A star's early chemistry shapes life-friendly atmospheres

Born in a disc of gas and rubble, planets eventually come together as larger and larger pieces of dust and rock stick together. They may be hundreds of light-years away from us, but astronomers can nevertheless watch these ...

Laying down a discerning membrane

One of the thinnest membranes ever made is also highly discriminating when it comes to the molecules going through it. Engineers at the University of South Carolina have constructed a graphene oxide membrane less than 2 nanometers ...

An energy-efficiency lead for nitrogen fertilizer production

Nitrogen and phosphorus fertilizers are essential in modern agriculture and crucial to meeting the ever-growing global food demand. Nitrogen fertilizer, in the form of ammonia, is produced now in the same way that it has ...

Size matters in nanocrystals' ability to adsorb, release gases

More efficient catalytic converters on autos, improved batteries and more sensitive gas sensors are some of the potential benefits of a new system that can directly measure the manner in which nanocrystals adsorb and release ...

Engineering at the atomic scale

Brian Shoemaker is helping a national team of scientists answer a million dollar question. Could a substance that resembles baby powder curb global carbon emissions?
