Dissolvable tattoo electronics for biomedicine
Wednesday, September 18, 2019;
15:35 - 16:25
114 EES Building
Speaker: Huanyu Cheng from Penn State University
ABSTRACT: Recent advances in electronics enable powerful biomedical devices that have greatly reduced therapeutic risks by monitoring vital signals and providing means of treatment.Implantable devices can help us better understand the behavior and effects of various diseases.However, an additional procedure is required to remove the device after an initial implantation.Conventional electronics today form on the planar surfaces of brittle wafer substrates and are not compatible with the complex topology of body tissues. Therefore, stretchable and absorbable electronics are the two missing links in the design process of implantable monitors and in-vivo therapeutics. This talk presents the challenges, mechanics, and design strategies,behind a potential medical device that (a) integrates with human physiology,and (b)dissolves completely after its effective operation.
Biography:Dr. Huanyu Cheng was appointed an Assistant Professor of Engineering Science and Mechanics (ESM) and Materials Research Institute (MRI) at The Pennsylvania State University in Aug 2015, and was awarded the Dorothy Quiggle Career Development Professor in Sep 2015. He earned a Ph.D. and a Master’s degree from Northwestern University in 2015 and 2011 respectively, and a Bachelor’s degree from Tsinghua University (China) in 2010. Prior to joining Penn State, Dr. Cheng also worked as a Visiting Research Fellow with Prof. John A. Rogers at the University of Illinois at Urbana-Champaign on stretchable and transient electronics. Throughout Dr. Cheng’s research career, he has worked on mechanics design and manufacturing of biologically inspired electronics with applications in robotics, biomedicine, and energy. Dr. Cheng has co-authored over 70 peer-reviewed publications, and his work has been recognized through the reception ofawards including Forbes 30 Under 302017 in Science, election to the Global Young Academy in 2016, a Howard Hughes Medical Institute (HHMI) International Student Research Fellowship, and many others.He also serves as associate editor for Computers in Biology and Medicine and reviewer for 88 international journals.

Air Products Distinguished Lecture Series: "Mechanics-guided Deterministic 3D Assembly"
Tuesday, September 17, 2019;
4:35 PM
162 Willard Building
Speaker: Dr. Yonggang Huang from Northwestern University
Complex three-dimensional (3D) structures in biology form naturally to provide essential functions in even the most basic forms of life. Compelling opportunities exist for analogous 3D architectures in human-made devices, but design options are constrained by existing capabilities in materials growth and assembly. We report routes to previously inaccessible classes of 3D constructs in advanced materials, including device-grade silicon. The schemes involve geometric transformation of 2D micro/nanostructures into extended 3D layouts by compressive buckling. Demonstrations include experimental and theoretical studies of more than 100 representative geometries, from single and multiple helices, toroids, and conical spirals to structures that resemble spherical baskets, cars, houses, cuboid cages, starbursts, flowers, scaffolds, each with single- and/or multiple-level configurations. Morphable 3D mesostructures whose geometries can be elastically altered can be further achieved via nonlinear mechanical buckling, by deforming the elastomer platforms in different time sequences. Compatibility with the well-established technologies available in semiconductor industries suggests a broad range of application opportunities.

The Known Unknowns of Diversity and Inclusion: Supporting Individuals with Hidden and Transitioning Identities
Wednesday, September 18, 2019;
12:00 PM
202 Hammond (Stavely Conference Room)
Speaker: Dr. Stephen Seccules and Cassandra McCall from Virginia Tech
The Leonhard Center is excited to welcome Drs. Stephen Seccules and Cassandra McCall as facilitators for our September workshop, to be held on Wednesday, September 18! Within engineering classrooms, we often think of student diversity as represented by visible or apparent markers such as race and gender. However, students also hold hidden or non-apparent identity dimensions (e.g., sexual orientation, disability, socio-economic status, etc.) that can significantly impact their day-to-day academic experiences. While both visible and hidden identities constitute student diversity, hidden identities are often unknown or go unnoticed by instructors and peers, particularly if a student does not feel safe enough to disclose. In this interactive workshop, we address these known unknowns of diversity by discussing the significance of hidden identities within students' classroom experiences. Specifically, participants will reflect on their own classroom contexts and identify challenges and solutions to make these environments more inclusive and accessible for all students.

