1A review:Photonics devices,architectures,and algorithms for optical neural computing显示文摘The explosive growth of data and information has motivated various emerging non-von Neumann computational approaches in the More-than-Moore era.Photonics neuromorphic computing has attracted lots of attention due to the fascinating advantages such as high speed,wide bandwidth,and massive parallelism.Here,we offer a review on the optical neural computing in our research groups at the device and system levels.The photonics neuron and photonics synapse plasticity are presented.In addition,we introduce several optical neural computing architectures and algorithms including photonic spiking neural network,photonic convolutional neural network,photonic matrix computation,photonic reservoir computing,and photonic reinforcement learning.Finally,we summarize the major challenges faced by photonic neuromorphic computing,and propose promising solutions and perspectives.Shuiying Xiang Yanan Han Ziwei Song Xingxing Guo Yahui Zhang Zhenxing Ren Suhong Wang Yuanting Ma Weiwen Zou Bowen Ma Shaofu Xu Jianji Dong Hailong Zhou Quansheng Ren Tao Deng Yan Liu Genquan Han Yue Hao 2021Journal of Semiconductors2021,42,2:7
2Multi-functional polyethersulfone nanofibrous membranes with ultra-high adsorption capacity and ultra-fast removal rates for dyes and bacteria显示文摘The adsorption technology has been widely applied in water remediation for contamination removal of dyes and bacteria,by virtue of the advantages of adsorption technology including high efficiency,energy conservation and ease of operation.Simultaneous removal of dyes and bacteria has been realized by some reported materials,but to achieve satisfactory adsorption amounts and rates remain an unmet goal for decades.Herein,a poly(methacrylatoethyl trimethyl ammonium chloride-co-methyl methacrylate)copolymer was synthesized,and then blended with polyethersulfone for the fabrication of nanofibrous membranes via electrospinning for the use of fast and massive removal of dyes and bacteria.Owing to the introduction of abundant quaternary ammonium groups,the maximum adsorption amount for methyl orange was up to 909.8 mg g^(-1).In addition,the modified nanofibrous membranes showed good recyclability,broad applications in severe environments,selective adsorption ability,and excellent dynamic removal performance.Especially,thanks to the abundant functional groups,the membranes showed fast adsorption ability for bacteria through electrostatic interaction.It should be noted that the clearance ratio for Staphylococcus aureus or Escherichia coli by 6 min of static adsorption could reach 93%or 90%for each.Additionally,dynamic removal ratio via filtration with the nanofibrous membranes could reach 99.7%for Staphylococcus aureus or 98.7%for Escherichia coli in 90 s.Therefore,the proposed approach towards the quaternary ammonium modified polyethersulfone nanofibrous membranes creates a new route for ultra-high adsorption capacity and ultra-fast removal rates for dyes and bacteria in water remediation.Jianxu Bao Hang Li Yuanting Xu Shengqiu Chen Zhoujun Wang Chunji Jiang Huilin Li Zhiwei Wei Shudong Sun Weifeng Zhao Changsheng Zhao 2021Journal of Materials Science & Technology2021,,19:4
3A single mutation underlying phenotypic convergence for hypoxia adaptation on the Qinghai-Tibetan Plateau显示文摘Dear Editor,The Qinghai-Tibet Plateau(QTP)is the highest and largest plateau in the world;its altitude exceeds 4500 m on average,posing great physiological challenges such as severe hypoxia for endemic wild mammals on the plateau.1 To cope with such a harsh environment,the phylogenetically distant QTP endemic mammals have independently evolved similar morphological and physiological traits.Donqming Xu Cuiping Yang Qiushuo Shen Shengkai Pan Zhen Liu Tongzuo Zhang Xin Zhou Menglong Lei Peng Chen Hui Yang Tao Zhang Yuanting Guo Xiangjiang Zhan Yongbin Chen Peng Shi 2021Cell Research2021,31,9:1
