Artificial light-harvesting method achieves 100% energy transfer efficiency
(PhysOrg.com) -- In an attempt to mimic the photosynthetic systems found in plants and some bacteria, scientists have taken a step toward developing an artificial light-harvesting system (LHS) that meets one of the crucial ...
Thermoelectric paint enables walls to convert heat into electricity
(Phys.org)—Paint these days is becoming much more than it used to be. Already researchers have developed photovoltaic paint, which can be used to make "paint-on solar cells" that capture the sun's energy and turn it into ...
Scientists propose quantum wells as high-power, easy-to-make energy harvesters
(Phys.org) —By collecting heat energy from the environment and transforming it into electrical power, thermoelectric energy harvesters have the potential to provide energy for a variety of small electronic devices. Currently, ...
Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
Ancient effect harnessed to produce electricity from waste heat
A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind ...
Quick jolt of energy could improve energy harvesting by a factor of 40
(PhysOrg.com) -- Harvesting mechanical energy from the environment and converting it into electrical energy has recently become a viable method for powering low-energy electronics, such as sensors and actuators. But the major ...
Students harness vibrations from wind for electricity
(PhysOrg.com) -- The Vibro-Wind Research Group is working on an efficient, low-cost method of converting vibrations from wind energy to electricity.
Hybrid energy harvester generates electricity from vibrations and sunlight
(Phys.org) —Devices that harvest energy from the environment require specific environmental conditions; for instance, solar cells and piezoelectric generators require sunlight and mechanical vibration, respectively. Since ...
Watching electrons cool in 30 quadrillionths of a second
Two University of California, Riverside assistant professors of physics are among a team of researchers that have developed a new way of seeing electrons cool off in an extremely short time period.
