Because of the low price and abundant reserves of sodium compared with lithium,the research of sodium-ion batteries(SIBs)in the field of large-scale energy storage has returned to the research spotlight.Layered oxides distinguish themselves from the mains cathode materials of SIBs owing to their advantages such as high specific capacity,simple synthesis route,and environmental benignity.However,the commercial development of the layered oxides is limited by sluggish kinetics,complex phase transition and poor air stability.Based on the research ideas from macro-to micro-scale,this review systematically summarizes the current optimization strategies of sodium-ion layered oxide cathodes(SLOC)from different dimensions:microstructure design,local chemistry regulation and structural unit construction.In the dimension of microstructure design,the various structures such as the microspheres,nanoplates,nanowires and exposed active facets are prepared to improve the slow kinetics and electrochemical performance.Besides,from the view of local chemistry regulation by chemical element substitution,the intrinsic electron/ion properties of SLOC have been enhanced to strengthen the structural stability.Furthermore,the optimization idea of endeavors to regulate the physical and chemical properties of cathode materials essentially is put forward from the dimension of structural unit construction.The opinions and strategies proposed in this review will provide some inspirations for the design of new SLOC in the future.

P2-type layered oxide, Na2/3Ni1/3Mn2/3O2, has drawn particular interest as a promising cathode material for sodium-ion batteries(SIBs) due to its fast sodium-ion transport channels with low migration potential. However, some catastrophic flaws, such as air instability, complicated multiphase evolution, and irreversible anionic redox, limit its electrochemical performance and hinder its application. Here, an air-stable single-crystal P2-type Na2/3Ni1/3Mn1/3Ti1/3O2is proposed based on the multifunctional structural modulation of Ti substitution that could alleviate the issues for practical SIBs. As a result, the cathode with high energy density shows excellent air stability and highly reversible phase transitions(P2–OP4), and delivers faster kinetics and stable anion redox chemistry. Meanwhile, a thorough investigation of the relationship between structure, function, and properties is demonstrated,emphasizing formation processes, electrochemical behavior, structural evolution, and air stability. Overall, this study provides the direction of multifunctional structural modulation for the development of high-performance sodium-based layered cathode materials for practical applications.

Background:Copper and zinc are involved in the development of multiple malignancies;yet,epidemiological evidence on hepatocellular carcinoma(HCC)is limited.This study aimed to investigate the association between dietary intake and serum levels of copper and zinc with the risk of HCC.Methods:A total of 434 case-control pairs matched for sex and age(±1 year)were included in this study.Cases with newly diagnosed HCC were from the Guangdong Liver Cancer Cohort(GLCC)study,and healthy controls were from the Guangzhou Nutrition and Health Study(GNHS).A semi-quantitative 79-item food frequency questionnaire(FFQ)was used to assess habitual dietary intakes of copper and zinc.Serum levels of copper and zinc were measured by using inductively coupled plasma mass spectrometry.The copper(Cu)/zinc(Zn)ratio was computed by dividing copper levels by zinc levels.Conditional logistic regression models were performed to calculate the odds ratio(OR)and 95%confidence intervals(CI)for per 1 standard deviation increase(per-SD increase)in copper and zinc levels.Results:Higher dietary intake(OR_(per-SD increase)=0.65,95%CI:0.44,0.96,P_(trend)=0.029)and serum levels of zinc(OR_(per-SD increase)=0.11,95%CI:0.04,0.30,P_(trend)<0.001)were both associated with a lower risk of HCC.Subgroup analyses showed that the inverse association was only pronounced in men but not in women(P_(interaction)=0.041 for dietary zinc intake and 0.010 for serum zinc levels).Serum copper levels(OR_(per-SD increase)=2.05,95%CI:1.39,3.03,P_(trend)=0.020)and serum Cu/Zn ratio(OR_(per-SD increase)=6.53,95%CI:2.52,16.92,P_(trend)<0.001)were positively associated with HCC risk,while dietary copper intake and dietary Cu/Zn ratio were not associated with HCC risk.Conclusion:Zinc may be a protective factor for HCC,especially among men,but the effects of copper on HCC risk are not clear.

