Interlaboratory comparison of cavity resonator measurements for complex permittivity to 170 GHz

Figure data for "Interlaboratory comparison of cavity resonator measurements for complex permittivity to 170 GHz"ABSTRACT:Standards provide known right answers traceable to National Metrology Institutes. Today, no such complex permittivity standard exists, let alone one traceable to the International System of Units (SI). In response, a consortium of industrial, academic, and government laboratories - led by the International Electronics Manufacturing Initiative (iNEMI) - performed an interlaboratory comparison to understand the impact of this problem and how a new standard could help. The goal of the comparison was to benchmark the best-case interlaboratory agreement in complex permittivity measurements up to 170 GHz and provide some industry-led guidance for making the standard useful. The consortium used four different types of commercial resonators from 10 GHz to 170 GHz. Here, we show how we improved the best-case repeatability and interlaboratory agreement of these resonator measurements. We leverage the broader capabilities of nine industry (e.g., Intel, Panasonic, 3M) and government (e.g., NIST, ITRI) labs worldwide in the four interlaboratory comparisons presented here. These interlaboratory comparisons quantify interlaboratory agreement and incorporate stakeholder feedback to develop a fit-for-purpose standard for complex permittivity.

The U.S. Greenhouse Gas and Air Pollutant Emissions System (GRA2PES)

To bridge the gap between the development of greenhouse gas (GHG) and air quality (AQ) emission inventories, we developed the GReenhouse gas And Air Pollutant Emissions System (GRA2PES), which provides self-consistent GHG and AQ emissions over the contiguous U.S. This inventory provides emissions at 4 km x 4 km spatial resolution with year, month, day-of-week, and diurnal temporal information. GRA2PES utilizes datasets from the U.S. Energy Information Administration (EIA) and the U.S. Environmental Protection Agency (EPA), and leverages a few well evaluated inventories for specific sectors, including the Fuel-based Oil and Gas (FOG) inventory, the Fuel-based Inventory of Vehicle Emissions (FIVE), and the Volatile Chemical Products (VCP) inventory. GRA2PES provides knowledge of the characteristics of AQ and GHG emissions and their relationships at finer mitigation spatiotemporal scales, which is fundamentally important for modeling AQ co-benefits of GHG emissions reductions. Also, as a self-consistent GHG and AQ emissions inventory, GRA2PES can be utilized in multi-species joint data assimilation (DA) of GHG and AQ emissions, enabling source appointment. We aim to provide GRA2PES as a dataset to inform integrated assessments of climate and air quality for researchers, stakeholders, and policymakers.

Incorporating dynamic bonds into high density polyethylene for upcycled plastic waste

This dataset consists of characterization of telechelic functional polyethylene oligomers, precursors, and resultant step-growth polyethylene with urethane-linkages between segments of different lengths.  Polymer characterization data includes nuclear magnetic resonance (NMR) spectra, room-temperature and high-temperature size exclusion chromatography data and associated calibration curves, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectra, transmission FTIR spectra with melting.  Several physical measurements were also conducted on the materials in this study and are included in this data asset: differential scanning calorimetry (DSC) measurements, rheological measurements, micro ballistic impact measurements, small angle and wide angle x-ray scattering (SAXS and WAXS, respectively),This is the abstract for the manuscript written using the data provided herein."Over 50% of plastic waste comes from a single class of semi-crystalline polymers called polyolefins. While direct mechanical recycling of these plastics would be highly advantageous, most recycling strategies fail to preserve the broad molecular mass distribution of these polyolefins, from which they derive their unique combination of processability and mechanical strength. Here, we show that the incorporation of reversible interactions into high-density polyethylene (HDPE) can circumvent this issue, by strengthening the amorphous phase through interchain supramolecular interactions, as opposed to traditional entanglements from high molecular mass chains. Critically, we show that many key properties of these dynamic HDPE polymers, including percent crystallinity, melting temperature, bond association, and mechanical properties are determined by the distribution of bond-to-bond spacings along the chain backbone and can be predicted using simple polymer physics theories. Through X-ray scattering experiments, we show that a mixed backbone HDPE dynamic polymer exhibits a unique display of long-range supramolecular order that persists even in the melt state along with mechanical properties that exceed HDPE and approach the strain-hardening behavior seen in ultra-high molecular weight polyethylene. This work demonstrates a promising mechanism for upcycling of polyolefin waste, illuminates key fundamental principles governing how the placement of dynamic bonds in polyolefins can dramatically influence bulk material properties, and provides a framework to design new upcycled polymers based on controlling bond-spacing distributions."

Data associated with "Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms"

Rydberg states of alkali atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently, environmental blackbody radiation (BBR) can couple Rydberg states together at ?s timescales. Here, we track the BBR-induced transfer of a prepared Rydberg state to its neighbors and use the evolution of these state populations to characterize the BBR field at the relevant wavelengths, primarily at 130 GHz. We use selective field ionization readout of Rydberg states with principal quantum number n?30 in 85Rb and substantiate our ionization signal with a theoretical model. With this detection method, we measure the associated blackbody-radiation-induced time dynamics of these states, reproduce the results with a simple semi-classical population transfer model, and demonstrate that this measurement is temperature sensitive with a statistical sensitivity to the fractional temperature uncertainty of 0.09 Hz?1/2, corresponding to 26 K?Hz?1/2 at room temperature. This represents a calibration-free SI-traceable temperature measurement, for which we calculate a systematic fractional temperature uncertainty of 0.006, corresponding to 2 K at room temperature when used as a primary temperature standard.Included in this dataset is the data associated with every plot in the paper, separated by figure number.
