| 1 | Chance-constrained Coordinated Optimization for Urban Electricity and Heat Networks显示文摘Urban electricity and heat networks(UEHN)consist of the coupling and interactions between electric power systems and district heating systems,in which the geographical and functional features of integrated energy systems are demonstrated.UEHN have been expected to provide an effective way to accommodate the intermittent and unpredictable renewable energy sources,in which the application of stochastic optimization approaches to UEHN analysis is highly desired.In this paper,we propose a chance-constrained coordinated optimization approach for UEHN considering the uncertainties in electricity loads,heat loads,and photovoltaic outputs,as well as the correlations between these uncertain sources.A solution strategy,which combines the Latin Hypercube Sampling Monte Carlo Simulation(LHSMCS)approach and a heuristic algorithm,is specifically designed to deal with the proposed chance-constrained coordinated optimization.Finally,test results on an UEHN comprised of a modified IEEE 33-bus system and a 32-node district heating system at Barry Island have verified the feasibility and effectiveness of the proposed framework. | Zhinong Wei Juan Sun Zhoujun Ma Guoqiang Sun Haixiang Zang Sheng Chen Side Zhang Kwok W.Cheung | 2018 | CSEE Journal of Power and Energy Systems2018，4，4： | 6 |
| 2 | Intelligent identification of two-dimensional nanostructures by machine-learning optical microscopy显示文摘Two-dimensional (2D)materials and their heterostructures,with wafer-scale synthesis methods and fascinating properties,have attracted significant interest and triggered revolutions in corresponding device applications.However,facile methods to realize accurate,intelligent,and large-area characterizations of these 2D nanostructures are still highly desired.Herein,we report the successful application of machine-learning strategy in the optical identification of 2D nanostructures.The machine-leaming optical identification (MOI)method endows optical microscopy with intelligent insight into the characteristic color information of 2D nanostructures in the optical photograph.The experimental results indicate that the MOI method enables accurate,intelligent,and large-area characterizations of graphene,molybdenum disulfide,and their heterostructures, including identifications of the thickness,existence of impurities,and even stacking order.With the convergence of artificial intelligence and nanoscience,this intelligent identification method can certainly promote fundamental research and wafer-scale device applications of 2D nanostructures. | Xiaoyang Lin Zhizhong Si Wenzhi Fu Jianlei Yang Side Guo Yuan Cao Jin Zhang Xinhe Wang Peng Liu Kaili Jiang Weisheng Zhao | 2018 | Nano Research2018，11，12： | 5 |
| 3 | The protection effect of β-CD on DNA damage induced by ultrafine TiO_2显示文摘Under the photocatalysis of 365 nm ultraviolet radiation,ultrafine TiO2 caused the oxidative damage of Teasy plasmid DNA. The damage was determined by gel-electrophoresis. Then,a different dose of β-CD was added to the reaction,and the damage was restrained. The rate of damage restraining reached 97% when the mass of β-CD was 4 times as that of TiO2. Through UV scan and IR spectroscopy,it was found that the Ti-O of ultrafine TiO2 was bound with -OH of β-CD cavum and the -OH on the surface of ultrafine TiO2 disappeared,so the formation of ?OH was controlled. The ultrafine TiO2 has been widely used,but it was determined to be carcinogenic by some research. The protection effect of β-CD to DNA in the molecular level takes a new look on the surface modification of nano particles to decrease the toxic effect. | ZHU RongRong,WANG ShiLong,SUN XiaoYu,ZHANG Rui & YAO SiDe School of Life Science and Technology,Tongji University,Shanghai 200092,China | 2007 | Science China Chemistry2007，50，2： | 5 |
