New material could make renewable energy from water, shows study

One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers at Linköping University, Sweden, have developed a...

Scientists find simpler way to massively produce perovskite solar cells

A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy...

Scientists find better material to improve supercapacitors

A sustainable, powerful micro-supercapacitor may be on the horizon. Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their...

How to prevent short-circuiting in next-gen lithium batteries

As researchers push the boundaries of battery design, seeking to pack ever greater amounts of power and energy into a given amount of space...

Scientists improve the energy efficiency of wearable health device

NC State's flexible heat harvesting device shows better efficiency at retaining heat to power the device. Engineers continue to improve the efficiency of a flexible...

Icing could cost wind turbines 80% of power production, shows study

Wind turbine blades spinning through cold, wet conditions can collect ice nearly a foot thick on the yard-wide tips of their blades. That disrupts blade...

Fuel efficiency of one car may be cancelled by your next car purchase

In a recent study, researchers find that consumers tend to buy something less fuel efficient than they normally would for their second car after...

Scientists boost efficiency of next-generation solar cell material to 25%

Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing...

Weakness is strength for this low-temperature battery

Scientists Diego have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte...

New study could help make hydrogen useful, sustainable fuel

Hydrogen is an incredibly powerful fuel, and the ingredients are everywhere—in plain old water. Researchers would love to be able to use it widely as...
