With the rapid advancement of pulsed power electronics, electric vehicles, avionic systems, and renewable energy grids, dielectric capacitors have emerged as indispensable components due to their ultrahigh power density and ultrafast charge–discharge rates. Traditional lead-based dielectric ceramics, however, pose severe environmental and health hazards during their fabrication, usage, and disposal. Sodium bismuth titanate (Bi_0.5Na_0.5TiO₃, BNT)-based lead-free relaxor ferroelectric ceramics have attracted increasing attention as promising alternatives owing to the large spontaneous polarization induced by the Bi³⁺ 6s² lone-pair electron configuration and their broad operational temperature stability arising from diffuse phase transitions. Nevertheless, challenges remain in coordinating polarization response, dielectric breakdown strength (E_b), and relaxation behavior across different operational voltages. Therefore, developing field-tailored multiscale design strategies is essential to meet growing performance demands in diverse electrostatic energy storage applications.

Gastric cancer remains a major global health challenge, and therapeutic resistance continues to limit the effectiveness of existing HER2-targeted treatments. A research team from Jiangsu University has developed a bispecific cellular nanovesicle platform that simultaneously targets CD16-positive natural killer (NK) cells and HER2-positive gastric cancer cells. The engineered nanovesicles enhance NK cell recruitment, activation, cytokine secretion, and tumor-killing activity, providing a promising strategy for next-generation cancer immunotherapy.

River sediments are not simply passive sinks for polycyclic aromatic hydrocarbons (PAHs). A study combining global observations with multimedia modeling suggests that climate-driven changes in sediment–water exchange could increase future PAH concentrations and ecological risks in the Yangtze and Huanghe watersheds, while the St. Lawrence watershed may follow a different, lower-risk trajectory.

An ethylene carbonate (EC)-based electrolyte highly compatible with high-voltage LiNi_0.5Mn_1.5O₄ (LNMO) cathodes is developed. Two insights that go against conventional understanding are uncovered, i.e. contrary to the common belief that EC decomposes readily under high voltage, it demonstrates outstanding high-voltage stability; and LNMO cycles in this electrolyte without forming a typical cathode/electrolyte interphase, experiencing instead a unique surface restructuring.

Approximately one-third of fresh fruit is lost along the supply chain, with harvesting and grading representing major sources of loss. Inspired by the deformation mechanism of octopus suckers, the researchers developed a soft robotic gripper integrated with three-axis triboelectric tactile sensors. The system independently resolves normal and tangential forces and, within a single picking cycle, simultaneously assesses fruit firmness, enables damage-free harvesting, and measures fruit weight. Field trials demonstrated the feasibility of integrating non-destructive harvesting with in-field quality grading, offering a new pathway to reduce post harvest losses, streamline fresh-produce supply chains, and improve operational efficiency.
