Massive bleeding and wound infection are the major problems often observed during severe trauma, and achieving rapid hemostasis in cases of high‐dose bleeding in arteries and viscera remains an acute clinical demand. Herein, a mussel‐ and barnacle cement proteins‐inspired dual‐bionic hydrogel is first proposed. Benefiting from abundant phenolic hydroxyl groups, a tough dissipative matrix, removal of interfacial water, as well as dynamic redox balance of phenol‐quinone, the multinetwork hydrogel achieves repeatable robust wet‐tissue adhesiveness (151.40 ± 1.50 kPa), a fast multimodal self‐healing ability, and excellent antibacterial property against both Gram‐positive/negative bacteria. For rabbit/pig models of cardiac penetration holes and femoral artery injuries, the dual‐bionic bioadhesive shows better hemostatic efficiency than commercial gauze due to the synergistic effect of strong wound sealing capability, excellent red blood cell capturing property, and activation of hemostatic barrier membrane. More interestingly, the hydrogel combined with commercial hemostatic sponge presents accelerated wound healing as well as great potential for treating deep‐wound hemorrhage in a battlefield environment. Overall, owing to these unique advantages, the novel tissue‐adhesive hemostat opens up a new avenue to rapid sealing hemostasis and wound healing applications.

Abstract: Hydrostatic guideways are widely applied into precision and ultra-precision machine tools.Meanwhile, the oil film heat transfer causes thermal disturbance to the machine accuracy. Therefore, it is necessary to study the mechanism of the oil film heat transfer and the heat transfer reducing method to improve the machine accuracy. This paper describes a comprehensive thermal FE simulation modeling method for the hydrostatic machine feed platform to study methods of reducing machine thermal errors. First of all, the generating heat power of viscous hydraulic oil flowing between parallel planes is calculated based on Bernoulli equation. This calculation is then employed for the simulation load calculations for the closed hydrostatic guideways, which is adopted by the hydrostatic machine feed platform. Especially, in these load calculations, the changing of oil film thickness (resulted from external loads) and the changing of oil dynamic viscosity (influenced by its temperature) are taken into account. Based on these loads, thermal FE simulation modeling of the hydrostatic machine feed platform is completed to predict and analyze its thermal characteristics. The reliability of this simulation modeling method is verified by experiments. The studies demonstrate that: the hydrostatic machine thermal error degree is determined by the oil film heat transfer scale, and this scale is mainly influenced by the relative oil supply temperature to ambient temperature (quantitative comparison of oil supply temperature and ambient temperature). Furthermore, the r...
