| 1 | Effects of sludge dredging on the prevention and control of algae-caused black bloom in Taihu Lake,China显示文摘Algae-caused black bloom (also known as black water agglomerate) has recently become a critical problem in some Chinese lakes.It has been suggested that the occurrence of algae-caused black bloom was caused by the cooperation of nutrient-rich sediment with dead algae,and sludge dredging was adopted to control black bloom in some lakes of China.In this article,based on the simulation of black bloom using a Y-shape apparatus for modeling natural conditions,both un-dredged and dredged sites in three areas of Taihu Lake,China were studied to estimate the effects of dredging on the prevention and control of black bloom.During the experiment,drained algae were added to all six sites as an additional organic load;subsequently,the dissolved oxygen decreased rapidly,dropping to 0 mg/L at the sediment-water interface.Black bloom did not occur in the dredged sites of Moon Bay and Nan Quan,whereas all three un-dredged sites at Fudu Port,Moon Bay and Nan Quan experienced black bloom.Black bloom also occurred at the dredged site of Fudu Port one day later than at the other sites,and the odor and color were lighter than at the other locations.The color and odor of the black water mainly result from the presence of sulfides such as metal sulfides and hydrogen sulfide,among other chemicals,under reductive conditions.The color and odor of the water,together with the high concentrations of nutrients,were mainly caused by the decomposition of the algae and the presence of nutrient-rich sediment.Overall,the removal of the nutrient-rich sediment by dredging can prevent the occurrence and control the degree of algae-caused black bloom in Taihu Lake. | Wei He Jingge Shang Xin Lu Chengxin Fan | 2013 | Journal of Environmental Sciences2013，25，3： | 30 |
| 2 | Sulfur-containing amino acid methionine as the precursor of volatile organic sulfur compounds in algea-induced black bloom显示文摘After the application of methionine, a progressive and significant increase occurred in five volatile organic sulfur compounds (VOSCs): methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS) and dimethyl tetrasulfide (DMTeS). Even in the untreated control without a methionine addition, methionine and its catabolites (VOSCs, mainly DMDS) were found in considerable amounts that were high enough to account for the water's offensive odor. However, blackening only occurred in two methionine-amended treatments. The VOSCs production was observed to precede black color development, and the reaching of a peak value for total VOSCs was often followed by water blackening. The presence of glucose stimulated the degradation of methionine while postponing the occurrence of the black color and inhibiting the production of VOSCs. In addition, DMDS was found to be the most abundant species produced after the addition of methionine alone, and DMTeS appeared to be the most important compound produced after the addition of methionine+glucose. These results suggest that methionine acted as an important precursor of the VOSCs in lakes suffering from algea-induced black bloom. The existence of glucose may change the transformation pathway of methionine into VOSCs to form larger molecular weight compounds, such as DMTS and DMTeS. | Xin Lu Chengxin Fan Wei He Jiancai Deng Hongbin Yin | 2013 | Journal of Environmental Sciences2013，25，1： | 27 |

| 4 | Effect of reforestation on annual water yield in a large watershed in northeast China显示文摘A simplified water balance model in conjunction with an evapotranspiration(ET) model and cumulative forest cover data were used to quantify the changes in annual water yield in response to reforestation in a large watershed, northeast China. Cumulative forest cover increased by 22 %, leading to a significant decrease in estimated annual water yield. Reforestation increased ET(P = 0.0144), resulting in a remarkable decrease(P = 0.0001) in estimated annual water yield according to the water balance model. Reforestation increased ET by33 mm and decreased annual water yield by 38 mm per decade. The effect of reforestation on annual water yield can be quantified using a simplified water balance model in a large watershed, although our reforestation area was small(about 20 %) in relation to the total watershed area. | Yuefeng Yao Tijiu Cai Cunyong Ju Chengxin He | 2015 | Journal of Forestry Research2015，26，3： | 2 |
