| 1 | Responses of ammonia-oxidizing microorganisms to biochar and compost amendments of heavy metals-polluted soil显示文摘Heavy metal pollution affects soil ecological function.Biochar and compost can effectively remediate heavy metals and increase soil nutrients.The effects and mechanisms of biochar and compost amendments on soil nitrogen cycle function in heavy-metal contaminated soils are not fully understood.This study examined how biochar,compost,and their integrated use affected ammonia-oxidizing microorganisms in heavy metal polluted soil.Quantitative PCR was used to determine the abundance of ammonia-oxidizing archaea(AOA)and bacteria(AOB).Ammonia monooxygenase(AMO)activity was evaluated by the enzymelinked immunosorbent assay.Results showed that compost rather than biochar improved nitrogen conversion in soil.Biochar,compost,or their integrated application significantly reduced the effective Zn and Cd speciation.Adding compost obviously increased As and Cu effective speciation,bacterial 16 S rRNA abundance,and AMO activity.AOB,stimulated by compost addition,was significantly more abundant than AOA throughout remediation.Correlation analysis showed that AOB abundance positively correlated with NO_(3)^(-)-N(r=0.830,P<0.01),and that AMO activity had significant correlation with EC(r=-0.908,P<0.01)and water-soluble carbon(r=-0.868,P<0.01).Those seem to be the most vital factors affecting AOB community and their function in heavy metal-polluted soil remediated by biochar and compost. | Mingyue Li Jiachao Zhang Xiao Yang Yaoyu Zhou Lihua Zhang Yuan Yang Lin Luo Qingyun Yan | 2021 | Journal of Environmental Sciences2021，33，4： | 5 |

| 3 | A downshifting Eu^3+doped glass embedded with concave pyramid microstructure to improve the efficiency of silicon solar cell显示文摘The average photoelectric conversion efficiency(PCE)of a bare mono crystalline silicon solar cell is 14.71%±0.03%under AM1.5.It decreases to 14.20%±0.005%when covering an un-doped flat glass on the solar cell,and it goes down to 14.10%±0.005%by using a 5 wt%Eu^3+doped glass.The absorptions of the Eu^3+doped CPM glass one-to-one match the excitation spectra at 362,381,393,400,413 and464 nm,which are related to the transitions of 7 F0→(5 D4,5 G2,5 L6,5 D3),7 F1→5 D3,and 7 F0→5 D2,respectively.In addition,a concave pyramid microstructure(CPM)is embedded in the glass surface to increase light transmittance.The average PCE increases to 14.61%±0.07%when a 5 wt%Eu^3+doped CPM glass covers on the silicon solar cell.Compared with the un-doped flat glass,a net increase of the PCE is0.41%,where the 0.16%increment of PCE is from the lighting trapping of the CPM structure,and the downshifting of near ultraviolet(NUV)light by Eu^3+ion donates the other 0.25%increment.It confirms that the as-prepared Eu^3+doped CPM glass has a good downshifting and antireflection function. | Xing Yang Jiachao Chen Songsheng Zheng Chao Chen | 2020 | Journal of Rare Earths2020，38，11： | 1 |
| 4 | Pathological Networks Involving Dysmorphic Neurons in Type ⅡFocal Cortical Dysplasia显示文摘Focal cortical dysplasia(FCD)is one of the most common causes of drug-resistant epilepsy.Dysmorphic neurons are the major histopathological feature of typeⅡFCD,but their role in seizure genesis in FCD is unclear.Here we performed whole-cell patch-clamp recording and morphological reconstruction of cortical principal neurons in postsurgical brain tissue from drug-resistant epilepsy patients.Quantitative analyses revealed distinct morphological and electrophysiological characteristics of the upper layer dysmorphic neurons in typeⅡFCD,including an enlarged soma,aberrant dendritic arbors,increased current injection for rheobase