The El Nino-Southern Oscillation(ENSO)has great impacts on the Indian Ocean sea surface temperature(SST).In fact,two major modes of the Indian Ocean SST namely the Indian Ocean Basin(IOB)and the Indian Ocean Dipole(IOD)modes,exerting strong influences on the Indian Ocean rim countries,are both influenced by the ENSO.Based on a combined linear regression method,this study quantifies the ENSO impacts on the IOB and the IOD during ENSO concurrent,developing,and decaying stages.After removing the ENSO impacts,the spring peak of the IOB disappears along with significant decrease in number of events,while the number of events is only slightly reduced and the autumn peak remains for the IOD.By isolating the ENSO impacts during each stage,this study reveals that the leading impacts of ENSO contribute to the IOD development,while the delayed impacts facilitate the IOD phase switch and prompt the IOB development.Besides,the decadal variations of ENSO impacts are various during each stage and over different regions.These imply that merely removing the concurrent ENSO impacts would not be sufficient to investigate intrinsic climate variability of the Indian Ocean,and the present method may be useful to study climate variabilities independent of ENSO.

Journal of Environmental Sciences 2008年第5期20卷 565-570页

Membrane fouling is one of the most important challenges faced in membrane ultrafiltration operations. The copolymers of polysulfone-graft-methyl acrylate were synthesized by homogeneous photo-initiated graft copolymerization. The variables affecting the degree of grafting, such as the time of UV （Ultraviolet-visible） irradiation and the concentrations of the methyl acrylate and photoinitiator, were investigated. The graft copolymer membranes were prepared by the phase inversion method. The chemical and morphological changes were characterized by attenuated total reflection-Fourier transform infrared spectroscopy （ATR/FT-IR）, scanning electron microscopy, and water contact angles measurements. Results revealed that methyl acrylate groups were present on the membranes and the graft degree of methyl acrylate had remarkable effect on the performance of membranes. Pure water contact angle on the membrane surface decreases with the increase of methyl acrylate graft degree, which indicated that the hydrophilicity of graft copolymer membranes was improved. The permeation fluxes of pure water and bovine serum albumin solution were measured to evaluate the antifouling property of graft copolymer membranes, the results of which have shown an enhancement of antifouling property for graft copolymer membranes.

OBJECTIVE:To collect data and investigate the effects of Huangkui capsule(黄葵胶囊,HKC)on chronic kidney disease(CKD).METHODS:PubM ed,Embase,Cochrane Library,and three Chinese databases(China National Knowledge Infrastructure,Wanfang,and China Science and Technology Journal Database)were searched for articles published until October 2020.Randomized controlled trials(RCTs)of HKCs used for treating CKD were reviewed.Data were organized and analyzed using RevMan 5.3 software.RESULTS:HKC significantly lowered the blood urea nitrogen(BUN)level[mean difference(MD)=-2.26;95%confidence interval(CI),-2.91 to-1.61],serum creatinine level(MD=-17.45;95%CI,-22.29 to-12.60),and 24-h urine protein content(MD=-0.73;95%CI,-1.00 to-0.46)and improved the glomerular filtration rate(GFR)(MD=10.69;95%CI,5.57 to 15.81)and serum albumin level(MD=2.20;95%CI,0.49 to 3.90).CONCLUSIONS:Our findings show that HKC could lower the BUN level,serum creatinine level,and 24-h urine protein content.HKC also improved GFR and serum albumin levels.However,high-quality RCTs in other countries with larger sample sizes are warranted to confirm these findings.

High-performance materials are the key to developing new alternative energy-storage systems[1-4].Sodium ion batteries(SIBs)are regarded as the promising large-scale electric energy storage owing to the high abundance and low cost of sodium resources[1,5-9].However,the sluggish kinetics of Na^(+)caused by the large-sized Na^(+)(1.02A)result in the lower energy density and unsatisfactory electrochemical properties[10-14].

