“…After exploring the nanospikes-mediated anomalous dispersity on larger particles, whether this phenomenon was applicable to different core particle materials or different nanospike materials were investigated. TiO 2 nano/micro-particles are one of the most promising materials that can be applied as photocatalysts 25 , 26 , drug carriers 27 – 29 , or components for cosmetics 30 , 31 , or sunscreens 32 – 34 . In this regard, 2 μm TiO 2 microparticles were functionalized with ZnO nanospikes and then hydrophobically conjugated with PFES (TiO 2 ^2 μm Spiky-F).…”

Many fields of applications require dispersion of hydrophobic particles in water, which is traditionally achieved by using surfactants or amphiphilic molecules to modify particle surfaces. However, surfactants or amphiphilic molecules may disturb the native solution or particles’ surface hydrophobicity, limiting extended applications such as oil emulsion cleaning. Recently one example of 2 μm-size polystyrene microparticles covered with ZnO nanospikes has been shown to exhibit excellent dispersity in water in spite of surface hydrophobicity. Whether this anomalous dispersion phenomenon was applicable to other hydrophobic microparticle systems was still unclear and its application scope was limited. Here the anomalous dispersities of different hydrophobic spiky micro-objects were systematically explored. The results show that the anomalous dispersion phenomenon was universally observed on different hydrophobic spiky micro-objects including different hydrophobic coating, particle sizes, material compositions and core particle morphologies. In addition, the spiky micro-objects displayed anomalous dispersity in water without compromising surface hydrophobicity, and their applications for oil spills absorption and oil emulsion cleaning were demonstrated. This work offers unique insight on the nanospikes-mediated anomalous dispersion phenomenon of hydrophobic micro-object and potentially extends its applicability and application scopes.

“…Brookite has rarely been used or studied thus far, due to its scarcity in the environment (Allen et al, 2010) and difficulties in preparing significant amounts of good quality material (Gong and Selloni, 2007). Both rutile and anatase forms are widely employed in consumer products like toothpaste, sunscreens, food, paints, plastics, paper, and biomedical devices (Wang et al, 2007;Middlemas et al, 2013;de la Calle et al, 2017;Barbosa et al, 2018;Leong and Oh, 2018;Dorier et al, 2019). Furthermore, they are also used in environmental oriented applications including wastewater treatment (Yuzer et al, 2015), air purification (Paz, 2010) and soil remediation (Yang and Xing, 2009).…”

Metal-based nanoparticles (NPs) are the most widely used engineered nanomaterials. The individual toxicities of metal-based NPs have been plentifully studied. However, the mixture toxicity of multiple NP systems (n ≥ 3) remains much less understood. Herein, the toxicity of titanium dioxide (TiO2) nanoparticles (NPs), silicon dioxide (SiO2) NPs and zirconium dioxide (ZrO2) NPs to unicellular freshwater algae Scenedesmus obliquus was investigated individually and in binary and ternary combination. Results show that the ternary combination systems of TiO2, SiO2 and ZrO2 NPs at a mixture concentration of 1 mg/L significantly enhanced mitochondrial membrane potential and intracellular reactive oxygen species level in the algae. Moreover, the ternary NP systems remarkably increased the activity of the antioxidant defense enzymes superoxide dismutase and catalase, together with an increase in lipid peroxidation products and small molecule metabolites. Furthermore, the observation of superficial structures of S. obliquus revealed obvious oxidative damage induced by the ternary mixtures. Taken together, the ternary NP systems exerted more severe oxidative stress in the algae than the individual and the binary NP systems. Thus, our findings highlight the importance of the assessment of the synergistic toxicity of multi-nanomaterial systems.
