| 1 | Single-cell analysis reveals bronchoalveolar epithelial dysfunction in COVID-19 patients显示文摘Dear Editor,In 2019,a zoonotic coronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was identified as the causative agent of Coronavirus Disease 2019(COVID-19).As of 8 June 2020,the World Health Organization(WHO)has reported 6,912,751 globally confirmed cases with 400,469 deaths.Although generally causes mild disease,SARS-CoV-2 infection can result in serious outcomes,including acute lung injury(ALI)and acute respiratory distress syndrome(ARDS),the leading cause of mortality in patients with comorbidities.Recent autopsy studies of COVID-19 patients revealed mononuclear infiltration and excessive production of mucus in the infected lung,especially in the damaged small airways and alveoli(Bian and Team,2020;Liu et al.,2020). | Jiangping He Shuijiang Cai Huijian Feng Baomei Cai Lihui Lin Yuanbang Mai Yinqiang Fan Airu Zhu Huang Huang Junjie Shi Dingxin Li' Yuanjie Wei Yueping Li Yingying Zhao’ Yuejun Pan He Liu Xiaoneng Mo Xi He Shangtao Cao FengYu Hu Jincun Zhao Jie Wang Nanshan Zhong Xinwen Chen Xilong Deng Jiekai Chen | 2020 | Protein & Cell2020，11，9： | 7 |
| 2 | Stability and bifurcation control of a neuron system under a novel fractional-order PD controller显示文摘In this paper, we address the problem of bifurcation control for a delayed neuron system. By introducing a new fractional-order Proportional-Derivative(PD) feedback controller, this paper aims to control the stability and Hopf bifurcation through adjusting the control gain parameters. The order chosen in PD controller is different with that of the integer-order neuron system. Sufficient conditions for guaranteeing the stability and generating Hopf bifurcation are constructed for the controlled neuron system. Finally,numerical simulation results are illustrated to verify our theoretical derivations and the relationships between the onset of the Hopf bifurcation and the gain parameters are obtained. | SHI Shuo XIAO Min RONG LiNa ZHENG WeiXing TAO BinBin CHENG ZunShui XU FengYu | 2019 | Science China(Technological Sciences)2019，62，12： | 3 |
| 3 | Novel Mn-Ce bi-oxides loaded on 3D monolithic nickel foam for low-temperature NH_(3)-SCR de-NO_(x):Preparation optimization and reaction mechanism显示文摘This study explored the superior citrate method(CM)to synthesize Mn-Ce bi-oxides on 3 D monolithic Ni-foam(NF)catalysts for the selective catalytic reduction of NO by NH_(3)(NH_(3)-SCR).The 17 wt%Mn(7)Ce(3)O_(x)/NF(CM-17)catalyst shows the NO_(x)conversion of 98.7%at 175℃and 90%in the presence of 10 vol%H2 O.It is revealed that the combination of surface-active oxygen(formed by high-level oxygen vacancies)and strongly oxidized Mn4+species promots the Fast-SCR reactions,in which Mn4+species play a leading role in NH_(3)-SCR reaction,and the unsaturated Ni atoms and also Ce3+species promote electron exchange and thus improve the redox performance.The coexistence mechanisms of Fast-SCR reactions and E-R pathways are observed over Mn-CeO_(x)/NF catalyst,which may be promoted by the Br?nsted sites at low temperature.In addition,the heat resistance,stability,3 D monolithic porous structure and excellent physical properties of foam nickel provide a unique growth substrates for catalysts preparation and reaction sites for NO_(x)purification.Therefore,industrial application of Mn-Ce bioxides loaded on 3 D monolithic is proposed to be achieved through reasonable preparation methods. | Shuquan Ni Xiaolong Tang Honghong Yi Fengyu Gao Chengzhi Wang Yiran Shi Runcao Zhang Wenjuan Zhu | 2022 | Journal of Rare Earths2022，40，2： | 3 |
| 4 | Characteristics of SARS-CoV-2 Delta variant-infected individuals with intermittently positive retest viral RNA after discharge显示文摘SARS-CoV-2-infected patients will be discharged when viral ribonucleic acid(RNA)is consecutively negative at least twice over a 24-h interval.However,we have demonstrated that positive retest viral RNA,a particular clinical phenomenon initially observed in discharged SARS-CoV-2-infected patients in early 2020[1,2],is the occasional reoccurrence of Polymerase Chain Reaction(PCR)-detectable viral RNA but not reinfection[3]. | Lu Li Jingyan Tang Zhiwei Xie Qingxin Gan Guofang Tang Zhongwei Hu Huimin Zeng Jingrong Shi Jiaojiao Li Yan Li Changwen Ke Min Kang Dan Liang Huan Lu Yuwei Tong Xilong Deng Jinxin Liu Hongzhou Lu Fuxiang Wang Fengyu Hu Feng Li Nanshan Zhong Xiaoping Tang | 2022 | National Science Review2022，9，10： | 3 |
