1Black carbon aerosols and their radiative properties in the Pearl River Delta region显示文摘The climatic and environmental effects of atmospheric aerosols are a hot topic in global science community, and radiative properties of the aerosols are one of the important parameters in assessing climatic change. Here we studied the black carbon concentration and absorption coefficient measured with aethalometers, scattering coefficient measured with nephelometers, and single scattering albedo derived at an atmospheric composition watch station in Guangzhou from 2004 to 2007. Our main results are as follows. The data of black carbon concentration and absorption coefficients measured with instruments cannot be directly used until they are measured in parallel with internationally accepted instruments for comparison, calibration, and reduction. After evaluation of the data, the result shows that the monthly mean of BC concentration varies 3.1―14.8 μg·m-3 and the concentration decreases by about 1 μg·m-3 in average over the four years; It is higher in the dry season with a multi-year mean of 8.9 μg/m3 and lower in the rainy season with a multi-year mean of 8.0 μg·m-3; The extreme maximum of monthly mean concentration occurred in December 2004 and extreme minimum in July 2007, and a 4-year mean is 8.4 μg·m-3. It is also shown that monthly mean scattering coefficient derived varies 129 -565 Mm-1, monthly mean absorption coefficient 32-139 Mm-1, and monthly mean single scattering albedo 0.71-0.91, with annual mean values of 0.80, 0.82, 0.79 and 0.84 for 2004, 2005, 2006 and 2007, respectively. Three instruments were used to take simultaneous measurements of BC in PM10, PM2.5, and PM1 and the results showed that PM2.5 took up about 90% of PM10 and PM1 accounted for about 68% of PM2.5, and BC aerosols are mainly present in fine particulates. The variability of BC concentrations is quite consistent between the Nancun station (141 m above sea level) and the Panyu station (13 m above sea level), which are 8 km apart from each other. The concentration in higher altitude station (Panyu) is consistently lower than the lower altitude station (Nancun), and the difference of annual mean is about 4 μg·m-3.WU Dui MAO JieTai DENG XueJiao TIE XueXi ZHANG YuanHang ZENG LiMin LI Fei TAN HaoBo BI XueYan HUANG XiaoYing CHEN Jing DENG Tao 2009Science China Earth Sciences2009,52,8:58
2Exploration of the formation mechanism and source attribution of ambient ozone in Chongqing with an observation-based model显示文摘An intensive field campaign was conducted in Chongqing during the summer of 2015 to explore the formation mechanisms of ozone pollution. The sources of ozone, the local production rates, and the controlling factors, as well as key species of volatile organic compounds(VOCs), were quantified by integrating a local ozone budget analysis, calculations of the relative incremental reactivity, and an empirical kinetic model approach. It was found that the potential for rapid local ozone formation exists in Chongqing. During ozone pollution episodes, the ozone production rates were found to be high at the upwind station Nan Quan, the urban station Chao Zhan, and the downwind station Jin-Yun Shan. The average local ozone production rate was 30×10^(-9) V/V h^(-1) and the daily integration of the produced ozone was greater than 180×10^(-9) V/V. High ozone concentrations were associated with urban and downwind air masses. At most sites, the local ozone production was VOC-limited and the key species were aromatics and alkene, which originated mainly from vehicles and solvent usage. In addition, the air masses at the northwestern rural sites were NO_x-limited and the local ozone production rates were significantly higher during the pollution episodes due to the increased NOx concentrations. In summary, the ozone abatement strategies of Chongqing should be focused on the mitigation of VOCs. Nevertheless, a reduction in NO_x is also beneficial for reducing the regional ozone peak values in Chongqing and the surrounding areas.SU Rong LU KeDing YU JiaYan TAN ZhaoFeng JIANG MeiQing LI Jing XIE ShaoDong WU YuSheng ZENG LiMin ZHAI ChongZhi ZHANG YuanHang 2018Science China Earth Sciences2018,61,1:24
