| 1 | Liberation characteristics of coal middlings comminuted by jaw crusher and ball mill显示文摘The associated minerals make coal middlings possess a relatively high ash content.Subsequent liberation through size reduction can cause recovery increase.However,effect of comminution facilities on mineral liberation of middlings was ignored.This paper studied the liberation characteristics of middlings crushed with different kinds of fragmentation forces.Middlings of 3 mm+0.5 mm sampled from a dense medium cyclone were comminuted by a jaw crusher and a ball mill to 0.5 mm with similar size distribution respectively.The generating mechanism of fnes was also analyzed.Full densimetric analyses indicate that mineral liberation of the product crushed by the jaw crusher is better than that by the ball mill at each fraction.For sizes of 0.125 mm+0.074 mm and 0.074 mm,yields of the product with ash content 11%comminuted by jaw crusher are nearly 20%higher than that by the ball mill.Sectional micrographs observed by the scanning electron microscopy(SEM)also show the same law for these two fractions and some intergrowth particles still exist in the fraction of 0.5 mm+0.25 mm. | Xie Weining He Yaqun Zhu Xiangnan Ge Linhan Huang Yajun Wang Haifeng | 2013 | International Journal of Mining Science and Technology2013,23,5: | 12 |

| 4 | Prioritizing natural-selection signals from the deep-sequencing genomic data suggests multi-variant adaptation in Tibetan highlanders显示文摘Human genetic adaptation to high altitudes(>2500 m)has been extensively studied over the last few years,but few functional adaptive genetic variants have been identified,largely owing to the lack of deep-genome sequencing data available to previous studies.Here,w e build a list of putative adaptive variants,including 63 missense,7 loss-of-function;1,298 evolutionarily conserved variants and 509 expression quantitative traits loci.Notably,the top signal of selection is located in TMEM 247,a transmembrane protein-coding gene.The Tibetan version of TMEM 247 harbors one high-frequency(76.3%)missense variant,rsl 16983452(c.248C>T;p.Ala83Val);with the T allele derived from archaic ancestry and carried by>94%of Tibetans but absent or in low frequencies(<3%)in non-Tibetan populations.The rsl 16983452-T is strongly and positively correlated with altitude and significantly associated with reduced hemoglobin concentration(p=5.78×10^-5),red blood cell count(p=5.72×10^-7)and hematocrit(p=2.57×10^-6).In particular,TMEM247-rs 116983452 shows greater effect size and better predicts the phenotypic outcome than any E P A S1 variants in association with adaptive traits in Tibetans.Modeling the interaction between TM£M247-rsl 16983452 and EPAS1 variants indicates weak but statistically significant epistatic effects.Our results support that multiple variants may jointly deliver the fitness of the Tibetans on the plateau,where a complex model is needed to elucidate the adaptive evolution mechanism. | Lian Deng Chao Zhang Kai Yuan Yang Gao Yuwen Pan Xueling Ge Yaoxi He Yuan Yuan Yan Lu Xiaoxi Zhang Hao Chen Haiyi Lou Xiaoji Wang Dongsheng Lu Jiaojiao Liu Lei Tian Qidi Feng Asifullah Khan Yajun Yang Zi-Bing Jin Jian Yang Fan Lu Jia Qu Longli Kang Bing Su Shuhua Xu | 2019 | National Science Review2019,6,6: | 9 |
| 5 | Vertically standing PtSe_2 film: a saturable absorber for a passively mode-locked Nd:LuVO_4 laser显示文摘The novel vertically standing Pt Se2 film on transparent quartz was prepared by selenization of platinum film deposited by the magnetron sputtering method, and an Nd:Lu VO4 passively mode-locked solid-state laser was realized by using the fabricated Pt Se2 film as a saturable absorber. The X-ray diffraction pattern and Raman spectrum of the film indicate its good crystallinity with a layered structure. The thickness of Pt Se2 film is measured to be 24 nm according to the cross-section height profile of the atomic force microscope image. Highresolution transmission electron microscopy images clearly demonstrate its vertically standing structure with an interlayer distance of 0.54 nm along the c-axis direction. The modulation depth(ΔT) and saturation fluence(Φs)of Pt Se2 film are measured to be 12.6% and 17.1 μJ∕cm2, respectively. The obtained mode-locked laser spectrum has a central wavelength of 1066.573 nm, with a 3 d B bandwidth of 0.106 nm. The transform limited pulse width of the mode-locked laser was calculated to be 15.8 ps. A maximum average output power of 180 m W with a working repetition rate of 61.3 MHz is obtained. To the best of our knowledge, this is the first report of the generation of ultrafast mode-locked laser pulses by using layered Pt Se2 as a saturable absorber. | LILI TAO XIAOWEN HUANG JUNSHAN HE YAJUN LOU LONGHUI ZENG YONGHUI LI HUI LONG JINGBO LI LING ZHANG YUEN HONG TSANG | 2018 | Photonics Research2018,6,7: | 8 |
