| 1 | Versatile on-chip light coupling and(de)multiplexing from arbitrary polarizations to controlled waveguide modes using an integrated dielectric metasurface显示文摘Metasurfaces have found broad applicability in free-space optics,while its potential to tailor guided waves remains barely explored.By synergizing the Jones matrix model with generalized Snell’s law under the phase-matching condition,we propose a universal design strategy for versatile on-chip mode-selective coupling with polarization sensitivity,multiple working wavelengths,and high efficiency concurrently.The coupling direction,operation frequency,and excited mode type can be designed at will for arbitrary incident polarizations,outperforming previous technology that only works for specific polarizations and lacks versatile mode controllability.Here,using silicon-nanoantenna-patterned silicon-nitride photonic waveguides,we numerically demonstrate a set of chip-scale optical couplers around 1.55μm,including mode-selective directional couplers with high coupling efficiency over 57%and directivity about 23 d B.Polarization and wavelength demultiplexer scenarios are also proposed with 67%maximum efficiency and an extinction ratio of 20 d B.Moreover,a chip-integrated twisted light generator,coupling free-space linear polarization into an optical vortex carrying 1 h orbital angular momentum(OAM),is also reported to validate the mode-control flexibility.This comprehensive method may motivate compact wavelength/polarization(de)multiplexers,multifunctional mode converters,on-chip OAM generators for photonic integrated circuits,and high-speed optical telecommunications. | YUAN MENG ZHOUTIAN LIU ZHENWEI XIE RIDE WANG TIANCHENG QI FUTAI HU HYUNSEOK KIM QIRONG XIAO XING FU QIANG WU SANG-HOON BAE MALI GONG XIAOCONG YUAN | 2020 | Photonics Research2020，8，4： | 8 |
| 2 | Fabrication of Crack-Free Flattened Bamboo and Its Macro-/MicroMorphological and Mechanical Properties显示文摘This work aimed to help the bamboo industry develop methodology for producing imperfection-free bamboo boards that can serve either decorative or structural benefit to consumers seeking to engage with the bioeconomy.Specifically,softened and slotted bamboo tubes were handled by a roller device with nails to render crack-free flattened bamboo board.Softening temperature and time were optimized herein according to findings regarding chemical composition and board mechanical properties.The optimal softening parameters for saturated steam heat treatment is proved to be 160°C for 8 min.The flattened bamboo board possesses an increased bending strength of 101.5 MPa and a decreased bending modulus of 7.7 GPa,being compared with only-softened bamboo.The corresponding changing mechanism is determined in-depth by the micro-morphological and mechanical results based on in-situ SEM and AFM technologies.Under the action of nails and rolling processes,the bamboo texture becomes compact with crushed and fragmented conduit walls.The resulting cell cavity then becomes stretched and compressed,taking on a morphology which allows for the mechanical penalties associated with flattening to be avoided.According to the micro-mechanical results obtained by AFM,compared with unflatten bamboo,the Young’s modulus of the cell membrane in transverse direction(YT)decreases to 1.00 GPa while the corresponding Young’s modulus in radial direction(YR)increases to 7.29 GPa. | Zhichao Lou Tiancheng Yuan Qiuyi Wang Xinwu Wu Shouheng Hu Xiaomeng Hao Xianmiao Liu Yanjun Li | 2021 | Journal of Renewable Materials2021，9，5： | 4 |
| 3 | Monitoring the Amery Ice Shelf front during 2004-2012 using ENVISAT ASAR data显示文摘The Amery Ice Shelf is the largest ice shelf in East Antarctica. It drains continental ice from an area of more than one million square kilometres through a section of coastline that represents approximately 2% of the total circumference of the Antarctic continent. In this study, we used a time series of ENVISAT ASAR images from 2004-2012 and flow lines derived from surface velocity data to monitor the changes in 12 tributaries of the Amery Ice Shelf front. The results show that the Amery Ice Shelf has been expanding and that the rates of expansion differ across the shelf. The highest average annual rate of advance from 2004-2012 was 3.36 m·d-1 and the lowest rate was 1.65 m·d-1 . The rates in 2009 and 2010 were generally lower than those in other years. There was a low correlation between the rate of expansion and the atmospheric temperature recorded at a nearby research station, however the mechanism of the relationship was complex. This study shows that the expansion of the Amery Ice Shelf is slowing down, reflecting a changing trend in climate and ice conditions in East Antarctica. | ZHAO Chen CHENG Xiao HUI Fengming KANG Jing LIU Yan WANG Xianwei WANG Fang CHENG Cheng FENG Zhunzhun CI Tianyu ZHAO Tiancheng ZHAI Mengxi | 2013 | Advances in Polar Science2013，24，2： | 4 |
