Method Development for Carbon Analysis With TXRF
It is important that carbon used for energy storage applications be high purity. Metals and other impurities can cause degradation of device components, shortening lifetime. Granular carbon samples currently are prepared by hand milling which cannot produce the recommended particle size. To adhere to testing standards, a BeadRuptor was introduced to lower the particle size and reduce user variability in preparation methods of high purity carbon samples.

RAIN Geology Project
Currently, there seems to be an obsession with STEM studies among students. This "trend" makes it easy to overlook the students with an economic disadvantage that surpasses their passion. Our project aims to confront this issue by bringing a scanning electron microscope into mainly low-income classrooms via remote access, a free tool with low publicity. We administered a multidisciplinary lab and validated student findings with the SEM in order to figure out whether access to the SEM influences students' interest in Science. Via qualitative responses, we found that indeed, the SEM did heighten their interests in the study of Science.

Microsystem Photolithography Process Characterization
Photolithography is one of the most critical process steps in microsystem device manufacturing. There are dozens of variables that contribute to overall quality and yield. This poster will provide results of clean room process characterization experiments done as part of an advanced manufacturing technician course.

The Effects of Hyperbaric Oxygen on Cellular Metabolism
Lack of sufficient blood flow and vascularization is an obstacle for in-vitro tissue engineering. Hyperbaric oxygen utilizes increased pressure and concentration of oxygen, and has shown evidence for increased growth rate and differentiation with in-vitro tissue cultures. Increasing oxygen concentration may provide a direct growth stimulus, while providing adequate oxygen to cell cultures in media and in tissue scaffolding. In this study, Saccharomyces cerevisiae is used to research the effects hyperbaric oxygen has on simple cellular metabolism with the use of spectroscopy, a confocal microscope, and resazurin reagent dye.

Assessing the Electrochemical Response of Microcontact-Printed Silver Nanogrids Utilizing Cyclic Voltammetry
This work involves elucidating the electrochemical behavior of silver nanogrids formed using microcontact-printed templates. Cyclic voltammetry is used to examine the electroanalytical response of the silver nanogrid electrode in the presence of a hexamine ruthenium (III) chloride (Ru(NH3)6Cl3) redox probe. Scanning electron microscopy is used to assess the morphology of the silver nanowire electrodes, and atomic force microscopy is used to determine nanogrid dimensions. The motivation behind this experiment is to determine if voltammograms obtained from silver nanogrids resemble the characteristic sigmoidal shape observed with commercially available ultramicroelectrodes (UMEs). If so, this suggests that hemispherical diffusion is the primary means of mass transport between the bulk solution and the silver nanogrid.

Microsystems Thin Film and Etch Processes and Characterization
This presentation will provide a look inside the various processes of creating thin films and etching procedures on Silicon. Sample wafers will be displayed.

Expanding Technical Education Opportunities through Distance Learning in Telepresence Classrooms
Resource-sharing between higher ed institutions can potentially provide student-learning opportunities that transcend geographic barriers. As part of Project ReVAMP (NSF DUE #1400408), Normandale Community College established collaborative distance learning opportunities with industry partners and colleges to deliver vacuum technology courses in a telepresence classroom. Vacuum technicians fill a critical role in advanced manufacturing industries. Distance learning partnerships provide students with access to education opportunities that may not be locally available. And these partnerships help sustain the vacuum technology program at Normandale. This presentation will explore the workflows and policies that support partnerships and sustainability.

Robust Educational Pathways for Manufacturing at all Scales
Let’s leverage MNT and other workforce resources for manufacturing at all scales from macro to Nano. We have addressed workforce needs across diverse 50+ small-medium-large high-tech businesses over last six years, through partnerships whereby even the first year students are able to start working after completion of required co-op while taking hybrid classes on evenings and Saturdays. Our adaptable framework is poised to address emerging workforce needs of MEMS and Photonics industries across NY State. Together, we can help fill current and future hard-to-fill jobs across the nation in urban, semirural and rural communities, and generate economic impact of $1M/decade/technologist.

Development of MEMS Course Content Using LabView and Arduino
The use of sensors such as accelerometers, gyroscopes, and pressure sensors in systems today is widespread. Electronic circuits are used to capture and transform sensor outputs, but currently we do not focus much on teaching this technology because it is perceived as too advanced. Three new MEMS courses introduce the use of sensors with design and testing of electronic circuits that include the use of LabView and Arduino microcontrollers and should provide a “home” for teaching this technology within an engineering technology program.

Learning though Visualization at the Nanoscale
Visualization at the nanoscale coupled with measurement enhances the students’ understanding of the material down to smallest levels of matter where intuition and textbook examples alone are not enough. This also allows instructors to improve teaching effectiveness by relating to the abstract concepts of nanoscale phenomena with real-time visualization. Most of the instruments used to visualize and measure at the nanoscale are difficult to operate and not affordable for small educational institutions. The purpose of our presentation is to discuss the use of remotely accessible instruments which allow students to control a range of visualization and characterizing instruments over the Internet in real time from their classrooms across the country. These mostly free facilities are an excellent source of learning for students and Instructors especially at the educational institutions that are starting new courses or programs in nanotechnology. Benefits and applications of visualization in real life will also be discussed.

Teaching Ethical and Social Implications of Nanotechnology in a STS course
The implications of nanotechnology encompass so many areas such as ethics, privacy, environment, and security. This presentation will cover methodologies used to teach ethical and social implications of nanotechnology in a Technology, Society, and Society (STS) course. There are four objectives for course: (1) developing a strong understanding of local/global forces which affect societies, (2) guiding societies to appropriate use of technology, (3) alerting societies to technological risks and failures, and (4) developing informed decision-making and leadership. It is anticipated that that by teaching about the ethical and social implications of nanotechnology, educators can further promote high-order thinking in students.

Outreach through School Counselors
This presentation discusses how NEATEC is utilizing relationships with school counselors to determine the most effective means of generating student interest in career pathways in nanotechnology.

Scanning Electron Microscope Course as Part of Nanotechnology Education
This talk summarizes the success and lessons learned from using a Scanning Electron Microscope (SEM) as part of nanotechnology education. Clarion University is a teaching university located in North Western Pennsylvania. It is approximately two hours drive away from any major cities and academic centers. Clarion University students and Clarion community members have limited opportunities to have hand-on experience with high technology education. As an attempt to change this situation, a VEGA-3 XMU Scanning Electron Microscope (SEM) from TESCAN was introduced. This research-grade instrument was used in a dedicated SEM course, part of nanotechnology course, undergraduate research, service to local high school students and home-school students, and in the community outreach to the general public.
