  • pH-Responsive Reversible DNA Self-assembly Mediated by Zwitterion
    • Abstract: Abstract pH-Responsive DNA assembles have drawn growing attentions owing to their great potential in diverse areas. However, pH-responsive motifs are limited to specific DNA sequences and annealing is usually needed for DNA assemblies; therefore, sequence-independent pH-responsive DNA assembly at room temperature is highly desired as a more general way. Here, we propose a reversible pH-responsive DNA assembly strategy at room-temperature using zwitterion, glycine betaine(GB), as charge-regulation molecules. The reversible assembly and disassembly of DNA nanostructures could be achieved by alternatively regulating the acidic and basic environments in the presence of GB, respectively. In an acidic environment, carboxylate group in GB was protonated and GB was positively charged, which facilitated to shield the inherent electrostatic repulsion of DNA strands. Molecular simulation showed that the newly formed carboxyl group in protonated GB could form hydrogen bonds with bases in DNA to promote the assembly of DNA strands. In a basic solution, carboxylate group in GB was deprotonated and GB was neutral, thus inducing the dissociation of DNA assembly.

  • Preparation and Characterization of CaO/ZnO Core-shell Structured
           Nanoparticles
    • Abstract: Abstract Residual bacteria and microleakage in a complicated root canal can often result in reinfection of the periapical tissues. To promote the antibacterial and sealing effects of a root canal filling, core-shell structured CaO/ZnO nanospheres were synthesized using a precipitation method based on a traditional root canal sealer, zinc oxide-eugenol(ZOE). The obtained CaO/ZnO particles had a size of 80–90 nm and a core-shell structure. The film thickness, flow rate, pH, and calcium ion release of the core-shell structured CaO/ZnO nanospheres-eugenol paste were tested. The pH and calcium ion release results showed a slight increase in the prepared nanospheres, with a flow rate of 24.22 mm and a formed film thickness of 30 µm, which are basically consistent with ISO 6876:2001 standards(regarding dental root canal sealing materials). Cytotoxicity tests showed that the cytocompatibility of the CaO/ZnO nanospheres-eugenol paste was much higher than that of the ZOE or iRoot SP groups(P<0.05). A comparison of the sealing ability and antibacterial activity showed that the core-shell structured CaO/ZnO nanospheres-eugenol paste had significantly better effects than the ZOE and iRoot SP sealers(P<0.05). The core-shell structured CaO/ZnO nanosphere paste displayed excellent sealing and antibacterial properties, and it has promising application potential in endodontics.

  • A Perspective: the Technical Barriers of Zn Metal Batteries
    • Abstract: Abstract Energy storage will witness a leap of understanding of new battery chemistries. Considering the safety that cannot be compromised, new aqueous batteries may surface as the solutions to meet the immense market needs, where the growth of renewables is no longer limited by the lack of storage. Aqueous Zn-metal batteries are intriguing candidates to deliver the desirable properties and exhibit competitive levelized energy cost. However, the fact that most commercial Zn batteries are primary batteries states the difficulty of reversibility for the reactions of electrodes in such batteries. This article will highlight the practical needs that guide the development of storage batteries. The causes of irreversibility for both cathode and zinc metal anode are discussed, and the potential solutions for these challenges are summarized. Zn metal batteries may one day address the storage needs, and there exists a vast potential to further improve the properties of reactions in this battery.

  • Facile Synthesis of Bi 2 MoO 6 Nanosheets@Nitrogen and Sulfur Codoped
           Graphene Composites for Sodium-ion Batteries
    • Abstract: Abstract Recently, sodium-ion batteries gradually become the promising alternative to lithium-ion batteries because of cost considerations. In this work, a kind of Bi2MoO6 nanosheets@N,S codoped graphene composite is designed and fabricated for sodium storage applications. Detailed characterizations are employed to investigate its morphology, structure and chemical compositions. When evaluated as an anode material for sodium-ion batteries, the as-prepared composite is able to display a specific capacity of 254 mA·h/g after 50 cycles at a current density of 0.2 A/g, and 186 mA·h/g at 1.6 A/g during the rate capability test. As a result, the further morphology and structure optimization is still required for high performance sodium-ion batteries.

  • Cu 2 SnSe 3 /CNTs Composite as a Promising Anode Material for Sodium-ion
           Batteries
    • Abstract: Abstract Metal selenides as anode materials for sodium-ion batteries have attracted considerable attention owing to their high theoretical specific capacities and variable composition and structures. However, the achievement of long cycle life and superior rate performance is challenging for these selenide materials due to the volume variation upon cycling. Herein, a composite composed of a new binary-metal selenide[Cu2SnSe3(CSS)] and carbon nanotubes(CNTs) was constructed via a hydrothermal process followed by calcination at 600 °C. Benefited from the unique structure of binary-metal selenide and the conductive network of CNTs, the Cu2SnSe3/carbon nanotubes(CSS/CNT) composite exhibits excellent electrochemical performance when used as an anode material for sodium-ion batteries. A reversible specific capacity of 399 mA·h/g can be maintained at a current density of 100 mA/g even after 100 cycles. This work provides a promising strategy for rational design of binary-metal selenides upon delicate crystal phase control as electrode materials.

