A new model for toxicity of uranium dust

Zucchetti M., Massachusetts Institute of Technology, US

Depleted Uranium (DU) is mostly composed by the natural radioactive isotope U238 and it is a by-product of the enrichment process, that part of the nuclear reactors fuel cycle that produces the nuclear fuel to [...]

Green Remediation using Renewable Energy and Automation

Ambler M., Weston Solutions, Inc., US

The goal of the project is reduction of contaminants associated with gasoline at a retail fuel station. Groundwater gasoline range organic concentrations at the site were 500 mg/L prior to system startup. Advanced technologies and [...]

Polymer Coated Nickel Ferrite Nanoparticles for High-gradient Magnetic Separation

Alvarez R., Trad T.M., Martirosyan K.S., University of Texas at Brownsville, US

Magnetic separation is a complex physical process in which magnetically susceptible composites is extracted from a liquid mixture using magnetic properties of the substances. Several separation procedures are developed based on magnetic susceptibility, magnetohydrostatic, magnetohydrodynamic [...]

Low Weight, Low Cost Commercial-Scale PV Inverter

Bundschuh P., Ideal Power Converters, US

Ideal Power Converters has developed and patented a new current-modulated electronic power converter topology that reduces the materials, manufacturing, shipping and installation cost of large-scale PV inverters. LCOE is further improved with improved efficiency and [...]

Vertical-Axis Wind Turbines for Powering Cellular Communication Towers

Plourde B.D., Abraham J.P., Mowry G.S., University of St. Thomas, US

A vertical-axis turbine has been designed to power cellular communication towers. The turbine’s design is specifically focused on providing continuous power to manage the tower’s electronics without interfering with the tower structure. The design of [...]

A Smarter Grid enables Communal MicroGrids

Mohn T., General MicroGrids, Inc, US

As policy makers seek to integrate a serious sociological and environmental issue into energy production, the typical utility is faced with not only technology upgrades, but also dealing with new systemic events that occur far [...]

High-Power-Density Miniscale Renewable Energy Systems

Lyshevski S.E., Rochester Institute of Technology, US

This paper reports design, analysis, evaluations and characterization of miniscale self-sustained power generation systems. Our ultimate objective is to guarantee highly-efficient mechanical-to-electrical energy conversion, ensure premier wind- or hydro- energy harvesting capabilities, enable electric machinery [...]

Grid-Connected Photovoltaic System Parity with PJM Generation

Jansson P.M., Schmalzel J.L., Barreiro C., Rowan University, US

This research provides compelling economic and technical analysis of photovoltaic (PV) system performance in New Jersey and contrasts the generation availability marginal pricing on the world’s largest regional transmission organization (PJM). This analysis indicates that [...]

Design and Development of Photovoltaic Systems

Lyshevski S.E., Rochester Institute of Technology, US

Significant efforts have being concentrated on low-cost, efficient, renewable, sustainable, safe and portable energy sources and systems. Recently, different photovoltaic technologies, solar cells, energy storage and power electronics energy solutions have been emerged and under [...]

Characterization of Microcrystalline and Amorphous Thin Film Silicon Devices with Raman Spectroscopy

Wall M., Hodkiewicz J., Thermo Fisher Scientific, US

Raman spectroscopy is highly sensitive to even slight changes in morphology of highly symmetrical, covalently bonded materials making it an ideal technique to characterize Silicon films. Furthermore, Raman spectroscopy is relatively insensitive to glass making [...]
