Progress in the fast charging of high-capacity silicon monoxide(SiO)-based anode is currently hindered by insufficient conductivity and notable volume expansion.The construction of an interface conductive network effectively addresses the aforementioned problems;however,the impact of its quality on lithium-ion transfer and structure durability is yet to be explored.Herein,the influence of an interface conductive network on ionic transport and mechanical stability under fast charging is explored for the first time.2D modeling simulation and Cryo-transmission electron microscopy precisely reveal the mitigation of interface polarization owing to a higher fraction of conductive inorganic species formation in bilayer solid electrolyte interphase is mainly responsible for a linear decrease in ionic diffusion energy barrier.Furthermore,atomic force microscopy and Raman shift exhibit substantial stress dissipation generated by a complete conductive network,which is critical to the linear reduction of electrode residual stress.This study provides insights into the rational design of optimized interface SiO-based anodes with reinforced fast-charging performance.

Li-rich Mn-based materials provide higher capacity than commercial NCM layered materials due to the synergistic redox effect of cations and anions. However, lattice straining and structural collapse caused by the irreversible oxygen release at high voltage range during cycling, which results in severe capacity and voltage decay. Herein, a synergistic strategy of surface-induced spinel structure and F doping is provided to improve the structural stability. The surface spinel structure helps to reduce the structural collapse caused by electrolyte corrosion on the cathode and effectively inhibits voltage decay resulted from structural evolution. The stronger Mn-F bonds are formed by F doping to inhibit migration of transition metal(TM) and induce the uniform deposition of Li F to form the thinner and more stable CEI on the cathode. Accordingly, the designed cathode(LMNO-NF) shows remarkable cycling performance with the capacity retention of 86.68 % and voltage retention of 96.6 % for 200 cycles at 1C,higher than pristine material(68.76 % and 85.75 %). Therefore, this simple dual-modification strategy of one-step synthesis is promising for solving the structural evolution and voltage decay of Li-rich Mn-based cathode materials effectively, achieving further commercialization.

土壤水分与全球气候变化、碳循环、水循环等过程,以及农业生产、生态保护修复等环节密切相关。土壤水分的探测经历了从地面测量到遥感探测的发展过程,实现了全球及区域尺度的调查监测。由于数据谱段不一、辐射传输机制不同、反演算法多样,需从算法机理、优势、局限等角度进行全面分析,为精度提升、算法改进提供基础。为此,该文从光学遥感、微波遥感、光学微波协同3个方面,系统梳理了光学遥感温度-植被指数空间特征、温度-地表短波净辐射时间特征反演土壤水分,被动、主动微波反演和主、被动微波遥感联合反演,以及基于精度改善和时空尺度转化的光学微波协同反演等技术方法的特点、存在的问题。目前,多源遥感数据联合反演土壤水分主要存在如下问题:①数据存在缺失及时空尺度不匹配问题;②不同数据源对地表穿透性不一致;③联合反演模型依赖于经验参数和大量辅助参数。随着卫星监测网络的完善、数据源对地表探测深度研究的深入,以及联合反演物理机理的明确、辅助参数时空连续数据集的建立,上述问题会得到有效解决。

Photosystem Ⅱ(PSⅡ)is a multi-subunit protein complex of the photosynthetic electron transport chain that is vital to photosynthesis.Although the structure,composition,and function of PSⅡ have been extensively studied,its biogenesis mechanism remains less understood.Thylakoid rhodanese-like(TROL)provides an anchor for leaf-type ferredoxin:NADP^(+)oxidoreductase.Here,we report the chacterizaton of a second type of TROL protein,TROL2,encoded by seed plant genomes whose function has not previously been reported.We show that TROL2 is a PSⅡ assembly cofactor with essential roles in the establishment of photoautotrophy.TROL2 contains a 45-amino-acid domain,termed the chlorotic lethal seedling(CLS)domain,that is both necessary and sufficient for TROL2 function in PSⅡ assembly and photoautotrophic growth.Phylogenetic analyses suggest that TROL2 may have arisen from ancestral TROL1 via gene duplication before the emergence of seed plants and acquired the CLS domain via evolution of the sequence encoding its N-terminal portion.We further reveal that TROL2(or CLS)forms an assembly cofactor complex with the intrinsic thylakoid membrane protein LOW PSⅡ ACCUMULATION2 and interacts with small PSⅡ subunits to facilitate PSⅡ complex assembly.Collectively,our study not only shows that TROL2(CLS)is essential for photoautotrophy in angiosperms but also reveals its mechanistic role in PSⅡ complex assembly,shedding light on the molecular and evolutionary mechanisms of photosynthetic complex assemblyin angiosperms.

