  • Stressed Lattice Creating New Electric Field for Photoelectrocatalysis
    • Abstract: Abstract To improve the water splitting performance of photoelectrode, Wang’s group borrowed the lithiation mechanism of Li-ion battery to create ordered lattice strain in the electrode. The stressed lattice induced by Li-ion insertion generates a polarized electric field in the bulk, which greatly improves the bulky charge separation and transfer capability and remarkably promotes the photoelectrocatalytic water splitting. This work paves a new avenue for photoelectrochemical water splitting towards efficient solar hydrogen production. The related work was published in Nature Communications on May 1, 2020.

  • La and Sr Composite Oxides-modified Graphite Felt for Aqueous Organic
           Redox Flow Batteries
    • Abstract: Abstract In this study, aqueous organic redox flow batteries(AORFBs) with NaCl as supporting electrolyte were investigated. In AORFBs, the chlorine evolution reaction should be retarded, not the hydrogen evolution reaction. To enhance the catalytic activity of the graphite felt(GF) electrode, the metal oxides were proposed to decorate on the GF surface. Among the loading oxides, significant enhancement of the mass transfer and reaction activity was obtained by the presence of LaSrOx nanoparticles. X-Ray photoelectron spectroscopy and contact angle measurements revealed that the content of oxygen-containing groups and the hydrophilicity were remarkably increased. After the electrode assembled in the battery, the LaSrOx/GF electrode presented huge enhancement of the battery performance, obviously increasing in the battery capacity and efficiency. At a current of 50 Am/cm2, the energy efficiency(EE) of the battery increased from 54.76% to 61.37% by the LaSrOx/GF electrode. Furthermore, the cyclability of the system tested that no obviously fading was observed after 100 cycles, signifying the excellent stability of the LaSrOx/GF electrode.

  • Synthesis of Caffeic Acid Sulphonamide Derivatives and Preliminary
           Exploration of Their Biological Applications
    • Abstract: Abstract Structural modification of native compounds is an effective way to develop new drugs with increased pharmacological activities and improved material characteristics. In this study, caffeic acid sulphonamide deriva-tives(CSs) were synthesised by conjugating sulphonamides to the backbone of caffeic acid. The structures of these derivatives were elucidated by means of Fourier transform infrared spectroscopy(FTIR), 1H NMR, 13C NMR, and electrospray ionization mass spectroscopy(ESI-MS). A content determination method was established by ultraviolet detection. The lipophilicity, 2,2-diphenyl-1-picrylhydrazy free radical(DPPH) scavenging capacity, anti-coagulant effects, anti-bacterial activity, cytotoxicity, in vitro anti-pro liferative activity against tumour cells, and the ability of the compounds to promote the proliferation of chondrocytes were evaluated. The results indicate that CSs exhibit strong DPPH scavenging activity, high lipophilicity, good anti-coagulant activities, wide anti-bacterial activity range, low cytotoxicity, and an excellent ability to promote chondrocyte proliferation.

  • Assembly of Three Scandium-containing Heteropolytungstates Based on a
           Building-block Synthetic Strategy
    • Abstract: Abstract Three novel scandium-containing heteropolytungstates [Sc3(H2O)3NO3(PW9O34)2]10−(1a), [Sc8(H2O)2(GeW9O34)2(GeW6O26)2]12−(2a) and [Sc11(W6O10)2(OH)2(H2O)16(BiW9O33)6]27−(3a) were synthesized by reactions of ScIII ions with trilacunary Keggin precursors, [A-α-XW9O34]in−(X=P, Ge, in=9, 10) or [B-α-BiW9O33]9−, in NaOAc/HOAc buffer solution under conventional synthetic condition, respectively. All the three compounds were characterized by means of single-crystal X-ray diffraction(XRD), Fourier transform-infrared(FTIR) spectroscopy ul-traviolet-visible(UV-Vis) spectroscopy, elemental analysis, and thermogravimetric analysis. The aqueous solution stability of the sandwich polyanion [Sc3(H2O)3NO3(PW9O34)2]10− was also verified by electrospray ionization mass spectrometry(ESI-MS) due to its good solubility in water.

