1Synthesis and characterization of Sb-doped SnO_2-(CeO_2-TiO_2) composite thin films deposited on glass substrates for antistatic electricity and UV-shielding显示文摘Sb-doped SnO2(ATO)-(CeO2-TiO2) thin Films were deposited on glass substrates using the mixed solution including CeO2-TiO2 precursor and ATO particles by sol-gel dip coating process.ATO particles were prepared using low-temperature hydrothermal process.The mixed molar ratio of ATO to(CeO2-TiO2) vs the properties of CeO2-TiO2 thin film was investigated.The optical properties of the films were characterized by UV-visible transmission and infrared reflection spectra,the sheet resistance of ATO particles and films were measured by rubber sheeter(MYI-50) and four-point probe(HisuperGroup Inc,SDY-5),the surface morphology and structure of the films were analyzed using 3D Digitale Mikroskop and X-ray diffraction(XRD),respectively.The results showed that the ATO precursor solution lost weight completely at about 500 oC,and the ATO particles was obtained,which indicated the same rutile lattice structure as SnO2.The glass substrates coated with ATO-(CeO2-TiO2) thin films showed better properties in antistatic electricity(104-106 Ω/),shielding UV(almost 100%),visible light transmission(70%) and infrared reflection(>30%).WU Shuo1,ZHAO Qingnan1,MIAO Dengkui1,DONG Yuhong2(1.Key Laboratory for Silicate Materials Science and Engineering of Ministry of Education,Wuhan University of Technology,Wuhan 430070,China 2.Jiangsu Xiuqiang Glasswork CO.,Ltd.,Suqian 223800,China) 2010Journal of Rare Earths2010,28,S1:14
2PEEK modified PLA shape memory blends:towards enhanced mechanical and deformation properties显示文摘Polylactic acid(PLA)is one of the most promising shape memory polymers with outstanding biocompatibility,while poly(ether ether ketone)(PEEK)is a special engineering plastic with excellent mechanical performance.In this work,PEEK was selected to modify PLA,and a series of PLA blended with different PEEK contents(PLA/PEEK blends)were obtained.The effects of PEEK on thermodynamic,mechanical and shape memory properties of PLA/PEEK blends were investigated.The results showed that the thermal stabillity of the PL A/PEEK blend was improved with the PEEK content increase.The tensile strength reached the highest value of 20.6 MPa when the PEEK content was 10%.While the best shape memory performance occurred with the PEEK content of 15%,the shape recovery time was less than 2 s,and the shape fixation/recovery ratio was more than 99%.Furthermore,the programmable mimetic flower opening process was achieved by using PLA/PEEK blends with different PEEK content ratios.The above results indicated that the blend of an appropriate proportion of PEEK had positive effects on mechanical and deformation performances of PLA.Lan ZHANG Zhaohua LIN Qiang ZHOU Suqian MA Yunhong LIANG Zhihui ZHANG 2020Frontiers of Materials Science2020,14,2:8

54D printing of PLA/PCL shape memory composites with controllable sequential deformation显示文摘Shape memory polymers(SMPs)are a promising class of materials for biomedical applications due to their favorable mechanical properties,fast response,and good biocompatibility.However,it is difficult to achieve controllable sequential shape change for most SMPs due to their high deformation temperature and the simplex deformation process.Herein,shape memory composites based on polylactic acid(PLA)matrix and semi-crystalline linear polymer polycaprolactone(PCL)are fabricated using 4D printing technology.Compared with pure PLA,with the rise of PCL content,the 4D-printed PLA/PCL composites show decreased glass transition temperature(Tg)from 67.2 to 55.2°C.Through the precise control of the deformation condition,controllable sequential deformation with an outstanding shape memory effect can be achieved for the PLA/PCL shape memory composites.The response time of shape recovery is less than 1.2 s,and the shape fixation/recov-ery rates are above 92%.In order to simulate sequential petal opening and sequential drug releasing effects,a double-layer bionic flower and a drug release device,respectively,are presented by assembling PLA/PCL samples with different PLA/PCL ratios.The results indicate the potential applications of 4D-printed PLA/PCL composites in the field of bio-inspired robotics and biomedical devices.Suqian Ma Zeyu Jiang Meng Wang Lan Zhang Yunhong Liang Zhihui Zhang Lei Ren Luquan Ren 2021Bio-Design and Manufacturing2021,4,4:2

