In recent years, traditional printing methods have been integrated to print flexible electronic devices and circuits. Since process requirements for electronics diff er from those for graphic printing, the fundamentals require rediscovery mainly to optimize manufacturing techniques and to find cost reduction methods without compromising functional performance. In addition, alternative inks need to be formulated to increase the variety of functional inks and to pioneer new product developments. In this report, we investigate a thermoplastic-based nickel ink prototype to print electrodes using a screen-printing process. Process fundamentals are explored, and cost reduction methods are addressed by studying …

The packaging sector is one of the massive traditional fields in the printing industry. The rapid developments in technology and environmental regulations have been affecting the expectations from packaging. User demands and the concerns to protect the environment are the two main factors that now demanding change in material properties. The choice used to depend on the physical and chemical requirements of the products, although today’s global mind set on the concepts such as biodegradability, recyclability, reusability, sustainability and carbon footprint reduction are becoming the reason to tailor packaging properties. In general, the choices have been switching from petroleum to …


Work In Progress: Institutional Context And The Implementation Of The Redshirt In Engineering Model At Six Universities, Ann Delaney, Donna C. Llewellyn, Janet Callahan Jun 2018

Work In Progress: Institutional Context And The Implementation Of The Redshirt In Engineering Model At Six Universities, Ann Delaney, Donna C. Llewellyn, Janet Callahan

Materials Science and Engineering Faculty Publications and Presentations

Low-income students are underrepresented in engineering and are more likely to struggle in engineering programs. Such students may be academically talented and perform well in high school, but may have relatively weak academic preparation for college compared to students who attended better-resourced schools. Four-year engineering and computer science curricula are designed for students who are calculus-ready, but many students who are eager to become engineers or computer scientists need additional time and support to succeed. The NSF-funded Redshirt in Engineering Consortium was formed in 2016 as a collaborative effort to build on the success of three existing “academic Redshirt” programs …


The Redshirt In Engineering Consortium: Progress And Early Insights, Janet Callahan, Donna C. Llewellyn, Ann E. Delaney Jun 2018

The Redshirt In Engineering Consortium: Progress And Early Insights, Janet Callahan, Donna C. Llewellyn, Ann E. Delaney

Materials Science and Engineering Faculty Publications and Presentations

The NSF-funded Redshirt in Engineering Consortium was formed in 2016 with the goal of enhancing the ability of academically talented but underprepared students coming from lowincome backgrounds to successfully graduate with engineering degrees. The Consortium takes its name from the practice of redshirting in college athletics, with the idea of providing an extra year and support to help promising engineering students complete a bachelor’s degree. The Consortium builds on the success of three existing “academic redshirt” programs and expands the model to three new schools. The Existing Redshirt Institutions (ERIs) help mentor and train the new Student Success Partners (SSPs), …


Encouraging A Growth Mindset In Engineering Students, Megan Frary Jun 2018

Encouraging A Growth Mindset In Engineering Students, Megan Frary

Materials Science and Engineering Faculty Publications and Presentations

A person’s “mindset” guides a great deal of how one approaches life -- and especially how students approach education. While someone with a fixed mindset believes that their intelligence is fixed and unchangeable, someone with a growth mindset believes that their intelligence is changeable and can grow as they learn more. Most people’s mindset lies along a spectrum with these two extremes at either end. In addition to other outcomes, the mindset that a person has determines how they interpret mistakes they make; whereas someone with a fixed mindset thinks mistakes result from their innate lack of ability, someone with …


Next Generation Protocol: Innovating A Resilient Future, Andrew Steven Rudnick, Jamie Cannady, Joe Decesaro, Juan A. Ortiz Salazar Jun 2018

Next Generation Protocol: Innovating A Resilient Future, Andrew Steven Rudnick, Jamie Cannady, Joe Decesaro, Juan A. Ortiz Salazar

Materials Engineering

Conventional practices do not account for product life beyond end-of-sale – these practices are not sustainable. We have developed an end-of-life protocol that includes a metric that we call the Recovery Rating. The objectives of this Next Generation Protocol, beyond supporting the United Nations’ Sustainable Development Goals, are to encourage the production of goods designed for recovery and to promote the collaboration between consumers, the public, and the private sector to recover goods at their end-of-life. The Recovery Rating that we propose evaluates and quantifies recovery potential of products. The Recovery Rating, which is normed against embodied energy from the …

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler Apr 2018

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler

Public Land & Resources Law Review

In Hawai’i Wildlife Fund v. County of Maui, the Ninth Circuit held that the plain language of the Clean Water Act provides jurisdiction over indirect discharges of pollutants from a point source into groundwater that is shown to be connected to navigable waters. The court found that studies confirmed pollutants entering the Pacific Ocean were fairly traceable to the County of Maui’s sewage disposal wells. In affirming the district court’s ruling, the Ninth Circuit held that Maui County violated the Clean Water Act by discharging pollutants into a navigable water without the required permit. The court also concluded the …

Creating A Stem Identity: Investment With Return, Janet Callahan, Patricia Pyke, Susan Shadle, R. Eric Landrum

R. Eric Landrum

Establishing a strong STEM (science, technology, engineering and mathematics) identity at Boise State University, a metropolitan campus with approximately 3,655 undergraduate STEM students and a total undergraduate enrollment of approximately 19,042 (16,136 FTE) has been an important step toward creating a climate conducive to facilitating fundamental change. Examples of such change include building collaborations among faculty within and across departments, establishing the identity of students as part of a community beyond their chosen major, improving the efficiency and effectiveness of university systems, and perhaps most importantly, developing a framework to think deliberately about ways to effect change. This paper is …

A fully printed nickel (Ni) based resistance temperature detector (RTD) was successfully developed for temperature sensing applications in the automobile, agricultural and consumer electronic industries. The RTD was fabricated by
depositing nickel (Ni) ink on a flexible polyimide (PI) substrate using screen printing process. The capability of the printed RTD was demonstrated by measuring its resistive response for temperatures varying from -60 °C to 180 °C, in steps of 20 °C and its sensing characteristics such as linearity, sensitivity and repeatability were analyzed. The printed RTD demonstrated a linear response with resistive changes as high as 109% at 180 °C, …
