Magnetic Solitons in Hierarchical 3D Magnetic Nanoarchitectures of Nanoflower Shape.

Curvilinear magnetism emerged as a new route to tailor properties of magnetic solitons by the choice of geometry and topology of a magnetic architecture. Here, we develop an anodized aluminum oxide template-based approach to realize hierarchical 3D magnetic nanoarchitectures of nanoflower shape. The technique provides defect-free regular arrays of magnetic nanoflowers of tunable shape with a period of 400 nm over cm areas.

2025 Roadmap on 3D Nano-magnetism.

The transition from planar (2D) to three-dimensional (3D) magnetic nanostructures represents a significant advancement in both fundamental research and practical applications, offering vast potential for next-generation technologies like ultrahigh-density storage, memory, logic, and neuromorphic computing. Despite being a relatively new field, the emergence of 3D nanomagnetism presents numerous opportunities for innovation, prompting the creation of a comprehensive roadmap by leading international researchers. This roadmap aims to facilitate collaboration and interdisciplinary dialogue to address challenges in materials science, physics, engineering, and computing.

Targeting mono- and dual-species biofilms of Staphylococcus aureus and Pseudomonas aeruginosa by the recombinant anticoagulant enzyme PAPC from micromycete Aspergillus ochraceus.

Microbial biofilms have recently emerged as a critical target for treating bacterial infections due to their crucial role in developing antibiotic resistance. The wide-spectrum activity of proteolytic enzymes makes them particularly suitable for disrupting biofilms formed by diverse bacterial species, including dual-species biofilms. In this study, we propose the Protease-Activator of Protein C (PAPC) of human blood plasma, an enzyme produced by the micromycete Aspergillus ochraceus, as a novel tool to degrade the protein scaffold of mono- or dual-species biofilms formed by Staphylococcus aureus and Pseudomonas aeruginosa.

Antiferromagnetic Nanoscale Bit Arrays of Magnetoelectric CrO Thin Films.

Magnetism of oxide antiferromagnets (AFMs) has been studied in single crystals and extended thin films. The properties of AFM nanostructures still remain underexplored. Here, we report on the fabrication and magnetic imaging of granular 100 nm-thick magnetoelectric CrO films patterned in circular bits with diameters ranging from 500 down to 100 nm.

Derivatives of Pyrimidine Nucleosides Affect Artificial Membranes Enriched with Mycobacterial Lipids.

The mechanisms of action of pyrimidine nucleoside derivatives on model lipid membranes of various compositions were studied. A systematic analysis of the tested agents' effects on the membrane physicochemical properties was performed. Differential scanning microcalorimetry data indicated that the ability of nucleoside derivatives to disorder membrane lipids depended on the types of nucleoside bases and membrane-forming lipids.