Rechargeable Na-CO_(2) Batteries Starting from Cathode of Na2CO_(3) and Carbon Nanotubes

Research 2018年第1期2018卷 2-10页

作者： Jianchao Sun Yong Lu Hao yang Mo Han lianyi Shao Jun Chen Key Laboratory of Advanced Energy Materials Chemistry(Ministry of Education) College of ChemistryNankai UniversityTianjin 300071China

Na-CO_(2) batteries have attracted signifcant attentions due to their high energy density and efective utilization of greenhouse gas CO_(2).However,all reported Na-CO_(2) batteries employ excessive preloaded metal Na,which will lead to safety issues such as dendrite formation and short circuit.In addition,the charging mechanism of reported Na-CO_(2) batteries is not very clear.Here we report the Na-CO_(2) batteries,starting from the cathode of cheap Na2CO_(3) and multiwalled carbon nanotubes(CNTs).Due to the efective electron transfer and high reactivity,the decomposition of Na2CO_(3) and CNTs could take place under 3.8 V.Te charging mechanism of 2Na2CO_(3)+C�→4Na+3CO_(2) without any side reactions is revealed by in/ex situ techniques such as Raman,gas chromatograph,and optical microscope.Dendrite-free Na can quantitatively deposit on the Super P/Al anode because of large specifc surface area and low nucleation barrier of the anode for Na plating.Te batteries could deliver an energy density of 183 Wh kg−1(based on the whole mass of the pouch-type batteries,4 g)with stable cycling performance.Tis work reveals that safe rechargeable Na-CO_(2) batteries could be constructed by cheap Na2CO_(3) and multiwalled carbon nanotubes.

Investigation of the tetraquark states QqQq in the improved chromomagnetic interaction model

In the framework of the improved chromomagnetic interaction model,we complete a systematic study of the S-wave tetraquark states QqQq(Q=c,b,and q=u,d,s)with different quantum numbers:J^(PC)=0^(+(+)),1^(+(±)),and 2^(+(+)).The mass spectra of tetraquark states are predicted,and the possible decay channels are analyzed by considering both the angular momentum and C-parity conservation.The recently observed hidden-charm tetraquark states with strangeness,such as Z_(cs)(3985)^(-),X(3960),and Z_(cs)(4220)^(+),can be well explained in our model.Additionally,according to the wave function of each tetraquark state,we find that the low-lying states of each QqQq configuration have a large overlap to the QQ and qq meson basis,instead of the Qq and qQ meson basis.This indicates that one can search these tetraquark states in future experiments via the channel of QQ and qq mesons.

在文书和微量物证的检验中,经常需要对纸张的种类和同一性进行检验,以便为侦查提供线索,为案件审理提供证据。为建立静电复印纸经济、简便、快速的鉴别方法,优化并确定了纸张的提取条件为沸水(98℃)浴纯净水静止浸泡10 min;对提取物进行了紫外吸收光谱扫描,并对测试数据进行了独立样本T检验。实验结果表明,相同实验条件下,纸张样品提取物的紫外光谱的峰数、峰位、峰形及吸光度值不同。据此,可实现对不同厂家不同品牌、相同厂家不同品牌及相同品牌不同批号静电复印纸的鉴别,为静电复印纸的来源判断及同一性比对提供了新的检验方法。该方法重现性好、操作简单,在一定程度上能够满足于基层检验部门的需要。

综述了近年来SiC基复合材料的裂解碳(PyC)及其衍生物、BN及其衍生物、新型界面相和复合界面相的力学及抗氧化性能改性效果、相关影响因素及不足之处,比较了几类常见的界面相制备工艺。其中,PyC界面相力学改性效果好但抗氧化性差,添加B元素仍难以克服其本征不耐氧化性;BN界面相综合性能佳,但具有中温脆性且不防潮;复合界面相优势众多,但热膨胀系数失配、化学相容性差等问题不可忽视;新型界面相在性能或制备方式上难以兼顾。未来的发展方向为完善性能数据库和损伤机理、探索更多新型界面相类型,以及深入挖掘现有界面相制备工艺的潜力等。