4“1+1>2”:Highly efficient removal of organic pollutants by composite nanofibrous membrane based on the synergistic effect of adsorption and photocatalysis显示文摘Adsorption and photocatalysis are regarded as two desirable technologies for wastewater remediation,but are still unsatisfactory in removal effect,eco-friendly regeneration and facile reusability.In this study,we developed a composite nanofibrous membrane material with excellent removal performance for organic pollutants based on synergistic adsorption and photocatalysis.A novel boron-doped,nitrogen-deficient graphitic carbon nitride(B-C3N4)photocatalyst as well as an amphiphilic copolymer of methyl methacrylate and acrylic acid(p(MMA-AA))were synthesized respectively,and then used to modify polyethersulfone for the fabrication of composite nanofibrous membrane with improved hydrophilicity,negativelycharge property and enhanced visible light response simultaneously.Subsequently,the synergistic effect of adsorption and photocatalytic degradation for organic pollutants were identified especially and resulted in an excellent removal efficiency even superior to the combination of adsorption and photocatalytic degradation,which could be called a“1+1>2”effect.In addition,the regeneration and reusability,the purification ability for multicomponent wastewater,and the photocatalytic mechanism,were investigated and discussed systematically.In this work,we not only prepared the nanofibrous membrane with synergistic effect of adsorption and photocatalysis,but also provided a versatile approach to design dualfunctional support material to ensure the practical applications of powdery photocatalyst in wastewater treatment.Yuanting Xu Wanting Lin Dandan Yuan Shifan Chen Fang Li Yanping Long Chao He Weifeng Zhao Changsheng Zhao 2022Journal of Materials Science & Technology2022,,29:1

6Preparing amphiphilic acidic zeolite via chemically coating alkylamine显示文摘Amphiphilic ODA/HY and ODA/ Hβ zeolites have been prepared via chemically coating octadecylamine (ODA) with alcohol as solvent. IR and titrimetric results indicate that ODA molecules are chemisorbed on the acidic sites in zeolite, showing the higher thermostability and alcohol-resistance. These am- phiphilic zeolites contain both the hydrophobic and hydrophilic groups, orient at the liquid-liquid phase-boundary in both cyclohexane/water and water/carbon tetrachloride systems, and exhibit the potential to be used in the phase-boundary catalysis and adsorption. No by-products with strong acid- ity are formed in this approach, therefore, it can be used to prepare amphiphilic acidic zeolites with low Si/Al ratio.SUN RuiQin CHUN Yuant MA BingLi LI Ping DONG JiaLu XU QinHua 2007Chinese Science Bulletin2007,52,17:1
7Carbon-supported high-entropy Co-Zn-Cd-Cu-Mn sulfide nanoarrays promise high-performance overall water splitting显示文摘Transition metal sulfides with homogeneous multi-metallic elements promise high catalytic performance for water electrolysis owing to the unique structure and highly tailorable electrochemical property.Most existing synthetic routes require high temperature to ensure the uniform mixing of various elements,making the synthesis highly challenging.Here,for the first-time novel carbon fiber supported high-entropy Co-Zn-Cd-Cu-Mn sulfide(CoZnCdCuMnS@CF)nanoarrays are fabricated by the mild cation exchange strategy.Benefiting from the synergistic effect among multiple metals and the strong interfacial bonding between high-entropy Co-Zn-Cd-Cu-Mn sulfide nanoarrays and the carbon fiber support,CoZnCdCuMnS@CF exhibits superior catalytic activity and stability toward overall water splitting in alkaline medium.Impressively,CoZnCdCuMnS@CF only needs low overpotentials of 173 and 220 mV to reach the current density of 10 mA•cm^(−2),with excellent durability for over 70 and 113 h for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)respectively.More importantly,the bifunctional electrode(CoZnCdCuMnS@CF||CoZnCdCuMnS@CF)for overall water splitting can deliver a small cell voltage of 1.63 V to afford 10 mA•cm^(−2) and exhibit outstanding stability of negligible decay after 73 h continuous operation.This work provides a viable synthesis route toward advanced high-entropy materials with great potential applications.Yuanting Lei Lili Zhang Wenjing Xu Chengli Xiong Wenxing Chen Xu Xiang Bing Zhang Huishan Shang 2022Nano Research2022,15,7:0
