Recently, high‐entropy perovskites have attracted considerable attention due to their diverse chemical composition and multifunctionality. In this study, the high‐entropy approach was employed in a (Bi0.4Na0.2K0.2Ba0.2)TiO3 matrix, and Nd3+ was introduced to enhance the configurational entropy and modify its dielectric and ferroelectric properties. Notably, despite Nd3+ doping, all samples maintained a tetragonal perovskite structure at room temperature. The configurational entropy increased with the Nd3+ concentration, consequently leading to a gradual decline in the ferroelectric properties along with the associated temperature (Tm) and maximum dielectric constant (εm). The P–E loops of the ceramics also became thinner as Pm and Pr decreased, resulting in a slow decrease in the recoverable energy density (Wrec) and a simultaneous increase in the energy storage efficiency (η). Especially, the energy storage performance reached its peak at an Nd3+ concentration of 12 mol%, exhibiting an energy storage efficiency of 85.8% and a recoverable energy storage density of 0.74 J/cm3 at a low electric field of 100 kV/cm. These results highlight the potential of this material for dielectric applications in low electric fields and contribute to the advancement of alternative high‐entropy energy storage perovskite ceramics.

Recently, high‐entropy perovskite oxides (HEPOs) have received increasing interest for energy storage applications owing to their unique structure, huge composition space, and promising properties. However, designing HEPOs with improved energy storage performance remains a challenge. In this study, various HEPOs were designed by partially replacing Zr4+ for Ti4+ in (Bi0.4Ba0.2K0.2Na0.2)TiO3 medium‐entropy ferroelectric ceramics. The resulting ceramics exhibited a pseudo‐cubic structure. With increasing Zr4+ content, the ceramics gradually transformed into relaxor ferroelectrics. The energy storage performance of the ceramics depended on the Zr4+ content. The sample with 20 mol% Zr4+ showed the best energy storage performance with a maximum reversible energy density of 2.47 J/cm3 and an energy storage efficiency of 82.3% at a low applied electric field (224 kV/cm). This study obtained a promising material for the new generation dielectric energy storage capacitors and provided a novel method for enhancing energy storage performance. [ABSTRACT FROM AUTHOR]

To develop nutritional oil similar to Chinese human milk in terms of fatty acids composition and triglyceride, several vegetable oils and 1,3‐dioleoyl‐2‐palmitoylglycerol (OPO) were selected to prepare nutritional oil microcapsule. The result showed that human milk fat substitute (HMFS) prepared by these oils (soybean oil (SO): camellia oil (CMO): high oleic sunflower oil (HOSO): corn oil (CRO): OPO = 28.24:0.00:12.94:8.82:50.00) was the optimal formula. After spray drying, the final microcapsule product was milky white with good solubility and microencapsulation efficiency (MEE = 92.1%). The dispersion coefficient of the microcapsule particle size distribution was 0.200 and the average particle size was 202.767 nm, both particle size distribution experiment and scanning electron microscope (SEM) analysis indicated that the particle size of the microcapsule was uniform and the surface was smooth, After 30 days' accelerated experiment, the peroxide value of microcapsule products was 10.24 meq/kg, indicating the product had good oxidative stability. Practical applications: Human milk is considered the most ideal food source for newborns, but not all cases have human milk for infant. Therefore, it is necessary to produce formula milk powder whose composition and function are closer to human milk. This study used five commonly edible oils and added OPO to develop a HMFS similar to human milk in fatty acids and triglycerides. The optimal formula contributed to long shelf life (27 months) and good physicochemical properties, promoting the development of HMFS. [ABSTRACT FROM AUTHOR]

The burgeoning requirement for compact electronic devices has intensified research into lead‐free dielectric ceramics that offer superior recoverable energy storage density and efficiency at low electric fields. In this study, we report the synthesis of Nd3+‐doped (Bi0.4K0.2Na0.2Sr0.2)TiO3 perovskite ceramics via the solid‐state reaction technique. The synthesized ceramics adopted a tetragonal crystal structure. As the concentration of Nd3+ ions increased, both the maximum dielectric constant (εm) and its corresponding temperature (Tm) decrease. The incorporation of Nd3+ ions perturbed the long‐range ferroelectric order, leading to diminished maximum polarization (Pm) and remanent polarization (Pr). The ceramics achieved optimal properties with 12 mol% Nd3+ doping, showcasing a significant recoverable energy storage density of 1.50 J/cm3 at a low electric field of 140 kV/cm, along with an exceptional storage efficiency of 94.6%. This research not only highlights a promising candidate for dielectric materials in low electric field applications but also introduces an innovative approach to enhance energy storage performance.

This review critically evaluates current in vitro gastrointestinal models for assessing infant formulas from a perspective focusing on a process along digestion, absorption and microbial fermentation. Despite their potential, none of the current in vitro gastrointestinal models fully considers the dynamics and continuous upstream‐downstream process of the human digestive tract. Considering the substantial differences between infants and adults, there is a pressing need for whole‐process gastrointestinal models tailored to infants. Developing such models is crucial for accurately assessing infant formula nutritional value and physiological function, enhancing the formulation of infant formulas to better meet the needs of infants.