| 5 | PITPNC1 promotes the thermogenesis of brown adipose tissue under acute cold exposure显示文摘Brown adipose tissue (BAT) plays an essential role in non-shivering thermogenesis. The phosphatidylinositol transfer protein, cytoplasmic 1 (PITPNC1) is identified as a lipid transporter that reciprocally transfers phospholipids between intracellular membrane structures. However, the physiological significance of PITPNC1 and its regulatory mechanism remain unclear. Here, we demonstrate that PITPNC1 is a key player in thermogenesis of BAT. While Pitpnc1^(−/−) mice do not differ with wildtype mice in body weight and insulin sensitivity on either chow or high-fat diet, they develop hypothermia when subjected to acute cold exposure at 4℃. The Pitpnc1^(−/−) brown adipocytes exhibit defective β-oxidation and abnormal thermogenesis-related metabolism pathways in mitochondria. The deficiency of lipid mobilization in Pitpnc1^(−/−) brown adipocytes might be the result of excessive accumulation of phosphatidylcholine and a reduction of phosphatidic acid. Our findings have uncovered significant roles of PITPNC1 in mitochondrial phospholipid homeostasis and BAT thermogenesis. | Guoqing Tang Chengxin Ma Liangkui Li Shaoyan Zhang Fengsheng Li Jin Wu Yesheng Yin Qing Zhu Yan Liang Ru Wang He Huang Tong-Jin Zhao Hongyuan Yang Peng Li Feng-Jung Chen | 2022 | Science China(Life Sciences)2022，65，11： | 2 |
| 6 | Influence of endogenous ciliary neurotrophic factor on neural differentiation of adult rat hippocampal progenitors显示文摘Ciliary neurotrophic factor is the only known neurotrophic factor that can promote differentiation of hippocampal neural progenitor cells to glial cells and neurons in adult rats.This process is similar to spontaneous differentiation.Therefore,ciliary neurotrophic factor may be involved in spontaneous differentiation of neural stem cells.To verify this hypothesis,the present study isolated neural progenitor cells from adult male rats and cultured them in vitro.Results showed that when neural progenitor cells were cultured in the absence of mitogen fibroblast growth factor-2 or epidermal growth factor,they underwent spontaneous differentiation into neurons and glial cells.Western blot and immunocytochemical staining showed that exogenous ciliary neurotrophic factor strongly induced adult hippocampal progenitor cells to differentiate into neurons and glial cells.Moreover,passage 4 adult hippocampal progenitor cells expressed high levels of endogenous ciliary neurotrophic factor,and a neutralizing antibody against ciliary neurotrophic factor prevented the spontaneous neuronal and glial differentiation of adult hippocampal progenitor cells.These results suggest that the spontaneous differentiation of adult hippocampal progenitor cells is mediated partially by endogenous ciliary neurotrophic factor. | Jun Ding Zhili He Juan Ruan Ying Liu Chengxin Gong Shenggang Sun Honghui Chen | 2013 | Neural Regeneration Research2013，8，4： | 2 |
| 7 | Compositional and structural engineering of inorganic nanowires toward advanced properties and applications显示文摘As natural one-dimensional confined electron transport channels and photonpropagation paths, nanowires (NWs) display unmatched properties and hugepotential for application in diverse fields. The ability to construct a nanoscalefunctional system would enable significant advances in the currently desiredminiaturized device integration. To date, the basic properties of all types ofnanowire crystals, including metallic NWs, as well as group IV-related, III-V/II-VI compounds, and metal oxide NWs, are well understood. Regarding futurework, compositional (ie, doping and alloying) and structural (defect andheterostructure) designs to flexibly realize custom-made functionality areemphasized. Along this line, recent progress is reviewed, including the basicproperties (nanowire mechanics, electronics, and photonics) and applicationssuch as photodetectors and chemical/biological sensors. A review of the correlationsbetween the compositional/structural configuration of nanowires and thecorresponding functionality is also presented. The future development directionof this field is concluded and highlighted at the end. | Yong Sun Bo Sun Jingbo He Chengxin Wang | 2019 | InfoMat2019，1，4： | 2 |