8Clinical features and outcome of 15 patients with recurrent endometrial cancer or atypical endometrial hyperplasia received primary fertility-sparing therapy followed by hysterectomy显示文摘Objective To investigate the clinical features and outcome of recurrent endometrial cancer(EC)or atypical endometrial hyperplasia(AEH)patients who underwent hysterectomy after fertility-sparing therapy.Methods Clinical data was retrospectively collected for 15 recurrent endometrial cancer or atypical endometrial hyperplasia patients who underwent hysterectomy in six hospitals from 2003 to 2019.According to the indicators of hysterectomy,patients were divided into four groups:7 patients who underwent direct hyesterectomy after the first relapse,4 due to re-treatment failure,1 after full term live birth,and 3 because of multiple recurrence.Clinical coexisting conditions,regimen and outcome of fertility-sparing therapy,pre-and post-operative pathological results,and prognosis were analyzed.Results(1)Fertility-spraring treatment was given to a total of 15 eligible patients,including 6 with EC and 9 with AEH.Median time interval from remission to recurrence was 12 months(range 3–92).Oral progestin-based medicine was the main fertility-sparing therapy in both primary treatment and re-treatment after recurrence.Six(6/8)patients received progestin combined with gonadotrophin releasing hormone agonist or metformin in three re-treatment groups.(2)Nine patients underwent hysterectomy and 6 staging surgery.Three patients had pathological upgrade after surgery.Five(5/10)EC patients had superficial myometrial invasion in postoperative pathology.All patients showed no evidence of disease in the median follow-up of 17 months(range 3–118).(3)Among seven patients who failed to re-treatment and had multiple recurrence,six were overweight/obesity and six had insulin resistance.Two of these patients had synchronous ovarian cancer in the postoperative pathology.Conclusion For the patients with recurrent EC or AEH after primary fertility-sparing therapy,overweight/obesity and insulin resistance might be the risk factors for re-treatment failure.Hysterectomy is recommended when patients had re-treatment failure or multiple recurrence;and generally the prognosis is favorable.Yuanting Li Yiqin Wang Yijiao He Rong Zhou Huiru Tang Lijiang Xu Mian He Weili Li Chunlin Chen Weifeng Zhang Jianliu Wang 2021Gynecology and Obstetrics Clinical Medicine2021,1,1:0
9Oxalic Acid Promoted Hydrolysis of Sodium Borohydride for Transition Metal Free Hydrogen Generation显示文摘We reported an inexpensive and high-efficiency hydrogen generation method from NaBH4 hydrolysis promoted by oxalic acid.NaBH4 and H2C2O4 were premixed and hydrogen generation was initiated by adding water into the solid mixture.H2C2O4 was selected as the acid promotor due to its solid state and low mass per proton.The effect of reactant ratio on the hydrogen yield and hydrogen storage density was investigated.With optimized reactant ratio,high gravimetric hydrogen storage up to 4.4wt%based on all the reactants can be achieved with excellent hydrogen generation kinetics.PENG Yuanting ZENG Hui SHI Yu XU Jinrong 谢镭 陈均 ZHENG Jie LI Xingguo 2020Journal of Wuhan University of Technology(Materials Science)2020,35,6:0

11Toxicity effects of disinfection byproduct chloroacetic acid to Microcystis aeruginosa: Cytotoxicity and mechanisms显示文摘Chlorine-based disinfectants are widely used for disinfection in wastewater treatment.The mechanism of the effects of chlorinated disinfection by-products on cyanobacteria was unclear.Herein,the physiological effects of chloroacetic acid(CAA)on Microcystis aeruginosa(M.aeruginosa),including acute toxicity,oxidative stress,apoptosis,production of microcystin-LR(MC-LR),and the microcystin transportation-related gene mcyH transcript abundance have been investigated.CAA exposure resulted in a significant change in the cell ultrastructure,including thylakoid damage,disappearance of nucleoid,production of gas