  • Synergistic Effects of External Electric Field and Solvent Vapor Annealing
           with Different Polarities to Enhance β -Phase and Carrier Mobility of the
           Poly(9,9-dioctylfluorene) Films
    • Abstract: Abstract In this work, the synergistic effects of external electric field(EEF) and solvent vapor annealing to enhance β-phase and carrier mobility of poly(9,9-dioctylfluorene)(PFO) films were investigated. It is found that EEF can promote the PFO β-phase conformation transition and orientate the PFO chains along the EEF direction with the assistance of polar solvent vapor annealing. PFO chain orderness is closely related to the solvent polarity. In particular, the β-phase content in the annealed film of strong polar chloroform vapor increases from 18.7% to 34.9% after EEF treatment. Meanwhile a characteristic needle-like crystal is formed in the film, as a result, the hole mobility is enhanced by an order of magnitude. The mechanism can be attributed to the fast polarization of solvent dipole under the action of EEF, thus forming a driving force that greatly facilitates the orientation of PFO dipole unit. Research also reveals that EEF driving of the PFO chains does not occur with an insoluble solvent vapor since the solvent molecules cannot swell the film, thus there is insufficient free volume for PFO chains to adjust their conformation. This research enriches the understanding of the relationship between solvent vapor annealing and EEF in orientation polymers, and this method is simple and controlled, and capable of integrating into large-area thin film process, which provides new insights to manufacture low-cost and highly ordered polymer films, and is of great significance to enhance carrier mobility and efficiency of photoelectric devices based on polymer condensed matter physics.

  • Precise Functionalization of Remote C-H Bonds
    • Abstract: Abstract Remote C-H bond functionalization of arenes with precise control is a recognized extraordinary challenge in organic synthesis. Recently, Yu and Houk et al. developed an elegant strategy to distinguish and functionalize remote Csp2-H bonds of (hetero)arenes within one-bond distance by the interplay of a remote directing template and a transient norbornene-type mediator. A wide range of medicinally important benzoazines are well compatible with this method. The chemistry significantly expands the toolbox for site-selective functionalization of remote Csp2-H bond of (hetero)arenes. This work has been published in Nature Chemistry in March, 2020.

  • Li Ion Exchanged α -MnO 2 Nanowires as Efficient Catalysts for Li-O 2
           Batteries
    • Abstract: Abstract Due to the limited energy densities, which could be achieved by lithium-ion cells, Li-O2 batteries, which could provide a promising super energy storage medium, attract much attention nowadays. For its high activity, high storage and low cost, Mn-based oxides have shown versatile application in various batteries. To enhance the cyclability of Li-O2 batteries, here, we synthesized a kind of α-MnO2 nanowires as a bifunctional catalyst for Li-O2 batteries. The particular structure of α-MnO2 reduces the mass transfer resistance of the battery, and the MnO2 nanowires were ion exchanged by saturated lithium sulfate solution so as to further improve the performance of the catalyst. The exchanged α-MnO2 catalyst showed a high discharge specific capacity(6243 mA·h/g at a current density of 200 mA/g) and significantly improved the cyclability up to the 55th cycle(200 mA/g with capacity of 1000 mA·h/g). The results show that the Li ion exchange method is a promising strategy for improving the performance of MnO2 catalyst for Li-O2 batteries.

