| 1 | Photo-controllable room-temperature phosphorescence of organic photochromic polymers based on hexaarylbiimidazole显示文摘Pure organic room-temperature phosphorescent(RTP)materials have been attracting widespread attention due to the unique properties and broad applications.However,RTP materials with the adjustable photochromic property are still a challenge.Based on this,two polymers containing hexaarylbiimidazole are strategically designed with dual emission of both fluorescence and phosphorescence.Furthermore,both polymers show sensitive photochromic responses from faint yellow to brown upon exposure to ultraviolet light.This study can enrich pure organic luminescent systems and provide new ideas for functional RTP materials. | Yuanhao Li Fan Gu Bingbing Ding Lei Zou Xiang Ma | 2021 | Science China Chemistry2021，64，8： | 2 |
| 2 | Photo-thermoelectric effect induced electricity in stretchable graphene-polymer nanocomposites for ultrasensitive strain sensing显示文摘Stretchable strain sensors play an increasingly important role in artificial intelligent devices.However,high-performanee strain sensors havebeen slowly developed owing to the harsh requirement of self-powered function,long cycle life and high resolution.Here,we report aself-powered stretchable graphene-ecoflex composite strain sensor based on photo-thermoelectric(PTE)effect induced electricity.Thedevice exhibits a high strain sensitivity of-0.056 In(nA)/%with strains ranged from 0%to 20%under 980 nm light illumination,where thestrain sensitivity can be found to in crease with in creasi ng light inte nsity.The strain sensor maintains outstanding dyn amic stability un derperiodic strains ranged from 0 to 100%in 100 cycles.The sensing resolution can be as high as 0.5%with both the response and recovery timeof less than 0.6 s.It can precisely monitor human joint motions and stretchable strains by implanting the device in pork. | Ding Zhang Yiding Song Lu Ping Suwen Xu De Yang Yuanhao Wang Ya Yang | 2019 | Nano Research2019，12，12： | 2 |
| 3 | Comparative study of tribological properties of insulated and conductive polyimide composites显示文摘Insulated polyimide(PI)composites filled with short glass fibers(SGF),polytetrafluoroethylene(PTFE),SiO2,and polyphenylene(PPL)are specially designed,prepared,and the tribological properties are systematically investigated with references to the special requirements for frictional materials used in ultrasonic motors.The hardness and thermal decomposition temperature of the insulated PI composites are comparable to that of conductive PI composites.However,these insulated materials present excellent friction and wear performance,especially under high loads and speeds.Scanning electron microscopy(SEM)analysis of the worn surface indicates that adhesive and fatigue wear dominate the wear mechanisms. | Jingfu SONG Yuanhao YU Gai ZHAO Jinhao QIU Qingjun DING | 2020 | Friction2020，8，3： | 1 |
| 4 | Single-cell RNA landscape of the special fiber initiation process in Bombax ceiba显示文摘As a new source of natural fibers,the Bombax ceiba tree can provide thin,light,extremely soft and warm fiber material for the textile industry.Natural fibers are an ideal model system for studying cell growth and differentiation,but the molecular mechanisms that regulate fiber initiation are not fully understood.In B.ceiba,we found that fiber cells differentiate from the epidermis of the inner ovary wall.Each initiated cell then divides into a cluster of fiber cells that eventually develop into mature fibers,a process very different from the classical fiber initiation process of cotton.We used high-throughput single-cell RNA sequencing(scRNA-seq)to examine the special characteristics of fiber initiation in B.ceiba.A total of 15567 high-quality cells were identified from the inner wall of the B.ceiba ovary,and 347 potential marker genes for fiber initiation cell types were identified.Two major cell types,initiated fiber cells and epidermal cells,were identified and verified by RNA in situ hybridization.A developmental trajectory analysis was used to reconstruct the process of fiber cell differentiation in B.ceiba.Comparative analysis of scRNAseq data from B.ceiba and cotton(Gossypium hirsutum)confirmed that the additional cell division process in B.ceiba is a novel species-specific mechanismfor fiber cell development.Candidate genes and key regulators that may contribute to fiber cell differentiation and division in B.ceiba were identified.This work reveals gene expression signatures during B.ceiba fiber initiation at a single-cell resolution,providing a new strategy and viewpoint for investigation of natural fiber cell differentiation and development. | Yuanhao Ding Wei Gao Yuan Qin Xinping Li Zhennan Zhang Wenjie Lai Yong Yang Kai Guo Ping Li Shihan Zhou Haiyan Hu | 2023 | Plant Communications2023，4，5： | 0 |
| 5 | Improvement Strategies of Flood Control Landscape in Suburban Villages and Towns from the Perspective of Aquaphilia and Livability显示文摘In the context of urban and rural integrated development, many suburban villages and towns are still threatened by both urbanization and natural disasters. In order to explore the improvement strategies of flood control landscape integrating water ecology, water safety, water culture and water landscape, the Luozhou Ancient Town by the Wulong River in Fuzhou City was taken as an example, and the concept of pluralistic symbiosis from the perspective of aquaphilia and livability was proposed through field investigation, data monitoring, site analysis and planning, that is, while retaining the positive attributes of “boundary”, its negative limitation of “pluralistic” space is broken, so as to establish a pluralistic and symbiotic environment with aquaphilia and livability. It can not only effectively alleviate the contradictions between urban and rural areas, between water and land, and between old and new cultures, but also activate the vitality of suburban villages and towns, providing a new idea for the improvement of flood control landscape. | DING Huangjie YAN Chen FANG Cheng ZHANG Shijie LV Yuanhao | 2022 | Journal of Landscape Research2022，14，6： | 0 |
| 6 | A NOVEL SWEPT LASER SOURCE BASED ON COMBINED TUNABLE FILTERS FOR OCT显示文摘A novel broad tunable bandwidth and narrow instantaneous line-width linear swept laser source using combined tunable filters working at 1,300 nm center wavelength is proposed.The combined filters consist of a fiber FabryPerot tunable filter and a tunable filter based on diffractive grating with scanning polygon mirror.In contrast to traditional method using single tunable filter,the trade-off between bandwidth and instantaneous line-width is alleviated.Parallel implementation of two semiconductor optical amplifiers with different wavelength range is adopted in the laser resonator for broadband light amplification.The Fourier domain mode locking swept laser source with combined tunable filters offers broadband tunable range with narrow instantaneous line-width,which is especially benefiting for high-quality optical frequency domain imaging.The proposed Fourier domain mode locking swept laser source provides a tuning range of 160 nm with instantaneous line-width of about 0.01nm at sweeping rate of 15 kHz,a finesse of 16,000 is thus achieved. | MINGHUI CHEN ZHIHUA DING LING WANG TONG WU YUANHAO TAO | 2011 | Journal of Innovative Optical Health Sciences2011，4，1： | 0 |
| 7 | Holocene Hydroclimatic Variations in the Asian Drylands:Current Understanding and Future Perspectives显示文摘0 INTRODUCTION.The intensification of global warming is generating increasing risks to human society and sustainable development,which are of growing concern to the international scientific community and policymakers(Sun,2023).The ecosystems of the Asian drylands are fragile and highly sensitive to global changes;moreover,while these drylands are the most important areas of oasis agriculture on Earth,their water resources are being adversely impacted by ongoing climate change(Zhang et al.,2023).Hence,an improved understanding of the patterns of climate change in this region is important and attracting increasing research attention. | Guoqiang Ding Shengqian Chen Yuanhao Sun Shuai Ma Jianhui Chen | 2024 | Journal of Earth Science2024，35，1： | 0 |
