1Physical effect of cloud seeding revealed by NOAA satellite imagery显示文摘From 0615 to 0749 UTC, 14 March 2000, a precipitation enhancement operation with AgI using an air- craft was conducted at the middle part of Shaanxi Province, China. 80 min after cloud seeding (0735 UTC), NOAA-14 satellite data showed a vivid zigzag cloud track on the satel- lite image. Its length is 301 km, and its average and maxi- mum width are 8.3 and 11 km. The cloud track is very simi- lar in shape with, but different in position and width from that of cloud seeding line. In order to determine that the cloud track is indeed caused by cloud seeding, a three-dimensional numerical model of transport and diffu- sion of seeding material is used to simulate the shape of seeding material concentration distribution, the turning points, width and length of seeding line. The simulated re- sults are compared with the features of cloud track at 0735 UTC. Every segment of the cloud track is consistent with the transport and diffusion of every segment of seeding line. The transport position, length, width and the variation trend of seeding line agree with those of cloud track. All suggest that the cloud track is the direct physical reflection of cloud seed- ing effect on the cloud top, which can respond to the trans- port and diffusion of seeding material. For this study case, the main effecting duration for every segment of seeding line is from 20 to 80 min, the time for each segment of seeding line diffusing to the maximum width is from about 50 to 70 min. This time is obtained from the appearing and disap- pearing time, width variation of the cloud track segments and simulated results. Also, the comparisons demonstrate that the numerical model of transport and diffusion can simulate the main characteristics of transport and diffusion of seeding material, and the simulating results are sound and trustworthy.YUXing DAIJin LEIHengchi XUXiaohong FANPeng CHENZhengqi DUANChanghui WANGYong 2005Chinese Science Bulletin2005,50,1:4

3Promoting nitric oxide electroreduction to ammonia over electron-rich Cu modulated by Ru doping显示文摘Electrocatalytic nitric oxide(NO)reduction is a promising strategy to produce ammonia.Developing a facile approach to synthesize efficient catalysts with enhanced NO electroreduction performance is highly desirable.Here,a series of Ru-doped Cu materials are constructed through in situ electroreduction of corresponding metal hydroxides.The optimized Ru_(0.05)Cu_(0.95)exhibits superior electrocatalytic performance for ammonia synthesis by using NO/Ar(1/4,n/n)as the feedstocks(Faradaic efficiency:64.9%,yield rate:17.68μmol cm^(-2)h^(-1)),obviously outperforming Cu counterpart(Faradaic efficiency:33.0%,yield rate:5.73μmol cm^(-2)h^(-1)).Electrochemical in situ Fourier transform infrared(FTIR)spectroscopy and online differential electrochemical mass spectrometry(DEMS)are adopted to detect intermediates and unveil the possible reaction pathway.The downshift of the Cu d-band center induced by Ru doping facilitates the rate-limiting hydrogenation step and decreases the desorption energy of NH_(3),leading to high Faradaic efficiency and yield of ammonia.Jiangwei Shi Changhong Wang Rong Yang Fanpeng Chen Nannan Meng Yifu Yu Bin Zhang 2021Science China Chemistry2021,64,9:2
4Stabilizing Co_(3)0_(4)nanorods/N-doped graphene as advanced anode for lithium-ion batteries显示文摘Tricobalt tetroxide(Co_(3)O_(4))is one of the promising anodes for lithium-ion batteries(LIBs)due to its high theoretical capacity.However,the poor electrical conductivity and the rapid capacity decay hamper its practical application.In this work,we design and fabricate a hierarchical Co_(3)O_(4)nanorods/N-doped graphene(Co_(3)0_(4)/NG)material by a facile hydrothermal method.The nitrogen-doped graphene layers could buffer the volume change of Co_(3)0_(4)nanorods during the delithium/lithium process,increase the electrical conductivity,and profit the diffusion of ions.As an anode,the Co_(3)O_(4)/NG material reveals high specific capacities of 1873.8 mA h g^(-1)after 120 cycles at 0.1 A·g^(-1)as well as 1299.5 mA·h·g^(-1)after 400 cycles at 0.5 A·g^(-1).Such superior electrochemical performances indicate that this work may provide an effective method for the design and synthesis of other metal oxide/N-doped graphene electrode materials.Yishan WANG Xueqian ZHANG Fanpeng MENC Cuangwu WEN 2021Frontiers of Materials Science2021,15,2:1