3Pretreatment with Danhong injection protects the brain against ischemia-reperfusion injury显示文摘Danhong injection(DHI),a Chinese Materia Medica standardized product extracted from Radix Salviae miltiorrhizae and Flos Carthami tinctorii,is widely used in China for treating acute ischemic stroke.In the present study,we explored the neuroprotective efficacy of DHI in a rat model of temporary middle cerebral artery occlusion,and evaluated the potential mechanisms underlying its effects.Pretreatment with DHI(0.9 and 1.8 mL/kg)resulted in a significantly smaller infarct volume and better neurological scores than pretreatment with saline.Furthermore,DHI significantly reduced the permeability of the blood-brain barrier,increased occludin protein expression and decreased neutrophil infiltration,as well as profoundly suppressing the upregulation of matrix metallopeptidase-9 expression seen in rats that had received vehicle.Matrix metallopeptidase-2 expression was not affected by ischemia or DHI.Moreover,DHI(1.8 mL/kg)administered 3 hours after the onset of ischemia also improved neurological scores and reduced infarct size.Our results indicate that the neuroprotective efficacy of DHI in a rat model of cerebral ischemia-reperfusion injury is mediated by a protective effect on the blood-brain barrier and the reversal of neutrophil infiltration.Shaoxia Wang Hong Guo Xumei Wang Lijuan Chai Limin Hu Tao Zhao Buchang Zhao Xiaoxu Tan Feifei Jia 2014Neural Regeneration Research2014,9,15:12
4Exosome-functionalized polyetheretherketone-based implant with immunomodulatory property for enhancing osseointegration显示文摘The host immune response effecting on biomaterials is critical to determine implant fates and bone regeneration property.Bone marrow stem cells(BMSCs)derived exosomes(Exos)contain multiple biosignal molecules and have been demonstrated to exhibit immunomodulatory functions.Herein,we develop a BMSC-derived Exos-functionalized implant to accelerate bone integration by immunoregulation.BMSC-derived Exos were reversibly incorporated on tannic acid(TA)modified sulfonated polyetheretherketone(SPEEK)via the strong interaction of TA with biomacromolecules.The slowly released Exos from SPEEK can be phagocytosed by co-cultured cells,which could efficiently improve the biocompatibilities of SPEEK.In vitro results showed the Exos loaded SPEEK promoted macrophage M2 polarization via the NF-κB pathway to enhance BMSCs osteogenic differentiation.Further in vivo rat air-pouch model and rat femoral drilling model assessment of Exos loaded SPEEK revealed efficient macrophage M2 polarization,desirable new bone formation,and satisfactory osseointegration.Thus,BMSC-derived Exos-functionalized implant exerted osteoimmunomodulation effect to promote osteogenesis.Lei Fan Pengfei Guan Cairong Xiao Huiquan Wen Qiyou Wang Can Liu Yian Luo Limin Ma Guoxin Tan Peng Yu Lei Zhou Chengyun Ning 2021Bioactive Materials2021,6,9:11
5Promoting Bone Mesenchymal Stem Cells and Inhibiting Bacterial Adhesion of Acid-Etched Nanostructured Titanium by Ultraviolet Functionalization显示文摘Titanium(Ti) and its alloys are used extensively in orthopedic implants because of their excellent biocompatibility,mechanical properties and corrosion resistance. However,titanium-based implant materials face many severe complications,such as implant loosening due to poor osseointegration and bacterial infections,which may lead to implant failure. Hence,preparing a biomaterial surface,which enhances the interactions with host cells and inhibits bacterial adhesion,may be an optimal strategy to reduce the incidence of implant failure. This study aims to improve osseointegration and confer antibacterial properties on Ti through a combination of two surface modifications including nanostructuring generated by acid etching and ultraviolet(UV) light treatment.Our results showed that without UV treatment,the acid etching treatment of Ti surface was effective at both improving the adhesion of bone mesenchymal stem cells(BMSCs) and increasing bacterial adhesion. A further UV treatment of the acid-etched surface however,not only significantly improved the cell adhesion but also inhibited bacterial adhesion. The acid-etched nanostructured titanium with UV treatment also showed a significant enhancement on cell proliferation,alkaline phosphatase(ALP) activity and mineralization. These results suggest that such nanostructured materials with UV treatment can be expected to have a good potential in orthopedic applications.Guobo Lan Mei Li Ying Tan Lihua Li Xiaoming Yang Limin Ma Qingshui Yin Hong Xia Yu Zhang Guoxin Tan Chengyun Ning 2015Journal of Materials Science & Technology2015,31,2:7
