Characterization methods of organic electrode materials

The development of novel organic electrode materials is of great significance for improving the reversible capacity and cycle stability of rechargeable batteries. Before practical application,it is essential to characterize the electrode materials to study their structures,redox mechanisms and electrochemical performances. In this review,the common characterization methods that have been adopted so far are summarized from two aspects: experimental characterization and theoretical calculation. The experimental characterization is introduced in detail from structural characterization,electrochemical characterization and electrode reaction characterization. The experimental purposes and working principles of various experimental characterization methods are briefly illustrated. As the auxiliary means,theoretical calculation provides the theoretical basis for characterizing the electrochemical reaction mechanism of organic electrode materials. Through these characterizations,wewill have a deep understanding about the material structures,electrochemical redox mechanisms,electrochemical properties and the relationships of structure- property. It is hoped that this review would help researchers to select the suitable characterization methods to analyze the structures and performances of organic electrode materials quickly and effectively.
Thin buffer layer assist carbon-modifying separator for long-life lithium metal anodes

The guided Li dendrite growth by carbon-modifying separator is believed to be an effective strategy for enhancing life of lithium metal batteries (LMBs). However,the weak adhesions,as well as the large interface impedance between the smooth separator and the carbon functional layer (CFL) lead to an easily peeling of the CFL after repetitive cycles. Herein,we propose a promising solution by an inserting thin buffer layer (TBL) to strengthen the adhesion between CFL and separator as a double modifying layer (C-TBL) of the LMBs separator,which greatly improves the stability of the CFL and provides an effective Li metal anode protection. Owing to the sufficient ionic conductivity,chemical stability and strong adhesion to the separator of the TBL,it can avoid the failure of the CFL functionality with small interface impedance. Moreover,the CFL effectively reduces localized flux of Li~+ through its abundant pores. The Li/Li cell with C-TBL separator displays the Li dendrite-free and stable cycling performance for at least 1500 h. When LiFePO_4 (LFP) is employed as the cathode electrode,the assembled full cell with C-TBL separator shows the excellent rate performance and outstanding cycling capability. Our study builds a stable Li~+ conducting "bridge" between the functional layer and the separator in stabilizing Li metal anode,and provides a fresh idea of the artificial separator of LMBs.
Semi-blind compressed sensing via adaptive dictionary learning and one-pass online extension

Compressed sensing (CS),as an efficient data acquisition paradigm,has attracted much attentions since it came up.The fundamental principle of CS is that a signal,which is sparse under some sparsity basis,can be efficiently acquired and accurately recovered via far fewer measurements than the traditional Shannon-Nyquist sampling.Since the number of measurements is much smaller than the number of signal coefficients,there potentially exist multiple solutions for the unknown signal,leading to so-called illposedness.To solve this problem,CS adopts a common mechanism that regularizes the recovery problem by constraining the original signal to be sparse under some sparsity basis.Thus,the prior knowledge about the sparsity basis is critical for CS recovery.The often-used sparsity bases include the discrete cosine transform (DCT) and discrete wavelet transform (DWT).Although CS achieves high efficiency under these sparsity bases,these sparsity bases are data-independent,thus not optimal for CS recovery at hand.
Semi-supervised local feature selection for data classification

Conventional feature selection methods select the same feature subset for all classes,which means that the selected features might work better for some classes than the others.Towards this end,this paper proposes a new semi-supervised local feature selection method (S2LFS) allowing to select different feature subsets for different classes.According to this method,class-specific feature subsets are selected by learning the importance of features considering each class separately.In particular,the class labels of all available data are jointly learned under a consistent constraint over the labeled data,which enables the proposed method to select the most discriminative features.Experiments on six data sets demonstrate the effectiveness of the proposed method compared to some popular feature selection methods.
A variable-period scheme for dynamic sampled-data stabilization

With the popularity of computers and networks in control systems,sampled-data control is becoming increasingly important and has attracted intensive attention over the past decades.However,for systems with serious uncertainties(without any known upper bounds),particularly additive uncertainties,it is rather challenging to achieve sampled-data control:the classical schemes with constant sampling rate usually fail to work,while schemes with variable sampling rate are complex and difficult to implement.We specially mention,wherein an adaptive adjustment mechanism was introduced to the variable sampling rate to handle the serious uncertainties.However,the scheme in is inapplicable to cases with additive uncertainties/disturbances.Although studies in considered cases with additive disturbances,these authors provided only sampled-data control schemes without any compensation mechanism to additive disturbances.Thus,they established only certain quantitative relations between the system states and the additive disturbances (e.g.,input-to-state stability in and L_p in).In a separate development,proposed an event-triggered scheme of output regulation for single-input single-output linear systems.

