Synthesis of Janus Nanorods for Assemblies of Thermoresponsive Rod Pairs

MacCuspie R.I., Park K., Naik R., Vaia R.A., Air Force Research Lab, US

Janus particles offer unique functionality; for example micron-scale Janus spheres are used for electronic paper. At the nanoscale, reproducible, scalable fabrication of Janus particles is one of the key enabling technologies for “bottom-up” assembly processes. [...]

Scattering properties of dense clusters of nanoparticles

Lattuada M., Ehrl L., Soos M., Morbidelli M., ETH Zürich, CH

The use of light scattering or laser diffraction techniques to characterize dense clusters such as those generated in shear induced coagulations is highly desirable. However, a major obstacle in the effective utilization of this technique [...]

Computational and experimental studies of non-metal-terminated surfaces of anatase and rutile TiO2

Yang H.G., Sun C.H., Qiao S.Z., Zhou J., Smith S.C., Cheng H.M., Lu G.Q., University of Queensland, AU

The structures and free energies ( ) of low index surfaces of anatase and rutile TiO2 terminated by nonmetals (H, B, C, N, O, F, Si, P, S, Cl, Br, and I) have been studied [...]

Biphenyl-functionalized Ethane-silica Hybrid Materials with Ordered Hexagonal Mesoporous Structure

Virtudazo R., Magdaluyo Jr E., dela Cruz L., Castriciones E., Mendoza H., University of the Philippines, PH

A biphenyl-containing hybrid organic-inorganic mesoporous materials have been synthesized and characteized. The synthesis was done via surfactant-templated polymerization of 4,4’-bis(triethoxysilyl)biphenyl and 1,2-bis(triethoxysilyl)ethane under basic condition. The composition, structure and morphology of the mesoporous materials were [...]

Structure of Ni nanoparticles/TiO2 films prepared by sol-gel dip-coating

García-Murillo A., Ramírez-Meneses E., Ramírez-Salgado J., Sandoval-Robles B.G., Montiel-Palma V., Dorantes-Rosales H., Del Angel-Vicente P., Cicata - IPN Unidad Altamira, MX

Titania thin films were synthesized by sol-gel dip-coating method with metallic Ni nanoparticles from an organometallic precursor. Titania matrix and Ni nanoparticles were prepared separately. Titania precursor solution was prepared mixing titanium isopropoxide in isopropanol [...]

Glycerol Assisted Polymeric Precursor Route for the Synthesis of Nanocrystalline LiCoO2 Powders

Vivekanandhan S., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

LiCoO2 with Layer structure has been used as a cathode material in lithium batteries. Recently, it is found that the nanostructured LiCoO2 powders exhibit an enhanced electrochemical performance compared to their bulk. Physiochemical properties of [...]

Free- standing SnO2 nanoparticles synthesized by hydrothermal route

Fernández-Osorio A., Vázquez-Olmos A., Sato-Berru R., Casas-Gutiérrez D., Universidad Nacional Autonoma de Mexico, MX

Tin oxide with rutile-type crystalline structure is a n-type wide band gap (3.5 eV) semiconductor that presents a proper combination of chemical, electronic and optical properties that make it advantageous in several applications. Due to [...]

Silver nanoparticles synthesized on titanium dioxide fine particles

Niño-Martínez N., Martínez-Castañón G.A., González-Hernadez J., Ruiz F., Universidad Autonoma de San Luis Potosi, MX

Silver nanoparticles with a narrow size distribution (20 nm mean size) were synthesized over the surface of two different commercial TiO2 particles using a simple aqueous reduction method. The reducing agent used was NaBH4; different [...]

Production of Nanoparticles Sizes of Active Pharmaceutical Ingredients (API) by Wet Comminution with DYNO-MILL

Goldberg S., Roskosch N., W.A. Bachofen AG & Glen Mills Inc., US

The production of nanoparticles in the size range of 13nm has been achieved using the DYNO®-MILL bead mill. Active Pharmaceutical Ingredients (API) are able to be absorbed by the body’s cells when of a size [...]

In-situ incorporation of Pd-MPTES complex in nanostructured silica

García Martínez J., Carrillo A.I., Linares N., University of Alicante, ES

Recently, we described a simple method to incorporate metal nanopaticles in porous materials by functionalization of nanoparticles with trialkoxysilanes. This strategy is based on three steps: first, the metal nanoparticles were produced by controlled reduction [...]
