| 1 | Effects of Substrate Temperature on the Properties of Mo-doped ZnO Films Prepared by RF Magnetron Sputtering显示文摘Transparent conducting molybdenum-doped zinc oxide (MZO) films were successfully prepared by radio frequency (RF) magnetron sputtering method on glass substrates under different substrate temperatures. The nature of MZO film is polycrystalline with hexagonal structure and a preferred orientation along c-axis. With increasing substrate temperature from room temperature to 400°C, the crystallinity of the films is deteriorated and the resistivity increases sharply due to both the decrease of carrier concentration and Hall mobility. The lowest resistivity achieved is 9.2×10-4Ω· cm with a high Hall mobility of 30 cm2·V-1·s-1 for the film deposited at room temperature. The average transmittance in the visible range exceeds 85% for all the samples. The optical band gap decreases from 3.30 to 3.25 eV with substrate temperature from room temperature to 400°C. | Xianwu Xiu Yuping Cao Zhiyong Pang Shenghao Han | 2009 | Journal of Materials Science & Technology2009，25，6： | 2 |

| 5 | Annealing Effect on Transport and Magnetic Properties of La_(0.67)Sr_(0.33)MnO_3 Thin Films Grown on Glass Substrates by RF Magnetron Sputtering显示文摘The manganite La0.67Sr0.33MnO3(LSMO) thin films were grown on glass substrates in a mixed argon and oxygen atmosphere by using RF magnetron sputtering.The structural characteristics,transport behaviors and magnetic properties of LSMO films were studied by annealing the films in air at 550 and 620 ℃.The out-of-plane lattice parameter a LSMO contracted after annealing and was close to that of bulk LSMO abulk,indicating that the internal strain was fully relaxed.Nanocrystalline grains were observed in the annealed films.Enhanced saturation magnetization and metal-to-insulator transition temperature(TMI=268 K) were also obtained.Curie temperatures(Tc) of the as-grown films was 340 K with the same as that of annealed at 550 ℃,but dropped to 315 K when the annealing temperature increased to 620 ℃,which can be attributed to the oxygen release during annealing in atmosphere. | Shaojie Fang Zhiyong Pang Fenggong Wang Liang Lin Shenghao Han | 2011 | Journal of Materials Science & Technology2011，27，3： | 1 |
| 6 | Immensely enhanced color-adjustable upconversion fluorescence in electron donor-acceptor exciplex chromophores doped with fluorescent emitters显示文摘Two-photon excited fluorescence materials usually suffer from inefficient two-photon absorption(TPA) and nonradiative excited states. Here, upconversion fluorescence in an electron donor-acceptor(DA) exciplex doped with fluorescent emitters are systematically investigated. It has been found that the undoped DA exciplex exhibits enhancements of ~129% and ~365% in upconversion fluorescence compared to donor-and acceptor-only systems, respectively. Interestingly, photoluminescence quantum yields(PLQYs) up to ~98.65% were measured and immensely enhanced upconversion fluorescence was observed after doping various fluorescent emitters into the DA exciplex. Our results reveal the existence of two-photon excited energy harvesting in a thermally activated delayed fluorescence(TADF) DA exciplex doped with fluorescent emitters, via reverse intersystem crossing followed by rapid F?rster resonance energy transfer. Moreover, the additional gain mechanism related to intermolecular CT interaction that occurs at the TPA stage is found in the TADF DA exciplex system. | ZHEN CHEN QIAN ZHOU HUITIAN DU YUAN YU CHUANG ZHANG SHENGHAO HAN ZHIYONG PANG | 2021 | Photonics Research2021，9，5： | 0 |

| 8 | Visual servoing-based pneumatic hair transplantation mechanism for robotic FUE surgery显示文摘Hair transplantation surgery is an effective solution for hair loss problems,among which follicle unit extraction(FUE)surgery is more widely used and favored.At present,most hair transplantation surgeries still rely heavily on manual operation by doctors and very few hair transplantation robots with complex structures have been introduced.This paper proposes a pneumatic hair transplantation mechanism for FUE surgery,equipped with a camera,capable of automatically performing both hair implantation and extraction with airflow.This pneumatic method eliminates the complex needle structure,has the function of temporarily storing the follicles inside the needle,thus facilitating the automation of transferring follicles from extraction to implantation.Then a visual feedback system is proposed to accurately position the follicles during the transplantation.The experimental results show that average distance deviation between the actual and target positions is 0.6128 mm and the average deviation of hair implantation depth is 1.7176 mm,which verify the feasibility of the proposed system. | Fulin Jia Shenghao Yang Chenxi Han Junye Li Xuanru Han Chao Zhang Jiaole Wang | 2023 | Biomimetic Intelligence & Robotics2023，3，4： | 0 |
| 9 | Cellular modulation by the mechanical cues from biomaterials for tissue engineering显示文摘Mechanical cues from the extracellular matrix(ECM)microenvironment are known to be significant in modulating the fate of stem cells to guide developmental processes and maintain bodily homeostasis.Tissue engineering has provided a promising approach to the repair or regeneration of damaged tissues.Scaffolds are fundamental in cell-based regenerative therapies.Developing artificial ECM that mimics the mechanical properties of native ECM would greatly help to guide cell functions and thus promote tissue regeneration.In this review,we introduce various mechanical cues provided by the ECM including elasticity,viscoelasticity,topography,and external stimuli,and their effects on cell behaviours.Meanwhile,we discuss the underlying principles and strategies to develop natural or synthetic biomaterials with different mechanical properties for cellular modulation,and explore the mechanism by which the mechanical cues from biomaterials regulate cell function toward tissue regeneration.We also discuss the challenges in multimodal mechanical modulation of cell behaviours and the interplay between mechanical cues and other microenvironmental factors. | Qiang Wei Shenghao Wang Feng Han Huan Wang Weidong Zhang Qifan Yu Changjiang Liu Luguang Ding Jiayuan Wang Lili Yu Caihong Zhu Bin Li | 2021 | Biomaterials Translational2021，2，4： | 0 |
