| 1 | Wearable skin-like optoelectronic systems with suppression of motion artifacts for cuff-less continuous blood pressure monitor显示文摘According to the statistics of the World Health Organization,an estimated 17.9 million people die from cardiovascular diseases each year,representing 31%of all global deaths.Continuous non-invasive arterial pressure(CNAP)is essential for the management of cardiovascular diseases.However,it is difficult to achieve long-term CNAP monitoring with the daily use of current devices due to irritation of the skin as well as the lack of motion artifacts suppression.Here,we report a high-performance skin-like optoelectronic system integrated with ultra-thin flexible circuits to monitor CNAP.We introduce a theoretical model via the virtual work principle for predicting the precise blood pressure and suppressing motion artifacts,and propose optical difference in the frequency domain for stable optical measurements in terms of skin-like devices.We compare the results with the blood pressure acquired by invasive(intra-arterial)blood pressure monitoring for>1500 min in total on 44 subjects in an intensive care unit.The maximum absolute errors of diastolic and systolic blood pressure were±7/±10 mm Hg,respectively,in immobilized,and±10/±14 mm Hg,respectively,in walking scenarios.These strategies provide advanced blood pressure monitoring techniques,which would directly address an unmet clinical need or daily use for a highly vulnerable population. | Haicheng Li Yinji Ma Ziwei Liang Zhouheng Wang Yu Cao Yuan Xu Hua Zhou Bingwei Lu Ying Chen Zhiyuan Han Shisheng Cai Xue Feng | 2020 | National Science Review2020，7，5： | 7 |

| 4 | Studying the urban hierarchical pattern and spatial structure of China using a synthesized gravity model显示文摘The Gravity Model(GM), one of the most classic models adopted by the domain of social sciences from physics, has been widely used to study the interactions between social identities. Previous research that has used the Gravity Model to study the interactions among cities have mostly used a single variable, such as population or GDP, to represent a city, which does not provide a comprehensive depiction of a city's influence. This paper develops a Synthesized Gravity Model(SGM) based on the traditional Gravity Model to study the evolution of the hierarchy of the Chinese urban system since the mid-1990 s. Under this model, socioeconomic variables are synthesized and are represented by the Influential Factor, while the Function Distance is derived from a Network Analysis that is based on multiple transportation methods. As an improvement on the GM, the SGM is used to accurately establish and represent the nodal structure of China's urban system, the evolution of its hierarchical structure,and the relationships that exist between the nodal structure and socioeconomic factors. The results based on the SGM indicate that China's national urban system is characterized by the emergence of urban clusters with stronger inter-city interactions since the 1990 s. However, the development among cities within certain urban clusters is not even, although the general pattern indicates a lessening inequality amongst cities. Spatially, while most cities at the top of the hierarchy are located in Eastern China, cities in the center and the west of the country are also gaining higher positions in the hierarchy over time. This paper is dedicated to improving the traditional GM in the applications of urban studies, while the system of Chinese cities is used to validate the SGM. | Ruibo HAN Huhua CAO Ziwei LIU | 2018 | Science China Earth Sciences2018，61，12： | 5 |
| 5 | A fully automated centrifugal microfluidic system for sample-to-answer viral nucleic acid testing显示文摘The outbreak of virus-induced infectious diseases poses a global public-health challenge.Nucleic acid amplification testing(NAAT)enables early detection of pandemic viruses and plays a vital role in preventing onward transmission.However,the requirement of skilled operators,expensive instrumentation,and biosafety laboratories has hindered the use of NAAT for screening and diagnosis of suspected patients.Here we report development of a fully automated centrifugal microfluidic system with sample-in-answer-out capability for sensitive,specific,and