5Phosphate imbalance conducting by BPs-based cancer-targeting phosphate anions carrier induces necrosis显示文摘As a vital nutrient closely related to the cance r-cells proliferation,phosphate anions have been paid great attention as a promising anticancer agent.Generally,the transport of phosphate anions depends on a protein transport system which is regulated by ion homeostasis regulations.Herein,we designed a reactive anionic nanocarrier based on black phosphorus nanosheets(BPs)and artesunate(ART),which could enter cells through endocytosis to generate phosphate anions,avoiding the regulation of cell homeostasis.The ionic nanocarrier was coated by polydopamine to defend BPs and ART and functionalized by folate(FA)and hyaluronic acid(HA)for targeting factor.With the anchoring groups FA/HA targeted the carrier into cells,polydopamine coating decomposed to expose ART for further generating reactive oxygen species(ROS)in cancer cell microenvironment,providing oxidation conditions.Next,ROS generated by ART makes BPs decompose to phosphate anions with effectively speed,giving rise to the destruction of ion homeostasis to induce necro sis and inhibit the proliferation for cancer cells.In consequence,this research provides novel idea and direction for the ionic carriers and tumor therapeutics.Chunmeng Ma Jinlong Zhang Yuan Zhang Chen Ma Minrui Ma Fanpeng Ran Xiaoyan Liu Haixia Zhang 2021Chinese Chemical Letters2021,32,4:1

7Wide pillar roadway retained in the deep high gas coal seam显示文摘According to the geological and mining conditions of deep high gas coal seam,this paper established the mechanical model of stope surrounding rock,and analyzed the stress distribution and deformation failure mechanism of working face and coal pillar.The research determined the arrangement mode that adjacent working faces retain wide pillar,and the reasonable support method of roadway that the combined support of roof and grouting combined together.The reasonable time of reinforced roadway was determined.Through analyzing the mechanical model of the ways of roadway supporting,this research drew the conclusions as follows:the combined support of roof and working slope improved the support strength and range of surrounding rock,optimized the support by adjusting the angle of anchor,and reached the support requirements by using cement grouting in working slope and chemical grout in roof.The technology was applied in 15104 working face of Baoan Mine,and obtained good results.Pan Liyou Feng Enhu Zhao Qingshou Chen Liqiang Kong Fanpeng 2012International Journal of Mining Science and Technology2012,22,6:1
8Uncovering the degradation mechanism induced by ion-diffusion kinetics in large-format lithium-ion pouch cells显示文摘Battery electrochemistry in an actual cell is a complicated behavior influenced by the current density,uniformity,and ion-diffusion distance,etc.The anisotropism of the lithiation/delithiation degree is usually inevitable,and even worse,due to a trend of big-size cell design,typically such as 4680 and blade cells,which accelerated a battery failure during repeat lithiation and delithiation of cathodes.Inspire by that,two big-size pouch cells with big sizes,herein,are selected to reveal the ion-diffusion dependency of the cathodes at different locations.Interestingly,we find that the LiCoO_(2) pouch cell exhibits ~5 A h loss after 120 charge-discharge cycles,but a 15 A h loss is verified in a LiNixMnyCO_(1-x)-yO_(2)(NCM) cell.Synchrotron-based imaging analysis indicates that higher ion-diffusion rates in the LiCoO_(2)than that in the LiNixMnyCO_(1-x)-yO_(2)is the determined factor for the anisotropic cathode fading,which is responsible for a severe mechanical issue of particle damage,such as cracks and even pulverization,in the cathode materials.Meanwhile,we verify the different locations at the near-tab and bottom of the electrode make it worse due to the ion-diffusion kinetics and temperature,inducing a spatially uneven electrochemistry in the big-size pouch cell.The findings give an in-depth insight into pouch cell failure and make a guideline for high-energy cell design and development.Shi Zhou Xiaohong Zhang Cong Chen Ming Chen Fanpeng Kong Yingjie Qiao Jiajun Wang 2023Journal of Energy Chemistry2023,,8:0
