2Recent progress and challenges of carbon materials for Zn-ion hybrid supercapacitors显示文摘Zinc-ion hybrid supercapacitors(ZHSCs)have garnered increasing attention as promising energy storage devices in recent years,as they combine the advantages of high-energy Zn-ion batteries and high-power supercapacitors.However,the development of ZHSCs is still in its infancy and there are many bottlenecks to overcome.In particular,the challenge induced by the limited ion adsorption capability of carbon-positive electrodes severely restricts the energy density of ZHSCs.Therefore,it has become a key issue to design novel carbon-positive electrodes that enable high energy density yet do not deteriorate the intrinsic power capability and long-term durability.This study focuses on recent achievements in synthesis,morphology,and electrochemical performance of various carbon materials applied in ZHSCs.The modification strategies to optimize their electrochemical performance are briefly summarized.In addition,current challenges and future opportunities in this field are also outlined.This review will be beneficial to provide an organized framework for the research systems of carbon-positive electrodes and develop novel ZHSCs with high energy density.Qiyu Liu Haozhe Zhang Jinhao Xie Xiaoqing Liu Xihong Lu 2020Carbon Energy2020,2,4:10
3Preparation of high-purity monodisperse silica microspheres by the sol-gel method coupled with polymerization-induced colloid aggregation显示文摘Ultra-pure mesoporous silica microspheres with good monodispersity were synthesized in two steps:nanometer-sized silica sol was produced by the sol-gel process,then micrometer-sized silica microspheres were synthesized by polymerization-induced colloid aggregation of the silica sol.The total metal content of the microspheres was extremely low,which eliminated the tailing of chromatographic peaks by chelating reagents.The pore structure of the silica microspheres could be controlled by altering the sol-gel conditions.The silica microsphere particle size could be adjusted by using different polymerizationinduced colloid aggregation conditions.Beibei Zhao Yan Zhang Tao Tang Fengyun Wang Tong Li Qiyu Lu 2015Particuology2015,13,5:7
4The mechanism of side reaction induced capacity fading of Ni-rich cathode materials for lithium ion batteries显示文摘Ni-rich cathode materials show great potential of applying in high-energy lithium ion batteries,but their inferior cycling stability hinders this process.Study on the electrode/electrolyte interfacial reaction is indispensable to understand the capacity failure mechanism of Ni-rich cathode materials and further address this issue.This work demonstrates the domain size effects on interfacial side reactions firstly,and further analyzes the inherent mechanism of side reaction induced capacity decay through comparing the interfacial behaviors before and after MgO coating.It has been determined that LiF deposition caused thicker SEI films may not increase the surface film resistance,while HF erosion induced surface phase transition will increase the charge transfer resistance,and the later plays the dominant factor to declined capacity of Ni-rich cathode materials.This work suggests strategies to suppress the capacity decay of layered cathode materials and provides a guidance for the domain size control to match the various applications under different current rates.Daozhong Hu Yuefeng Su Lai Chen Ning Li Liying Bao Yun Lu Qiyu Zhang Jing Wang Shi Chen Feng Wu 2021Journal of Energy Chemistry2021,30,7:5
5Stress accumulation in Ni-rich layered oxide cathodes:Origin,impact,and resolution显示文摘LiNi_(x)Co_(y)Mn_(z)O_(2)(NCM,x+y+z=1)is one of the most promising cathode candidates for high energy density lithium-ion batteries(LIBs).Due to the potential in enhancing energy density and cyclic life of LIBs,Ni-rich layered NCM(NCM,x≥0.6)have garnered significant research attention.However,improved specific capacity lead to severer expansion and shrinkage of layered lattice,accelerating the stress generation and accumulation even microcracks formation in NCM materials.The microcracks can promote the electrolyte permeation and decomposition,which can consequently reduce cyclic stabilities.Therefore,it is significant to provide an in-depth insight into the origin and impacts of stress accumulation,and the available modification strategies for the future development of NCM materials.In this review,we will first summarize the origin of stress accumulation in NCM materials.Next,we discuss the impact of stress accumulation.The electrolyte permeation along microcracks can enhance the extent of side reaction at the interface,trigger phase transformation and consequential capacity fading.To cushion the impact of stress accumulation,we will review five main strategies.Finally,concise perspectives to reduce stress accumulation and enhance particle strength in further works will be presented.Yuefeng Su Qiyu Zhang Lai Chen Liying Bao Yun Lu Shi Chen Feng Wu 2022Journal of Energy Chemistry2022,31,2:4
