Study reveals extreme winter weather is related to Arctic change

A new study shows that the frequency of polar vortex disruptions that is most favorable for extreme winter weather in the United States is increasing, and that Arctic change is likely contributing to the increasing trend. ...

How to help your pandemic puppy avoid doggy distress

Many people are living on pandemic time. Before COVID and after COVID, in other words. And the post-pandemic world is rapidly changing as more people get vaccinated. Students are going back to school, parents are going back ...

Perovskites under pressure: Hot electrons cool faster

In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...

Challenges in the development of electrocatalysts

Regenerative energy harvesting often generates more electricity than is directly needed. Electrochemical processes could be used to store the excess energy or make it usable. Although intensive research on the catalysts required ...

Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

Hot electrons harvested without tricks

Semiconductors convert energy from photons (light) into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce "hot electrons," and the excess energy of these electrons ...