| 5 | Synthesis of polyurea from 1,6-hexanediamine with CO_2 through a two-step polymerization显示文摘Activation and transformation of CO_2 is one of the important issues in the field of green and sustainable chemistry. Herein, CO_2 as a carbonoxygen resource was converted to CO_2-polyurea with 1,6-hexanediamine through a two-step polymerization. The reaction parameters such as temperature, pressure and reaction time were examined; and several kinds of catalysts were screened in the absence and presence of NMP solvent. The formed oligomer and the final polyurea were characterized by FT-IR, VT-DRIFTS, NMR, XRD, AFM and their thermal properties were examined by TGA and DSC. It was confirmed that the final polyurea has a high thermal stability; the melting temperature is 269℃ and the decomposition temperature is above 300℃. It is a brittle polymer with a tensile strength of 18.35 MPa at break length of 1.64%. The polyurea has a stronger solvent resistance due to the ordered hydrogen bond in structure. The average molecular weight should be enhanced in the postpolymerization as the appearance, hydrogen bond intensity, crystallinity, melting point and the thermal stability changed largely compared to the oligomer. The present work provides a new kind of polyurea, it is expected to have a wide application in the field of polymer materials. | Shan Jiang Ruhui Shi Haiyang Cheng Chao Zhang Fengyu Zhao | 2017 | Green Energy & Environment2017，2，4： | 2 |
| 6 | Geochronology, geochemistry and Hf isotopes of andesites in the Sandaowanzi gold deposit(Great Xing’an Range, NE China): implications for petrogenesis, tectonic setting,and mineralization显示文摘The Sandaowanzi gold deposit is an extremely Au-rich deposit in the Northern Great Hinggan Range in recent years.Zircon U-Pb geochronology,Hf isotope analysis,and the geochemistry of andesites of the Longjiang Formation from the Sandaowanzi gold deposit were used to investigate the origin,magmatic evolution as well as mineralization and tectonic setting of the Early Cretaceous epithermal gold deposits in the northern Great Hinggan Range area.Zircon U-Pb dating reveals an emplacement age of 123.4±0.3 Ma,indicating that the andesites of the Sandaowanzi gold deposit was formed during the Early Cretaceous.The andesites are enriched in light rare earth elements relative to heavy rare earth elements and have weak negative Eu anomalies(δEu=0.76-0.90).The rocks are also enriched in large-ion lithophile elements,such as Rb,Ba,Th,U,and K,and depleted in the high-field-strength elements,such as Nb,Ta,and P.These characteristics are typical of volcanic rocks related to subduction.Igneous zircons from the andesite samples have relatively homogeneous Hf isotope ratios,176Hf/177Hf values of 0.282343-0.282502,εHf(t)values of-12.58 to-6.95,and two-stage model ages(TDM2)of 1743-1431 Ma.The characteristics of the andesites of the Longjiang Formation are consistent with derivation from partial melting of enriched mantle wedge metasomatized by subducted-slab-derived fluids.These rocks formed in an extensional environment associated with the closure of the Mongol-Okhotsk Ocean and subduction of the Paleo-Pacific Plate.Mineralization occurred towards the end of volcanism,and the magmatic activity and mineralization are products of the same geodynamic setting. | Runtao Yu Bile Li Fengyue Sun Zhihua Li Huawei Li Yufan Shi | 2021 | Acta Geochimica2021，40，2： | 2 |
