| 1 | NIR-II ?uorescence in vivo confocal microscopy with aggregation-induced emission dots显示文摘Significantly reduced tissue scattering of fluorescence signals in the second near-infrared(NIR-Ⅱ,1,000–1,700 nm)spectral region offers opportunities for large-depth in vivo bioimaging.Nowadays,most reported works concerning NIR-II fluorescence in vivo bioimaging are realized by wide-field illumination and 2D-arrayed detection(e.g.,via InGaAs camera),which has high temporal resolution but limited spatial resolution due to out-of-focus signals.Combining NIR-II fluorescence imaging with confocal microscopy is a good approach to achieve high-spatial resolution visualization of biosamples even at deep tissues.In this presented work,a NIR-II fluorescence confocal microscopic system was setup.By using a kind of aggregation-induced emission(AIE)dots as NIR-II fluorescent probes,800 lm-deep 3D in vivo cerebrovascular imaging of a mouse was obtained,and the spatial resolution at 700 lm depth could reach 8.78 lm.Moreover,the time-correlated single photon counting(TCSPC)technique and femtosecond laser excitation were introduced into NIR-II fluorescence confocal microscopy,and in vivo confocal NIR-II fluorescence lifetime microscopic imaging(FLIM)of mouse cerebral vasculature was successfully realized. | Wenbin Yu Bing Guo Hequn Zhang Jing Zhou Xiaoming Yu Liang Zhu Dingwei Xue Wen Liu Xianhe Sun Jun Qian | 2019 | Science Bulletin2019，64，6： | 10 |
| 2 | Syntheses, structures and magnetic properties of three Co(Ⅱ)coordination architectures based on a flexible multidentate carboxylate ligand and different N-donor ligands显示文摘Three new cobalt complexes,{[Co5(tci)2(bimb)3(3-O)2(H2O)2]·3DMF·4H2O}n(1),{[Co3(tci)2(bib)]·2DMF·2H2O}n(2)and{[Co(Htci)(bpea)0.5]·H2O}n(3)(H3tci=tris(2-carboxyethyl)isocyanurate,bimb=4,4′-bis(imidazol-1-yl)biphenyl,bib=1,4-bis(imidazol-1-yl)benzene,bpea=1,2-bis(4-pyridyl)ethane,DMF=N,N′-dimethylformamide),have been successfully synthesized through the assembly of Co(II)ions,H3tci and different N-donor ligands,respectively.All complexes were structurally characterized by single crystal X-ray diffraction,elemental analyses,IR spectra,thermogravimetric(TG)analyses and X-ray powder diffraction(XRPD).Complex 1 exhibits a 3D three-fold parallel interpenetrated 3D→3D structure with(65·8)CdSO4topology.Complex 2 is built from[Co3(2-Ocarboxyl)2(CO2)4]clusters and linear bib ligands,displaying a two-fold parallel interpenetrated(3,8)-connected(43)2(46·618·84)topology,while complex 3 is a 3D pillar-layered structure involving an infinite–Co–(2-Ocarboxyl)(CO2)–Co–chain.The diverse structures of the three complexes indicate that the skeletons of different N-donor ligands play an important role in the assembly of such different frameworks.In addition,magnetic investigation indicates that besides spin-orbit coupling of Co(II)ions,there exist antiferromagnetic exchange interactions in Co5and Co3clusters of 1 and 2,respectively. | TIAN Dan LIU SuiJun ZHANG DaShuai CHANG Ze HU TongLiang BU XianHe | 2013 | Science China Chemistry2013，56，12： | 5 |
| 3 | Abnormal interruption of water flow from an artesian well prior to 2008 Wenchuan earthquake显示文摘Water flow from an artesian well stopped on December 17,2007 but recovered when the Wenchuan Ms 8.0 earthquake occurred on May 12,2008.This well is located 90 km south of the epicenter in an extensional tectonic setting,where similar changes of water level and resistivity were observed at two other nearby sites.Our investigation suggests that this phenomenon was not caused by environmental disturbances,such as drought or borehole-drilling activity,but might be a precursor to the earthquake. | Liu Chenglong Che Yongtai Xu Yinju Shi Zheming Yang Xianhe | 2011 | Geodesy and Geodynamics2011，2，2： | 5 |

| 5 | N-polar InGaN nanowires: breaking the efficiency bottleneck of nano and micro LEDs显示文摘The efficiency of conventional quantum well light-emitting diodes(LEDs) decreases drastically with reducing areal size. Here we show that such a critical size scaling issue of LEDs can be addressed by utilizing N-polar In Ga N nanowires. We studied the epitaxy and performance characteristics of N-polar In Ga N nanowire LEDs grown on sapphire substrate by plasma-assisted molecular beam epitaxy. A maximum external quantum efficiency-11% was measured for LEDs with lateral dimensions as small as 750 nm directly on wafer without any packaging. The effect of electron overflow and Auger recombination on the device performance is also studied. This work provides a viable approach for achieving high-efficiency nano and micro LEDs that were not previously possible. | Xianhe Liu Yi Sun Yakshita Malhotra Ayush Pandey Ping Wang Yuanpeng Wu Kai Sun Zetian Mi | 2022 | Photonics Research2022，10，2： | 1 |
