| 1 | Low frequency wide bandwidth MEMS energy harvester based on spiral-shaped PVDF cantilever显示文摘In this paper,a piezoelectric energy harvester based on spiral-shaped polyvinylidene fluoride(PVDF)cantilever is designed and fabricated for harvesting low frequency vibration energy in the environment.In this design,the spiral-shaped PVDF cantilever is major for lowering the resonant frequency by increasing the length of the cantilever;Copper and silicon proof masses on both sides are working on further decreasing the resonant frequency and widen its bandwidth.Due to the high flexibility of the PVDF cantilever,this device is extremely sensitive to vibration and can harvest weak vibration energy.Both simulation and experimental results have approved that this device can operate at very low frequency which is about 20 Hz and can effectively harvest energy from 15–50 Hz.The peak of the output voltage can reach 1.8 V with the acceleration of 0.2 g.This is a promising harvester for powering the wireless sensors in the future. | LIU Wen HAN MengDi MENG Bo SUN XuMing HUANG XianLiang ZHANG HaiXia | 2014 | Science China(Technological Sciences)2014，57，6： | 13 |

| 3 | Highly efficient and selective CO2 electro-reduction with atomic Fe-C-N hybrid coordination on porous carbon nematosphere显示文摘Carbon dioxide reduction(CO2RR)has become a promising way to address the energy and environmental crisis,of which the fundamental development of the optimal electrocatalysts is the crucial part.Herein,we develop Fe and N doping porous carb on n ematosphere(FeNPCN)as an excellent CO2RR electrocatalyst in aqueous electrolyte.Featuring with the high conductivity,pore structure and abundant Fe and N doping,FeNPCN exhibits high catalytic activity with a high faradaic selectivity of CO(94%)and long-term durability.Moreover,the ratio of CO and H2 can be changed by the applied potential for the different syngas related industry.Density functional theory(DFT)calculation results also reveal that the excellent catalytic activity is likely attributed to C and N hybrid coordination with atomic Fe. | Haixia Zhong Fanlu Meng Qi Zhang Kaihua Liu Xinbo Zhang | 2019 | Nano Research2019，12，9： | 8 |
| 4 | Risk of gestational diabetes recurrence and the development of type 2 diabetes among women with a history of gestational diabetes and risk factors: a study among 18 clinical centers in China显示文摘Background:Gestational diabetes mellitus(GDM)brings health issues for both mothers and offspring,and GDM prevention is as important as GDM management.It was shown that a history of GDM was significantly associated with a higher maternal risk for GDM recurrence.The incidence of GDM recurrence was unclear because of the incidence of second-child was low before 2016 in China.We aim to investigate the prevalence of GDM recurrence and its associated high-risk factors which may be useful for the prediction of GDM recurrence in China.Methods:A retrospective study was conducted which enrolled participants who underwent regular prenatal examination and delivered twice in the same hospital of 18 research centers.All participants were enrolled from January 2018 to October 2018,where they delivered the second baby during this period.A total of 6204 women were enrolled in this study,and 1002 women with a history of GDM were analyzed further.All participants enrolled in the study had an oral glucose tolerance test(OGTT)result at 24 to 28 weeks and were diagnosed as GDM in the first pregnancy according to the OGTT value(when any one of the following values is met or exceeded to the 75-g OGTT:0 h[fasting],≥5.10 mmol/L;1 h,≥10.00 mmol/L;and 2 h,≥8.50 mmol/L).The prevalence of GDM recurrence and development of type 2 diabetes mellitus were calculated,and its related risk factors were analyzed.Results:In 6204 participants,there are 1002 women(1002/6204,16.15%)with a history of GDM and 5202 