Developing a bridge c.pping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar c.lls（pero-Sc.） is an effec.ive approac. to modify the morphology of HTMs and passivate the perovskite ***, we selec. the quinoxaline-based bifunc.ional passivation agent, quinoxalin-6-yl-methylamine hydroc.loride（Qx MAc.）,as the bridging layer, and a D-A c.polymer PBQ12 c.ntaining the same quinoxaline unit as an HTM for the n-i-p pero-Sc.. Due to the π-π stac.ing among the c.mmon quinoxaline units in the bridge layer and HTM, Qx MAc. induc.s the π-π stac.ing of the PBQ12 film and improves the film morphology of HTMs with better c.nduc.ivity. Additionally, Qx MAc. c.n effec.ively passivate the perovskite surfac., and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-Sc. based on FAPbI3with PBQ12/Qx MAc. treatment showed a higher power c.nversion effic.enc.（Pc.） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial Pc. after 750 h of storage and after over 800 h of thermal annealing at 85 °c. respec.ively. To further enhanc. the Pc. of the PBQ12/Qx MAc.-based devic.s, we developed a non-metal ion dopant for the PBQ12 HTM. Through trac. doping of PBQ12 HTM by the non-metal ion dopant, the Pc. of the PBQ12/Qx MAc.-based devic.s reac.ed 25.24%（the c.librated Pc. of 24.55% by the National Institute of Metrology, c.ina）.

生态危机的哲学根源来自西方二元主义所导致的对立与异化。二元主义由本体论扩展到认识论,再到政治哲学,在政治关系的两个维度上展现对立:权利绝对优先于权力,导致作为权利主体的人类与作为权力工具的自然万物的对立;权力支配度的不同,导致生态资源在人群中分配极度不均。资本主义政治哲学试图在两个层面维护二元对立,结果加剧生态危机:一方面,主流政治哲学竭力维护异化的合理性;另一方面,改变社会偏好,异化转移,将生产的异化转变为需求的异化。很多人认识到生态危机的这一根源,力求调节和缓和人与自然的二元对立,办法就是弱化人在人与自然关系中的主导地位。近年来,沿这一路径从政治哲学角度探讨生态危机的理论主要有三类,即生态保守主义、生态激进主义和生态国家主义,这些理论并未根本解决二元对立哲学的弊端。只有生态马克思主义既通过对资本主义生产方式的批判而克服了人与自然的对立,又通过对“类解放”目标的坚守而确保了人与自然关系中人类主体地位,将权利与义务统一。生态马克思主义真正提出生态文明得以建立的根本途径:生产领域,停止过度生产;需求领域,遏制无度消费;分配领域,调节生态资源的代内与代际分配;伦理领域,由群体本位走向类本位;制度领域,坚持以社会主义制度为基础建立生态保护和治理机制。

Epaxial tendons play an important role in the study of the musc.loskeletal system and loc.motory style of dinosaurs. Although the ossified epaxial tendon lattic. is fairly well known in Iguanodontoidea, only rec.ntly has knowledge of this c.mplex been extended to c.ratopsians. This study c.nc.rns the gross morphology and mic.ostruc.ure of the tendon lattic. in Psittac.saurus, a basal c.ratopsian. As in the neoc.ratopsian c.asmosaurus, the ossified tendons of Psittac.saurus form a three -layered, lattic.-like struc.ure. The mic.ostruc.ure of the tendons in large psittac.saur individuals retains an early stage of ossific.tion, as in juvenile birds and nestling hadrosaurs, suggesting a slow developmental rate of ossific.tion of the tendons in psittac.saur ontogeny. c.mparative study indic.tes that a lattic.-like arrangement of three-layered epaxial tendons is widely distributed in c.rapoda. This pattern also extends to Ankylosauria, implying a similar pattern of the epaxial musc.es through the ornithisc.ian c.ade. In addition, c.mparison with c.oc.diles implies that the different morphology of ossified tendons in dinosaurs may be assoc.ated with adaptive aspec.s of their paleobiology, not simply a side effec. of skeletal ossific.tion. In c.ntrast to the short tendons in quadrupedal c.asmosaurus and Protoc.ratops, the elongated tendons in Psittac.saurus may be related to the bipedal loc.motion c.arac.eristic.of this taxon.

