Aerospace greets a new dawn: Private companies now compete for opportunities to explore the boundaries of space. These ongoing aerospace opportunities demand newer ideas for detecting and reducing particulate contamination. Fewer particle-induced defects lead to higher yields, lower cost and greater reinvestments in aerospace development. Combined with the rapid advances in microelectromechanical systems (MEMs), detecting nanoparticles is critical. There are emerging particle counting technologies for aerospace industries that give data analysis to help decisions on mission-critical operations and minimize particulates in processes.