9High-performance Multilayer Flexible Piezoresistive Pressure Sensor with Bionic Hierarchical and Anisotropic Structure显示文摘Flexible pressure sensor that enables detection of multimodal signals has greater advantages in human–computer interaction,medical/health care,and other applications.To make a versatile flexible pressure sensor,hierarchical and anisotropy structure are key features to improve sensing performance and realize multi-signal detection.However,traditional flexible sensors usually have narrow linear range and single signal detection capability.Herein,a highly sensitive flexible piezoresistive pressure sensor which has broad linear range of pressure is developed by replicating one dimensional microstructures from reed leaf and using multilayer superposition of micropatterned polydimethylsiloxane(m-PDMS).Through superposing 4 layers of parallel micropatterned constructive substrates,the multilayer piezoresistive pressure sensor exhibits a high sensitivity of 2.54 kPa?1,a fast response time of 30 ms,and a broad linear range of 107 kPa.The flexible piezoresistive pressure sensor is also highly robust:there is no fatigue after testing for at least 1000 cycles.Due to the specific anisotropy of the micro-structure,the sensor can measure the tangential force in different directions.It permits multimode signal detection,including pressure,tangential force,and deformation.The versatile flexible pressure sensor enables effective monitoring of multisignals,it reveals great potential for medical and health care,flexible human–computer interaction,and intelligent robot.Meng Wang Yue Yu Yunhong Liang Zhiwu Han Chunbao Liu Suqian Ma Zhaohua Lin Lei Ren 2022Journal of Bionic Engineering2022,19,5:1
10Research on Landscape Optimization Design in Urban Waterfront Area——A Case Study of Jinghang Grand Canal in Suqian City of China显示文摘It could find from the survey and analysis that there existed many problems in landscape status of the west bank of Jinghang Grand Canal in Suqian City.For example,land function was scattered,eco-environment was poor,facilities were incomplete and road system was not perfect.Guided by the principle for landscape planning and design of waterfront area,some suggestions had been proposed from the perspective of the design of ecological plants community,design of road transport network,revetment management,control of waterfront buildings,and landscape node design,so as to construct the west bank of Jinghang Grand Canal into the most lively,charming and characteristic waterfront area in Suqian City.SHEN Huixin(Suqian College,Suqian,Jiangsu 223800,China) 2012Journal of Landscape Research2012,4,7:1
11Effects of shrub-grass patterns on soil detachment and hydraulic parameters of slope in the Pisha sandstone area of Inner Mongolia,China显示文摘The characteristics of soil holding capacity for different shrub-grass patterns are important to research the mechanisms regulating vegetation on slopes.The objective of this study was to describe the characteristics and mecha-nisms of soil erosion and hydraulic parameters under differ-ent vegetation patterns in the Pisha sandstone area of Inner Mongolia on lands of 8°slope gradient.We carried out field scouring experiments on five different shrub-grass patterns as treatments,viz no shrubs(GL),shrubs on the upper part of the slope(SU),middle part of the slope(SM)and lower part of the slope(SL).We designated bare slope(BL)as the control.We employed three different water flow rates(15,20,30 L·min^(−1)).Our results showed that the contribution of plant root systems to slope sediment reduction ranged from 64 to 84%.The root systems proved to be the main contributing factor to reduction of erosion by vegetation.The relationship between soil detachment rate,stream flow power,and flow unit stream power under different scouring discharge rates showed that soil detachment declined in rank order as:BL>GL>SU>SM>SL.The SL pat-tern had the lowest soil detachment rate(0.098 g·m^(−2)·s^(−1)),flow