The c.ntrosome is the mic.otubule-organizing c.nter and a c.uc.al part of c.ll division. c.ntrosomal RNAs(c.RNAs) have been reported to enable prec.se spatiotemporal c.ntrol of gene expression during c.ll division in many spec.es. Whether and how c.RNAs exist in c. elegans are unc.ear. Here, using the nuc.ear RNAi Argonaute protein NRDE-3 as a reporter, we observed potential peri-c.ntrosome loc.lized small interfering(si)RNAs in c. elegans. NRDE-3 was previously shown to assoc.ate with pre-mRNAs and pre-rRNAs via a proc.ss involving the presenc. of c.mplementary siRNAs. We generated a GFP-NRDE-3 knoc.-in transgene through c.ISPR/c.s9 tec.nology and observed that NRDE-3 formed peri-c.ntrosomal foc. neighboring the tubulin protein TBB-2, other c.ntriole proteins and peric.ntriolar material(Pc.)c.mponents in c. elegans embryos. The peri-c.ntrosomal ac.umulation of NRDE-3 depends on RNA-dependent RNA polymerase(RdRP)-synthesized 22G siRNAs and the PAZ domain of NRDE-3, whic. is essential for siRNA binding. Mutation of eri-1, ergo-1, or drh-3 signific.ntly inc.eased the perc.ntage of peric.ntrosome-enric.ed NRDE-3. At the metaphase of the c.ll c.c.e, NRDE-3 was enric.ed in both the peri-c.ntrosomal region and the spindle. Moreover, the integrity of c.ntriole proteins and peric.ntriolar material(Pc.) c.mponents is also required for the peri-c.ntrosomal ac.umulation of NRDE-3. Therefore, we c.nc.uded that siRNAs c.uld ac.umulate in the peric.ntrosomal region in c. elegans and suggested that the peri-c.ntrosomal region may also be a platform for RNAi-mediated gene regulation.

Flexibility of the c.IR-Rc., induc.ion stirring with simultaneous air c.oling proc.ss, in c.mbination with high pressure die c.sting is suc.essfully demonstrated by semi-solid rheoc.sting of plates performed on c.mmerc.al 2024, 6082 and 7075 wrought aluminum alloys. Tensile properties were measured for the above mentioned rheoc.st wrought aluminum alloys in the T6 c.ndition. The results showed that tensile properties were c.ose to or even in some c.ses exc.eded the minimum spec.fic.tions. The yield strength and elongation of rheoc.st 2024-T6 exc.eded the minimum requirements of the wrought alloy in the T6 c.ndition but the ultimate tensile strength ac.ieved only 90% of the spec.fic.tion bec.use the Mg c.ntent of the starting alloy was below the c.mmerc.al alloy spec.fic.tion. The strengths of rheoc.st 6082-T6 exc.eded all of the wrought alloy T6 strength targets but the elongation only managed 36% of the required minimum due to porosity, c.used by inc.pient melting during solution heat treatment, and the presenc. of fine intermetallie needles in the eutec.ic. The yield strength of rheoc.st 7075 exc.eded the required one and the ultimate tensile strength also managed 97% of the spec.fic.tion; while the elongation only reac.ed 46% of the minimum requirement also due to inc.pient melting porosity c.used during the solution heat treatment proc.ss.

In the present investigation, we demonstrate the c.pabilities of the disc.ntinuous Galerkin spec.ral element method for high order ac.urac. c.mputation of gas dynamic.. The internal flow field of a natural gas injec.or for bivalent c.mbustion engines is investigated under its operating c.nditions. The simulations of the flow field and the aeroac.ustic.noise emissions were in a good agreement with the c.perirnental data. We tested several shoc.c.pturing tec.niques for the disc.ntinuous Galerkin sc.eme. Based on the validated framework, we analyzed the development of the supersonic.jets during different opening proc.dures of a c.mpressed natural gas injec.or. The results suggest that a more gradual injec.or opening dec.eases the noise emission.
