Particles as Protein Markers: Nanoscale Microscopy Towards Picoscale

Shriniwas B.D., Sharma A., Sharma R., Sharma A., Sharma R., Chen C-J., Baile V.V., Raghukumar V., RTM Nagpur University, IN

The present report shows the emerging trend of picotechnology in bioengineering, Heteropneustes fossilis fish protein characterization by PAGE-gel electrophoresis, 10-100 nm nanoadducts by electron microscopy with possibility of nanogel-peptide(polyacylate-polyethylene-iron oxide) adducts as predictors of fish [...]

Ferrite-Silica-Insulin Nanocomposites (FeSINC) for Glucose Reduction

Dwivedii N., Arunagirinathan M.A., Sharma S., Bellare J., Indian Institute of Technology - Bombay, IN

Silica-insulin nanocomposite (SINC) and ferrite coated SINC (FeSINC) prepared by polyelectrolytic condensation of silica precursor on insulin were studied to control the glucose level. Silica precursor which has a negative charge binds to insulin that [...]

Synthesis and Characterization of Novel ZnO-Whey Protein Nanocomposite at Low Temperature

Shi L., Zhou J., Gunasekaran S., University of Wisconsin-Madison, US

The incorporation of nanocrystalline ZnO into whey protein to form nanocomposite will possess the unique functionalities and potential applications in material science and food sciences. Herein we synthesized nanocrystalline ZnO particles coated with whey protein [...]

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 [...]