vacuoles,increase in starch granule,accumulation of lipid droplets,and disruption of cytoplasm membranes.Meanwhile,the apoptosis rate of M.aeruginosa increased with CAA concentration.The production of MC-LR was affected by CAA,and the transcript abundance of mcyH decreased.Our results suggested that CAA poses acute toxicity to M.aeruginosa,and it could cause oxidative damage,stimulate MC-LR production,and damage cell ultrastructure.This study may provide information about the minimum concentration of CAA in the water environment,which is safe for aquatic organisms,especially during the global coronavirus disease 2019 pandemic period.Jing Ye Jiawei Ni Fuxiang Tian Xiyan Ji Meifang Hou Yuanting Li Lei Yang Runxiang Wang Wenwu Xu Liang Meng 2023Journal of Environmental Sciences2023,,7:0
12Induction of multiple subroutines of regulated necrosis in murine macrophages by natural BH3-mimetic gossypol显示文摘Macrophages are critical sentinel cells armed with multiple regulated necrosis pathways,including pyroptosis,apoptosis followed by secondary necrosis,and necroptosis,and are poised to undergo distinct form(s)of necrosis for tackling dangers of pathogenic infection or toxic exposure.The natural BH3-mimetic gossypol is a toxic phytochemical that can induce apoptosis and/or pyroptotic-like cell death,but what exact forms of regulated necrosis are induced remains largely unknown.Here we demonstrated that gossypol induces pyroptotic-like cell death in both unprimed and lipopolysaccharide-primed mouse bone marrow-derived macrophages(BMDMs),as evidenced by membrane swelling and ballooning accompanied by propidium iodide incorporation and lactic acid dehydrogenase release.Notably,gossypol simultaneously induces the activation of both pyroptotic and apoptotic(followed by secondary necrosis)pathways but only weakly activates the necroptosis pathway.Unexpectedly,gossypol-induced necrosis is independent of nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3(NLRP3)inflammasome,as neither inhibitor for the NLRP3 pathway nor NLRP3 deficiency protects the macrophages from the necrosis.Furthermore,necrotic inhibitors or even pan-caspase inhibitor alone does not or only partly inhibit such necrosis.Instead,a combination of inhibitors composed of pan-caspase inhibitor IDN-6556,RIPK3 inhibitor GSK′872 and NADPH oxidase inhibitor GKT137831 not only markedly inhibits the necrosis,with all apoptotic and pyroptotic pathways being blocked,but also attenuates gossypol-induced peritonitis in mice.Lastly,the activation of the NLRP3 pathway and apoptotic caspase-3 appears to be independent of each other.Collectively,gossypol simultaneously induces the activation of multiple subroutines of regulated necrosis in macrophages depending on both apoptotic and inflammatory caspases.Meiyan Zhong Yuanting Huang Bo Zeng Lihui Xu Chunsu Zhong Jiahao Qiu Xunjia Ye Mingye Chen Bo Hu Dongyun Ouyang Xianhui He 2022Acta Biochimica et Biophysica Sinica2022,54,1:0

14Isolable Bis-BN-Based Analogues of Müller's Hydrocarbon显示文摘Müller's hydrocarbon and its analogues are classical examples of Kekulé diradicaloids and have gained great attention.However,because of their high reactivities,their isolation and structural characterizations are still challenging.Herein,we report the isolation of two bis-BN-based analogues of Müller's hydrocarbon (1 and 2) as crystalline solids in moderate yields.Experimental results and theoretical studies demonstrated that compound 1 possessing the terminal 1,3,2-diazaboryl groups is an open-shell singlet diradicaloid,which is in contrast to the closed-shell singlet ground states of the bis-BN-based analogues of Thiele's and Chichibabin's hydrocarbons with the same terminal groups,illustrating the strong influence of the central linkers on the ground state.Additionally,the replacement of the terminal 1,3,2-diazaboryl groups in 1 with the bis(2,4,6-triisopropylphenyl)boryl groups affords 2 with higher diradical character and a smaller singlet-triplet energy gap.Sha Xu Zhuofeng Xie Yuyang Dai Xiaona Liu Qidi Bao Chunmeng Liu Yuanting Su 2023Chinese Journal of Chemistry2023,41,23:0
