CD (Cu-to-Zn ratio=0.1-1) at 343-573 K for 2 hrs. By XRD, the major compounds in the Cu-ZnO@C core-shell nanoparticles [...]

Sb2S3 Nanocrystals in glass

Mishra R.K., University of Delhi, IN

In this work conventional quench method was adopted to fabricate Sb2S3 nanocrystals in glass. To ensure proper mixing and homogeneity of the composition the base glass constituents SiO2, B2O3, Na2O, K2O, ZnO were mixed by [...]

New Functions of Polyolefin for Manipulated Iron Oxide Nanostructure Synthesis

Guo Z., He Q., Wei S., Lamar University, US

In this work, a novel function of PP-g-MA has been successfully explored. Specifically, PP-g-MA has been selected to replace the conventional fatty acid surfactants to fabricate stable iron oxide colloids. The fabrication process was carried [...]
