| 1 | A facile method to fabricate surfaces showing superhydrophilicity in air and superhydrophobicity in oil显示文摘The changes of the wettability of the solid surfaces have attracted massive attention due to their important practical implications in numerous fields. As a new subject, the research on the wettability under the different environments is still in its early stage. So the fundamental research must be performed for the practical applications under different environments. However, it is seldom that the comprehensive wettability of a surface in air, in water and in oil has been reported. In this paper, the authors investigated the wettability of the stainless steel mesh coated with polyurethane in the above three different environments. The surface of the uncoated mesh was found to be hydrophobic in air, but the surface of the coated mesh was superhydrophilic in air. More interestingly, the surfaces of the coated meshes were superoleophilic in water and superhydrophobic in oil. Due to the coated meshes with these wettabilities were fabricated via a facile two-step method, the presented method may be adopted for large-scale industrial production, in various fields, such as icing prevention or the oil-field industry. | YE XiangDong GUO YuXuan JIA YanChao YE Xin WANG Shuai CAI AnJiang WU XiaoJun SHAO JinYou | 2017 | Science China(Technological Sciences)2017，60，11： | 2 |
| 2 | A CCCH zinc finger gene regulates doublesex alternative splicing and male development in Bombyx mori显示文摘Recent identification of a Piwi-interacting RNA(piRNA)-initiated sex determination cascade in the silkworm,Bombyx mori,provides novel insights into high diversity of insect sex determination pathways.In this system,the W-chromosome-derived Fem piRNA is the primary sex determination signal.A CCCH-type zinc finger gene Masculinizer(Masc),which is targeted by Fem piRNA-PIWI complex in female animals,is indispensable for male-specific splicing of B.mori doublesex(Bmdsx).Although many genes involved in this cascade have been identified,the regulatory mechanisms of silk-worm sex determination remain to be elucidated.Here we show that another CCCH-type zinc finger gene,Bmznf-2,is a masculinization factor in B.mori.Bmznf-2 shows testisabundant expression and loss of Bmznf-2 function via clustered regularly interspaced short palindromic repeats 1 single-guide RNA-mediated mutagenesis results in feminized differentiation and appearance of the female-specific splicing variants of Bmdsx transcripts in males.In contrast,there is no phenotypic consequence in mutant females.In mutant males,relative messenger RNA expression levels of female-dominant genes such as vitellogenin and sex-specific storage protein I are significantly clevated while several male-dominant genes are significantly down-regulated.Furthermore,male mutants show delayed developmental timing,smaller body sizes of larvae and malformation of moth wings.Our data thus reveal that Bmznf-2 plays an indispensable role in silkworm male sexual differentiation. | Fangying Yang Zhongjie Zhang Bo Hu Ye Yu Anjiang Tan | 2021 | Insect Science2021，28，5： | 1 |
| 3 | Two dehydroecdysone reductases act as fat body-specific 20E catalyzers in Bombyx mori显示文摘Periodic post-embryonic changes in insects, including growth, development and metamorphosis, are strictly controlled by many compounds, including steroid hormones. The biosynthesis and clearance of 20-hydroxyecdysone (20E), the major active form of the insect steroid hormone ecdysone, result in titer fluctuations that help control insect development. The inactivation of 20E in the silkworm Bombyx mori is highly tissue-specific, with CYP18A1 and ecdysone oxidase controlling 20E inactivation specifically in the mid-silk gland and midgut, respectively. Here, we characterized silkworm 3-dehydroecdysone 3α reductase (Bm3DE3α) and 3-dehydroecdysone 3β reductase (Bm3DE3β), two enzymes involved predominantly in the C-3-mediated catalysis of 20E in fat bodies. The ubiquitous and silk gland-specific overexpression of Bm3DE3α decreased the 20E titer, resulting in larval lethality and larval–pupal transition failure, respectively. In contrast, the ubiquitous and mid-silk gland-specific overexpression of Bm3DE3β increased the 20E titer, resulting in larval growth delays and lethality at the mid-fifth larval stage, respectively. Thus, Bm3DE3α and Bm3DE3β mediate fat body-specific steroid hormone metabolism in B. mori, indicating that highly diversified 20E metabolism-related mechanisms exist in different insect species. | Lang You Zhiqian Li Zhongjie Zhang Bo Hu Ye Yu Fangying Yang Anjiang Tan | 2022 | Insect Science2022，29，1： | 1 |

| 5 | Revisiting the ionic diffusion mechanism in Li_(3)PS_(4) via the joint usage of geometrical analysis and bond valence method显示文摘Inorganic solid electrolytes have obvious advantages on safety and electrochemical stability compared to organic liquid electrolytes,but the advance on high ionic conductivity of typical electrolytes is still undergoing.Although the first-principles calculation in the ion migration simulation is an important strategy to develop high-performance solid electrolyte,the process is very time-consuming.Here,we propose an effective method by combining the geometrical analysis and bond valance sum calculation to obtain an approximate minimum energy path preliminarily,in parallel to pave the way for the interoperability of low-precision and high-precision ion transport calculation.Taking a promising electrolyte Li_(3)PS_(4) as an example,we revisit its Li-ionic transport behavior.Our calculated Li-ion pathways and the activation energies(the corresponding values:1.09 eV vs.0.88 eV vs.0.86 eV)in γ-,β- and α-Li_(3)PS_(4) are consistent with the ones obtained from the first-principles calculations.The variations of the position of P-ions lead the rearrangement of the host PS_(4) tetrahedron,affecting the diffusion positions of Li-ions and further enabling high Li^(+) conductivity in β-Li_(3)PS_(4). | Li Pan Liwen Zhang Anjiang Ye Shuting Chi Zheyi Zou Bing He Lanli Chen Qian Zhao Da Wang Siqi Shi | 2019 | Journal of Materiomics2019，5，4： | 0 |
