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.
A dash of this, a pinch of that, and it seems researchers at Northwestern have cooked up a new class of nanostructures that aren't just ideal for such applications as gas storage or medical technologies, but also edible. The team, which began their research with a completely different outcome in mind, found that their recipe produced natural and edible metal-organic frameworks (MOFs), porous crystalline structures with unique properties that are usually difficult to make and composed of toxic petroleum products.
