title: Database of ATR-FTIR, Raman spectroscopy, and X-ray diffraction reference data for battery interphase components

description: This dataset contains ATR-FTIR, Raman spectroscopy, and X-ray diffraction reference data for 10 common components of electrode-electrolyte interphases in rechargeable lithium-based batteries: lithium acetate (CH3COOLi), lithium carbonate (Li2CO3), lithium fluoride (6LiF and 7LiF), lithium hydride (LiH), lithium hexafluorophosphate (LiPF6), lithium oxide (Li2O), manganese(II) fluoride (MnF2), nickel(II) fluoride (NiF2), and polyethylene oxide (H(OCH2CH2)nOH). The deposit includes both raw and processed data, along with background subtraction fits and normalized spectra. Raw Raman data axes were interpolated to apply Fourier transform filtering.

title: Postharvest insect pests of walnuts in Northwestern Argentina and their associated natural enemies

description: RESUMEN

Una fuente importante de pérdidas económicas en la agricultura son las plagas postcosecha. En Argentina, el control de plagas se basa principalmente en agroquímicos, cuya aplicación segura requiere infraestructura que, a menudo, no está disponible para los pequeños productores. Las estrategias alternativas, como el control biológico, ofrecen una opción más sostenible, económica y ecológica. Se relevaron las áreas de almacenamiento postcosecha en 22 fincas de nogales en cinco localidades de la provincia de La Rioja, durante 2017 - 2018. Se identificaron insectos plaga de las órdenes Coleoptera y Lepidoptera, y sus parasitoides. Se registrará la abundancia relativa, el porcentaje de daño a la fruta, el índice de infestación y la tasa de parasitismo. Los huertos a menor altitud, con temperaturas más altas y un almacenamiento deficiente (común en los pequeños productores) fueron más vulnerables a las infestaciones de coleópteros. Este estudio proporciona el primer registro de Carpophilus truncatus (Murray, 1864) y C . hemipterus (Linnaeus, 1758) en la provincia, ambos vinculados al mayor daño poscosecha. Se identificaon cuatro parasitoides himenópteros y dos morfoespecies de dípteros, todos con uso conocido en biocontrol. Se requiere mayor investigación para seleccionar las especies de parasitoides más adecuadas para el biocontrol específico en el noroeste de Argentina. Este es el primer reporte del parasitoide Cephalonomia tarsalis (Ashmead, 1893) en La Rioja.

title: Dataset for the hydrogen 2S-6P transition measurement at MPQ

description: Condensed dataset for the hydrogen 2S-6P transition measurement at the Laser Spectroscopy Division of the Max Planck Institute of Quantum Optics (MPQ). The measurement is described in [1] and [2]. The dataset is condensed in the sense that the fluorescence signal has been binned into velocity groups (or delays) and only summary statistics of auxiliary analog input data are provided, and only data used in the analysis of [2] are included.