rapid viral nucleic acid testing.The release of nucleic acids and the subsequent reverse transcription loop-mediated isothermal amplification(RT-LAMP)were integrated into the reaction units of a microfluidic disc.The whole processing steps such as injection of reagents,fluid actuation by rotation,heating and temperature control,and detection of fluorescence signals were carried out automatically by a customized instrument.We validate the centrifugal microfluidic system using oropharyngeal swab samples spiked with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)armored RNA particles.The estimated limit of detection for armored RNA particles is 2 copies per reaction,the throughput is 21 reactions per disc,and the assay sample-to-answer time is approximately 70 min.This enclosed and automated microfluidic system efficiently avoids viral contamination of aerosol,and can be readily adapted for virus detection outside the diagnostic laboratory. | Fei Tian Chao Liu Jinqi Deng Ziwei Han Lu Zhang Qinghua Chen Jiashu Sun | 2020 | Science China Chemistry2020，63，10： | 4 |
| 6 | Surface modification with ionic liquid for efficient CsPbI2Br perovskite solar cells显示文摘The presence of numerous trap states on the perovskite surface severely affects the performance of inorganic CsPbI_(2)Br perovskite solar cells.Surface modification has been proven to be an effective strategy to passivate the surface trap states of CsPbI_(2)Br perovskite.However,most modifiers behave high volatility and insulation,not enough to further develop the CsPbI_(2)Br solar cells.Herein,an ionic liquid of 1-viny-3-propionate ethyl imidazolium chloride([PEVIM]Cl)is applied to modify the CsPbI_(2)Br film surface,yielding a compact film with enhanced crystallinity.The surface trap states of CsPbI_(2)Br film are effectively passivated via the interaction between carbonyl group of[PEVIM]Cl and uncoordinated metal cations of CsPbI_(2)Br perovskite,leading to charge recombination suppression and charge transport enhancement.Consequently,the power conversion efficiency(PCE)of[PEVIM]Cl modified CsPbI_(2)Br device is obviously enhanced from 12.49% to 14.19% with an improved open-circuit voltage of 1.160 V.Moreover,the non-encapsulated device presents excellent thermal stability,still maintaining 91%PCE when heated at 85℃ in nitrogen atmosphere for 360 h.Meanwhile,the non-encapsulated device degrades only 11% PCE after stored at 50% relative humidity for 960 h.This simple and efficient approach provides a promising direction to fabricate high-efficiency and stable inorganic perovskite devices. | Xingyu Pu Jian Han Shuangjie Wang Hui Zhou Qi Cao Jiabao Yang Ziwei He Xuanhua Li | 2021 | Journal of Materiomics2021，7，5： | 3 |
| 7 | Gravity variation in the Tibet area before the Nepal Ms8.1 earthquake显示文摘This research utilized two periods of gravity monitoring results from 2010 to 2013 from the Continental Tectonics Environmental Monitoring Network of China,analyzed the correlation between gravity variation in the Tibet area and the Nepal Ms8.1 earthquake,and investigated the gravity variation mechanism in combination with the crust vertical movement and horizontal strain field observed by Global Positioning System(GPS).The research results indicated that(1) the gravity variation exhibited apparent characteristics of a positive anomaly and high gradient zone in the Himalayan frontier.This observation is consistent with the existing recognition of the gravity anomaly and occurrence regularity of a strong earthquake;(2) the gravity variation exhibited apparent consistence with the spacious distribution of the vertical movement and the horizontal deformation field in that area.The crustal vertical movement was not the direct cause leading to the gravity variation.It is assumed that the crust stressestrain accumulation in the Qinghaie Tibetan Plateau and its adjacent areas is the important factor that resulted in the variation of gravity. | Hongtao Hao Lelin Xing Ziwei Liu YUfei Han Hui Li | 2016 | Geodesy and Geodynamics2016，7，6： | 3 |