| 4 | SDS-PAGE study on photooxidation damage of lysozyme induced by riboflavin显示文摘The photooxidation damage of lysozyme under 315-375 nm irradiation in the presence of riboflavin was studied by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE).Indica- tions showed that the mechanisms and products of oxidative damage were relative to the concentra- tion of riboflavin,the time of irradiation and the ambience.The type I process was examined in a nitrogen saturated solution,whereas both type I and type II were observed in an aerobic atmosphere and type II was the dominant process.The study also suggested that antioxidants,such as melatonin, can reduce the damage of lysozyme effectively. | ZHANG ZhaoXia ZHAO HongWei ZHU HongPing GE Min WANG WenFeng YAO SiDe LI WenXin | 2007 | Science China Chemistry2007，50，1： | 3 |
| 5 | Pulse radiolysis study on gatifloxacin——A fluoroquinolone antibiotic显示文摘The reactions between gatifloxacin(GFX) and various one-electron oxidants,such as ˙OH,N3˙,Br2˙ˉ,and SO4˙ˉ,have been studied by pulse radiolysis techniques.The GFX radical anion formed in the reaction of GFX with eaqˉ could either be protonated or deprotonated,and the absorption of GFX radical anion was located at 390 nm.The transient species produced by the reaction of GFX with ˙OH radical shows a broad band in the 380?600 nm region with a shoulder,while the oxidation by N3˙,SO4˙ˉ,and Br2˙ˉ results in an absorption band with λmax = 370 nm.At neutral condition(pH 7),the rate constants of GFX reacting with ˙OH,N3˙,Br2˙ˉ,SO4˙ˉ and eaqˉ are estimated to be 1.0 × 1010,3.1 × 109,2.8 × 109,3.0 × 109,and 1.8 × 1010 dm3 mol?1 s?1,respectively.From the pH dependence on the formation of electron adducts and on the rate constant of GFX with eaqˉ,the pKa of GFX radical anion is estimated to be 5.5 and 9.3. | LI HaiXia LIU YanCheng TANG RuiZhi ZHANG Peng FU HaiYing YAO SiDe WANG WenFeng | 2012 | Science China Chemistry2012，55，7： | 3 |
| 6 | Reliability evaluation on sense-switch p-channel flash显示文摘In this paper,the reliability of sense-switch p-channel flash is evaluated extensively.The endurance result indicates that the p-channel flash could be programmed and erased for more than 10000 cycles;the room temperature read stress shows negligible influence on the p-channel flash cell;high temperature data retention at 150℃ is extrapolated to be about 5 years and 53 years corresponding to 30% and 40% degradation in the drive current,respectively.Moreover,the electrical parameters of the p-channel flash at different operation temperature are found to be less affected.All the results above indicate that the sense-switch p-channel flash is suitable to be used as the configuration cell in flash-based FPGA. | Side Song Guozhu Liu Hailiang Zhang Lichao Chao Jinghe Wei Wei Zhao Genshen Hong Qi He | 2021 | Journal of Semiconductors2021，42，8： | 2 |
| 7 | Effects of pH and polarity on the excited states of norfloxacin and its 4′-N-acetyl derivative:a steady-state and time-resolved study显示文摘The properties of norfloxacin(NFX)and its 4?-N-acetyl derivative(ANFX)are investigated in different pH aqueous solutions and H2O-CH3CN mixed solutions,to determine the effects of pH and polarity on their ground and excited states.The triplet states of NFX and ANFX are affected more by pH than by polarity.The pH dependence of the NFX and ANFX triplet states is likely due to the different quantum yields of different protonated forms.Steady-state fluorescence,time-resolved fluorescence,and laser flash photolysis experiments at different pH values provide clear evidence of the involvement of different intramolecular charge-transfer pathways in the singlet states of NFX and ANFX.The different electron-donating capacities of 1-N,1?-N,and 4?-N under different conditions determine the major pathway. | ZHANG Peng LI HaiXia YAO SiDe WANG WenFeng | 2014 | Science China Chemistry2014，57，3： | 2 |
