Summary: The dynamic magnetization responses of magnetic nanoparticles (MNPs) in alternating magnetic fields are important for biomedical applications. Multiple factors, including Brownian and Néel relaxations and extrinsic/intrinsic factors, can influence the dynamic magnetization responses. However, understanding the effects of each factor can be challenging due to the complexity of energy terms and interparticle interactions involved.

Summary: We present a unique method to synthesize patchy nanoparticles by controlling the orientation of the molecules through synchronous polymerization and crystallization. The resulting nanoparticles have uniform shapes and a single liquid crystal domain. The patchy properties can be activated or deactivated by solvents, and additional colloidal blocks can be added to create triblock patchy dumbbells with integrated optical properties. These nanoparticles demonstrate triple-mode optical authentication and can be used in anti-counterfeiting labels or patterns. Furthermore, the patchy cylinders can serve as building blocks for long liquid crystal rods or porous colloidal materials.

Summary: The study investigates the viscoelastic properties of two semiconductor nanoparticles CdS@GSH and PbS@GSH in hydrogel systems. The results show that CdS@GSH exhibits stronger viscoelastic properties compared to PbS@GSH, with smaller nanoparticles forming stiffer hydrogels. The PbS@GSH hydrogel system is influenced by changes in nanoparticle concentrations and pH value, with higher water proportion leading to greater mechanical properties and higher alkalinity resulting in increased hardness and storage modulus. Increasing the pH value of the PbS@GSH hydrogel system enhances viscoelastic properties by dissociating surface GSH molecules to form Pb2+ and GSH complexes.

Summary: Our experiments demonstrated that highly polarized Ni-Fe-O materials can be influenced by polar gases, resulting in changes to their magnetic properties. Adsorbed gas molecules altered the material's magnetic properties through weak electronic interactions at the metal atom-gas molecule interface. Coercivity and blocking temperature of the material exhibited opposite changes for different gases due to variations in their electron affinities. Density Functional Theory calculations confirmed that gas adsorption induced alterations in the electric field and spin-charge distribution, leading to shifts in the Fermi level and movement of top atomic layers. These shifts ultimately affected the material's magnetic anisotropy. Importantly, these changes were reversible upon desorption of the gas, facilitated by molecular attraction between the gas and material. Overall, our experimental and theoretical findings enhance the understanding of polar gas interactions with magnetic material surfaces.

Summary: The hierarchical self-assembly process has great potential for constructing nanostructural superlattices, but precise regulation remains a challenge. This study introduces the concept of unimolecular nanoparticles (UMNPs) that act as supramolecular motifs and directly assemble into superlattices. The discovery of complex phases and support for the previously proposed self-sorting process are provided by blending UMNP with conventional giant molecules.

Summary: The study reveals that nanoparticle-mineral interactions can switch from compositionally repulsive to adhesive with decreasing coating densities of bicomponent polyol-fluoroalkane self-assembled monolayers on calcite surfaces. This transition is attributed to the collapse of fluoroalkanes into the voids of SAMs, where they lose the ability to perturb hydration layers on calcite surfaces.

Summary: Metal-organic frameworks based on tetrahedral pyridyl ligands can form a series of isostructural crystals with different metal ions and properties. By conducting cation exchanges, an iterative crystal-to-crystal conversion can be achieved, which is influenced by the stability of the resulting coordination nodes. The optical and magnetic properties of the crystals are controlled by the metal cation, and the crystals preserve their morphology, enabling quantitative comparison of their properties at both the ensemble and single-crystal level.

Summary: Based on experimental and computational analysis, the relationship between solid-state supramolecular interactions and crystal habits is discussed in the context of strong halogen-bonded associations. The energy frameworks and attractive/repulsive interactions of these associations directly correlate with their crystal habits. This correlation suggests that analyzing the energy framework can help rationalize and predict crystal habits.