| 8 | MEMS inductor fabrication and emerging applications in power electronics and neurotechnologies显示文摘MEMS inductors are used in a wide range of applications in micro-and nanotechnology,including RF MEMS,sensors,power electronics,and Bio-MEMS.Fabrication technologies set the boundary conditions for inductor design and their electrical and mechanical performance.This review provides a comprehensive overview of state-of-the-art MEMS technologies for inductor fabrication,presents recent advances in 3D additive fabrication technologies,and discusses the challenges and opportunities of MEMS inductors for two emerging applications,namely,integrated power electronics and neurotechnologies.Among the four top-down MEMS fabrication approaches,3D surface micromachining and through-substrate-via(TSV)fabrication technology have been intensively studied to fabricate 3D inductors such as solenoid and toroid in-substrate TSV inductors.While 3D inductors are preferred for their high-quality factor,high power density,and low parasitic capacitance,in-substrate TSV inductors offer an additional unique advantage for 3D system integration and efficient thermal dissipation.These features make in-substrate TSV inductors promising to achieve the ultimate goal of monolithically integrated power converters.From another perspective,3D bottom-up additive techniques such as ice lithography have great potential for fabricating inductors with geometries and specifications that are very challenging to achieve with established MEMS technologies.Finally,we discuss inspiring and emerging research opportunities for MEMS inductors. | Hoa Thanh Le Rubaiyet I.Haque Ziwei Ouyang Seung Woo Lee Shelley I.Fried Ding Zhao Min Qiu Anpan Han | 2021 | Microsystems & Nanoengineering2021，7，4： | 2 |
| 9 | Pattern recognition in multi-synaptic photonic spiking neural networks based on a DFB-SA chip显示文摘Spiking neural networks(SNNs)utilize brain-like spatiotemporal spike encoding for simulating brain functions.Photonic SNN offers an ultrahigh speed and power efficiency platform for implementing high-performance neuromorphic computing.Here,we proposed a multi-synaptic photonic SNN,combining the modified remote supervised learning with delayweight co-training to achieve pattern classification.The impact of multi-synaptic connections and the robustness of the network were investigated through numerical simulations.In addition,the collaborative computing of algorithm and hardware was demonstrated based on a fabricated integrated distributed feedback laser with a saturable absorber(DFB-SA),where 10 different noisy digital patterns were successfully classified.A functional photonic SNN that far exceeds the scale limit of hardware integration was achieved based on time-division multiplexing,demonstrating the capability of hardware-algorithm co-computation. | Yanan Han Shuiying Xiang Ziwei Song Shuang Gao Xingxing Guo Yahui Zhang Yuechun Shi Xiangfei Chen Yue Hao | 2023 | Opto-Electronic Science2023，2，9： | 1 |
| 10 | Flexible inorganic bioelectronics显示文摘Flexible inorganic bioelectronics represent a newly emerging and rapid developing research area.With its great power in enhancing the acquisition,management and utilization of health information,it is expected that these flexible and stretchable devices could underlie the new solutions to human health problems.Recent advances in this area including materials,devices,integrated systems and their biomedical applications indicate that through conformal and seamless contact with human body,the measurement becomes continuous and convenient with yields of higher quality data.This review covers recent progresses in flexible inorganic bio-electronics for human physiological parameters’monitoring in a wearable and continuous way.Strategies including materials,structures and device design are introduced with highlights toward the ability to solve remaining challenges in the measurement process.Advances in measuring bioelectrical signals,i.e.,the electrophysiological signals(including EEG,ECoG,ECG,and EMG),biophysical signals(including body temperature,strain,pressure,and acoustic signals)and biochemical signals(including sweat,glucose,and interstitial fluid)have been summarized.In the end,given the application property of this topic,the future research directions are outlooked. | Ying Chen Yingchao Zhang Ziwei Liang Yu Cao Zhiyuan Han Xue Feng | 2020 | npj Flexible Electronics2020，4，1： | 1 |