| 6 | The biological effect of recombinant humanized collagen on damaged skin induced by UV-photoaging:An in vivo study显示文摘The application of medical devices to repair skin damage is clinically accepted and natural polymer enjoys an important role in this field,such as collagen or hyaluronic acid,etc.However,the biosafety and efficacy of these implants are still challenged.In this study,a skin damage animal model was prepared by UV-photoaging and recombinant humanized type Ⅲ collagen(rhCol Ⅲ)was applied as a bioactive material to implant in vivo to study its biological effect,comparing with saline and uncrosslinked hyaluronic acid(HA).Animal skin conditions were non-invasively and dynamically monitored during the 8 weeks experiment.Histological observation,specific gene expression and other molecular biological methods were applied by the end of the animal experiment.The results indicated that rhCol Ⅲ could alleviate the skin photoaging caused by UV radiation,including reduce the thickening of epidermis and dermis,increase the secretion of Collagen Ⅰ(Col Ⅰ)and Collagen Ⅲ(Col Ⅲ)and remodel of extracellular matrix(ECM).Although the cell-material interaction and mechanism need more investigation,the effect of rhCol Ⅲ on damaged skin was discussed from influence on cells,reconstruction of ECM,and stimulus of small biological molecules based on current results.In conclusion,our findings provided rigorous biosafety information of rhCol Ⅲ and approved its potential in skin repair and regeneration.Although enormous efforts still need to be made to achieve successful translation from bench to clinic,the recombinant humanized collagen showed superiorities from both safety and efficacy aspects. | Jing Wang He Qiu Yang Xu Yongli Gao Peijie Tan Rui Zhao Zhanhong Liu Yajun Tang Xiangdong Zhu Chongyun Bao Hang Wang Hai Lin Xingdong Zhang | 2022 | Bioactive Materials2022,7,5: | 7 |
| 7 | Combined effects of volume ratio and nitrate recycling ratio on nutrient removal,sludge characteristic and microbial evolution for DPR optimization显示文摘The optimization of volume ratio(V_(An)/V_(A)/V_(0))and nitrate recycling ratio(R)in a two-sludge denitrifying phosphorus removal(DPR)process of Anaerobic Anoxic Oxic-Moving Bed Biofilm Reactor(A^(2)/O-MBBR)was investigated.The results showed that prolonged anaerobic retention time(HRT An:1.25→3.75 hr)exerted favorable effect on chemical oxygen demand(COD)removal(57.26%→73.54%),poly-β-hydroxyalkanoates(PHA)synthesis(105.70→138.12 mg COD/L)and PO_(4)^(3-)release(22.3→38.9 mg/L).However,anoxic retention time(HRT A)and R exhibited positive correlation with PHA utilization(43.87%-81.34%)and denitrifying phosphorus removal(DPR)potential(NO_(3)-/PO^(3-)_(4):0.57-1.34 mg/mg),leading to dramatical TN removal variations from 68.86%to 81.28%.Under the V An/V A/V O ratio of 2:6:0,sludge loss deteriorated nutrient removals but the sludge bioactivity quickly recovered when the oxic zone was recovered.The sludge characteristic and microstructure gradually transformed under the dissolved oxygen(DO)control(1.0-1.5→1.5-2.0 mg/L),in terms of sludge volume index(SVI:194→57 m L/g VSS),median-particle-size(D 50:99.6→300.5μm),extracellular polymeric substances(EPS)(105.62→226.18 mg/g VSS)and proteins/polysaccharides(PN/PS)ratio(1.52→3.46).Fluorescence in situ hybridization(FISH)results showed that phosphorus accumulation organisms(PAOs)(mainly Cluster I of Accumulibacter,contribution ratio:91.79%-94.10%)dominated the superior DPR performance,while glycogen accumulating organisms(GAOs)(mainly Competibacter,contribution ratio:82.61%-86.89%)was responsible for deteriorative TN and PO_(4)^(3-)removals.The optimal HRT A and R assembled around 5-6.5 hr and 300%-400%based on the PHA utilization and DRP performance,and the oxic zones also contributed to PO_(4)^(3-)removal although it showed low dependence on DO concentration and oxic retention time(HRT_(0)). | Miao Zhang Jing Gao Yajun Fan Xiaoge Wu Jun Wu Chengda He | 2021 | Journal of Environmental Sciences2021,33,6: | 6 |

| 9 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,3: | 6 |

