Synthesis of a Sodium-Ion Cathode Material NaFe(SO)F with the Help of Fluorine Element.

The development of cathode materials has always been one of the most crucial areas of research in the field of sodium-ion batteries. Sulfate-based polyanionic materials, known for their high working voltage characteristics, have received widespread attention. In this work, a fluoro-sulfate sodium-ion battery cathode material, NaFe(SO)F modified with carbon nanotubes, was developed using a low-temperature solid-state annealing method.

The Asymmetry Observed between the Effects of Photon-Phonon Coupling and Crystal Field on the Fine Structure of Fluorescence and Spontaneous Four-Wave Mixing in Ion-Doped Microcrystals.

In this paper, we explore the asymmetry observed between the effects of photon-phonon coupling (nested-dressing) and a crystal field (CF) on the fine structure of fluorescence (FL) and spontaneous four-wave mixing (SFWM) in Eu: BiPO and Eu: NaYF. The competition between the CF and the strong photon-phonon dressing leads to dynamic splitting in two directions. The CF leads to static splitting in one direction under weak phonon dressing.

Postoperative screw pullout of severe spondylolisthesis in osteogenesis imperfecta: a case report with 3-year follow-up.

Introduction And Importance: Osteogenesis imperfecta (OI) is a rare skeletal disorder characterized by bone fragility and deformities in both paediatric and adult populations. The occurrence of severe spondylolisthesis in OI patients is even more infrequent. However, there is no consensus regarding the optimal treatment approach for OI patients afflicted with severe spondylolisthesis.

Identifying the Interfacial Polarization in Non-stoichiometric Lead-Free Perovskites by Defect Engineering.

Recent advances in perovskite ferroelectrics have fostered a host of exciting sensors and actuators. Defect engineering provides critical control of the performance of ferroelectric materials, especially lead-free ones. However, it remains a challenge to quantitatively study the concentration of defects due to the complexity of measurement techniques.

Enhanced NO Sensing Performance of ZnO-SnO Heterojunction Derived from Metal-Organic Frameworks.

Nitrogen dioxide (NO) is the major reason for acid rain and respiratory illness in humans. Therefore, rapid, portable, and effective detection of NO is essential. Herein, a novel and simple method to construct a ZnO-SnO heterojunction is fabricated by pyrolysis of bimetallic metal organic frameworks.

Enhancing Li-Ion Transport in Solid Electrolytes by Confined Water.

Developing new oxide solid electrolytes with fast Li-ion transport and high stability is an important step to realize high-performance solid-state Li-ion batteries. Hydrate materials containing confined water widely exist in nature or can be easily synthesized. However, they have seldom been explored as Li-ion solid electrolytes due to the stereotype that the presence of water limits the electrochemical stability window of a solid electrolyte.

MoS-Coupled Carbon Nanosheets Encapsulated on Sodium Titanate Nanowires as Super-Durable Anode Material for Sodium-Ion Batteries.

There is an ever-increasing demand for rechargeable batteries with fast charging, long cycling, high safety, and low cost in new energy storage systems. Herein, a heterogeneous architecture composed of MoS-coupled carbon nanosheets encapsulated on sodium titanate nanowires is developed and demonstrated as an advanced anode for sodium-ion batteries (SIBs). Owing to the synergistic effects of ultrastable substrate of 1D sodium titanate (NTO) nanowires, high-capacity promoter of 2D MoS nanosheets as well as the 2D conductive carbon matrix, the resulting 1D/2D-2D hybrid demonstrates excellent high-rate capacity and super-durable cyclability, delivering a stable capacity of up to 425.

Efficient Lithium-Ion Storage by Hierarchical Core-Shell TiO Nanowires Decorated with MoO Quantum Dots Encapsulated in Carbon Nanosheets.

Rational design and surface engineering are the key to synthesizing high-performance electrode materials for electrocatalysis and energy conversion and storage applications. Herein, a novel three-dimensional (3D) nanoarchitecture of TiO nanowires decorated with MoO quantum dots encapsulated in carbon nanosheets was successfully synthesized by a simple polymerization method. Such a hierarchical nanostructure can not only exhibit the synergistic effect of structural stability of a 1D TiO substrate and high capacity of 0D MoO quantum dots but also prevent the aggregation and oxidation of MoO.
