Ce-doped yttria transparent ceramic: A new ultraviolet-shielding material for extreme conditions
Ultraviolet (UV) radiation can break most of the chemical bonds in organic matter, and prolonged exposure to ultraviolet light can cause significant harm to humans and objects. In response, UV-shielding materials have been developed to fulfill variou.....»»
What did Bronze Age people do with all that bronze? New research revives old arguments about the nature of money
We have no written evidence about how people lived in Europe during the Bronze Age (2300–800 BCE), so archaeologists piece together their world from the artifacts and materials they left behind. Unlike perishable materials such as wool or wood, it'.....»»
Scientists identify the predictability limit of oceanic mesoscale eddy tracks in the South China Sea
Oceanic mesoscale eddies (OMEs) are swirling water structures that play a crucial role in ocean dynamics. These eddies transport heat, salt, nutrients, and other materials across the ocean, significantly influencing marine ecosystems and global clima.....»»
Scientists convert bacteria into efficient cellulose producers
Bacteria produce materials that are of interest to humans, such as cellulose, silk and minerals. The advantage of producing bacteria in this way is that it is sustainable, takes place at room temperature and in water. A disadvantage is that the proce.....»»
Balancing the seesaw: Simultaneously enhancing strength and elongation in metallic materials
Just as one side of a seesaw rises while the other falls, in the realm of metallic materials, "strength" and "elongation" typically conflict with each other. However, a collaborative team from POSTECH and Northwestern University has recently introduc.....»»