Fluorophosphate glasses with low nonlinear refractive index(n_2=0.6–0.86) and long fluorescence lifetime(430–510 μs) are investigated for the purpose of decreasing B integral in high-power laser system. The properties of all these glasses are presented and compared with those of commercial neodymium laser glasses. | Dongbing He Shuai Kang Liyan Zhang Lin Chen Yajun Ding Qianwen Yin Lili Hu | 2017 | High Power Laser Science and Engineering2017,5,1: | 6 |
| 11 | Neutralization of interleukin-17A alleviates burn-induced intestinal barrier disruption via reducing pro-inflammatory cytokines in a mouse model显示文摘Background:The intestinal barrier integrity can be disrupted due to burn injury,which is responsible for local and systemic inflammatory responses.Anti-inflammation strategy is one of the proposed therapeutic approaches to control inflammatory cascade at an early stage.Interleukin-17A(IL-17A)plays a critical role in inflammatory diseases.However,the role of IL-17A in the progression of burn-induced intestinal inflammation is poorly understood.In this study,we aimed to investigate the effect of IL-17A and associated pro-inflammatory cytokines that were deeply involved in the pathogenesis of burn-induced intestinal inflammatory injury,and furthermore,we sought to determine the early source of IL-17A in the intestine.Methods:Mouse burn model was successfully established with infliction of 30%total body surface area scald burn.The histopathological manifestation,intestinal permeability,zonula occludens-1 expression,pro-inflammatory cytokines were determined with or without IL-17A-neutralization.Flow cytometry was used to detect the major source of IL-17A^(+)cells in the intestine.Results:Burn caused intestinal barrier damage,increase of intestinal permeability,alteration of zonula occludens-1 expressions,elevation of IL-17A,IL-6,IL-1βand tumor necrosis factor-α(TNF-α),whereas IL-17A neutralization dramatically alleviated burn-induced intestinal barrier disruption,maintained zonula occludens-1 expression,and noticeably,inhibited pro-inflammatory cytokines elevation.In addition,we observed that the proportion of intestinal IL-17A^(+)Vγ4^(+)T subtype cells(but not IL-17A^(+)Vγ1^(+)T subtype cells)were increased in burn group,and neutralization of IL-17A suppressed this increase.Conclusions:The main original findings of this study are intestinal mucosa barrier is disrupted after burn through affecting the expression of pro-inflammatory cytokines,and a protective role of IL-17A neutralization for intestinal mucosa barrier is determined.Furthermore,Vγ4^(+)T cells are identified as the major early producers of IL-17A that orchestrate an inflammatory response in the burn model.These data suggest that IL-17A blockage may provide a unique target for therapeutic intervention to treat intestinal insult after burn. | Yajun Song Yang Li Ya Xiao Wengang Hu Xu Wang Pei Wang Xiaorong Zhang Jiacai Yang Yong Huang Weifeng He Chibing Huang | 2019 | Burns & Trauma2019,7,1: | 5 |
| 12 | Regulation of mitochondrial NAD pool via NAD^+ transporter 2 is essential for matrix NADH homeostasis and ROS production in Arabidopsis显示文摘Reactive oxygen species(ROS) play a crucial role in numerous biological processes in plants, including development, responses to environmental stimuli, and programmed cell death(PCD). Deficiency in MOSAIC DEATH 1(MOD1), a plastid-localized enoyl-ACP reductase essential for de novo fatty acid biosynthesis in Arabidopsis thaliana, leads to the increased malate export from chloroplasts to mitochondria, and the subsequent accumulation of mitochondria-generated ROS and PCD. In this study, we report the identification and characterization of a mod1 suppressor, som592. SOM592 encodes mitochondrion-localized NAD^+ transporter 2(NDT2). We show that the mitochondrial NAD pool is elevated in the mod1 mutant. The som592 mutation fully suppressed mitochondrial NADH hyper-accumulation, ROS production, and PCD in the mod1 mutant, indicating a causal relationship between mitochondrial NAD accumulation and ROS/PCD phenotypes. We also show that in wild-type plants, the mitochondrial NAD+uptake is involved in the regulation of ROS production in response to continuous photoperiod. Elevation of the alternative respiration pathway can suppress ROS accumulation and PCD in mod1, but leads to growth restriction. These findings uncover a regulatory mechanism for mitochondrial ROS production via NADH homeostasis in Arabidopsis thaliana that is likely important for growth regulation in response to altered photoperiod. | Lilan Luo Yajun He Yannan Zhao Qian Xu Jian Wu Haiyan Ma Hongyan Guo Lin Bai Jianru Zuo Jian-Min Zhou Hong Yu Jiayang Li | 2019 | Science China(Life Sciences)2019,62,8: | 5 |
