Biocompatibility and Hardness of Ti-Hf and Diamond-like Carbon Coatings for Orthopedics
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
Every year, about 300,000 total hip replacement (THR) surgeries are performed in the United States.The typical lifespan of an implant ranges between 10 and 20 years, with implant failures largely due to materials issues ...
Solar Houses: You know you want one
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
Amidst an unceasingly intricate political agenda lies what many consider a grave and often ignored issue:global warming.It would be naïve to overlook the current international political and financial demands, but few can ...
Ruthenium Coordination Chemistry: Implications for Directed Carbon Nanotube Assembly
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
Ruthenium coordination chemistry is studied for its usage as a building block for constructing supramolecular coordination complexes.Our laboratory focuses on how nanometer sized ruthenium structures interact with single ...
Evaluation of Bearing Steel Corrosion in Oil Contaminated with Synthetic Seawater
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
Lubricant systems in military aircrafts, operating in marine environments, experience corrosion due to seawater contamination.In particular, low chromium martensitic bearing and gear steels are susceptible to pitting ...
Statistical Analysis of Impedance Data for Jet Turbine Oil Additives
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
A gold, parallel-plate capacitor test cell was used to make electrochemical impedance spectroscopy (EIS) measurements on high resistivity gas turbine engine oil as a function of the oil additive type.The additive effects ...
The Effect of Cornstarch Levels on the Surface Quality of Extruded Soy Protein Plastic
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
The ratio of soy protein isolate to cornstarch was studied in the extrusion of four different formulations of soy protein plastic in order to qualitatively examine the surface quality upon extrusion.Levels of glycerol and ...
Structural Assessment of an Internal Fixation System for a Forearm Long Bone Mid-shaft Fracture
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
A novel low cost manufacturing method for bone replicas is developed in order to provide cross sectional geometry for 3-D modeling.A Finite Element Analysis (FEA), based on this geometry, is used to predict stress distributions ...
Characterization of Electrolessly Plated Graphite Foams with Particle Additions
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
With a low density and high bulk thermal conductivity, graphite foams are ideal for thermal management systems such as computer heat sinks, radiators, and heat exchangers.Previous work has shown it is possible to improve ...
Journal of Undergraduate Materials Research, Vol. 3 (2008)
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
The Journal of Undergraduate Materials Research (JUMR) is a student-run scientific journal dedicated to research performed by students in materials science and related fields. The primary goal of this journal is to provide ...
DISCOVERIES AND BREAKTHROUGHS INSIDE SCIENCE: Bringing science from the laboratory to the living room
(Virginia Tech Department of Materials Science and Engineering, 2008-03-20)
Have you ever kicked back to watch your favorite sciencebased TV programming and had the thought, “That’s not so hard, I could do that.” With the help of a partnership between the National Science Foundation (NSF), the ...