| 11 | Dihydroartemisinin induces ER stress-dependent apoptosis of Echinococcus protoscoleces in vitro显示文摘In this study,we investigated the effect of dihydroartemisinin on Echinococcus protoscoleces and explored the role of endoplasmic reticulum stress in this process.Echinococcus protoscoleces were collected and cultured in RPMI 1640 medium.Changes in the expressions of glucose-regulated protein 78(GRP-78),caspase-12,and C/EBP homologous protein(CHOP)were assessed through confocal immunofluorescence and western blot analysis.Cell viability and morphological changes were observed under a light microscope.The ultrastructure of protoscoleces was observed by scanning electron microscopy and transmission electron microscopy.Caspase-3 activity was detected using an enzyme assay kit.After dihydroartemisinin treatment,the protoscoleces showed loss of viability,and morphological changes including soma contraction,blebs formation,hooks loss,microtrichia destruction,and development of lipid droplets was observed.The levels of caspase-12 and CHOP were increased within 2 days of dihydroartemisinin treatment.However,the levels of GRP-78,caspase-12,and CHOP were decreased in 4 days.Furthermore,caspase-3 activity was increased after treatment with different concentrations of dihydroartemisinin.Dihydroartemisinin can induce apoptosis in protoscoleces via the ER stress-caspase-3 apoptotic pathway in vitro.These results indicate that dihydroartemisinin is a potentially valuable therapeutic agent against echinococcosis. | Rongji Ma Wenjuan Qin Yuanmao Xie Ziwei Han Shuojie Li Yufeng Jiang Hailong Lv | 2020 | Acta Biochimica et Biophysica Sinica2020，52，10： | 1 |
| 12 | Exosomes in cancer immunoediting and immunotherapy显示文摘As an important means of communication among cells,exosomes are being studied more and more widely,especially in the context of cancer immunotherapy.In the phase of tumor immunoediting,exosomes derived from tumor cells and different immune cells have complex and changeable physiological functions,because they carry different proteins and nucleic acid from the source cells.Based on the role of exosomes in the communication between different cells,cancer treatment methods are also under continuous research.This review briefly introduces the molecular composition of exosomes,which is closely related to their secretion mechanism.Subsequently,the role of exosomes encapsulating different information molecules is summarized.The role of exosomes in the three phases of tumor immunoediting is introduced in detail,and the relevant literature of exosomes in the tumor immunemicroenvironment is summarized by using a novel framework for extracting relevant documents.Finally,it summarizes the various exosome-based immunotherapies currently proposed,as well as the challenges and future prospects of exosomes in tumor immunotherapy. | Yarong Zhao Luotong Liu Rongze Sun Guilin Cui Shuyu Guo Songren Han Ziwei Li Tian Bai Lesheng Teng | 2022 | Asian Journal of Pharmaceutical Sciences2022，17，2： | 1 |

| 14 | Tailoring the mercaptan ligands for high performance inverted perovskite solar cells with efficiency exceeding 21%显示文摘Interface passivation engineering has been recognized as an effective way to simultaneously contribute to the optoelectronic characteristic and stability of perovskite solar cells(PSCs). Herein, a p-conjugated dual-ligand 1,4-phenylmercaptan(PHMT) is explored to rationally tailor the surface of perovskite film.The experimental and theoretical results show that the PHMT presents planar structure and obvious electron delocalization characteristics, which allow it to anchor on the surface of perovskite with a certain orientation, thereby promoting the transport of interface charge. Moreover, the two sulfhydryl groups in PHMT reduce the trap density of the perovskite film by passivating under-coordinated lead ions.Consequently, the PHMT-modified inverted device based on MAPbI_(3)(MA: methylammonium) achieves enhanced efficiency from 18.11%(control) to 21.11%, along with the ambient stability up to 3500 h.After being placed at 85 °C for 500 h or illuminated for 600 h, the modified device remains over 89%or 86% of initial efficiency. This discovery opens a new window for the choice of passivators to improve the performance of PSCs. | Shuangjie Wang Ziwei He Jiabao Yang Tongtong Li Xingyu Pu Jian Han Qi Cao Bingyu Gao Xuanhua Li | 2021 | Journal of Energy Chemistry2021，30，9： | 1 |