6Formulation optimization and in vitro antibacterial ability investigation of azithromycin loaded FDKP microspheres dry powder inhalation显示文摘Azithromycin loaded fumaryl diketopiperazine(FDKP)dry powder inhalation was designed and prepared for the treatment of community-acquired pneumonia.The solubility of FDKP and stability of azithromycin solution was investigated.Formulation of azithromycin loaded FDKP microparticle was investigated and optimized by the single factor experiment.High-pressure homogenization and spray drying conditions were also optimized to prepare the particles by spray drying azithromycin dissolved FDKP microparticle suspension at pH 4.5.The in vitro antibacterial efficiency and in vitro dispersion performance was also investigated to confirm the antibacterial efficiency,dispersion and deposition behavers.FDKP/azithromycin mass ratio(3:2)was the optimized formulation of azithromycin loaded FDKP microparticle with the maximal drug loading efficiency.High-pressure homogenization and spray drying conditions were also optimized.The in vitro antibacterial results indicated that only with the antibiotic concentration higher than mutant prevention concentration could totally inhibit the reproduction of bacteria.In vitro dispersion performance of azithromycin loaded FDKP microparticles(AZM@FDKP-MPs)also shows remarkable improvement of dispersion and deposition behavers of AZM.AZM@FDKP-MPs dry powder inhalation as a targeting delivery route has better potential for lung infection treatment.Qiyue Wang Liang Ge Lu Wang Ying Xu Si Miao Guiping Yu Yan Shen 2021Chinese Chemical Letters2021,32,3:2

8Study on the Resistance of Pseudoperonospora cubensis to Cymoxanil显示文摘[Objective] The paper was to clarify the sensitivity and resistance of Pseudoperonospora cubensis to cymoxanil.[Method] A total of 69 strains were collected from 13 major cucumber producing areas in eight provinces and cities of Guangdong, Hubei, Jiangsu, Shandong, Beijing, Liaoning, Jilin and Heilongjiang from 2012 to 2016, and their sensitivity and resistance to cymoxanil was determined using leaf disc floating method.[Result] The EC50 of cymoxanil to P. cubensis were 0.006 8-0.134 1 μg/mL and the average EC50 was 0.062 4 μg/mL. The sensitivity of P. cubensis to cymoxanil presented a single-peak curve, which was approximately normal distribution, and no strains with decreased sensitivity were found. The average EC50 (0.062 4 μg/mL) could be used as the sensitivity baseline of P. cubensis to cymoxanil. Among the 69 strains, 16 were low-resistance strains, accounting for 23.19% of the total strains;53 were sensitive strains, accounting for 76.81%, which were dominant populations;and no medium-resistance and high resistance strains were found. The resistance of P. cubensis to cymoxanil ranged from 0.11 to 2.15 times, and the average resistant level was 1.00 times.[Conclusion] Cymoxanil showed strong inhibitory effect against P. cubensis.Zhang Yanju He Ziwei Gao Jiyang Fu Lu Zhang Xingzhe Liu Qiyue Si Xiuyang 2019Plant Diseases and Pests2019,10,3:1
9Reappraise role of lymph node status in patterns of recurrence following curative resection of gastric adenocarcinoma显示文摘Objective: To examine the association between lymph node status and recurrence patterns in completely resected gastric adenocarcinoma.Methods: We retrospectively assessed 1,694 patients who underwent curative gastrectomy from January 2010 to August 2014. Patients stratified according to lymph node status and recurrence patterns among different subgroups were compared.Results: Of all, 517(30.5%) patients developed recurrent disease, and complete data of recurrence could be obtained in 493(95.4%) patients. For p^(N0) patients, the patterns of recurrence were different according to p T stage: locoregional recurrence was most common in patients with p T1-2 disease(57.1%), distant recurrence was most common in patients with p T3 disease(57.1%), and peritoneal recurrence was most common in patients with p T4 a disease(66.7%). For p^(N+) patients, distant metastasis was most common pattern irrespective of p T stage. The site-specific trend of recurrence showed that locoregional recurrence increased within 5 years in patients with p^(N0)-2 disease but plateaued 