Abstract :

The practical applications of lithium-sulfur (Li-S) batteries are severely impeded by the shuttle effect of soluble lithium polysulfides (LiPSs), sluggish redox reaction kinetics, and insulating nature of sulfur and its discharge products (Li2S2/Li2S). Developing sulfur electrocatalysts with high electrocatalytic activity to accelerate the redox kinetics and polysulfide trapping is critical for Li-S batteries but remains a grand challenge. In this contribution, we demonstrate the delicate design and synthesis of oxygen-incorporated heterophase cobalt vanadium selenide nanoplates with dense crystalline/amorphous interfacial sites (denoted as DC/A O-CoVSe NPs) as high-efficiency sulfur electrocatalysts for Li-S batteries. Such DC/A O-CoVSe NPs possess high electronic conductivity and electrocatalytic activity. Besides, the abundant exposed crystalline/amorphous interfacial sites serve as efficient adsorption-catalytic centers to accelerate the conversion kinetics and alleviate the shuttle effect. Moreover, incorporation of oxygen further increases their affinity to LiPSs because of the introduction of more Li-O interactions. Benefiting from the multifarious advantages, Li-S batteries with DC/A O-CoVSe NP modified separators exhibit high discharge capacity (1400.1 mA h g-1 at 0.1C), excellent rate capability (683.8 mA h g-1 at 5C), and good long-term durability (672.4 mA h g-1 at 1C after 500 cycles with a low decay rate of 0.066% per cycle). Even at a high sulfur loading of 5.6 mg cm-2, the battery still delivers a decent reversible capacity of 658.8 mA h g-1 at 0.2C after 100 cycles, indicating its great potential for practical applications. This work could provide a rational viewpoint for developing high-efficiency sulfur electrocatalysts towards future advanced Li-S energy storage systems. Oxygen-incorporated heterophase cobalt vanadium selenide nanoplates with dense crystalline/amorphous interfacial sites (DC/A O-CoVSe NPs) are developed as high-efficiency sulfur electrocatalysts for lithium-sulfur batteries.

Abstract :

Amorphous transition metal oxides have recently received particular research interests in electrochemical energy storage. However, there is still a lack of direct comparisons between amorphous materials and their crystalline counterparts. Here, we demonstrate the rational synthesis of crystalline and amorphous Fe2O3 nanocubes uniformly grown on carbon nanofibers (denoted as CNFs@C-Fe2O3 and CNFs@A-Fe2O3, respectively) for lithiumion batteries (LIBs) and lithium-sulfur batteries (LSBs). In such a structure, the Fe2O3 nanocubes possess strong interfacial bonding with CNFs, which can ensure rapid electron transportation. Besides, these Fe2O3 nanocubes are highly porous, which can effectively alleviate the volume change, enlarge the surface area, increase active sites and facilitate ion diffusion. When employed as freestanding anode for LIBs, the CNFs@C-Fe2O3 electrode delivers much improved lithium ion storage performance compared to that of CNFs@A-Fe2O3. When evaluated as interlayers for LSBs, instead, the batteries with CNFs@A-Fe2O3 exhibit better rate performance cycling stability than that of with CNFs@C-Fe2O3. Moreover, theoretical calculations elucidate the amorphous Fe2O3 has stronger adsorption ability toward the soluble lithium polysulfides. This work would provide new insights into the reasonably development of crystalline and amorphous transition metal oxides toward electrochemical energy storage.

Abstract :

