(Phys.org) -- As their name suggests, Li-air batteries use air to operate, pulling out oxygen molecules to use in a porous, carbon-based cathode, while using lithium in the anode. Because using air means the battery doesn’t ...
Chemists at UCL have discovered a new property of flames, which allows them to control reactions at a solid surface in a flame and opens up a whole new field of chemical innovation.
Soft magnetic materials can be easily magnetized and demagnetized. They are widely used in microwave devices, such as absorption of electromagnetic radiations.
(PhysOrg.com) -- Recently, researchers have been designing a wide variety of self-propelled micromotors, many of which operate using an oxygen-bubble propulsion mechanism that requires a high concentration of hydrogen peroxide ...
Purdue University scientists have developed a method for stacking synthetic DNA and carbon nanotubes onto a biosensor electrode, a development that may lead to more accurate measurements for research related to diabetes and ...
(PhysOrg.com) -- Measuring just 3.6 micrometers long, one of the smallest batteries ever made won’t be powering our electronic devices anytime soon, but it does serve as a self-powered nanomotor that is surprisingly ...
Transforming solar energy into a usable form is a real challenge. One technique is to use semiconductors to store the energy as hydrogen. Unfortunately, the most efficient semiconductors are not the most stable. An Ecole ...
Monitoring everything from explosives to tainted milk, materials for use in creating sensors for detection devices have been developed by a University of Houston (UH) chemist and his team. The findings recently appeared simultaneously ...
(PhysOrg.com) -- Rice University researchers have moved a step closer to creating robust, three-dimensional microbatteries that would charge faster and hold other advantages over conventional lithium-ion batteries. They could ...
Researchers have made an important breakthrough in the use of continuous flow microreactors to produce thin film absorbers for solar cells - an innovative technology that could significantly reduce the cost of solar energy ...
