| 1 | Emission characteristics of surface second-order metal grating distributed feedback semiconductor lasers显示文摘To obtain high-power semiconductor lasers with stable operation in a single longitudinal mode and improve the characteristics of the output beam,an end-emitting surface second-order metal grating distributed feedback(DFB) laser emitting at around 940 nm is fabricated.The characteristics of the uncoated devices with and without gratings are tested under room temperature continuous-wave conditions without any temperature-control device and compared.The devices with gratings achieve high powers of up to 385 mW/facet and a small lateral far-field angle of 2.7° at 1.5 A,have only 4.13 nm/A wavelength-shift,and 0.09 nm spectral linewidth at 600 mA,and operate in a stable longitudinal mode.Devices without gratings operate in multimode,with a larger lateral far-field angle(7.3°) and spectral linewidth(1.3 nm),although with higher output powers.Because of the integration of second-order metal gratings and their very high coupling capability,the output beam quality is improved greatly,the lasing wavelength is stable and varies slowly with changes in injection current,while the spectrum is narrowed dramatically,and the far-field angles are greatly reduced.This opens the way for the realization of watt-scale power broad-stripe(>100 μm) surface second-order metal grating end and surface-emitting DFB lasers and arrays with single frequency,single mode operation and high output beam quality. | SHI JunXiu QIN Li LIU Yun ZHANG Nan ZHANG Jian ZHANG LiSen JIA Peng NING YongQiang ZENG YuGang ZHANG JinLong WANG LiJun | 2012 | Chinese Science Bulletin2012,57,17: | 5 |
| 2 | A STUDY ON CELLULAR AUTOMATA BASED ON RELATIONAL DATABASES AND SPATIO-TE MPORAL SIMULATIONS OF CULTURE DIFFUSION显示文摘This paper presents a development o f the extended Cellular Automata9CA),based on relational databases(RDB),to model dynamic interactions amon g spatial objects.The integration o f Geographical Information System(GIS)and CA has the great advantage of simu lationg geographical processes.But standard CA has some restrictions i n cellular shape and neighbourhood and neighbour rules,which restrict the CA’ s ability to simulate complex,real world environ-ments.This paper discusses a cell’ s spatialrelationbasedonthe spatialobject’ s geometricalandmon -geometricalc haracter-istics,and extends the cell’ s neighbour definition,and considers that the cell’ s neighbour lies in the forms of not on ly spa-tial adjacency but also attribute co rrelation.This paper then puts forw ard that spatial relations between t wo different cells can be divided into three types,including spatial adjacency,neighbour hood and complicated separation.Ba sed on tradition-al ideas,it is impossible to settle CA’ s restrictions completely.RDB -based CA is an academic experiment,in which some fields ard desighed to describe the essential information needed to define and select a cell’ s neighbour.The culture innovation diffusion system has mul tiple forms of space diffusion and in herited characteristics that the RD B -based CA is capable of simulating more effectiv ely.Finally this paper details a successful case study on the diffusion o f fashion wear trends.Compared to the original CA,the RDB -based CA is a more natural and efficient representation of human k nowl-edge over space,and is an effective t ol in simulation complex systems that have multiple forms of spatial diff usion. | MICHAELGallagher NIUHui-en LUOPing DUQing-yun HESu-fang LISen | 2002 | Chinese Geographical Science2002,12,4: | 4 |
| 3 | Dual activated NIR-Ⅱ fluorescence and photoacoustic imaging-guided cancer chemo-radiotherapy using hybrid plasmonic-fluorescent assemblies显示文摘Multimodal imaging in the second near-infrared window(NIR-II)guided cancer therapy is a highly precise and efficient cancer theranostic strategy.However,it is still a challenge to develop activated NIR-II optical imaging and therapy agents.In this study,we develop a pH-responsive hybrid plasmonic-fluorescent vesicle by self-assembly of amphiphilic plasmonic nanogapped gold nanorod(AuNNR)and fluorescent down-conversion nanoparticles(DCNP)(AuNNR-DCNP Ve),showing remarkable and activated NIR-II fluorescence(FL)/NIR-II photoacoustic(PA)imaging