In this study,the anti-penetration performance of polyurea/ASTM1405-steel composite plate subjected to high velocity projectile was analyzed.Two kinds of modified polyurea material(AMMT-053 and AMMT-055)were selected and a ballistic impact testing system including speed measuring target system and high-speed camera was designed.This experiment was conducted with a rifle and 5.8 mm projectile to explore the effects by the polyurea coating thickness,the polyurea coating position and the glass-fiber cloth on the anti-penetration performance of polyurea/ASTM1405-steel composite plate.The result showed that the effects of polyurea coating position were different between two types of polyurea,and that the effects of glass-fiber position were disparate between two types of polyurea as well.For AMMT-053 polyurea material,it was better to be on front face than on rear face;whereas for AMMT-055 polyurea,it was better to be on rear surface although the difference was very subtle.Additionally,formulas had been given to describe the relationship between the effectiveness of polyurea and the thickness of polyurea coating.In general,AMMT-055 had better anti-penetration performance than AMMT-053.Furthermore,five typical damage modes including self-healing,crack,local bulge,spallation and local fragmentation were defined and the failure mechanism was analyzed with the results of SHPB test.Additionally,the bonding strength played an important role in the anti-penetration performance of polyurea/steel composite plate. 展开更多

High-efficiency single crystal cascaded third-harmonic generation(THG)was realized inβ-BaB_(2)O_(4)(BBO)material with special cut-angle.By analyzing effective nonlinear optical coefficient(d_(eff))of the cascaded THG process,which was composed by type-II frequency doubling and type-I sum-frequency,the optimum phase matching(PM)direction in BBO crystal was determined to be(θ=32.1°,φ=11°).With an optimized 9-mm long sample which was processed along this direction,the highest cascaded THG conversion efficiency reached 42.3%,which is much superior to the similar components reported previously,including ADP,KDP,and Gd_(x)Y_(1-x)COB crystals. 展开更多

Immunotherapy is a revolutionized therapeutic strategy for tumor treatment attributing to the rapid development of genomics and immunology,and immune checkpoint inhibitors have successfully achieved responses in numbers of tumor types,including hematopoietic malignancy.However,acute myeloid leukemia(AML)is a heterogeneous disease and there is stll a lack of systematic demonstration to apply immunotherapy in AML based on PD-1/PD-L1 blockage. 展开更多

The World Health Organization emphasized the importance of goggles and face shields for protection of medical personnel at the outbreak of the COVID-19 pandemic.Unsurprisingly,almost all countries suffered from a critical supply shortage of goggles and face shields,as well as many other types of personal protective equipment(PPE),for a long period,owing to the lack of key medical material supplies and the inefficiency of existing fabrication methods arising from the need to avoid crowds during the outbreak of COVID-19.In this paper,we propose a novel combined shield design for eye and face protection that can be rapidly fabricated using three-dimensional printing technology.The designed prototype eye-face shield is accessible to the general public,offering more possibilities for yield improvement in PPE during emergent infectious disease events such as COVID-19. 展开更多
