Summary: In this study, we explore non-trivial spin textures and nanoscale magnetic skyrmions and skyrmioniums in two-dimensional Janus magnets, such as MnSTe and MnSeTe. Using the micromagnetism approach and Landau-Lifshitz-Gilbert equation, we find that these Janus magnetic structures can host stable Neel nano-skyrmions with sub-10 nm diameters and skyrmioniums with zero topological charge. The size and topological charge of the skyrmions can be controlled by external magnetic fields.

Summary: This study successfully developed quaternary nanocomposites with exceptionally high toughness and hardness by constructing hierarchical structures spanning several scales. A new concept of multi-stage toughening mechanism was proposed, including laminated structure toughening, two-dimensional graphene toughening, and multi-component nanoparticles toughening. This low-cost toughening mechanism constitutes an important step forward in developing advanced ceramic matrix composites with high toughness and hardness.

Summary: Microfluidic technology provides a valuable tool for creating in vitro models that capture cellular and organ level responses for rapid and animal-free risk assessment of new chemicals and drugs. These cell-based devices allow high-throughput screening and flexible automation, reducing costs and reagent consumption due to miniaturization. The interconnected modules aim to simulate whole-body exposure and response, contributing to the replacement of animal testing in risk assessment studies in compliance with the 3Rs principles.

Summary: This study investigates the effects of three common nano materials on Portland cement paste at small dosages and optimizes the dosage using response surface methodology. The results show that adding nano materials can greatly promote the hydration and improve the compressive strength of Portland cement at early ages. Moreover, combining nano-SiO2, nanoTiO2, and nano-CaCO3 together can further enhance the hydration promotion effect and compressive strength of Portland cement.

Summary: Evaporation is a significant physical phenomenon with fundamental importance in both nature and technology. Theoretical models for describing evaporation kinetics at nano and sub-nanometer scales are lacking, but are crucial for the development of nano-scale devices. Understanding the physics of evaporation in nano/molecular materials is essential for explaining related phenomena and developing appropriate models.

Summary: The interaction between nano-cell and nano-pollutant plays a crucial role in determining the combined cytotoxicity of nanoparticles and pollutants. The impact of CNPs and ZnONPs on Cr(VI) differs, with CNPs reducing the cytotoxicity of CNP-Cr(VI) adducts while ZnONPs enhancing the cytotoxicity of ZnONP-Cr(VI) adducts. In-depth investigations on the interaction mechanisms are essential for a comprehensive understanding of the combined cytotoxicity of different NPs and pollutants.

Summary: The tetra-armed cyclen compound bearing specific groups was prepared and characterized along with its Ag+ complexes. These complexes were found to undergo reversible structural transformations between different ratios of Ag+ / 1, and could selectively encapsulate benzene and [D6]benzene in the solid-state. The stability of the benzene-included structures was attributed to C-H···F-C interactions between the benzene molecule and the ligand molecule.

Summary: Controllable nano-assembly with stimuli-responsive groups is a powerful strategy for generating theranostic nanosystems in modern medicine. However, the understanding of complex interactions between nanoassemblies and biosystems is still lacking, which limits the development of this field. In this review, the authors propose a 4W1H principle to describe the dynamic biological processes, behavior, and fate of nano-assemblies, and summarize key parameters that govern effective nano-bio interactions. The effects of these parameters on ADMET processes are discussed, and challenges in evaluating nano-bio interactions of assembled nanodrugs are highlighted.
