A novel method of treatment high-salinity nitrogenous wastewater: Halomonas venusta TJPU05

A novel salt-tolerant HN-AD bacterium, Halomonas venusta TJPU05, was isolated and demonstrated excellent potential in treating high-salinity nitrogenous wastewater. The study showed that 86.12% of NH4+-N, 95.68% of NO3––N, 100% of NO2––N and 84.57% of total nitrogen (TN) could be removed from simulated water within 24 hours.

Scientists fine-tune “tweezers of sound” for contactless manipulation of objects

Researchers have enhanced technology to lift small particles using sound waves, achieving stable lifting of particles from surfaces. By fine-tuning control using an adaptive algorithm, they have improved the stability of their 'acoustic tweezers' technology, which could be deployed in space and other environments with minimal contact.
