Bubble And Pattern Formation In Liquid Induced By An Electron Beam, Joseph M. Grogan, Nicholas M. Schneider, Frances M. Ross, Haim H. Bau Dec 2013

Bubble And Pattern Formation In Liquid Induced By An Electron Beam, Joseph M. Grogan, Nicholas M. Schneider, Frances M. Ross, Haim H. Bau

Departmental Papers (MEAM)

Liquid cell electron microscopy has emerged as a powerful technique for in situ studies of nanoscale processes in liquids. An accurate understanding of the interactions between the electron beam and the liquid medium is essential to account for, suppress, and exploit beam effects. We quantify the interactions of high energy electrons with water, finding that radiolysis plays an important role, while heating is typically insignificant. For typical imaging conditions, we find that radiolysis products such as hydrogen and hydrated electrons achieve equilibrium concentrations within seconds. At sufficiently high dose-rate, the gaseous products form bubbles. We image bubble nucleation, growth, and ...

The engineering student experience is understood to differ for male and female students; gendered interactions affect the development of academic and professional role confidence, as well as engineering identity. The purpose of this session is twofold. First, we aim to introduce participants to concepts of gender schemas, privilege, and identity using a range of interactive activities, including brainstorming and structured discussion. Second, we intend to share information about and obtain feedback on a Gender Discussion Exploration Kit, which the participants will be encouraged to review, use, and share at their home institutions.

Stemsat: An Iss Cubesat Program Based On Spare Parts, Anders Nervold, Josh Berk, Jeremy Straub

Jeremy Straub

With the national government’s focus on driving STEM-education, it is important to provide hands-on ave-nues where students can engage with, and accumulate ex-perience working directly with projects within their fields of interest. The Student Technology Emersion Satellite (STEMSat), provides an avenue for students to become in-volved in CubeSat design and development with only mi-nor hardware and monetary resources, and without being dependent on a launch.

STEMSats are CubeSat satellites that are created from spare parts, residual tools and equipment, obsolete mate-rials, and other types of trash aboard the ISS. A list of all the excess items available for such ...

90° To 360°, Holly Paronelli

The STEAM Journal

When I hear STEM (Science, Technology, Engineering and Mathematics) and Art I think of Math and value. Even though there is value in STEAM (Science, Technology, Engineering, Art and Mathematics) the value as a whole cannot be fully calculated. Art is too indefinite, to vast, too infinite to be calculated, but aspects of STEM can be. Yet even then what we think we know comes down to interpretation, fact is fact for only a while.


Towards A “Cloud Curriculum” In Art And Science?, Roger Malina Mar 2013

Towards A “Cloud Curriculum” In Art And Science?, Roger Malina

The STEAM Journal

Recently an email hit my desk from Paul Thomas in Australia with a proposal to work together on a “Cloud Curriculum for Art and Science”. I immediately agreed to collaborate. I don’t yet have a clue of what a cloud curriculum is, but what I do know is that we are ‘backing into the future’ in educational institutions and we desperately need a ‘cloud curriculum.’ We need to look over the ten year horizon. And in the emerging art-science field I doubt that the usual approach to curriculum development will work.

Getting Real About The E In Steam, James Catterall Mar 2013

Getting Real About The E In Steam, James Catterall

The STEAM Journal

STEM and STEAM are in the news. Researchers and educators in my field (cognition, art, and creativity) argue reasons for adding the A to STEM. While I visit this below, my focus is elsewhere. In this brief essay, I want to explore the meaning and importance of the E appearing in both STEM and STEAM. What’s engineering doing in this mix? And what are some reasons for affirming the arts when the role of engineering is clarified?

Academic And Social Barriers To Black And Latino Male Collegians' Success In Engineering And Related Stem Fields, Terrell Lamont Strayhorn, Leroy L. Long Iii, Joseph Allen Kitchen, Michael Steven Williams, Meg E. Stenz

Publications

Historically underrepresented racial/ethnic minorities (i.e. African Americans, Latinos, and Native Americans) have experienced barriers to their success in engineering and related STEM fields. These student populations have had lower degree attainment rates, switch to non-STEM majors more frequently, and experience unique social challenges when compared to White and Asian Pacific Islander counterparts. To examine these findings, nearly 50 interviews were conducted and analyzed in the present study to better understand the academic and social experiences of African American and Latino American men in these fields. Interviews revealed that these students tend to (1) feel alone and invisible, (2 ...

Simultaneous Bright-Field And Dark-Field Scanning Transmission Electron Microscopy In Scanning Electron Microscopy: A New Approach For Analyzing Polymer System Morphology, Binay Surendra Patel

Theses and Dissertations

Scanning transmission electron microscopy in scanning electron microscopy (STEM-IN-SEM) is a convenient technique for polymer characterization. Utilizing the lower accelerating voltages, larger field of view and, exclusion of post-specimen projection lens in an SEM; STEM-IN-SEM has shown results comparable to transmission electron microscopy (TEM) observation of polymer morphology. Various specimen-holder geometries and detector arrangements have been used for bright field (BF) STEM-IN-SEM imaging. To further the characterization potential of STEM-IN-SEM a new specimen holder has been developed to facilitate simultaneous BF and dark field (DF) STEM-IN-SEM imaging. A new specimen holder and a new microscope configuration were designed for this ...

The shortage of women in science, technology, engineering, and mathematics (STEM) is well-documented.
Many efforts address women’s low representation in fields such as computing target high
school girls in an effort to solidify their commitment to these fields before they enter college and create
computing “potential selves.” This paper describes one such effort in the rural South, the Women in
Cyber Security residential camp for girls in Mississippi. Consistent with existing literature, we find
girls are interested in the social relevance of various technological skills and desire hands-on, applied
learning exercises. We also find girls are poorly informed about ...