  • Controllable Preparation of Plasmonic Gold Nanostars for Enhanced
           Photothermal and SERS Effects
    • Abstract: Abstract Gold nanostars(Au NSs) are asymmetric anisotropic nanomaterials with sharp edge structure. As a promising branched nanomaterial, Au NS has excellent plasmonic absorption and scattering properties. In order to tune the plasmonic photothermal and surface-enhanced Raman scattering(SERS) activity of Au NSs to obtain the desired characteristics, the effects of reagents on the local surface plasmon resonance(LSPR) bands of Au NSs were studied and the morphology and size were regulated. Nanoparticles with different sharp edges were synthesized to make their local plasmon resonance mode tunable in the visible and near-infrared region. The effects of the number and sharpness of different tips under the control of AgNO3 on the photothermal response of Au NSs and the SERS activity and their mechanism were discussed in detail. The results show that as the length of the branch tip becomes longer and the sharpness increases, the plasmonic photothermal effect of Au NSs is strengthened, and the photothermal conversion efficiency is the highest up to 40% when the length of Au NSs is the longest. Au NSs with high SERS activity are used for the Raman detection substrate. Based on this property, the quantitative detection of the pesticide thiram is achieved.

  • Single and Binary Dye Adsorption of Methylene Blue and Methyl Orange in
           Alcohol Aqueous Solution via Rice Husk Based Activated Carbon: Kinetics
           and Equilibrium Studies
    • Abstract: Abstract The present work was mainly focused on the single and binary adsorption of methylene blue(MB) and methyl orange(MO) from alcohol aqueous solution over rice husk based activated carbon(RHAC). The study of single dye adsorption equilibrium experiments found that the Langmuir adsorption model was consistent with the adsorption behavior of RHAC on MB and MO, indicating that it was a single layer adsorption. The adsorption behavior conformed to the pseudo-second-order kinetic model. The binary dye adsorption experiments showed that the Langmuir-Freundlich model could be applied to describe the adsorption behavior of RHAC on MB and MO. Comparation with the single dye system, the adsorption capacity on the binary dye system was larger, and there was “competitive adsorption” and “synergistic adsorption” effects existed. Meanwhile, the pseudo-second-order kinetic model also fit for the binary dye adsorption behavior.

  • Unveiling the Hidden Movements in the Shuttling of Rotaxanes
    • Abstract: Abstract Movements in molecular machines are usually diverse and coupled, but some of them are often implicit and hard to be observed in experiments. In the present work, the two- or three-dimensional free-energy landscapes characterizing the coupled shuttling and other movements of a series of pH-triggered rotaxanes composed of a crown ether and an H-shaped axle with distinct number of phenyl rings(n=1–3) have been explored. The results show that although the calculated free-energy barriers against shuttling in the rotaxanes(n=2 and 3) change slightly, the movements coupled with the shuttling vary significantly with the axle length. At high pH, the shuttling in the rotaxane of n=2 is coupled with the isomerization of the wheel, while the shuttling in the one of n=3 is accompanied by both the isomerization and the rotation of the macrocycle. In addition, the crown ether underwent greater conformational change during shuttling at low pH compared to that at high pH. These results indicate that disentangling the coupled movements is important to reveal the underlying molecular mechanism of the shuttling.

  • Fabrication of ZnS/CdS Heterojunction by Using Bimetallic MOFs Template
           for Photocatalytic Hydrogen Generation
    • Abstract: Abstract A new ZnS/CdS heterojunction is constructed through the direct sulfurization of a metal ions exchanged Zn/Cd-MOF precursor(MOF=metal-organic framework material). The composition, structure, morphology, photoabsorption and photoelectric performance of the ZnS/CdS are characterized by powder X-ray diffraction(PXRD), scanning electron microscope(SEM), transmission electron microscope(TEM), diffuse reflection spectrum(DRS), photoelectric current(PEC), electrochemical impedance spectroscopy(EIS) and photoluminescence(PL) technologies. Since the metal ions are highly orderly separated by the organic ligands and the inherent porosity of the Zn/Cd-MOF, the as-synthesized ZnS/CdS possesses a large surface area and intimate contact at the heterogeneous interface with uniform ZnS/CdS nanoparticles. The photocatalytic hydrogen evolution activity of the ZnS/CdS is investigated under visible light irradiation(λ⩾420 nm). It exhibits enhanced photocatalytic performance that the optimal ZnS/CdS achieves a maximum average hydrogen production rate of 2348 µmol·h−1·g−1. A possible electron transfer mechanism is therefore proposed by the analyses of the Mott-Schottky plots.

