Biphilic surfaces reduce defrosting times in heat exchangers

Ice formation and accumulation are challenging concerns for several industrial applications including heating ventilation air conditioning and refrigeration (HVAC&R) systems, aircraft, energy transmission, and transportation ...

Ammonia for fuel cells

Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient ...

Improving geothermal HVAC systems with mathematics

Extreme weather events, water shortages, and other consequences of climate change have challenged—and compromised—energy infrastructure around the world. Increased energy consumption is threatening the longevity of a ...

A lung-inspired design turns water into fuel

Scientists at Stanford University have designed an electrocatalytic mechanism that works like a mammalian lung to convert water into fuel. Their research, published December 20 in the journal Joule, could help existing clean ...

Algae could be a new green power source

As world leaders prepare to gather in France for the 2015 United Nations Conference on Climate Change next week, global warming—and how to stop it—is a hot topic.
