| 3 | A feasible strategy for focal cerebral ischemiareperfusion injury: remote ischemic postconditioning显示文摘It is difficult to control the degree of ischemic postconditioning in the brain and other ischemia-sensitive organs.Remote ischemic postconditioning could protect some ischemia-sensitive organs through measures on terminal organs.In this study,a focal cerebral ischemia-reperfusion injury model was established using three cycles of remote ischemic postconditioning,each cycle consisted of 10-minute occlusion of the femoral artery and 10-minute opening.The results showed that,remote ischemic postconditioning significantly decreased the percentage of the infarct area and attenuated brain edema.In addition,inflammatory nuclear factor-κB expression was significantly lower,while anti-apoptotic Bcl-2 expression was significantly elevated in the cerebral cortex on the ischemic side.Our findings indicate that remote ischemic postconditioning attenuates focal cerebral ischemia/reperfusion injury,and that the neuroprotective mechanism is mediated by an anti-apoptotic effect and reduction of the inflammatory response. | Qiang Liu Shengnian Zhou Yaodong Wang Fang Qi Yuan Song Siwei Long | 2014 | Neural Regeneration Research2014，9，15： | 21 |
| 4 | Nuclear factor-kappaB activation on the reactive oxygen species in acute necrotizing pancreatitic rats显示文摘AIM: To investigate the potential role of nuclear factor kappa-B (NF-κB) activation on the reactive oxygen species in rat acute necrotizing pancreatitis (ANP) and to assess the effect of pyrrolidine dithiocarbamate (PDTC, an inhibitor of NF-κB).METHODS: Rat ANP model was established by retrograde injection of 5% sodium taurocholate into biliopancreatic duct. Rats were randomly assigned to three groups (10rats each): Control group, ANP group and PDTC group. At the 6th h of the model, the changes of the serum amylase,nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD) and pancreatic morphological damage were observed. The expressions of inducible nitric oxide (iNOS) were observed by SP immunohistochemistry. And the expressions of NF-κB p65 subunit mRNA were observed by hybridization in situ.RESULTS: Serum amylase and NO level decreased significantly in ANP group as compared with PDTC administrated group [(7 170.40±1 308.63) U/L vs(4 074.10±1 719.78) U/L,P<0.05], [(76.95±9.04) μmol/L vs (65.18±9.02) μmol/L,P<0.05] respectively. MDA in both ANP and PDTC group rose significantly over that in control group [(9.88±1.52)nmol/L, (8.60±1.41) nmol/L, vs (6.04±1.78) nmol/L,P<0.05], while there was no significant difference between them. SOD levels in both ANP and PDTC group underwent a significant decrease as compared with that in control [(3 214.59±297.74) NU/mL, (3 260.62±229.44) NU/mL,vs (3 977.80±309.09) NU/mL, P<0.05], but there was no significant difference between them. Though they were still higher than those in Control group, pancreas destruction was slighter in PDTC group, iNOS expression and NF-κB p65 subunit mRNA expression were lower in PDTC group as compared with ANP group.CONCLUSION: We conclude that correlation among NF-κB activation, serum amylase, reactive oxygen species level and tissue damage suggests a key role of NF-κB in the pathogenesis of ANP. Inhibition of NF-κB activation may reverse the pancreatic damage of rat ANP and the production of reactive oxygen species. | Jin Long Na Song Xi-Ping Liu Ke-Jian Guo Ren-Xuan Guo | 2005 | World Journal of Gastroenterology2005，11，27： | 18 |
| 5 | Recent advances in gel polymer electrolyte for high-performance lithium batteries显示文摘Lithium batteries (LBs) have become increasingly important energy storage systems in our daily life. However, their practical applications are still severely plagued by the safety issues from liquid electrolyte, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. Gel polymer electrolytes (GPEs) are being considered as an effective solution to replace currently available organic liquid electrolyte for building safer LBs. This review provides recent advancements in GPEs applied for high-performance LBs. On the one hand, from the environmental and economic point of view, the skeletons of GPEs changed from traditional polymer to renewable and degradable polymer. On the other hand, in addition to being as a component with good electrochemical and physical characterizations, the GPEs also need to provide some functions for addressing the concerns of lithium (Li) dendrites, unstable cathode electrolyte interface, dissolution and migration of transition metal ions,'shuttle effect' of polysulfides, and so on. Finally, to synchronously meet the challenges from the advanced cathode and Li metal anode, the bio-based GPEs with multi-functionality are proposed to develop high-energy/powerdensity batteries in the future. | Ming Zhu Jiaxin Wu Yue Wang Mingming Song Lei Long Sajid Hussain Siyal Xiaoping Yang Gang Sui | 2019 | Journal of Energy Chemistry2019，28，10： | 17 |