  • A Big Jump in Nacre-inspired Strong, Tough Composites
    • Abstract: Abstract To achieve structural order and strength-toughness balance similar to natural composites like nacre has been highly challenging, especially in a practically viable manner. Liu et al. developed a continuous preparation method to construct such high performance composites through a superspreading strategy at the oil/water/hydrogel interface. Exploiting the strong shear force at the interface, nanoparticles, such as nanosheets and nanotubes oriented and stacked together rapidly(as short as 358 ms) and the composites revealed the tensile strength and fracture toughness far higher those of natural nacre(9.0 and 20.4 times higher). This work has been published in Nature, 2020.

  • Regioselective Magneto-optical Heteronanorods Enabling Chiroptical
           Activity
    • Abstract: Abstract Synthesis of colloidal heterostructures with rational design and controllable precision represents a promising strategy for achieving novel properties and applications. Most recently, Zhuang et al. reported a “double-buffer-layer engineering” concept that was capable of regioselectively growing magnetic Fe3O4 nanodomains only at single ends of semiconductor ZnxCd1−xS(0⩽x⩽1) nanorods. The resulting composite nanostructures exhibited chiroptical activity due to the local magnetic fields introduced by regiospecific magnetic nanodomains, highlighting the promise of controlled colloidal chemistry in synthesizing chiroptical nanostructures in the absence of chiral molecules and helical geometries. The work has been published online in Nature Nanotechnology on January 20, 2020.

  • Bubble Consumption Dynamics in Electrochemical Oxygen Reduction
    • Abstract: Abstract Electrochemical oxygen reduction reaction(ORR) is crucial for fuel cells and metal-air batteries, while the oxygen consumption dynamics study during ORR, which affects the ORR efficiency, is not as concerned as catalysts design does. Herein the consumption behavior of an individual oxygen bubble on Pt foils with different wettabilities during ORR was tracked by a real-time approach to reveal whether the surface wettability of electrode can influence the consumption dynamics and determine the reaction reactive zones of oxygen bubble consumption. The oxygen bubble underwent a “constant contact angle” dominant consumption model on aerophobic Pt foil, while an initial “constant radius” and the subsequent “constant contact angle” oxygen consumption models were observed on aero-philic Pt foil. Results here demonstrated that the current was proportional to the bottom contact area, rather than the three-phase contact line of the bubbles according to the fitting curves between individual bubble current and the con-sumption behavior parameters. This study highlights the important role of the gas-solid interface in influencing the efficiency of gas consumption electrochemical reactions, which shall benefit the understanding of reaction kinetics and the rational design of electrocatalysts.

Herein, Fe single atoms anchored on nanosheet-linked, defect-rich, highly N-doped 3D porous carbon(Fe-SAs/NLPC) electrocatalysts were obtained by pyrolyzing salt-sealed Fe-doped zeolitic imidazolate frameworks(ZIFs). NaCl functions both as pore-forming agent and closed nanoreactor, which can not only lead to the formation of defects-rich three-dimensional interconnected structures with high N-doping content to expose abundant active sites, promote mass transfer and electron transfer, but also facilitate the effective incorporation of Fe to form Fe-Nx active sites without aggregation. These unique characteristics render Fe-SAs/NLPC outstanding electrocatalytic activity for ORR, with one-set potential of 0.96 V and high kinetic current density(jK) of 33.32 mA/cm2 in alkaline medium, which surpass the values of most nonprecious-metal catalysts and even commercial Pt/C.

