1Antimony(V) removal from water by hydrated ferric oxides supported by calcite sand and polymeric anion exchanger显示文摘We fabricated and characterized two hybrid adsorbents originated from hydrated ferric oxides(HFOs) using a polymeric anion exchanger D201 and calcite as host. The resultant adsorbents(denoted as HFO-201 and IOCCS) were employed for Sb(V) removal from water. Increasing solution pH from 3 to 9 apparently weakened Sb(V) removal by both composites, while increasing temperature from 293 to 313 K only improved Sb(V) uptake by IOCCS. HFO-201 exhibited much higher capacity for Sb(V) than for IOCCS in the absence of other anions in solution. Increasing ionic strength from 0.01 to 0.1 mol/L NaNO3would result in a significant drop of the capacity of HFO-201 in the studied pH ranges; however, negligible effect was observed for IOCCS under similar conditions. Similarly, the competing chloride and sulfate pose more negative effect on Sb(V) adsorption by HFO-201 than by IOCCS, and the presence of silicate greatly decreased their adsorption simultaneously, while calcium ions were found to promote the adsorption of both adsorbents. XPS analysis further demonstrated that preferable Sb(V) adsorption by both hybrids was attributed to the inner sphere complexation of Sb(V) and HFO, and Ca(II) induced adsorption enhancement possibly resulted from the formation of HFO-Ca-Sb complexes. Column adsorption runs proved that Sb(V) in the synthetic water could be effectively removed from 30 μg/L to below 5 μg/L(the drinking water standard regulated by China), and the effective treatable volume of IOCCS was around 6 times as that of HFO-201, implying that HFO coatings onto calcite might be a more effective approach than immobilization inside D201.Yangyang Miao Feichao Han Bingcai Pan Yingjie Niu Guangze Nie Lu Lv 2014Journal of Environmental Sciences2014,26,2:20

3Formability,microstructure evolution and mechanical properties of wire arc additively manufactured AZ80M magnesium alloy using gas tungsten arc welding显示文摘Wire arc additive manufacturing(WAAM)technology has been used to fabricate the multi-layer single-pass deposited wall of AZ80M magnesium(Mg)alloy by gas tungsten arc welding.The formability,thermal cycles,microstructural evolution and mechanical properties of the WAAM AZ80M Mg alloy were investigated.The results show that there was significant difference in the temperature variation and the geometries between the original several layers and the subsequent deposited layers.Owing to the arc energy input,the interpass temperature rised rapidly and then stabilized at 150℃.As a result,the width of the deposited wall increased and then kept stable.There were obvious differences in the microstructure of the WAAM AZ80M Mg alloy among the top zone,intermediate zone and bottom zone of deposited wall.During the arc deposition process,theβphase of the WAAM AZ80M Mg alloy redissolved due to the cyclic heat accumulation,and then precipitated in the grain boundary.The cyclic heat accumulation also led to weakening of dendrite segregation.From the substrate to the top zone,the hardness of the deposited wall decreased gradually,and the intermediate zone which was the main body of deposited wall had relatively uniform hardness.The tensile properties of the WAAM AZ80M Mg alloy were different between the vertical direction and the horizontal direction.And the maximum ultimate tensile strength of the WAAM AZ80M Mg alloy was 308 MPa which was close to that of the as-extruded AZ80M Mg alloy.Yangyang Guo Gaofeng Quan Yinglong Jiang Lingbao Ren Lingling Fan Houhong Pan 2021Journal of Magnesium and Alloys2021,9,1:10
4In vitro degradation and biocompatibility evaluation of typical biodegradable metals (Mg/Zn/Fe) for the application of tracheobronchial stenosis显示文摘Tracheobronchial obstruction in children due to benign stenosis or tracheobronchomalacia still remains a challenging matter of concern.Currently,there is 10%–20%complication rate in clinical treatment.The nonbiodegradable property of silicone stents and nickel-titanium memory alloy stents take the primary responsibility for drawbacks including stimulating local granulation tissue proliferation,displacement,and stent-related infections.Permanent tracheobronchial stent will be a persistent foreign object for a long time,causing excessive secretion of tracheal mucosa,ulceration and even perforation,which is particularly unsuitable for young children with persistent tracheal growth.In this study,the degradation and biocompatibility performance of three typical biodegradable metals were investigated as potential tracheobronchial stent materials.The results exhibited that these materials showed different degradation behaviors in the simulating respiratory fluid environment compared with SBF.Except for pure iron group,high purity magnesium and zinc showed favorable cell adhesion and proliferation in three culture methodologies(direct culture,indirect culture and extraction culture).The proper corrosion rate and good biocompatibility indicated that high purity magnesium and zinc may be good candidates as tracheobronchial stent materials.Yangyang Li Jianglong Yan Wenhao Zhou Pan Xiong Pei Wang Wei Yuan Yufeng Zheng Yan Cheng 2019Bioactive Materials2019,4,1:8
