Abstract: The present application provides a comfortable lightweight bullet-proof and stab-resistant suit and a preparation method thereof. A first aspect of the present application provides a comfortable lightweight bullet-proof and stab-resistant suit, including a sheath and a protection core sheet disposed in the sheath, and the protection core sheet includes a first protection layer, a second protection layer, a third protection layer and a buffer layer which are sequentially stacked together. The bullet-proof and stab-resistant suit provided in the present application has better response protection characteristics in the process of bullet penetration or knife tip stab, and the prepared aramid unidirectional cloth has low areal density, apparent flatness, no bubbles, and excellent softness, so that any bending within 180° can be realized.

Abstract: Provided are an anti-FXI/FXIa antibody, an antigen-binding fragment thereof, and a pharmaceutical use thereof, as well as a pharmaceutical composition comprising the anti-FXI/FXIa antibody or the antigen-binding fragment thereof, and a method for treating and preventing a disease, in particular a method for treating thrombosis or thromboembolism-related diseases or disorders.

Abstract: The invention discloses the application of carbon nanotube assemblies to the preparation of a nanocarbon impact-resistant material. The carbon nanotube assembly is a macrostructure provided with at least one continuous surface, a plurality of carbon nanotubes are densely distributed in the continuous surface, and at least partial segments of at least part of the multiple carbon nanotubes continuously extend in the continuous surface. The invention further discloses a preparation method of the nanocarbon impact-resistant material. The nanocarbon impact-resistant material has an excellent protection effect, has the advantages of being light, good in flexibility, wide in tolerable temperature range, capable of being bent freely, good in fitness, breathable, adaptable to heat-moisture balance of human bodies, good in wearing comfort and the like, and can be widely applied to bullet-proof materials, stab-proof materials and explosion-proof materials.
