ZenoWrapper: Accessing Hydrodynamic and Electronic Properties through MDAnalysis

Data provided by  National Institute of Standards and Technology

ZENO computes hydrodynamic and electronic properties using numerical path integration techniques based on Brownian motion Monte Carlo methods. These methods provide stochastic solutions to elliptic partial differential equations, which represent the desired material properties or serve as intermediates for their computation. The mathematical framework maps these problems onto the electrostatic capacitance problem, where the stochastic solution corresponds to the probability of a random walk from infinity hitting the material's surface.

Data for “Quantifying rheology and microstructure of hydrating Portland-Limestone Cement blends to address additive manufacturing needs”

Data provided by  National Institute of Standards and Technology

These data are associated with the paper “Quantifying rheology and microstructure of hydrating Portland-Limestone Cement blends to address additive manufacturing needs” by the same authors [1]. The data are associated with in situ dielectric rheological small-angle neutron scattering (rheo-SANS) studies of Portland limestone cement (PLC) blends and Ordinary Portland Cement (OPC) control [2]. The rheo-SANS data were collected on the NIST Center for Neutron Research (NCNR) VSANS instrument [3] as a function of cement hydration time.

Traceable Validation of Calculable Quantum-Based RF Waveforms

Data provided by  National Institute of Standards and Technology

We compare the calculated, quantum-based output of a radio-frequency Josephson arbitrary waveform synthesizer (RF-JAWS) with its measured output that is calibrated through the established NIST RF power traceability path, a necessary first step towards quantum-based RF metrology. An array of

Evaluation of a new Prototype of Secondary Voltage Standard with a Programmable Josephson Voltage Standard

Data provided by  National Institute of Standards and Technology

This paper evaluates the short-term and long-term performance of a new type of dc secondary voltage standard at 10 V by direct comparison to a programmable Josephson voltage standard. Allan deviation measurements indicated a noise floor of 4.5 nV, enabling potential new applications in voltage metrology and possibly reducing uncertainty along the dissemination chain from primary calibration laboratories to calibration laboratories.

SpherIndent: An open-source python software for calibration, analysis and visualization of spherical nanoindentation experiments

Data provided by  National Institute of Standards and Technology

SpherIndent is a modular, open-source software package with graphical user interface (GUI) for analysis of quasi-static spherical indentation experiments conducted in single-step or multi-step loading sequences. All components are developed in Python programming language with the GUI built on Tkinter. The software package is essentially constructed using libraries including NumPy, Pandas, SciPy, Sklearn, Matplotlib, and OpenCV. Data storage, from raw to processed and analyzed data (including figures) is handled via Pickle with traceability, efficient retrieval and sharing in mind.

Compact 2 V Cryocooled Programmable Josephson Voltage Standard for Direct On-Site Quantum Voltage Comparisons

Data provided by  National Institute of Standards and Technology

This paper evaluates the performance of a new type of 2 V traveling cryocooled Programmable Josephson Voltage Standard for performing on-site verification of quantum voltage standards. Direct comparison with a 10 V system showed agreement of 8 parts in 10^11 at 2 V. This result shows that, despite the lower voltage, the direct Josephson-to-Josephson system comparison method provides a two orders-of-magnitude improvement over traveling Zener standards for verifying Josephson voltage standards.
