In Situ MXene Anchored Structure for Highly Durable Solar Steam Generation

As a promising fresh water harvesting technology, interfacial solar steam generation has attracted growing interest. Efficient solar absorption and long-term operational performance are critical requirements of this technology. However, developing robust evaporators to promote practical applications under extreme conditions is still a grand challenge. Herein, we propose a light-assisted strategy to in situ prepare a Ti3C2Tx MXene anchored structure (MXAS) for enhanced solar evaporation with superior mechanical properties (compressive strength of 78.47 MPa, which can withstand a pressure of 3.92 × 106 times its own weight). Light irradiation enlarges the interlayer spacing of MXene and improves the solar absorption capability. Under one sun, the three-dimensional MXAS evaporator exhibits a steam generation rate of 2.48 kg m–2 h–1and an evaporation efficiency of 89.3%, and it demonstrates long-term durability when testing in seawater. This strategy provides valuable insights into the potential application of a high-performance water evaporation system

Solar-Driven Interfacial Evaporator with a Self-Powered Detector Based on the Gr@Ti₄O₇:Eu³⁺,Yb³⁺ Fibrous Membrane

Interfacial evaporation is energy-efficient to alleviate the freshwater issues by utilizing the renewable and inexhaustible solar energy. Herein, a fibrous photothermal membrane of Gr@Ti4O7 doped with Yb3+ and Eu3+ was prepared by electrospinning, which presented high photothermal conversion efficiency (96.01%), an outstanding evaporation rate (1.82 kg·m–2·h–1), and a remarkable salt rejection rate (99.997%). These results demonstrated that the combination of Ti4O7, graphene, and rare earth elements achieved photothermal synergy and surpassed a majority of photothermal materials constructed by semiconductors. In addition, based on the biomimetic concept of unidirectional water transfer through trees, a self-monitoring function was achieved using asymmetric hydrophobic modification and an electrical signal of 802 mV was obtained. This work not merely provided valuable prospects for its application in seawater desalination but also discovered a new function for self-monitoring of the evaporation process

<i>CF</i>_<i>2</i><i>–II</i> Alternative Splicing Isoform Regulates the Expression of Xenobiotic Tolerance-Related Cytochrome P450 <i>CYP6CY22</i> in <i>Aphis gossypii</i> Glover

The expression of P450 genes is regulated by trans-regulatory factors or cis-regulatory elements and influences how endogenous or xenobiotic substances are metabolized in an organism’s tissues. In this study, we showed that overexpression of the cytochrome P450 gene, CYP6CY22, led to resistance to cyantraniliprole in Aphis gossypii. The expression of CYP6CY22 increased in the midgut and remaining carcass of the CyR strain, and after repressing the expression of CYP6CY22, the mortality of cotton aphids increased 2.08-fold after exposure to cyantraniliprole. Drosophila ectopically expressing CYP6CY22 exhibited tolerance to cyantraniliprole and cross-tolerance to xanthotoxin, quercetin, 2-tridecanone, tannic acid, and nicotine. Moreover, transcription factor CF2–II (XM_027994540.2) is transcribed only as the splicing variant isoform CF2–II-AS, which was found to be 504 nucleotides shorter than CF2–II in A. gossypii. RNAi and yeast one-hybrid (Y1H) results indicated that CF2–II-AS positively regulates CYP6CY22 and binds to cis-acting element p (−851/-842) of CYP6CY22 to regulate its overexpression. The above results indicated that CYP6CY22 was regulated by the splicing isoform CF2-II-AS, which will help us further understand the mechanism of transcriptional adaption of cross-tolerance between synthetic insecticides and plant secondary metabolites mediated by P450s
