A team led by 蘑菇视频 engineers has developed a new tool that could aid in the quest for better batteries and fuel cells. Although battery technology has come a long way since Alessandro Volta first stacked metal discs in a 鈥渧oltaic pile鈥� to generate electricity, major improvements are still needed to meet the energy challenges of the future, such as powering electric cars and storing renewable energy cheaply and efficiently. The key likely lies in the nanoscale, said…
蘑菇视频 researchers have shown that a favorable electrical property is present in a type of protein found in organs that repeatedly stretch and retract, such as the lungs, heart and arteries. These findings are the first that clearly track this phenomenon, called ferroelectricity, occurring at the molecular level in biological tissues.
Researchers found that a protein in organs that repeatedly stretch and retract can lose their functionality when exposed to sugar.
A paper in Science describes an organic crystal that shows promise as a cheap, flexible, nontoxic material for the working parts of memory chips, sensors and energy-harvesting devices.
