| 1 | Flexible smart sensing skin for“Fly-by-Feel”morphing aircraft显示文摘Flexible smart sensing skin is a key enabling technology for the future'Fly-by-Feel'control of morphing aircraft.It represents the next-generation skin of aircraft that can exhibit a more powerful sensing function than a conventional one and could be mounted on arbitrary curvilinear surfaces,especially for advanced autonomic,morphing aircraft.Recent significant technical advances in flexible electronics have overcome many historic drawbacks of conventional smart skin,e.g.,only a limited number of discrete block sensors can be integrated due to the inevitable structural damage and heavy guidelines.Herein,we review the key developments in flexible sensors technology and highlight both the state-of-the-art devices and the potential applications for the measurement of aircraft.We begin with the importance of flexible smart skin for morphing aircraft and then expand to the latest progress in various types of flexible sensors.Then we highlight flexible sensors as smart skin to measure aerodynamic parameters and monitor the structural health,and further to achieve the Fly-by-Feel control.Finally,the challenges and opportunities on flexible smart sensing skin are discussed,from the functional design to practical applications. | HUANG YongAn ZHU Chen XIONG WenNan WANG Yu JIANG YongGang QIU Lei GUO DongLiang HOU Chao JIANG Shan YANG ZhaoXi WANG Bo WANG Lu YIN ZhouPing | 2022 | Science China(Technological Sciences)2022，65，1： | 6 |
| 2 | Morphological properties and proliferation analysis of olfactory ensheathing cells seeded onto three-dimensional collagen-heparan sulfate biological scaffolds显示文摘This study aimed to examine the differences in the morphological properties and proliferation of ol-factory ensheathing cells in three-dimensional culture on collagen-heparan sulfate biological scaf-folds and in two-dimensional culture on common flat culture plates.The proliferation rate of olfactory ensheathing cells in three-dimensional culture was higher than that in two-dimensional culture,as detected by an MTT assay.In addition,more than half of the olfactory ensheathing cells subcultured using the trypsinization method in three-dimensional culture displayed a spindly Schwann cell-like morphology with extremely long processes,while they showed a flat astrocyte-like morphology in two-dimensional culture.Moreover,spindle-shaped olfactory ensheathing cells tended to adopt an elongated bipolar morphology under both culture conditions.Experimental findings indicate that the morphological properties and proliferation of olfactory ensheathing cells in three-dimensional culture on collagen-heparan sulfate biological scaffolds are better than those in two-dimensional culture. | Na Liu Zhouping Tang Zhiyuan Yu Minjie Xie Yu Zhang Erfang Yang Shabei Xu | 2012 | Neural Regeneration Research2012，7，16： | 2 |
| 3 | Flexible electronics manufacturing technology and equipment显示文摘Flexible electronics such as mechanically compliant displays,sensors and solar cells,have important applications in the fields of energy,national defence and biomedicine,etc.Various types of flexible electronics have been proposed or developed by the improvements in structural designs,material properties and device integrations.However,the manufacturing of flexible electronics receives little attention,which limits its mass production and industrialization.The increasing demands on the size,functionality,resolution ratio and reliability of flexible electronics bring several significant challenges in their manufacturing processes.This work aims to report the state-of-art technologies and applications of flexible electronics manufacturing.Three key technologies including electrohydrodynamic direct-writing,flip chip and automatic optical inspection are highlighted.The mechanism and developments of these technologies are discussed in detail.Based on these technologies,the present work develops three kinds of manufacturing equipment,i.e.,inkjet printing manufacturing equipment,robotized additive manufacturing equipment,and roll-to-roll manufacturing equipment.The advanced manufacturing processes,equipment and systems for flexible electronics pave the way for applications of new displays,smart sensing skins and epidermal electronics,etc.By reviewing the developments of flexible electronics manufacturing technology and equipment,it can be found that the existing advances greatly promote the applications and commercialization of flexible electronics.Since flexible electronics manufacturing contains many multi-disciplinary problems,the current investigations are confronted with great challenges.Therefore,further developments of the reviewed manufacturing technology and equipment are necessary to break the current limitations of manufacturing resolution,efficiency and reliability. | YIN ZhouPing HUANG YongAn YANG Hua CHEN JianKui DUAN YongQing CHEN Wei | 2022 | Science China(Technological Sciences)2022，65，9： | 1 |
