Cicada wings have long intrigued researchers due to their ability to kill and remove bacteria. These wings possess blunt spikes on their surface, and scientists have recently used simulations to investigate the functions of these spikes. This exploration of natural processes could provide valuable insights into addressing a crucial healthcare challenge. By understanding how cicada
Refrigeration plays a crucial role in our daily lives, but the current methods that rely on gases for cooling have significant drawbacks. These gases can be harmful to the environment, contributing to global warming. To address this issue, researchers from the Lawrence Berkeley National Laboratory and the University of California, Berkeley have developed a groundbreaking
Swedish researchers from Linköping University and the KTH Royal Institute of Technology have developed the world’s first wooden transistor. Although wood is not semiconductive, the researchers stripped hardwood balsa of its tough lignin and then filled the remaining material with a mixed electron-ion conducting polymer called PEDOT:PSS. By stacking millimeter-thick units that operated as electrodes
