(PhysOrg.com) -- One of the biggest challenges currently facing large-scale solar energy technology is finding an effective way to store the energy, which is essential for using the electricity at night or on cloudy days.
(Phys.org)—Researchers have fabricated a stretchable and transparent electrode that can be used for applications such as heating parts of the body and defrosting the side view mirrors on cars. It is the first stretchable ...
(PhysOrg.com) -- A new breed of rechargeable zinc-air batteries is soon to be available, and may replace lithium-ion batteries in cell phones, laptops and other consumer items. Lithium-ion batteries store only a third of ...
(PhysOrg.com) -- For many years, researchers have been working on designing and fabricating micro-air-vehicles (MAVs), flying robots the size of small insects. But after realizing how difficult it is to create a tiny, lightweight ...
Water is weird—and yet so important. In fact, it is one of the most unusual molecules on Earth. It boils at a temperature it shouldn't. It expands and floats when it is in the solid-state. Its surface tension is higher ...

(PhysOrg.com) -- When a river flows into the sea, the location is more than just a haven for water commerce. The mixing of fresh and salt water that occurs at an estuary also dissipates energy, as the different salinity waters ...
Research for many water scientists involves a frustrating paradox: Water purification requires prodigious amounts of electricity, while utilities guzzle huge volumes of water to generate electricity.