| 6 | Optimization of solvent swelling for efficient organic solar cells via sequential deposition显示文摘Compared to bulk heterojunction(BHJ)organic solar cells(OSCs)prepared by the blend casting in“one step process”,sequential deposition(SD)processed OSCs can realize an ideal profile of vertical component distribution due to the swelling of polymer films.Herein,we did trials on several kinds of second solvents for swelling the polymer layer,and investigated the packing structure and morphology of the swollen films and the performance of the resulting devices.We found that an optimized morphology can be achieved by solvent swelling while using orthodichlorobenzene(o-DCB)as the second layer processing-solvent,with polymer donor PffBT-3 as bottom layer,PC71BM as top layer and bicontinuous networks in the middle.Such solvent swelling process also makes the SD method exempt from thermal annealing treatment.The device based on SD yields a power conversion effi-ciency(PCE)up to 8.7%without any post-treatment,outperforming those from the devices based on SD using other solvents and that(7.06%)from BHJ device,respectively.We also extended the use of this approach to allpolymer blend system,and successfully improved the efficiency from 4.72%(chloroform)to 9.35%(o-DCB),which is among the highest PCEs in all-polymer-based OSCs fabricated with SD method.The results demonstrate that the swelling of the polymer by the second layer solvent is a necessity for SD,paving the way towards additivefree high-performance OSCs. | Qiaogan Liao Bangbang Li Huiliang Sun Chang Woo Koh Xianhe Zhang Bin Liu Han Young Woo Xugang Guo | 2021 | Materials Reports(Energy)2021，1，4： | 1 |
| 7 | Investigation for Natural Convection Heat Transfer of Sucrose Solution Using a Converging and Diverging Tube with Regularly——spaced Twisted Tapes显示文摘The natural convection heat transfer of a 60% sucrose solution in a vertical converging-diverging tube(CD) with regularly-spaced twisted tapes(RSTT) has been investigated numerically and experimentally. The effects of wall temperature and number of RSTT on the Nusselt number were studied in detail. The distributions of velocity and temperature in the 60% sucrose solution were studied and the simulated results of CD with RSTT were compared with those of the smooth tube. The influence of Rayleigh number and RSTT on the Nusselt number was conducted experimentally. The results indicate that the Nusselt number of the 60% sucrose solution obviously increased with the number of RSTT but increased inconspicuously with 2 and more twisted tapes. The simulation shows that the distance for achieving an optimal heat transfer performance is 46 times the diameter of the tube. The mechanism of the natural convection heat transfer enhancement of the 60% sucrose solution in relationship with the CD and the RSTT was analyzed, and the change of average tangential velocity with the axial distance was presented to demonstrate that the enhancement of heat transfer was realized mainly because of the increase in tangential velocity. | Zhang Lianshan Deng Xianhe Liu Weitao Yang Zhiping | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，1： | 1 |

| 11 | Syntheses, structures and magnetic properties of Fe_6 and Fe_(12) ferric wheels显示文摘Starting from the same Fe3O(RCO2)6 complex and using a similar synthesis strategy, the Fe6 and Fe12 wheels were obtained by utilizing two designed ligands, 2-amino-2-methyl-1,3-propanediol(L1) and 1,3-propanediol(L2), respectively. A biological buffer reagent, Bis-Tris(2-[bis-(2-hydroxyethyl)amino]-2-(hydroxymethyl)propane-1,3-diol) was first introduced in the synthesis of the Fe12 wheel, playing a vital role in adjusting the acidity of reaction environment. Magnetic studies on both Fe6 and Fe12 wheels revealed strong antiferromagnetic coupling between the spins on FeIII ions. | Guojian Ren Yanqing Liu Zhenxin Zhao Suijun Liu Songde Han Jian Xu Xianhe Bu | 2015 | Science China(Information Sciences)2015，58，12： | 0 |
| 12 | Progress in clinical research on the integration of Chinese and Western medicines for treating primary liver cancer显示文摘Primary liver cancer(PLC) is one of the most common malignant tumors in China. PLC is characterized by insidious onset, rapid progress, poor quality of life, and short survival time. Notably, current treatment strategies remain unsatisfactory. Traditional Chinese medicines(TCM) have been used to treat a variety of diseases, including liver diseases, for more than 2000 years. In this study, we performed a review of the use frequency and clinical efficacy of TCM in treating PLC. Relevant literature from January 1, 2009, to January 1, 2021 was retrieved from network databases of China National Knowledge Infrastructure(CNKI), Chongqing VIP, Wanfang, PubMed, and SinoMed. The most frequently used TCM and their efficacy in PLC treatment were summarized. Based on the inclusion and exclusion criteria, 33 articles were selected. Overall, the efficacy of the combination of TCM and Western medicines in the treatment of PLC was higher than that in the control groups(i.e. treatment with Western medicines alone)(65.11% vs.44.31%, P <.05). Among the 33 selected articles, 11 were investigated for TCM preparation(marketed drugs) and 22 for TCM formulas. In total, 102 types of TCM(single herbs) were used to treat PLC. The top five most frequently used TCM were Poria(14.71%), Astragali radix(13.73%), Atractylodis Macrocephalae Rhizoma(12.75%), Bupleuri radix(12.75%), and Glycyrrhizae radix et Rhizoma(11.76%). Of the 102 types of TCM, tonics were the most frequently used categories, followed by heat-clearing medicines, blood-invigorating medicines, and stasis-resolving medicines. Of 207 papers, 174(84.06%) could not be subjected to statistical analysis due to research quality. Further high-quality research on herb sources, formula components and dosage, toxicology, and ethics of TCM is necessary. In conclusion, TCM play a promising role in the treatment and management of PLC, although further investigations are warranted. | Kaiqi Liu Hongliang Li Jufeng Duan Xiaojing Chen Xiongjie Yu Xianhe Wang Ming Liu Bei Li Minglun Li Yibin Feng Xiaojun Cai Xuanbin Wang | 2021 | Journal of Traditional Chinese Medical Sciences2021，8，3： | 0 |