  • Ball-milling Synthesis of Tetrahydroquinolines via ‘One-pot’
           Three-component Diels-Alder Reaction Catalyzed by Phosphotungstic Acid
    • Abstract: Abstract We reported an economic and practical ball-milling method for the synthesis of tetrahydroquinoline derivatives via a ‘one-pot’ three-component Diels-Alder reaction of anilines, aldehydes and alkenes catalyzed by phosphotungstic acid at room temperature. For this reaction, a simple “one-pot” ball-milling operation was conducted, readily available starting materials were employed, ‘one-pot’ conditions were applied, and the most important was to use inexpensive and environmentally friendly catalyst phosphotungstic acid. Various tetrahydroquinolines, which might be potentially applicable in the pharmaceutical and biochemical areas, were conveniently synthesized in moderate to excellent yields.

  • Intercalation Effect in NiAl-layered Double Hydroxide Nanosheets for CO 2
           Reduction Under Visible Light
    • Abstract: Abstract Photocatalytic reduction of CO2(CO2PR) to valuable solar fuels is considered as a promising route to the amelioration of fossil fuel conundrum and the mitigation of greenhouse gases. Although progress has been made to enhance CO2PR performance, the available method that can promote the selectivity of CO2PR products remains to be a challenge. In this work, we synthesized NO3− or CO32− intercalated NiAl-layered double hydroxide(NiAl-LDH) photocatalysts and investigated the performance of CO2PR in the presence of an electron donor and a photosensitizer. Compared with Ni2Al-CO32−, Ni2Al-NO3− exhibited superior catalytic performance in the CO2PR, and the resulted selectivity of CH4 in Ni2Al-NO3−(6.1%) was 12.2 times that of Ni2Al-CO32−(0.5%) under visible light irradiation. X-Ray absorption fine structure(XAFS) result reveals a relative abundance of defects in Ni2Al-NO3−, which played as active sites and promoted charge transfer in CO2PR for the efficient CH4 evolution.

  • Boosting the Energy Density of Flexible Asymmetric Supercapacitor with
           Three Dimensional Fe 2 O 3 Composite Brush Anode
    • Abstract: Abstract Flexible asymmetric supercapacitor is fabricated with three dimensional(3D) Fe2O3/Ni(OH)2 composite brush anode and Ni(OH)2/MoO2 honeycomb cathode. Particularly for 3D composite brush anode, a layer of thin Fe2O3 film is firmly adhered on a 3D Ni brush current collector with the assist of Ni(OH)2, functioning as both adherence layer and pseudocapacitive active material. The unique 3D Ni brush current collector possesses large surface area and stretching architecture, which facilitate to achieve the composite anode with high gravimetric capacitance of 2158 F/g. In terms of cathode, Ni(OH)2 and MoO2 have a synergistic effect to improve the specific capacitance, and the resulting Ni(OH)2/MoO2 honeycomb cathode shows a very high gravimetric capacitance up to 3264 F/g. The asymmetric supercapacitor(ASC) has balanced cathode and anode, and exhibits an ultrahigh gravimetric capacitance of 1427 F/g and an energy density of 476 Wh/kg. The energy density of ASC is 3–4 times higher than those of other reported aqueous electrolyte-based supercapacitors and even comparable to that of commercial lithium ion batteries. The device also shows marginal capacitance degradation after 1000 cycles’ bending test, demonstrating its potency in the application of flexible energy storage devices.

  • Geometric and Electronic Behavior of C 60 on PTCDA Hydrogen Bonded Network
    • Abstract: Abstract Self-assembled supramolecular networks are promising spacer layer for electronic decoupling from the metal substrate. However, the mechanism behind of how the intrinsic electronic structure of spacer layers affects the adsorbate is still unclear. Here a hydrogen bonded network composed of n-type semiconducting molecules 3,4,9,10-perylene-tetracarboxylic-dianhydride(PTCDA) is prepared under ultra-high vacuum to serve as a spacer layer for functional organics C60 on Au(111). The geometric and electronic information of C60 was investigated by scanning tunneling microscopy and scanning tunneling spectroscopy(STM/STS) at 5 K. Effective decoupling from the metal surface yields an energy gap of 3.67 eV for C602nd, merely considering the HOMO-LUMO peak separation. The broadening of resonance peaks in STS measurements however indicates unneglected interlayer interactions in this hetero-organic system. Moreover, we scrutinize the nucleation sites of C60 on PTCDA layer and attribute this to the decreased diffusion capability on a less dense molecular arrangement possessing inhomogeneous spatial distribution of unoccupied molecular orbitals.

