Superior Temperature Sensing and Capacitive Energy-Storage Performance in Pb-Free Ceramics.

The ultrafast charge/discharge rate and high power density (P) endow lead-free dielectric energy storage ceramics (LDESCs) with enormous application potential in electric vehicles. However, their low energy storage density and single energy storage performance (ESP) limit their further development and applicability in rugged environments. Here, through the design of vacancy defects and phase structure regulation, Pb-free (BiNa)TiO-based ceramics with an optimal composition can achieve a large maximum polarization (>44 µC cm) under a moderate electric field (410 kV cm), resulting in an extremely high recoverable energy storage density (≈6.

Photoconductivity and Photovoltaic Effect Strengthened via Microstructural Cotuning in Ferroelectrics: Intuitively Assessed by Macroscopic Transparency.

Photoferroelectrics that involve strong light-matter coupling are regarded as promising candidates for realizing bulk photovoltaic and photoelectric effects via light absorption. Nonetheless, understanding the photoresponse mechanism or modulation of performance from a microscopic point of view is scarcely explored through quantification of macroscopic properties. Herein, we design a model material, Gd-doped (KNa)NbO ferroelectric-transparent ceramics, and present an advantageous strategy to enhance the optoelectronic coupling through joint modulations of lattice distortion and oxygen vacancies, along with inner defects and ferroelectric domains.

Giant Capacitive Energy Storage in High-Entropy Lead-Free Ceramics with Temperature Self-Check.

Considering the large demand for electricity in the era of artificial intelligence and big data, there is an urgent need to explore novel energy storage media with higher energy density and intelligent temperature self-check functions. High-entropy (HE) ceramic capacitors are of great significance because of their excellent energy storage efficiency and high power density (P). However, the contradiction between configurational entropy and polarization in traditional HE systems greatly restrains the increase in energy storage density.

Ultrathin Layered Structure and Oxygen Vacancies Mediated Efficient Charge Separation toward High Photocatalytic Activity in BiOIO Nanosheets.

Targeting mPGES-2 to protect against acute kidney injury via inhibition of ferroptosis dependent on p53.

Acute kidney injury (AKI) is a clinical syndrome with high morbidity and mortality but no specific therapy. Microsomal prostaglandin E synthase-2 (mPGES-2) is a PGE synthase but can metabolize PGH to malondialdehyde by forming a complex with heme. However, the role and mechanism of action of mPGES-2 in AKI remain unclear.

Cost-Effectiveness Analysis of Risk Factor-Based Lung Cancer Screening Program by Low-Dose Computer Tomography in Current Smokers in China.

Although the effectiveness of lung cancer screening by low-dose computed tomography (LDCT) could be shown in China, there could be variation in the evidence concerning the economic impact. Our study explores the cost-effectiveness of lung cancer screening and optimizes the best definition of a high-risk population. A Markov model consisting of the natural history and post-diagnosis states was constructed to estimate the costs and quality-adjusted life years (QALYs) of LDCT screening compared with no screening.

BiNaTiO/ZnO Z-scheme heterojunction for piezo-photocatalytic water remediation: Mechanical energy harvesting and energy band configuration.

The decaying photocatalytic rate caused by carrier recombination is a thorny problem that has not been properly solved. Improvement of photocatalysis can be achieved through structural innovation, diversification of catalytic modes, or a combination of both. Herein, effective separation of photo-generated carriers in BiNaTiO/ZnO composites was achieved by heterojunction construction for energy band regulation and synchronously mechanical energy harvesting from piezoelectric effect.

HO activated moxa ash ball milling for ultrafast removal of mitoxantrone.

As emerging contaminants, antineoplastic drugs are widely used, but their residues in water may cause long-term genotoxicity to aquatic organisms and human beings. Here, waste moxa ash was selected as biomass raw material and modified by ball milling to obtain carbon-based materials with excellent adsorption performance, which were used to remove the antineoplastic drug mitoxantrone (MTX) from water. The experimental results indicate that moxa ash modified by ball milling in hydrogen peroxide exhibits ultrafast removal of MTX (the removal efficiency reaches 97.

Phase Stability and Dual-Mode Photoluminescence Modulation in Er-Doped Lead Zirconate Titanate Antiferroelectrics.

The electric-field-modulation (-modulation) of photoluminescence (PL) properties in bulk ceramics has attracted tremendous interest due to its potential application in optical data storage and communication devices. One promising approach of reversibly and largely modulating the PL intensity has been proposed in rare-earth Er-doped PbLaZrTiO (PLZT) antiferroelectrics (AFEs) based on the unique -dependent antiferroelectric-ferroelectric (AFE-FE) phase transition. However, the AFE phase stability of PLZT doped with various Er contents and their -modulated PL properties have not been systematically investigated.

Recently, the lead-free piezoelectric material BiNaTiO (BNT) has been adopted for piezo-catalysis and synergistic catalysis, such as piezo-photocatalysis. Nonetheless, the catalytic effect of single BNT is too weak to degrade multifarious contaminants. Here, BNT and multi-walled carbon nanotubes (MWCNTs) composite were prepared and the catalytic performance of BNT was prominently boosted by introducing MWCNTs as the electron capturer.
