Author(s)
G. Sala, M. Mourigal, C. Boone, Nicholas Butch, A. Christianson, O. Delaire, A. J. DeSantis, C. L. Hart, R. Hermann, T. Huegle, D. N. Kent, J. Y. Lin, M. Lumsden, M. Manley, D. G. Quirinale, M. B. Stone, Y. Z.
CHESS is a planned direct geometry neutron chopper spectrometer designed to detect and analyze weak signals intrinsic to small cross-sections (e.g., small mass...

Communicating Confidence of Per- and Polyfluoroalkyl Substance (PFAS) Identification via High Resolution Mass Spectrometry

Author(s)
Joseph Charbonnet, Carrie McDonough, Feng Xiao, Trever Schwichtenberg, Dunping Cao, Sarit Kaserzon, Kevin Thomas, Pradeep Dewapriya, Benjamin Place, Emma Schymanski, Jennifer Field, Damian Helbling, Christopher Higgins
Per- and polyfluoroalkyl substances (PFASs) are important environmental contaminants, yet relatively few analytical reference standards exist for this class...

Engineering Magnetic Anisotropy and Emergent Multidirectional Soft Ferromagnetism in Ultrathin Freestanding LaMnO3 Films

Author(s)
Qinwen Lu, Zhiwei Liu, Qun Yang, Hui Cao, Purnima P. Balakrishnan, Qing Wang, Long Cheng, Yalin Lu, Jian-Min Zuo, Hua Zhou, Patrick Quarterman, Shinichiro N. Muramoto, Alexander Grutter, Hanghui Chen, Xiaofang Zhai
Owing to their small coercive fields and weak magnetic anisotropy, soft ferromagnetic films are extremely useful for nanoscale devices that need to easily...

Value of information and decision pathways: Concepts and case studies

Author(s)
Pierre Glynn, Charles Rhodes, Scott Chiavacci, Jennifer Helgeson, Carl Shapiro, Crista Straub
Information plays a key role in the policy decision-making process – but the collection and dissemination of information carries costs. Understanding how these...

Indium Bump Process for Low-Temperature Detectors and Readout

Author(s)
Tammy Lucas, John Biesecker, W.Bertrand (Randy) Doriese, Shannon Duff, Gene C. Hilton, Joel Ullom, Michael Vissers, Dan Schmidt
We describe our indium bump process for low-temperature detectors and associated readout. A titanium nitride under bump metallization layer (UBM) is reactively...

Intrinsically accurate sensing with an optomechanical accelerometer

Author(s)
Benjamin Reschovsky, David Long, Feng Zhou, Yiliang Bao, Richard A. Allen, Jason J. Gorman, Thomas W. LeBrun
We demonstrate a microfabricated optomechanical accelerometer that is capable of percent-level accuracy without external calibration. To achieve this capability...