| 4 | Real-time adaptive particle image velocimetry for accurate unsteady flow field measurements显示文摘Almost all conventional open-loop particle image velocimetry(PIV) methods employ fixed-interval-time optical imaging technology and the time-consuming cross-correlation-based PIV measurement algorithm to calculate the velocity field.In this study,a novel real-time adaptive particle image velocity(RTA-PIV) method is proposed to accurately measure the instantaneous velocity field of an unsteady flow field.In the proposed closed-loop RTA-PIV method,a new correlation-filter-based PIV measurement algorithm is introduced to calculate the velocity field in real time.Then,a Kalman predictor model is established to predict the velocity of the next time instant and a suitable interval time can be determined.To adaptively adjust the interval time for capturing two particle images,a new high-speed frame-straddling vision system is developed for the proposed RTA-PIV method.To fully analyze the performance of the RTA-PIV method,we conducted a series of numerical experiments on ground-truth image pairs and on real-world image sequences. | OUYANG ZhenXing YANG Hua LU Jin HUANG YongAn YIN ZhouPing | 2022 | Science China(Technological Sciences)2022，65，9： | 1 |

| 6 | Programmable robotized‘transfer-and-jet’printing for large,3D curved electronics on complex surfaces显示文摘Large,3D curved electronics are a trend of the microelectronic industry due to their unique ability to conformally coexist with complex surfaces while retaining the electronic functions of 2D planar integrated circuit technologies.However,these curved electronics present great challenges to the fabrication processes.Here,we propose a reconfigurable,mask-free,conformal fabrication strategy with a robot-like system,called robotized‘transfer-and-jet’printing,to assemble diverse electronic devices on complex surfaces.This novel method is a ground-breaking advance with the unique capability to integrate rigid chips,flexible electronics,and conformal circuits on complex surfaces.Critically,each process,including transfer printing,inkjet printing,and plasma treating,are mask-free,digitalized,and programmable.The robotization techniques,including measurement,surface reconstruction and localization,and path programming,break through the fundamental constraints of 2D planar microfabrication in the context of geometric shape and size.The transfer printing begins with the laser lift-off of rigid chips or flexible electronics from donor substrates,which are then transferred onto a curved surface via a dexterous robotic palm.Then the robotic electrohydrodynamic printing directly writes submicrometer structures on the curved surface.Their permutation and combination allow versatile conformal microfabrication.Finally,robotized hybrid printing is utilized to successfully fabricate a conformal heater and antenna on a spherical surface and a flexible smart sensing skin on a winged model,where the curved circuit,flexible capacitive and piezoelectric sensor arrays,and rigid digital–analog conversion chips are assembled.Robotized hybrid printing is an innovative printing technology,enabling additive,noncontact and digital microfabrication for 3D curved electronics. | YongAn Huang Hao Wu Chen Zhu Wennan Xiong Furong Chen Lin Xiao Jianpeng Liu Kaixin Wang Huayang Li Dong Ye Yongqing Duan Jiankui Chen Hua Yang Wenlong Li Kun Bai Zhouping Yin Han Ding | 2021 | International Journal of Extreme Manufacturing2021，3，4： | 1 |