women(5202/6204,83.85%)without a history of GDM.There are significant differences in age(32.43±4.03 years vs.33.00±3.34 years vs.32.19±3.37 years,P<0.001),pregnancy interval(4.06±1.44 years vs.3.52±1.43 years vs.3.38±1.35 years,P=0.004),prepregnancy body mass index(BMI)(27.40±4.62 kg/m^(2)vs.23.50±3.52 kg/m^(2)vs.22.55±3.47 kg/m^(2),P<0.001),history of delivered macrosomia(22.7%vs.11.0%vs.6.2%,P<0.001)among the development of diabetes mellitus(DM),recurrence of GDM,and normal women.Moreover,it seems so important in the degree of abnormal glucose metabolism in the first pregnancy to the recurrence of GDM and the development of DM.There are significant differences in OGTT levels of the first pregnancy such as area under the curve of OGTT value(18.31±1.90 mmol/L vs.16.27±1.93 mmol/L vs.15.55±1.92 mmol/L,P<0.001),OGTT fasting value(5.43±0.48 mmol/L vs.5.16±0.49 mmol/L vs.5.02±0.47 mmol/L,P<0.001),OGTT 1-hour value(10.93±1.34 mmol/L vs.9.69±1.53 mmol/L vs.9.15±1.58 mmol/L,P<0.001),OGTT 2-hour value(9.30±1.66 mmol/L vs.8.01±1.32 mmol/L vs.7.79±1.38 mmol/L,P<0.001),incidence of impaired fasting glucose(IFG)(fasting plasma glucose≥5.6 mmol/L)(31.3%vs.14.6%vs.8.8%,P<0.001),and incidence of two or more abnormal OGTT values(68.8%vs.39.7%vs.23.9%,P<0.001)among the three groups.Using multivariate analysis,the factors,such as age(1.07[1.02-1.12],P=0.006),prepregnancy BMI(1.07[1.02,1.12],P=0.003),and area under the curve of OGTT in the first pregnancy(1.14[1.02,1.26],P=0.02),have an effect on maternal GDM recurrence;the factors,such as age(1.28[1.01-1.61],P=0.04),pre-pregnancy BMI(1.26[1.04,1.53],P=0.02),and area under the curve of OGTT in the first pregnancy(1.65[1.04,2.62],P=0.03),have an effect on maternal DM developed further.Conclusions:The history of GDM was significantly associated with a higher maternal risk for GDM recurrence during follow-up after the first pregnancy.The associated risk factors for GDM recurrence or development of DM include age,high pre-pregnancy BMI,history of delivered macrosomia,the OGTT level in the first pregnancy,such as the high area under the curve of OGTT,IFG,and two or more abnormal OGTT values.To prevent GDM recurrence,women with a history of GDM should do the preconception counseling before preparing next pregnancy. | Yumei Wei Juan Juan Rina Su Geng Song Xu Chen Ruiqin Shan Ying Li Shihong Cui Shangrong Fan Ling Feng Zishan You Haixia Meng Yan Cai Cuilin Zhang Huixia Yang | 2022 | Chinese Medical Journal2022，，6： | 7 |
| 5 | Arsenic trioxide alleviates acute graft-versus-host disease by modulating macrophage polarization显示文摘This study aimed to explore macrophage polarization in acute graft-versus-host disease after hematopoietic stem cell transplantation, and investigated if arsenic trioxide(ATO) could correct this imbalance. In the colon of GVHD mice, we found that the number of F4/80+iNOS+ cells as well as the expression intensity of TNF-α and IL-1β was greater in the GVHD group than in the BM group, whereas the number of F4/80+CD206+ cells and the expression intensity of IL-10 and TGF-β was greater in the BM group than in the GVHD group. We investigated the effect of ATO on GVHD mice, and found that ATO treatment clearly improved the survival of the mice and reduced the severity of GVHD. In addition, ATO reduced the number of F4/80+iNOS+ cells, and increased the number of F4/80+CD206+ cells in the colon of GVHD mice. Furthermore, ATO sharply decreased CD86 and CD80 expression, and increased CD163 and CD206 expression in macrophages induced from aGVHD patients. Therefore,ATO can modulate the M1 and M2 phenotype in GVHD mice or in macrophages from aGVHD patients. Our data suggest that macrophage polarization is involved in the pathogenesis of aGVHD, and ATO treatment modulates macrophage polarization toward an M2 phenotype. | Xiao Liu Yan Su Xueyan Sun Haixia Fu Qiusha Huang Qi Chen Xiaodong Mo Meng Lv Yuan Kong Lanping Xu Xiaojun Huang Xiaohui Zhang | 2020 | Science China(Life Sciences)2020，63，11： | 6 |
