Vanadium oxides,par-ticularly hydrated forms like V_(2)O_(5)·nH_(2)O(VOH),stand out as promising cathode candidates for aqueous zinc ion batteries due to their adjustable layered structure,unique electronic characteristics,and high theoretical capacities.However,challenges such as vanadium dissolution,sluggish Zn^(2+)diffusion kinetics,and low operating voltage still hinder their direct application.In this study,we present a novel vanadium oxide([C_(6)H_(6)N(CH_(3))_(3)]_(1.08)V_(8)O_(20)·0.06H_(2)O,TMPA-VOH),developed by pre-inserting trimethylphenylammonium(TMPA+)cations into VOH.The incorporation of weakly polarized organic cations capitalizes on both ionic pre-intercalation and molecular pre-intercalation effects,resulting in a phase and morphology transition,an expansion of the interlayer distance,extrusion of weakly bonded interlayer water,and a substantial increase in V^(4+)content.These modifications synergistically reduce the electrostatic interactions between Zn^(2+)and the V-O lattice,enhancing structural stability and reaction kinetics during cycling.As a result,TMPA-VOH achieves an elevated open circuit voltage and operation voltage,exhibits a large specific capacity(451 mAh g^(-1)at 0.1 A g^(-1))coupled with high energy efficiency(89%),the significantly-reduced battery polarization,and outstanding rate capability and cycling stability.The concept introduced in this study holds great promise for the development of high-performance oxide-based energy storage materials.

Neutrophils are predominant leukocytes in the circulation,which are essential for killing invading pathogens via the activation of effector responses and the production of reactive oxygen species(ROS),also named as"oxidative burst."When infected,activated neutrophils fight bacteria,fungi,and viruses through oxidative burst,phagocytosis,degranulation,and the production of neutrophil extracellular traps(NETs)in a neutrophil death process named as"NETosis"(Mutua and Gershwin,2021).

Cancer therapy is undergoing a paradigm shift toward immunotherapy focusing on various approaches to activate the host immune system.As research to identify appropriate immune cells and activate anti-tumor immunity continues to expand,scientists are looking at microbial sources given their inherent ability to elicit an immune response.Bacterial extracellular vesicles(BEVs)are actively studied to control systemic humoral and cellular immune responses instead of using whole microorganisms or other types of extracellular vesicles(EVs).BEVs also provide the opportunity as versatile drug delivery carriers.Unlike mammalian EVs,BEVs have already made it to the clinic with the meningococcal vaccine(Bexsero®).However,there are still many unanswered questions in the use of BEVs,especially for chronic systemically administered immunotherapies.In this review,we address the opportunities and challenges in the use of BEVs for cancer immunotherapy and provide an outlook towards development of BEV products that can ultimately translate to the clinic.

With increasing concerns on the environment and human health,the degradation of glyphosate through the formation of less toxic intermediates is of great importance.Among the developed methods for the degradation of glyphosate,photodegradation is a clean and efficient strategy.In this work,we report a new photocatalyst by doping F ion on BiVO_(4) that can efficiently degrade glyphosate and reduce the toxic emissions of aminomethylphosphonic acid(AMPA)through the selective(P)−C−Ncleavage in comparison of BiVO_(4) catalyst.The results demonstrate that the best suppression of AMPA formation was achieved by the catalyst of 0.3F@BiVO_(4) at pH=9(AMPA formation below10%).In situ attenuated total reflectance Fourier transforms infrared(ATR-FTIR)spectroscopy indicates that the adsorption sites of glyphosate on BiVO_(4) and 0.3F@BiVO_(4) are altered due to the difference in electrostatic interactions.Such an absorption alteration leads to the preferential cleavage of the C−Nbond on the N−C−P skeleton,thereby inhibiting the formation of toxic AMPA.These results improve our understanding of the photodegradation process of glyphosate catalyzed by BiVO_(4)-based catalysts and pave a safe way for abiotic degradation of glyphosate.

Frontiers of Computer Science 2022年第1期16卷 1-9页

作者： Huiqun WANG Di Huang Yunhong WANG Laboratory of Intelligent Recognition and Image Processing School of Computer Science and EngineeringBeihang UniversityBeijing100191China

In this paper,we propose a novel and effective approach,namely GridNet,to hierarchically learn deep representation of 3D point clouds.It incorporates the ability of regular holistic description and fast data processing in a single framework,which is able to abstract powerful features progressively in an efficient way.Moreover,to capture more accurate internal geometry attributes,anchors are inferred within local neighborhoods,in contrast to the fixed or the sampled ones used in existing methods,and the learned features are thus more representative and discriminative to local point *** delivers very competitive results compared with the state of the art methods in both the object classification and segmentation tasks.