| 15 | Photonic integrated neuro-synaptic core for convolutional spiking neural network显示文摘Neuromorphic photonic computing has emerged as a competitive computing paradigm to overcome the bottlenecks of the von-Neumann architecture.Linear weighting and nonlinear spike activation are two fundamental functions of a photonic spiking neural network(PSNN).However,they are separately implemented with different photonic materials and devices,hindering the large-scale integration of PSNN.Here,we propose,fabricate and experimentally demonstrate a photonic neuro-synaptic chip enabling the simultaneous implementation of linear weighting and nonlinear spike activation based on a distributed feedback(DFB)laser with a saturable absorber(DFB-SA).A prototypical system is experimentally constructed to demonstrate the parallel weighted function and nonlinear spike activation.Furthermore,a fourchannel DFB-SA laser array is fabricated for realizing matrix convolution of a spiking convolutional neural network,achieving a recognition accuracy of 87%for the MNIST dataset.The fabricated neuro-synaptic chip offers a fundamental building block to construct the large-scale integrated PSNN chip. | Shuiying Xiang Yuechun Shi Yahui Zhang Xingxing Guo Ling Zheng Yanan Han Yuna Zhang Ziwei Song Dianzhuang Zheng Tao Zhang Hailing Wang Xiaojun Zhu Xiangfei Chen Min Qiu Yichen Shen Wanhua Zheng Yue Hao | 2023 | Opto-Electronic Advances2023，6，11： | 1 |
| 16 | Differential bone metabolism and protein expression in mice fed a high-fat diet versus Daurian ground squirrels following natural pre-hibernation fattening显示文摘This study compared the effects on bone metabolism and morphology of pathological obesity induced by excessive fat intake in a non-hibernator(mice)versus healthy obesity due to pre-hibernation fattening in a hibernator(ground squirrels).Kunming mice were fed a high-fat diet to provide a model of pathological obesity(OB group).Daurian ground squirrels fattened naturally in their pre-hibernation season(PRE group)were used as a healthy obesity model.Micro-computed tomography(micro-CT)and three-point bending tests were used to determine the microstructure and mechanical properties of bone.Western blots were used to analyze protein expression levels related to bone metabolism(Runt-related transcription factor 2(RunX2),osteocalcin(OCN),alkaline phosphatase(ALP),osteoprotegerin(OPG),receptor activator of nuclear factor-κB ligand(RANKL),cathepsin K,matrix metallopeptidase 9(MMP9),patched protein homolog 1(Ptch1),phosphorylatedβ-catenin(P-β-catenin),and glycogen synthase kinase-3β(GSK-3β)).Compared with controls,there was no obvious bone loss in the OB mice,and the stiffness of the femur was increased significantly.Compared with summer active squirrels,bone formation was enhanced but the mechanical properties did not change in the PRE group squirrels.In OB mice,western blots showed significantly increased expression levels of all proteins except RunX2,OPG,and Ptch1.PRE ground squirrels showed significantly increased expression of most proteins except OCN and Ptch1,which decreased significantly,and P-β-catenin and OPG,which did not change.In conclusion,for non-hibernating mice,moderate obesity had a certain protective effect on bones,demonstrating two-way regulation,increasing both bone loss and bone formation.For pre-hibernating ground squirrels,the healthy obesity acquired before hibernation had a positive effect on the microstructure of bones,and also enhanced the expression levels of proteins related to bone formation,bone resorption,and Wnt signaling. | Xuli GAO Shenyang SHEN Qiaohua NIU Weilan MIAO Yuting HAN Ziwei HAO Ning AN Yingyu YANG Yu ZHANG Han ZHANG Kenneth BSTOREY Hui CHANG | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，12： | 0 |