| 6 | Gut microbiome alterations and its link to corticosteroid resistance in immune thrombocytopenia显示文摘Quantitative metagenomic studies have linked the gut microbiota to autoimmune disorders.Here,we performed deep shotgun metagenomic sequencing of fecal samples from 99 immune thrombocytopenia(ITP)patients and 52 healthy controls.Dysbiosis in the gut microbiome of ITP was detected phylogenetically and functionally,and classifier based on species markers distinguished individuals with ITP from healthy controls.In particular,the abundance of Ruminococcus gnavus,Bifidobacterium longum and Akkermansia muciniphila was markedly increased in treatment-na?ve ITP patients,and the alterations of microbial species were correlated with clinical indices.Functionally,the secondary bile acid biosynthesis and flagellar assembly were depleted in the gut microbiota of ITP,which may contribute to the onset of ITP by affecting the immune system.Furthermore,we found that corticosteroid treatment affected the gut microbiome of ITP.Compared with corticosteroid-sensitive ITP patients,we identified that the corticosteroid-resistant ITP patients displayed a distinct gut microbiome,which was different from that of the treatment-na?ve ITP patients.Together,we provided support for the critical role of gut microbiota in the development of ITP and established a foundation for further research characterizing gut microbiota in relation to corticosteroid resistance of ITP. | Yanan Wang Fengqi Liu Gaochao Zhang Yan Su Xueyan Sun Qi Chen Chencong Wang Haixia Fu Yun He Xiaolu Zhu Xiao Liu Meng Lv Xiangyu Zhao Xiaosu Zhao Yueying Li Qianfei Wang Xiaojun Huang Xiaohui Zhang | 2021 | Science China(Life Sciences)2021，64，5： | 6 |

| 10 | A cubic triboelectric generator as a self-powered orientation sensor显示文摘Recently, triboelectric generator(TEG) has attracted a lot of attention due to its high output voltage and low-cost fabrication process. Here, a novel cubic TEG box is designed, which has separated electrodes on different surfaces. Thanks to the specially designed structure, it can scavenge vibration energy from all directions. Firstly the device is investigated through finite element method(FEM) simulation. Then the device is evaluated by experiments. The measuremental results show that this device can generate an amount of 25 n C charge during once shake by charging a 10 n F capacitor. Besides, an output voltage about 100 V is obtained, which is able to directly light up several light-emitting diodes(LEDs) simultaneously. At last, the device is utilized as a self-powered orientation sensor, which shows explicit directivity. This work extends the applications of TEG for ambient vibration energy harvesting techniques and the self-powered orientation sensor. | QIU GuoLin LIU Wen HAN MengDi CHENG XiaoLiang MENG Bo SMITHA Ankanahalli Shankaregowda ZHAO JiangMing ZHANG HaiXia | 2015 | Science China(Technological Sciences)2015，58，5： | 2 |

| 13 | Assessing the mechanism of citywide test-trace-isolate Zero-COVID policy and exit strategy of COVID-19 pandemic显示文摘Background:Countries that aimed for eliminating the cases of COVID-19 with test-trace-isolate policy are found to have lower infections,deaths,and better economic performance,compared with those that opted for other mitigation strategies.However,the continuous evolution of new strains has raised the question of whether COVID-19 eradication is still possible given the limited public health response capacity and fatigue of the epidemic.We aim to investigate the mechanism of the Zero-COVID policy on outbreak containment,and to explore the possibility of eradication of Omicron transmission using the citywide test-trace-isolate(CTTI)strategy.Methods:We develop a compartmental model incorporating the CTTI