This paper reports a novel manufacturing process of preparing the Three-Dimensional Multiaxial Braided Composites(3DMBCs) and the effects of various defects generated in the manufacturing process on the compressive mechanical properties of 3DMBCs through the experimental and numerical methods. The five-step fabrication process of the 3D multiaxial braided preform was firstly introduced in detail. Then, the influences of various defects such as voids, waviness, and fiber breakage defects on the compressive properties of 3DMBCs were discussed. It is found that the fiber breakage defect and waviness defects were the two primary factors on the decrease of compressive properties of 3DMBCs. However, void defects in the resin and interface had little effect on the composites. When the fiber breakage defect content was 25% and the waviness was 7°, the composite compressive modulus decreased by 51%. The progressive damage process and failure mechanism of the composite under 90° compressive loading confirmed the validity of the numerical model by comparing with the experiments.

痛风的病因为外感风寒,内蕴痰湿,病理基础为痰浊和瘀血,为本虚标实之证,以浊瘀痹阻为标,脾肾不足为本。临证从“浊瘀”立论,以泻浊化瘀为总法,将调益脾肾、培补正气贯穿治疗始终,注重内外配合增强疗效,辨证运用清热祛湿,补脾益肾等治法,方选自拟痛风汤。痛风急性期以标实为主,因湿热搏结于关节而致局部红肿、发热伴剧烈疼痛,故在治疗上主要选取泻化湿浊药物,配合活血行气之品,促进湿浊泻化,缓解疼痛;痛风缓解期虽少有疼痛症状,但由于瘀血阻络,湿浊瘀互结,深居筋骨关节,局部则出现肿胀畸形,因此治疗宜以扶正为主,兼化瘀之法,通过补益人体正气,推陈致新,促进瘀结之溶解。

Postoperative tumor recurrence remains a predominant cause of treatment failure. In this study, we developed an in situ injectable hydrogel, termed MPB-NO@DOX + ATRA gel, which was locally formed within the tumor resection cavity. The MPB-NO@DOX + ATRA gel was fabricated by mixing a thrombin solution, a fibrinogen solution containing all-trans retinoic acid (ATRA), and a Mn/NO-based immune nano-activator termed MPB-NO@DOX. ATRA promoted the differentiation of cancer stem cells, inhibited cancer cell migration, and affected the polarization of tumor-associated macrophages. The outer MnO2 shell disintegrated due to its reaction with glutathione and hydrogen peroxide in the cytoplasm to release Mn2+ and produce O2, resulting in the release of doxorubicin (DOX). The released DOX entered the nucleus and destroyed DNA, and the fragmented DNA cooperated with Mn2+ to activate the cGAS-STING pathway and stimulate an anti-tumor immune response. In addition, when MPB-NO@DOX was exposed to 808 nm laser irradiation, the Fe-NO bond was broken to release NO, which downregulated the expression of PD-L1 on the surface of tumor cells and reversed the immunosuppressive tumor microenvironment. In conclusion, the MPB-NO@DOX + ATRA gel exhibited excellent anti-tumor efficacy. The results of this study demonstrated the great potential of in situ injectable hydrogels in preventing postoperative tumor recurrence.

Full-spectrum phosphor-converted white-light-emitting diodes（pc-WLED） are emerging as a mainstream technology in semiconductor lighting.Nevertheless,high-performance blue phosphor which can be excited efficiently by a 400 nm NUV diode chip is still lacking.Herein,we present a blue-emitting Na3KMg7（PO4）6:Eu2+phosphor synthesized by the solid-reaction method.Particularly,we find that the using of Li2CO3as flux can significantly improve the crystal quality and thus the emission efficiency of the phosphor.Meanwhile,the excitation peak of the phosphor shifts from 365 to 400 nm,which is pivotal for efficient NUV（400 nm） diode chip excitation.The practical Eu2+concentration is also enhanced by using Li2CO3as flux,and the absorption efficiency is greatly increased.This phosphor exhibits superior PL the rmal stability,na mely retains 94% integrated photoluminescence intensity at 150℃of that at 25℃.As a result,the optimized phosphor shows an emission band peaked at 437 nm with a bandwidth of 40 nm and a high external photoluminescence quantum yield of 51.7%.Finally,a pc-WLED was fabricated by using NKMPO:Eu2+blue,Sr2SiO4:Eu2+green,CaAlSiN3:Eu2+red phosphors,and a400 nm NUV diode chip.It shows a high color rendering index of Ra=96.4 and a correlated color temperature of 4358 K.These results prove that NKMPO:Eu2+is a promising blue phosphor for fullspectrum WLED based on NUV diode chips.

Heat is almost everywhere.Unlike electricity,which can be easily manipulated,the current ability to control heat is still highly limited owing to spontaneous thermal dissipation imposed by the second law of thermodynamics.Optical illumination and pressure have been used to switch endothermic/exothermic responses of materials via phase transitions;however,these strategies are less cost-effective and unscalable.Here,we spectroscopically demonstrate the glassy crystal state of 2-amino-2-methyl-1,3-propanediol(AMP)to realize an affordable,easily manageable approach for thermal energy recycling.The supercooled state of AMP is so sensitive to pressure that even several megapascals can induce crystallization to the ordered crystal,resulting in a substantial temperature increase of 48 K within 20 s.Furthermore,we demonstrate a proof-of-concept device capable of programable heating with an extremely high work-to-heat conversion effi-ciency of383.Such delicate and efficient tuning of heat may remarkably facilitate rational utilization of waste heat.
