Exploring the properties of very thin hafnium dioxide

The chemistry of hafnium dioxide (known as hafina) is rather boring. Yet, the behavior of ultrathin layers that are based on this material is very interesting: they can be used as non-volatile computer memory through the ...

Conifer needles found to consume oxygen when times are hard

Plants give us oxygen through photosynthesis—this is commonly taught in school. An international research team has now shown that, particularly in early spring when low temperatures coincide with high light, conifer needles ...

Without ozone, the Earth might get a lot colder

The evolution of Earth's climate contains many components. And new research has shown just how critical the ozone layer is to the surface temperature of the Earth. Without an ozone layer, our planet would be 3.5 Kelvin cooler.

Intentional defects make for better reactions, researchers report

A defect is not always a bad thing. In fact, when it comes to improving the electrocatalysis process that produces clean-burning hydrogen gas, it may be a very good thing. Researchers based in China engineered an electrocatalyst—which ...
