| 1 | Urine-derived stem cells:A novel and versatile progenitor source for cell-based therapy and regenerative medicine显示文摘Engineered functional organs or tissues,created with autologous somatic cells and seeded on biodegradable or hydrogel scaffolds,have been developed for use in individualswith tissue damage suffered fromcongenital disorders,infection,irradiation,or cancer.However,in those patients,abnormal cells obtained by biopsy fromthe compromised tissue could potentially contaminate the engineered tissues.Thus,an alternative cell source for construction of the neo-organ or functional recovery of the injured or diseased tissues would be useful.Recently,we have found stem cells existing in the urine.These cells are highly expandable,and have self-renewal capacity,paracrine properties,and multi-differentiation potential.As a novel cell source,urine-derived stem cells(USCs)provide advantages for cell therapy and tissue engineering applications in regeneration of various tissues,particularly in the genitourinary tract,because they originate from the urinary tract system.Importantly,USCs can be obtained via a non-invasive,simple,and low-cost approach and induced with high efficiency to differentiate into three dermal cell lineages. | Deying Zhang Guanghui Wei Peng Li Xiaobo Zhou Yuanyuan Zhang | 2014 | Genes & Diseases2014，1，1： | 34 |
| 2 | A closed-loop process for recycling LiNi_xCo_yMn_((1-x-y))O_2 from mixed cathode materials of lithium-ion batteries显示文摘With the rapid development of consumer electronics and electric vehicles(EV), a large number of spent lithium-ion batteries(LIBs) have been generated worldwide. Thus, effective recycling technologies to recapture a significant amount of valuable metals contained in spent LIBs are highly desirable to prevent the environmental pollution and resource depletion. In this work, a novel recycling technology to regenerate a LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2 cathode material from spent LIBs with different cathode chemistries has been developed. By dismantling, crushing,leaching and impurity removing, the LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2(selected as an example of LiNi_xCo_yMn_(1-x-y)O_2) powder can be directly prepared from the purified leaching solution via co-precipitation followed by solid-state synthesis. For comparison purposes, a fresh-synthesized sample with the same composition has also been prepared using the commercial raw materials via the same method. X-ray diffraction(XRD), scanning electron microscopy(SEM) and electrochemical measurements have been carried out to characterize these samples. The electrochemical test result suggests that the re-synthesized sample delivers cycle performance and low rate capability which are comparable to those of the freshsynthesized sample. This novel recycling technique can be of great value to the regeneration of a pure and marketable LiNi_xCo_yMn_(1-x-y)O_2 cathode material with low secondary pollution. | Rujuan Zheng Wenhui Wang Yunkun Dai Quanxin Ma Yuanlong Liu Deying Mu Ruhong Li Jie Rena Changsong Dai | 2017 | Green Energy & Environment2017，2，1： | 11 |
| 3 | Effect of discrete fibre reinforcement on soil tensile strength显示文摘The tensile behaviour of soil plays a significantly important role in various engineering applications.Compacted soils used in geotechnical constructions such as dams and clayey liners in waste containment facilities can suffer from cracking due to tensile failure.In order to increase soil tensile strength,discrete fibre reinforcement technique was proposed.An innovative tensile apparatus was developed to determine the tensile strength characteristics of fibre reinforced soil.The effects of fibre content,dry density and water content on the tensile strength were studied.The results indicate that the developed test apparatus was applicable in determining tensile strength of soils.Fibre inclusion can significantly increase soil tensile strength and soil tensile failure ductility.The tensile strength basically increases with increasing fibre content.As the fibre content increases from 0%to 0.2%,the tensile strength increases by65.7%.The tensile strength of fibre reinforced soil increases with increasing dry density and decreases with decreasing water content.For instance,the tensile strength at a dry density of 1.7 Mg/m^3 is 2.8times higher than that at 1.4 Mg/m^3.It decreases by 30%as the water content increases from 14.5%to20.5%.Furthermore,it is observed that the tensile strength of fibre reinforced soil is dominated by fibre pull-out resistance,depending on the interfacial mechanical interaction between fibre surface and soil matrix. | Jian Li Chaosheng Tang Deying Wang Xiangjun Pei Bin Shi | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014，6，2： | 8 |