5Effect of heat treatment on the microstructure and mechanical properties of AZ80M magnesium alloy fabricated by wire arc additive manufacturing显示文摘To maximize the benefits of wire arc additive manufacturing(WAAM)processes,the effect of post-deposition heat treatment on the microstructure and mechanical properties of WAAM AZ80M magnesium(Mg)alloy was investigated.Three different heat treatment procedures(T4,T5 and T6)were performed.According to the results,after T4 heat treatment,the microsegregation of alloying elements was improved with the eutectic structure dissolved.Samples after T5 heat treatment inherited the net-like distribution of secondary phases similar to the as-deposited sample,where the eutectic structure covering the interdendritic regions and theβ-phase precipitated around the eutectic structure.After T6 heat treatment,the tinyβ-phases re-precipitated from the matrix and distributed in inner and outer of the grains.The hardness distribution of the samples went through T4 and T6 heat treatment was more uniform in comparison to that of T5 heat treated samples.The tensile test showed that the T6 heat treatment improved the strength and ductility,and the anisotropy between horizontal and vertical can be eliminated.Moreover,T4 treated samples exhibited highest ductility.Yangyang Guo Gaofeng Quan Mert Celikin Lingbao Ren Yuhang Zhan Lingling Fan Houhong Pan 2022Journal of Magnesium and Alloys2022,10,7:5

10N^(6)-methyladenosine methyltransferase plays a role in hypoxic preconditioning partially through the interaction with lncRNA H19显示文摘N^(6)-methyladenosine(m6A),a m ethylation in the N6 position of adenosine especially in the mRNA,exerts diverse physiological and pathological functions.However,the precise role of m 6A methylation in hypoxic preconditioning(HPC)is still unknown.Here,we observed that HPC treatm ent protected H9c2 cells against H2O2-induced injury,upregulated the m 6A level in the total RNA and the expression of methyltransferase like 3(METTL3),methyltransferase like 14(METTL14),and long noncoding RNA(lncRNA)H19.Either knockdown of METTL3 or METTL14 notably reversed the HPC-induced enhancement of cell viability,anti-apoptosis ability,and H19 expression.M ethylated RNA im m unoprecipitation(IP)indicated that knockdown of METTL3 or METTL14 decreased m 6A level in the lncRNA H19.Gain-of-function assay dem onstrated that H19 overexpression could partially rescue the decreased protection mediated by METTL3 or METTL14 knockdown in HPCtreated H9c2 cells.RNA binding protein im m unoprecipitation(RIP)assay showed that METTL3 and METTL14 could directly bind w ith H19.Our study identified a novel pattern of posttranscriptional regulation in HPC treatm ent.Since METTL3,METTL14,and lncRNA H19 were involved in HPC protection,they could be considered as potential biomarkers and therapeutic targets in HPC-derived cardiac rehabilitation and therapeutic approaches.Yamin Su Rongfeng X u Rui Zhang Yangyang Qu Wenjie Zuo Zhenjun Ji Haihua Geng Min Pan Genshan Ma 2020Acta Biochimica et Biophysica Sinica2020,52,12:1

12The Chinese herbal formula Tongluo Jiunao promotes expression of brain-derived neurotrophic factor/tropomyosin-related kinase B pathways in a rat model of ischemic brain injury显示文摘The neurotrophin-Trk receptor pathway is an intrinsic pathway to relieve damage to the central nervous system. The present study observed the effects of Tongluo Jiunao (TLJN), which comprises Panax Notoginseng and Gardenia Jasminoides, on expression of brain-derived neurotrophic factor (BDNF) and tropomyosin-related kinase B (TrkB) in a rat model of focal cerebral ischemic injury. Xue Sai Tong (XST), comprising Panax Notoginseng, served as the positive control. Mechanisms of neuroprotection were analyzed following TLJN injection. Following establishment of the middle cerebral artery occlusion models, TLJN and XST were intraperitoneally injected, and 2, 3, 5-triphenyltetrazolium chloride staining results revealed that TLJN injection reduced infarct volume, suggesting that TLJN exerted a neuroprotective effect. Enzyme-linked immunosorbent assay results showed that TLJN elevated BDNF and growth associated protein-43 expression in ischemic brain tissues, as well as serum BDNF levels. Reverse-transcription polymerase chain reaction and western blot results showed that TLJN injection did not affect TrkB expression in the ischemic brain tissues of rats. These results suggested that TLJN injection reduced damage to ischemic brain tissues and increased BDNF expression. In addition, TLJN injection resulted in better promoting effects on neurotrophic factor expression compared with XST.Peiman Alesheikh Huiling Tang Pengtao Li Wei Zhang Yanshu Pan Arezou Mashoufi Liyun Zhao Runjun Wang Bo Di Yangyang Yan 2011Neural Regeneration Research2011,6,12:1