Rechargeable lithium-sulfur (Li-S) batteries have received ever-increasing attention owing to their ultrahigh theoretical energy density, low cost, and environmental friendliness. However, their practical application is critically plagued by the sluggish reaction kinetics, shuttling of soluble polysulfide intermediates, and uncontrollable growth of Li dendrites. Herein, a bimetallic telluride electrocatalyst with dense heterointerfaces and rich defects embedded in hollow carbon polyhedron bunches (N subset of CoTe1-x/ZnTe1-y@NC, abbreviated as NCZTC) is rationally designed to simultaneously address the S cathode and Li anode problems. Both experimental and computational results substitute the integration of dense heterointerfaces and rich defects can synergistically modulate the electronic structure, enhance the electrical conductivity, promote the Li+ transportation, strengthen the polysulfides adsorption and improve the catalytic activity, thereby significantly accelerating the redox conversion kinetics and prevent the dendrite growth. Consequently, Li-S batteries with NCZTC-modified separators demonstrate excellent electrochemical performance including high specific discharge capacity, remarkable rate capability, good long-term cycling stability, and competitive areal capacity even at high sulfur loading and lean electrolyte conditions. This study not only provides valuable guidance for designing efficient sulfur electrocatalysts with transition metal tellurides but also emphasizes the importance of heterostructure design and defect engineering for high-performance Li-S batteries. The high-efficiency N subset of CoTe1-x/ZnTe1-y@NC electrocatalyst is rationally designed for Li-S batteries. Both experimental and theoretical results substantiate that the integration of dense heterointerfaces and rich defects (Te vacancy-induced N-doping) can synergistically accelerate the sulfur conversion and protect the lithium anode from corrosion. This study provides an innovative strategy for constructing high-performance sulfur electrocatalysts with transition metal tellurides. image

Abstract :

A simple and effective method for improving the biological activity of borate bioactive glass (BBG) is to perform dynamic flow treatment with simulated body fluid (SBF). The phosphate layer formed on the BBG surface during flow treatment enhances the biocompatibility of this bioglass. However, the micromechanism of the formation of highly bioactive mineralized products on the surface of BBG under dynamic flow treatment is not clearly understood. In this study, we investigated the effect of dynamic flow treatment on the biological properties of Al2O3-doped BBG. The results revealed that the SBF-treated Al2O3-doped BBG exhibits significantly reduced degradation rate and improved bioactivity. The characterization of the treated Al2O3-doped BBG by Fouriertransform infrared and solid-state NMR spectroscopies revealed that Al mainly exists in the form of fourcoordinated aluminum in BBG. During the dynamic flow treatment process, four-coordinated aluminum transforms into six-coordinated aluminum, which chemically interacts with PO43 to improve the biological activity of Al-BBG. In addition, the much more phosphate deposited on BBG sample containing less Al2O3 and promote hydroxyapatite formation on the glass surface. In vitro cell studies suggested that the Al2O3-doped BBG after treated by dynamic flow treatment boosts the proliferation of MC-3T3E1. This work demonstrates that dynamic flow treatment is a simple and effective method for improving the bioactivity of BBG and also expands our understanding of the micromechanics of the degradation and biomineralization of Al(2)O(3)(-)doped BBG.

Abstract :

Triggered by the expanding demands of semiconductor devices, strain engineering of two-dimensional transition metal dichalcogenides (TMDs) has garnered considerable research interest. Through steady-state measurements, strain has been proved in terms of its modulation of electronic energy bands and optoelectronic properties in TMDs. However, the influence of strain on the spin-orbit coupling as well as its related valley excitonic dynamics remains elusive. Here, we demonstrate the effect of strain on the excitonic dynamics of monolayer WS2 via steady-state fluorescence and transient absorption spectroscopy. Combined with theoretical calculations, we found that tensile strain can reduce the spin-splitting value of the conduction band and lead to transitions between different exciton states via spin-flip mechanism. Our findings suggest that the spin-flip process is strain-dependent, provides a reference for application of valleytronic devices, where tensile strain is usually existing during their design and fabrication.

Abstract :

Inevitable dissolution in aqueous electrolytes, intrinsically low electrical conductivity, and sluggish reaction kinetics have significantly hampered the zinc storage performance of vanadium oxide-based cathode materials. Herein, core-shell N-doped carbon-encapsulated amorphous vanadium oxide arrays, prepared via a one-step nitridation process followed by in situ electrochemical induction, as a highly stable and efficient cathode material for aqueous zinc-ion batteries (AZIBs) are reported. In this design, the amorphous vanadium oxide core provides unobstructed ions diffusion routes and abundant active sites, while the N-doped carbon shell can ensure efficient electron transfer and greatly stabilize the vanadium oxide core. The assembled AZIBs exhibit remarkable discharge capacity (0.92 mAh cm(-2) at 0.5 mA cm(-2)), superior rate capability (0.51 mAh cm(-2) at 20 mA cm(-2)), and ultra-long cycling stability (approximate to 100% capacity retention after 500 cycles at 0.5 mA cm(-2) and 97% capacity retention after 10 000 cycles at 20 mA cm(-2)). The working mechanism is further validated by in situ X-ray diffraction combined with ex situ tests. Moreover, the fabricated cathode is highly flexible, and the assembled quasi-solid-state AZIBs present stable electrochemical performance under large deformations. This work offers insights into the development of high-performance amorphous vanadium oxide-based cathodes for AZIBs.

