| 1 | Fabrication of PVDF nanofibrous hydrophobic composite membranes reinforced with fabric substrates via electrospinning for membrane distillation desalination显示文摘To improve the mechanical properties of the electrospun nanofibrous membrane, the nonwoven fabrics and spacer fabrics were employed as support substrates to fabricate polyvinylidene fluoride(PVDF) nanofibrous composite membranes. The influences of the substrate on membrane morphology, hydrophobicity, pore size and pore size distribution,porosity, mechanical strength and permeability were comprehensive evaluated. The electrospun composite membranes had a three dimension bead-fiber interconnected open structure and a rough membrane surface. The membrane surface presented a multilevel re-entrant structure and all the water contact angles were above 140°. In contrast with the pure PVDF nanofibrous membrane, the stress at break and the elastic modulus of the composite membranes increased by 4.5–16 times and 17.5–37 times, respectively. Since the spacer fabrics had less resistance to mass transfer, the membranes composited with spacer fabrics exhibited greater permeate fluxes compared with the composite membranes with the nonwoven fabrics as substrates.During the membrane distillation test, the highest permeate flux was up to 49.3 kg/m^2/hr at the feed temperature of 80°C. The long-time and repeat operation of membrane distillation desalination indicated the fabricated membrane with a good resistance to scaling and wetting.The results suggested the potential of the electrospun composite membrane for membrane distillation application. | Kuiling Li Deyin Hou Chaochen Fu Kai Wang Jun Wang | 2019 | Journal of Environmental Sciences2019，31，1： | 4 |

| 3 | A novel electro-Fenton hybrid system for enhancing the interception of volatile organic compounds in membrane distillation desalination显示文摘Membrane distillation(MD)is a promising alternative desalination technology,but the hydrophobic membrane cannot intercept volatile organic compounds(VOCs),resulting in aggravation in the quality of permeate.In term of this,electro-Fenton(EF)was coupled with sweeping gas membrane distillation(SGMD)in a more efficient way to construct an advanced oxidation barrier at the gas-liquid interface,so that the VOCs could be trapped in this layer to guarantee the water quality of the distillate.During the so-called EF-MD process,an interfacial interception barrier containing hydroxyl radical formed on the hydrophobic membrane surface.It contributed to the high phenol rejection of 90.2% with the permeate phenol concentration lower than 1.50 mg/L.Effective interceptions can be achieved in a wide temperature range,even though the permeate flux of phenol was also intensified.The EF-MD system was robust to high salinity and could electrochemically regenerate ferrous ions,which endowed the long-term stability of the system.This novel EF-MD configuration proposed a valuable strategy to intercept VOCs in MD and will broaden the application of MD in hypersaline wastewater treatment. | Hongxin Liu Kuiling Li Kunpeng Wang Zhiyong Wang Zimou Liu Sichao Zhu Dan Qu Yu Zhang Jun Wang | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
| 4 | Styrax japonicus functional genomics:an efficient virus induced gene silencing(VIGS)system显示文摘VIGS(Virus-induced gene silencing),a method for posttranscriptional gene silencing,is an effective technique for investigating the activities of genes in plants.Since there is no report for available VIGS system in Styrax japonicus,the application of a VIGS approach that results in a gene knockdown to study gene function is limited.In this study,we compared the characteristics that could affect the viability of VIGS in S.japonicus,including the acetosyringone(AS)concentration,the Agrobacterium’s optical density and the inoculation method.The stable reference genes of S.japonicus were selected to validate the gene’s knockdown by quantitative PCR.As a result,we successfully constructed 2 VIGS systems based on TRV virus:vacuum with AS concentration of 200μmol·L^(-1)and OD600of 0.5,and friction-osmosis with AS concentration of 200μmol·L^(-1)and OD600of 1.0,which silencing efficiency was 83.33%and 74.19%,respectively.The successfully applied VIGS method provides a rapid and effective reverse gene functional analysis approach in S.japonicus to identify unknown gene functions. | Gangyu Sun Yiqian Ju Cuiping Zhang Lulu Li Xinqiang Jiang Xiaoman Xie Yizeng Lu Kuiling Wang Wei Li | 2024 | Horticultural Plant Journal2024，10，1： | 0 |
| 5 | Global multifaceted biodiversity patterns,centers,and conservation needs in angiosperms显示文摘The Convention on Biological Diversity seeks to conserve at least 30%of global land and water areas by 2030,which is a challenge but also an opportunity to better preserve biodiversity,including flowering plants(angiosperms).Herein,we compiled a large database on distributions of over 300,000 angiosperm species and the key functional traits of 67,024 species.Using this database,we constructed biodiversity-environment models to predict global patterns of taxonomic,phylogenetic,and functional diversity in terrestrial angiosperms and provide a comprehensive mapping of the three diversity facets.We further evaluated the current protection status of the biodiversity centers of these diversity facets.Our results showed that geographical patterns of the three facets of plant diversity exhibited substantial spatial mismatches and nonoverlapping conservation priorities.Idiosyncratic centers of functional diversity,particularly of herbaceous species,were primarily distributed in temperate regions and under weaker protection compared with other biodiversity centers of taxonomic and phylogenetic facets.Our global assessment of multifaceted biodiversity patterns and centers highlights the insufficiency and unbalanced conservation among the three diversity facets and the two growth forms(woody vs.herbaceous),thus providing directions for guiding the future conservation of global plant diversity. | Ao Luo Yaoqi Li Nawal Shrestha Xiaoting Xu Xiangyan Su Yichao Li Tong Lyu Kilara Waris Zhiyao Tang Xiaojuan Liu Luxiang Lin Yongsheng Chen Kuiling Zu Wenqi Song Shijia Peng Niklaus E.Zimmermann Loïc Pellissier Zhiheng Wang | 2024 | Science China(Life Sciences)2024，67，4： | 0 |