| 7 | Improved impossible differential cryptanalysis of large-block Rijndael显示文摘Rijndael is a substitution-permutation network(SPN) block cipher for the AES development process. Its block and key sizes range from 128 to 256 bits in steps of 32 bits, which can be denoted by Rijndael-b-k, where b and k are the block and key sizes, respectively. Among them, Rijndael-128-128/192/256,that is, AES, has been studied by many researchers, and the security of other large-block versions of Rijndael has been exploited less frequently. However, more attention has been paid to large-block versions of block ciphers with the fast development of quantum computers. In this paper, we propose improved impossible differential attacks on 10-round Rijndael-256-256, 10-round Rijndael-224-256, and 9-round Rijndael-224-224 using precomputation tables, redundancies of key schedules, and multiple impossible differentials. For 10-round Rijndael-256-256, the data, time, and memory complexities of our attack were approximately 2^(244.4) chosen plaintexts, 2^(240.1) encryptions, and 2^(181.4) blocks, respectively. For 10-round Rijndael-224-256, the data, time, and memory complexities of our attack were approximately 2^(214.4) chosen plaintexts, 2^(241.3) encryptions, and 2^(183.4) blocks, respectively. For 9-round Rijndael-224-224, the data, time, and memory complexities of our attack are approximately 2^(214.4) chosen plaintexts, 2^(113.4) encryptions, and 2^(87.4) blocks,respectively, or 2^(206.6) chosen plaintexts, 2^(153.6) encryptions, and 2^(111.6) blocks, respectively. To the best of our knowledge, our results are currently the best on Rijndael-256-256 and Rijndael-224-224/256. | Ya LIU Yifan SHI Dawu GU Bo DAI Fengyu ZHAO Wei LI Zhiqiang LIU Zhiqiang ZENG | 2019 | Science China(Information Sciences)2019，62，3： | 1 |
| 8 | COVID-19 induces new-onset insulin resistance and lipid metabolic dysregulation via regulation of secreted metabolic factors显示文摘Abnormal glucose and lipid metabolism in COVID-19 patients were recently reported with unclear mechanism.In this study,we retrospectively investigated a cohort of COVID-19 patients without pre-existing metabolic-related diseases,and found new-onset in suli n resista nee,hyperglycemia,and decreased HDL-C in these patie nts.Mecha nistically,SARS-CoV-2 infecti on in creased the expression of RE1-silencing transcription factor(REST),which modulated the expression of secreted metabolic factors including myeloperoxidase,apelin,and myostatin at the transcriptional level,resulting in the perturbation of glucose and lipid metabolism.Furthermore,several lipids,including(±)5-HETE,(±)12-HETE,propionic acid,and isobutyric acid were identified as the potential biomarkers of COVID-19-induced metabolic dysregulation,especially in insulin resistance.Taken together,our study revealed insulin resistance as the direct cause of hyperglycemia upon COVID-19,and further illustrated the underlying mechanisms,providing potential therapeutic targets for COVID-19-induced metabolic complications. | Xi He Chenshu Liu Jiangyun Peng Zilun Li Fang Li Jian Wang Ao Hu Meixiu Peng Kan Huang Dongxiao Fan Na Li Fuchun Zhang Weiping Cai Xinghua Tan Zhongwei Hu Xilong Deng Yueping Li Xiaoneng Mo Linghua Li Yaling Shi Li Yang Yuanyuan Zhu Yanrong Wu Huichao Liang Baolin Liao Wenxin Hong Ruiying He Jiaojiao Li Pengle Guo Youguang Zhuo Lingzhai Zhao Fengyu Hu Wenxue Li Wei Zhu Zefeng Zhang Zeling Guo Wei Zhang Xiqiang Hong Wei kang Cai Lei Gu Ziming Du Yang Zhang Jin Xu Tao Zuo Kai Deng Li Yan Xinwen Chen Sifan Chen Chunliang Lei | 2022 | Signal Transduction and Targeted Therapy2022，7，1： | 0 |

| 10 | CdS nanoparticles decorated hexagonal Fe_(2)O_(3) nanosheets with a Z-scheme photogenerated electron transfer path for improved visible-light photocatalytic hydrogen production显示文摘Photocatalytic water splitting for hydrogen production(H_(2))is one of the main potential applications of photocatalytic technology,which can use solar energy as the energy required for chemical reactions to alleviate the energy crisis.In this work,zero-dimensional/two-dimensional(0D/2D)contact surface CdS/α-Fe_(2)O_(3)(CF)heterojunction photocatalyst was synthesized via a simple solvothermal method.Photocatalytic hydrogen production experiments revealed that the CF-15 sample shows the optimal photocatalytic H_(2)rate(1806μmol·h^(-1)·g^(-1))and apparent quantum efficiency(AQE=13.7%atλ=420 nm).The enhancement of photocatalytic performance is mainly attributed to the contact of 0D/2D interface and the synergistic effect of Z-scheme electron transfer mechanism.This work provides an effective way for modified composite semiconductor photocatalyst by constructing special interface heterojunction to achieve highly efficiently catalysis. | Feng Guo Haoran Sun Yuxing Shi Fengyu Zhou Weilong Shi | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 0 |