performances.The hybrid vesicle also exhibited superior loading capacity of doxorubicin as a superior drug carrier and efficient radiosensitizer for X-ray-induced radiotherapy.Interestingly,the accumulated hybrid AuNNR-DCNP Ve in the tumor resulted in a recovery of NIR-II FL imaging signal and a variation in NIR-II PA imaging signal.Dual activated NIR-II PA and FL imaging of the hybrid vesicle could trace drug release and precisely guided cancer radiotherapy to ultimately reduce the side effects to healthy tissue. | Tao Chen Lichao Su Xiaoguang Ge Wenmin Zhang Qingqing Li Xuan Zhang Jiamin Ye Lisen Lin Jibin Song Huanghao Yang | 2020 | Nano Research2020,13,12: | 4 |
| 4 | Magnetic resonance imaging for non-invasive clinical evaluation of normal and regenerated cartilage显示文摘With the development of tissue engineering and regenerative medicine,it is much desired to establish bioimaging techniques to monitor the real-time regeneration efficacy in vivo in a non-invasive way.Herein,we tried magnetic resonance imaging(MRI)to evaluate knee cartilage regeneration after implanting a biomaterial scaffold seeded with chondrocytes,namely,matrix-induced autologous chondrocyte implantation(MACI).After summary of the T2 mapping and the T1-related delayed gadolinium-enhanced MRI imaging of cartilage(dGEMRIC)in vitro and in vivo in the literature,these two MRI techniques were tried clinically.In this study,18 patients were followed up for 1 year.It was found that there was a significant difference between the regeneration site and the neighboring normal site(control),and the difference gradually diminished with regeneration time up to 1 year according to both the quantitative T1 and T2 MRI methods.We further established the correlation between the quantitative evaluation of MRI and the clinical Lysholm scores for the first time.Hence,the MRI technique was confirmed to be a feasible semiquantitative yet non-invasive way to evaluate the in vivo regeneration of knee articular cartilage. | Xian Xu Jingming Gao Shuyun Liu Liang Chen Min Chen Xiaoye Yu Ning Ma Jun Zhang Xiaobin Chen Lisen Zhong Lin Yu Liming Xu Quanyi Guo Jiandong Ding | 2021 | Regenerative Biomaterials2021,8,5: | 2 |

| 10 | Highly selective NIR fluorescent probe for acetylcholinesterase and its application in pesticide residues detection显示文摘A series of near-infrared(NIR)fluorescent substrates(NDRO-1∼8)derived from fluorophore NDRH with different volumes of ester bond as the recognition group were designed and synthesized for the detection of acetylcholinesterase(AChE),among which NDRO-1 with the smallest acetate group displayed the highest activity toward AChE.The detection limit of NDRO-1 for sensing AChE was 0.32μg/mL,and K_(m )was 6.40μmol/L,indicating ultra-sensitivity and good affinity of NDRO-1 toward AChE.NDRO-1 was used to detect the inhibitory of four kinds of pesticides including methamidophos,dichlorvos,and the detection limit was lower than 50μg/L,which was further used in pesticide residues detection. | Shengui He Shufang Zhang Xin Zhao Xinyue Zhu Lisen Chen Jingnan Cui | 2022 | Chinese Chemical Letters2022,33,9: | 1 |
| 11 | Activatable nanoscale metal-organic framework for ratiometric photoacoustic imaging of hydrogen sulfide and orthotopic colorectal cancer in vivo显示文摘Nanoscale metal-organic frameworks(nano MOFs)have emerged as a promising biomedical nanoplatform because of their unique properties.However,the exploration of nano MOFs in photoacoustic(PA)imaging is still limited.Here,a novel hydrogen sulfide(H2 S)-activated nano copper-based MOF(Cu-MOF)was developed as a near-infrared(NIR)ratiometric PA probe for in vivo monitoring of endogenous H2 S level and orthotopic colorectal cancer imaging via in situ reaction of nano Cu-MOFs with endogenous H2 S that is closely associated with tumor growth and proliferation in colon cancer.The synthesized nano Cu-MOFs displayed excellent PA responsiveness towards tumor H2 S level with high selectivity and rapid kinetics.The result suggests the developed probe may provide a unique opportunity to investigate the malignant behaviors of H2 S-associated events in vivo. | Wenmin Zhang Jun Wang Lichao Su Hui Chen Lan Zhang Lisen Lin Xiaoyuan Chen Jibin Song Huanghao Yang | 2020 | Science China Chemistry2020,63,9: | 1 |