| 9 | Monitoring subsidence rates along road network by persistent scatterer SAR interferometry with high-resolution TerraSAR-X imagery显示文摘Ground subsidence is one of the key factors damaging transportation facilities,e.g.,road networks consisting of highways and railways.In tiiis paper,we propose to apply the persistent scatterer synthetic aperture radar interferometry(PS-InSAR)approach mat uses highresolution TerraSAR-X(TSX)imagery to extract the regional scale subsidence rates(i.e.,average annual subsidence in mm/year)along road networks.The primary procedures involve interferometric pair selection,interferogram generation,persistent scatterer(PS)detection,PS networking,phase parameterization,and subsidence rate estimation.The Xiqing District in southwest Tianjin(China)is selected as the study area.This district contains one railway line and several highway lines.A total of 15TSX images covering this area between April 2009 and June 2010 are utilized to obtain the subsidence rates by using the PS-InSAR(PSI)approach.The subsidence rates derived from PSI range from—68.7 to—1.3 mm/year.These findings show a significantly uneven subsidence pattern along the road network.Comparison between the PSI-derived subsidence rates and the leveling data obtained along the highways shows that the mean and standard deviation(SD)of the discrepancies between die two types of subsidence rates are 0.1 and±3.2 mm/year,respectively.The results indicate that the high-resolution TSX PSI is capable of providing comprehensive and detailedsubsidence information regarding road networks with millimeter-level accuracy.Further inspections under geological conditions and land-use categories in the study area indicate that the observed subsidence is highly related to aquifer compression due to groundwater pumping.Therefore,measures should be taken to mitigate groundwater extraction for the study area. | Bing Yu Guoxiang Liu Rui Zhang Hongguo Jia Tao Li Xiaowen Wang Keren Dai Deying Ma | 2013 | Journal of Modern Transportation2013，21，4： | 4 |
| 10 | Dopant-free hole transporting materials with supramolecular interactions and reverse diffusion for efficient and modular p-i-n perovskite solar cells显示文摘The rational design of dopant-free organic hole-transporting layer(HTL) materials is still a challenge for realizing high-efficient and stable p-i-n planar perovskite solar cells(pero-SCs). Here, we synthesized two π-conjugated small-molecule HTL materials through tailoring the backbone and conjugated side chain to carefully control molecular conformation. The resultant BDT-TPAs Th containing a planar fused benzo[1,2-b:4,5-b′]dithiophene(BDT) core and a conjugated thiophene side chain showed the planar conformation. X-ray crystallography showed a favorable stacking model in solid states under the parallel-displaced π-πand additional S-π weak-bond supramolecular interactions, thus achieving an obviously increased hole mobility without dopants.As an HTL material in p-i-n planar pero-SCs, the marginal solubility of BDT-TPA-s Th enabled inverse diffusion into the perovskite precursor solution for assisting the subsequent perovskite film growth and passivating the uncoordinated Pb2+ ion defects. As a result, the planar p-i-n pero-SCs exhibited a champion power conversion efficiency(PCE) of 20.5% and enhanced moisture stability. Importantly, the BDT-TPA-s Th HTL material also showed weak thickness-photovoltaic dependence, and the pero-SCs with blade-coated BDT-TPA-s Th as a HTL achieved a 15.30% PCE for the 1-cm2 modularized device. This HTL material design strategy is expected to pave the way toward high-performance, dopant-free and printing large-area planar p-i-n pero-SCs. | Rongming Xue Moyao Zhang Deying Luo Weijie Chen Rui Zhu Yang(Michael)Yang Yaowen Li Yongfang Li | 2020 | Science China Chemistry2020，63，7： | 4 |
