Summary: The oral anthrafuran drug exhibited reversible and dose-dependent hepatic and renal toxicity at low doses, as well as hematological and gastrointestinal toxicity at high doses, without limiting cardio- and myelotoxicity. The favorable toxicological properties observed during the subchronic study make oral anthrafuran a promising candidate for further research compared to clinical anthracyclines, oral idarubicin, or parenteral doxorubicin.

Summary: The study found that subchronic intoxication induced by lead oxide and cadmium oxide nanoparticles, either alone or in combination, significantly reduced the mechanical work of myocardial preparations and decreased the sliding velocity of regulated thin filaments. These cardiotoxic effects were influenced by the toxic impact, toxicant doses, stretching of cardiomyocytes, and muscle type studied. Some of the toxic and genotoxic effects could be partially or fully normalized when intoxication occurred alongside the administration of a bioprotective complex.

Summary: In this study, a thermal annealing and high temperature poling approach is proposed to enhance the piezoelectricity of Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 crystals. The manipulation of defects and defect polarization orientation results in a more polarized crystal. The improved piezoelectric property achieved under a maintained Curie temperature indicates the feasibility of the approach.

Summary: In this paper, a cooperative optimization strategy is proposed to achieve outstanding energy-storage performance in NBST-based ceramics. Substituting NN for NBST generates an ergodic state and induces polar nanoregions. Applying VPP to the ceramics further increases compactness and breakdown strength. The optimized ceramics possess improved energy-storage characteristics and temperature adaptability.

Summary: The ordering of isolated circular ferroelectric nanodomains was observed in lithium tantalate crystals through multiple scanning with infrared laser irradiation. This ordering effect was attributed to domain formation and growth under the influence of alternating pyroelectric field during heating and cooling processes. Circular domains appeared due to 1D to 2D shape transformation and grew by merging with newly formed domains during subsequent scanning. The ordering of the domain pattern was characterized by an increase in the autocorrelation function peak, indicating domain interaction. This mechanism was confirmed through computer simulation based on the analogy between domain and crystal growth. The discovered domain ordering effect bears similarity to similar effects in magnetic materials.

Summary: High recoverable energy storage density (W-rec) and high energy storage efficiency (eta) are urgently needed for their potential application in pulse capacitor devices. However, low eta and breakdown strength (BDS) have hindered the achievement of high W-rec at high electric field. In this study, Bi(Mg0.5Ti0.5)O-3 (BMT) was introduced into Ba(Ti0.92Sn0.08)O-3 (BTS) matrix to enhance the relaxor character and reduce electrostrictive strain. The results showed significantly improved BDS and a high W-rec of 4.34 J/cm(3) with excellent temperature stability.

Summary: Lithium-niobate-based waveguides are important platforms for integrated optical technologies. In this paper, we propose a method for creating an integrated optical frequency conversion device using focused ion beam (i-beam) periodical poling technique after the soft proton exchange (SPE) process. The study reveals that the SPE process leads to the formation of shallow isolated nanodomains, which is preferable for periodical poling. We successfully create a high-quality 2-μm-period domain structure in a channel waveguide.

Summary: This experimental study investigates the kinetics of abnormal domain structure in lithium niobate single crystals with a surface layer modified by soft proton exchange. Two types of domain structure evolution were observed: the traditional growth of hexagonal domains at fields higher than 21.5 kV/mm and the abnormal growth of stripe domains at fields ranging from 3.8 to 21.5 kV/mm. The formation and growth of stripe domains were analyzed using a modified Kolmogorov-Avrami approach, and a controllable creation of quasi-periodic stripe domains was demonstrated. The abnormally low threshold fields were attributed to the presence of a built-in field induced by soft proton exchange.

Summary: Natural diamonds were investigated using advanced chemical and structural analytical tools to comprehensively characterize their optically blind and optically active nitrogen impurity centers. The study established compositional relationships between X-ray photoelectron spectroscopy and Fourier-transform infrared vibrational spectroscopy signals of nitrogen impurity defects, and correlated depth-dependent spatial distributions of photoluminescence-active nitrogen defects with the carbon lattice signals. The study also revealed connections between local structural defects and stress-sensitive impurity distributions in bulk diamonds. These findings demonstrate the instrumental opportunities for in situ studies of diamond micro-features.

Summary: Electrocaloric refrigeration is an emerging solid-state technology with advantages of high efficiency, miniaturization, eco-friendliness, and low cost. This paper investigates Ba(Ti1-xSnx)O-3 ceramics and reveals their structural, dielectric, ferroelectric, electrocaloric, and electrostrictive characteristics. The results show that increasing Sn4+ concentration leads to lower dielectric peaks and a phase diagram is constructed based on dielectric characteristics. The study also demonstrates a giant adiabatic temperature change of 6.36 K in the x = 0.04 ceramic sample and temperature and composition-insensitive electrostrictive behavior.

Summary: Industrial production generates complex aerosols with ultrafine particles, which are dangerous components of inhaled air. This study investigated the cytotoxicity of different nanoparticles based on their chemical nature and dose. Tests on rats exposed to nanoparticles of CuO, PbO, CdO, Fe2O3, NiO, SiO2, Mn3O4, and SeO were conducted, and it was found that cytotoxicity varied depending on the chemical nature and dose of the nanoparticles. Changes in cytological and biochemical parameters of bronchoalveolar lavage fluid were observed, indicating the cytotoxic effects of nanoparticles. These findings suggest that cytological and biochemical analysis can be used to predict the potential danger of new nanomaterials.