Impact of changes in precipitation pattern on food supply in a monsoon interlacing area and its mechanism:A case study of Yunnan Province

Following climate change,changes in precipitation patterns and food security are major challenges faced by humans.However,research on how these changes in precipitation pattern impacts food supply is limited.This study aims to elucidate this impact and response mechanisms using precipitation data of a climate change-sensitive confluence zone of the southwest and southeast monsoons in Yunnan Province from 1988 to 2018.The results revealed that the precipitation pattern could be divided into three periods:abundant precipitation(Stage I,from 1988 to 2004),decreased precipitation(Stage II,from 2005 to 2015),and drought recovery(Stage III,from 2016 to 2018).Following the transition from Stage I to Stage II and from Stage II to Stage III,the area of precipitation changed significantly,accounting for 15.07%,13.87%,and 16.53% of Yunnan's total area,for Stages I,II,and III,respectively.At the provincial level,a significant positive correlation was observed between precipitation and food production(r = 0.535,P <0.01),and the correlation coefficient between precipitation and grain yield was higher than that between precipitation and meat and milk production.Based on a precipitation-grain yield transect and breakpoint detection method,key precipitation thresholds affecting grain yield were estimated as 700 and 1500 mm,respectively;when precipitation was <700,700-1500,and ≥1500 mm,the correlation coefficients between precipitation and grain yield were 0.448(P <0.01),0.370(P <0.01),and -0.229(P >0.05),respectively.Based on the precipitation thresholds,Yunnan Province can be divided into precipitation surplus,precipitation equilibrium,and precipitation deficit regions,corresponding countermeasures to stabilize grain yield were proposed for each of these regions.The threshold effect of precipitation on grain yield is controlled by molecular-level water-crop mechanisms,in which reactive oxygen species,a by-product of plant aerobic metabolism,plays a key regulatory role.

铑催化区域和对映选择性外消旋1,2-二取代烯丙基磷酸酯烯丙基胺化反应

过渡金属催化的烯丙基胺化反应是构建碳氮键的有效方法之一.目前,化学家们广泛而深入地研究了单取代烯丙基底物的区域和对映选择性亲核取代反应,报道了使用多种过渡金属配合物的催化模式.然而对于1-位和2-位同时有取代基的烯丙基底物,实现其高效立体选择性烯丙基取代反应仍有很大的挑战性,这是由于:(1)金属氧化加成后生成的中间体为η3配位的1,2-二取代π-烯丙基金属配合物,由于R1和R2之间排斥作用,存在能量比较接近的syn和anti两种构型,影响反应的选择性和活性(Scheme 1, a);(2)直链二取代烯丙基底物反应活性低,不利于底物转化,若采用活性较高的支链二取代烯丙基底物,则要解决动力学拆分带来新的挑战.迄今为止,文献中仅报道了一例使用2-甲基-1,2-二取代烯丙基底物的烯丙基烷基化反应.随着2-位取代基位阻的变化,反应难度进一步增大.因此,发展新的催化体系,解决此类反应中的立体选择性和活性等挑战性问题,具有重要的意义.

Quantum-limited localization and resolution in three dimensions

As a method to extract information from optical systems, imaging can be viewed as a parameter estimation problem.The fundamental precision in locating one emitter or estimating the separation between two incoherent emitters is bounded below by the multiparameter quantum Cramer-Rao bound(QCRB).Multiparameter QCRB gives an intrinsic bound in parameter estimation.We determine the ultimate potential of quantum-limited imaging for improving the resolution of a far-field, diffraction-limited optical field within the paraxial approximation.We show that the quantum Fisher information matrix(QFIm)in about one emitter's position is independent on its true value.We calculate the QFIm of two unequal-brightness emitters' relative positions and intensities;the results show that only when the relative intensity and centroids of two-point sources, including longitudinal and transverse directions, are known exactly, the separation in different directions can be estimated simultaneously with finite precision.Our results give the upper bounds on certain far-field imaging technology and will find wide use in applications from microscopy to astrometry.
Do age-related macular degeneration genes show association with keratoconus?

