Materials Discovery by Crystal Growth
Authors: Mugavero III Samuel J. , Gemmill William R , zur Loye Hans-Conrad 
Published: June 2019

AbstractThe growth of new phases out of high temperature hydroxide solutions as a means of discovering new materials is discussed. We have succeeded in solubilizing rare earth cations and platinum group metal cations in molten hydroxides and have grown single crystals with a large number of new compositions and new structure types. The use of sealed silver tubes has enabled us to control the water content and, hence, the acidity of the hydroxide melts, and thereby to grow crystals via slow cooling. The synthetic conditions and structures of several new oxides including Ln1-xNa1+xIrO4 (Ln = Gd-Er, Y; x = 0.04-0.26), Ln3RuO7 (Ln = La, Sm, Eu), LnNaPd6O8 (Ln = Tb-Lu, Y) and La9RbIr4O24 are presented.

AbstractWe demonstrate monochromatic and white light optical amplification of the photo-oxidation of adsorbed methylene blue using an inverse colloidal photonic crystal fashioned from anatase nanocrystals, denoted i-nc-TiO2-o. Enhanced photo-activity that drives the oxidation of the dye is attributed to slow photons in i-nc-TiO2-o. When the slow photon wavelength is optimized with respect to the electronic excitation energy of i-nc-TiO2-o, the photo-oxidation rate of the dye is doubled compared to conventional nc-TiO2. By increasing the probability of absorbing photons in i-nc-TiO2-o relative to nc-TiO2, a larger population of electron-hole pairs is generated enabling more efficient photo-oxidation. Slow photons in photonic crystals portend a myriad of opportunities for amplified photo-processes in chemistry and biology.
Computer Modeling of Nanoporous Materials: An ab initio Novel Approach for Silicon and Carbon
Authors: Valladares Ariel A. , Valladares Alexander , Valladares R. M. 
Published: June 2019

AbstractCarbon and silicon have been consistently proposed as elements useful in the generation of porous materials. Carbon has been insistently postulated as a promising material to store hydrogen, and crystalline silicogermanate zeolites have recently been synthesized and are being considered in catalytic processes. In the present work we report an approach to generating porous materials, in particular porous carbon and silicon, which leads to the existence of nanopores within the bulk. The method consists in constructing a crystalline diamond-like supercell with 216 atoms with a density (volume) close to the real value, then halving the density by doubling the volume (50% porosity), and subjecting the resulting supercell to an ab initio molecular dynamics process at 300 K for Si, and 1000 K for carbon, followed by geometry relaxation. The resulting samples are essentially amorphous and display pores along some of the “crystallographic” directions. We report their radial distribution functions and the pore structure where prominent.
Feedback Loops Along The Pre-Requisite Tree

Published: June 2019

ABSTRACTThe ABET Engineering Criteria 2000 is stimulating development of quantitative feedback systems in the context of Engineering education. Efforts in developing feedback loops that carry quantitative information to facilitate the improvement of student learning in several engineering majors is summarized. Feedback loops are designed around the course learning objectives that were developed in the context of professional criteria specified by professional societies as well as ABET EC 2000 criteria 2 and 3, which define capabilities that all engineers must gain. Two feedback structures are described – one brings information from external sources such as alumni, employers, and the external advisory board, while the other moves information up and down the pedagogical prerequisite tree. Both loops go through the ABET/curriculum committee for assessment of progress and identification of needed changes. The tool developed to facilitate communication up and down the prerequisite tree is the course evaluation form, on which student and faculty assess students' mastery of the learning objectives. This form is passed through feedback loops that operate on many scales. Progress toward implementation is described, with emphasis on service courses that see student flow between different departments.

ABSTRACTA variety of educational resources are available in the area of materials science and engineering. These resources are widely dispersed and are often hard to find. Several efforts to collect and categorize the wide variety of educational modules, demonstrations, laboratories and texts have been launched in recent years, but none have been able to incorporate the vast majority of resources. The current effort is funded by NSF and has been collecting information from a variety of sources over the past year. It is being integrated with the Materials Education Library project that has been under way at the University of Michigan since 1997. These projects will result in a fully searchable database, published both on the world wide web and in a print catalog, with the first edition being available by summer 2000. The draft web site may be found at http://msewww.engin.umich.edu/MEL/; a permanent web site will be available by the end of 2000.
A New Role for Engineering Educators: Managing for Team Success
Authors: Larson Debra S. 
Published: June 2019

ABSTRACTFor a variety of reasons, collaborative learning teams, project teams or design teams are now a part of undergraduate engineering education. In response, the current education-related literature is flourishing with team-type topics that include when and why teams, team dynamics, and how to structure teams. Almost non-existent, however, are discussions about the role and impact of the faculty member in and on student teams.Extrapolating from the professional project management literature, project and team success is heavily influenced by positive management. Businesses that fail to train and reinforce positive management run unacceptable risks. The risks to us as educators, who use teams in less than ideal situations, include a lack of learning, project failure, and dysfunctional teams that foster an aversion to teams. This is in direct contrast to what we hoped and what we have been asked to do, which is to provide an understanding about the power of teams, to develop teaming skills, to enable design successes, and to enhance the learning.Proper management of student teams requires skills and strategies that are much different from those that most faculty members are experienced with. The strategies include planning for and implementing an understood work process, providing a suitable organization compatible to that process, structuring and communicating with the team, and holding the individual accountable. The skills start with two risk taking beliefs: (1) you do not have to have all the answers and (2) it is not you against them, but about you with them. With the right attitude, the skills of leading by example, guiding towards peak performance, and managing for optimal team experiences follow.
Further Study of the Effect of Group Size on Student Performance
Authors: Sutko A. A. 
Published: June 2019

