| 1 | NbN superconducting nanowire single photon detector with efficiency over 90% at 1550 nm wavelength operational at compact cryocooler temperature显示文摘The rapid development of superconducting nanowire single-photon detectors over the past decade has led to numerous advances in quantum information technology. The record for the best system detection efficiency at an incident photon wavelength of 1550 nm is 93%. This performance was attained from a superconducting nanowire single-photon detector made of amorphous WSi; such detectors are usually operated at sub-Kelvin temperatures. In this study, we first demonstrate superconducting nanowire single-photon detectors made of polycrystalline NbN with system detection efficiency of 90.2% for 1550-nm-wavelength photons at2.1 K, accessible with a compact cryocooler. The system detection efficiency saturated at 92.1% when the temperature was lowered to 1.8 K. We expect the results lighten the practical and high performance superconducting nanowire single-photon detectors to quantum information and other high-end applications. | WeiJun Zhang LiXing You Hao Li Jia Huang ChaoLin Lv Lu Zhang XiaoYu Liu JunJie Wu Zhen Wang XiaoMing Xie | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，12： | 9 |
| 2 | Towards high-performance lithium metal anodes via the modification of solid electrolyte interphases显示文摘Li metal has been regarded as one of the most promising anodes for high-energy-density storage systems due to its high theoretical capacity and lowest electrochemical potential.Unfortunately,an unstable and non-uniform solid electrolyte interphase(SEI)deriving from the spontaneous reaction between Li metal anode and electrolyte causes uneven Li deposition,resulting in the growth of Li dendrites and low Coulombic efficiency,which have greatly hindered the practical application of Li metal batteries.Thus,the construction of a stable SEI is an effective approach to suppress the growth of Li dendrites and enhance the electrochemical performances of Li metal anode.In this review,we firstly introduce the formation process of inferior SEI of Li metal anode and the corresponding challenges caused by the unstable SEI.Next,recent progresses to modify SEI layer through the regulation of electrolyte compositions and exsitu protective coating are summarized.Finally,the remained issues,challenges,and perspectives are also proposed on the basis of current research status and progress. | Zhen Hou Jiaolong Zhang Wenhui Wang Qianwen Chen Baohua Li Chaolin Li | 2020 | Journal of Energy Chemistry2020，29，6： | 8 |
| 3 | Additive manufacturing of steel–copper functionally graded material with ultrahigh bonding strength显示文摘Additive manufacturing enables processing of functionally graded materials(FGMs)with flexible spatial design and high bonding strength.A steel-copper FGM with high interfacial strength was developed using laser powder bed fusion(LPBF).The effect of laser process parameters on interfacial defects was evaluated by X-ray tomography,which indicates a low porosity level of 0.042%therein.Gradient/fine dendritic grains in the interface are incited by high cooling rates,which facilitates interface strengthening.Multiple mechanical tests evaluate the bonding reliability of interface;and the fatigue tests further substantiate the ultrahigh bonding strength in FGMs,which is superior to traditional manufacturing methods.Mechanisms of the high interfacial bond strength were also discussed. | Chaolin Tan Youxiang Chew Guijun Bi Di Wang Wenyou Ma Yongqiang Yang Kesong Zhou | 2021 | Journal of Materials Science & Technology2021，，13： | 7 |

| 6 | Digital medical education empowered by intelligent fabric space显示文摘Medical education plays an important role in promoting the development of global medical science.Nevertheless,the intrinsic gap existing between institutional medical teaching and practical clinical tasks causes low education efficiency and students’weak initiative.Recent developments of sensing fabric and embedded computing,along with the advances in artificial intelligence(AI)and digital twin technology are paving the way for the transformation of medical research towards digitization.In this work,we present an intelligent fabric space based on novel functional fabric materials and digital twin networking enabled by 5G and internet of things(IoT)technologies.In this space,medical students can learn knowledge with collaborative mapping of the digital and real world,cyber-physical interaction and real-time tactile feedback.And the proposed service system will evaluate and feedback students’operational behaviors to improve their experimental skills.We provide four typical applications of intelligent fabric space for medical education,including medical education training,health and behavior tracking,operation playback and reproduction,as well as medical knowledge popularization.The proposed intelligent fabric space has the potential to promote innovative technologies for training cutting-edge medical students by effective and efficient ways. | Min Chen Rui Wang Rui Wang Yingting Zhou Zicheng He Xiaojuan Liu Muyao He Jiaxi Wang Chaolin Huang Huamin Zhou Ping Hong Chong Hou Ning Zhou Dingyu Zhang Guangming Tao | 2022 | National Science Open2022，1，1： | 2 |