stream power(2.371 W·m^(−2)),flow unit stream power(0.165 m·s^(−1))and flow shear stress(16.986 Pa),and proved to be the best erosion combating pattern.The results of decision coefficient and path analysis showed that stream power was the most important hydraulic parameter for describing soil detachment rate.The combination of stream power and shear stress,namely Dr=0.1ω−0.03τ−0.56(R^(2)=0.924),most accurately simulated the soil detachment characteristics on slopes.Our study suggests that the risk of soil ero-sion can be reduced by planting shrub-grass mixes on these slopes.Under the conditions of limited water resources and economy,the benefit of sediment reduction can be maxi-mized by planting shrubbery on the lower parts of slopes.Peng Chen Jianying Guo Tiegang Zhang Zhi Dong Hongli Li Suqian Qiu Xiaoxue Chen 2022Journal of Forestry Research2022,33,2:1

13A cyanostilbene-based molecule with aggregation-induced emission properties: amplified spontaneous emission, protonation effect and electroluminescence显示文摘A terpyridine-substituted cyanostilbene derivative(Z)-2-(4′-([2,2′:6′,2″-terpyridin]-4′-yl)-[1,1′-biphenyl]-4-yl)-3-phenylacrylonitrile(CNSTPy) was synthesized and characterized. The compound exhibits remarkable aggregation-induced emission phenomenon and its single crystal shows a blue emission with fluorescent efficiency as high as 45%. Based on its aggregation state behavior, multiple applications towards exploring its lasing, fluorescence switching and electroluminescence properties were realized. Amplified spontaneous emission(ASE) was observed from the crystal and verified by the variable pump strip method, with a threshold value of ~1.5 m J cm^(-2). The protonation/deprotonation processes accompanied by the formation of different molecular aggregation structure result in the distinct blue and yellow emissions. Additionally, the molecule also shows a moderate electroluminescence performance.Yujie Dong Suqian Ma Xiaoyu Zhang Jingyu Qian Nianyong Zhu Bin Xu Cheuk-Lam Ho Wenjing Tian Wai-Yeung Wong 2019Science China Chemistry2019,62,2:1
14Bioinspired flexible piezoresistive sensor for high-sensitivity detection of broad pressure range显示文摘The human skin has the ability to sense tactile touch and a great range of pressures.Therefore,in prosthetic or robotic systems,it is necessary to prepare pressure sensors with high sensitivity in a wide measurement range to provide human-like tactile sensation.Herein,we developed a flexible piezoresistive pressure sensor that is highly sensitive in a broad pressure range by using lotus leaf micropatterned polydimethylsiloxane and multilayer superposition.By superposing four layers of micropatterned constructive substrates,the multilayer piezoresistive pressure sensor achieves a broad pressure range of 312 kPa,a high sensitivity of 2.525 kPa^(−1),a low limit of detection(LOD)of<12 Pa,and a fast response time of 45 ms.Compared with the traditional flexible pressure sensor,the pressure range of this sensor can be increased by at least an order of magnitude.The flexible piezoresistive pressure sensor also shows high robustness:after testing for at least 1000 cycles,it shows no sign of fatigue.More importantly,these sensors can be potentially applied in various human motion detection scenarios,including tiny pulse monitoring,throat vibration detection,and large under-feet pressure sensing.The proposed fabrication strategy may guide the design of other kinds of multifunctional sensors to improve the detection performance.Meng Wang Hao Zhang Han Wu Suqian Ma Lei Ren Yunhong Liang Chunbao Liu Zhiwu Han 2023Bio-Design and Manufacturing2023,6,3:1