13Polyetheretherketone with citrate potentiated influx of copper boosts osteogenesis,angiogenesis,and bacteria-triggered antibacterial abilities显示文摘A well designed coating for polyetheretherketone(PEEK)implants can provide enough support to overcome crucial medical challenges,which are insufficient osseointegration and high rate of infection.Herein,we utilize the co-deposition of polydopamine(PDA)and copper-citrate nanoclusters to construct a p H-responsive coating on porous PEEK for synergistic bone regeneration,vascular formation and anti-infection.Specifically,this PDA coating released high dose of copper and citrate at lower p H value,which increased intracellular copper content,boosted production of reactive oxygen species and severe damage of protein,leading to killing of 93%planktonic bacterial and eradication of adherent bacteria.At p H of 7.4,the release of copper and citrate were in a slow and sustained behavior,synergistically enhanced vascular formation potential and osteodiffereration of Ad-MSC in vitro.After implanted in rabbit tibia for 6 and 12 weeks,the micro-CT evaluation and histological analysis consistently highlighted the ability of this PDA coating to increase new bone formation adjacent to coated PEEK implant and enhance bone-implant interfacial integration.These results were proven to be related to the synergistic effect that citrate facilitated a 2-fold influx of copper into cells,which not only enhanced the bacteria-killing ability but also encouraged bone regeneration of implants.This present work provides an effective method to control infections while promoting osseointegration simultaneously,which will show tremendous clinical application and can be a solution to current challenges facing orthopedics.Jianglong Yan Dandan Xiab Pan Xionga Yangyang Li Wenhao Zhou Qiyao Li Pei Wang Yufeng Zheng Yan Cheng 2021Journal of Materials Science & Technology2021,,12:1

15Dynamic Trajectory Planning of Autonomous Lane Change at Medium and Low Speeds Based on Elastic Soft Constraint of the Safety Domain显示文摘Most current research on the trajectory planning of the autonomous lane change focuses on high-speed scenarios and assumes that the states of the surrounding vehicles keep stable during the lane change.The methods based on geometric-curve are mostly used for trajectory planning.In this paper,considering the inevitable development of the autonomous driving,the surrounding vehicles are assumed to be driven by human drivers,while the ego vehicles are able to autonomously change lanes.Representative local lane-change scenarios are then designed and analyzed in detail aiming at medium-and low-speed lane-change conditions.Additionally,in contrast with most research,dynamic trajectory planning which considers the possible state variations of the surrounding vehicles and the driver characteristics is studied and described by a fifth-order polynomial function.The safety and comfort of the dynamic trajectory planning are validated through simulation.Moreover,the elastic soft constraint of the safety domain is designed,whereby the sensitivity of the studied dynamic trajectory planning system is reduced under the premise of ensuring safety.The effectiveness of the elastic soft constraint in terms of improving comfort during the lane change is verified through simulation.The availability of the dynamic trajectory planning system with the elastic soft constraint is demonstrated with the addition of trajectory tracking based on model predictive control,showing its potential in practical applications.Yangyang Wang Ding Pan Hangyun Deng Yuanxing Jiang Zhiguang Liu 2020Automotive Innovation2020,3,1:1

17Comparisons of Metabolic Profiles for Carbohydrates,Amino Acids,Lipids,Fragrance and Flavones During Grain Development in indica Rice Cultivars显示文摘We used a widely targeted metabolomics approach to examine the metabolic changes in three pedigreed indica cultivars(Meixiangzhan 2,Meisizhan and Qixinzhan),with different eating qualities,at 8,15 and 30 d after flowering(DAF)to explore the formation mechanism of rice eating and nutritional qualities at a global metabolic level.A total of 623 metabolites were identified,and results showed that metabolic variations among rice cultivars decreased with grain developmental stage,suggesting that sufficient carbohydrate and amino acid supply during grain development may contribute to excellent rice eating and nutritional quality formation.Lysophosphatidylcholines 19:0 and 16:1 were beneficial for excellent eating quality formation during grain development.Rice fragrance was attributed mainly to spermidine andγ-aminobutyric acid.Rice cultivars with excellent eating quality at 15-30 DAF had relatively higher flavone content,possibly because they had adequate carbohydrate and amino acid contents during grain development.These results provided insight into the mechanisms for establishing rice eating and nutritional qualities during grain formation at a global metabolic level,and can be applied towards improving rice quality.CHEN Yibo WANG Zhidong WANG Chongrong LI Hong HUANG Daoqiang ZHOU Degui ZHAO Lei PAN Yangyang GONG Rong ZHOU Shaochuan 2022Rice science2022,29,2:0
