Lithium selective adsorption on low-dimensional TiO2 nanoribbons

Zhang Q-H, Li S-P, Sun S-Y, Yin X-S, Yu J-G, East China University of Science and Technology, CN

Low-dimensional TiO2-related nanomaterial with high morphology specificity, including nano-tube, -wire, -sheet, -fiber and -ribbon, had attracted particular interest in advanced applications as catalyst, solar-energy conversion semiconductor, gas sensor and electrochemical material, as it was discovered [...]

Interaction of Polyamido-amine (PAMAM) nanoparticles with the glassy carbon supported bilayer lipid membrane

Jadhav S.R., Mark Worden R., Michigan State University, US

Polyamido-amine (PAMAM) dendrimers are hyperbranched polymers with uniform particle size making them ideal monodisperse nanoparticles. PAMAM dendrimers are being pursued as non-viral vectors for gene delivery due to their low immunogenicity and their ability to [...]

Permeability and protein separations: functional studies of porous nanocrystalline silicon membranes

Snyder J., Kavalenka M., Fang D., Striemer C., Fauchet P., McGrath J., University of Rochester, US

We have developed an ultrathin (15nm) freestanding nanoporous silicon based membrane [1]. This new material, termed porous nanocrystalline silicon (pnc-Si), is fabricated using standard photolithography techniques. Pore sizes can be tuned in a thermodynamically driven [...]

Design and Parameters of Cellulose Filter Media with Polymer Nanofiber Layer

Maly M., Petrik S., ELMARCO s.r.o., CZ

Nanofiber polymer layer deposited on regular cellulose filter media usually shifts resulting air filtration parameters of this material several classes higher. Very fine nanofiber web of basis weight of 0.01 gm-2 to 0.1 gm-2 improves [...]

Towards Automation in the Characterization of Nanostructured Materials and Devices

Weishaupt K., Schmidt U., Dieing T., Hollricher O., WITec GmbH, DE

The characterization of nanostructured materials implies knowledge about their chemical and structural properties, leading to a growing demand for characterization methods for heterogeneous materials on the nanometer scale. However, certain properties are difficult to study [...]

Nanostructuring Plastic Displays within the Flexible Electronics Paradigm

Andrews M.P., Frechette P., Fong B., Shih I., Plastic Knowledge (formerly Silk Displays), CA

This presentation describes our advances in fabricating a fully functional color, plastic liquid crystal display that uses an all-inorganic thin film transistor array based on a nanocrystalline II-VI semiconductor. The display itself represents an interesting [...]

Effects of the Building Block on the Morphology and Properties of Porous CdSe Nanostructured Framework

Yu H., Bellair R., Kannan R., Brock S., Wayne State University, US

A major challenge in designing and making potentially valuable nanostructures is to find suitable ways to effectively tune their properties and function. Recent work in our lab has demonstrated a powerful strategy to engineer the [...]

A comparison of boron hydride- and hydrocarbon-based thiol derivatives assembled on gold surfaces

Base T., Bastl Z., Academy of Sciences of the Czech Republic, CZ

Carbon and boron atoms form extensive series of compounds with hydrogen, hydrocarbons and boron hydrides. This contribution deals with the selected thiol derivatives from both groups of compounds. The mutual comparison of these thiol species [...]

Mechanical properties under nanoindents in gold nanoparticles reinforced poly(vinyl alcohol) nanocomposite films

Tripathy P., Mishra A., Ram S., Fecht H-J., Indian Institute of Technology, IN

Free standing films of gold nanoparticles reinforced poly(vinyl alcohol) (PVA) nanocomposite are synthesized by a novel chemical method with selective Au-contents varied from 0.1 to 5.0 wt%. The color change in the Au-PVA nanocomposite films [...]

Mechanical and Electrical Properties of CNT/Inorganic Nanocomposites by Molecular Level Mixing Process

Hong S.H., Korea Advanced Institute of Science and Technology, KR

One of the emerging applications of CNTs is the reinforcement of composite materials to overcome the performance limits of conventional materials. However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix [...]
