In the International Journal of Extreme Manufacturing, researchers have developed a technique that uses electric fields to anchor and stretch liquid metal, allowing it to freeze in mid-air to form unsupported 3D circuits.

In International Journal of Extreme Manufacturing, researchers have now created a compact security component made of stacked metal oxides that produces reliable hardware fingerprints and cryptographic keys across a broad temperature span from -50°C to 150°C.

- A research team led by Professors Seungbum Hong and Jong Min Yuk from the Department of Materials Science and Engineering and Professor Nam-Soon Choi from the Department of Chemical and Biomolecular Engineering has identified the cause of a measurement artifact in nanoscale battery analysis that can make surface topography appear to represent ion movement.

- The team has developed a method to reduce these artificial signals by smoothing rough battery-material surfaces, potentially improving the accuracy of analyses for next-generation batteries, including conventional lithium-ion batteries and emerging technologies such as sodium-ion and solid-state batteries.

A new study presents a mathematical model explaining why trees can support grass growth in dry environments but suppress it as rainfall increases. By separating the effects of canopy shade and tree roots, the researchers show when interactions shift from facilitation to competition, offering practical insights for afforestation, ecosystem restoration and land management.
