Outstanding Energy Storage Performance of Na<sub>0.5</sub>Bi<sub>0.5</sub>TiO<sub>3</sub>‑BaTiO<sub>3</sub>‑(Sr<sub>0.85</sub>Bi<sub>0.1</sub>)(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub> Lead-Free Ceramics
Lead-free
(1 – x)(0.94Na0.5Bi0.5TiO3-0.06BaTiO3)-x(Sr0.85Bi0.1)(Mg1/3Nb2/3)O3 ((1 – x)(NBT-BT)-xSBMN) ceramics are synthesized using the traditional solid-state
reaction method. The introduction of SBMN leads to a dense microstructure
with small mean grain size. The temperature-dependent dielectric spectrum
reveals that the sample with x = 0.24 shows the best
temperature stability with TS occurring
around room temperature. A large recoverable energy storage density
value of 3.05 J/cm3, high efficiency of 89%, and excellent
temperature (25–140 °C)/frequency (1–100 Hz) stabilities
are simultaneously achieved in the ceramic. The variation of recoverable
energy storage density is less than 7% in the temperature range of
25–140 °C. The ceramic also has a high power density of
67.86 MW/cm3
Data_Sheet_1_An application of BWM for risk control in reverse logistics of medical waste.docx
The pollution posed by medical waste complicate the procedures of medical waste logistics (MWL), and the increasingly frequent occurrence of public health emergencies has magnified the risks posed by it. In this study, the authors established an index of the factors influencing the risks posed by MWL along five dimensions: the logistics business, emergency capacity, equipment, personnel, and management. The best-worst case method was used to identify the critical risk-related factors and rank them by importance. Following this, we assessed the risk posed by MWL in four major cities in China as an example and propose the corresponding measures of risk control. The results showed that the linking of business processes was the most important factor influencing the risk posed by MWL. The other critical risk-related factors included the location of the storage site, the capacity for emergency transportation, measures to manage emergencies, and the safety of packaging. Of the cities considered, Beijing was found to be a high-risk city, and its MWL needed to be improved as soon as possible in light of the relevant critical risks. Shanghai, Guangzhou, and Shenzhen were evaluated as general-risk cities, which meant that the risks of MWL were not a priority in these areas, and the other goals of urban development should be comprehensively considered during the long-term planning for MWL in these municipalities.</p
High-Entropy Design Toward Ultrahigh Energy Storage Density Under Moderate Electric Field in Bulk Lead-Free Ceramics
Electrostatic capacitors with ultrahigh energy-storage density are crucial for the miniaturization of pulsed power devices. A long-standing challenge is developing dielectric materials that achieve ultrahigh recoverable energy density Wrec ≥ 10 J cm−3 under moderate electric fields (30 ≤ E ≤ 50 kV mm−1). Herein, a specific high-entropy strategy is proposed to modulate the phase structure and interfacial polarization of medium-entropy base materials using linear dielectrics. This strategy ensures a sufficient polar phase and a high enough electric field for complete polarization, thereby achieving ultrahigh Wrec by enhancing polarization strength. The validity of this strategy is demonstrated in the (Na0.282Bi0.282Ba0.036Sr0.28Nd0.08)TiO3-xCa0.7Bi0.2TiO3 (NBBSNT-xCBT) (x = 0–0.15) system. The CBT-modulated samples exhibit a polyphase structure of R3c, P4bm, and Pm-3m with reduced remnant polarization (Pr). Additionally, the addition of CBT effectively suppresses interfacial polarization, enhancing the maximum polarization (Pmax). These factors significantly improve the value of ∆P = Pmax − Pr. As a result, an ultrahigh Wrec of 10.5 J cm−3 with a high-efficiency η of 80.3% is obtained in the x = 0.1 sample under a moderate electric field of 45 kV mm−1 for the first time. This work paves the way for achieving superior energy-storage performance under moderate electric fields