| 8 | Implementation and security analysis of practical quantum secure direct communication显示文摘Rapid development of supercomputers and the prospect of quantum computers are posing increasingly serious threats to the security of communication.Using the principles of quantum mechanics,quantum communication offers provable security of communication and is a promising solution to counter such threats.Quantum secure direct communication(QSDC)is one important branch of quantum communication.In contrast to other branches of quantum communication,it transmits secret information directly.Recently,remarkable progress has been made in proof-of-principle experimental demonstrations of QSDC.However,it remains a technical feat to bring QSDC into a practical application.Here,we report the implementation of a practical quantum secure communication system.The security is analyzed in the Wyner wiretap channel theory.The system uses a coding scheme of concatenation of lowdensity parity-check(LDPC)codes and works in a regime with a realistic environment of high noise and high loss.The present system operates with a repetition rate of 1 MHz at a distance of 1.5 kilometers.The secure communication rate is 50 bps,sufficient to effectively send text messages and reasonably sized files of images and sounds. | Ruoyang Qi Zhen Sun Zaisheng Lin Penghao Niu Wentao Hao Liyuan Song Qin Huang Jiancun Gao Liuguo Yin Gui-Lu Long | 2019 | Light(Science & Applications)2019，8，1： | 15 |
| 9 | Radiofrequency ablation for hepatic hemangiomas: A consensus from a Chinese panel of experts显示文摘Recent studies have shown that radiofrequency(RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval. | Jun Gao Rui-Fang Fan Jia-Yin Yang Yan Cui Jian-Song Ji Kuan-Sheng Ma Xiao-Long Li Long Zhang Chong-Liang Xu Xin-Liang Kong Shan Ke Xue-Mei Ding Shao-Hong Wang Meng-Meng Yang Jin-Jin Song Bo Zhai Chun-Ming Nin Shi-Gang Guo Zong-Hai Xin Jun Lu Yong-Hong Dong Hua-Qiang Zhu Wen-Bing Sun | 2017 | World Journal of Gastroenterology2017，23，39： | 15 |
| 10 | Comparative studies on histological and ultra-structure of the pituitary of different ploidy level fishes显示文摘The histological and ultra-structure of the pituitary in diploid red crucian carp(Carassius auratus red var.),triploid crucian carp and allotetraploid hybrids within and after the breeding season were comparatively studied.The result showed that there were six endocrine cell types in the pituitary of these three kinds of fishes,and there was an obvious difference in cell size among different ploidy level fishes.As for the same type of pituitary cells,the cell size was increased gradually with the in- creasing ploidy level.In the breeding season,the allotetraploid hybrids had higher proportion of go- nadotropin cells(GTH)than triploids,and the triploids had higher proportion of GTH than diploids.The results were related to the earlier sexual maturity of allotetraploid hybrids and sterility of triploid cru- cian carp.On the other hand,among the three kinds of fishes,the proportion of somatotropin(STH) cells in triploids crucian carp was the highest,whereas that in allotetraploid hybrids was the lowest. The results might be connected with the faster growth rate of triploids and slower growth rate of al- lotetraploid hybrids.In addition,in GTH cells of meso-adenohypophysis after the breeding season, there were many endocrine particles in triploids,while those endocrine particles were released from the cells in allotetraploids and diploids.This result showed that the sterility of triploid crucian carp might be related to the hormone which was not released from the GTH cells.In a word,the present study indicated that the differences in the structure of pituitary among different ploidy level fishes contributed to their difference in the growth rate and gonadal development. | LONG Yu LIU Shaojun HUANG Weiren ZHANG Jian SUN Yuandong ZHANG Chun CHEN Song LIU Jinghui LIU Yun | 2006 | Science China(Life Sciences)2006，49，5： | 13 |
