Scintillation properties of multilayered composite scintillators based on the YAG:Ce and TbAG:Ce single crystalline films and GAGG:Ce crystal substrates
No full textThis work demonstrates current progress of our group in developing of two- and three-layered composite for radiation monitoring of various components of mixed ionization radiation fluxes based on the epitaxial structures of Ce3+ doped garnet compounds using the Liquid Phase Epitaxy growth technique. These scintillators contain one or two single crystalline films, dedicated for registration of low-penetrating particles, and bulk single crystal substrates used for detection of high-penetrating γ-rays. For creation of two- and three-layered epitaxial structures, the single crystalline films of Ce3+ doped Y3Al5O12, Tb3Al5O12 and Tb2GdAl5O12 garnets were used. The single crystal of mixed Gd3GaxAl5-xO12:Ce garnet with fixed Ga concentrations of x = 2.3 and 3.0 are utilized as substrates. To assess the scintillation properties of these epitaxial structures, the pulse height spectra, light yield and scintillation decay kinetics were measured under excitation by α–particles (239Pu), β-particles (90Sr + 90Y) and γ–rays (137Cs). Finally, the figure-of merit of composite scintillators under study were calculated for selection of the best epitaxial structures for simultaneous registration α– and β-particles and γ–rays.</p

Dataset for AQUE TNA of ATMO-ACCESS: Large eddy simulations of chemical species with PALM model in urban environment, Warsaw, Poland
No full textOverviewThis dataset contains numerical simulation outputs from the AQUE (Air Quality in Urban Environment: A Focused Study on Pollution Behavior in Warsaw's Canopy Layer) project, conducted as part of transnational access (TNA) program of ATMO-ACCESS pilot funded by European Commission. The model simulations were performed for two intensive observational campaigns conducted in July and October 2024 of the AQUE TNA. For modelling we were using the LES-PALM and Code_Saturne models. The central reference point for the simulations is the Warsaw Observatory Station at the Institute of Geophysics, Faculty of Physics, University of Warsaw (52°12'39.6" N, 20°58'57.4" E, 132 m a.s.l.).This data slot contains LES-PALM simulations only. The Code_Saturn simulations are published in separate data slot.PALM simulations dataThe PArallelized LES Model (PALM) was used for high-resolution numerical large eddy simulations (LES) to analyze turbulence within the planetary boundary layer (PBL). Originally developed by Raasch and Schröter (2003) and later expanded by Maronga et al. (2015, 2020), PALM is optimized for massively parallel computing. Version 6.0, developed by the Institute of Meteorology and Climatology at Leibniz University Hannover, was employed in this study. The model includes the PALM core and PALM-4U (for urban applications), integrated as part of the MOSAIK project for climate-sensitive urban planning. PALM resolves large-scale turbulence explicitly while parameterizing small-scale eddies using a 1.5-order closure scheme (Deardorff). It employs a Cartesian grid, the Boussinesq approximation, and a third-order Runge-Kutta time-stepping scheme. Advection is handled with a fifth-order Wicker and Skamarock scheme, and surface-atmosphere interactions follow the Monin–Obukhov similarity theory (MOST). Prognostic variables include 3D wind components (u, v, w), potential temperature (θ), water vapor mixing ratio (qv), a passive scalar (s), and subgrid-scale turbulent kinetic energy (SGS-TKE) (Scherer et al., 2019).The Version 6.0 LES-PALM model was setup and run at the Interdisciplinary Centre for Mathematical and Computational Modelling University of Warsaw (ICM UW).The published here dataset consists of outputs from high-resolution numerical simulations conducted using the PALM model. The simulation covers a 6.0 km × 6.0 km horizontal domain and extends up to 4.0 km in the vertical. The model setup was aligned with the geographic coordinates of the rooftop platform of the Warsaw Observatory Station at the Institute of Geophysics, Faculty of Physics, University of Warsaw (52°12'39.6" N, 20°58'57.4" E, 132 m a.s.l.). The dataset provides high-resolution meteorological variables, including wind fields, temperature, turbulence characteristics, and concentrations of NO₂, NO, O₃, and PM₁₀, enabling a comprehensive analysis