Nanocages Trap and Separate Elusive Noble Gases

Researchers have discovered how two-dimensional nanoscale cages trap some noble gases. These cages can trap atoms of argon, krypton, and xenon at above freezing temperatures. Noble gases are hard to trap using other methods because they condense at...

Parker Spiral Created in the Laboratory for the First Time Ever

The Sun is a spinning ball of plasma that generates its own magnetic field. As the Sun spews out plasma, it generates solar wind that pulls the Sun’s magnetic field along with it, twisting the magnetic field into what is called a Parker spiral. A...

New Polymers that Close the Loop in Plastics Recycling

Scientists have designed a recyclable plastic called poly(diketoenamine)s, or PDKs. In contrast to many plastics, scientists can recover and free the monomers of PDK plastic from each other and additives by dunking it in a highly acidic solution....
