Novel Hierarchically Ordered Porous Vanado-Silicate Nanocomposites for the Application in Industrial Catalysis

Howard M., Whittle J., Zhang F., Zhao D., Sen T., University of Central Lancashire, UK

A novel hierarchically ordered porous vanado-silicate nanocompsoites were fabricated with isolated vanadium species with well dispersed state in the porous martrix for the oxidation of bulkier organic molecules i.e cyclooctene for the selective production of [...]

Advances (and limits) in photocatalytic building materials

Diamanti M.V., Politecnico di Milano, IT

Titanium dioxide has often been indicated as emerging technique for environment depollution, specially in urban environments. It can be easily added to building materials, such as concrete or mortar elements, or as coating to any [...]

Luminescent Terbium/Europium chelates-based Silica Nanoparticles : Stability and Incorporation Efficiency measured by Radioactive Probe

Wartenberg N., Raccurt O., Mazzanti M., Imbert D., Bourgeat-Lami E., Commissariat à l’Energie Atomique, FR

We describe an original method based on europium-chelated radioactive measurements to investigate and compare the incorporation (by a reverse microemulsion-mediated sol-gel process without covalent bond) and the stability of two different organolanthanides into silica nanoparticles. [...]

Synthesis of non-oxide ceramic powders by carbothermal reduction of a combustion synthesis precursor

Qin M., University of Science and Technology, Beijing, CN

Tis wrok introduced a novel method for sunthesizing non-oxide ceramic powders by the combination of low temperature solution combustion synthesis (LCS) and carbothermal reduction. Firstly, a homogeneous precursor consisting of fine oxide and carbon particles [...]

A Novel High Yield Process for Gold Sulfide Nanoparticle Synthesis via Shifting Equilibrium of Self-Assembly Reaction

Patel D., James K., Zhang G., Gobin A.M., University of Louisville, US

This project is focused on the scale up of gold-gold sulfide (GGS) nanoparticles with desired near infrared peak (nIR) that can be used for therapeutic applications. By combining published methods for 1-step self-assembly of GGS [...]

Synthesis and characterization of copper oxide decorated zinc oxide nanorods

Lim S.K., Hong S.H., Hwang S.H., Kim H-S, Kim S., Lee D.J., Kim H-S, Kim S., DGIST(Daegu Gyeongbuk Institute of Science & Technology), KR

One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for [...]

One-pot synthesis of monodisperse PbSe quantum dots and graphene oxide nanocomposites

Pan Yi, Lombardi J.R., City College of New York, US

A new, one-pot method to synthesize monodisperse PbSe quantum dots (QDs) and graphene oxide (GO) nanocomposites (GO-PbSeQDs) is reported here. PbCl2 complexed with oleylamine was used as the Pb precursor. Se powder dissolved in long [...]

CdSe Nanoparticles in Silica Matrix by Sol Gel method

Hullavarad N., Hullavarad S., Hullavarad N., Hullavarad S., University of Alaska Fairbanks, US

‘Quantum dots’ or nanoparticles of diverse semiconductor materials are extensively studied because of their interesting size dependent properties. It is further interesting to organize the quantum dots in the form of superlattices thin films, monolithics, [...]

Facile doping of silica nanoparticles with far-red cyanine dyes using the microemulsion method

Nooney R., McDonagh C., Biomedical Diagnostics Institute, IE

We prepared silica NPs doped with two far-red absorption cyanine dyes, FR670 and Cy5, using the microemulsion method. At these wavelengths there is less autofluorescence from biological molecules, solvents and substrates. The effects of changing [...]

Nanogel Star Polymer Nanostructures of Controlled Size, Molecular Architecture and Functionality: No Assembly Required

Miller R.D., Sly J., Lee V.Y., Appel E., Nguyen T., Nunes H., Tjio M., Gomez L., McNeil M., Munninghoff J., Rowan A.E., IBM Almaden Research Center, US

We have developed versatile routes to nanogel core, multiarm star polymeric unimolecular amphiphiles that provides exquisite control over molecular size, polydispersity, chain and periphery functionality which eliminate the dynamic equilibrium associated with polymeric micelles. . [...]
