Summary: Large-scale nanoalloys of Co-Pt ranging from 3 to 7 nm in size were modeled using realistic atomistic potentials and Monte Carlo simulations, showing a tendency to reproduce bulk-ordered phases and structures on the surfaces. Certain surface structures were found to be incompatible with the core structure, resulting in disorder underneath. Mixed compositions were predicted on some surfaces, indicating a frustration in chemical ordering in nanoalloys.

Summary: In this work, a database of atomic strain distributions for AgPd nanoalloys is established. The presence of compressive strain at the edges and corners and compressive strain exerted on the surface of Ag@Pd nanoalloys, particularly the one with an icosahedral shape, is found to boost the catalytic activity for formate dehydrogenation and oxidation reactions. This study provides a theoretical perspective on the development and use of formate as a hydrogen carrier and fuel.

Summary: The interaction between plasmons and electronic or spin states in nanostructures is a fascinating topic in the fields of photonics, optoelectronics, and spintronics. This study investigates the magneto-optical properties of plasmonic InN and Cu2-xSe nanocrystals and finds that complete exciton polarization induced by cyclotron motion of free carriers is a universal phenomenon in semiconductor nanocrystals. The selective exciton polarization can be controlled by carrier type, mass, and velocity, leading to the manipulation of quantum states for spintronic and optoelectronic applications.

Summary: The development of skyrmionic devices requires tuning material parameters to stabilize and control the density of skyrmions. Recent research has shown that different types of skyrmions can be simultaneously stabilized at room temperature in heterostructures containing ferromagnets, ferrimagnets, and heavy metals, offering a new platform for encoding binary information using skyrmion types instead of their presence or absence. By adjusting the geometric and material parameters of individual layers, the energy landscape of the two skyrmion types in such heterostructures can be finely tuned.

Summary: Fe20:Ag80, Fe50:Ag50, and Fe80:Ag20 bimetallic nanoparticles were prepared using laser ablation method on Fe/Ag/polyvinyl alcohol (PVA) composite. The ratio of Fe to Ag atoms and the ablation time affected the wavelength, intensity, and width of the plasmon absorption peak. An increase in Fe content resulted in a redshift and a decrease in intensity, as well as an increase in the width of the plasmon absorption peaks. Transmission electron microscopy (TEM) analysis revealed three types of particles: Ag nanoparticles, Ag/Fe core/shells, and Fe nanoparticles. The formation of a core-shell structure between Fe and Ag caused a decrease in Ag plasmon resonance frequency and a redshift in its absorption peak. Vibrating sample magnetometer (VSM) measurements showed that the Fe/Ag bimetallic nanoparticles exhibited superparamagnetic properties.

Summary: We synthesized aggregation-induced emission (AIE) polymers with unchanged emission wavelength/color through ring-opening (co)polymerizations. The chemical structures/physical properties of the (co)polymers were characterized by NMR, SEC, MALDI-TOF, and DSC. The co-polyether microstructures were studied by calculating reactivity ratios and visualized by Monte Carlo simulation. The fluorescence performance was systematically correlated with molecular weights, crystallinity, monomer compositions, glass transition temperatures, side lengths, and flexibility/rigidity.

Summary: Zero-dimensional (0D) scintillation materials are of great interest for the fabrication of flexible high-energy radiation scintillation screens. Challenges still persist in the development of 0D scintillators, but a strategy based on metal nanoclusters shows promise in overcoming these limitations. This work demonstrates the synthesis and self-assembly of atomically precise nanoclusters with high phosphorescence quantum yield, AIEE behavior, and intense radioluminescence. The self-assembled nanoclusters can be used as building blocks for flexible particle-deposited scintillation films with high-resolution X-ray imaging performance.

Summary: Inorganic halide perovskite nanocrystals (NCs) are extensively studied as next-generation optoelectronic materials. The atomic structure at the surface of CsPbBr3 NCs is directly observed, revealing a Cs-Br terminated surface with a significantly decreased Cs-Cs bond length, inducing compressive strain and polarization. Density functional theory calculations suggest that this reconstructed surface contributes to the separation of holes and electrons. These findings enhance our understanding of the surface structure and provide insights for designing stable and efficient optoelectronic devices.

Summary: We investigated the effect of different organic coatings on the H-1-NMR relaxation properties of ultra-small iron-oxide-based magnetic nanoparticles. Magnetization measurements revealed similar behavior as a function of temperature and field for nanoparticles with different coatings but the same core diameter. However, the H-1-NMR longitudinal relaxivity showed different intensity and frequency behavior for the smallest particles depending on the kind of coating, indicating different electronic spin dynamics. On the other hand, no differences were found in the relaxivity of the biggest particles when the coating was changed.

Summary: In this perspective article, we review the most significant case studies on magnetic nanoparticles for potential applications in nanomedicine, especially in magnetic resonance imaging. The dependence of the relaxation behavior of magnetic nanoparticles on their chemico-physical properties is discussed in detail. The correlations between the efficiency of magnetic nanoparticles as contrast agents in magnetic resonance imaging and their magnetic core (mainly iron oxides), size and shape, and the coating and solvent used for biocompatibility and dispersibility in physiological media are critically reviewed. Finally, the heuristic model proposed by Roch and coworkers is presented, and its advantages and limitations are highlighted through the analysis of a large amount of experimental data.