| 7 | Transplantation of neural progenitor cells differentiated from adipose tissue-derived stem cells for treatment of sciatic nerve injury显示文摘Objectives: Currently, the clinical repair of sciatic nerve injury remains difficult.Previous studies have confirmed that transplantation of adipose tissue-derived stem cells promotes nerve regeneration and restoration at peripheral nerve injury sites. Methods: In this study, adipose tissue-derived stem cells were induced to differentiate into neural progenitor cells, transfected with a green fluorescent protein-containing lentivirus, and then transplanted into the lesions of rats with sciatic nerve compression injury. Results: Fluorescence microscopy revealed that the transplanted cells survived,migrated, and differentiated in rats. At two weeks post-operation, a large number of transplanted cells had migrated to the injured lesions; at six weeks post-operation, transplanted cells were visible around the injured nerve and several cells were observed to express a Schwann cell marker. Sciatic function index and electrophysiological outcomes of the transplantation group were better than those of the control group. Cell transplantation promoted the recovery of motor nerve conduction velocity and compound muscle action potential amplitude, and reduced gastrocnemius muscle atrophy.Conclusions: Our experimental findings indicate that neural progenitor cells,differentiated from adipose tissue-derived stem cells, are potential seed stem cells that can be transplanted into lesions to treat sciatic nerve injury. This provides a theoretical basis for their use in clinical applications. | Shasha Dong Na Liu Yang Hu Ping Zhang Chao Pan Youping Zhang Yingxin Tang Zhouping Tang | 2016 | Translational Neuroscience and Clinics2016，2，2： | 1 |

| 11 | High-performance porous carbon foams via catalytic pyrolysis of modified isocyanate-based polyimide foams for electromagnetic shielding显示文摘Porous carbon skeletons(PCSs)derived from isocyanate-based aromatic polyimide foams(PIFs)by high-temperature pyrolysis are very promising in the fabrication of high-performance polymer composite foams for electromagnetic interference(EMI)shielding due to their efficient conductive networks and facile preparation process.However,severe volumetric shrinkage and low graphitization degree is not conducive to enhancing the shielding efficiency of the PCSs.Herein,ferric acetylacetonate and carbon-nanotube coating have been introduced in isocyanate-based PIFs to greatly suppress the serious shrinkage during pyrolysis and improve the graphitization degree of the final carbon foams through the Fe-catalytic graphitization process,thereby endowing them with better EMI-shielding performance even at lower pyrolysis temperature compared to the control samples.Moreover,compressible polydimethylsiloxane(PDMS)composite foams with the as-prepared carbon foams as prefabricated PCSs have also been fabricated,which could provide not only stable shielding effectiveness(SE)performance even after a thousand compressions,but also multiple functions of Joule heating,thermal insulation and infrared stealth.This study offers a feasible route to prepare high-performance PCSs in a more energy-efficient manner via PIF pyrolysis,which is very promising in the manufacture of multifunctional conductive polymer composite foams. | Zhouping Sun Bin Shen Yang Li Jiali Chen Wenge Zheng | 2022 | Nano Research2022，15，8： | 1 |
| 12 | Preliminary Study on Heavy Metal Pollution Status of Farmland Soil at Two Sides of Cheng-Guan Expressway显示文摘The heavy metal content of the farmland soil at two sides of Cheng-Guan Expressway is measured to make a preliminary evaluation on its heavy metal pollution status.After digestion and volume fixation of the soil samples collected,measure the Cu,Zn,Cd,Pb and Cr content with atomic absorption spectrophotometry and evaluate the measured data according to Level Two of National Soil Environmental Quality Standard to obtain the contamination status.Cu,Zn and Cd content of the farmland soil for sections of Cheng-Guan Expressway goes beyond Level Two of National Soil Environmental Quality Standard,while the Pb and Cr content meets Level Two of National Soil Environmental Quality Standard.Pb and Cr content of the farmland soil at two sides of Cheng-Guan Expressway is in safe state,while the Cu,Zn and Cd content is in a mild contamination state.Cu,Zn and Cd are the main pollution elements. | Dongli DUAN Shuangyan WANG Zumin ZHANG Zhouping YANG Hua ZHEN | 2013 | Asian Agricultural Research2013，5，8： | 0 |
