Layered sodium trititanate (Na2Ti3O7) is a promising anode material for sodium-ion batteries due to its suitable charge/discharge plateaus, cost-effectiveness, and eco-friendliness. However, slow Na+ diffusion kinetics, poor electron conductivity, instability during cycling pose significant challenges practical applications. To address these issues, we developed template-free method synthesize Na2Ti3O7-C hollow microspheres. The synthesis began with polymerization-induced colloid aggregation...

Carbon nanocages (CNCs), with unique merits of morphology and structure, have attracted increasing attention for energy storage conversion. However, the synthesis CNCs reported so far suffers from relatively harsh conditions expensive raw materials. Herein, porous are intelligently designed using low-cost glucose as carbon precursor via a facile K-functionalized quantum dots (K-CQDs)-induced assembly route under hydrothermal process. The resulting cage-like large surface area, rich carboxyl...

Abstract Three‐dimensional (3D) pseudohalide rare‐earth double perovskites (PREDPs) have garnered significant attention for their versatile physical properties, including ferroelectricity, ferroelasticity, large piezoelectric responses, and circularly polarized luminescence. However, potential X‐ray detection remains unexplored, the low Curie temperature ( T C ) limits performance window PREDP ferroelectrics. Here, by applying chemical regulation strategies involving halogen substitution on...

To evaluate the risk of a pipe in water supply network Beijing, we used accident records gridding urban management (GUM) system. In addition, road and building information derived from three-dimensional (3D) electronic map was also employed. A machine learning algorithm, decision tree, employed to train dataset. The results show that contributions surrounding buildings roads are neglectable, except for super-high-rise buildings, which have limited contributions. This finding is consistent...

Recently, with the wide adoption of electric vehicles, transportation network has shown different characteristics and been further developed. In this paper, we present a new time-flow impedance function, which may be more realistic than existing functions. Based on an optimization model for mixed-mode traffic in battery vehicles (BEVs) gasoline (GVs) are chosen. We suggest two approaches to handle model: One is use interior point (IP) algorithm other employ sequential quadratic programming...

It is commonly known that for characteristics, such as long-distance, high-sensitivity, and full-scale monitoring, phase-sensitive optical time-domain reflectometry (Φ-OTDR) has developed rapidly in many fields, especially with the arrival of 5G. Nevertheless, there are still some problems obstructing application practical environments. First, fading effect leads to results falling into dead zone, which cannot be demodulated effectively. Second, because high sensitivity, Φ-OTDR system easy...