| 12 | Effects of Blending Long-Chain Alcohols with Jet Fuel on the Macroscopic Spray Characteristics显示文摘Long-chain alcohols were considered to be promising alternative fuels and fuel additives. This study was aimed at figuring out the influences of blending long-chain alcohols with jet fuel on the macroscopic spray characteristic. n-Butanol and n-pentanol were chosen as tested alternative fuels. A common-rail injection system was used to create high-pressure injection conditions. The Schlieren imaging system was used to capture spray processes. Results showed that with the addition of long-chain alcohols, the spray tip penetration and the peak spray tip velocity increased, whereas the spray cone angle and the spray area decreased. Comparisons between those macroscopic spray characteristics of AKB blends and AKP blends were also conducted. Compared to AKB blends, AKP blends showed similar spray tip penetration, larger peak tip velocity, smaller spray cone angle, and smaller spray area. | Li Fengyu Liu Yanju Huang Qifu Fu Wei Shi Weidong Lin Qizhao | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，4： | 0 |
| 13 | Retrospective Analysis of the Duration of Hospitalization of Imported Patients Infected with SARS-CoV-2 in Guangzhou, 2021显示文摘The pandemic of coronavirus disease 2019 is“not over,”in fact,the“dynamic clearing”policy for SARS-CoV-2 control and prevention in China has been firmly enforced.This study aimed to analyze the clinical symptoms and dynamic viral RNA changes in 2021 at Guangzhou Eighth People’s Hospital.This study showed that 31.4%of the patients(695/2212)tested negative for viral RNA from admission to the final release from quarantine.Of all negative cases,86.5%(601/695)remained in the hospital for no more than 5 days and were asymptomatic or mild.Among the remaining 402 patients who stayed for no more than 5 days,76.4%(307/402)were viral RNA retest positive during the isolation stage.However,96.4%of the peak viral RNA(296/307)was over Ct=33 cycles during the isolation stage. | Zhiwei Xie Guofang Tang Lu Li Jingrong Shi Qingxin Gan Xiaowen Zheng Jingyan Tang Huimin Zeng Chuyu Zhang Sisi Cheni Jianping Cui Zishi Lin Lihua Lin Youxia Li Jinxin Liu Feng Li Fengyu Hui Xiaoping Tang Xilong Deng | 2023 | Infectious Diseases & Immunity2023，3，1： | 0 |
| 14 | Cyclic oligourea synthesized from CO_(2):Purification,characterization and properties显示文摘Carbon dioxide(CO_(2)) as a sustainable resource instead of toxic reagents has attracted considerable attention in synthesis of chemicals and polymeric materials.Herein,a kind of cyclic oligourea was synthesized via polycondensation of CO_(2) with 4,7,10-trioxa-1,13-tridecanediamine(TTD)followed by effective separation and purification processes.We developed an efficient separation strategy in which the linear oligourea molecules were selectively transformed to macromolecular polyurea molecules by a reaction of the–NH_(2) end group with 4,4’-diphenylmethane diisocyanate(MDI),followed by separation from cyclic oligourea using selected solvents.The structure and physicochemical properties were confirmed by MALDI-TOF mass spectra,NMR,Cryo-EM,thermal analysis and solubility measurement.The well-defined cyclic oligourea was produced with a high purity(99.4%)and the average-number molecular weight(Mn)of 1040 Da.It is semi-crystalline in structure with a melting point of 106℃and glass transition point of-10℃.The cyclic oligourea presented characteristically difference to its linear analogue.This work provides a new member to cyclic polymer family. | Ruhui Shi Haiyang Cheng Hongxiang Li Peixuan Wu Chao Zhang Masahiko Arai Fengyu Zhao | 2022 | Green Energy & Environment2022，7，3： | 0 |
