Paper in electronic and optoelectronic devices

March 6, 2018
Author(s)
Dongheon Ha, Zhiqiang Fang, Nikolai B. Zhitenev
The demand for lightweight, cost-effective, and/or flexible electronic and optoelectronic devices drives research toward new materials advancing the desired functionality or reducing manufacturing costs. Paper, being in addition an earth abundant and

Blade Coating Aligned, High-Performance, Semiconducting-Polymer Transistors

February 22, 2018
Author(s)
Lee J. Richter, Hyun W. Ro, Regis J. Kline, Daniel A. Fischer, Dean M. DeLongchamp, Lars Thomsen, Christopher McNeil, Dawei Wu, Maria Kaplan, Eliot H. Gann
Recent demonstration of mobilities in excess of 10 cm2V-1s-1 have energized research in solution deposition of polymers for thin film transistor applications. Due to the lamella motif of most soluble, semiconducting polymers, the local mobility is

Structure, Nanomechanics and Dynamics of Dispersed Surfactant-Free Clay Nanocomposite Films

February 22, 2018
Author(s)
Xiao Zhang, Jing Zhao, Chad R. Snyder, Abdullah Al-Enizi, Ahmed Eltazahry, Alamgir Karim
Using additives to tailor the performance of polymeric materials is perhaps one of the most important aspects for producing materials of advanced applications. The exploitation of nanoparticle dispersion strategies have been broadly investigated for tuning

Acid-induced and pH-controlled Reversible Switching of Broad-Spectrum Antibacterial Activity

February 13, 2018
Author(s)
Yin Y. Nelson, Vytautas Reipa, Xiaohong Wang, Kenneth Mineart, Vivek M. Prabhu, Nancy J. Lin, Jirun Sun
Bacterial resistance to antimicrobials is threatening millions of human lives due to indiscriminate overuse and environmental build-up of antibiotics. We present the smart regulation of antibacterial activity in biologically relevant conditions to reduce

A Kinetics Based Models for Environmentally Induced Sealant Degradation

February 12, 2018
Author(s)
Donald L. Hunston, Christopher C. White
Caulks and sealants are a critical part of any structure that is exposed to the environment. Although they are good materials, they eventually fail, and the failure is often difficult to detect before extensive damage is generated by water ingress or loss

Optimizing Self-Consistent Field Theory Block Copolymer Models with X-Ray Metrology

February 12, 2018
Author(s)
Adam F. Hannon, Daniel Sunday, Alec Bowen, Gurdaman Khaira, Jiaxing Ren, Paul Nealey, Juan de Pablo, Regis J. Kline
A block copolymer self-consistent field theory (SCFT) model is used for direct analysis of experimental X-ray scattering data obtained from thin films of polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA) made from directed self-assembly. In a departure

Synchrotron Methods for Flexible Hybrid Electronics Industrial Recommendations on Interagency (DoC-DoD-DoE) Partnerships to Address Measurement Challenges Hindering the Flexible Hybrid Electronics Manufacturing Ecosystem

February 12, 2018
Author(s)
Christopher L. Soles, Richard A. Vaia, Ronald Pindak
The round-table participants concluded that facilities at NSLS-II provide immediate opportunities to address some of the critical processing and measurement challenges that are blocking the path towards a sustainable US-centric Flexible Hybrid Electronic

Differential degradation patterns of photovoltaic backsheets at the array level

February 4, 2018
Author(s)
Andrew W. Fairbrother, Matthew Boyd, Yadong Lyu, Julien Avenet, Peter Illich, Michael Kempe, Brian P. Dougherty, Laura Bruckman, Xiaohong Gu
Photovoltaic backsheet degradation is commonly related to end-of-life failure of a module, and as such is an important factor in system reliability and longevity. Some module manufacturers have recently begun utilizing non-fluoropolymer-based backsheets in

Ferroelectricity in Polar Polymer-based FETs: A Hysteresis Analysis

January 15, 2018
Author(s)
Vasileia Georgiou, Dmitry Veksler, Jason Campbell, Jason Ryan, Pragya Shrestha, D. E. Ioannou, Kin P. Cheung
There is an increasing number of reports on polar polymer-based Ferroelectric Field Effect Transistors (FeFETs), where the hysteresis of the drain current - gate voltage (Id-Vg) curve is investigated as the result of the ferroelectric polarization effect

Nanostructured lipid-based films for substrate-mediated applications in biotechnology

January 10, 2018
Author(s)
Minjee Kang, Mohit Tuteja, Andrea Centrone, Daniel Topgaard, Cecilia Leal
Amphiphilic in nature, lipids spontaneously self-assemble into a range of nanostructures in the presence of water. Among lipid self-assembled structures, liposomes and supported lipid bilayers have long held scientific interest for their main applications

Validation of ATR FT-IR to identify polymers of plastic marine debris, including those ingested by marine organisms

January 3, 2018
Author(s)
Melissa R. Jung, F. D. Horgen, Sara Orski, Viviana Rodriguez Cardenas, Kathryn Beers, George H. Balazs, T. T. Jones, Thierry M. Work, Kayla C. Brignac, Sarah-Jeanne Royer, K. D. Hyrenbach, Brenda A. Jensen, Jennifer Lynch
Polymer identification of plastic marine debris can help identify its sources, degradation, and fate. We optimized and validated a fast, simple, and accessible technique, attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR), to
