Exploring the Possibility of Extrinsic Anion Vacancies in Li6PS5Cl

Abstract The search for superionic conductors requires a deep understanding of the underlying crystal structure and local dynamic processes. Therefore, cationic and anionic substitutions are typically performed to monitor the resulting changes in the structure and ionic transport...

The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites

Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...

Thermally Robust and Highly Wettable Polyethylene Separators for Lithium-Metal Batteries Using Water-Based Processing of a Glass Platelet Coating

Commercial polyolefin separators for lithium-ion batteries (LIBs) exhibit only inadequate wettability and thermal stability. In large-scale production, high electrolyte uptake and wetting are essential to enable rapid electrolyte filling during battery assembly to reduce costs. I...

Modeling of CO2-Based Fischer–Tropsch Synthesis over a Cu/Zn/K-Promoted Fe Catalyst: Influence of Reaction Kinetics and Multi-Fixed-Bed Reactor Design

CO2 hydrogenation by reverse water–gas shift (RWGS) directly combined with subsequent Fischer–Tropsch synthesis (FTS) in a single fixed-bed reactor represents a promising route for converting renewable hydrogen and captured carbon dioxide into hydrocarbons. However, the attainabl...

Spherical Metadensity Functional Learning for Inhomogeneous Classical Fluids

Abstract We develop classical density functional learning to address fluids with truncated pairwise interparticle interactions in three-dimensional spherical geometry. Simulation data for systems with randomized repulsive pair potentials provide the basis for supervised training...

Quantifying niche overlap and transgression in allopolyploid hybrids: Case study of Sorbus subgenus Aria

BACKGROUND AND AIMS: Apomixis, the formation of seeds without recombination, facilitates adaptation and persistence under environmental change. By preserving hybrid genotypes over long time periods, apomixis may conserve adaptive trait combinations from parental niche margins. We...

Parental niche construction buffers microbial and competitive challenges and drives offspring dependence in burying beetles

Parents across diverse taxa modify the biotic or abiotic environments of their offspring. Such modifications may constitute ecological inheritance and are central to developmental niche construction, whereby organisms shape developmental conditions and selective pressures experie...

The interplay of influencing factors in physical activity promotion for older men: insights through the capability approach

Abstract Background The capability approach has gained increasing attention in the context of health and physical activity promotion due to its focus on individuals’ freedoms to achieve desired outcomes. Its empirical application remains limited, particularly among older men, a g...

Pediatric Clostridium septicum infections: a systematic review and case-based perspective

Abstract Context Pediatric Clostridium septicum infections are extremely rare but often fulminant and rapidly progressive. They may manifest as clostridial myonecrosis, sepsis, or with gastrointestinal involvement. Systematic data on presentation, management, and outcomes remain...

Differences in the Thoracolumbar Fascia Between Low Back Pain Patients and Healthy Individuals: A Systematic Review with Meta-Analysis

Abstract Background In view of new evidence revealing a mechanical and nociceptive role of the thoracolumbar fascia (TLF), it has been suggested to be involved in low back pain. Objective To compare characteristics of the TLF in low back pain (LBP) patients and asymptomatic contr...

Distinct cellular responses in liver macrophages to short- and long-term exposure to pristine and artificially aged polystyrene microplastic particles

Microplastic particles (MPP) arise from mismanaged plastic waste, plastic degradation (i.e., agricultural films, textiles, or packaging), and direct use in products such as cosmetics. Their environmental persistence raises concerns for ecosystems, wildlife, and human health. Howe...

Brassinosteroid-regulated transcription factors confer epigenetic changes that repress plant immunity

Abstract When organisms encounter pathogens, they rapidly activate complex defense programs to ensure survival. While these immune responses are vital, they often also incur trade-offs, such as reduced growth and development and must therefore be tightly controlled 1,2 . In this...

Stellar Interpretation of Meteoritic Data and PLotting for Everyone (SIMPLE): Isotope Mixing Lines for Six Sets of Core-collapse Supernova Models

Abstract Bulk meteorites and their inclusions exhibit, for many chemical elements, isotopic variability produced by nucleosynthetic events in stars and supernovae before the formation of the Sun. While the exact astrophysical origins of these variations are still a matter of deba...

Oxidative Stressafter Pollutant Exposure DependsStrongly on Experimental Design and Pollutant Properties in Annelids:A Meta-Analysis

Abstract Measurements of oxidative stress are often performed to assess a species’ general sublethal stress response to a pollutant. However, oxidative stress bioassays often produce seemingly ambiguous results, and the drivers that lead to these differences are largely unknown....

Benchmarking local geometry optimization algorithms for computational materials discovery

Most current computational materials discovery workflows are dependent on efficient and reliable structure relaxations in order to predict a hypothetical material's equilibrium structure. Besides an accurate description of the potential energy surface, this requires efficient and...

Tailoring Trilayer LiTa 2 PO 8 ‐Based Hybrid Solid Electrolytes to Enhance Interfacial Compatibility and Efficient Lithium Transport in Lithium Metal Batteries

ABSTRACT Herein, a spatially decoupled trilayer hybrid solid electrolyte (THSE) is designed through functional architecture engineering to simultaneously optimize ionic conduction and interfacial stability. THSE integrates a polymer matrix comprising a Li + ‐conductive LiTa 2 PO...

Identifying the scale of effect of habitat for diversity and biomass of multiple arthropod taxa

Abstract Context Understanding how landscape composition influences biodiversity is a central objective of landscape ecology. Because species respond to environmental conditions across different spatial scales, landscape effects are inherently scale-dependent, making the identifi...

The German media debate on taxing meat and other animal-based foods: a framing analysis

OBJECTIVE: Consumption of meat - red and processed meat in particular - exceeds recommended levels in most high-income countries. Higher taxes on meat have been proposed as a response, but have proven difficult to implement due to political controversy. We examined the role of fr...

Smarter LCA : Using large language models to predict manufacturing processes and their uncertainties☆

Prospective Life Cycle Assessment offers significant potential to guide sustainable product development by influencing design in the early stages, when the flexibility for impactful changes is greatest. However, its practical application is often constrained by the limited availa...

Differential impact of fire, nitrogen fertilization, and unmanaged soils on the fungal mycobiome of rainfed maize

Maize ( Zea mays L.) is the second most cultivated cereal worldwide, covers approximately 27% of global cereal acreage, and remains a cornerstone of global food security. Climate warming increasingly threatens its yield in rainfed systems, driving the need for agronomic and genet...
