The system, which can be replenished by adding water, could help preserve food and pharmaceuticals especially in underdeveloped places.
Zapping catalysts with microwaves help them extract hydrogen from plastic waste and from water
Dynamic windows could do double duty in sustainable building design, cooling and powering at the same time.
Researchers found that just one cubic meter of seawater has the same cooling energy as a solar farm the size of 68 football fields—or 21 wind turbines.
Global paper consumption is rising, and recycling paper uses more fossil fuels than virgin paper. But a switch to renewable energy and better wastepaper disposal practices could drastically cut carbon emissions.
By chemically tweaking it with a natural plant extract, scientists have boosted the liquid-sopping ability of wheat gluten by over 10 times, making it a perfect sustainable absorbent material for diapers.
Putting solar farms on water has benefits, but coupling them with hydropower amps them up and could provide almost half of the world's electricity.
A supercapacitor made partly from from the plant polymer lignin is a step towards sustainable energy storage.
Thermocells are a low-cost technology to convert heat to electricity without moving parts, noise, or greenhouse gas emissions. Now researchers have found a way to make them efficient.
An ancient enzyme helps some land and freshwater bacteria produce a building block of plastic when they metabolize sulfur
