Summary: Recent experiments have shown that two-dimensional (2D) magnetism has attracted strong interest in advanced spintronics applications. However, the limited Curie temperature and magnetic anisotropy energy (MAE) hinder their potential applications. Through density functional theory calculations, we have predicted a stable 2D monolayer of Na3VAs2, which exhibits intrinsic ferromagnetic (FM) order and a high MAE (570 μeV per V atom). Monte Carlo simulation reveals that this monolayer has a Curie temperature (TC) of up to 305 K based on anisotropic Heisenberg mode. In addition, the 2D Na3VAs2 monolayer exhibits ideal half-metallic properties, which are maintained under various strains, and possesses good dynamic, thermal, and mechanical stability. The exceptional properties of the Na3VAs2 monolayer make it a promising candidate for spintronic devices.

Summary: VANs are a novel tool for strain engineering of physical properties in nanostructures, consisting of two or more phases intertwined along vertical interfaces. The unique nanoarchitecture can be tuned by choosing appropriate growth conditions to control the magnetic properties of the nanocomposites. Possible extensions to more than one embedded metallic phase and remaining challenges in creating novel functional nanoarchitectures are also discussed.

Summary: Dense systems of magnetic nanoparticles can exhibit collective behavior, and it remains unclear whether the transition temperature is influenced by particle anisotropy or determined by interparticle dipolar interactions. Additionally, the minimum ratio of dipole-dipole interaction to nanoparticle anisotropy energies necessary for the crossover from individual to collective behavior is unknown. This study investigates particle assemblies with varying anisotropy and finds a threshold value to suppress collective behavior. The findings have practical applications in predicting the behavior of interacting particle assemblies.

Summary: High-sensitivity magnetometry is crucial for biomagnetism and geomagnetism. However, the sensitivity improvement for dc and low-frequency signal detection is challenging due to the presence of low-frequency noise from various sources. In this study, we utilized a flux concentration and modulation technique to convert dc magnetic signals to ac, allowing for the application of dynamical decoupling to prolong the dephasing time. As a result, we achieved a sensitivity of 32 pT/Hz(1/2) in a dc magnetometer, which is two orders of magnitude higher than that of the Ramsey-type dc magnetometer. Although further enhancement of sensitivity is challenging, there is still considerable room for improvement. Our findings provide insight into the future realization of room temperature dc quantum magnetometry with femtotesla sensitivity.

Summary: This study presents a water-soluble method to prepare flexible magnetic heterostructures with periodic wrinkle patterns. High-quality ferroelectric membranes are successfully fabricated on flexible substrates, enabling controllable ferromagnetic resonance fields and magnetoelectric effects. The proposed ultraflexible wrinkle sample shows great potential for combining multiple magnetization tuning approaches, allowing it to potentially serve as a tunable high-density 3D storage prototype.

Summary: The presence of diverse pollutants in water poses a threat to human health and aquatic ecosystems globally. Chemical oxidation has been an effective technology for pollutant destruction, but faces challenges in treating emerging micro-pollutants. There are various examples of selective oxidation strategies in water treatment, but a systematic understanding of selectivity origins and rational catalyst design is still lacking.

Summary: Chemical guidelines that target a well-defined electronic structure and magnetic anisotropy play a crucial role in physics, chemistry, and biology. Our literature overview emphasizes that manipulating the energy gap between the ground and first excited state and customizing the magnetic anisotropy of paramagnetic molecules serve as excellent starting points for enhancing the performance of various molecular materials with emerging technological properties. These materials include Single Molecule Magnets, Pseudo Contact Shift agents, Optically Addressable Qubits, Magnetic Refrigerants, and Magnetic Anisotropy Switches. Furthermore, we discuss the compatibility between different functionalities.

Summary: Stress-dependent micromagnetic modeling based on the Landau-Lifshitz-Gilbert equations reveals the significant relationship between uniaxial stress in ferromagnetic thin films and pumped spin current density, influencing the static and dynamic magnetization. The ability to dynamically modulate the pumped spin current density through stress-mediated magnetoelectric coupling is anticipated to benefit various spintronic applications.

Summary: The present study focuses on the supramolecular host-guest complexation of OCASP into b-CD, resulting in a thermoresponsive nanotubular architecture. The inclusion complex was characterized using various techniques, and the formation of nanotubes was observed. The reversible switching of assembly and disassembly of the system was demonstrated by temperature changes. Hydrophobic interactions were identified as the main driving force behind the hierarchical structure formation, as confirmed by control experiments. Molecular dynamics simulations further elucidated the stepwise formation process of this hierarchy. This stimuli-responsive system has the potential to tailor its physical properties and contribute to the fabrication of novel smart materials.
