Microalga–microbiome interactions are central to both health and disease of aquatic environments. Despite impressive advances in deciphering how microorganisms participate in and impact aquatic ecosystems, the evolution and ecological involvement of microalgae and the microbiome in polluted waters are typically studied independently. Here, the phycosphere (i.e., the consortia of microalgae and the related microbiome) is regarded as an independent and integrated life form, and we summarize the survival strategies exhibited by this symbiont when exposed to anthropogenic pollution. We highlight the cellular strategies and discuss the modulation at the transcriptional and population levels, which reciprocally alters community structure or genome composition for medium-term acclimation or long-term adaptation. We propose a ‘PollutantBiome’ concept to help the understanding of microalga–microbiome interactions and development of beneficial microbial synthetic communities for pollutant remediation.

Structures with dynamic stress buffering effects have shown great potential for developing durable electrode materials. In this work, a dynamic self-adapting strategy is proposed to in situ construct durable (Bi, Sb)/dipotassium terephthalate (K 2 TP) from Bi 0.17 Sb 0.83 -MOF for the anode of potassium ion batteries (PIBs). K 2 TP, with a flexible structure, tightly incorporates particles of Bi 0.17 Sb 0.83 to form a new composite and buffers the stress caused by the repeated intercalation/de-intercalation of K ions. Benefiting from the novel structural and compositional superiorities, the Bi 0.17 Sb 0.83 -MOF@MXene exhibits an ultralong cyclability with negligible capacity decay at 200 mA g −1 after 900 cycles. This study not only illustrates the effectiveness of a dynamic self-adapting strategy but also provides a guiding insight for developing durable rechargeable batteries.

Ideal percutaneous titanium implants request both antibacterial ability and soft tissue compatibility. ZnO structure constructed on titanium has been widely proved to be helpful to combat pathogen contamination, but the biosafety of ZnO is always questioned. How to maintain the remarkable antibacterial ability of ZnO and efficiently reduce the corresponding toxicity is still challenging. Herein, a hybrid hydrogel coating was constructed on the fabricated ZnO structure of titanium, and the coating was proved to be enzymatically-degradable when bacteria exist. Then the antibacterial activity of ZnO was presented. When under the normal condition (no bacteria), the hydrogel coating was stable and tightly adhered to titanium. The toxicity of ZnO was reduced, and the viability of fibroblasts was largely improved. More importantly, the hydrogel coating provided a good buffer zone for cell ingrowth and soft tissue integration. The curbed Zn ion release was also proved to be useful to regulate fibroblast responses such as the expression of CTGF and COL-I. These results were also validated by in vivo studies. Therefore, this study proposed a valid self-adaptive strategy for ZnO improvement. Under different conditions, the sample could present different functions, and both the antibacterial ability and soft tissue compatibility were finely preserved.

In the present work, highly efficient catalytic adsorbents for Hg 0 removal in both oxygen-rich and deficient atmosphere are developed based on an “adaption” strategy. Firstly, a series of simplified SiO 2 -based catalytic adsorbents are prepared as model catalysts to gain a deeper insight into the mechanism of the catalytic Hg 0 removal process. It is found that for the effective Hg 0 removal, the catalytic adsorbent should possess an “assembling” structure involving both Hg 0 and oxygen activation sites. An “adaption” strategy is thus implemented for the devise of the catalytic adsorbent, including the functional adaption of different active sites for the reactants and the synergistic function of different active sites. Accordingly, high-efficiency catalytic adsorbent with strong redox property is developed for oxygen-rich atmosphere, while the catalytic adsorbent with high oxygen storage/release property is developed for oxygen-deficient conditions. Moreover, regeneration investigation indicates that the activities of spent catalytic adsorbents are almost fully recovered through the temperature programmed decomposition and desorption (TPDD) process. It is believed that the present “adaption” strategy for catalyst design has guiding significance for the rational and controllable construction of catalysts for other catalytic processes.