3 years after surgery in patients with p N3 disease. Time to recurrence was significantly longer for the p^(N0) patients compared with the p^(N+) patients(median: 25 vs. 16 months, P=0.001).Moreover, post-recurrence survival was significantly better for the p^(N0) patients than for the p^(N+) patients(median:12 vs. 6 months, P<0.001), especially in patients with non-peritoneal recurrence, late recurrence, single recurrence,and receipt of potential curative treatment.Conclusions: Among clinicopathologic factors, lymph node status is the most important factor associated with recurrence patterns after curative gastrectomy. Lymph node status may be used as an adjunct in clinical decisionmaking about postoperative therapeutic and follow-up strategies.Yihui Tang Jianxian Lin Junpeng Lin Jiabin Wang Jun Lu Qiyue Chen Longlong Caolj Mi Lin Ruhong Tu Changming Huang Ping Li Chaohui Zheng Jianwei Xie 2021Chinese Journal of Cancer Research2021,33,3:1

11General image classification method based on semi-supervised generative adversarial networks显示文摘Generative adversarial networks(GANs) have become a competitive method among computer vision tasks. There have been many studies devoted to utilizing generative network to do generative tasks, such as images synthesis. In this paper, a semi-supervised learning scheme is incorporated with generative adversarial network on image classification tasks to improve the image classification accuracy. Two applications of GANs are mainly focused on: semi-supervised learning and generation of images which can be as real as possible. The whole process is divided into two sections. First, only a small part of the dataset is utilized as labeled training data. And then a huge amount of samples generated from the generator is added into the training samples to improve the generalization of the discriminator. Through the semi-supervised learning scheme, full use of the unlabeled data is made which may contain potential information. Thus, the classification accuracy of the discriminator can be improved. Experimental results demonstrate the improvement of the classification accuracy of discriminator among different datasets, such as MNIST, CIFAR-10.苏磊 Xu Xiangyi Lu Qiyu Zhang Wancai 2019High Technology Letters2019,25,1:1

14A broadly neutralizing antibody inhibits SARS-CoV-2 variants through a novel mechanism of disrupting spike trimer integrity显示文摘Dear Editor,Since the start of the COVID-19 pandemic,thousands of neutralizing antibodies(NAbs)targeting different epitopes of the spike protein have been identifed and characterized.1-3 However,the emergence of the Omicron variant and its subvariants has raised global concern due to their resistance to most reported monoclonal antibodies and dramatically decreases the immune effcacy of current Vaccines.4sA newly emerging,subvariant XBB.1.16 that is rapidly disseminating on a global scale has been associated with a previously unreported symptom of red or pink eye.Compared to XBB.1.5,XBB.1.16 harbors two additional mutations,E180V and K478R,which are hypothesized to confer enhanced transmissibility and antigenic escape.?Yunping Ma Qiyu Mao Yingdan Wang Zhaoyong Zhang Jiali Chen Aihua Hao Palizhati Rehati Yanqun Wang Yumei Wen Lu Lu Zhenguo Chen Jincun Zhao Fan Wu Lei Sun Jinghe Huang 2023Cell Research2023,33,12:0
15Enhanced Corrosion Resistance and Biofilm Inhibition of Functionally Graded TC4/TC4-5Cu Fabricated by Selective Laser Melting against Streptococcus mutans显示文摘Ti-6Al-4V(TC4)used in dentistry and orthopedics as implant biomaterial faces the risk of microbiologically influenced corrosion(MIC)owing to the residence of diverse oral microorganisms.Hereinto,Streptococcus mutans is a critical pathogenic microorganism that causes dental caries.This work investigated the corrosive effects of S.mutans on TC4 and functional gradient TC4/TC4-5Cu coupons fabricated by selective laser melting(SLM)through various electrochemical measurements,surface examination,observation of biofilm and corrosion analysis.The results indicated that the Cu-bearing alloy showed an inhibitory effect on the biofilms due to the release of Cu element,thereby reducing the corrosion rate of MIC.The corrosion current density(icorr)of TC4(11.7±0.8)nA cm−2 is higher than that of TC4/TC4-5Cu(7.4±0.4)nA cm−2 in the presence of S.mutans,while the maximum pit depth of TC4 is 1.6 times that of TC4/TC4-5Cu.Therefore,metal modification through Cu alloying is an effective strategy to improve the MIC resistance.Xing Zhou Qiyue Zhang Jiarui Lu Ying Zheng Lin Wu Dake Xu Xue Zhang Qiang Wang 2023Acta Metallurgica Sinica(English Letters)2023,36,12:0
