Observation of optomechanical buckling phase transitions

March 1, 2017
Author(s)
Jacob M. Taylor, John R. Lawall, Haitan Xu, Utku Kemiktarak, Jingyun Fan, Stephen Ragole
Correlated phases of matter provide long-term stability for systems as diverse as solids, magnets, and potential exotic quantum materials. Mechanical systems, such as relays and buckling transition spring switches can yield similar stability by exploiting

Performing Skin Microbiome Research: A Method to the Madness

March 1, 2017
Author(s)
Heidi H. Kong, Bjorn Andersson, Thomas Clavel, John E. Common, Scott Jackson, Nathanael Olson, Julia Segre, Claudia Traidl-Hoffman
Growing interest in microbial contributions to human health and disease has increasingly led investigators to examine the microbiome in both healthy skin and cutaneous disorders, including acne, psoriasis, and atopic dermatitis. The need for common

Reference nanomaterials to improve the reliability of nanoscale measurements

March 1, 2017
Author(s)
Gert Roebben, Vincent A. Hackley, Hendrik Emons
Reference materials are essential tools to assure the quality of measurement results, from R&D labs to production facilities. They help increase the reliability of measurements, as laboratories can use reference materials to verify, for themselves, and

Standardizing CT Lung Density Measure Across Scanner Manufacturers

March 1, 2017
Author(s)
Huaiyu H. Chen-Mayer, Matthew Fuld, Bernice Hoppel, Phillip Judy, Junfeng Guo, David Lynch, Antonio M. Possolo, Sean B. Fain
Computed Tomography imaging of the lung, reported in Hounsfield Units (HU), can be parameterized as a quantitative image biomarker for the diagnosis and monitoring of lung density changes due to emphysema, a type of chronic obstructive pulmonary disease

A Classification Scheme for Smart Manufacturing Systems Performance Metrics

February 28, 2017
Author(s)
Yung-Tsun T. Lee, Senthilkumaran Kumaraguru, Sanjay jain, Qais Hatim, Stefanie Robinson, Moneer M. Helu, Sudarsan Rachuri, Soundar Kumara, Christopher Saldana, David Dornfeld
This paper proposes a classification framework for performance metrics for smart manufacturing systems. The discussion focuses on agility, asset utilization, and sustainability, and we discuss classification themes for each of these areas that lead to the

Metal Additive Manufacturing Standardization in Support of Qualification and Certification

February 28, 2017
Author(s)
Mohsen Seifi, Michael Gorelik, Jess Waller, Nik Hrabe, Nima Shamsaei, Steve Daniewicz, John J. Lewandowski
As the metal Additive Manufacturing (AM) industry moves towards industrial production, the need for qualification standards covering all aspects of the technology becomes ever more prevalent. While some standards and specifications for documenting the

Biological Uptake, Distribution and Depuration of Radio-labeled Graphene in Adult Zebrafish: Effects of Graphene Size and Natural Organic Matter

February 27, 2017
Author(s)
Kun Lu, Shipeng Dong, Elijah Petersen, Xiaofeng Chang, Peng Wang, Sijie Lin, Liang Mao
The exciting commercial application potential of graphene materials may inevitably lead to their increasing environmental exposure and risk. This study focused on using carbon-14 labeled few-layer graphene (FLG) to determine whether the size of graphene
