A new potassium-containing copper-zeolite catalyst, Cu-SSZ-39-K, enables major progress in low-temperature diesel NO_xemission control. Its higher fraction of Al in 8-memberedringspromotes the formation of more active [Cu(OH)]⁺-Z species, nearly doubling NO_x conversion at 150-225°C compared with conventional Cu-SSZ-39. The catalyst also maintains highly stable and excellent performance after 800°C hydrothermal ageing.With its enhanced activity and high-yield synthesis, Cu-SSZ-39-K offers a scalable route to cleaner diesel emissions.

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that enables stable data transmission even under strong ambient light. By implementing a newly designed 8B13B coding scheme on an FPGA and interfacing it with a Raspberry Pi, the team achieved reliable outdoor VLC at data rates of up to 3.48 Mbit/s over distances of several meters. The approach addresses key challenges in VLC, including pulse distortion and sunlight interference, and offers a practical path toward intelligent transportation system (ITS) applications.

Scientists have created a groundbreaking, fully implantable neurostimulator made entirely of soft hydrogel to treat inflammatory bowel disease (IBD). Unlike traditional rigid and wired implants, this wireless device gently wraps around the splenic nerve. It receives power through the skin to deliver electrical pulses that calm gut inflammation by rebalancing the immune system. In animal studies, the device significantly alleviated colitis symptoms without causing scar tissue formation, paving the way for a new class of soft, bioelectronic therapies for chronic diseases.

Scientists have developed a novel Cr-based single-atom catalyst that enables highly efficient hydrogen peroxide (H₂O₂) production in acidic environments through an electrochemical process. This breakthrough, guided by molecular dynamics simulations, reveals a self-adjusting mechanism with the catalyst actively restructuring during the reaction, achieving exceptional selectivity that rivals or even surpasses that of conventional Co-based catalysts.

Recently, a research team led by Academician Lijun Wang at CIOMP under UCAS has systematically reviewed the latest advancements in transfer printing (TP) technology. The team detailed its practical applications in integrating III-V semiconductor devices into photonic integrated circuits (PIC), demonstrating its significant potential for developing high-performance, high-reliability PICs. Their work provides crucial theoretical guidance for improving transfer yield and precision, while also offering forward-looking insights into current technical challenges and future development directions for this technology.

An innovative CRISPR-Cpf1-endo-recombinase CauR co-edited platform was developed and successfully applied to the glutamate-producing strain Corynebacterium glutamicum S9114 for high-efficiency production of N-acetylglucosamine (GlcNAc).