Background: Keratoconus (KC) is a common corneal condition with an unknown gender predominance. Although numerous studies have investigated the genetic component of KC, no specific genes have yet been attributed to the condition. We recently reported posterior segment changes occurring in the eyes of KC patients. However, it is not clear whether these changes are part of KC pathogenesis or reflect changes in anatomical features of the eye manifested by changes at the cornea. Given retinal changes represent the main characteristics observed in age-related macular degeneration (AMD) and that pleiotropy has been demonstrated between different eye diseases, we wished to assess if known AMD associated genes were also associated with KC. Methods: A total of 248 KC subjects and 366 non-KC (control) subjects were recruited from public and private clinics in Melbourne for this analysis. Nineteen single nucleotide polymorphisms (SNPs) previously associated with AMD, including rs10490924 (ARMS2/HTRA1), rs10737680 (CFH), rs13278062 (TNFRSF10A), rs1864163 (CETP), rs2230199 (C3), rs3130783 (IER3/DDR1), rs334353 (TGFBR1), rs3812111 (COL10A1), rs429608 (C2/CFB), rs4420638 (APOE), rs4698775 (CFD, rs5749482 (TIMP3), rs6795735 (ADAMTS9), rs8017304 (RAD51B), rs8135665 (SLC16A8), rs920915 (LIPC), rs943080 (VEGFA), rs9542236 (B3GALTL) and rs13081855 (COL8A1/FILIP1L), were genotyped in this cohort. Logistic regression was applied to evaluate the association between these SNPs and KC on both genders together, as well as each gender separately. Linear regression was also applied to assess the association between SNPs and corneal curvature. Bonferroni correction was applied to adjust for multiple testing. Results: Genotyping data were available for 18 SNPs. The SNP, rs6795735 (ADAMTS9) was significantly associated with KC (P = 3.5 × 10~(-4)) when both genders were assessed, whereas rs5749482 (TIMP3) was only associated in males (P = 7.7 × 10~(-4)) following Bonferroni multiple correction. However, when the covariates of age and gender were included, the associations became non-significant. In addition, none of the SNPs appeared significant for corneal curvature. Conclusions: Our study suggested a potential association of rs6795735 in the ADAMTS9 gene and rs5749482 in the TIMP3 gene in KC and that different associations may be gender specific. Overall, SNPs initially identified as associated with AMD following multiple correction may be further impacted by other factors such as age or gender and further studies are needed to resolve this issue.
Electrolyte/Structure-Dependent Cocktail Mediation Enabling High-Rate/Low-Plateau Metal Sulfide Anodes for Sodium Storage

As promising anodes for sodium-ion batteries, metal sulfides ubiquitously suffer from low-rate and high-plateau issues, greatly hindering their application in full-cells.Herein, exemplifying carbon nanotubes(CNTs)-stringed metal sulfides superstructure(CSC)assembled by nano-dispersed SnS_2 and CoS_2 phases, cocktail mediation effect similar to that of high-entropy materials is initially studied in ether-based electrolyte to solve the challenges.The high nano-dispersity of metal sulfides in CSC anode underlies the cocktail-like mediation effect, enabling the circumvention of intrinsic drawbacks of different metal sulfides.By utilizing ether-based electrolyte, the reversibility of metal sulfides is greatly improved, sustaining a long-life effectivity of cocktail-like mediation.As such, CSC effectively overcomes low-rate flaw of SnS_2 and highplateau demerit of CoS_2,simultaneously realizes a high rate and a low plateau.In half-cells, CSC delivers an ultrahigh-rate capability of 327.6 mAh g~(-1) anode at 20 A g~(-1), far outperforming those of monometallic sulfides(SnS_2, CoS_2)and their mixtures.Compared with CoS_2 phase and SnS_2/ CoS_2 mixture, CSC shows remarkably lowered average charge voltage up to ca.0.62 V.As-assembled CSC//Na1.5VPO_4.8F0.7 full-cell shows a good rate capability(0.05 ~ 1.0 A g~(-1), 120.3 mAh g~(-1) electrode at 0.05 A g~(-1))and a high average discharge voltage up to 2.57 V, comparable to full-cells with alloy-type anodes.Kinetics analysis verifies that the cocktail-like mediation effect largely boosts the charge transfer and ionic diffusion in CSC, compared with single phase and mixed phases.Further mechanism study reveals that alternative and complementary electrochemical processes between nano-dispersed SnS_2 and CoS_2 phases are responsible for the lowered charge voltage of CSC.This electrolyte/ structure-dependent cocktail-like mediation effect effectively enhances the practicability of metal sulfide anodes, which will boost the development of high-rate/-voltage sodium-ion full batteries.
Oxygen-Defect Enhanced Anion Adsorption Energy Toward Super-Rate and Durable Cathode for Ni-Zn Batteries

