Perovskite quantum dots (PQDs)-based near-infrared light-emitting diodes (NIR-LEDs) still suffer from low external quantum efficiencies (EQEs) and severe efficiency roll-off. To overcome this challenge, an ionic liquid-mediated surface reconstruction strategy that simultaneously stabilizes PQD surface and enhances charge transport has been reported. This strategy enables NIR-LEDs achieve a record EQE of 24.8%, maintaining ~20% EQE at a radiance of 10 W sr^-¹ m^-²—representing the lowest efficiency roll-off for PQD-based NIR-LEDs reported to date.

(ϵ, δ)-Local Differential Privacy ((ϵ, δ)-LDP) ensures rigorous privacy protection for individual users without requiring trusted data aggregator, while enabling accurate statistical analysis of privatized data. Multiple (ϵ, δ)-LDP mechanisms have been developed to deal with data analysis tasks including frequency estimation of categorical data and mean estimation of numeric data. However, the (ϵ, δ)-LDP mechanism for set-valued data analysis has yet to be established.

Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of death worldwide. Elevated low-density lipoprotein cholesterol (LDL-C) is a major modifiable driver of ASCVD, and PCSK9 has become an important therapeutic target because it regulates hepatic LDL receptor recycling and circulating LDL-C levels. Although PCSK9-targeting monoclonal antibodies and siRNA therapies can substantially lower LDL-C, their cost and need for repeated administration have motivated efforts to develop longer-lasting and more accessible approaches.

A review by researchers from the Eye & ENT Hospital of Fudan University, ShanghaiTech University, and collaborators outlines recent progress in ocular gene therapy, covering molecular tools, delivery platforms, and disease applications. The article highlights that successful clinical translation will depend not only on the ability to edit or regulate genes, but also on matching the right therapeutic strategy, vector system, delivery route, and disease mechanism.

Researchers have engineered a multifunctional gallium-doped bioactive glass that selectively kills osteosarcoma cells and prevents bacterial infections while promoting bone regeneration. By localized delivery of gallium ions, this innovative biomaterial disrupts iron metabolism in cancer cells, triggering programmed cell death without harming healthy bone tissue. It simultaneously provides a robust defense against hospital-acquired pathogens like Pseudomonas aeruginosa.

Low impurity concentration is a key factor in achieving high‑performance devices in the semiconductor industry. However, the overlooked gas-phase impurities in thermal evaporation can severely degrade the optoelectronic performance of the films and devices. To address this issue, Chinese scientists have proposed a one‑step vapor purification method based on pre‑evaporation of reactive metals. The general effectiveness of this approach is expected to accelerate the development of thermally evaporated optoelectronic devices.
