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 ...
Processing and Characterization Techniques for a Mica Filled Polymer Composite
(Virginia Tech Department of Materials Science and Engineering, 2015-01-01)
Mica particulates (filler) were combined with polymethyl methacrylate (matrix) to form a polymer matrix ceramic composite (PMCC). Mica concentrations in the range of 10-80 wt% mica with particulate sizes in the range of ...
Developing Functional Inks for Direct-Write Systems
(Virginia Tech Department of Materials Science and Engineering, 2010-03-20)
The field of Flexible Printed Electronics (FPE) carries great potential in reducing manufacturing costs and increasing versatility. The purpose of this research is to explore various ink chemistries and their suitability ...
Journal of Undergraduate Materials Research, Vol. 2 (2006)
(Virginia Tech Department of Materials Science and Engineering, 2006-09-22)
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 ...
The Dynamics of Periodically Forced Prolate Spheroids in a Quiescent Newtonian Fluid with Weak Inertia
(Virginia Tech Department of Materials Science and Engineering, 2010-03-20)
The effects of convective and unsteady inertia on the dynamics of periodically forced neutrally buoyant prolate spheroids in a quiescent Newtonian fluid medium, at low Reynolds numbers have been modeled. The resulting ...
Variations in Hardness and Grain Size with Density for Fully Stabilized Zirconia Sintered Using Microwave Processing
(Virginia Tech Department of Materials Science and Engineering, 2010-03-20)
Densification of ceramic materials with microwave energy is being considered as an alternative means to conventional methods. Using microwave processing for sintering ceramics, many researchers have observed higher densities ...
A Guide to the Calculation of Theoretical Densities of Crystal Structures for Solid Oxide Fuel Cells
(Virginia Tech Department of Materials Science and Engineering, 2006-09-22)
Theoretical density is an important parameter used to estimate the porosity of materials after sintering, especially if the requirements for the materials’ densities are strict, such as in the case of the parts of solid ...
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 ...
A Novel Porous Polymers Manufacturing Technique