| 8 | Self-standing hollow porous Co/a-WO_(x)nanowire with maximum Mott-Schottky effect for boosting alkaline hydrogen evolution reaction显示文摘The sufficient utilization of Mott-Schottky effect for boosting alkaline hydrogen evolution reaction(HER)depends upon scale minimizing of interface components and exposure maximizing of Mott-Schottky interface.Here,a self-standing porous tubular Mott-Schottky electrocatalyst is constructed by a self-template etching strategy,where amorphous WO_(x)(a-WO_(x))nano-matrix connects Co nanoparticles.This novel“Janus”electrocatalyst maximizes the Mott-Schottky effect by not only providing a highly exposed micro interface,but also simultaneously accelerating the water dissociation and optimizing the hydrogen desorption process.Experimental findings and theoretical calculations reveal that Co/a-WO_(x)Mott-Schottky heterointerface triggers the electron redistribution and a build-in electric field,which can not only optimize the adsorption energy of the reaction intermediates,but also facilitate the charge transfer.Thus,Co/a-WO_(x)requires an overpotential of only 36.3 mV at 10 mA·cm^(−2)and shows a small Tafel slope of 53.9 mV·dec^(−1)as well as an excellent 200-h long-term stability.This work provides a novel design strategy for maximizing the Mott-Schottky effect on promoting alkaline HER. | Jianpo Chen Jianping Zheng Weidong He Haikuan Liang Yan Li Hao Cui Chengxin Wang | 2023 | Nano Research2023，16，4： | 1 |
| 9 | Plant-protein-enabled biodegradable triboelectric nanogenerator for sustainable agriculture显示文摘As the use of triboelectric nanogenerators(TENGs)increases,the generation of related electronic waste has been a major challenge.Therefore,the development of environmentally friendly,biodegradable,and low-cost TENGs must be prioritized.Having discovered that plant proteins,by-products of grain processing,possess excellent triboelectric properties,we explore these properties by evaluating the protein structure.The proteins are recycled to fabricate triboelectric layers,and the triboelectric series according to electrical properties is determined for the first time.Using a special structure design,we construct a plant-protein-enabled biodegradable TENG by integrating a polylactic acid film,which is used as a new type of mulch film to construct a growth-promoting system that generates space electric fields for agriculture.Thus,from the plant protein to the crop,a sustainable recycling loop is implemented.Using bean seedlings as a model to confirm the feasibility of the mulch film,we further use it in the cultivation of greenhouse vegetables.Experimental results demonstrate the applicability of the proposed plant-protein-enabled biodegradable TENG in sustainable agriculture. | Chengmei Jiang Qi Zhang Chengxin He Chi Zhang Xiaohui Feng Xunjia Li Qiang Zhao Yibin Ying Jianfeng Ping | 2022 | Fundamental Research2022，2，6： | 1 |
| 10 | Multi-time scale photoelectric behavior in facile fabricated transparent and flexible silicon nanowires aerogel membrane显示文摘In recent years,transparent and flexible materials have been widely pursued in electronics and optoelectronics fields for usage as planar electrodes,energy conversion components and sensing units.As the most widely applied semiconductor material,the related progress in silicon is of great significance although with large difficulty.Herein,we report a one-step method to achieve flexible and transparent silicon nanowires aerogel membrane.A competitive carrier kinetics involving interfacial trapped carriers and the valence electrons transition is demonstrated,according to the photoelectric performance of a sandwiched graphene/silicon nanowires membrane/AI device,i.e.,rapidly positive photoresponse dominated by laser excited^ee-carriers generation(〜500 ms)and subsequent slow negative photocurrent evolution due to laser heating involved multi-levels process(>10 s).These results contribute to fabrication of silicon nanowire self-assembly structures and also the exploration of their optoelectrical properties in flexible and transparent devices. | Jin Yang Jingbo He Xiaobin Zou Bo Sun Yong Sun Chengxin Wang | 2022 | Nano Research2022，15，2： | 0 |
| 11 | Surface modification of CeO_(2-x) nanorods with Sn doping for enhanced nitrogen electroreduction显示文摘While the electrochemical nitrogen reduction reaction(NRR) represents a prospective blueprint for environmentally renewable ammonia generation,it has yet to overcome the limitations of weak activity and inferior selectivity.In this regard,surface modification tactic was constructed to markedly enhance the activity and selectivity via introducing Sn atoms into the surface of defective cerium oxide(denoted as Sn-CeO_(2-x)) as the active and robust electrocatalyst for NRR under benign environment.The introduction of Sn atoms in CeO_(2-x)can not only inhibit the HER activity of the catalyst but also modulate the electronic structure of ceria and optimize