Raney Nickel Catalyst – A Molecular Modeling Study

Schweizer S., Chaudret R., Spyriouni T., Low J.J., Subramanian L., Scienomics, US

Porous solid materials are central to various application areas. Due to their specific structural features, they are often used in catalysis, as storage material for hydrogen or small molecules, or as molecular sieves, but they [...]

Study of a Power Source Based on Low Energy Nuclear Reactions (LENRs) Using Hydrogen Pressurized Nanoparticles

Miley G.H., University of Illinois, US

We are studying anomalous heat, attributed to Low Energy Nuclear Reactions (LENRs), generated from metal alloy nanoparticles loaded with hydrogen (or deuterium) through pressurizing the vessel containing the particles [1]. The primary result thus far [...]

Removal of Water Contaminants Using Nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

Propanil, Diuron, Simazine, and Metolachlor are widely used as herbicides and pesticides in California agriculture and across the U.S., and are considered to pose a significant threat to water contamination by transporting chemicals into surface [...]

Uniform Spray-based Large Area Nanoparticle Coating at Nanometric Thickness

Rukosuyev M., Lee P-C, Jun M.B.G., Purdue University, US

Nanoparticle deposition or coatings have drawn significant attention of many researchers and companies because of their potential use in a broad range of applications. For example, nanoparticle coatings can be used to create conductive, catalytic, [...]

Numerical and Experimental Investigation in Replicating a Micro-Featured Surface with the Injection Molding Process

Rajhi A., Jaafar I.H., Coulter J.P., Lehigh University, US

This paper describes current efforts to numerically and experimentally investigate micro and nanoscale features replication using the injection molding process. A silicon (Si) insert with micro–features is fabricated via photolithography followed by deep reactive ion [...]

Feedback Process Control for Nano-manufacturing of Semi-conductor Circuits

Kohn W., Zabinsky Z.B., Atigeo, LLC and CUNY Graduate Center, Computer Science Department, US

We develop a feedback process control to realize 3-D circuits with a 2 to 4 nanometer footprint, using a heavily modified ink-jet based nano-manufacturing facility that includes actuator controls driven by pulsed femto lasers. At [...]

Rapid Design, Development and Deployment of Materials for Extreme Environments

Conrad R., Mollot D., U.S. Department of Energy, US

The availability of low cost, durable metal alloys is a foundational requirement for achieving many of the Nation’s targets for affordable, efficient power production. This need for high-performance alloys is particularly manifest as an enabler [...]

Thousand-fold speedup of discrete-particle-based computer-aided reactor design and scale-up

Lu L., Benyahia S., National Energy Technology Laboratory, US

Particulate matter is the second most manipulated material in industry after water and has been observed and studied by scientists and engineers since the earliest of human civilization. In fact, we commonly distinguish between the [...]

Architected Microlattice Materials by Self-Propagating Waveguide Processing

Corrion A.L., Clough E., Eckel Z., Hundley J., Roper C., Schaedler T., HRL Laboratories, LLC, US

HRL Laboratories has developed a platform technology to rapidly and scalably manufacture architected lattice materials based on polymers, metals, and ceramics suitable for a variety of applications. Architected materials with periodic cellular structure exhibit unprecedented [...]

Characterization of Nanosilica Release from a Weathered Nanosilica/Polyurethane Coating

Hsueh H-C, Lu C-Y, Huang S-R, Cheng Y.L., Jacobs D., Rabb S.A., Yu L.L., Nguyen T., Sung L., National Institute of Standards and Technology, US

Polymer nanocoatings are widely used outdoor environment because the excellent properties. The addition of nanoparticles can improve performance properties including mechanical, electrical, chemical and ultraviolet resistance. However, because polymer in coating are susceptible to degradation [...]
