Breakthrough in ice-repelling materials

Icy weather is blamed for multibillion dollar losses every year in the United States, including delays and damage related to air travel, infrastructure and power generation and transmission facilities. Finding effective, durable and environmentally stable de-icing materials has been stymied by the stubborn tenacity with which ice adheres to the materials on which it forms. …

A new way to remove ice buildup without power or chemicals

From airplane wings to overhead powerlines to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic failure. But preventing that buildup usually requires energy-intensive heating systems or chemical sprays that are environmentally harmful. Now, MIT researchers have developed a completely passive, solar-powered …

Novel flying robot mimics rapid insect flight

A novel insect-inspired flying robot, developed by TU Delft researchers from the Micro Air Vehicle Laboratory (MAVLab), is presented in Science (14 September 2018). Experiments with this first autonomous, free-flying and agile flapping-wing robot — carried out in collaboration with Wageningen University & Research — improved our understanding of how fruit flies control aggressive escape manoeuvres. Apart …