6Choice behavior of commuters’rail transit mode during the COVID-19 pandemic based on logistic model显示文摘To understand whether commuters will take rail transit during the COVID-19 pandemic,a logistic regression model was constructed from three aspects of personal attributes,travel attributes and perception of COVID-19 based on 559 valid questionnaires.The results show that:occupation,commuting tools before the COVID-19 pandemic,walking time from residence to the nearest subway station,the possibility of being infected in private car and the possibility of being infected in public transport have significant influence on the commuters’choice of rail transit.Self-employed people and freelancers,commuters who used non-public transport before the COVID-19 pandemic,and commuters who take longer to walk from their residences to the nearest subway station are less likely to commute by rail transit during the COVID-19 pandemic.Commuters who think that the risk of being infected with the virus in public transport is higher have a lower probability of choosing rail transit.The confidence in bus/subway/taxi/taxi-hailing of commuters who do not choose to commute by rail transit during the COVID-19 pandemic is not high.The study of this paper can provide reference for the formulation of urban rail transit control measures during the COVID-19 pandemic,so as to formulate more perfect measures to ensure the safety of the returning workers.Limin Tan Changxi Ma 2021Journal of Traffic and Transportation Engineering(English Edition)2021,8,2:6
7Effects on Growth Performance and Feed Digestibility of Hainan Black Pigs by Adding Lysine in Low Protein Diet显示文摘[Objective] The paper was to study the effects on growth performance and feed digestibility of Hainan black pigs by adding lysine in low protein diet.[Method] A total of 36 Hainan black pigs with the body weight of(46.34 ±3.06) kg were randomly divided into three groups:control group(protein level 15%,lysine level 0.83%),experimental group I(protein level 13%,0.83%),and experimental group II(protein level 13%,lysine level 1.03),each group had three replicates of four pigs.The trial lasted 35 d.[Result] The growth performance of Hainan black pig in group II had no significant difference with that in control group(P>0.05).The apparent digestibility of crude protein and phosphorus of Hainan black pigs in Group II increased significantly(P<0.05),which were increased by 10.08% and 11.85% respectively compared to the control group;the apparent digestibility of calcium was increased,but the difference was not significant(P>0.05).[Conclusion] It will not reduce the growth performance of Hainan black pig when the protein level of diet is reduced by 2% and the lysine level is increased to 1.03%.It is recommended that the diet can be used in the production of Hainan black pig.Wei Limin Liu Quanwei Sun Ruiping Zheng Xinli Wang Feng Tan Shuyi Huang Lili Xing Manping 2018Animal Husbandry and Feed Science2018,10,2:4
8Self-organized phase-transition lithography for all-inorganic photonic textures显示文摘Realizing general processing applicable to various materials by one basic tool has long been considered a distant dream.Fortunately,ultrafast laser-matter interaction has emerged as a highly universal platform with unprecedented optical phenomena and provided implementation paths for advanced manufacturing with novel functionalities.Here,we report the establishment of a three-dimensional(3D)focal-area interference field actively induced by a single ultrafast laser in transparent dielectrics.Relying on this,we demonstrate a radically new approach of self-organized phase-transition lithography(SOPTL)to achieve super-resolution construction of embedded all-inorganic photonic textures with extremely high efficiency.The generated textures exhibit a tunable photonic bandgap(PBG)in a wide range from〜1.3 to〜2 pm.More complicated interlaced textures with adjustable structural features can be fabricated within a few seconds,which is not attainable with any other conventional techniques.Evidenee suggests that the SOPTL is extendable to more than one material system.This study augments light-matter interaction physics,offers a promising approach for constructing robust photonic devices,and opens up a new research direction in advaneed lithography.Bo Zhang Dezhi Tan Zhuo Wang Xiaofeng Liu Beibei Xu Min Gu Limin Tong Jianrong Qiu 2021Light(Science & Applications)2021,10,6:3
9Low-cost hybrid integrated 4 × 25 GBaud PAM-4CWDM ROSA with a PLC-based arrayed waveguide grating de-multiplexer显示文摘We demonstrate a low-cost hybrid integrated and compact 100 GBaud four-lane coarse wavelength division multiplexing (CWDM) receiver optical sub-assembly (ROSA) based on an arrayed waveguide grating de-multiplexer in the O band. To achieve the horizontal light coupling between the planar light-wave circuit (PLC) based arrayed waveguide grating de-multiplexer and photodetector array, a 42°polished facet is applied for total reflection.A flexible printed circuit with high-frequency coplanar waveguides is used for a power supply of trans-impedance amplifier and signal transmission.The fabricated CWDM ROSA module, whose size is 18mm×22mm×6mm, shows a 3 dB bandwidth of 21.2,18.4,19.6,and 19.3 GHz,respectively,in each lane. The overall symbol error rates are at a magnitude of 10^-7 for 25 GBaud four-level pulse amplitude modulation (PAM-4) transmission with an average input optical power of 5dBm.Lei Liu Limin Chang Yingxin Kuang Zezheng Li Yang Liu Huan Guan Manqing Tan Yude Yu Zhiyong Li 2019Photonics Research2019,7,7:3
