Redesigning combustion synthesis for coupled co-production of SiC and Si3N4 powders

A new approach enables simultaneous synthesis of SiC and Si3N4 powders with improved quality and reduced diluent usage. High-purity powders are achieved through optimized temperature field regulation and CO concentration control. The method paves the way for large-scale, low-cost manufacturing of high-performance Si-based ceramics.

World Health Organization’s priorities shaped by its reliance on grants from donor organisations such as the Gates Foundation

The World Health Organization's (WHO) priorities are skewed by its reliance on donations from the Gates Foundation, which has directed over half of its $5.5 billion in grants towards vaccine-related projects and polio. In contrast, non-communicable diseases and health systems strengthening remain underfunded.

Turning waste into clean water: Magnetic carbon materials remove toxic pollutants from wastewater

Researchers have developed magnetic carbon adsorbents made from flax shives and eucalyptus sawdust to effectively remove toxic chemicals like pentachlorophenol from water. The materials demonstrated outstanding performance in removing up to 95% of PCP, showing excellent stability and minimal loss of performance.

How can (A)I help you?

A new study by Yifan Yu offers guidance on how to deploy emotion AI in various scenarios, emphasizing the importance of balancing human involvement with AI's emotional detection capabilities. The analysis showed that emotion AI works best when integrated with human employees, and some scenarios are better handled by humans alone.

Home treatment with IV antibiotics could relieve NHS pressure

A University of East Anglia study found that treating patients at home with IV antibiotics can save the NHS over £3,500 per patient and potentially free-up vital hospital beds. The treatment involves having antibiotics prepared at home and continuously delivered into the bloodstream by an elastomeric pump.

As ochre sea star ‘baby boomers’ grow up, species showing signs of recovery

New research reveals many encouraging signs for ochre sea star populations, with many baby boomers reaching adulthood and population numbers exceeding pre-wasting disease abundances. However, the average body sizes of the sea stars are still smaller than before, and the populations coast-wide are generally less steady from year to year.
