| 1 | Fate of antibiotics and antibiotic resistance genes in a full-scale restaurant food waste treatment plant:Implications of the roles beyond heavy metals and mobile genetic elements显示文摘Is our food safe and free of the crisis of antibiotics and antibiotic resistance (AR)?And will the derived food waste (FW) impose AR risk to the environment after biological treatment? This study used restaurant FW leachates flowing through a 200 tons-waste/day biological treatment plant as a window to investigate the fate of antibiotics and antibiotic-resistance genes (ARGs) during the acceptance and treatment of FW.Sulfonamides (sulfamethazine,sulfamethoxazole) and quinolones (ciprofloxacin,enrofloxacin,ofloxacin) were detected during FW treatment,while tetracyclines,macrolides and chloramphenicols were not observable.ARGs encoding resistance to sulfonamides,tetracyclines and macrolides emerged in FW leachates.Material flow analysis illustrated that the total amount of antibiotics (except sulfamethazine) and ARGs were constant during FW treatment processes.Both the concentration and total amount of most antibiotics and ARGs fluctuated during treatment,physical processes (screening,centrifugation,solid-liquid and oil-water separation) did not decrease antibiotic or ARGs concentrations or total levels permanently;the affiliated wastewater treatment plant appeared to remove sulfonamides and most ARGs concentrations and total amount.Heavy metals Ni,Co and Cu were important for disseminating antibiotics concentrations and MGEs for distributing ARGs concentrations.Humic substances (fulvic acids,hydrophilic fractions),C-associated and N-associated contents were essential for the distribution of the total amounts of antibiotics and ARGs.Overall,this study implied that human food might not be free of antibiotics and ARGs,and FW was an underestimated AR pool with various determinants.Nonetheless,derived hazards of FW could be mitigated through biological treatment with well-planned daily operations. | Pinjing He Zhuofeng Yu Liming Shao Yizhou Zhou Fan Lü | 2019 | Journal of Environmental Sciences2019，31，11： | 7 |
| 2 | Rational Fabrication of Superhydrophobic Nanocone Surface for Dynamic Water Repellency and Anti-icing Potential显示文摘In this work,a simple and economic route was presented to fabricate an anti-icing superhydrophobic surface with nanocone structures,which were constructed only by one-step facile method of hydrothermal treatment with zinc acetate on the aluminum substrate.After modifying with fluoroalkylsilane (FAS-17),the nanocone structures with the appropriate size could induce the high superhydrophobicity with the water contact angle reaching 160.2° ± 0.4° and the sliding angle only being 1 ° ± 0.5°.Under the dynamic environments,the impact droplets could rapidly bounced off the surface with the shorter contact time of^1 0.6 ms,and it was mainly attributing to lower capillary adhesive force (water adhesion force of 4.1 μN) induced by the open system of nanocone structures.Furthermore,the superhydrophobic nanocone surfaces were verified to be a promising anti-icing/icephobic materials,on which the water droplets needed to spend the time of ~517 s to complete the entire freezing process at-10 ℃,displaying the increased ~50 times of icing-delay performance comparing with untreated substrate.Even if ice finally was formed on the superhydrophobic nanocone surfaces,it could be easily removed away with lower ice adhesion of^45 kPa.The repeatable measurement of ice adhesion strength on the same place of the superhydrophobic surface is still far less than the surface ice adhesion of smooth substrate,exhibiting better stability. | Yuehan Xie Haifeng Chen Yizhou Shen Jie Tao Mingming Jin Yu Wu Wenqing Hou | 2019 | Journal of Bionic Engineering2019，16，1： | 7 |
| 3 | Intensifying Electron Utilization by Surface-Anchored Rh Complex for Enhanced Nicotinamide Cofactor Regeneration and Photoenzymatic CO_(2)Reduction显示文摘Solar-driven photocatalytic regeneration of cofactors,including reduced nicotinamide adenine dinucleotide(NADH),reduced nicotinamide adenine dinucleotide phosphate(NADPH),and reduced flavin adenine dinucleotide(FADH_(2)),could ensure the sustainable energy supply of enzymatic reactions catalyzed by oxidoreductases for the efficient synthesis of chemicals.However,the elevation of cofactor regeneration efficiency is severely hindered by the inefficient utilization of electrons transferred on the surface of photocatalysts.Inspired by the phenomenon of ferredoxin-NADP+reductase(FNR)anchoring on thylakoid membrane,herein,a homogeneous catalyst of rhodium(Rh)complex,[Cp_(∗)Rh(bpy)H_(2)O]^(2+),was anchored on polymeric carbon nitride(PCN)mediated by a tannic acid/polyethyleneimine(TA/PEI)adhesive layer,acquiring PCN@TA/PEI-Rh core@shell photocatalyst.Illuminated by visible light,electrons were excited from the PCN core,then transferred through the TA/PEI shell,and finally captured by the surface-anchored Rh for instant utilization during the regeneration of NADH.The TA/PEI-Rh shell could facilitate the electron transfer from the PCN core and,more importantly,achieved~1.3-fold elevation of electron utilization efficiency compared with PCN.Accordingly,the PCN@TA/PEI-Rh afforded the NADH regeneration efficiency of 37.8%after 20 min reaction under LED light(405 nm)illumination,over 1.5 times higher than PCN with free Rh.Coupling of the NADH regeneration system with formate dehydrogenase achieved continuous production of formate from carbon dioxide(CO_(2)).Our study may provide a generic and effective strategy to elevate the catalytic efficiency of a photocatalyst through intensifying the electron utilization. | Yuqing Cheng Jiafu Shi Yizhou Wu Xueying Wang Yiying Sun Ziyi Cai Yu Chen Zhongyi Jiang | 2021 | Research2021，，1： | 5 |