| 11 | Synergistic effect of oxymatrine and angiogenesis inhibitor NM-3 on modulating apoptosis in human gastric cancer cells显示文摘AIM: To investigate the synergistic effect of oxymatrine(OM) and angiogenesis inhibitor NM-3 on modulatingapoptosis in human gastric cancer cell lines SGC-7901,MKN-45, MKN-74. METHODS: Human gastric cancer lines SGC-7901,MKN-45, MKN-74 were treated with OM in the absenceand presence of NM-3. The inhibitory rates weredetected by MTT assay. Synergistic effect of OM andNM-3 on the growth of survivin, bcl-2, bax and p53 inSGC-7901 cells were examined by semiquantitative RT-PCR and Western blotting, and their growth inhibitoryeffects were also observed on SGC-7901 tumor xenograftin nude mice.RESULTS: OM combined with NM-3 exhibited asynergistic inhibitory effect on the growth of SGC-7901,MKN-45 and MKN-74 cells in a time-dependent manner.Twenty-four hours after treatment with OM, NM-3 aloneand their combination, mRNA expression of survivin andbcl-2 in SGC-7901 cells decreased, p53 mRNA expressionincreased. OM (4 g/L) combined with NM-3 significantlyincreased the expression of p53 mRNA and decreasedthe expression of survivin and bcl-2 compared witheither agent alone (193% ± 34% vs 129% ± 12%;44% ± 18% vs 92% ± 18%; 36 ± 17% vs 93% ± 23%,P < 0.05). Western blotting showed that the synergisticeffect of OM and NM-3 on protein translation of survivin,bcl-2 and p 53 was in accordance with their mRNAs.Furthermore, OM/NM-3 combination obviously exhibitedantitumor growth effect in xenografted human gastriccancer cells SGC-7901 compared with either agent alone.CONCLUSION: OM combined with NM-3 has synergisticinhibitory effects on human gastric cancer cells in vitro and can suppress the growth of xenografted human gastric cancer cells SGC-7901 in vivo. | Ming-Quan Song Jin-Shui Zhu Jin-Lian Chen Long Wang Wei Da Li Zhu Wei-Ping Zhang | 2007 | World Journal of Gastroenterology2007，13，12： | 13 |
| 12 | Applications of magnetic nanoparticles in surface-enhanced Raman scattering(SERS)detection of environmental pollutants显示文摘Environmental pollution, a major problem worldwide, poses considerable threat to human health and ecological environment. Efficient and reliable detection technologies, which focus on the appearance of emerging environmental and trace pollutants, are urgently needed. Surface-enhanced Raman scattering(SERS) has become an attractive analytical tool for sensing trace targets in environmental field because of its inherent molecular fingerprint specificity and high sensitivity. In this review, we focused on the recent developments in the integration of magnetic nanoparticles(MNPs) with SERS for facilitating sensitive detection of environmental pollutants. An overview and classification of different types of MNPs for SERS detection were initially provided, enabling us to categorize the huge amount of literature that was available in the interdisciplinary research field of MNPs based SERS technology. Then, the basic working principles and applications of MNPs in SERS detection were presented. Subsequently, the detection technologies integrating MNPs with SERS that eventually were used for the detection of various environmental pollutions were reviewed. Finally, the advantages of MNP-basedSERS detection technology for environmental pollutants were concluded, and the current challenges and future outlook of this technology in practical applications were highlighted. The application of the MNPsbasedSERS techniques for environmental analysis will be significantly advanced with the great progresses of the nanotechnologies, optics, and materials. | Dan Song Rong Yang Feng Long Anna Zhu | 2019 | Journal of Environmental Sciences2019，31，6： | 13 |
| 13 | Clinical characteristics and prognosis of community-acquired pneumonia in autoimmune disease-induced显示文摘BACKGROUND:Community-acquired pneumonia(CAP)in autoimmune diseases(AID)-induced immunocompromised host(ICH)had a high incidence and poor prognosis.However,only a few studies had determined the clinical characteristics of these patients.Our study was to explore the characteristics and predictors of mortality in CAP patients accompanied with AID-induced ICH.METHODS:From 2013 to 2018,a total of 94 CAP patients accompanied with AID-induced ICH,admitted to Emergency Department of Zhongshan Hospital,Fudan University,were enrolled in this study.Clinical data and the risk regression estimates of repeated predictors were evaluated by generalized estimating equations(GEEs)analysis.An open-cohort approach was used to classify patient's outcomes into the survival or non-survival group.RESULTS:The hospital mortality