Transfer of asymmetric free-standing TiO2 nanowire films for high efficiency flexible dye-sensitized solar cells

Xue Z., Wang L., Liu B., National University of Singapore, SG

A free-standing TiO2 nanowire thin film was prepared using the doctor-blade method. The film is composed of big and small nanowires on each side. The big nanowires have the functions of weakening adhesion to its [...]

Characterization of Solar Grade Silicon Contaminants

Mount G.R., Wang L., Putyera K., Lepage M., Evans Analytical Group, US

The term ‘Solar Grade Silicon (SoG)’ has been used for many years but until recently, there were no specifications as to what this actually meant. Without specifications, suppliers of silicon have been using ‘number of [...]

A Regional Model for Threshold Switching in Phase Change Memory

Wang L., Peking University Shenzhen Graduate Schoo, CN

In this paper, a regional model for threshold switching is presented based on the space charge effect in Phase Change Memory (PCM). In this model, the PCM unit is divided into two parts according to [...]

Tuning the Gas Pressure Discharge of Nanoenergetic materials by Boron and Carbon Nanotube Additives

Martirosyan K.S., Wang L., Luss D., University of Texas at Brownsville, US

Thermite reactions are highly exothermic and may rapidly release high amount of stored chemical energy in the form of heat, light and wave. Nanothermite formulations that use aluminum or magnesium as the reducing agent and [...]

Development of nanoenergetic materials based on Al/I2O5 system

Martirosyan K.S., Wang L., Luss D., University of Houston, US

This report presents a novel nanoenergetic system based on iodine oxide and aluminum thermite reaction and the study of their gas generation and thermal wave behavior during the detonation. The ignition of homogeneous mixture of [...]

Fabrication of Bismuth Trioxide Nanoparticles for Gas-Generators Application

Martirosyan K.S., Wang L., Vicent A., Luss D., University of Houston, US

Nanoenergetic materials release significant amount of energy at a higher rate and have a potential for various military applications. These systems lead to a fast propagation of a reaction front through the solid reactant mixtures. [...]

Light-Off Characteristics for Diesel Oxidation Catalysts in Monolith Reactors: Effects of Catalyst Distribution Schemes

Kapur N., Wang L., Truex T.J., Fujdala K.L., Nicholas J.B., Nanostellar Inc., US

In order to fulfill the EPA emission standards for diesel automobiles, platinum-coated catalytic converters are commonly employed for CO and hydrocarbon oxidation. Mathematical models for monolith reactors can potentially shorten catalyst development time and provide [...]

An Embedded Atom Method for Alloy Nanoparticles

Shan B., Hyun J., Wang L., Yang S., Kapur N., Nicholas J.B., Nanostellar Inc., US

We present the development and application of a high-accuracy embedded atom method (EAM) potential for the simulation of metal alloy nanoparticles. The potential was parametrized by a large set of density functional theory (DFT) calculations [...]

Delivery of Shiga Toxin 1 A Subunit into Epithelial Cells Using Silica-Based Nanowires

Kwon N.H., Beaux M., Sheng H., Ebert C., Wang L., McIlroy D.N., Hovde C.J., Bohach G.A., University of Idaho, US

Silica-based nanowires were used to introduce the Shiga toxin 1 A subunit (StxA1) into bovine and human epithelial cells. We extended our previous technology which employs fibronectin (Fn) as a ligand to induce integrin-mediated uptake [...]