18Insertion/deletion variants within the IGF2BP2 gene identified in reported genome-wide selective sweep analysis reveal a correlation with goat litter size显示文摘Insulin-like growth factor 2 m RNA-binding protein 2(IGF2 BP2,also called IMP2)plays an essential role in the development and maturation of germ cells and embryos and is a candidate gene for goat litter size,based on a previous genomewide selective sweep analysis.In this study,the m RNA expression level of IGF2 BP2 was found to be significantly higher in a single-lamb group than in a multi-lamb group.Insertions/deletions(indels)within the goat IGF2 BP2 gene,including P4-Ins-13 bp and P5-Del-12 bp,were verified in 918 Shaanbei White Cashmere(SBWC)female goats.The minor allelic frequencies(MAFs)of P4-Ins-13 bp and P5-Del-12 bp loci were 0.349 and 0.295,respectively.Analysis using the Chi-square(χ^(2))test showed that the genotype(χ^(2)=14.479,P=0.006)distribution of P4-Ins-13 bp was significantly different between the single-lamb and multi-lamb groups.Correlation analysis demonstrated that P4-Ins-13 bp was significantly associated with goat litter size(P=0.022),and individual goats with the homozygous deletion/deletion(DD)genotype produced more litters than other goats.Therefore,considered as a potential molecular marker significantly related to lambing traits,the P4-Ins-13 bp mutation of the goat IGF2 BP2 gene can be used in goat breeding with practical molecular marker-assisted selection(MAS)to optimize female reproduction and improve economic efficiency in the goat industry.Dongyun XIN Yangyang BAI Yi BI Libang HE Yuxin KANG Chuanying PAN Haijing ZHU Hong CHEN Lei QU Xianyong LAN 2021Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021,22,9:0
19Bilayer tellurene-metal interfaces显示文摘Tellurene, an emerging two-dimensional chain-like semiconductor, stands out for its high switch ratio, carrier mobility and excellent stability in air. Directly contacting the 2D semiconductor materials with metal electrodes is a feasible doping means to inject carriers. However, Schottky barrier often arises at the metal–semiconductors interface, impeding the transport of carriers. Herein, we investigate the interfacial properties of BL tellurene by contacting with various metals including graphene by using ab initio calculations and quantum transport simulations. Vertical Schottky barriers take place in Ag, Al, Au and Cu electrodes according to the maintenance of the noncontact tellurene layer band structure. Besides, a p-type vertical Schottky contact is formed due to the van der Waals interaction for graphene electrode. As for the lateral direction, p-type Schottky contacts take shape for bulk metal electrodes(hole Schottky barrier heights(SBHs) ranging from 0.19 to 0.35 eV). Strong Fermi level pinning takes place with a pinning factor of 0.02. Notably, a desirable p-type quasi-Ohmic contact is developed for graphene electrode with a hole SBH of 0.08 eV. Our work sheds light on the interfacial properties of BL tellurene based transistors and could guide the experimental selections on electrodes.Hua Pang Jiahuan Yan Jie Yang Shiqi Liu Yuanyuan Pan Xiuying Zhang Bowen Shi Hao Tang Jinbo Yang Qihang Liu Lianqiang Xu Yangyang Wang Jing Lv 2019Journal of Semiconductors2019,40,6:0
20BiodMHC:an online server for the prediction of MHC class Ⅱ-peptide binding affinity显示文摘Effective identification of major histocompatibility complex (MHC) molecules restricted peptides is a critical step in discovering immune epitopes. Although many online servers have been built to predict class Ⅱ MHC-peptide binding affinity, they have been trained on different datasets, and thus fail in providing a unified comparison of various methods. In this paper, we present our implementation of seven popular predictive methods, namely SMM-align, ARB, SVR-pairwise, Gibbs sampler, ProPred, LP-top2, and MHCPred, on a single web server named BiodMHC (http://biod.whu.edu.cn/BiodMHC/index.html, the software is available upon request). Using a standard measure of AUC (Area Under the receiver operating characteristic Curves), we compare these methods by means of not only cross validation but also prediction on independent test datasets. We find that SMM-align, ProPred, SVR-pairwise, ARB, and Gibbs sampler are the five best-performing methods. For the binding affinity prediction of class Ⅱ MHC-peptide, BiodMHC provides a convenient online platform for researchers to obtain binding information simultaneously using various methods.Lian Wang Danling Pan Xihao Hu Jinyu Xiao Yangyang Gao Huifang Zhang Yan Zhang Juan Liu Shanfeng Zhu 2009Journal of Genetics and Genomics2009,36,5:0