| 13 | Light quality regulates plant biomass and fruit quality through a photoreceptor-dependent HY5-LHC/CYCB module in tomato显示文摘Increasing photosynthesis and light capture offers possibilities for improving crop yield and provides a sustainable way to meet the increasing global demand for food.However,the poor light transmittance of transparent plastic films and shade avoidance at high planting density seriously reduce photosynthesis and alter fruit quality in vegetable crops,and therefore it is important to investigate the mechanisms of light signaling regulation of photosynthesis and metabolism in tomato(Solanum lycopersicum).Here,a combination of red,blue,and white(R1W1B0.5)light promoted the accumulation of chlorophyll,carotenoid,and anthocyanin,and enhanced photosynthesis and electron transport rates by increasing the density of active reaction centers and the expression of the genes LIGHT-HARVESTING COMPLEX B(SlLHCB)and A(SlLHCA),resulting in increased plant biomass.In addition,R1W1B0.5 light induced carotenoid accumulation and fruit ripening by decreasing the expression of LYCOPENEβ-CYCLASE(SlCYCB).Disruption of SlCYCB largely induced fruit lycopene accumulation,and reduced chlorophyll content and photosynthesis in leaves under red,blue,and white light.Molecular studies showed that ELONGATED HYPOCOTYL 5(SlHY5)directly activated SlCYCB,SlLHCB,and SlLHCA expression to enhance chlorophyll accumulation and photosynthesis.Furthermore,R1W1B0.5 light-induced chlorophyll accumulation,photosynthesis,and SlHY5 expression were largely decreased in the slphyb1cry1 mutant.Collectively,R1W1B0.5 light noticeably promoted photosynthesis,biomass,and fruit quality through the photoreceptor(SlPHYB1 and SlCRY1)-SlHY5-SlLHCA/B/SlCYCB module in tomato.Thus,the manipulation of light environments in protected agriculture is a crucial tool to regulate the two vital agronomic traits related to crop production efficiency and fruit nutritional quality in tomato. | Jiarong Yan Juan Liu Shengdie Yang Chenghao Jiang Yanan Liu Nan Zhang Xin Sun Ying Zhang Kangyou Zhu Yinxia Peng Xin Bu Xiujie Wang Golam Jalal Ahammed Sida Meng Changhua Tan Yufeng Liu Zhouping Sun Mingfang Qi Feng Wang Tianlai Li | 2023 | Horticulture Research2023，10，12： | 0 |
| 14 | A 3D/0D cobalt-embedded nitrogen-doped porous carbon/supramolecular porphyrin magnetic-separation photocatalyst with highly efficient pollutant degradation and water oxidation performance显示文摘A 3D/0D cobalt-embedded nitrogen-doped porous carbon nanocubes(Co-N-C)/supramolecular tetra(4-carboxylphenyl)porphyrin nanocrystals(SA-TCPP)photocatalyst was successfully self-assembled viaπ–πinteraction,hydrogen bonding,and chemical bonding.Co-N-C/SA-TCPP heterostructure exhibited satisfactory visible photocatalytic oxidation performance on pollutant degradation and water evolution.The degradation rates of Co-N-C/ST(30%)composite towards 2,4-dichlorophenol,ofloxacin,and ethylene were10.9,7.2,and 2.1 times faster than SA-TCPP,respectively.The oxygen evolution efficiency was 1.9 times higher than SA-TCPP.The remarkably improved oxidation activities of Co-N-C/SA-TCPP were mainly ascribed to the following reasons:(1)Co-N-C could enhance the light absorption ability of SA-TCPP to produce more photoinduced carriers.(2)The well-developed porosity of Co-N-C could optimize the dispersibility of SA-TCPP to provide more reactive sites and charge separation channels.(3)Theπ–πinteraction between SA-TCPP and Co-N-C was beneficial to interlayer charge mobility,while the embedded cobalt nanoparticles(Co NPs)and N-doped carbon matrix could serve as electron traps to accelerate interfacial electron transfer.Additionally,the ferromagnetic Co NPs endowed Co-N-C/SA-TCPP with magnetic-separation function to promote recyclability in practical application. | Lufang Ning Jing Xu Yang Lou Chengsi Pan Zhouping Wang Yongfa Zhu | 2022 | Journal of Materials Science & Technology2022，，29： | 0 |

| 16 | Atrial of arbidol hydrochloride in adults with COVID-19显示文摘Background: To date, there is no effective medicine to treat coronavirus disease 2019 (COVID-19), and the antiviral efficacy of arbidol in the treatment for COVID-19 remained equivocal and controversial. The purpose of this study was to evaluate the efficacy and safety of arbidol tablets in the treatment of COVID-19.Methods: This was a prospective, open-label, controlled and multicenter investigator-initiated trial involving adult patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients were stratified 1:2 to either standard-of-care (SOC) or SOC plus arbidol tablets (oral administration of 200 mg per time, three times a day for 14 days). The primary endpoint was negative conversion of SARS-CoV-2 within the first week. The rates and 95% confidential intervals were calculated for each variable.Results: A total of 99 patients with laboratory-confirmed SARS-CoV-2 infection were enrolled;66 were assigned to the SOC plus arbidol tablets group, and 33 to the SOC group. The negative conversion rate of SARS-CoV-2 within the first week in patients receiving arbidol tablets was significantly higher than that of the SOC group (70.3% [45/64]vs. 42.4% [14/33];difference of conversion rate 27.9%;95% confidence interval [CI], 7.7%-48.1%;P=0.008). Compared to those in the SOC group, patients receiving arbidol tablets had a shorter duration of clinical recovery (median 7.0 daysvs. 