Mechanical characterization of sequentially layered photo-clickable thiol-ene hydrogels

September 8, 2016
Author(s)
Aaron Aziz, Joseph Wahlquist, Aaron Sollner, Virginia L. Ferguson, Frank W. DelRio, Stephanie Bryant
Multi-layer hydrogels formed from crosslinked poly(ethylene glycol) (PEG) have shown promise for applications in tissue engineering ranging from vasculature to musculoskeletal tissues. The objective of this work was to characterize the interface resulting

Defense Mechanisms and Nutrient Displacement in Arabidopsis thaliana upon Exposure to CeO2 and In2O3 Nanoparticles

September 1, 2016
Author(s)
Bryant C. Nelson, Sanem Hosbas Coskun, Chuanxin Ma, Hong Li, Huiyuan Guo, Craig Musante, Jason C. White, Baoshan Xing, Om P. Dhankher
Metal-based nanoparticles (NPs) can cause toxicity to terrestrial plants, however there is little understanding of plant defense mechanisms that may counteract nanotoxicity. In the present study, we investigated the defense mechanisms of Arabidopsis

Emerging Metrology for High Throughput Nanomaterial Genotoxicology

August 26, 2016
Author(s)
Bryant C. Nelson, Christa W. Wright, Yuko Ibuki, Maria Moreno-Villanueva, Hanna L. Karlsson, Giel Hendriks, Christopher M. Sims, Neenu Singh, Shareen H. Doak
The rapid development of the engineered nanomaterial (ENM) manufacturing industry has accelerated the incorporation of ENMs into a wide variety of consumer products across the globe. Unintentionally or not, some of these ENMs may be introduced into the

Photochemical transformations of thiolated polyethylene glycol coatings on gold nanoparticles

August 16, 2016
Author(s)
Stacey M. Louie, Justin M. Gorham, Eric A. McGivney, Jingyu Liu, Kelvin B. Gregory, Vincent A. Hackley
Photochemical reactions can result in significant transformations of manufactured nanomaterials in sunlit environments. While transformations of inorganic nanoparticles (NPs) have been investigated extensively, much less attention has been focused on the

Design, sensitivity analysis, and testing of a Caenorhabditis elegans nanoecotoxicity assay

August 11, 2016
Author(s)
Shannon Hanna, Gregory A. Cooksey, Bryant C. Nelson, John T. Elliott, Elijah J. Petersen
Increasing production and usage of engineered nanomaterials (ENMs) has generated widespread interest in measuring their environmental and human health effects. However, the lack of standardized methods for these measurements has often led to contradictory

An Antimony Selenide Molecular Ink for Flexible Broadband Photodetectors

August 3, 2016
Author(s)
Ratan K. Debnath, MD R. Hasan, Arunima Singh, Vladimir P. Oleshko, Shiqi Guo, Asha Rani, Abhishek Motayed, Nhan V. Nguyen, Albert Davydov
The need for low-cost high-performance broadband photon detection with sensitivity in the near infrared (NIR) has driven interest in new materials that combine high absorption with traditional electronic infrastructure (CMOS) compatibility. Here, we

Cryogenic Etching of High Aspect Ratio 400 nm Pitch Silicon Gratings

July 29, 2016
Author(s)
Houxun Miao, Lei Chen, Mona Mirzaeimoghri, Richard Kasica, Han Wen
The cryogenic process and Bosch process are two widely used processes for reactive ion etching of high aspect ratio silicon structures. This paper focuses on the cryogenic deep etching of 400.0 nm pitch silicon gratings. By creating a metal hard mask on