| 7 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |

| 9 | Nest-site Use by the Chinese Alligator (Alligator sinensis) in the Gaojingmiao Breeding Farm,Anhui,China显示文摘Nest-site and nesting material used by the Chinese alligator(Alligator sinensis) was studied at the Gaojingmiao Breeding Farm, Langxi County,Anhui, China from May to September 2009. In this study, artificial nesting materials were placed in 43 potential nesting sites before the nesting season, 11 of which were used. Additionally, eight nests were built at natural sites without artificial nesting materials provided. Seven environmental variables were measured at each nest site: distance from water, height from water surface, sunlight duration, nearest bank slope, nest site slope, vegetation coverage and concealment. Statistical analyses indicated that concealment was significantly different between used and unused nest sites, with concealment being significantly correlated to the use of materialsplaced sites. In comparing the nests at artificial vs. natural sites, only the nearest bank slope differed significantly. Further, principal component analysis of natural nests indicated that the duration of nest exposure to sunlight and vegetation coverage were more influential than the other factors studied. | Jianjun WANG Xiaobing WU Dawei TIAN Jialong ZHU Renping WANG Chaolin WANG | 2011 | Asian Herpetological Research2011，2，1： | 1 |
| 10 | Recent advances in modification strategies of silicon-based lithiumion batteries显示文摘As potential alternatives to graphite,silicon(Si)and silicon oxides(SiO_(x))received a lot of attention as anode materials for lithiumion batteries owing to their relatively low working potentials,high theoretical specific capacities,and abundant resources.However,the commercialization of Si-based anodes is greatly hindered by their massive volume expansion,low conductivity,unstable solid electrolyte interface(SEI),and low initial Coulombic efficiency(ICE).Continuous endeavors have been devoted to overcoming these challenges to achieve practical usage.This review is centered on the major challenges and latest developments in the modification strategies of Si-based anodes,including structure optimization,surface/interface regulation,novel binders,and innovative design of electrolyte.Finally,outlooks and perspectives of Si-based anodes for future development are presented. | Wenlei Wang Yu Wang Lixuan Yuan Chaolin You Junwei Wu Lili Liu Jilei Ye Yunling Wu Lijun Fu | 2023 | Nano Research2023，16，3： | 1 |

| 13 | Removal of gaseous volatile organic compounds via vacuum ultraviolet photodegradation: Review and prospect显示文摘Volatile organic compounds(VOCs) have attracted much attention for decades as they are the precursors of photochemical smog and are harmful to the environment and human health. Vacuum ultraviolet(VUV) photodegradation is a simple and effective method to decompose VOCs (ranging from tens to hundreds of ppmV) without additional oxidants or catalysts in the air at atmospheric pressure. In this paper, we review the research progress of VOCs removal via VUV photodegradation. The fundamentals are outlined and the key operation factors for VOCs degradation, such as humidity, oxygen content, VOCs initial concentration, light intensity, and flow rate, are discussed. VUV photodegradation of VOCs mixture is elucidated. The application of VUV photodegradation in combination with ozoneassisted catalytic oxidation(OZCO) and photocatalytic oxidation(PCO) systems, and as the pre-treatment technique for biological purification are illustrated. Based on the summary,we propose the challenges of VUV photodegradation and perspectives for its future development. | Xue Sun Chaolin Li Boping Yu Jingwen Wang Wenhui Wang | 2023 | Journal of Environmental Sciences2023，，3： | 1 |

| 15 | Mutual impact of true triaxial stress, borehole orientation and bedding inclination on laboratory hydraulic fracturing of Lushan shale显示文摘Unconventional resources like shale gas has been the focus of intense research and development for two decades. Apart from intrinsic geologic factors that control the gas shale productivity (e.g. organic matter content, bedding planes, natural fractures, porosity and stress regime among others), external factors like wellbore orientation and stimulation design play a role. In this study, we present a series of true triaxial hydraulic fracturing experiments conducted on Lushan shale to investigate the interplay of internal factors (bedding, natural fractures and in situ stress) and external factors (wellbore