Renaissance of the iron-air battery

Iron-air batteries promise a higher energy density than present-day lithium-ion batteries. Their main constituent, iron, is an abundant and cheap material. Scientists from Forschungszentrum Jülich are pursuing research into ...

How hot weather and climate change affect airline flights

Hot weather has forced dozens of commercial flights to be canceled at airports in the Southwest this summer. This flight-disrupting heat is a warning sign. Climate change is projected to have far-reaching repercussions – ...

New method increases energy density in lithium batteries

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method to increase the energy density of lithium (Li-ion) batteries. He has built a trilayer structure that ...

Greening cities reduces air pollution

A UTS research collaboration has provided the first experimental evidence that higher levels of urban forestry are associated with lower levels of air pollution, specifically the dangerous fine airborne particles, or particulate ...

Gravity waves and sunglint, lake superior

From the vantage point of the International Space Station, astronauts frequently observe atmospheric and surface phenomena in ways that are impossible to view from the ground. Two such phenomena—gravity waves and sunglint—are ...

What's the best design for a flying Mars robot?

Building a flying vehicle for Mars would have significant advantages for exploration of the surface. However, to date, all of our surface exploring vehicles and robotic units on Mars have been terrestrial rovers. The problem ...