16Nursing perspective of Guidelines for Diagnosis and Treatment of Gout with Integrated Traditional Chinese and Western Medicine显示文摘Gout is a common rheumatism and its long-term recurrent attacks can cause joint destruction and deformity,even disability,which seriously affects the quality of life of patients.Chinese medicine plays a unique advantage in the treatment and rehabilitation of gout.To further standardize the diagnosis and treatment of gout with integrated traditional Chinese and Western medicine,the Chinese Association of Integrative Medicine issued the Guidelines for Diagnosis and Treatment of Gout with Integrated Traditional Chinese and Western Medicine in August 2021.Expert recommendations were made on the etiology and pathogenesis;diagnosis and classification standards;patient health management;and integrated traditional Chinese and Western medicine treatment,prevention,and nursing of gout.This article interprets the guidelines from the nursing point of view,focusing on the detailed explanation of diet care,functional exercise,and appropriate techniques of traditional Chinese medicine for gout,in order to provide better clinical reference for high-quality nursing services for gout patients.Suqian LI Chun WANG Lin LU Ling TANG Huaxin WANG 2022Journal of Integrative Nursing2022,4,3:0
17Photo-induced phosphorus radical involved semipinacol rearrangement reaction:Highly synthesis ofγ-oxo-phosphonates显示文摘Hydroxyphosphoric acids display the unique biological activities,and they have some attractive prospects as clinical drug moleculars.Herein,a new approach for the synthesis ofγ-oxo-phosphonates(the precursor of hydroxyphosphoric acid)has been established through the semipinacol rearrangement tactic involved the photo-induced phosphorus radical process.Most important,this transformation is avoid of the external oxidants,and occurs very well under the sunlight irradiation,meanwhile theγ-oxo-phosphonate was easily derivatized to obtainγ-hydroxyphosphoric acid,thus highlights the synthesis value of this method.Chunhai Wang Xiaoling Huang Xueting Liu Suqian Gao Bin Zhao Shangdong Yang 2020Chinese Chemical Letters2020,31,3:0
18Organic molecular aggregates:From aggregation structure to emission property显示文摘Organic molecular aggregates have attracted widespread attention over the past decade owing to their unique optoelectronic properties in the aggregate state,which mainly involves the effects of aggregation structure as well as molecular packing mode.Although many examples of H-and J-aggregates defined by molecular exciton model have been found,there are also other types of unconventional aggregates,especially for aggregation-induced emission(AIE)system.In this review,the recent progress of some examples of basic and novel aggregate forms,as well as coassembled forms,presenting distinctive optical features,such as optical waveguide and polarization emission,polymorph-dependent emission and stimuli-responsive luminescence are presented.The systematic insight into the relationship between the aggregation structure and emission property is discussed.Guidelines are therefore anticipated and will direct the future preprogramming molecular design so as to fine-tune the emission feature through a specific aggregation model for developing organic molecular aggregates with desirable optoelectronic properties.Suqian Ma Sijia Du Guocui Pan Shuting Dai Bin Xu Wenjing Tian 2021Aggregate2021,2,4:0

20Molecular crystals based on 9,10-distyrylanthracene derivatives with high solid state fluorescence efficiency and uniaxial orientation induced by supramolecular interactions显示文摘Two 9,10-distyrylanthracene (DSA) derivatives CNDSA and t-BUDSA were designed and synthesized, and their photophysical properties and crystal structures were investigated. Compared to DSA, the maximum emission peaks of the two compounds showed red-shift not only in THF solution, but also in crystals, because the introduction of electron-withdrawing substituents to DSA leads to more dispersion of the electrons in the molecules. The two crystals of CNDSA and t-BUDSA show strong fluores- cence with the efficiency F of 45% and 33%, respectively, which may be resulted from no obvious-interactions between molecules inside the crystal due to the large distance between the two adjacent molecules and nearly no overlap between the central anthracene planes. The analysis of crystal structures of the two compounds indicated that the molecules are arranged in the same conformation and orientation in their crystals, i.e. uniaxially oriented packing crystal, because of the supramolecular interac- tion of CH/ in the two crystals and additional C-H···N interactions in CNDSA.CHEN JinLong MA SuQian XU Bin ZHANG JiBo DONG YuJie TIAN WenJing 2013Chinese Science Bulletin2013,58,22:0