  • Stabilizing High-voltage Cathode Materials for Next-generation Li-ion
           Batteries
    • Abstract: Abstract The pressing demand for high-energy/power lithium-ion batteries requires the deployment of cathode materials with higher capacity and output voltage. Despite more than ten years of research, high-voltage cathode materials, such as high-voltage layered oxides, spinel LiNi0.5Mn1.5O4, and high-voltage polyanionic compounds still cannot be commercially viable due to the instabilities of standard electrolytes, cathode materials, and cathode electrolyte interphases under high-voltage operation. This paper summarizes the recent advances in addressing the surface and interface issues haunting the application of high-voltage cathode materials. The understanding of the limitations and advantages of different modification protocols will direct the future endeavours on advancing high-energy/power lithium-ion batteries.

  • Nanostructured BiVO 4 Derived from Bi-MOF for Enhanced Visible-light
           Photodegradation
    • Abstract: Abstract BiVO4, a promising visible-light responding photocatalyst, has aroused extensive research interest because of inexpensiveness and excellent chemical stability. However, its main drawback is the poor photoinduced charge-transfer dynamics. Building nanostructures is an effective way to tackle this problem. Herein, we put forward a new method to prepare nanostructured BiVO4 from Bi-based metal-organic frameworks[Bi-MOF(CAU-17)] precursor. The as-prepared material has a rod-like morphology inherited from the Bi-MOF sacrificial template and consists of small nanoparticle as building blocks. Compared with its counterparts prepared by conventional methods, MOF-derived nanostructured BiVO4 shows better light absorption ability, narrower bandgap, and improved electrical conductivity as well as reduced recombination. Consequently, BiVO4 nanostructure demonstrates high photocatalytic activity under visible light towards the degradation of methylene blue. Methylene blue can be degraded up to 90% within 30 min with a reaction rate constant of 0.058 min−1. Moreover, the cycling stability of the catalyst is excellent to withstand unchanged degradation efficiency for at least 5 cycles.

  • Recent Advances in Two-dimensional Materials for Electrochemical Energy
           Storage and Conversion
    • Abstract: Abstract With the increased energy demand, developing renewable and clean energy technologies becomes more and more significant to mitigate climate warming and alleviate the environmental pollution. The key point is design and synthesis of low cost and efficient materials for a wide variety of electrochemical reactions. Over the past ten years, two-dimensional(2D) nanomaterials that graphene represents have been paid much attention as a class of the most promising candidates for heterogeneous electrocatalysts in electrochemical storage and conversion. Their unique properties, such as good chemical stability, good flexibility, and good electronic properties, along with their nano-sized thickness and large specific area, make them exhibit comprehensively good performances for energy storage and conversion. Here, we present an overview on the recent advances in electrochemical applications of graphene, graphdiyne, transition metal dichalcogenides(TMDs), and MXenes for supercapacitors(SCs), oxygen reduction reaction (ORR), and hydrogen evolution reaction(HER).

  • Synthesis and Biological Evaluation of Novel Anthranilic Diamides
           Containing N -H/CH 3 -1 H -Pyrazole
    • Abstract: Abstract In order to systematically study the structure-activity relationship of anthranilic diamides and develop insecticides with simple structure and high efficiency, a series of novel anthranilic diamides containing N-H/CH3-1H-pyrazole was designed and synthesized. Their chemical structures were characterized by 1H NMR spectra, high resolution mass spectrometry(HRMS) or 13C NMR spectra. The preliminary bioassay results indicated that all title compounds displayed moderate insecticidal activity against oriental armyworm(Mythimna separata) at 200 mg/L and fungicidal activities against six kinds of fungi at 50 mg/L, especially compound 5i showed 50% insecticidal activity at 25 mg/L. In addition, some compounds exhibited certain antitumor activities. It was demonstrated that the introduction of CH3 group into pyrazole ring was superior to H for the insecticidal activity.

  • Remarkably Enhanced Hydrogen Oxidation Reaction Activity of
           Carbon-supported Pt by Facile Nickel Modification
    • Abstract: Abstract Developing high activity catalysts for hydrogen oxidation reaction(HOR) under alkaline condition remains a challenge in the exchange membrane fuel cell(AEMFC). Herein, we report that the activity of carbon-supported platinum(Pt/C) towards the hydrogen oxidation reaction(HOR) in alkaline media can be remarkably enhanced by simple immersion of Pt/C in nickel chloride solution. The adsorption of hydrogen on the catalyst surface is weakened by modification of nickel. The HOR activity on the Pt/C after immersion possesses an excellent mass current density of 33.4 A/gmetal, which is 18% higher than that(28.3 A/gmetal) on Pt/C.
