Inclusion of Electromagnetic Stress to explain Lithiated Silicon Nanowires

Boone D., Nanoscience Research Institute, US

Abstract: This study considers the electromagnetic stresses and simulates the lithium insertion into a silicon nanowire. The resulting model uses a multi-physics approach to explain the two detrimental effects that could result during the lithiated [...]

Super-capacitor-like Structure for Fission-Fusion Direct Nuclear Energy Conversion

Popa-Simil L., LAOS - Los Alamos Academy of Sciences, US

Direct nuclear energy conversion system uses nano-hetero-structures that harvest the nuclear particles energy, charging a structure resembling a super-capacitor, that discharges releasing it as electric energy. The nano-structure design uses heterogeneity, in order to create [...]

An Anti-reflective and Anti-Soiling Coating for Photovoltaic Panels

Xu Q.F., Zhao Y., Kujan B., Lyons A., ARL Designs LLC, US

Photovoltaic panels face two major challenges in maximizing and maintaining their electrical output – reflections and soiling of the outer glass surface. To address these challenges, we developed a durable, transparent high-performance polymeric coating on [...]

Nuclear Reaction Control and Shielding Systems based on Radiation Guiding in Active Nano-Structures

Popa-Simil L., LAOS - Los Alamos Academy of Sciences, US

The actual nuclear reactors are using heavy concrete shielding, in order to reduce the radiation outside the active zone. The main radiation attenuation method is called mass-attenuation, because no matter (with some approximation) what material [...]

Radiation-Damage Robust, Engineered, Self-repairing Meso-Materials

Popa-Simil L., LAOS - Los Alamos Academy of Sciences, US

Nuclear power is one of the most compact, long lasting and might be the most safe and environmentally friendly energy source if it might be done right, by achieving the harmony between the nuclear reactions [...]

Aerosolization of Carbon Nanotubes Using an Acoustic Generator: Particle Generation and Properties

Ku B.K., Eileen Birch M., CDC/NIOSH, US

With increasing applications and global production of carbon nanomaterials, there is a growing concern about workplace exposure. The National Institute for Occupational Safety and Health (NIOSH) has recommended a working lifetime exposure limit (REL of [...]

A Framework for Identifying Sustainability Performance Targets for Nanomaterials

MacCuspie R.I., Micher L., Nance J., Watkins J., Hyman H., Srinivasan S., Dhau J., Yakymyshyn C., Drake C., Florida Polytechnic University, US

A current challenge facing the application of nano-enabled products is how to evaluate sustainable solutions and develop performance criteria? This work describes the application of an Input-Process-Output (IPO) model as a framework for a life-cycle [...]

Dose- and Time-dependent Effects of Sub-chronic Functionalized MWCNT Exposure on Human Mesothelial Cell Neoplastic Transformation Potential

Stueckle T.A., Davidson D.C., Derk R., Gracheck P., Wu N., Rojanasakul Y., Wang L., National Institute for Occupational Safety and Health, US

Multi-walled carbon nanotubes (MWCNTs) are characterized by asbestos-like fiber morphology and surface chemistries. Physicochemical properties of MWCNTs that influence pleural mesothelioma potential are unknown, but critically needed to enhance safe-by-design nanotechnology. We hypothesized that surface [...]

Characterization of Nanoparticles in Wood Coating Stains and OSHA HazCom Compliance

Saldivar A., Burrelli L., AMA Analytical, Inc., US

Recent marketing of manufactured products for the construction trades has touted the use of engineered nanoparticles in there formulations. For this study, commercially available wood waterproofing stains were obtained that specifically identified “Nano Particle Technology” [...]

New Insights into Microstructure, Rheology & Molecular Level Structural Changes During Self-Assembly & Gelation in Complex Fluids Through Combined DLS-Optical Microrheology-Raman Spectroscopy

Amin S., Blake S., Kidder L., Lewis E.N., Kenyon S., Malvern Instruments, US

Soft Matter/Complex fluid systems are ubiquitous across a range of industrial and consumer sectors. In many instances the final product format of these complex fluids are gels or soft solids and the processing and product [...]