orientation) on the growth process of fracture networks in cubic specimens of 200 mm in length. We observe relatively low breakdown pressure and fracture propagation pressure as the wellbore orientation and/or the maximum in situ stress is subparallel to the shale bedding plane. The wellbore orientation has a more prominent effect on the breakdown pressure, but its effect is tapered with increasing angle of bedding inclination. The shale breakdown is followed by an abrupt response in sample displacement, which reflects the stimulated fracture volume. Based on fluid tracer analysis, the morphology of hydraulic fractures (HF) is divided into four categories. Among the categories, activation of bedding planes (bedding failure, BF) and natural fractures (NF) significantly increase bifurcation and fractured areas. Under the same stress regime, a horizontal wellbore is more favorable to enhance the complexity of hydraulic fracture networks. This is attributed to the relatively large surface area in contact with the bedding plane for the horizontal borehole compared to the case with a vertical wellbore. These findings provide important references for hydraulic fracturing design in shale reservoirs. | Yongfa Zhang Anfa Long Yu Zhao Arno Zang Chaolin Wang | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023，15，12： | 1 |

| 17 | Impact of corticosteroids on initiation and half-year durability of humoral response in COVID-19 survivors显示文摘Background:The impact of corticosteroids on humoral responses in coronavirus disease 2019(COVID-19)sur-vivors during the acute phase and subsequent 6-month period remains unknown.This study aimed to determine how the use of corticosteroids influences the initiation and duration of humoral responses in COVID-19 survivors 6 months after infection onset.Methods:We used kinetic antibody data from the lopinavir-ritonavir trial conducted at Jin Yin-Tan Hospital in January 2020,which involved adults hospitalized with severe COVID-19(LOTUS,ChiCTR2000029308).Anti-body samples were collected from 192 patients during hospitalization,and kinetic antibodies were monitored at all available time points after recruitment.Additionally,plasma samples were collected from 101 COVID-19 survivors for comprehensive humoral immune measurement at the half-year follow-up visit.The main focus was comparing the humoral responses between patients treated with systemic corticosteroid therapy and the non-corticosteroid group.Results:From illness onset to day 30,the median antibody titre areas under the receiver operating characteristic curve(AUCs)of nucleoprotein(N),spike protein(S),and receptor-binding domain(RBD)immunoglobulin G(IgG)were significantly lower in the corticosteroids group.The AUCs of N-,S-,and RBD-IgM as well as neutralizing antibodies(NAbs)were numerically lower in the corticosteroids group compared with the non-corticosteroid group.However,peak titres of N,S,RBD-IgM and-IgG and NAbs were not influenced by corticosteroids.During 6-month follow-up,we observed a delayed decline for most binding antibodies,except N-IgM(��−0.05,95%CI[−0.10,0.00])in the corticosteroids group,though not reaching statistical significance.No significant difference was observed for NAbs.However,for the half-year seropositive rate,corticosteroids significantly accelerated the decay of IgA and IgM but made no difference to N-,S-,and RBD-IgG or NAbs.Additionally,corticosteroids group showed a trend towards delayed viral clearance compared with the non-corticosteroid group,but the results were not statistically significant(adjusted hazard ratio 0.71,95%CI 0.50-1.00;P=0.0508).Conclusion:Our findings suggested that corticosteroid therapy was associated with impaired initiation of the antibody response but this did not compromise the peak titres of binding and neutralizing antibodies.Throughout the decay phase,from the acute phase to the half-year follow-up visit,short-term and low-dose corticosteroids did not significantly affect humoral responses,except for accelerating the waning of short-lived antibodies. | Yeming Wang Li Guo Guohui Fan Yang Han Qiao Zhang Lili Ren Hui Zhang Geng Wang Xueyang Zhang Tingxuan Huang Weiyang Wang Lan Chen Lixue Huang Xiaoying Gu Xinming Wang Jingchuan Zhong Ying Wang Hui Li Jiapei Yu Zhibo Liu Chaolin Huang Bin Cao Jianwei Wang | 2024 | Chinese Medical Journal Pulmonary and Critical Care Medicine2024，2，1： | 0 |
