Gold nanoparticles are small gold particles with a diameter of 1 to 100 nm which, once dispersed in water, are known as colloidal gold.
A small amount of gold is used in almost every sophisticated electronic device, including smart phones, computers, televisions, and household appliances.
Silver is a common yet vital catalyst that produces industrial chemicals that are used to manufacture plastics, textiles, adhesives, and laminating resins.
Gold is durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form.
Silver is the most electrically conductive element, and it is also has the highest thermal conductivity of any element.
Around the house and in our places of work, pipes, joints, faucets, and electrical wires are joined together using heat – a process called soldering.
Though it’s been used in medicine for years, scientists have only recently begun to understand how silver works to protect against bacterial infections.
To power our cars, motorcycles, trains, and airplanes, engines convert heat into mechanical energy.
Silver is the most reflective element, and polished silver reflects 95% of the visible light spectrum.
Because it is an excellent reflector of infrared light, gold is a critical component of an exciting new space telescope set to be launched by NASA in 2021.
