Abstract:
... Manufacturing heterostructure architectures with multiple interfaces and understanding the interfacial polarizations are important for exploring high-efficient microwave absorbents. Herein, high-crystalline core-shell FeCo@Fe₃O₄ nanoparticles were in-situ anchored on graphene. The FeCo@Fe₃O₄/graphene hybrids reveal boosting microwave absorption which can be adjusted by controlling the graphene com ...

Abstract:
... For most passive sampling applications, the availability of accurate passive sampler–water partition coefficients (Kₚ‐w) is of key importance. Unfortunately, a huge variability exists in literature Kₚ‐w values, in particular for hydrophobic chemicals such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). This variability is a major source of concern in the passive sa ...

Abstract:
... Fullerene C₆₀ is an all-carbon cage molecule with rich physicochemical properties. It is highly symmetric and hydrophobic, which can be used as a building block for the preparation of amphiphiles that self-assemble into diverse supramolecular structures in aqueous solutions. Meanwhile, C₆₀ is also lipophobic, which is different from the alkyl chains in traditional surfactants. By attaching alkyl c ...

Abstract:
... Hydrocarbons are well-known insoluble oils which are rarely considered as stimuli to trigger molecular self-assembly transition. We report in this work that hydrocarbons are a class of distinct stimuli for the self-assembly transition in the catanionic surfactant systems. Particularly, the cyclic hydrocarbons and chain-like ones has exactly opposite impact. By solubilizing in the palisade region o ...

So far, various biological models for the high water repellency have been reported, which, however, focused mostly on the structural topology with less attention on the dimension character. Here, we revealed a common dimension charac ...