| 8 | Poly(PEGMA) magnetic nanogels:Preparation via photochemical method,characterization and application as drug carrier显示文摘One-pot synthesis of magnetic nanogels with excellent biocompatibility via the photochemical method is reported in this paper.Poly(PEGMA) modified superparamagnetic nanogels(poly(PEGMA) magnetic nanogels) were synthesized by in-situ polymerization using poly(ethylene glycol) methacrylate(PEGMA) as the monomer and N,N'-methylene-bis-(acrylamide)(MBA) as the cross-linking agent in magnetite aqueous suspension under UV irradiation.The surface functional groups and components of magnetic nanogels were analyzed by Fourier transform infrared spectroscopy(FTIR) and a thermogra-vimetric analyzer(TGA).The results indicated that the poly(PEGMA) magnetic nanogels were synthe-sized successfully by coating poly(PEGMA) on the Fe3O4 nanoparticles under UV irradiation,and the Fe3O4 nanoparticles content in this nanogels was above 50 wt%.The morphology,size,zeta-potential and magnetic property were also characterized.The magnetic nanogels had a nearly spherical shape and core-shell structure,the average size in aqueous system measured by photon correlation spec-troscopy(PCS) was 68.4 nm,which was much bigger than that in the dry state,the nanogels behaved superparamagnetically with saturated magnetization of 58.6 emu/g,and the zeta-potential was-16.3-_17.3 mV at physiological pH(6.8-7.4) which could help to maintain stability in blood.The preliminary application as drug carrier was made and the doxorubicin-loaded magnetic nanogels had an excellent property in slow-release.The experiment indicated that the magnetic nanogel was an ideal candidate carrier in target drug delivery systems and other biomedical application. | SUN HanWen ZHANG LianYing ZHU XinJun KONG ChunYan ZHANG CunLan YAO SiDe | 2009 | Science China Chemistry2009，52，1： | 2 |

| 14 | Photochemical properties of a new kind of anti-cancer drug: N-glycoside compound显示文摘Due to the nontoxicity and efficient anti-cancer activity, more and more attention has been paid to N-glycoside compounds. Laser photolysis of N-(α-D-glucopyranoside) salicyloyl hydrazine (NGSH) has been performed for the first time. The research results show that NGSH has high photosensitivity and is vulnerable to be photo-ionized via a monophotonic process with a quantum yield of 0.02, generating NGSH+· and hydrated electrons. Under the aerobic condition of cells, the hydrated electrons are very easy to combine with oxygen to generate 1O2 and O2-, both of which are powerful oxidants that can kill the cancer cells. In addition, NGSH+· can be changed into neutral radicals by deprotonation with a pKa value of 4.02 and its decay constant was determined to be 2.55×109dm3·mol-1·s-1. NGSH also can be oxidized by SO4-. with a rate constant of 1.76×109 dm3·mol-1.s-1, which further confirms the results of photoionization. All of these results suggest that this new N-glycoside compound might be useful for cancer treatment. | ZHAO Ping WANG Mei ZHANG ShuPing SHAO SiChang SUN XiaoYu YAO SiDe WANG ShiLong | 2008 | Science China Chemistry2008，51，9： | 1 |

| 20 | Studies on kinetics of reactions between phycobiliproteins and hydroxyl radicals by a pulse radiolytic technique显示文摘Scavenging of hydroxyl radical (·OH) by phycobiliproteins (C-phycocyanin, Allophyco- cyanin and R-phycoerythrin) was studied by competitive kinetics methods. Hydroxyl radicals were generated from pulse radiolysis of aqueous systems saturated with nitrous oxide (N2O). The experimental results indicated that the three types of phycobiliproteins are all strong scavengers of· OH, the rate constants are around (2.8-5.6)×109 L·2 mol1 · s 1. | ZHANG Suping YAO Side WANG Wenfeng XIE Jie ZHANG Jianping ZHAO Jingquan JIANG Lijin | 2000 | Chinese Science Bulletin2000，45，10： | 0 |