| 4 | Effects of scanning speed on microstructure in laser surface-melted single crystal superalloy and theoretical analysis显示文摘Scanning speed is a critical parameter for laser process,which can play a key role in the microstructure evolution of laser melting.In the laser melting of single crystal superalloy,the effects of scanning speed were investigated by experimental analysis and computational simulation.The laser was scanning along710 direction on(001) surface in different speeds.Solidification microstructures of dendrites growth direction and the primary dendritic spacing were analyzed by metallograph.Besides,a planar interface during solidification was taken into attention.Experiment results indicated that the primary dendritic spacing and thickness of planar interface decrease with the increase of speed.Through simulation,distribution of dendrites growth velocity and thermal gradient along dendrite growth direction were calculated,and the simulation of dendrites growth direction agreed with the experiment results.Additionally,a constant value was acquired which can be used to predict the primary dendritic spacing.Moreover,according to curve-fitting method and inequality relation,a model was proposed to predict the thickness of planar interface. | Guowei Wang Jingjing Liang Yanhong Yang Yu Shi Yizhou Zhou Tao Jin Xiaofeng Sun | 2018 | Journal of Materials Science & Technology2018，34，8： | 5 |
| 5 | A robust high-resolution details preserving denoising algorithm for meshes显示文摘Finely captured meshes often contain details like sharp edges, corners and shallow features. In order to improve the quality of these meshes, we present a robust and efficient high-resolution details-preserving mesh denoising algorithm. Our method consists of three stages. For each triangular face and its face neighborhood, we improve a robust density-based clustering method and apply it to the face neighborhood to extract a subset of neighbors which belong to the same cluster as the central face. And then, we filter the central face normal iteratively within this subset to remove noise. Because the faces within the extracted subset are not distributed across high-resolution details, our normal filtering can preserve such details as much as possible. Finally, we update the vertex positions to be consistent with the filtered face normals using a least-squares formulation. Experiments on various types of meshes indicate that our method has advantages over previous surface denoising methods. | FAN HanQi PENG QunSheng YU YiZhou | 2013 | Science China(Information Sciences)2013，56，9： | 2 |
| 6 | Microstructure evolution and mechanical behavior of Ni-based single crystal superalloy joint brazed with mixed powder at elevated temperature显示文摘Brazing of a Ni-based single crystal superalloy has been investigated with the additive Ni-based superalloy and filler Ni–Cr–W–B alloy at 1260℃, and attentions were paid to the microstructure evolution during brazing and the stress-rupture behavior at 980℃ of such brazed joints after homogenization. Microstructure in the brazed joint generally includes brazing alloy zone(BAZ), isothermally solidified zone(ISZ) and diffusion affected zone(DAZ). Microstructure evolution during this brazing process is discussed at the heating stage, the holding stage and the cooling stage respectively, according to the diffusion path of B atoms. Initially well-distributed γ’/γ’ microstructure in the homogenized bonded zone after heat treatment and substantial γ’ rafts enhance the post-brazed joint to obtain a stress-rupture lifetime of more than 120 h at 980℃/250 MPa. On the other hand, the decreased stress-rupture behavior of post-brazed joint, compared with parenting material, is ascribed to the presence of inside brazing porosity and stray grain boundary, which not only reduces the effective loading-carrying area but also offers preferential sites for creep vacancy aggregation to further soften stray grain boundary. And finally an early fracture of these post-brazed joints through the intergranular microholes aggregation and growth mode under this testing condition was observed. | Guanglei Wang Yuan Sun Xinguang Wang Jide Liu Jinlai Liu Jinguo Li Jinjiang Yu Yizhou Zhou Tao Jin Xudong Sun Xiaofeng Sun | 2017 | Journal of Materials Science & Technology2017，33，10： | 2 |

