title: The database of ground-motion recordings, site profiles and amplification factors used for the development of the Groningen Ground-Motion Prediction Models

description: Induced earthquakes have occurred in the Groningen gas field in the Netherlands, since 1991, almost three decades after production began in 1963. As part of the Hazard and Risk Assment for the Groningen gas field, the field operator NAM (Nederlandse Aardolie Maatschappij BV) developed the Ground-Motion Model or Ground-Motion Prediction Model (GMM/GMPM) for spectral accelerations (Bommer et al., 2022a and b). The model translates seismicity to forces applied to buildings. With the model already published in said research articles, this data publication contains the data that were used to develop the model. This includes: (1) ground-motion recordings, (2) a field-wide shear-wave velocity and lithology model, (3) site characterization data at recording stations and (4) supplementary files, such as MATLAB code for the GMPM as well as key reports and papers. The published database is the result of an unprecedented data acquisition programme, lasting nearly 10 years, and is now provided openly by NAM BV, through EPOS-NL, the Dutch infrastructure for solid Earth sciences.

title: Conduction band tuning by controlled alloying of Fe into Cs2AgBiBr6 double perovskite powders

description: Halide double perovskite semiconductors such as Cs2AgBiBr6 are widely investigated as a more stable, less toxic alternative to lead-halide perovskites in light conversion applications including photovoltaics and photoredox catalysis. However, the relatively large and indirect bandgap of Cs2AgBiBr6 limits efficient sunlight absorption. Here, we show that controlled replacement of Bi3+ with Fe3+ via mechanochemical synthesis results in a remarkable tunable absorption onset between 2.1 and ~1 eV. Our first-principles density functional theory (DFT) calculations suggest that this bandgap reduction originates primarily from a lowering of the conduction band upon introduction of Fe3+. Furthermore, we find that the tunability of the conduction band energy is reflected in the photoredox activity of these semiconductors. Finally, our DFT calculations predict a direct bandgap when >50% of Bi3+ is replaced with Fe3+. Our findings open new avenues for enhancing the sunlight absorption of double perovskite semiconductors and for harnessing their full potential in sustainable energy applications.

title: Which Ion Dominates Temperature and Pressure Response of Halide Perovskites and Elpasolites?

description: Halide perovskite and elpasolite semiconductors are extensively studied for optoelectronic applications due to their excellent performance together with significant chemical and structural flexibility. However, there is still limited understanding of how their basic elastic properties vary with crystal orientation, composition and temperature, which is relevant for synthesis and device operation. To address this, we performed temperature- and pressure-dependent synchrotron-based powder X-ray diffraction (XRD). In contrast to previous pressure-dependent XRD studies, our relatively low pressures (ambient to 0.06 GPa) enabled us to investigate the elastic properties of halide perovskites and elpasolites in their ambient crystal structure. We find that halide perovskites and elpasolites show common trends in the bulk modulus and thermal expansivity. Both materials become softer as the halide ionic radius increases from Cl to Br to I, exhibiting higher compressibility and larger thermal expansivity. The mixed-halide compositions show intermediate properties to the pure compounds. Contrary, cations show a minor effect on the elastic properties. Finally, we observe that thermal phase transitions in e.g., MAPbI3 and CsPbCl3 lead to a softening of the lattice, together with negative expansivity for certain crystal axes, already tens of degrees away from the transition temperature. Hence, the range in which the phase transition affects thermal and elastic properties is substantially broader than previously thought. These findings highlight the importance of considering the temperature-dependent elastic properties of these materials, since stress induced during manufacturing or temperature sweeps can significantly impact the stability and performance of the corresponding devices.