| 18 | Structural,volumetric and water retention behaviors of a compacted clay upon saline intrusion and freeze-thaw cycles显示文摘This study investigates the evolution of the structural,volumetric and water retention behaviors of a compacted clay during soaking and desiccation considering the influences of freeze-thaw(FT)cycles and saline intrusion.Compacted specimens were subjected to different FT cycles and then submerged in NaCl solution with different concentrations to facilitate the saline intrusion and measure the swelling behaviors.Shrinkage curve and filter paper tests were thereafter performed to reveal the clay’s volumetric and water-retention characteristics during desiccation.Mercury intrusion porosimetry and field emission scanning electron microscopy tests were conducted to observe the evolution of the clay’s microstructure.Experimental results show that the clay’s micropores decrease and macropores increase after FT cycles,which is associated with the migration of water,growth of ice crystals,and development of FT-induced cracks during FT cycles.Similar observations were obtained from specimens after the saline intrusion,which is attributed to the osmotic and osmotically-induced consolidation.FT-induced cracks significantly reduce the clay’s swelling and shrinkage potentials.FT cycles result in the shrinkage of micropores which leads to a reduction in the water retention capacity in the low suction range(capillary regime).The salinization suppresses the swelling of the clay and prolongs its primary and secondary swelling stages.The shrinkage potential initially increases and then decreases with increasing saline concentration.Salinization has significant influences on the osmotic suction and thus alters the clay’s water-retention curves in terms of total suction.It demonstrates little impact on the clay’s water-retention curves in terms of matric suction. | Jianguo Lin Weilie Zou Zhong Han Ziwei Zhang Xiequn Wang | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，3： | 0 |
| 19 | Light-Harvesting Artificial Cells for the Generation of ATP and NADPH显示文摘The bottom-up construction of self-powered artificial cells is significant to understand the energy supply and metabolism of nature cells.Here,we demonstrate an efficient manner to build thylakoid-containing artificial cells,which continuously convert light energy into chemical energy to supply adenosine 5'-triphosphate(ATP)under light illumination.The production of ATP supplies energy to promote the biological enzyme cascade reactions,where glucose is transformed into glucose 6-phosphate(G6P)under the catalysis of hexokinase(HK).G6P was further converted to gluconolactone 6-phosphate(PG)in the presence of 6-phosphate dehydrogenase(G6PDH),meanwhile NADP^(+) was converted to nicotinamide adenine dinucleotide phosphate(NADPH).The self-powered artificial cells were demonstrated to generate ATP and NADPH successively,which provided a way for building more complicated artificial cells. | Ziwei Su Xiangxiang Zhang Weichen Wang Mingdong Dong Xiaojun Han | 2023 | Chinese Journal of Chemistry2023，41，1： | 0 |
| 20 | Adsorption Site Regulations of[W–O]‑Doped CoP Boosting the Hydrazine Oxidation‑Coupled Hydrogen Evolution at Elevated Current Density显示文摘Hydrazine oxidation reaction(HzOR)assisted hydrogen evolution reaction(HER)offers a feasible path for low power consumption to hydrogen production.Unfortunately however,the total electrooxidation of hydrazine in anode and the dissociation kinetics of water in cathode are critically depend on the interaction between the reaction intermediates and surface of catalysts,which are still challenging due to the totally different catalytic mechanisms.Herein,the[W–O]group with strong adsorption capacity is introduced into CoP nanoflakes to fabricate bifunctional catalyst,which possesses excellent catalytic performances towards both HER(185.60 mV at 1000 mA cm^(−2))and HzOR(78.99 mV at 10,00 mA cm^(−2))with the overall electrolyzer potential of 1.634 V lower than that of the water splitting system at 100 mA cm^(−2).The introduction of[W–O]groups,working as the adsorption sites for H2O dissociation and N2H4 dehydrogenation,leads to the formation of porous structure on CoP nanoflakes and regulates the electronic structure of Co through the linked O in[W–O]group as well,resultantly boosting the hydrogen production and HzOR.Moreover,a proof-of-concept direct hydrazine fuel cell-powered H_(2) production system has been assembled,realizing H_(2)evolution at a rate of 3.53 mmol cm^(−2)h^(−1)at room temperature without external electricity supply. | Ge Meng Ziwei Chang Libo Zhu Chang Chen Yafeng Chen Han Tian Wenshu Luo Wenping Sun Xiangzhi Cui Jianlin Shi | 2023 | Nano-Micro Letters2023，15，11： | 0 |