OBJECTIVE: The purpose of this research is to study the effect of Roucongrong(Herba Cistanches Deserticolae) on reproductive toxicity in mice induced by a glycoside extracted from Leigongteng(Radix et Rhizoma Tripterygii)(GRT).METHODS: Forty-eight BALB/c mice were randomly divided into two groups in the ratio of 1∶3, 12 in one group and 36 in the other. The 12-mouse group was the control group that wasintragastrically administered physiological saline for 3 weeks.The 36 mice in the other group were given 30 mg·kg﹣1·d﹣1GRT for 3 weeks, then randomly divided into 3 subgroups: the model group, GRT group and Roucongrong(Herba Cistanches Deserticolae)group, with 12 mice in each group. In the model group, 0.25 mL physiological saline was intragastrically administered; in the GRT group, GRT, 0.25 mL at 30 mg·kg﹣ 1·d﹣ 1was intragastrically administered once a day; in the Roucongrong(Herba Cistanches Deserticolae) group, mice were administered Roucongrong(Herba Cistanches Deserticolae)decoction equivalent to 0.25 mL at a final dose of10 g·kg﹣ 1·d﹣ 1crude drug(calculated as per 20timesof0.5g·kg﹣1·d﹣1foradults),and GRT 0.25mL at 30 mg·kg﹣1·d﹣1daily. After another 3 weeks of exposure, expression levels of the reproduction-related genes DEAD(Asp-Glu-Ala-Asp) box polypeptide 3, Y-linked, B-cell CLL/lymphoma 6 and Signal transducer and activator of transcription 3 were evaluated.RESULTS:After 6 weeks of GRT treatment,the spermatogenic cell population in the convoluted tubule of testis was in disorder and the tubule cavity expanded. Sertoli cell and Leydig cells exhibited atrophy or disappeared. The number of sperm decreased. The spermatogenic cell level of testis for male mice was ranked in order and sperm was produced in the cavity of the spermatogenic cell. The expression levels of DDX3Y, BCL6 and STAT3 were up-regulated.CONCLUSION: GRT affected reproduction-related genes. Roucongrong(Herba Cistanches Deserticolae) reversed reproductive toxicity in mice induced byGRT.

Tuning heat transport via coherent structure manipulation:recent advances in thermal turbulence

National Science Review 2023年第6期10卷 245-257页

作者： Ke-Qing Xia Shi-Di Huang Yi-Chao Xie Lu Zhang Center for Complex Flows and Soft Matter Research and Department of Mechanics and Aerospace Engineering Southern University of Science and Technology State Key Laboratory for Strength and Vibration of Mechanical Structures and School of Aerospace Xi'an Jiaotong University

Tuning transport properties through the manipulation of elementary structures has achieved great success in many areas,such as condensed matter physics.However,the ability to manipulate coherent structures in turbulent flows is much less explored.This article reviews a recently discovered mechanism of tuning turbulent heat transport via coherent structure manipulation.We first show how this me chanism can be realized by applying simple geometrical confinement to a classical thermally driven turbulence, which leads to the condensation of elementary coherent structures and significant heat-transport enhancement,despite the resultant slower flow.Some potential applications of this new paradigm in passive heat management are also discussed.We then explain how the heat transport behaviors in seemingly different turbulence systems can be understood by this unified framework of coherent structure manipulation.Several future directions in this research area are also outlined.

This study aimed to restore the ultimate strength of dented stainless-steel hemispheres with a radius of 90 mm and a thickness of 0.86 mm.All of the hemispheres were subjected to external hydrostatic pressure.Small stainless-steel stiffened caps were used to eliminate the effect of indention on the ultimate strength.These caps had a radius of 36 mm,a thickness of 0.76 mm,and a height of 10.44 mm.Six hemispherical samples,including two intact hemispheres,two dented hemispheres without stiffening,and two dented hemispheres with stiffening,were prepared.Each hemi-sphere was geometrically measured for shape and thickness,hydrostatically tested for destruction,and numerically evaluated for comparison.The experimental and numerical data agreed well with each other.As a result,a spherical cap can effectively restore the ultimate strength of dented hemispheres under external hydrostatic pressure.The proposed restoration approach can be used to strengthen underwater pressure hulls with large local geometric imperfections.
