A new type of cloth can guard against noxious gases and odors by trapping their molecules inside its fibers, according to Cornell University. A Cornell undergrad fashioned the cloth into protective head gear, seen here in a summery shade of turquoise.
The cloth is made of cellulose fibers and metal-organic framework molecules, crystalline compounds that form a porous structure. The pores can trap and store molecules of gas, serving as wearable filtration systems.
