| 1 | Soil erosion and sediment interception by check dams in a watershed for an extreme rainstorm on the Loess Plateau,China显示文摘The magnitude of soil erosion and sediment load reduction efficiency of check dams under extreme rainstorms is a long-standing concern.The current paper aims to use check dams to deduce the amount of soil erosion under extreme rainstorms in a watershed and to identify the difference in sediment interception efficiency of different types of check dams.Based on the sediment deposition at 12 check dams with 100% sediment interception efficiency and sub-catchment clustering by taking 12 damcontrolled catchments as clustering criteria,the amount of soil erosion resulting from an extreme rainstorm event on July 26,2017(named '7·26' extreme rainstorm) was estimated in the Chabagou watershed in the hill and gully region of the Loess Plateau.The differences in the sediment interception efficiency among the check dams in the watershed were analyzed according to field observations at 17 check dams.The results show that the average erosion intensity under the '7-26' extreme rainstorm was approximately 2.03×10~4 t/km^2,which was 5 times that in the second largest erosive rainfall in 2017(4.15×10~3 t/km^2) and 11-384 times that for storms in 2018(0.53×10~2 t/km^2-1.81×10~3 t/km^2).Under the '7-26' extreme rainstorm,the amount of soil erosion in the Chabagou watershed above the Caoping hydrological station was 4.20 × 106 t.The sediment interception efficiency of the check dams with drainage canals(including the destroyed check dams) and with drainage culverts was 6.48 and 39.49%,respectively.The total actual sediment amount trapped by the check dams was 1.11 × 106 t,accounting for 26.36% of the total amount of soil erosion.In contrast,3.09×106 t of sediment were input to the downstream channel,and the sediment deposition in the channel was 2.23×10~6 t,accounting for 53.15%of the total amount of soil erosion.The amount of sediment transport at the hydrological station was8.60×10~5 t.The Sediment Delivery Ratio(SDR) under the '7·26' extreme rainstorm was 0.21.The results indicated that the amount of soil erosion was huge,and the sediment interception efficiency of the check dams was greatly reduced under extreme rainstorms.It is necessary to strengthen the management and construction technology standards of check dams to improve the sediment interception efficiency and flood safety in the watershed. | Leichao Bai Nan Wang Juying Jiao Yixian Chen Bingzhe Tang Haolin Wang Yulan Chen Xiqin Yan Zhijie Wang | 2020 | International Journal of Sediment Research2020，35，4： | 7 |
| 2 | NiPS_(3)quantum sheets modified nitrogen-doped mesoporous carbon with boosted bifunctional oxygen electrocatalytic performance显示文摘Electrocatalysts for oxygen reduction reactions(ORR)and oxygen evolution reactions(OER)are highly crucial and challenging toward the energy storage and conversion technologies such as fuel cells,metal-air batteries and water electrolysis.To replace noble-metal based catalysts and boost catalytic performance of carbon-based materials,we initially develop the nickel,phospho rus,sulfur and nitrogen co-modified mesoporous carbon(NiPS_(3)@NMC)as a bifunctional oxygen electrocatalyst.The perfo rmance for ORR(half-wave potential at 0.90 V)and OER(10 mA cm^(-2)at 1.48 V)surpasses those of Pt/C coupled with IrO_(2)catalysts and most of the non-precious metal based bifunctional electrocatalysts reported in related literature.Moreover,the electrochemical durability is also confirmed by accelerated durability tests(ADTs)and long-term chronoamperometry(CA)tests.We demonstrated that the interfacial effect between NiPS_(3)quantum sheets(QS s)and NMC substrates by thermal activation contributed to the enhanced oxygen electrode bifunctionality with more active sites,due to the electrons-donating from nickel,phosphorus and sulfur elements and relatively enriched pyridinic type N.Such excellent overall performance highlights the potential application of NiPS3 QSs and NMC composites as the materials on energy conversion and storage. | Kai Huang Yuyang Xu Yanpeng Song Ruyue Wanga Hehe Wei Yuanzheng Long Ming Lei Haolin Tang Jiangang Guo Hui Wu | 2021 | Journal of Materials Science & Technology2021，，6： | 7 |
| 3 | An efficient bifunctional electrocatalyst derived from layer-by-layer self-assembly of a three-dimensional porous Co-N-C@graphene显示文摘Three-dimensional (3D) porous carbon-based materials with tunable composition and microstructure are of great interest for the development of oxygen involved electrocatalytic reactions. Here, we report the synthesis of 3D porous carbon-based electrocatalyst by self-assembling Co-metal organic frameworks (MOF) building blocks on graphene via a layer-by-layer technique. Precise control of the structure and morphology is achieved by varying the MOF layer to tune the electrocatalytic properties. The as-produced electrocatalyst exhibits an excellent catalytic activity for the oxygen reduction reaction in 0.1molL^-1 KOH, showing a high onset potential of 0.963V vs. reversible hydrogen electrode (RHE) and a low tafel slope of 54mVdec^-1, compared to Pt/C (0.934V and 52mVdec^-1, respectively). Additionally, it shows a slightly lower potential vs. RHE (1.72V) than RuO2 (1.75V) at 10mAcm^-2 in an alkaline electrolyte. A rechargeable Zn-air battery based on the as-produced 3D porous catalyst demonstrates a high peak power density of 119mWcm^-2 at a cell voltage of 0.578V while retaining an excellent stability over 250 charge-discharge cycles. | Shichang Cai Rui Wang William M.