Zero-COVID policy to understand how it contributes to the SARS-CoV-2 elimination.We employ our model to mimic the Delta outbreak in Fujian Province,China,from September 10 to October 9,2021,and the Omicron outbreak in Jilin Province,China for the period from March 1 to April 1,2022.Projections and sensitivity analyses were conducted using dynamical system and Latin Hypercube Sampling/Partial Rank Correlation Coefcient(PRCC).Results:Calibration results of the model estimate the Fujian Delta outbreak can end in 30(95%confdence interval CI:28–33)days,after 10(95%CI:9–11)rounds of citywide testing.The emerging Jilin Omicron outbreak may achieve zero COVID cases in 50(95%CI:41–57)days if supported with sufcient public health resources and population compliance,which shows the efectiveness of the CTTI Zero-COVID policy.Conclusions:The CTTI policy shows the capacity for the eradication of the Delta outbreaks and also the Omicron outbreaks.Nonetheless,the implementation of radical CTTI is challenging,which requires routine monitoring for early detection,adequate testing capacity,efcient contact tracing,and high isolation compliance,which constrain its benefts in regions with limited resources.Moreover,these challenges become even more acute in the face of more contagious variants with a high proportion of asymptomatic cases.Hence,in regions where CTTI is not possible,personal protection,public health control measures,and vaccination are indispensable for mitigating and exiting the COVID-19 pandemic. | Pei Yuan Yi Tan Liu Yang Elena Arufo Nicholas H.Ogden Guojing Yang Haixia Lu Zhigui Lin Weichuan Lin Wenjun Ma Meng Fan Kaifa Wang Jianhe Shen Tianmu Chen Huaiping Zhu | 2022 | Infectious Diseases of Poverty2022，11，5： | 0 |

| 18 | Observation-based sources evolution of non-methane hydrocarbons (NMHCs) in a megacity of China显示文摘Both concentrations and emissions of many air pollutants have been decreasing due to implement of control measures in China,in contrast to the fact that an increase in emissions of non-methane hydrocarbons(NMHCs)has been reported.This study employed seven years continuous NMHCsmeasurements and the related activities data of Shanghai,a megacity in China,to explore evolution of emissions and effectiveness of air pollution control measures.The mixing ratio of NMHCs showed no statistical interannual changes,of which their compositions exhibited marked changes.This resulted in a decreasing trend of ozone formation potential by 3.8%/year(p<0.05,the same below),which should be beneficial to ozone pollution mitigation as its production in Shanghai is in the NMHCs-limited regime.Observed alkanes,aromatics and acetylene changed by+3.7%/year,-5.9%/year and-7.4%/year,respectively,and alkenes showed no apparent trend.NMHCs sources were apportioned by a positive matrix factorization model.Accordingly,vehicular emissions(-5.9%/year)and petrochemical industry emissions(-7.1%/year)decreased significantly,but the decrease slowed down;significant reduction in solvent usage(-9.0%/year)appeared after 2010;however,emissions of natural gas(+12.6%/year)and fuel evaporation(with an increasing fraction)became more important.The inconsistency between observations and inventories was found in interannual trend and speciation as well as source contributions,emphasizing the need for further validation in NMHCs emission inventory.Our study confirms the effectiveness of measures targeting mobile and centralized emissions from industrial sources and reveals a need focusing on fugitive emissions,which provided new insights into future air policies in polluted region. | Yarong Peng Hongli Wang Qian Wang Shengao Jing Jingyu An Yaqin Gao Cheng Huang Rusha Yan Haixia Dai Tiantao Cheng Qiang Zhang Meng Li Jianlin Hu Zhihao Shi Li Li Shengrong Lou Shikang Tao Qinyao Hu Jun Lu Changhong Chen | 2023 | Journal of Environmental Sciences2023，，2： | 0 |