N-Ce interaction,thus enhancing NRR activity and selectivity.Outperforming all previous CeO_(2)-based NRR catalysts,this catalyst has demonstrated an ammonia yield rate of 41.1 μg mg_(cat)^(-1) h^(-1) and an exceptional Faradic efficiency of 35.3%.This work presents a viable approach for the development of advanced NRR electrocatalysts. | Yuhang Xiao Xiaohong Tan Yingying Guo Jianpo Chen Weidong He Hao Cui Chengxin Wang | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 12 | Preparation of Flexible Pt Counter Electrode on Indium-doped Tin Oxide Coated Polyethylene Naphthalate for Dye-sensitized Solar Cells显示文摘Flexible Pt counter electrode(CE)was prepared by a simple and fast electroless deposition on indium-doped tin oxide coated polyethylene naphthalate(ITO-PEN)plastic substrate for dye-sensitized solar cells(DSCs).The obtained Pt CE shows a high electrocatalytic activity for triiodide reduction and a low charge transfer resistance of 0.58Ω.cm 2.The assembled DSC exhibits an overall energy conversion efficiency of up to 4.53%,which is comparable to that of the DSC with sputtered Pt CE(4.74%).The present results indicate that the electroless deposition is an effective approach to prepare plastic Pt CEs as an alternative of the sputtering technology. | He Xuelong Liu Mei Yang Guanjun Fan Shengqiang Li Changjiu Li Chengxin | 2012 | 稀有金属材料与工程2012，41，S1： | 0 |
| 13 | Transparent ultrathin SiO_(2) nanowire aerogel displaying novel properties when interacting with water:A promising versatile functional platform显示文摘With low density,high porosity,and outstanding physicochemical stability,ceramic nanowire aerogels and sponges exhibit various interesting properties.Herein,an ultrathin silica nanowire aerogel(SiO_(2)NWsA)was achieved via a facile chemical vapor deposition route.In addition to good mechanical and thermal performances,properties resulting from active water-aerogel interactions are revealed,i.e.,outstanding transparency,strong capillary effect,enhanced compressive strength(a reversible strain of∼62%),switchable wettability and robust shape retention ability when filled with water.The physical mechanism related to these interesting properties is demonstrated basically according to its unique features(distinctly reduced nanowire diameter,enriched nanoscopic gap channels,and reinforced network).To demonstrate the superiority,an advantageous solar vapor generation system(hydrophilic NWs-A/reduced graphene oxide(rGO)/hydrophobic NWs-A)was obtained by integrating these favorable characteristics,giving rise to remarkably promoted vapor evaporation rate and energy efficiency compared to the rGO hydrophobic NWs-A device.These results contribute to the structural design and functional exploration of nanowire aerogels. | Jingbo He Churong Ma Jin Yang Xiaobin Zou Bo Sun Yong Sun Chengxin Wang | 2023 | Fundamental Research2023，3，1： | 0 |
| 14 | Self-supported metal(Fe, Co, Ni)-embedded nitrogen-doping carbon nanorod framework as trifunctional electrode for flexible Zn-air batteries and switchable water electrolysis显示文摘To meet the practical demand of wearable/portable electronics, developing high-efficiency and durable multifunctional catalyst and in-situ assembling catalysts into electrodes with flexible features are urgently needed but challenging. Herein, we report a simple route to fabricate bendable multifunctional electrodes by in-situ carbonization of metal ion absorbed polyaniline precursor. Alloy nanoparticles encapsulated in graphite layer are uniformly distributed in the N-doping carbon nanorod skeleton. Profiting from the favorable free-standing structure and the cooperative effect of metallic nanoparticles, graphitic layer and N doped-carbon architecture, the trifunctional electrodes exhibit prominent activities and stability toward HER, OER and ORR. Notably, due to the protection of carbon layer, the electrocatalysts show the reversible catalytic HER/OER properties. The overall water splitting device can continuously work for 12 h under frequent exchanges of cathode and anode. Importantly, the bendable metal air batteries fabricated by self-supported electrode not only displays the outstanding battery performance,achieving a decent peak power density(125 mW cm^(-2)) and exhibiting favorable charge-discharge durability of 22 h, but also holds superb flexible stability. Specially, a lightweight self-driven water splitting unit is demonstrated with stable hydrogen production. | Qiuyan Jin Liping Xiao Weidong He Hao Cui Chengxin Wang | 2023 | Green Energy & Environment2023，8，6： | 0 |