10In-depth Understanding of the Effects of Intramolecular Charge Transfer on Carbon Nitride Based Photocatalysts显示文摘Intramolecular charge transfer(ICT)derived from a donor-acceptor system has been applied for years to enhance the charge mobility in the field of organic photovoltaics and chemical sensing.Similar strategies have gradually been developed in polymeric graphitic carbon nitride(GCN)photocatalytic systems for promoting the light absorption and charge separation.However,there are no reviews focusing on the effects of ICT after the modification of GCN so far.Herein,we summarize some typical literature on GCN engineering to expound profoundly the roles of ICT in electronic properties regulation in terms of in-situ formation and molecular coupling.At last,some important perspectives are also proposed.This review will deepen understanding of the traditional theory for a new recognition among such many methods to improve the performance of GCN.Zongzhao Sun Yueyang Tan Jianyong Wan Limin Huang 2021Chinese Journal of Chemistry2021,39,7:2
11Coalfield structure and structural controls on coal in China显示文摘The occurrence of coal-bearing strata in a variety of coal-bearing basins of China is characterized by late tectonic deformation and remarkable spatial and geochronologic differences.The main controlling factors,which determine the tectonic framework of coalfields,include the geodynamic environment,tectonic evolution,deep structures,tectonic stress,and lithologic combination of the coal measures.The Chinese continent has experienced multi-stage tectonic movements since the Late Paleozoic.The spatial and temporal heterogeneity of its continental tectonic evolution,the complexity of its basement properties,and its stratigraphic configurations control the tectonic framework of its coalfields’present complex and orderly patterns.The concept of coal occurrence structural units is proposed in this paper and is defined as the structural zoning of coal occurrence.China’s coalfields are divided into five coal occurrence structural areas,and the structural characteristics of the coalfields in five main coal occurrence areas throughout the country are summarized.Based on the analysis of the relationship between the structure characteristics and occurrence of coal in these coalfields,the coal-controlling structures are divided into six groups:extensional structural styles,compressional structural styles,shearing and rotational structural styles,inverted structural styles,sliding structural styles,and syn-depositional structural styles.In addition,the distribution of coal-controlling structural styles is briefly summarized in this paper.Daiyong Cao Anmin Wang Shuzheng Ning Huantong Li Aijun Guo Limin Chen Kang Liu Jieqing Tan Zhihong Zheng 2020International Journal of Coal Science & Technology2020,7,2:2

Goats were fed with Juncao+concentrate(control group), pel-leted total mixed ration I(particle size 6 mm, experimental group I) and II(particle size 5 mm, experimental group II), respectively. The trial lasted 45 d.[Result](1) The final weight and daily gain of experimental group II were significantly higher than those of control group( P<0.05), and the daily gain of experimental group II was also higher than that of experimental group I(P<0.05);the feed intake of experimental group II was markedly higher than that of control group(P<0.05), but was significantly lower than that of experimental group I(P<0.05). The feed/gain ratio of experimental group II was significantly lower than those of control group and experimental group I(P<0.05).(2) The feed gain cost of experimental group II was markedly lower than that of control group(P<0.05), but the gross profit was significantly higher than those of control group and experimental group I(P<0.05).(3) Compared with the control group, the serum total protein content of experimental group II increased markedly( P<0.05) while the urea nitrogen level decreased(P>0.05).[Conclusion] The pelleted total mixed ration with the particle size of 5 mm obtained better fattening ef-fect, and obviously improved the serum total protein level.Liu Quanwei Wei Limin Wang Feng Tan Shuyi Sun Ruiping Huang Lili Zheng Xinli 2019Animal Husbandry and Feed Science2019,11,1:2