| 4 | Parathyroid hormone increases alveolar bone homoeostasis during orthodontic tooth movement in rats with periodontitis via crosstalk between STAT3 and β-catenin显示文摘Periodontitis patients are at risk of alveolar bone loss during orthodontic treatment.The aim of this study was to investigate whether intermittent parathyroid hormone(1–34)treatment(iPTH)could reduce alveolar bone loss during orthodontic tooth movement(OTM)in individuals with periodontitis and the underlying mechanism.A rat model of OTM in the context of periodontitis was established and alveolar bone loss was observed.The control,iPTH and iPTH+stattic groups received injections of vehicle,PTH and vehicle,or PTH and the signal transducer and activator of transcription 3(STAT3)inhibitor stattic,respectively.iPTH prevented alveolar bone loss by enhancing osteogenesis and suppressing bone resorption in the alveolar bone during OTM in rats with periodontitis.This effect of iPTH was along with STAT3 activation and reduced by a local injection of stattic.iPTH promoted osteoblastic differentiation and might further regulate the Wnt/β-catenin pathway in a STAT3-dependent manner.The findings of this study suggest that iPTH might reduce alveolar bone loss during OTM in rats with periodontitis through STAT3/β-catenin crosstalk. | Cheng Zhang Tiancheng Li Chenchen Zhou Li Huang Yuyu Li Han Wang Peipei Duan Shujuan Zou Li Mei | 2020 | International Journal of Oral Science2020，12，4： | 4 |
| 5 | Synthesis and properties of a Pr(III) complex with 2-acetyl- benzimidazoledehyde-glycine Schiff-base ligand显示文摘The 2-acetyl-benzimidazoledehyde-gly- cine Schiff-base ligand and the corresponding Pr(III) complex Pr2L3(NO3)3·2CH3OH (L=C11H10N3O2) were synthesized in methanol and characterized by a series of methods, including chemical analysis, elemental analysis, TOF-MS, 1H NMR, UV-, IR-, Raman spectra, thermal analysis, and the three-dimension fluores- cence excitation and emission spectra. The Pr(III) complex exhibits extraordinary water-solubility and the Pr(III) hydroxide appears at pH≥13. The complex also possesses specific fluorescent properties. Thus, at the excitation wavelengths 200.0-280.0 and 260-350 nm the fluorescence bands were observed at 290.0 and 400.0 nm, respectively. | WANG Danghui YANG Yixin YANG Yiqin ZHAO Tiancheng WU Xing WANG Shaokang HOU Yao CHEN Weizong | 2006 | Chinese Science Bulletin2006，51，7： | 3 |

| 7 | PLLA-PCys co-electrospun fibers for capture and elution of glutathione S-transferase显示文摘The copolymer poly(L-lactic acid)-b-poly(L-cysteine) (PLA-b-PCys) was co-electrospun with PLGA into ultrafine fibers. The reduced glutathione (GSH) was conjugated to the fiber surfaces via disulfide bonds. The glutathione S-transferase (GST) was captured onto the GSH fibers via specific substrate-enzyme interaction between the bound GSH and GST. The captured GST was eluted with free GSH aqueous solution and lyophilized to get pure GST powders. The results show that the GSH moieties on the fiber surface retain the bioactivity of the free GSH and thus they can bind specifically with GST and the GST in solution is captured onto the fiber surface. In addition, the bound GSH is not as active as free GSH so that the captured GST can be eluted off from the fiber by free GSH aqueous solution. Based on this principle, GST itself or its fused proteins can be separated and purified very easily. The preliminary purification efficiency is 6.5 mg·(gPCys)-1. Further improvements are undertaken. | LU TianCheng SUN Jing DONG XiaoQing CHEN XueSi WANG Yu JING XiaBin | 2009 | Science China Chemistry2009，52，12： | 3 |
| 8 | SOCS3 Attenuates GM-CSF/IFN-γ-Mediated Inflammation During Spontaneous Spinal Cord Regeneration显示文摘SOCS3,a feedback inhibitor of the JAK/STAT signal pathway,negatively regulates axonal regrowth and inflammation in the central nervous system(CNS).Here,we demonstrated a distinct role of SOCS3 in the injured spinal cord of the gecko following tail amputation.Severing the gecko spinal cord did not evoke an inflammatory cascade except for an injury-stimulated elevation of the granulocyte/macrophage colony-stimulating factor(GM-CSF) and interferon gamma(IFN-γ) cytokines.Simultaneously,the expression of SOCS3 was upregulated in microglia,and unexpectedly not in neurons.Enforced expression of SOCS3 was sufficient to suppress the GMCSF/IFN-γ-driven inflammatory responses through its KIR domain by attenuating the activities of JAK1 and JAK2.SOCS3 was also linked to GM-CSF/IFN-y-induced crosstolerance.Transfection of adenovirus overexpressing SOCS3 in the injured cord resulted in a significant decrease of inflammatory cytokines.These results reveal a distinct role of SOCS3 in the regenerating spinal cord,and provide new hints for CNS repair in mammals. | Xuejie Zhang Bingqiang He Hui Li Yingjie Wang Yue Zhou Wenjuan Wang Tiancheng Song Nan Du Xingxing Gu Yi Luo Yongjun Wang | 2020 | Neuroscience Bulletin2020，36，7： | 3 |
