On September 26, 2002, NASA announced that a consortium of six universities including: The University of Maryland, Virginia Tech, The University of Virginia, North Carolina A&T State University, North Carolina State University, and Georgina Tech had submitted the winning proposal for a National Institute of Aerospace. The Institute began formal operations in January of 2003 in Hampton, VA, and its mission included research, education, outreach, and technology transfer. One important focus of the NIA was to stimulate research among its member universities of potential benefit to NASA and to develop additional partnerships to further NIA focus areas. The work described in this paper is such an activity in bio-inspired actuator materials. This work was originally advocated and developed at Inha University, and it is being extended by teams from Inha University, North Carolina A&T State University, and NASA Langley so that the potential for these actuators as devices for special applications is better understood. This paper focuses on important performance characteristics of electro-active paper (EAPap) actuators and the potential of thes actuators to propel autonomous devices. EAPap is a paper that produces large displacement with small force under an electrical excitation. EAPap is made with chemically treated papers with electrodes on both outer surfaces. When electrical voltage is applied to the electrodes, a tip displacement is produced. One drawback in such actuators is that the actual power produced is variable, and the displacement is relatively unstable. Further, the performance tends to degrade in time and as a function of how the papers are processed. Environmental factors also impact the performance of the product including temperature and humidity. The use of such materials in ambulatory devices requires attention to these concerns and further research is needed to find what initial applications are most congruent with EAPap performance and service lift. In this paper, we have extended the knowledge base of EAPap to include additional ranges of temperature and humidity. We have also looked beyond the current tests on cantilevered beam actuators to segmented plate sections and have tested the ability of these actuators to perform as oscillatory devices both in and out of phase, and to chart their performance vs. time humidity and temperature thus emulating a rudimentary wing or walking assembly.

College Team

If there was any college team that could take the NCAA title from UCLA, it seemed likely that would be one of the talented squads from the Atlantic Coast Conference (ACC). Three teams were especially talented. The University of Maryland, coached by Charles “Lefty” Driesell, billed itself as the UCLA of the East. Coach Dean Smith’s University of North Carolina was a proven team. And North Carolina State University, coached by Norm Sloan, was deep in talent and desire.

The IUPAC Secretariat office has been located in the Research Triangle Park (RTP) since May 1997, following its relocation from Oxford, England after 29 years. The office was housed in a small building right in the center of RTP, which is one of the most prominent high-technology research and development centers in the USA, centrally located near major universities, including Duke University in Durham, the University of North Carolina at Chapel Hill, and North Carolina State University at Raleigh.

Etched Membrane

This article focuses on research on a new member developed, which if textured on the nanoscale will let fuel cells triple the current they can carry. Joseph M. DeSimone, a professor of chemistry and chemical engineering at the University of North Carolina in Chapel Hill and at North Carolina State University, said he has found a way to give fuel cell membrane some texture and more than triple its conductivity. DeSimone and his team have managed so far to increase the surface area by more than seven times, which means seven times the performance, and DeSimone said he may be able to bring that multiple up to as much as 50. The nano-etched membrane is a liquid polymer, so a fuel cell could be built from the outside in. DeSimone also hopes to increase the material’s performance in humidity and test how it responds to a cycle of low and high humidity.

A very successful project at N. C. State University began in 1983, with the first N. C. Landscape and Turfgrass Field Day. The Field Day is co-sponsored with the N. C. Landscape Contractors Association and the Turfgrass Council of North Carolina. The Field Day is an excellent opportunity for industry to visit with faculty and observe research projects and extension demonstrations. Over the years the attendance has grown to over 1200 paid attendees. The Field Day is actually divided into four separate functions: 1) Educational Field Day, 2) Product and Equipment Field Day, 3) Turf Workshops, and 4) Construction Workshops. The Extension and Research projects benefit financially from this endeavor. Any projects from the Field Day are given back to the University. This typically is about $4000.00. The Field Day is held the third Wednesday in May, rain or shine.

Regional cooperative efforts such as the Southern Association of Agricultural Experiment Station Director's Advisory Committees, Development Committees, Multi-State Research Fund supported projects, and Southern Extension/Research Activities Information Exchange Groups have been in existence and have been successful for many years. However, there are opportunities and compelling circumstances for more intensive regionalized efforts, including multi-state faculty positions and multi-state cooperatives. The University of Georgia is involved in three multistate horticulture faculty positions—an orchard floor management specialist (shared with Clemson University and North Carolina State University), an apple research position (shared with Clemson University, North Carolina State University, and The University of Tennessee), and an apple extension specialist (shared with The University of Tennessee)—and one multi-state cooperative, the Southern Region Small Fruit Consortium (supported by Clemson University, North Carolina State University, The University of Georgia, and The University of Tennessee). Justification for these regional efforts includes the following: 1) federal legislation now mandates multi-institutional and integrated (research and extension) activities; 2) state boundaries form artificial barriers that are transparent to clientele groups, problems, and solutions; 3) decreasing state budgets have resulted in faculty and staff reductions at many institutions, with a subsequent decline in services to clientele groups; and 4) in times of limited funding, universities must focus on areas of excellence and collaborate with other institutions to fill in the remaining gaps. Benefits we have realized from these efforts include the following: 1) better service for minor commodities; 2) better educational programs due to larger venues and pooled overhead funds; 3) enhanced communication among institutions leading to increased cooperative efforts in other areas; and 4) reduced duplicity among institutions resulting in freed up resources to address other high priority areas. There are challenges unique to regional cooperatives: 1) travel distances for extension faculty may be increased and require a high degree of planning and coordination; 2) depending on the housing location of the shared specialist, response time can be greater than if program were housed in-state; and 3) shared programs require open, effective, and increased communications among cooperators. In our experience, the benefits of regionalization far outweigh the additional challenges encountered. However, to be successful: 1) the whole must be greater than the sum of the parts; 2) each partner must have identify preservation; 3) stakeholders must realize value from the programs and must be kept abreast of program successes to assure their continued support.