action potential firing,and reduced action potential firing frequency.Intriguingly,the upper layer dysmorphic neurons received decreased glutamatergic and increased GABAergic synaptic inputs that were coupled with upregulation of the Na^(+)-K^(+)-Cl^(−)cotransporter.In addition,we found a depolarizing shift of the GABA reversal potential in the CamKⅡ-cre::PTENflox/flox mouse model of drug-resistant epilepsy,suggesting that enhanced GABAergic inputs might depolarize dysmorphic neurons.Thus,imbalance of synaptic excitation and inhibition of dysmorphic neurons may contribute to seizure genesis in typeⅡFCD. | Yijie Shao Qianqian Ge Jiachao Yang Mi Wang Yu Zhou Jin-Xin Guo Mengyue Zhu Jiachen Shi Yiqi Hu Li Shen Zhong Chen Xiao-Ming Li Jun-Ming Zhu Jianmin Zhang Shumin Duan Jiadong Chen | 2022 | Neuroscience Bulletin2022，38，9： | 1 |
| 5 | Novel potential XOD inhibitory peptides derived from Trachinotus ovatus:Isolation,identification and structure-function analysis显示文摘This study aimed to isolate and identify the novel potential Xanthine oxidase(XOD)inhibitory peptides derived from Trachinotus ovatus hydrolysate(TOH)(hydrolysis by neutral protease),and investigate their structure-function relationship.Initially,TOH was separated to four fractions(F1–F4)by gel filtration chromatography and F4 was chosen with higher XOD inhibitory rate(85.16%±0.566,25 mg/mL)and lower molecular weight(95.73%,<1000 Da).F4 was further characterized by reversed-phase high performance liquid chromatography(RP-HPLC)coupled with Nano-HPLC-MS/MS and four peptides(FPAW,LLPW,WLLP and FHLP)were identified with IC50 value of 3.81±0.18 mM,4.17±0.12 mM,43.06±0.73 mM,and over 50.00 mM respectively.It can be concluded that Trp-containing peptides especially located in C-terminal could inhibit XOD effectively.Moreover,the XOD-inhibiting actions of these peptides involvedπ-πstacking(Phe914 and Phe1009 in XOD),hydrogen bonding via molecular docking.Lineweaver-Burk equation showed the inhibition type of FPAW was a mixed inhibition.Circular dichroism(CD)spectra indicated FPAW could combine and change the secondary structure of XOD.Therefore,two peptides of FPAW and LLPW might have potential to be used to alleviate hyperuricemia in the future. | Mengfan Hou Huan Xiang Xiao Hu Shengjun Chen Yanyan Wu Jiachao Xu Xianqing Yang | 2022 | Food Bioscience2022，47，3： | 1 |
| 6 | 3-23 Research Progress in Group of Energy Materials in 2014显示文摘The progress of research going on in Group of Energy Materials (GEM), Material Research Center, in 2014 isin the following three aspects.1. Facility developmentIn order to push forward our study on fusion reactor materials, we upgraded the irradiation terminal (128#)of the sector focused cyclotron (SFC) at HIRFL, by developing a new specimen stage specific for irradiation withlow-fluence scattered ions. So far the terminal is capable of irradiation to both very low fluences (106 ions/cm2) andvery high fluences (typically 1016 ions/cm2) for various materials. Specimen temperature can be readily controlledusing the L-N2 cooling stage or the the high-T stage (up to 600 oC). Our recent investigation with transmissionelectron microscopy (TEM) of the defects produced by high-energy Ne ions in steel specimens provides a clearevidence that defects were produced uniformly along the depth in the specimen, indicating that the energy degraderof the terminal works effectively to disperse the ion energy in a wide range. A photo of the terminal together witha SRIM estimate of depth profiles of damage in an 8% Cr reduced activation ferritic/martensitic steel (RAFMS) isshown in Fig. 1. | Zhang Chonghong Song Yin Yang Yitao Zhang Liqing Gou Jie Chen Jiachao J.

