Manipulation of meniscus rise for in situ multiphase nuclear magnetic resonance spectroscopy

April 8, 2025
Author(s)
Veruska Malave, Newell Moser, Edward Garboczi, Mark McLinden, Jason Widegren, Christopher Suiter
Our earlier work demonstrated that nuclear magnetic resonance (NMR) spectroscopy is a viable technique for in situ analysis of vapor–liquid equilibria (VLE) of fluid mixtures and that inserting a capillary into the NMR sample tube allows the simultaneous

Gauging error of pose acquired by vision systems in bin picking applications

April 7, 2025
Author(s)
Marek Franaszek, Prem Rachakonda, Kamel Saidi
Picking a part from an unorganized pile of parts requires an accurate vision system integrated with a robotic arm. A proper metric for gauging pose error is therefore indispensable. Pose error is a combination of an error in the position vector and an

Pyrrhotite Reference Material Synthesis

April 4, 2025
Author(s)
Michael Mengason, Stephanie Watson
The mineral pyrrhotite was synthesized from iron and sulfur starting materials for one component in a four-component reference material (RM 8154-Pyrrhotite in Concrete) to be used to evaluate the presence of sulfur in aggregate (crushed rock) and concrete

Acceleration-based spindle monitoring based on geometric error motions

April 3, 2025
Author(s)
Aaron Cornelius, Gregory Vogl, Ryan Hall, Yongzhi Qu
The development of intelligent machine tools requires integrating sensors that allow the machine to monitor, diagnose, and control the machining process. However, existing sensors for monitoring tool vibrations are intrusive and difficult to integrate in a

Inhibition by 4-(4-Bromo-2-oxo-3H-benzimidazol-1-yl)-N-(4-iodophenyl)piperidine-1-carboxamide) (TH5487) of the Activity of Human 8-Oxoguanine DNA Glycosylase-1 (OGG1) for the Excision of 2,6-Diamino-4-hydroxy-5-formamidopyrimidine, 4,6-Diamino-5-formamido

April 3, 2025
Author(s)
Pawel Jaruga, R. Stephen Lloyd, Michael Luzadder, Istvan Boldogh, M Miral Dizdar
DNA glycosylases of the base excision repair pathway have become clinically validated drug targets for treatment of several diseases. Human OGG1 (hOGG1) is specific for the removal of the highly mutagenic 8-oxoguanine (8-oxo-Gua) and 2,6-diamino-4-hydroxy

April 2, 2025
Author(s)
Newell Moser, Alexander Landauer, Orion Kafka
Image Processing in Python for 3D image stacks, or IMPPY3D, is a free and open-source software (FOSS) repository that simplifies post-processing and 3D shape characterization for grayscale image stacks, otherwise known as volumetric images, 3D images, or

Chapter 12 - Standard reference materials for the determination of trace organic constituents in environmental samples

April 1, 2025
Author(s)
Jessica Reiner, Bruce Benner, Jennifer Lynch, Jacolin Murray, Alix Rodowa, Meredith Evans Seeley, Katherine Shaw, Benjamin Place
Standard Reference Materials (SRMs) are homogeneous, well-characterized materials that are used to validate measurements and improve the quality of analytical data. NIST, the National Institute of Standards and Technology, has a wide variety of SRMs useful

Laser Beam Metrology for AM-Bench 2022: Approaches, Results, and Lessons Learned

April 1, 2025
Author(s)
David Deisenroth, Jordan Weaver, Sergey Mekhontsev, Steven Grantham, Shawn P. Moylan
One of key parameters of additive manufacturing by laser powder bed fusion of metal parts (PBF-LB/M) is the power density distribution (PDD) of the process laser beam. This paper describes the methods used to measure the beam PDD, discussing well