13Multiferroic and magnetoelectric properties of La_(0.1)Ba_(0.9)Fe_(12)O_(19) ceramics显示文摘La0.1Ba0.9Fe12O19 powders with similar hexagonal crystal structure to Ba Fe12O19 have been successfully synthesized using polymer precursor method. The powders were suppressed into pellets, which were sintered into ceramics at 1,300 °C for 1 h. The structure and morphology of the ceramics have been determined by X-ray diffraction(XRD) and field emission scanning electron microscopy(FESEM). Clear electric hysteresis loops upon different amplitude of external fields indicates that La0.1Ba0.9Fe12O19 is a kind of possible ferroelectric compound. The maximum remnant polarization of La0.1Ba0.9Fe12O19 ceramic is estimated to be *9.6 l C/cm2. The Fe O6 octahedron in its perovskite-like hexagonal unit cell as well as the shift of Fe3?off the center of octahedron are proposed to be the origin of electric polarization in La0.1Ba0.9Fe12O19. Simultaneous occurrence of large ferroelectricity and strong ferromagnetism has been observed in La0.1Ba0.9Fe12O19 ceramics. More interestingly, this compound demonstrates electronic polarization behavior being actuated by an applied magnetic field, indicating the existence of magnetoelectric(ME) coupling effect in the La0.1Ba0.9Fe12O19 ceramics. Our results may lead to new device applications such as magnetically recorded ferroelectric memory.Guolong Tan Wenrong Wang Wei Li Limin Liu 2014Chinese Science Bulletin2014,59,36:1

17The First High-quality Reference Genome of Sika Deer Provides Insights into High-tannin Adaptation显示文摘Sika deer are known to prefer oak leaves,which are rich in tannins and toxic to most mammals;however,the genetic mechanisms underlying their unique ability to adapt to living in the jungle are still unclear.In identifying the mechanism responsible for the tolerance of a highly toxic diet,we have made a major advancement by explaining the genome of sika deer.We generated the first high-quality,chromosome-level genome assembly of sika deer and measured the correlation between tannin intake and RNA expression in 15 tissues through 180 experiments.Comparative genome analyses showed that the UGT and CYP gene families are functionally involved in the adaptation of sika deer to high-tannin food,especially the expansion of the UGT family 2 subfamily B of UGT genes.The first chromosome-level assembly and genetic characterization of the tolerance to a highly toxic diet suggest that the sika deer genome may serve as an essential resource for understanding evolutionary events and tannin adaptation.Our study provides a paradigm of comparative expressive genomics that can be applied to the study of unique biological features in non-model animals.Xiumei Xing Cheng Ai Tianjiao Wang Yang Li Huitao Liu Pengfei Hu Guiwu Wang Huamiao Liu Hongliang Wang Ranran Zhang Junjun Zheng Xiaobo Wang Lei Wang Yuxiao Chang Qian Qian Jinghua Yu Lixin Tang Shigang Wu Xiujuan Shao Alun Li Peng Cui Wei Zhan Sheng Zhao Zhichao Wu Xiqun Shao Yimeng Dong Min Rong Yihong Tan Xuezhe Cui Shuzhuo Chang Xingchao Song Tongao Yang Limin Sun Yan Ju Pei Zhao Huanhuan Fan Ying Liu Xinhui Wang Wanyun Yang Min Yang Tao Wei Shanshan Song Jiaping Xu Zhigang Yue Qiqi Liang Chunyi Li Jue Ruan Fuhe Yang 2023Genomics, Proteomics & Bioinformatics2023,21,1:1
18Self-curling electroconductive nerve dressing for enhancing peripheral nerve regeneration in diabetic rats显示文摘Conductive scaffolds have been shown to exert a therapeutic effect on patients suffering from peripheral nerve injuries(PNIs).However,conventional conductive conduits are made of rigid structures and have limited applications for impaired diabetic patients due to their mechanical mismatch with neural tissues and poor plasticity.We propose the development of biocompatible electroconductive hydrogels(ECHs)that are identical to a surgical dressing in this study.Based on excellent adhesive and self-healing properties,the thin film-like dressing can be easily attached to the injured nerve fibers,automatically warps a tubular structure without requiring any invasive techniques.The ECH offers an intimate and stable electrical bridge coupling with the electrogenic nerve tissues.The in vitro experiments indicated that the ECH promoted the migration and adhesion of the Schwann cells.Furthermore,the ECH facilitated axonal regeneration and remyelination in vitro and in vivo through the MEK/ERK pathway,thus preventing muscle denervation atrophy while retaining functional recovery.The results of this study are likely to facilitate the development of non-invasive treatment techniques for PNIs in diabetic patients utilizing electroconductive hydrogels.Can Liu Lei Fan Zhenming Tian Huiquan Wen Lei Zhou Pengfei Guan Yian Luo Chuncheung Chan Guoxin Tan Chengyun Ning Limin Rong Bin Liu 2021Bioactive Materials2021,6,11:1