Objective Renal fibrosis is the ultimate pathway of various forms of acute and chronic kidney damage.Notably,the knockout of transient receptor potential channel 6(TRPC6)has shown promise in alleviating renal fibrosis.However,the regulatory impact of TRPC6 on renal fibrosis remains unclear.Methods In vivo,TRPC6 knockout(TRPC6−/−)mice and age-matched 129 SvEv(WT)mice underwent unilateral renal ischemia-reperfusion(uIR)injury surgery on the left renal pedicle or sham operation.Kidneys and serum were collected on days 7,14,21,and 28 after euthanasia.In vitro,primary tubular epithelial cells(PTECs)were isolated from TRPC6−/−and WT mice,followed by treatment with transforming growth factorβ1(TGFβ1)for 72 h.The anti-fibrotic effect of TRPC6−/−and the underlying mechanisms were assessed through hematoxylin-eosin staining,Masson staining,immunostaining,qRT-PCR,and Western blotting.Results Increased TRPC6 expression was observed in uIR mice and PTECs treated with TGFβ1.TRPC6−/−alleviated renal fibrosis by reducing the expression of fibrotic markers(Col-1,α-SMA,and vimentin),as well as decreasing the apoptosis and inflammation of PTECs during fibrotic progression both in vivo and in vitro.Additionally,we found that the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)/glycogen synthase kinase 3 beta(GSK3β)signaling pathway,a pivotal player in renal fibrosis,was down-regulated following TRPC6 deletion.Conclusion These results suggest that the ablation of TRPC6 may mitigate renal fibrosis by inhibiting the apoptosis and inflammation of PTECs through down-regulation of the PI3K/AKT/GSK3βpathway.Targeting TRPC6 could be a novel therapeutic strategy for preventing chronic kidney disease.

Discontinuous phase diagram of amorphous carbons

National Science Review 2024年第4期11卷 164-171页

作者： YinBo zhu ZhouYu fang ZhongTing Zhang HengAn Wu CAS Key Laboratory of Mechanical Behavior and Design of Materials Department of Modern MechanicsUniversity of Science and Technology of China State Key Laboratory of Nonlinear Mechanics Institute of Mechanics Chinese Academy of Sciences

The short-range order and medium-range order of amorphous carbons demonstrated in experiments allow us to rethink whether there exist intrinsic properties hidden by atomic disordering. Here we presented six representative phases of amorphous carbons（0.1–3.4 g/cm3）, namely, disordered graphene network（DGN）, high-density amorphous carbon（HDAC）, amorphous diaphite（a-DG）, amorphous diamond（a-D）, paracrystalline diamond（p-D）, and nano-polycrystalline diamond（NPD）, respectively, classified by their topological features and microstructural characterizations that are comparable with experiments. To achieve a comprehensive physical landscape for amorphous carbons, a phase diagram was plotted in the sp3/sp2versus density plane, in which the counterintuitive discontinuity originates from the inherent difference in topological microstructures, further guiding us to discover a variety of phase transitions among different amorphous carbons. Intriguingly, the power law, log（sp3/sp2） ∝ ρn, hints at intrinsic topology and hidden order in amorphous carbons, providing an insightful perspective to reacquaint atomic disorder in non-crystalline carbons.

Life forms affect beta-diversity patterns of larch forests in China

Plant Diversity 2024年第1期46卷 49-58页

作者： Wenjing fang Qiong Cai Chengjun Ji Jiangling zhu Zhiyao Tang Jingyun fang School of Ecology and Environmental Science Yunnan UniversityKunming 650091China Department of Ecology College of Urban and Environmental Sciencesand Key Laboratory for Earth Surface Processes of the Ministry of EducationPeking UniversityBeijing 100871China

Beta-diversity reflects the spatial changes in community species composition which helps to understand how communities are assembled and biodiversity is formed and maintained. Larch(Larix) forests, which are coniferous forests widely distributed in the mountainous and plateau areas in North and Southwest China, are critical for maintaining the environmental conditions and species diversity. Few studies of larch forests have examined the beta-diversity and its constituent components(species turnover and nestedness-resultant components). Here, we used 483 larch forest plots to determine the total betadiversity and its components in different life forms(i.e., tree, shrub, and herb) of larch forests in China and to evaluate the main drivers that underlie this beta-diversity. We found that total betadiversity of larch forests was mainly dependent on the species turnover component. In all life forms,total beta-diversity and the species turnover component increased with increasing geographic, elevational, current climatic, and paleoclimatic distances. In contrast, the nestedness-resultant component decreased across these same distances. Geographic and environmental factors explained 20%-25% of total beta-diversity, 18%-27% of species turnover component, and 4%-16% of nestedness-resultant component. Larch forest types significantly affected total beta-diversity and species turnover component. Taken together, our results indicate that life forms affect beta-diversity patterns of larch forests in China, and that beta-diversity is driven by both niche differentiation and dispersal limitation. Our findings help to greatly understand the mechanisms of community assemblies of larch forests in China.
