| 1 | Biomass-based aligned carbon networks with double-layer construction for tunable electromagnetic shielding with ultra-low reflectivity显示文摘Nowadays,carbon frameworks derived from natural biomaterials have attracted extensive attention for electromagnetic interference(EMI)shielding due to their renewability and affordability.However,it is critical and challenging to achieve effective regulation of shielding effectiveness(SE)as well as weaken the strong EM reflection of highly conductive biomass-based carbon materials.Herein,commercial cotton pads with oriented structure were selected as carbonaceous precursor to fabricate aligned carbon networks by pyrolysis,and the EMI SE of the samples with increased temperature of 800-1000℃ can be accurately controlled in the effective range of~21.7-29.1,~27.7-37.1 and~32.7-43.3 d B with high reflection coefficient of>0.8 by changing the cross-angle between the electric-field direction of incident EM waves and the fiber-orientation direction due to the occurrence of opposite internal electric field.Moreover,the further construction of Salisbury absorber-liked double-layer structure could result in an ultralow reflection coefficient of only~0.06 but enhanced SE variation range up to~38.7-49.3 d B during the adjustment of cross-angle,possibly due to the destructive interference of EM waves in the double-layer carbon networks.This work would provide a simple and effective way for constructing high-performance biomass carbon materials with adjustable EMI shielding and ultra-low reflectivity. | Jiali Chen Da Yi Xichen Jia Guoqing Wang Zhouping Sun Lihua Zhang Yinfeng Liu Bin Shen Wenge Zheng | 2022 | Journal of Materials Science & Technology2022，，8： | 2 |

| 6 | Dynamics of ecosystems and anthropogenic drivers in the Yellow Sea Large Marine Ecosystem显示文摘In the developed world,governance of marine ecological environment is the important part of the national ecological and economic outcome.The Yellow Sea is one of large marine ecosystems in the seas of East Asia,which is an extension of one of the largest continental shelf areas,and forms a huge but shallow sediment body in its south area which is geographically unique in the world.As a region with the most fragile natural environment,unparalleled global ecological significance and the most urgent protection needs,the Yellow Sea ecological zone is becoming a common concern of countries around the Yellow Sea and beyond,such as tidal flats and the staging migratory birds(Murray et al.,2015). | Jun Sun Yinfeng Guo Gyung Soo Park Andrew Hudson | 2022 | Acta Oceanologica Sinica2022，41，6： | 1 |

| 8 | Investigation on the Tensile Properties and Fracture Characteristics of Amorphous Ribbons Fe81.50B1.40Si7.95Nb7.37Cu1.73P0.05显示文摘A number of Fe-Si-B amorphous ribbons are made by using melt spinning method. The microstructure, mechanical and other relevant properties of thin amorphous ribbons of Fe81.50B1.40Si7.95Nb7.37Cu1.73P0.05 alloy at room temperature were studied with several equipment including Differential scanning calorimetry (DSC), X-ray diffraction (XRD),Scanning electron microscope (SEM), and tensile machine. Significantly different microstructures exist between the free and wheel face of the thin amorphous ribbons. The free face is smooth while the wheel face is coarse with a great number of micro voids on the surface. Experimental results show that the tensile strength and elastic modulus of thethin amorphous ribbons at room temperature are 1951 MPa and 70 GPa. In addition, the amorphous ribbons possess reasonable tensile elongation (2.46%). The fracture appearance of amorphous ribbons of Fe81.50B1.40Si7.95Nb7.37Cu1.73P0.05 alloyis a mixed mode of ductile and brittle fracture which includes dimples and partial cleavage fracture similar to the crystalline materials. The dimple feature proves that it still has plastic characteristics on the micro scale. | Sheng Lei Jun Sun Yinfeng Zhu Huaqi Liang Yansheng Yao Rong Hu | 2019 | Journal of Harbin Institute of Technology(New Series)2019，26，6： | 0 |
