Measurement of hydrogen in Ti-Al alloy by RBS

Lead Institution
University of Idaho
Principal Investigator
Baburaj Eranezhuth
Project type
Exploratory Research
Although there are hundreds of intermetallic compounds, only a few are being developed as structural materials for a broad range of applications. Among the titanium aluminide intermetallics, Ti3Al…

Coal Surface Charging Property Characterization

Lead Institution
University of Arkansas, Little Rock
Principal Investigator
Malay Mazumder

The goal is to advance the fundamental understanding of the electrostatic properties of coal and mineral particles and apply to advanced technology for dry coal beneficiation and mineral separation…

Reaction mechanisms for silicate mineral dissolution

Lead Institution
Virginia Polytechnic Institute
Principal Investigator
J Rimstidt
Project type
Exploratory Research
The rates of reaction between silicate minerals and glasses and aqueous solutions is of great scientific and technological interest. For example, these reaction rates determine how fast carbonic acid…

Identification of biogenic Fe(11) oxides resulting from microbial reduction.

Lead Institution
Indiana University - Bloomington
Principal Investigator
Flynn Picardal
Project type
Exploratory Research
The objectives of this project are to: (i) examine the effect of iron oxide mineralogy on iron mineralization induced by microbial reduction of that oxide, (ii) determine the mechanism(s) by which…

Reactivity of bridging Oxygens on the Pyrophyllite 110 and 1-10 edge faces