Clostridium butyricum has been widely considered an antibiotic substitute in recent years.It can promote growth performance,improve the immune response and enhance the intestinal barrier function of the host.In the present study,1-d-old Arbor Acres(AA)broilers were fed C.butyricum(1×109 cfu/kg)for 28 d.The transcriptomic characteristics of epithelial cells of the cecal mucosa were determined by RNA-sequence,and the cecal microbiota composition was explored by 16 S ribosomal RNA gene sequencing.The changes in the intestinal mucosa of broilers were then analyzed by tissue staining.Gene Ontology(GO)annotations identified substance transport and processes and pathways that might participate in intestinal development and cell viability.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis revealed that the differentially expressed genes are involved in numerous pathways related to amino acid and vitamin metabolism and antioxidant and defensive functions,among others.The relative expression of some genes associated with intestinal barrier function(claudins 2,15,19,and 23,tight junction proteins 1,2,and 3 and mucin 1)was significantly increased in the treatment group(P<0.05 or P<0.01).Moreover,the proportion of Firmicutes was higher in the C.butyricum-treated group,whereas the proportion of Proteobacteria was higher in the control group.At the genus level,the relative abundances of Butyricicoccus and Lactobacillus,among other bacteria,were increased after C.butyricum supplementation.The tissue staining analysis showed that the cecal mucosa of broilers was significantly ameliorated after the addition of C.butyricum(P<0.05 or P<0.01).These results showed that dietary supplementation with C.butyricum can enhance the antioxidant capacity,mucosal barrier function,and stabilize the cecal microbiota,resulting in improving the growth performance.

Based on the experimental data,this study investigated the effect of sand content of muddy water on water and nitrogen transport characteristics of the single-line interference infiltration under film hole irrigation with muddy water and fertilizer.The relationship between the single-line interference infiltration parameters,the sand content,the wetting front movement distances,and the sand content were all established.The model of the cumulative infiltration volume of per unit film pore area,the vertical and horizontal wetting front movement distance of the free surface,and the wetting front movement distance of the interference center with sand content and infiltration time were proposed.Reveal the law of the change of soil water content and the distribution of NO_(3)^(-)-N content based on different muddy water sand content.The results indicate that at the same infiltration time,as the muddy water sand content increases,the cumulative infiltration volume per unit pore area decreases.The infiltration index of the free infiltration and the single-line interference vary little when the sand content increases,mainly are around 0.64 and 0.58.The relationship between infiltration parameters a,b and the sand content is linear function.At the same location,the more the sand content,the smaller the wetting front movement distance in free surface and the single-line interference surface,the less the NO_(3)^(-)-N content.

Ce^(3+) sensitized Tb^(3+) and Dy^(3+) photoluminescence in β-LaB_(5)O_(9) prepared by sol-gel method

引用

Journal of Rare Earths 2022年第8期40卷 1181-1186页

作者： Yuxuan Qi ruirui Yang Yan Gao Pengfei jiang Rihong Cong Tao Yang College of Chemistry and Chemical Engineering Chongqing UniversityChongqing 401331China

Rare earth(RE) pentaborates,both α-and β-polymorphs,are good candidates for photoluminescent hosts suitable for various RE activators,Ce^(3+) acts not only as an activator itself,but also as a sensitizer to other rare earth activators,like in the case of commercial green phosphor CeMgAl_(11)O_(19):Tb^(3+).In this work,two solid solutions of β-La_(0.9-x)Ce_(0.1)Tb_(x)B_(5)O_(9)(0≤x≤0.15) and β-La_(0.9-y)Ce_(0.1)Dy_(y)B_(5)O_(9)(0≤y≤0.07)were prepared by sol-gel method with high crystallinity,and the phase purity was confirmed with careful analyses on powder X-ray diffraction patterns.Energy transfers are expected due to the overlapping of Ce^(3+)emission with the Tb^(3+)/Dy^(3+)excitation.Indeed,the steady photoluminescence spectra indicate the decrease of the Ce^(3+)emission and the increase of the Tb^(3+)/Dy^(3+) emission,and the fluorescence decay curves exhibit the decrease of the average lifetime of Ce^(3+).The energy transfer efficiency is estimated to be 60% at χ=0.15 and 55% at y=0.07,respectively.The mechanism is likely through the dipole-dipole electric interactions for both cases.With this rationale,the Tb^(3+)and Dy^(3+)emissions are greatly enhanced,in particular,the white emission of Dy^(3+)in β-La_(0.85)Ce_(0.1)Dy_(0.05)B_(5)O_(9) is enhanced by 20 times.