Abstract :

Lithium-sulfur batteries (LSBs) are appealing energy storage systems by virtue of the high theoretical energy density and abundant resources of sulfur. However, the sluggish redox reaction kinetics and shuttle effect of soluble lithium polysulfides (LiPSs) seriously restrict their practical applications. Searching for highly efficient and low cost electrocatalysts towards LiPSs conversion is one of the most promising approaches to relieve the shuttle effect and enhance the sulfur utilization. In this work, we first demonstrate the application of ternary iron molybdenum nitride hybridized with nitrogen-doped carbon, denoted as (Fe0.81Mo0.19)MoN2/NC composite, as an advanced separator modifier to boost the bidirectional catalytic conversion of LiPSs. Impressively, the as-fabricated LSBs with (Fe0.81Mo0.19)MoN2/NC modified separator display an ultrahigh initial discharge capac-ity of 1366.1 mAh g-1 at 0.1 C and still remains a high value of 809.1 mAh g-1 at a high rate of 4 C. Furthermore, a remarkable discharge capacity of 569.2 mAh g-1 is retained when cycling at a high rate of 1 C for 700 cycles (corresponding to a low attenuation rate of 0.065 % per cycle), indicating the good long-term cycling stability. The excellent performance could be attributed to the multiple advantages of high electrical conductivity, numerous active sites, strong adsorption ability and excellent catalytic activity, thereby effectively suppressing the shuttle effect of LiPSs. The present work indicates that the ternary transition metal nitrides could be promising separator modifiers for high-performance LSBs.

Abstract :

Nonlinear multi-phonon (2-7) absorption in the Na+/Bi3+-alloyed Cs2AgInCl6 lead-free double perovskites with similar to 100% photoluminescence quantum yield and superior stability is observed for the first time, which can be pumped by a femtosecond laser in a wide spectral range (800-2600 nm). First-principles calculations verify that the parity-forbidden transition from the valence band maximum and conduction band minimum (at the Gamma point) is not broken by Na+/Bi3+ doping, and strong optical band-to-band absorption occurs at the L&X points. Time-resolved emission spectra evidence that single-photon and multi-photon pumping leads to the same self-trapped exciton transition and high-order nonlinear absorption will not induce a remarkable thermal effect. Finally, we demonstrate that the Cs2Na0.4Ag0.6In0.99Bi0.01Cl6 DP shows great potential for next-generation wavelength-selective and highly sensitive multiphoton imaging applications.

Abstract :

Two-dimensional (2D) transition metal chalcogenides (TMDs) are regarded as promising materials for micro-optoelectronic devices and next-generation logic devices due to their novel optoelectronic properties, such as strong excitonic effects, tunable direct bandgap from visible to near-infrared regions, valley pseudospin degree of freedom, and so on. Recently, triggered by the growing demand to optimize the performance of TMDs devices, external field regulation engineering has attracted great attention. The goal of this operation is to exploit the external fields to control exciton dynamics in 2D TMDs, including exciton formation and relaxation, and to finally achieve high-performance 2D TMDs devices. Although the regulation strategies of exciton dynamics in 2D TMDs have been well explored, the underlying mechanisms of different regulation strategies need to be further understood due to the complex many-body interactions in exciton dynamics. Here, we first give a brief summary of the fundamental processes of exciton dynamics in 2D TMDs and then summarize the main field-regulation strategies. Particular emphasis is placed on discussing the underlying mechanisms of how different field-regulation strategies control varied fundamental processes. A deep understanding of field regulation provides direct guidelines for the integrated design of 2D TMDs devices in the future.