of air quality dynamics within Warsaw’s urban canopy layer.The static input file (Warsaw_6km_static.nc) contains the static information about the topography, as well as all the data needed to initialize the land and urban surfaces in the model. This includes building heights, street types, vegetation types, land use and land cover, and more within the simulated domain and following the degree spacing. The surface initialization process follows a multi-step approach, depending on the level of detail available for each variable specified in the static file.The PALM data slot includes the following files:palm_OUTPUT_pr_YYYYMMDD.ncpalm_OUTPUT_ts_YYYYMMDD.ncpalm_OUTPUT_xy_YYYYMMDD.ncpalm_OUTPUT_masked_YYYYMMDD.ncWarsaw_6km_static.ncRadiosounding at Legionowo, Poland (WMO 12374)Radiosonde data from the Legionowo station (WMO 12374, 52°24'00.0" N, 20°57'36.0" E, 96 m a.s.l.) were used as input files for the PALM model simulations.Soundings were conducted at 00:00 and 12:00 UTC, providing atmospheric profiles of atmospheric pressure (PRES, hPa), geometric height (HGHT, m), air temperature (TEMP, °C), dew point temperature (DWPT, °C), relative humidity (RELH, %), mixing ratio (MIXR, g/kg), wind direction (DRCT, degrees), wind speed (SKNT, knots), potential temperature (THTA, K), potential equivalent temperature (THTE, K), and potential virtual temperature (THTV, K).These profiles offer a detailed information on the thermodynamic structure and meteorological conditions throughout the atmospheric column on the campaign days.NOTE: These data are also accessible (and can be visualized) via the Atmospheric Soundings Portal at the University of Wyoming (https://weather.uwyo.edu/upperair/sounding.html, last access February 11, 2025).The Radiosounding data includes the following files:Soundings_YYYY-MM-DD-hh.txtIn-Situ measurements from CIEP in Warsaw, PolandAir quality data from monitoring stations operated by the Chief Inspectorate for Environmental Protection (CIEP) in Warsaw, Poland, were used to establish the initial chemical conditions for the PALM simulations. For this purpose, historical monthly average data from the years 2021, 2022 and 2023, corresponding to the months of the AQUE TNA campaigns, were used.The CIEP dataset includes surface-level concentrations of key air pollutants such as nitrogen dioxide (NO₂), ozone (O₃), particulate matter (PM₁₀), and other air pollutants, measured at CIEP air quality monitoring stations.Measurements collected from multiple urban background locations, excluding the communication/traffic station, provided information in hourly resolution for different areas of the city.The data are also accessible through the Measurement Data Archives of the Chief Inspectorate of Environmental Protection (CIEP) (https://powietrze.gios.gov.pl/pjp/archives, last access February 11, 2025).The CIEP data includes the following files:YYYY_NO.xlsxYYYY_NO2.xlsxYYYY_O3.xlsxYYYY_PM10.xlsxFile InformationThe LES-PALM output data and static file are stored in netCDF format (.nc), with variables provided for each day at 30-minute intervals.

Microfluidic-Mixer Assisted 3D Printing of Functionally Graded Multimaterial Hydrogels for Engineering Complex Tissue Interfaces
No full textReconstructing complex tissue interfaces like the osteochondral junction requires biomaterials that mimic native gradients in mechanical, biochemical, and structural properties. Traditional methods often fail to produce continuous transitions within a single construct. To address this, we developed a microfluidic-assisted 3D printing platform using a passive micromixer with a flow-focusing junction (mix-ff-MPH) as the printhead. This enables real-time control of polymer composition and density, allowing the fabrication of functionally graded porous hydrogels (FGPHs) with smooth gradients. Optimized micromixer designs achieved high mixing efficiency (index ≥ 0.8), ensuring uniform integration of bioinks like GelMA and DexMA. The constructs showed spatially controlled porosity and composition, confirmed by confocal microscopy and FTIR. When seeded with 3T3 fibroblasts, the scaffolds supported region-specific cell adhesion and viability, demonstrating the role of local properties in guiding cell behavior. This platform offers a precise and versatile approach to engineering graded tissue scaffolds, with strong potential for regenerative medicine.</p