12.0 days;hazard ratio [HR]: 1.877, 95% CI: 1.151-3.060,P=0.006), symptom of fever (median 3.0 daysvs. 12.0 days;HR: 18.990, 95% CI: 5.350-67.410,P<0.001), as well as hospitalization (median 12.5 daysvs. 20.0 days;P<0.001). Moreover, the addition of arbidol tablets to SOC led to more rapid normalization of declined blood lymphocytes (median 10.0 daysvs. 14.5 days;P > 0.05). The most common adverse event in the arbidol tablets group was the elevation of transaminase (5/200, 2.5%), and no one withdrew from the study due to adverse events or disease progression.Conclusions: SOC plus arbidol tablets significantly increase the negative conversion rate of SARS-CoV-2 within the first week and accelerate the recovery of COVID-19 patients. During the treatment with arbidol tablets, we find no significant serious adverse events. | Jingya Zhao Jinnong Zhang Yang Jin Zhouping Tang Ke Hu Hui Sun Mengmeng Shi Qingyuan Yang Peiyu Gu Hongrong Guo Qi Li Haiying Zhang Chenghong Li Ming Yang Nian Xiong Xuan Dong Juanjuan Xu Fan Lin Tao Wang Chao Yang Bo Huang Jingyi Zhang hi Chen Qiong He Min Zhou Jieming Qu | 2022 | Chinese Medical Journal2022，，13： | 0 |
| 17 | Strategies to improve the migration of mesenchymal stromal cells in cell therapy显示文摘Mesenchymal stromal/stem cells(MSCs) are multipotent cells under consideration as a potential new therapy for a variety of inflammatory diseases including certain neurological disorders. It is generally thought that the efficacy of cell therapy in attenuating damage after ischemia, inflammation, or injury depends on the quantity of transplanted cells recruited to the target tissue. However, only a small number of systematically infused MSCs can effectively migrate to target sites, which significantly decreases the efficacy of exogenous cell-based therapy. In this review, we discuss specific factors influencing MSC migration, and summarize current strategies that effectively promote the motility of MSCs. In addition, we describe several protocols to improve the migration of stromal cells into the nervous system and, therefore,enhance the efficiency of engraftment as means of treating neurological disorders. | Gaigai Li Yang Hu Yanfang Chen Zhouping Tang | 2017 | Translational Neuroscience and Clinics2017，3，3： | 0 |
| 18 | Homocysteine impedes neurite outgrowth recovery after intracerebral haemorrhage by downregulating pCAMK2A显示文摘Hyperhomocysteinemia(HHcy)is independently associated with poorer long-term prognosis in patients with intracerebral haemorrhage(ICH);however,the effect and mechanisms of HHcy on ICH are still unclear.Here,we evaluated neurite outgrowth and neurological functional recovery using simulated models of ICH with HHcy in vitro and in vivo.We found that the neurite outgrowth velocity and motor functional recovery in the ICH plus HHcy group were significantly slower than that in the control group,indicating that homocysteine(Hcy)significantly impedes the neurite outgrowth recovery after ICH.Furthermore,phosphoproteomic data and signalome analysis of perihematomal brain tissues suggested that calmodulin-dependent protein kinases 2(CAMK2A)kinase substrate pairs were significantly downregulated in ICH with HHcy compared with autologous blood injection only,both western blot and immunofluorescence staining confirmed this finding.Additionally,upregulation of pCAMK2A significantly increased neurite outgrowth recovery in ICH with HHcy.Collectively,we clarify the mechanism of HHcy-hindered neurite outgrowth recovery,and pCAMK2A may serve as a therapeutic strategy for promoting neurological recovery after ICH. | Guangyu Guo Jingfei Yang Wenliang Guo Hong Deng Haihan Yu Shuang Bai Gaigai Li Yingxin Tang Ping Zhang Yuming Xu Chao Pan Zhouping Tang | 2023 | Stroke & Vascular Neurology2023，8，4： | 0 |