title: Mass Transport Limitations in Polyolefin Cracking at the Single Catalyst Particle Level

description: Catalytic cracking is a promising approach to chemically recycle polyolefins by converting them into smaller hydrocarbons like naphtha, and important precursors of various platform chemicals, such as aromatics. Cracking catalysts, commonly used in the modern refinery and petrochemical industry, are tailored to process gaseous or liquid feedstock. Polyolefins, however, are very large macromolecules that form highly viscous melts at the temperatures required to break their backbone C-C bonds. Therefore, mass transport is expected to limit the performance of traditional cracking catalysts when applied to the conversion of polymers. In this work, we study these effects during the cracking of polypropylene (PP) over catalysts utilized in the fluid catalytic cracking (FCC) process. Thermogravimetric experiments using PP of varying molecular weight (Mw) and catalysts of varying accessibility showed that low Mw model polymers can be cracked below 275 °C, while PP of higher Mw required a 150 °C higher temperature. We propose that this difference is linked to different degrees of mass transport limitations and investigated this at lengths scales ranging from milli-  to nanometers, utilizing in-situ optical microscopy and electron microscopy to inspect cut open catalyst-polymer composites. We identified the main cause of transport limitations as the significantly higher melt viscosity of high Mw polymers, which prohibits efficient catalyst-polymer contact. Additionally, the high Mw polymer does not enter the inner pore system of the catalyst particles, severely limiting utilization of the active sites located there. Our results demonstrate that utilizing low Mw polymers can lead to a significant overestimation of catalyst activity, and suggest that polyolefins might need to undergo a viscosity reducing pre-treatment    in order to be cracked efficiently.

title: Kinetic insights into mechanochemical polypropylene depolymerization during ball milling

description: Mechanochemistry and specifically ball milling drives the depolymerization of commodity polymers with potential application for plastic recycling. The depolymerization is initiated by homolytic cleavage of the polymer chains and monomers cleave off from these activated chain ends. The efficiency of the process is determined by the cleavage rate but also by the number of monomers produced per chain end. This is influenced by side reactions such as recombination and disproportionation. The rates of these reactions are difficult to assess due to the transient nature of the radical intermediates. Here, we used radical scavenging combined with infrared spectroscopy to determine radical formation rates arising from backbone cleavage of polypropylene and perform microkinetic modelling of subsequent reactions. Monomer formation rates were determined with a ball mill setup that allows for online analysis of gaseous products. Microkinetic modeling revealed that reaction rate constants determined for thermal degradation underestimate the monomer formation rate during ball milling. This provides convincing evidence for the previously speculated destruction of a radical cage by the ball mill action. The termination reactions are suppressed by separating radicals in space through rigorous movement of the grinding spheres, increasing the efficiency of depolymerization.

title: Integrating the geological database of the subsurface of the Netherlands, for efficient visualization and interpretation

description: This data publication provides an integrated framework of the public geological database of the Dutch subsurface, for geological interpretation. It complements the extensive existing information portals available for public use by providing efficient visualization and interpretation of geologically relevant information at the scale of the entire country. The relevant dataset is integrated into a single Schlumberger PetrelTM project, while the reflections seismics and wells dataset is provided separately in platform-independent formats with included metadata. While the Petrel software utilized in this project requires a commercial license, it is widely used within both industry and academia, and we anticipate that this data publication can be utilized by a wide audience. We emphasize that all data and models integrated in this project are in itself publicly available, and maintained so by the Dutch Geological Survey of TNO. Among others, the present project integrates 10,599 2D seismic lines, 280 3D seismic cubes, 6,590 wells and 4,752 composite wells logs. The project is not exhaustive in terms of all available subsurface data in the Netherlands and should be considered as providing an easier start for anyone interested in visualizing and interpreting the Netherlands subsurface. The present publication on Yoda data services includes version 3.4 of the Petrel project. The most recent version can be found in a publicly accessible SURF drive: https://uu.data.surfsara.nl/index.php/s/hOEuDK2a5NmuWiw, along with the large seismic dataset referred to in the Petrel project. If you encounter any issues in accessing the dataset on Yoda or on SURF, please contact info@epos-nl.nl.