| 8 | Core processing neuron-enabled circuit motifs for neuromorphic computing显示文摘Based on brain-inspired computing frameworks,neuromorphic systems implement large-scale neural networks in hardware.Although rapid advances have been made in the development of artificial neurons and synapses in recent years,further research is beyond these individual components and focuses on neuronal circuit motifs with specialized excitatory-inhibitory(E-I)connectivity patterns.In this study,we demonstrate a core processor that can be used to construct commonly used neuronal circuits.The neuron,featuring an ultracompact physical configuration,integrates a volatile threshold switch with a gate-modulated two-dimensional(2D)MoS2 field-effect channel to process complex E-I spatiotemporal spiking signals.Consequently,basic neuronal circuits are constructed for biorealistic neuromorphic computing.For practical applications,an algorithm-hardware co-design is implemented in a gatecontrolled spiking neural network with substantial performance improvement in human speech separation. | Hanxi Li Jiayang Hu Anzhe Chen Yishu Zhang Chenhao Wang Beiduo Wang Yi Tong Jiachao Zhou Kian Ping Loh Yang Xu Tawfique Hasan Bin Yu | 2023 | InfoMat2023，5，11： | 0 |
| 9 | External-to-internal synergistic strategy to enable multi-scale stabilization of LiCoO_(2)at high-voltage显示文摘High-voltage LiCoO_(2)(LCO)offers a prelude to breaking the bottleneck of the energy density of lithium-ion batteries,however,LiCoO_(2)is subject to serious structural and interfacial degradation above voltages>4.55 V(vs.Li/Li^(+)).Herein,an in-situ Li_(6.25)La_(3)Zr_(2)A_(l0.25)O_(12)(LLZAO)layer is constructed on the LCO surface to achieve operating voltage at 4.6 V.The detailed characterizations(ex-situ XRD,ex-situ Raman,DFT,etc.)reveal that the LLZAO layer greatly enhances Li+conductivity attributed to the ionconducting layer on the surface/interface,and closely combines with LiCoO_(2)particle to ensure stable cathode/electrolyte interface,thus suppressing the highly reactive Co^(4+)and O^(-)triggered surface side reactions at high-voltage.Moreover,the introduction of La^(3+)/Zr^(4+)/Al^(3+)with a larger ionic radius(La^(3+)/Zr^(4+)are larger than Co^(3+))and weaker electronegativity(La/Zr/Al are weaker than Co)into Co^(3+)sites readjusts the electron cloud density between Co–O–Li,which reinforces the Co–O bond and widens the band-center gap of Co 3d and O 2p,thus restraining the detrimental phase transition(from H3 to H1-3 phase)and the formation of Co_(3)O_(4)spinel phase(attributed to lattice oxygen release),subsequently alleviating the particle cracking and structural collapse during repeated Li^(+)de/intercalation.Therefore,after 100 cycles at 3.0–4.6 V,LCO@1.0LLZAO exhibits a superior discharge capacity of 188.5 m A h g^(-1),with a capacity retention of 85.1%.The above research has brought about meaningful guidance for the evolution of cathode materials with high voltage. | Shuaipeng Hao Yunjiao Li Jiachao Yang Shan Wang Zhouliang Tan Xiaoming Xi Zhenjiang He Panpan Zhang | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
| 10 | 3-26 Research Progress in Group of Energy Materials in 2015显示文摘The fracture behavior is a very important aspect of the mechanical properties of structure materials. For highenergy ions, their range in steels can be significantly larger than the average size of grains of steels, thus their irradiation can change the bulk properties of steels. It is therefore possible to study the fracture behavior of steel specimens irradiated with high-energy ions. | Zhang Chonghong Song Yin Yang Yitao Zhang Liqing Gou Jie Ding Zhaonan Chen Jiachao | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 11 | Occurrence, distribution and risk assessment of antibiotics at various aquaculture stages in typical aquaculture areas surrounding the Yellow Sea显示文摘The pollution of antibiotics commonly existed throughout the entire aquaculture process,but the residues of antibiotics at different aquaculture stages have rarely been studied.This study investigated the occurrence,distribution and risk assessment of antibiotics at different aquaculture stages (the non-aquaculture stage,the early aquaculture stage,the middle aquaculture stage,and the late aquaculture stage) in two typical marine aquaculture areas(Mahegang River and Dingzi Bay) surrounding the Yellow Sea.Fluoroquinolones and tetracyclines were commonly used antibiotics in the aquaculture of these areas with high detection frequencies (17%to 83%).Compared among four aquaculture stages,the highest concentration of antibiotics (9032.08 ng/L) in aquaculture ponds was detected at the late aquaculture stage.And the antibiotic pollution level of natural water was directly related to the aquaculture stages.Similarly,at the aquaculture stages,the detection frequency of antibiotics in sediments was higher than that at the non-aquaculture stage.Based on the correlation analysis,the concentration of main antibiotics in water showed a positive correlation with total nitrogen (p<0.05) and chlorophyll a (p<0.01),while it showed a negative correlation with salinity (p<0.01) in coastal water of the Dingzi Bay.According to the risk assessment,with the development of aquaculture stages,the selection pressure of fluoroquinolones and tetracyclines on resistant bacteria had increased.And the ecological risks caused by sulfonamides and tetracyclines to aquatic organisms had also increased markedly.Overall,this study may provide a reference for formulating regulatory policies regarding antibiotic use at different aquaculture stages. | Jiachao Zhang Xuanrui Zhang Yang Zhou Qianfan Han Xiaoli Wang Chao Song Shuguang Wang Shan Zhao | 2023 | Journal of Environmental Sciences2023，，4： | 0 |
