Selecting the complexity of the Moore-Penrose pseudoinverse for emission ghost imaging

December 2, 2025
Author(s)
Kevin Coakley, Huaiyu Chen-Mayer, Bruce Ravel, Daniel Josell, Nikolai Klimov, Daniel Hussey
We reconstruct X-ray fluorescence signals produced by synchrotron X-rays. In our method, we select the complexity of a Moore-Penrose pseudoinverse by a data-driven method, and study how systematic errors affect results for simulated data.

Twin-related grain boundary engineering of additively manufactured 316L stainless steel

December 1, 2025
Author(s)
Chenglu Tang, Jingfan Yang, Fan Zhang, Joseph Aroh, Ernest Porterfield, Barton Prorok, Xiaoyuan Lou
Twin-related grain boundary engineering (GBE) enhances the boundary-related degradation of materials, such as intergranular corrosion by incorporating a high density of twin boundaries. Conventional GBE typically requires one or multiple thermomechanical

Wind-Driven Fire Spread to a Structure from Composite Fences

November 26, 2025
Author(s)
Kathryn Butler, Erik Johnsson, Marco Fernandez, Shonali Nazare, Alexander Maranghides
Field observations show that combustible landscaping features are a common pathway leading fire spread directly to homes during wildland-urban interface (WUI) fires. NIST is studying how these features near a home burn to better understand their levels of

Charge-state dependent ion condensation near conjugated polymer backbones

November 15, 2025
Author(s)
Dilara Meli, Quentin Thomas, Guillaume Freychet, Lucas Flagg, Iain McCulloch, David Beljonne, Lee Richter, Jonathan Rivnay
Despite the technological appeal of organic mixed ionic/electronic conductors (OMIECs) for a range of applications, a deep understanding of the fundamentals of mixed charge transport in these materials, especially regarding the ionic component, is lacking

Topology-dependent polymer stretching and scission in solution at extreme shear rates

October 23, 2025
Author(s)
Bas van Ravensteijn, Patrick Corona, Anukta Data, Kexin Dai, Raghida Bou Zerdan, Kathleen Weigandt, Ryan Murphy, Craig Hawker, Matthew Helgeson
There has been significant recent interest in engineering polymer topology to control rheology and mechanical stability in dilute solutions for applications involving extreme shear rate flows. However, methods to experimentally probe properties at relevant

Bayesian Inference of Anisotropic 2D Small-Angle Scattering from Sparse Measurement

October 15, 2025
Author(s)
Chi-Huan Tung, Yangyang Wang, Jan-Michael Carrillo, Yuya Shinohara, Chun-Yu Chen, Jhih Lin, Lionel Porcar, Ryan Murphy, Guan-Rong Huang, Lijie Ding, Changwoo Do, Wei-Ren Chen
We present a Bayesian inference framework for reconstructing anisotropic two-dimensional small-angle scattering (2D SAS) patterns from sparse, noisy, or partially missing data. The method combines a symmetry-aware angular basis with radial Gaussian process

Feasibility Study of a Neutron-based Method for Field Measurement of Chloride in Concrete

September 30, 2025
Author(s)
Huaiyu Chen-Mayer, Shannon Hoogerheide, Aiysha Ashfaq, Jacob LaManna, Scott Jones, Mohamad Al-Sheikhly, Richard A. Livingston
Chloride in concrete is known to promote corrosion of the interior metal enforcement which leads to structural degradation. Chloride content monitoring is an important task for maintaining infrastructure integrity. The current industrial practice of

Evaluation of Variations in Solution Annealing, Intercritical Annealing, and Aging Treatments on Cobalt-free Maraging Steels

September 22, 2025
Author(s)
Nicholas Derimow, Jake Benzing, Alec Saville, Cassidy Allen, Jordan Weaver, Nikolas Hrabe, Timothy Quinn, Timothy Weeks, Newell Moser, Chad Beamer, Christin Aumayr, Tilman Seifert, Michael Hirtler
This work is a compilation and summary of the quasi-static mechanical properties of a novel cobalt-free maraging steel, M789, that underwent a series of various heat treatments which included solution annealing, intercritical annealing, and aging

PMSE Centennial: Celebration of Success and New Frontiers in Polymer Materials Science and Engineering

Mellissa Grunlan, LaShanda Korely, Qinghuang Lin, Christopher Soles, Rigorberto Advincula, Arthi Jayaraman, Elizabeth Cosgriff-Hernandez, Elsa Reichmanis, Jodie Lutkenhaus, Rodney Priestly, Bridgitte Voit, Thomas Epps
In 2024, the American Chemical Society (ACS) Division of Polymeric Materials: Science and Engineering (PMSE) marked celebrated its centennial. This historic occasion was marked at the 2024 Spring ACS Meeting in New Orleans with a Centennial Symposium

Effects of Silica, Fe(II), and Mn(II) on Electrochemical Lithium Intercalation: Implication for Lithium Extraction from Geothermal Brines

September 11, 2025
Author(s)
Yongchang Yu, Christopher Stafford, Lingchen Kong, Keven Mckenzie Jr, Michael Wagner, Xitong Liu
Electrochemical lithium intercalation is a promising direct lithium extraction technology owing to its high lithium selectivity and elimination of chemical usage, making it an environmentally friendly solution for lithium extraction from geothermal brine

Intrinsic Direct Air Capture

September 10, 2025
Author(s)
Austin McDannald, Daniel Siderius, Brian DeCost, Kamal Choudhary, Diana Ortiz-Montalvo
How can you tell if a sorbent material will be good for any gas separation process – without having to do detailed simulations of the full process? We present new metrics to evaluate solid sorbent materials for Direct Air Capture (DAC), a particularly

Symmetry-breaking induced surface magnetization in non-magnetic RuO2

September 8, 2025
Author(s)
Quoc Dai Ho, Quang To, Ruiqi Hu, Garnett Bryant, Anderson Janotti
Altermagnetism is a newly identified phase of magnetism distinct from ferromagnetism and antiferromagnetism. RuO2 has been considered a prototypical metallic altermagnet with a critical temperature higher than room temperature. Previous interpretations of

Quantum Vibro-Polaritonic Sensing

August 15, 2025
Author(s)
Peng Zheng, Stephen Semancik, Ishan Barman
Vibrational spectroscopies are pivotal in analytical methods and biomedical diagnostics owing to their singular ability to provide molecular specificity. Yet, they are intrinsically limited by weak light-matter interactions and their vulnerability to

Interfacial Alloying Contributions to the Magnetic Proximity Effect in Pt/Dysprosium Iron Garnet
