title: Dataset for Return for reuse plastic food packaging: simulated wear processes and assessment techniques

description: There is a need for research to support the transition away from single-use plastic packaging towards a circular economy. This research developed simulated wear processes and assessment techniques to evaluate the suitability of plastic food packaging types for reuse systems. Two thermoformed polyethylene terephthalate materials (rPET and heat-resistant PET) for food packaging trays were tested. We subjected both thermoformed packs to a range of simulated wear processes to emulate aspects of a potential reuse system, including wash cycles, simulated damage, surface scratching, and artificial fouling. Assessment techniques included using adenotriphosphate (ATP) swabs to determine cleanliness of the pack surface, and 3D scan data to measure physical change. The findings show that scratch damage applied to packs, following fouling and wash cycles, are food safe with readings under 30 relative light units (RLU) on ATP swabs. The heat-resistant PET packs exhibited minimal deformation throughout repeated wash cycles, demonstrating its appropriateness for a reuse system. The assessment techniques developed to evaluate the suitability of plastic materials for reuse systems have provided valuable insight into the cleaning, damage, and deformation of plastic packaging. These insights can support more complex decision making in the design and production of circular food-to-go plastic packaging solutions.The file presented here contains, and makes open access, all data that underpins the manuscript: <b>Return for reuse plastic food packaging: simulated wear processes and assessment techniques</b>

title: Hadamard conjecture proof

description: This paper presents a complete resolution of the Hadamard Conjecture, which posits that a Hadamard matrix of order 4n exists for every positive integer n. By combining recursive constructions, Kronecker product expansions, and Paley-type matrices, the paper confirms that orthogonal ±1 matrices of order 4n can always be constructed. The proof validates orthogonality through inner product trace calculations and generalizes the method across all n, concluding that Hadamard matrices exist for all orders divisible by 4. This resolution has wide-ranging implications in coding theory, cryptography, and combinatorics.

title: 3D datasets for 60 nm Gold Nanoparticles

description: The image data (in .mrc format) were collected with the Helmholtz-Zentrum Berlin transmission soft X-ray microscope (TXM) and used for comparison to predictions of a 3D imaging model for such a microscope. The detailed analysis is presented in the publication “Towards a quantitative theory for transmission X-ray microscopy” by McNally et al. in the Beilstein Journal of Nanotechnology (2025).
The files beginning with “Dataset 1,2 or 3” correspond to the data presented in Fig. 2 of the publication. These data reflect a set of through-focus 2D images of ~60 nm gold nanoparticles acquired from the microscope at 510 eV with a pixel size of 5.47 nm and a z spacing of 40 nm.
The remaining files, all beginning with “GoldNP”, correspond to the data presented in Fig. 5 of the publication. Each filename includes a number (directly after “GoldNP”) corresponding to the diameter of the gold nanoparticle (in nm) as measured by scanning electron microscopy. The energy is again 510 eV and the pixel size is again 5.47 nm. These images were all collected in the same focal plane of the nanoparticle, namely its best focus. That best-focal-plane image is then acquired ten times, leading to the ten images in the stack.

description: This data set contains N2O (nitrous oxide) efflux rates measured within SPRUCE experimental plots in 2024. N2O is a gaseous N species formed during the microbial processes of denitrification and ammonia oxidation, and is a powerful greenhouse. Measurements were made manually with a LiCor N2O/H2O analyzer (LI-7820) and paired SmartChamber (LI-8200-01S) in June, August, and October (2024-06-24 to 2024-10-22). During each measurement, the SmartChamber was placed on 8” PVC collars that were installed in May 2024. N2O flux was derived from 10-minute flux measurements processed using SoilFluxPro software (v5.3.1) and fit to a linear model. Model slope and R2 are reported along with soil water, soil temperature, and air temperature observations made with SmartChamber sensors. This dataset contains one data file in comma separate (*.csv) format.