of patients with CAP occurring in AID-induced ICH was 60.64%.No significant differences were found with respect to clinical symptoms and lung images between survival and non-survival groups,while renal insufficiency and dysfunction of coagulation had higher proportions in non-survival patients(P<0.05).Both noninvasive ventilation(NIV)and invasive mechanical ventilation(IMV)were performed more frequently in non-survival group(P<0.05).By the multivariate GEEs analysis,the repeated measured longitudinal indices of neutrophilto-lymphocyte ratio(NLR)(odds ratio[OR]=1.055,95%confidence interval[95%CI]1.025–1.086),lactate dehydrogenase(LDH)(OR=1.004,95%CI 1.002–1.006)and serum creatinine(s Cr)(OR=1.018,95%CI 1.008–1.028),were associated with a higher risk of mortality.CONCLUSION:The CAP patients in AID-induced ICH had a high mortality.A significant relationship was demonstrated between the factors of NLR,LDH,s Cr and mortality risk in these patients. | Zhong-shu Kuang Yi-lin Yang Wei Wei Jian-li Wang Xiang-yu Long Ke-yong Li Chao-yang Tong Zhan Sun Zhen-ju Song | 2020 | World Journal of Emergency Medicine2020，11，3： | 12 |
| 14 | Identification of a Newly Isolated Getah Virus in the China-Laos Border,China显示文摘In this study, we isolated a virus strain(YN12031) from specimens of Armigeres subalbatus collected in the China-Laos border. BHK-21 cells infected with YN12031 exhibited an evident cytopathic effect(CPE) 32 h post-infection. The virus particles were spherical, 70 nm in diameter, and enveloped; they also featured surface fibers. Molecular genetic analysis revealed that YN12031 was closely related to alpha viruses such as Chikungunya virus and Sindbis virus, and located in the same clade as MM2021, the prototype of Getahvirus(GETV) isolated in Malaysia in 1955. Phylogenetic analysis of the E2 and capsid genes further revealed that YN12031 was located in the same clade as the Russian isolate LEIV/16275/Mag. Analysis of the homology of nucleotides and amino acids in the coding area and E2 gene demonstrated that the YN12031 isolated from the China-Laos border(tropical region) was related closest to the LEIV/16275/Mag isolate obtained in Russia(North frigid zone area) among other isolates studied. These results suggest that GETV can adapt to different geographical environments to propagate and evolve. Thus, strengthening the detection and monitoring of GETV and its related diseases is very crucial. | LI Yuan Yuan FU Shi Hong GUO Xiao Fang LEI Wen Wen LI Xiao Long SONG Jing Dong CAO Lei GAO Xiao Yan LYU Zhi HE Ying WANG Huan Yu REN Xiao Jie ZHOU Hong Ning WANG Gui Qin LIANG Guo Dong | 2017 | Biomedical and Environmental Sciences2017，30，3： | 12 |
| 15 | Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area. | Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG | 2018 | Science China Earth Sciences2018，61，11： | 12 |
| 16 | Effects of Nitrogen Fertilizer Level on Chlorophyll Fluorescence Characteristics in Flag Leaf of Super Hybrid Rice at Late Growth Stage显示文摘To compare the effects of slow-release nitrogen fertilizer at six different levels on the flag leaf chlorophyll fluorescence characteristics of super hybrid rice,a field fertilization experiment was conducted with super hybrid rice Y Liangyou 1 as a test material.The photosynthetic electron transport rate (ETR),effective quantum yield (EQY),photochemical quenching coefficient (q P),and non-photochemical quenching coefficient (NPQ) of flag leaves were measured at the initial heading,full heading,10 d after full heading and 20 d after full heading stages.Results showed that the values of ETR,EQY and q P increased with rice development from initial heading to 20 d after full heading,whereas the NPQ decreased.During the measured stages,ETR,EQY and q P increased initially and then decreased as nitrogen application amount increased,but they peaked at different nitrogen fertilizer levels.The maximum ETR and EQY values appeared at the treatment of 135 kg/hm 2 N.In conclusion,the optimum nitrogen amount for chlorophyll fluorescence characteristics of super hybrid rice was 135 180 kg/hm 2. | LONG Ji-rui MA Guo-hui WAN Yi-zheng SONG Chun-fang SUN Jian QIN Rui-jun | 2013 | Rice science2013，20，3： | 11 |

