Adelaide University researchers have demonstrated that a naturally derived seaweed compound can dramatically reduce methane emissions from beef cattle raised in extensive grazing systems, without harming calves.

Researchers have uncovered the fundamental mechanism behind persistent dark current in Te-Se alloy-based infrared photodiodes, identifying interface metallization as the culprit. High interface stress between Te_0.6Se_0.4 and ZnO causes Se atoms to diffuse, forming a detrimental Te_0.75Se_0.25 metallic phase that hinders carrier transport. By introducing an innovative TeO₂ modification layer, scientists successfully mitigated interface stress, prevented metallization, and dramatically improved device performance with significantly reduced dark current and enhanced quantum efficiency. This breakthrough in interface engineering opens new possibilities for high-performance infrared detection technologies in applications ranging from autonomous driving to medical imaging and space exploration.