| 18 | Coupling functional anodes with natural air-diffused cathodes enables highly efficient hydrogen peroxide electrosynthesis显示文摘Electrosynthesis of hydrogen peroxide(H_(2)O_(2))is a decentralized production method with excellent application prospects.Coupling anodes with cathodes can achieve highly efficient electrosynthesis of hydrogen peroxide.In this study,we prepared an anode for H_(2)O_(2) electrosynthesis via the two-electron water oxidation reaction(2e-WOR)by modifying carbon fiber paper with self-assembling monolayers.In addition,a natural air-diffused cathode loaded with polytetrafluoroethylene/carbon black using carbon cloth as substrate was prepared to combine with the modified anode to produce H_(2)O_(2) simultaneously.The total current efficiency of the anode and cathode reached 152.9%,and the H_(2)O_(2) production rate was as high as 38μmol/min at 2.8 V vs.reversible hydrogen electrodes(RHE)in a Nafion 117 membrane-separated electrolyzer.This work reported a novel carbon-based 2e-WOR catalyst and laid a theoretical foundation for the simultaneous electrosynthesis of H_(2)O_(2) with an anode and cathode. | Chen LING Aiping LIANG Chaolin LI Wenhui WANG | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，4： | 0 |
| 19 | Study on damage-stress loss coupling model of rock and prestressed anchor cable in dry-wet environment显示文摘The loss of anchoring force is one of the problems to be solved urgently.The anchorage loss is a key factor causing the failure of anchoring engineering,so it is crucial to study the time-dependent variation of anchoring force.Alternating dry and wet(D-W)conditions have a significant effect on deformation of rock.The anchoring system is composed of anchoring components and rock mass,and thus rock deformation has a significant impact on the loss of anchoring force.Quantifying rock deformation under the effects of D-W cycles is a prerequisite to understanding the factors that influence loss of anchoring force in anchor bolts.In this study,we designed an anchoring device that enabled real-time monitoring of the variation in strain during D-W periods and rock testing.Nuclear magnetic resonance(NMR)measurements showed that under D-W conditions,the increment in porosity was smaller for prestressed rock than unstressed rock.The trends of prestress loss and strain variation are consistent,which can be divided into three characteristic intervals:rapid attenuation stage,slow attenuation stage and relatively stable stage.At the same stress level,the rate of stress loss and strain for the soaking specimen was the highest,while that of the dried specimen was the lowest.In the same D-W cycling conditions,the greater the prestress,the smaller the strain loss rate of the rock,especially under soaking conditions.The characteristics of pore structure and physical mechanical parameters indicated that prestress could effectively suppress damage caused by erosion related to D-W cycles.The study reveals the fluctuation behavior of rock strain and prestress loss under D-W conditions,providing a reference for effectively controlling anchoring loss and ideas for inventing new anchoring components. | Yu Zhao Huasu Wang Jing Bi Zhijun Wu Chaolin Wang Jiabao Ma | 2023 | International Journal of Mining Science and Technology2023，33，12： | 0 |
| 20 | Characteristics of coal resources in China and statistical analysis and preventive measures for coal mine accidents显示文摘In the process of green and smart mine construction under the context of carbon neutrality,China's coal safety situation has been continuously improved in recent years.In order to recognize the development of coal production in China and prepare for future monitoring and prevention of safety incidents,this study mainly elaborated on the basic situation of coal resources and national mining accidents over the past five years(2017-2021),from four dimensions(accident level,type,region,and time),and then proposed the preventive measures based on accident statistical laws.The results show that the storage of coal resources has obvious geographic characteristics,mainly concentrated in the Midwest,with coal resources in Shanxi and Shaanxi accounting for about 49.4%.The proportion of coal consumption has dropped from 70.2%to 56%between 2011 and 2021,but still accounts for more than half of the all.Meanwhile,the accident-prone areas are positively correlated with the amount of coal production.Among different levels of coal mine accidents,general accidents had the highest number of accidents and deaths,with 692 accidents and 783 deaths,accounting for 87.6%and 54.64%respectively.The frequency of roof,gas,and transportation accidents is relatively high,and the number of single fatalities caused by gas accidents is the largest,about 4.18.In terms of geographical distribution of accidents,the safety situation in Shanxi Province is the most severe.From the time distribution of coal mine accidents,the accidents mainly occurred in July and August,and rarely occurred in February and December.Finally,the'4+4'safety management model is proposed,combining the statistical results with coal production in China.Based on the existing health and safety management systems,the manage-ments are divided into four sub-categories,and more specific measures are suggested. | Chaolin Zhang Peizhong Wang Enyuan Wang Dapeng Chen Chao Li | 2023 | International Journal of Coal Science & Technology2023，10，2： | 0 |