9Mechanistic insight into the controlled synthesis of metal phosphide catalysts from annealing of metal oxides with sodium hypophosphite显示文摘Understanding and manipulating synthetic progress for precisely controlling the components and defects of nanomaterials is an important and challenging task in materials synthesis and nanocatalysis.Metal phosphides(MPs)have been explored as cheap advanced materials in various catalytic fields.MP materials are usually synthesized through gas-solid phosphorization reaction in a trial-to-error manner,but their formation mechanism and the origin of controlled synthesis remain unclear.Here,we combine in situ thermogravimetrc analysis-mass spectrometry(TG-MS)and quasi-in situ X-ray powder diffraction(XRD)analysis to probe the transformation mechanism from metal oxides(MOs)to MPs during the phosphorization process mediated by hypophosphite.Temperature,time,and the amount of hypophosphite are revealed as the driven forces while oxophilicity and crystallinity as the impeded forces,simultaneously control the component and defect level of a series of MP(M=Ni,Co,W,Mo,and Nb).The as-obtained WO2.9/WP is proved to be an efficient Z-scheme photocatalyst for oxidative coupling of methane with the total C2+production and C2H4 selectivity in C2+products reaching 10.75 pmolg-1 and 98.25%.Our work provides a fundamental understanding of the phosphorization treatment and thereby guides a viable synthetic route to the controlled synthesis of MOx-δ,MP,MOx-δ/MP,and MP/M heterostructured materials.Fanpeng Chen Bohang Zhao Mengyao Sun Cuibo Liu Yanmei Shi Yifu Yu Bin Zhang 2022Nano Research2022,15,12:0
10Treatment of Microalgae in Ballast Water Using Hydroxyl Radical in Accordance with the D-2 Ballast Water Discharge Standard显示文摘The effect of hydroxyl radical(·OH) on microalgae in ballast water is experimentally investigated. An ?OH plasma generator, which has a thin plate discharge Ag electrode covered by two α-Al2 O3 dielectric layers, is built. The plasma generator is filled with O2 and gaseous H2 O and is powered by a homemade power supply. ?OH radicals are generated by a series of plasma reactions and then dissolved into ballast water to kill microalgae. The maximum density of the killed microalgae is about 11 000 cells per milliliter. At this density, the microalgae are not reactivated at the 48th hour and the 120th hour in the treated ballast waters, and the content of chlorophyll in these microalgae decreases by 100%. The water quality returns to a normal level after 120 hours without secondary pollution of aquatic organisms and environment. These results show that the requirements of the D-2 ballast water discharge standard defined by the International Maritime Organization(IMO) are satisfied with the proposed treatment, and that ·OH is an ideal substance for killing microalgae during ballast water replacement of ships.MENG Xiangying CHEN Cao BAI Mindong SUN Jian MENG Fanpeng 2014高电压技术2014,40,1:0
11Investigation of the Oscillations in a Flare-productive Active Region显示文摘We investigate the oscillations in active region(AR)NOAA 12891,which produces a C2.0 three-ribbon flare accompanying a jet on 2021 November 2.Using the data from the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory,the 5 minutes decayless kink oscillations of coronal loops were detected and they are independent of the solar flare.Based on the observed oscillations and seismological diagnostics,we estimate that the Alfvén speed and magnetic field in these coronal loops are around 466 kms^(-1) sand 7.6 G,respectively.Additionally,the flare-related jet shows its plasmoids with 1 minute periodicity same as the intensity fluctuation of nearby flare ribbon.The correlation between the intensity fluctuation of jet and that of flare ribbon indicates that their 1 minute oscillations should originate from the same reconnection process.Fanpeng Shi Zongjun Ning Dong Li 2022Research in Astronomy and Astrophysics2022,22,10:0
12A WO3-CuWO4 nanostructured heterojunction for enhanced n-butanol sensing performance显示文摘Herein,a WO3-CuWO4 nanostructured heteroj unction was prepared by a facile two-step hydrothermal method.It is composed of a WO3 square microplate and CuWO4 nanoparticles.Then,the gas sensing properties were investigated under optimal operating temperature(120℃).The WO3-CuWO4 heterostructure shows good sensing performance towards n-butanol,with a response value up to 9.4 to towards 30 ppm n-butanol,and the response value is about 3 times higher than that of pristine Wo3.Its detection limit for n-butanol is 0.1 ppm,which indicates a potential application in lower concentration detection.Moreover,the response time of Wo3-CuWO4 nanostructured hete rojunction and the pristine WO3 are 21 s and 240 s respectively,revealing that there is a faster gas sensing process in the heterostructure.A possible sensing mechanism was then proposed on the basis of experimental data and band structure analysis.The significant enhancement of WO3-CuWO4 heterostructure could be attributed to the formation of heterojunction,which brings electronic sensitization and electron transport pathway modulation.The work offered a kind of novel and cost-effective sensing materials,and inspired more novel devices based on nanostructured heterojunction mechanism.Fanpeng Duanmu Qian Liu Shuhui Zhong Huiming Ji 2020Chinese Chemical Letters2020,31,5:0
