Gold’s remarkable properties find yet another critical application in the aviation industry, particularly in the construction of airplanes. Gold-coated films, applied to the windows of commercial and military aircraft, serve as a vital safeguard against electromagnetic interference (EMI) and radiofrequency interference (RFI). These thin layers of gold effectively block out unwanted signals, ensuring the smooth operation of avionics systems and communication equipment on board. Furthermore, the aerospace industry relies on gold’s exceptional corrosion resistance and electrical conductivity for various connectors, switches, and sensors within the aircraft, contributing to the safety and efficiency of air travel worldwide. Whether you’re cruising at 30,000 feet or soaring above the clouds, gold’s hidden role in aviation helps keep you connected and secure during your journey.
Medicine and Healthcare
In the field of medicine, gold is employed in various ways. Gold nanoparticles are used in diagnostic tests, such as pregnancy tests and HIV tests, to detect specific biological markers accurately. Additionally, gold is used in the treatment of certain medical conditions, such as rheumatoid arthritis, through gold salts and compounds.