ABSTRACTIn a 1992 issue of the International Journal of Engineering Education, this author reported on the effects of laboratory group size on student performance. Most of the information was obtained from a material science laboratory. The data indicate that individuals in groups of two or four students tended to receive better final course grades than those from groups of three. Discussion was given concerning the possible reasons for this finding along with information from the then current literature. This paper includes the key components of the 1992 paper and updates it with data obtained since then. It also includes information from other literature published in the recent past. The conclusions reached in the 1992 paper appear to remain valid.
Feeding the Recruitment of Inner City Kids to MSE by Keeping 5TH Graders on Track for Engineering in College
Authors: Brower William E. 
Published: June 2019

ABSTRACTThe fifth grade inner city volunteer teaching project (5GVP) at Marquette University's College of Engineering has attempted to inform and inspire Milwaukee's inner city fifth graders about engineering for the last ten years. Each year I have recruited our engineering students to volunteer to take self contained science lessons into the Milwaukee Public Schools'fifth grade classrooms. Although the lessons are on science and the career touted is engineering in general, the lessons are flavored by my being in MSE. Being excited about a career is certainly a precursor to choosing that career. I have found the fifth graders very excited about seeing and experiencing science in action as the engineering students present it to them. Hopefully, the program at Marquette will result in more inner city students choosing to enter college as engineers, with MSE garnering its usual share.

ABSTRACTThe online educational module “Why Does a Light Bulb Burn Out?” is an inquiry-based introduction to the concepts of materials and material properties through the interactive exploration of the life of the incandescent light bulb that students use every day. The module offers an exploration of the history of the light bulb, its components, and important filament properties. Students discover the relationship between temperature and incandescence, along with electrical power and resistance through interactive Java applets. Then students “invent” their own filaments through virtual temperature, performance and longevity tests of a variety of candidate materials. Next, students follow the filament aging process using scanning-electron/atomic-force microscopy images. The module culminates in students designing their own materials experiments using SPM Live! online at http://invsee.asu.edu. Student evaluations indicate students both enjoy and learn effectively using the module.
“Collective Undergraduate Research: A Teaching / Learning Tool For MSE Students”
Authors: Wahby Wafeek Samuel 
Published: June 2019

ABSTRACTA new experiment to implement and collectively publish undergraduate students' research was started at the School of Technology, Eastern Illinois University in the Fall of 1998. A summary of the procedures followed in this experiment, its assessment and its progress are presented. Collective research publications, authored by undergraduate engineering students and edited by their faculty can be used as an effective teaching / learning tool that benefits students/authors, their peers, faculty/editors, local and other institutions, and industry at large, particularly when this research is interactively posted on the Internet. Through a research study format, undergraduates learn the subject matter much better, become familiar with research methods and techniques early in their careers, and polish their technical writing abilities. As the experiment also fosters teamwork and peer collaboration and evaluation, undergraduates sharpen their oral communication skills through group discussions and in-class presentations. The experiment provided an opportunity for students to independently select and research a particular topic and helped them discover the research resources and reference materials available on the subject matter. As one of the few creative opportunities offered in a class, this experiment presented a variety of learning environments to undergraduates and helped promote their creativity and self-directed learning. It was confirmed that most undergraduate students hold unlimited potential for success as researchers, and that enthusiasm, hard work, self-motivation, and dedication of students are likely to constitute better indicators of success than the conventional grades they earned in the past.

Digital Ties, Disrupted Togetherness: Locating Uneven Communicative Mobilities in Transnational Family Life
Authors: Cabalquinto Earvin Charles 
Published: June 2019

Ubiquitous digital communication technologies play a crucial role in shaping the nature of family life at a distance. Paradoxically, mobile device use has not only brought dispersed family members together, it also sometimes stirs communicative tensions in transnational households. These tensions are often produced by uneven access to a wide range of re-sources in mediated communication. Employing the mobilities lens, this paper examines the role of smartphones and networked communications platforms in binding ties and relationships among twenty-one overseas Filipino workers in Melbourne, Australia, and their left-behind family members in the Philippines. Based on data drawn from in-depth interviews and photo elicitation, the research study uncovers the performance, embodiment, and negotiation of transnational relationships through mobile device use. Signifcantly, it also demonstrates the impact of structural and infrastructural forces in enabling differential mediated mobilities. In illuminating asymmetrical mobile communication, I propose six categories: access, socio-technical competency, quality of connectivity, rhythms, affective experience, and communicative space. Ultimately, this paper offers a critical lens on investigating mobile practices in the conduct of transnational family life.
Digital Family Ethnography: Lessons from Fieldwork in Australia
Authors: Winarnita Monika 
Published: June 2019

This article discusses the opportunities and constraints in using a digital family ethnography for qualitative studies amongst Indonesians in Australia. The frst half of the article highlights the opportunities that online and offine participant observation can provide in terms of understanding family transnational networks. Going beyond an ego-based narrative approach in interviews, digital family ethnography shows how social network analysis and refexivity can bring depth to a study on family by including the researcher’s position vis-à-vis the research participants. The second half of the article discusses challenges in using these combined online and offine methods and how these challenges might be mitigated in future studies. In particular, the article look at problems faced with interviews, multimedia usage, and social media analysis related to the researcher’s background and in working with different age groups. In the transnational family context, social media and electronic communication are critical parts of contemporary ethnographic methodologies, and the discussion thus centres on including online personhood in the research. The study concludes that although digital family ethnography methodologies have limitations, they can be used to account for the transforming relationships that make up family mobility.