| 13 | Synthesis of hierarchical dendritic micro–nano structure ZnFe_2O_4 and photocatalytic activities for water splitting显示文摘Hierarchical dendritic micro–nano structure Zn Fe_2O_4 have been prepared by electrochemical reduction and thermal oxidation method in this work. X-ray diffractometry, Raman spectra and field-emission scanning electron microscopy were used to characterize the crystal structure, size and morphology. The results show that the sample(S-2) is composed of pure ZnFe_2O_4 when the molar ratio of Zn^(2+)/Fe^(2+)in the electrolyte is 0.35. Decreasing the molar ratio of Zn^(2+)/Fe^(2+), the sample(S-1) is composed of ZnFe_2O_4 and α-Fe_2O_3, whereas increasing the molar ratio of Zn^(2+)/Fe^(2+), the sample(S-3) is composed of ZnFe_2O_4 and Zn O. The lattice parameters of ZnFe_2O_4 are influenced by the molar ratio of Zn^(2+)/Fe: Zn at excess decreases the cell volume whereas Fe at excess increases the cell volume of Zn Fe_2O_4. All the samples have the dendritic structure, of which S-2 has micron-sized lush branches with nano-sized leaves. UV–Vis diffuse reflectance spectra were acquired by a spectrophotometer. The absorption edges gradually blue shift with the increase of the molar ratio of Zn^(2+)/Fe^(2+). Photocatalytic activities for water splitting were investigated under Xe light irradiation in an aqueous olution containing 0.1 mol·L^(-1)Na_2S/0.02 mol·L^(-1)Na_2SO_3 in a glass reactor. The relatively highest photocatalytic activity with 1.41 μmol·h-1· 0.02 g^(-1)was achieved by pure ZnFe_2O_4sample(S-2). The photocatalytic activity of the mixture phase of Zn Fe_2O_4 and α-Fe_2O_3(S-1) is better than ZnF e_2O_4 and ZnO(S-3). | Zhongping Yao Yajun Zhang Yaqiong He Qixing Xia Zhaohua Jiang | 2016 | Chinese Journal of Chemical Engineering2016,24,8: | 4 |

| 18 | Using humic acid for remediation of sandy soils contaminated by heavy metal显示文摘This paper presents the development of a new remediation technology for contaminated sandy soil using humic acid (HA). Distribution of amount of Cr (VI) in the aqueous or solid system containing humic acid and sandy soil, was studied using batch experiments, es-pecially for effects of reaction time, pH, concentrations, temperature and irradiation on the reduction of Cr (VI), and the optimum reaction conditions. The results indicated a significant increase of the adsorption of Cr (VI) because of the complexion reaction between HA and Cr (VI) that occurred under acidic condition. The reaction mechanisms of HA with chromium on sand surfaces were certified. Thus it came to a conclusion that HA could be used effectively on remediation of Cr (VI)-contaminated soil and groundwater in a wide range of pH, with or without sunlight. These results suggest that the organic-inorganic complex-such as sandy soils coated with humic substances-is important as a metal reservoir in the environment. | YaJun Wang 1, HongLang Xiao 1, JinXi Wang 2, Yong Wang 3 1.

| 19 | Rice Heavy Metal P-type ATPase OsHMA6 Is Likely a Copper Efflux Protein显示文摘P1B-type heavy metal ATPases(HMAs)are transmembrane metal-transporting proteins that play a key role in metal homeostasis.We here reported the characterization of rice OsHMA6,a member of the P1B-type ATPase family.Phylogenetic tree analysis showed that OsHMA6 belonged to the Cu/Ag subgroup of the HMA family and had a close evolutionary relationship with OsHMA9.Amino acid sequence alignment showed 82.78%consistency between OsHMA6 and OsHMA9.OsHMA6 expressed in all organs at different growth stages,including spikelet,and abundant in leaf blades,however,OsHMA9 most strongly expressed in roots,but very low in spikelet.Excessive Cu^2+can up-regulate the expression of OsHMA6 and OsHMA9 in rice seedlings.The heterologous expression in yeast showed that OsHMA6 can significantly rescue the growth of yeast strain CM52 when supplied with 3 or 6 mmol/L Cu^2+.Compared with the empty vector pYES2,the Cu concentration in OsHMA6-pYES2 decreased by 23.4%and 30.3%under 3 or 6 mmol/L Cu2+,respectively.Subcellular localization revealed that OsHMA6 was located in the plasma membrane.These results suggested that OsHMA6,similar to OsHMA9,is likely a copper efflux protein located in the plasma membrane. | ZOU Wenli LI Chang ZHU Yajun CHEN Jingguang HE Haohua YE Guoyou | 2020 | Rice science2020,27,2: | 2 |