| 18 | Inheritance and molecular characterization of resistance to AHAS- inhibiting herbicides in rapeseed显示文摘Rapeseed is a very important oil crop in China;however,its production is challenging due to the absence of effective weed management strategies.This is predominantly because of a shortage of herbicide resistance genes.Acetohydroxyacid synthase(AHAS) herbicides inhibit AHAS,a key enzyme involved in branched-chain amino acid synthesis that is required for plant growth.A rapeseed line designated M342 with AHAS herbicide resistance was developed through seed mutagenesis and was studied to assess the level and mode of inheritance of the resistance and to identify the molecular basis of resistance.M342 possessed a high level of cross-resistance to sulfonylureas(SUs) and imidazolinones(IMIs).This resistance was due to AHAS insensitivity to these herbicides and was inherited as a dominant trait conferred by a single nuclear-encoded gene.Molecular analysis revealed the presence of a Trp574 Leu mutation in M342,and an allele-specific cleaved amplified polymorphic sequence(AS-CAPS) marker was developed and cosegregated with herbicide resistance in the F2,BC1,and BC2 populations.This mutation altered the transcript levels of Bn AHAS1 and Bn AHAS3 in M342 compared with those in the wild type,but it did not affect the agronomic or quality traits.The simple genetic inheritance of this mutation and the availability of the cleaved amplified polymorphic sequence(CAPS) marker and herbicide resistance gene should facilitate the development of herbicide-resistant rapeseed cultivars for effective weed control in China. | HU Mao-long PU Hui-ming GAO Jian-qin LONG Wei-hua CHEN Feng ZHOU Xiao-ying ZHANG Wei PENG Qi CHEN Song ZHANG Jie-fu | 2017 | Journal of Integrative Agriculture2017，16，11： | 11 |
| 19 | The effect of fire disturbance on short-term soil respiration in typical forest of Greater Xing'an Range, China显示文摘We investigated the effect of fire disturbance on short-term soil respiration in birch(Betula platyphylla Suk.) and larch(Larix gmelinii Rupr.) forests in Greater Xing'an range, northeastern China for further understanding of its effect on the carbon cycle in ecosystems. Our study show that post-fire soil respiration rates in B. platyphylla and L. gmelinii forests were reduced by 14% and 10%, respectively. In contrast, the soil heterotrophic respiration rates in the two types of forest were similar in post-fire and control plots. After fire, the contribution of root respiration to total soil respiration was dramatically reduced. Variation in soil respiration rates was explained by soil moisture(W) and soil temperature(T) at a depth of 5 cm. Exponential regression fitted T and W models explained Rs rates in B. platyphylla control and post-fire plots(83.1% and 86.2%) and L. gmelinii control and post-fire plots(83.7% and 88.7%). In addition, the short-term temperature coefficients in B.platyphylla control and post-fire plots were 5.33 and 5, respectively, and 9.12, and 5.26 in L. gmelinii control and post-fire plots, respectively. Our results provide an empirical baseline for studying the effect of fire disturbance on soil carbon balance and estimation of soil carbon flux in boreal forest. | Long Sun Tongxin Hu Ji Hong Kim Futao Guo Hong Song Xinshuang Lv Haiqing Hu | 2014 | Journal of Forestry Research2014，25，3： | 11 |
| 20 | Controlled TiO2 coating on hollow glass microspheres and their reflective thermal insulation properties显示文摘Hollow glass microspheres(HGMs)have great potential in building energy-saving and industrial insulation.Anatase TiO2-modified HGMs were prepared by a sol-gel method in acetic acid-ethanol solution.Scanning electron microscopy,X-ray diffraction,zeta-potential measurements,nitrogen-sorption measurements,and Fourier-transform infrared and ultraviolet-visible-near-infrared diffuse reflectance spectroscopies showed that the alkali modification of the HGMs greatly influenced the loading and microstructure of the TiO2 film.The TiO2 loading could be accurately controlled by ethanol addition and the TiO2 coating time.A mechanism for the TiO2 coating of the HGM surface is proposed.The synergistic action of hydrogen bonding and electrostatic forces resulted in close contact between the HGMs and TiO2 sol at pH 3.5.The effects of different TiO2 loading rates on the reflective and thermal insulation properties were studied.The near-infrared reflectance of 15.9%TiO2 coated on HGMs was 96.27%,and the inner surface temperature of the composite pigment coated on aluminum board was reduced by 22.4℃.The TiO2/HGM composite pigments exhibited excellent solar reflective and thermal insulation properties,so have potential in the construction of exterior walls and roofs. | Jie Long Chongwen Jiang Jundong Zhu Quzhi Song Jiang Hu | 2020 | Particuology2020，18，2： | 10 |
