| 1 | Biomechanism of impact resistance in the woodpecker's head and its application显示文摘The woodpecker does not suffer head/eye impact injuries while drumming on a tree trunk with high acceleration(more than 1000×g) and high frequency.The mechanism that protects the woodpecker's head has aroused the interest of ornithologists,biologists and scientists in the areas of mechanical engineering,material science and electronics engineering.This article reviews the literature on the biomechanisms and materials responsible for protecting the woodpecker from head impact injury and their applications in engineering and human protection. | WANG LiZhen LU Shan LIU XiaoYu NIU XuFeng WANG Chao NI YiKun ZHAO MeiYa FENG ChengLong ZHANG Ming FAN YuBo | 2013 | Science China(Life Sciences)2013，56，8： | 3 |
| 2 | Synthesis and ferroelectric properties of Nd doped multiferroic BiFeO_3 nanotubes显示文摘Nd doped multiferroic BiFeO3 (Bi0.94Nd0.06FeO3 (BNF)) nanotubes were successfully synthesized by a sol-gel template method.Electron microscopy investigations exhibited that these nanotubes had straight and smooth profile with diameters of about 200 nm and wall thickness of about 20 nm.A perovskite-type structure of BNF was confirmed in the nanotubes by high-resolution transmission electron microscopy and selected area electron diffraction analysis.These nanotubes had high resistivity.The dielectric constant and dielectric loss of the nanotubes were 126 and 0.040 at 1 MHz, respectively.The ferroelectric properties of these BNF nanotubes were demonstrated with a remnant polarization of 48 μC/cm2 and a coercive electric field of 163 kV/cm. | WANG Jing LI MeiYa LIU XiaoLian PEI Ling LIU Jun YU BenFang ZHAO XingZhong | 2010 | Chinese Science Bulletin2010，55，16： | 3 |

| 5 | Retrograde nerve growth factor signaling modulates tooth mechanical hyperalgesia induced by orthodontic tooth movement via acid-sensing ion channel 3显示文摘Orthodontic tooth movement elicits alveolar bone remodeling and orofacial pain that is manifested by tooth mechanical hyperalgesia.Nerve growth factor(NGF)is upregulated in periodontium and may modulate tooth mechanical hyperalgesia.The objectives were to examine the role of NGF in tooth mechanical hyperalgesia and to elucidate the underlying mechanisms.Tooth mechanical hyperalgesia was induced by ligating closed coil springs between incisors and molars in Sprague–Dawley rats.Retrograde labeling was performed by periodontal administration of fluor-conjugated NGF and the detection of fluorescence in trigeminal ganglia(TG).Lentivirus vectors carrying NGF shRNA were employed to knockdown the expression of NGF in TG.The administration of agonists,antagonists,and virus vectors into TG and periodontium was conducted.Tooth mechanical hyperalgesia was examined through the threshold of biting withdrawal.Our results revealed that tooth movement elicited tooth mechanical hyperalgesia that could be alleviated by NGF neutralizing antibody and that NGF was upregulated in periodontium(mainly in periodontal fibroblasts)and TG.Retrograde labeling revealed that periodontal NGF was retrogradely transported to TG after day 1.Acid-sensing ion channel 3(ASIC3)and NGF were co-expressed in trigeminal neurons and the percentage of co-expression was significantly higher following tooth movement.The administration of NGF and NGF neutralizing antibody into TG could upregulate and downregulate the expression of ASIC3 in TG,respectively.NGF aggravated tooth mechanical hyperalgesia that could be alleviated by ASIC3 antagonist(APETx2).Moreover,NGF neutralizing antibody mitigated tooth mechanical hyperalgesia that could be recapitulated by ASIC3 agonist(GMQ).NGF-based gene therapy abolished tooth mechanical hyperalgesia and downregulated ASIC3 expression.Taken together,in response to force stimuli,periodontal fibroblasts upregulated the expressions of NGF that was retrogradely transported to TG,where NGF elicited tooth mechanical hyperalgesia through upregulating ASIC3.NGF-based gene therapy is a viable method in alleviating tooth-movement-induced mechanical hyperalgesia. | Meiya Gao Xinyu Yan Yanzhu Lu Linghuan Ren Shizhen Zhang Xiaoqi Zhang Qianyun Kuang Lu Liu Jing Zhou Yan Wang Wenli Lai Hu Long | 2021 | International Journal of Oral Science2021，13，2： | 0 |
| 6 | Performance optimization of dye-sensitized solar cells by gradient-ascent architecture of SiO_2@Au@TiO_2 microspheres embedded with Au nanoparticles显示文摘Highly homogeneous, well dispersed SiO_2@Au@TiO_2(SAT) microspheres decorated with Au nanoparticles(AuNPs) were prepared and incorporated into the photoanode with an optimized concentration gradientascent. The effects of SAT microspheres and the gradient-ascent architecture on the light absorption and the photoelectric conversion efficiency(PCE) of the dye-sensitized solar cells(DSSCs) were investigated.Studies indicate that the introduction of SAT microspheres and the gradient-ascent architecture in the photoanode significantly enhance the light scattering and harvesting capability of the photoanode. The DSSC with the optimized SAT gradient-ascent photoanode has the maximum short circuit current density(J_(sc)) of 17.7 mA cm^(-2) and PCE of 7.75%, remarkably higher than those of the conventional DSSC by 23.7%and 28.0%, respectively. This significantly enhancement of the performance of the DSSC can be attributed to the excellent light reflection/scattering of SAT, the localized surface plasma resonance(LSPR) effect of AuNPs within the microspheres, and the gradient-ascent architecture of SAT microspheres inside the photoanode. This study demonstrates that the tri-synergies of the scattering of SAT microspheres, the LSPR of AuNPs and the gradient-ascent architecture can effectively improve the PCE of DSSC. | Mingyue Li Na Yuan Yiwen Tang Ling Pei Yongdan Zhu Jiaxian Liu Lihua Bai Meiya Li | 2019 | Journal of Materials Science & Technology2019，35，4： | 0 |