| 8 | Introducing B–N unit boosts photocatalytic H_(2)O_(2) production on metal-free g-C_(3)N_(4)nanosheets显示文摘Metal-free catalyst for photocatalytic production of H_(2)O_(2)is highly desirable with the long-term vision of artificial photosynthesis of solar fuel.In particular,the specific chemical bonds for selective H_(2)O_(2)photosynthesis via 2e–oxygen reduction reactions(ORR)remain to be explored for understanding the forming mechanism of active sites.Herein,we report a facile doping method to introduce boron-nitrogen(B–N)bonds into the structure of graphitic carbon nitride(g-C_(3)N_(4))nanosheets(denoted as BCNNS)to provide significant photocatalytic activity,selectivity and stability.The theoretical calculation and experimental results reveal that the electron-deficient B–N units serving as electron acceptors improve photogenerated charge separation and transfer.The units are also proved to be superior active sites for selective O_(2)adsorption and activation,reducing the energy barrier for*OOH formation,and thereby enabling an efficient 2e–ORR pathway to H_(2)O_(2).Consequently,with only bare loss of activity during repeated cycles,the optimal H2O2 production rate by BCNNS photocatalysts reaches 1.16 mmol·L^(–1)·h^(–1)under 365 nm-monochrome light emitting diode(LED365nm)irradiation,increasing nearly 2–5 times as against the state-of-art metal-free photocatalysts.This work gives the first example of applying B–N bonds to enhance the photocatalytic H_(2)O_(2)production as well as unveiling the underlying reaction pathway for efficient solar-energy transformations. | Weikang Wang Wei Zhang Yueji Cai Qing Wang Juan Deng Jingsheng Chen Zhifeng Jiang Yizhou Zhang Chao Yu | 2023 | Nano Research2023，16，2： | 2 |

| 15 | Feasibility of sentinel lymph node biopsy omission after integration of ^(18)F-FDG dedicated lymph node PET in early breast cancer: a prospective phase II trial显示文摘Objective:Sentinel lymph node biopsy(SLNB)is currently the standard of care in clinically node negative(cN0)breast cancer.The present study aimed to evaluate the negative predictive value(NPV)of 18F-FDG dedicated lymph node positron emission tomography(LymphPET)in cN0 patients.Methods:This was a prospective phase II trial divided into 2 stages(NCT04072653).In the first stage,cN0 patients underwent axillary LymphPET followed by SLNB.In the second stage,SLNB was omitted in patients with a negative preoperative axillary assessment after integration of LymphPET.Here,we report the results of the first stage.The primary outcome was the NPV of LymphPET to detect macrometastasis of lymph nodes(LN-macro).Results:A total of 189 patients with invasive breast cancer underwent LymphPET followed by surgery with definitive pathological reports.Forty patients had LN-macro,and 16 patients had only lymph node micrometastasis.Of the 131 patients with a negative LymphPET result,16 patients had LN-macro,and the NPV was 87.8%.After combined axillary imaging evaluation with ultrasound and LymphPET,100 patients were found to be both LymphPET and ultrasound negative,9 patients had LN-macro,and the NPV was 91%.Conclusions:LymphPET can be used to screen patients to potentially avoid SLNB,with an NPV>90%.The second stage of the SOAPET trial is ongoing to confirm the safety of omission of SLNB according to preoperational axillary evaluation integrating LymphPET. | Junjie Li Jingyi Cheng Guangyu Liu Yifeng Hou Genghong Di Benglong Yang Yizhou Jiang Liang Huang Feilin Qu Sheng Chen Yan Wang Keda Yu Zhimin Shao | 2022 | Cancer Biology & Medicine2022，19，7： | 1 |

| 17 | WaveNano:a signal-level nanopore base-caller via simultaneous prediction of nucleotide labels and move labels through bi-directional WaveNets显示文摘Background:The Oxford MinION nanopore sequencer is the recently appealing third-generation genome sequencing device that is portable and no larger than a cellphone.Despite the benefits of MiniON to sequence ultra-long reads in real-time,the high error rate of the existing base-calling methods,especially indels (insertions and deletions),prevents its use in a variety of applications. Methods:In this paper,we show that such indel errors are largely due to the segmentation process on the input electrical current signal from MiniON.All existing methods conduct segmentation and nucleotide label prediction in a sequential manner,in which the errors accumulated in the first step will irreversibly influence the final base-calling. We further show that the indel issue can be significantly reduced via accurate labeling of nueleotide and move labels directly from the raw signal,which can then be efficiently learned by a bi-directional WaveNet model simultaneously through feature sharing.Our bi-direetional WaveNet model with residual blocks and skip connections is able to capture the extremely long dependency in the raw signal.Taking the predicted move as the segmentation guidance,we employ the Viterbi decoding to obtain the final base-calling results from the smoothed nucleotide probability matrix. Results:Our proposed base-caller,WaveNano,achieves good performance on real MinION sequencing data from Lambda phage. Conclusions:The signal-level nanopore base-caller WaveNano can obtain higher base-caliing accuracy,and generate fewer insertions/deletions in the base-called sequences. | Sheng Wang Zhen Li Yizhou YU Xin Gao | 2018 | Frontiers of Electrical and Electronic Engineering in China2018，6，4： | 1 |