| 4 | Rational design of hierarchically porous Fe-N-doped carbon as efficient electrocatalyst for oxygen reduction reaction and Zn-air batteries显示文摘The rational design and construction of hierarchically porous nanostructure for oxygen reduction reaction (ORR) electrocatalysts is crucial to facilitate the exposure of accessible active sites and promote the mass/electron transfer under the gas-solid-liquid triple-phase condition. Herein, an ingenious method through the pyrolysis of creative polyvinylimidazole coordination with Zn/Fe salt precursors is developed to fabricate hierarchically porous Fe-N-doped carbon framework as efficient ORR electrocatalyst. The volatilization of Zn species combined with the nanoscale Kirkendall effect of Fe dopants during the pyrolysis build the hierarchical micro-, meso-, and macroporous nanostructure with a high specific surface area (1,586 m^(2)·g^(−1)), which provide sufficient exposed active sites and multiscale mass/charge transport channels. The optimized electrocatalyst exhibits superior ORR activity and robust stability in both alkaline and acidic electrolytes. The Zn-air battery fabricated by such attractive electrocatalyst as air cathode displays a higher peak power density than that of Pt/C-based Zn-air battery, suggesting the great potential of this electrocatalyst for Zn-air batteries. | Zihan Meng Neng Chen Shichang Cai Jiawei Wu Rui Wang Tian Tian Haolin Tang | 2021 | Nano Research2021，14，12： | 4 |
| 5 | Relationships Between Community Structure and Environmental Factors in Xixiakou Artificial Reef Area显示文摘The construction of artificial reefs has unparallelly developed for a few decades in China.Artificial reefs can be used to manage and conserve commercially exploited fish and crustacea.However,their suitability as ecological niche is poorly characterized.Therefore,in this study,we detected the seasonal variation of community biodiversity and the corresponding driving environmental factors.We also explored the relationships between dominant species and environmental factors to identify appropriate ecological niche areas.Different statistical analysis methods were used to assess species distribution within an artificial reef area in Xixiakou during nine sampling events in four seasons between 2017 and 2018.Non-metric multidimensional scaling(NMDS)and cluster analysis results indicated that the components of community can be divided into two clusters.Complexity of community,which is exhibited by species number,biodiversity,and catch per unit effort(CPUE),was significantly higher in summer than in other seasons.Generalized additive model(GAMs)results revealed the significant effects of temperature and chlorophyll a on the community structure.Sebastes schlegelii,Hexagrammos otakii,Conger myriaster and Charybdis japonica were the dominant species in four seasons.GAMs results indicated that temperature,dissolved oxygen(DO),pH and chlorophyll a affect the CPUE of dominant species significantly.The distinct suitable ecological niche for each dominant species was found in this study.For example,Charybdis japonica preferred to live in the area with 20.7–22.1℃,dissolved oxygen 7.07–7.15 mg L−1 and salinity 31.8–31.9.The results of this study are beneficial to resource conservation and fishery management. | YU Haolin YANG Wenzhao LIU Changdong TANG Yanli SONG Xiefa FANG Guangjie | 2020 | Journal of Ocean University of China2020，19，4： | 4 |

| 9 | Redox responsive nanoparticle encapsulating black phosphorus quantum dots for cancer theranostics显示文摘Effective cancer treatment puts high demands for cancer theranostics.For cancer diagnostics,optical coherence tomography(OCT)technology(including photothermal optical coherence tomography(PT-OCT))has been widely investigated since it induces changes in optical phase transitions in tissue through environmental changes(such as temperature change for PT-OCT).In this report,redox responsive nanoparticle encapsulating black phosphorus quantum dots was developed as a robust PT-OCT agent.Briefly,black phosphorus quantum dots(BPQDs)are incorporated into cysteine-based poly-(disulfide amide)(Cys-PDSA)to form stable and biodegradable nanoagent.The excellent photothermal feature allows BPQD/Cys-PDSA nanoparticles(NPs)as a novel contrast agent for high-resolution PT-OCT bioimaging.The Cys-PDSA can rapidly respond to glutathione and effectively release BPQDs and drugs in vitro and in vivo.And the obtained NPs exhibit excellent near-infrared(NIR)photothermal transduction efficiency and drug delivery capacity that can serve as novel therapeutic platform,with very low chemo drug dosage and side effects.Both of the polymer and BPQD are degradable,indicating this platform is a rare PT-OCT agent that is completely biodegradable.Overall,our research highlights a biodegradable and biocompatible black phosphorus-based nanoagent for both cancer diagnosis and therapy. | Haolin Chen Zhiming Liu Bo Wei Jun Huang Xinru You Jingyang Zhang Zhiling Yuan Zhilie Tang Zhouyi Guo Jun Wu | 2021 | Bioactive Materials2021，6，3： | 1 |

| 20 | Ionic Liquid Modified Inorganic Nanoparticles for Gaseous Phenol Adsorption显示文摘Ionic liquid modified silica nanoparticles were synthesized using a simple silane chemistry,followed by substitution reaction. The phenol adsorption performance was tested using temperature programmed desorption technique. The experimental results reveal that the introduction of ionic liquids on the surface of silica nanoparticles can improve the adsorption capacity of phenol compared to the pure silica nanoparticles.The initial adsorption capacity reaches 0.312 mmol·g^-1 at 25 ℃ under total pressure of 0.2 bar and it decreases slightly in the following adsorption-desorption cycles. The results demonstrate that introduction of ionic liquids can improve the phenol adsorption capacity and the simple material preparation process is feasible for industrial applications. | 宋旭艳 LI Dan 李冉 CHEN Yikun HUANG Long WEI Min PAN Xi ZHOU Hongshen TANG Haolin | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，4： | 1 |
