1.  Synthesis of freestanding HfO2 nanostructures 
Nanoscale Research Letters  2011;6(1):294.
Two new methods for synthesizing nanostructured HfO2 have been developed. The first method entails exposing HfTe2 powders to air. This simple process resulted in the formation of nanometer scale crystallites of HfO2. The second method involved a two-step heating process by which macroscopic, freestanding nanosheets of HfO2 were formed as a byproduct during the synthesis of HfTe2. These highly two-dimensional sheets had side lengths measuring up to several millimeters and were stable enough to be manipulated with tweezers and other instruments. The thickness of the sheets ranged from a few to a few hundred nanometers. The thinnest sheets appeared transparent when viewed in a scanning electron microscope. It was found that the presence of Mn enhanced the formation of HfO2 by exposure to ambient conditions and was necessary for the formation of the large scale nanosheets. These results present new routes to create freestanding nanostructured hafnium dioxide.

2.  The Economic Impact of a College of Pharmacy 
Objectives
To quantify the dollar value of economic returns to a community when a college of pharmacy attains its fourfold mission of research, service, patient care, and education.
Methods
United States Bureau of Economic Analyses (BEA) RIMS II input/output analysis and data from student and faculty surveys were used to quantify the economic impact of the University of Tennessee's College of Pharmacy (UTCOP).
Results
The UTCOP's revenue of $22.4 million resulted in an indirect output impact of over $29.2 million, for a total impact of nearly $51.6 million in output (production of goods and services), while supporting 617.4 jobs and total earnings of $18.5 million during the 2004-2005 school year.
Conclusions
Demonstrating the economic value of colleges of pharmacy is critical when seeking support from state legislators, foundations, government agencies, professional associations, and industry. Based on this study, UTCOP was able to report that every dollar the state invests in UTCOP yields an estimated net return on investment of $27.90.