The alkaline zinc-based batteries with high energy density are becoming a research hotspot.However, the poor cycle stability and low-rate performance limit their wide application.Herein, ultra-thin CoNiO_2 nanosheet with rich oxygen defects anchored on the vertically arranged Ni nanotube arrays(Od-CNO@Ni NTs)is used as a positive material for rechargeable alkaline Ni-Zn batteries.As the highly uniform Ni nanotube arrays provide a fast electron/ion transport path and abundant active sites, the Od-CNO@Ni NTs electrode delivers excellent capacity(432.7 mAh g~(-1))and rate capability(218.3 mAh g~(-1)at 60 A g~(-1)).Moreover, our Od-CNO@Ni NTs//Zn battery is capable of an ultra-long lifespan(93.0% of initial capacity after 5000 cycles), extremely high energy density of 547.5 Wh kg~(-1)and power density of 92.9 kW kg~(-1)(based on the mass of cathode active substance).Meanwhile, the theoretical calculations reveal that the oxygen defects can enhance the interaction between electrode surface and electrolyte ions, contributing to higher capacity.This work opens a reasonable idea for the development of ultra-durable, ultra-fast, and high-energy Ni-Zn battery.
All-Climate Aluminum-Ion Batteries Based on Binder-Free MOF-Derived FeS_2@C/CNT Cathode

Aluminum-ion batteries(AIBs)are promising next-generation batteries systems because of their features of low cost and abundant aluminum resource.However,the inferior rate capacity and poor all-climate performance,especially the decayed capacity under low temperature,are still critical challenges toward high-specific-capacity AIBs.Herein,we report a binder-free and freestanding metal-organic framework-derived FeS_2@C/carbon nanotube(FeS_2@C/CNT)as a novel all-climate cathode in AIBs working under a wide temperature window between –25 and 50 °C with exceptional flexibility.The resultant cathode not only drastically suppresses the side reaction and volumetric expansion with high capacity and long-term stability but also greatly enhances the kinetic process in AIBs with remarkable rate capacity(above 151 mAh g~(-1) at 2 A g~(-1))at room temperature.More importantly,to break the bottleneck of the inherently low capacity in graphitic material-based all-climate AIBs,the new hierarchical conductive composite FeS_2@C/CNT highly promotes the all-climate performance and delivers as high as 117 mAh g~(-1) capacity even under –25 °C.The well-designed metal sulfide electrode with remarkable performance paves a new way toward all-climate and flexible AIBs.
A Universal Atomic Substitution Conversion Strategy Towards Synthesis of Large-Size Ultrathin Nonlayered Two-Dimensional Materials

Nonlayered two-dimensional(2D)materials have attracted increasing attention, due to novel physical properties, unique surface structure,and high compatibility with microfabrication technique.However, owing to the inherent strong covalent bonds, the direct synthesis of 2D planar structure from nonlayered materials, especially for the realization of large-size ultrathin 2D nonlayered materials, is still a huge challenge.Here, a general atomic substitution conversion strategy is proposed to synthesize large-size, ultrathin nonlayered 2D materials.Taking nonlayered CdS as a typical example, large-size ultrathin nonlayered CdS single-crystalline flakes are successfully achieved via a facile low-temperature chemical sulfurization method, where pre-grown layered CdI_2 flakes are employed as the precursor via a simple hot plate assisted vertical vapor deposition method.The size and thickness of CdS flakes can be controlled by the CdI_2 precursor.The growth mechanism is ascribed to the chemical substitution reaction from I to S atoms between CdI_2 and CdS,which has been evidenced by experiments and theoretical calculations.The atomic substitution conversion strategy demonstrates that the existing 2D layered materials can serve as the precursor for difficult-to-synthesize nonlayered 2D materials, providing a bridge between layered and nonlayered materials, meanwhile realizing the fabrication of large-size ultrathin nonlayered 2D materials.
Integration of association and computational methods reveals functional variants of LEPR gene for abdominal fat content in chickens

Leptin receptor (LEPR) plays a vital role in obesity in humans and animals. The objective of this study is to assess LEPR functional variants for chicken adipose deposition by integration of association and in-silico analysis using a unique chicken population, the Northeast Agricultural University broiler lines divergently selected for abdominal fat content (NEAUHLF). Five online bioinformatics tools were used to predict the functionality of the single nucleotide polymorphisms (SNPs) in coding region. Further, the possible structure–function relationship of high confidence SNPs was determined by bioinformatics analyses, including the conservation and stability analysis based on amino acid residues, prediction of protein ligand-binding sites, and the superposition of protein tertiary structure. Meanwhile, we analyzed the association between abdominal fat traits and 20 polymorphisms of chicken LEPR gene. The integrated results showed that rs731962924 (N867I) and rs13684622 (C1002R) could lead to striking changes in the structure and function of proteins, of which rs13684622 (C1002R) was significantly associated with abdominal fat weight (AFW, P=0.0413) and abdominal fat percentage (AFP, P=0.0260) in chickens. Therefore, we are of the opinion that rs13684622 (C1002R) may be an essential functional SNP affecting chicken abdominal fat deposition, and potentially applied to improvement of broiler abdominal fat in molecular marker-assisted selection (MAS) program. Additionally, the coupling of association with computer electronic predictive analysis provides a new avenue to identify important molecular markers for breeders.