Explainable Humans: Algorithmic Decision-Making and Education Policy
Friday, September 27, 2019;
2:00 p.m.
The Cybertorium (W201 Westgate)
Speaker: Elijah Mayfield from Carnegie Mellon University
Abstract:
The high stakes of automated decision-making has produced a need for explainable, equitable machine learning. This talk will explore what it means to give satisfactory explanations for algorithmic judgment calls, and where those explanations come from, with a special focus on natural language processing problems in topics relevant to educators and schools. We focus on two domains, investigating how group debates shape the content deemed notable for inclusion in Wikipedia, and how automated essay scoring learns standards of quality writing from human assessment and rubrics, and how machine learning algorithms encode existing biases in both domains into predictive models.
Biography: Elijah Mayfield is an Entrepreneur-in-Residence at Carnegie Mellon University and Lecturer at the University of Pennsylvania. Previously, he was Vice President of New Technologies at Turnitin, managing machine learning and NLP research for educational products used by over 30 million students globally. He joined Turnitin when they acquired LightSide Labs, which he founded as CEO with support from the Gates Foundation, the US Department of Education, and others. Mayfield has coauthored more than 40 peer-reviewed publications on language technologies and human-computer interaction, receiving awards including a Siebel Scholarship, an IBM Ph.D. Fellowship, and Forbes 30 under 30 in Education.

Bridging the Gap Between What Students Know about General Writing and What Is Expected in Engineering Writing
Thursday, October 3, 2019;
12:00 PM
202 Hammond (Stavely Conference Room)
Speaker: Michael Alley from The Pennsylvania State University
Because most engineering students at Penn State do not take technical writing until their junior or senior year, a gap exists between what the students have learned in general writing courses, such as freshman composition, and what we expect them to know when they write a design report or laboratory report. This workshop facilitated by Michael Alley presents a 1-hour class period that you can incorporate into your course that tries to bridge that gap. Using teaching materials developed by the Leonhard Center, this class period has the following three goals: persuade engineering students that their writing as an engineer is important; dispel common misconceptions that students hold about engineering writing; and help students prepare an effective outline for their next writing assignment. A centerpiece of the class period is a website (www.craftofscientificwriting.com/summary.html) that serves as a preparation assignment for the students. Lunch will be served

3D Printing, porosity, synchrotron experiments and machine learning
Wednesday, October 9, 2019;
15:35 - 16:25
114 EES Building
Speaker: Anthony Rollett from Carnegie Mellon University
3D printing of metals has advanced rapidly in the past decade and is used across a wide range of industry. Many aspects of the technology are considered to be well understood in the sense that machines make parts and temperature histories with residual stress can be simulated. At the microscopic scale, however, more work is required to quantify, understand and predict defect-and micro-structures, which affect properties such as fatigue resistance. The most dramatic synchrotron-based technique is dynamic x-ray radiography (DXR) which provides ultra-high speed imaging of laser melting of metals and their powders. This has, e.g., enabled the keyhole phenomenon to be quantified, which in turn has demonstrated the importance of power density, as opposed to energy density. This latter quantity, while informative, also fails to capture the crucial boundary between full density and lack-of fusion porosity because it does not take account of melt pool overlap. Synchrotron-based 3D X-ray computed microtomography (µXCT) showed that essentially all metal powders exhibit porosity that partially persists into the printed metal. This explanation is reinforced by evidence both DXR and simulation. To illustrate the power of machine learning, Computer vision (CV) has successfully classified different microstructures, including powders. The power of CV is further demonstrated by its ability to detect and classify defects in the spreading of powder. High speed synchrotron x-ray diffraction is beginning to provide new information on solidification and phase transformation in, e.g., IN718, Ti-6Al-4Vand stainless steel. High Energy (x-ray) Diffraction Microscopy (HEDM) experiments also is also providing data on 3D microstructure and local elastic strain in 3D printed materials such as Ti-6Al-4Vand stainless steel.