  • Semitransparent Flexible Organic Solar Cells
    • Abstract: Abstract Abstract The semitransparent flexible organic solar cell takes advantages of flexibility, transparency, color adjustment property, which is more conducive to integrate on buildings and mobile terminals. Ascribing to the developments of narrow band gap donors and the new non-fullerene acceptors, the power conversion efficiency of semitransparent flexible organic solar cells has been achieved 10% to 12% with average visible transmittance of 17% to 21%. This review summarizes the molecular design of the most representative active layer materials, and discusses the characterization of semitransparent parameters paradigms, then we discuss how to optimize the device in combination with optical simulation, and finally list the recent development of semitransparent flexible electrodes of ITO-free organic solar cells, and give our perspectives on the next step direction.

  • Bimetallic Sulfide/Sulfur Doped T 3 C 2 T x MXene Nanocomposites as
           High-performance Anode Materials for Sodium-ion Batteries
    • Abstract: Abstract The application of transition metal dichalcogenides(TMDs) as anode materials in sodium-ion batteries (SIBs) has been hindered by low conductivity and poor cyclability. Herein, we report the synthesis of CoxFe1−xS2 bimetallic sulfide/sulfur-doped Ti3C2 MXene nanocomposites(CoxFe1−xS2@S-Ti3C2) by a facile co-precipitation process and thermal-sulfurization reaction. The interconnected 3D frameworks consisting of MXene nanosheets can effectively buffer the volume change and enhance the charge transfer. In particular, sulfur-doped MXene nanosheets provide rich active sites for sodium storage and restrain sulfur loss during charging/discharging processes, leading the increase of specific capacity and cycling the stability of anode materials. As a result, CoxFe1−xS2@S-Ti3C2 anodes exhibited high capacity, high rate capability and long cycle life(399 m·Ah/g at 5 A/g with an 94% capacity retention after 600 cycles).

  • Garnet-type Solid-state Electrolyte Li 7 La 3 Zr 2 O 12 : Crystal
           Structure, Element Doping and Interface Strategies for Solid-state Lithium
           Batteries
    • Abstract: Abstract The continuous development of solid-state electrolytes(SSEs) has stimulated immense progress in the development of all-solid-state batteries(ASSBs). Particularly, garnet-typed SSEs in formula of Li7La3Zr2O12(LLZO) are fctivity(<1 mS/cm), wide electrochemical window(<5 V), and good chemical electrochemical stability for lithium, which are critical factors to ensure a stable, and high performance ASSBs. This review will focus on the challenges related to LLZOs-based electrolyte, and update the recent developments in structural design of LLZOs, which are discussed in three major sections: (i) crystal structure and the lithium-ion transport mechanism of LLZO; (ii) single-site and multi-site doping of Li sites, La sites and Zr sites to enhance Li ions conductivity(LIC) and stability of LLZO; (iii) interface strategies between electrodes and LLZO to decrease interface area-specific resistance(ASR).

  • Advanced Current Collectors for Alkali Metal Anodes
    • Abstract: Abstract High-energy-density batteries are in urgent need to solve the ever-increasing energy storage demand for portable electronic devices, electric vehicles, and renewable solar and wind energy systems. Alkali metals, typically lithium(Li), sodium(Na) and potassium(K), are considered as the promising anode materials owing to their low electrochemical potential, low density, and high theoretical gravimetric capacities. However, the problem of dendrite growth of alkali metals during their plating/stripping process will lead to low Coulombic efficiencies, a short lifespan and huge volume expansion, eventually hindering their practical commercialization. To resolve this issue, a very effective approach is engineering the anodes on structured current collectors. This review summarizes the development of the alkali metal batteries and discusses the recent advances in rational design of anode current collectors. First, the challenges and strategies of suppressing alkali-metal dendrite growth are presented. Then the special attention is paid to the novel current collector design for dendrite-free alkali metal anodes. Finally, we give conclusions and perspective on the current challenges and future research directions toward advanced anode current collectors for alkali metal batteries.