| 11 | Approximation for a scheduling problem with application in wireless networks显示文摘A network of many sensors and a base station that are deployed over a region is considered.Each sensor has a transmission range,an interference range and a carrier sensing range,which are r,αr and βr,respectively.In this paper,we study the minimum latency conflict-aware many-to-one data aggregation scheduling problem:Given locations of sensors along with a base station,a subset of all sensors,and parameters r,α and β,to find a schedule in which the data of each sensor in the subset can be transmitted to the base station with no conflicts,such that the latency is minimized.We designe an algorithm based on maximal independent sets,which has a latency bound of(a+19b)R + Δb-a + 5 time slots,where a and b are two constant integers relying on α and β,Δ is the maximum degree of network topology,and R is the trivial lower bound of latency.Here Δ contributes to an additive factor instead of a multiplicative one,thus our algorithm is nearly a constant(a+19b)-ratio. | ZHU QingHua & LI DeYing Key Laboratory of Data Engineering and Knowledge Engineering,MOE,School of Information,Renmin University of China,Beijing 100872,China | 2010 | Science China Mathematics2010，53，6： | 4 |

| 13 | Nonradical-dominated peroxymonosulfate activation through bimetallic Fe/Mn-loaded hydroxyl-rich biochar for efficient degradation of tetracycline显示文摘Biochar-based transition metal catalysts have been identified as excellent peroxymonosulfate(PMS)activators for producing radicals used to degrade organic pollutants.However,the radical-dominated pathways for PMS activation severely limit their practical applications in the degradation of organic pollutants from wastewater due to side reactions between radicals and the coexisting anions.Herein,bimetallic Fe/Mn-loaded hydroxyl-rich biochar(FeMn-OH-BC)is synthesized to activate PMS through nonradical-dominated pathways.The as-prepared FeMn-OH-BC exhibits excellent catalytic activity for degrading tetracycline at broad pH conditions ranging from 5 to 9,and about 85.0%of tetracycline is removed in 40 min.Experiments on studying the influences of various anions(HCO_(3)^(−),NO_(3)^(−),and H_(2)PO_(4)^(−))show that the inhibiting effect is negligible,suggesting that the FeMn-OHBC based PMS activation is dominated by nonradical pathways.Electron paramagnetic resonance measurements and quenching tests provide direct evidence to confirm that 1O2 is the major reactive oxygen species generated from FeMn-OH-BC based PMS activation.Theoretical calculations further reveal that the FeMn-OH sites in FeMn-OH-BC are dominant active sites for PMS activation,which have higher adsorption energy and stronger oxidative activity towards PMS than OH-BC sites.This work provides a new route for driving PMS activation by biochar-based transition metal catalysts through nonradical pathways. | Yihui Li Deying Lin Yongfu Li Peikun Jiang Xiaobo Fang Bing Yu | 2023 | Nano Research2023，16，1： | 3 |
| 14 | Optical and Radiative Properties of Aerosols during a Severe Haze Episode over the North China Plain in December 2016显示文摘The optical and radiative properties of aerosols during a severe haze episode from 15 to 22 December 2016 over Beijing, Shijiazhuang, and Jiaozuo in the North China Plain were analyzed based on the ground-based and satellite data, meteorological observations, and atmospheric environmental monitoring data. The aerosol optical depth at 500 nm was < 0.30 and increased to > 1.4 as the haze pollution developed. The ?ngstr?m exponent was > 0.80 for most of the study period. The daily single-scattering albedo was > 0.85 over all of the North China Plain on the most polluted days and was > 0.97 on some particular days. The volumes of fine and coarse mode particles during the haze event were approximately 0.05–0.21 and 0.01–0.43 μm3, respectively—that is, larger than those in the time without haze. The daily absorption aerosol optical depth was about 0.01–0.11 in Beijing, 0.01–0.13 in Shijiazhuang, and0.01–0.04 in Jiaozuo, and the average absorption ?ngstr?m exponent varied between 0.6 and 2.0. The aerosol radiative forcing at the bottom of the atmosphere varied from –23 to –227, –34 to –199, and –29 to –191 W m–2 for the whole haze period, while the aerosol radiative forcing at the top of the atmosphere varied from –4 to –98, –10 to –51,and –21 to –143 W m–2 in Beijing, Shijiazhuang, and Jiaozuo, respectively. Satellite observations showed that smoke,polluted dust, and polluted continental components of aerosols may aggravate air pollution during haze episodes. The analysis of the potential source contribution function and concentration-weighted trajectory showed that the contribution from local emissions and pollutants transport from upstream areas were 190–450 and 100–410 μg m^(–3), respectively. | Yu ZHENG Huizheng CHE Leiku YANG Jing CHEN Yaqiang WANG Xiangao XIA Hujia ZHAO Hong WANG Deying WANG Ke GUI Linchang AN Tianze SUN Jie YU Xiang KUANG Xin LI Enwei SUN Dapeng ZHAO Dongsen YANG Zengyuan GUO Tianliang ZHAO Xiaoye ZHANG | 2017 | Journal of Meteorological Research2017，31，6： | 2 |
