Creating electricity with caged atoms
Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists ...
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
Researchers discover new material to produce clean energy
Researchers at the University of Houston have created a new thermoelectric material, intended to generate electric power from waste heat - from a vehicle tailpipe, for example, or an industrial smokestack ...
Researchers find tin selenide shows promise for efficiently converting waste heat into electrical energy
Getting more electricity out of solar cells
(Phys.org) —When sunlight shines on today's solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons—behavior ...
Researcher invents continuous, zero-toxic-emission system that converts nonrecycled plastics into crude oil
Plastic is becoming a major problem worldwide: In 2012, the United States alone produced roughly 32 million tons of plastic waste, while only recycling about 9 percent of its plastic, according to the Environmental ...
Thermoelectrics for waste-heat recovery: Introducing E1
Spintronic thermoelectric power generators: A step towards energy efficient electronic devices
(Phys.org) —Imagine a computer so efficient that it can recycle its own waste heat to produce electricity. While such an idea may seem far-fetched today, significant progress has already been made to realize ...
Students launch desktop recycler that turns pop bottles into 3D printer plastic
Three engineering physics students at the University of British Columbia have developed a desktop plastic recycler and extruder that turns plastic waste into the material needed for 3D printing.
Eight million tons: Researchers calculate the magnitude of plastic waste going into the ocean
A plastic grocery bag cartwheels down the beach until a gust of wind spins it into the ocean. In 192 coastal countries, this scenario plays out over and over again as discarded beverage bottles, food wrappers, ...
Britain's first poo-powered bus takes to the road
Britain's first bus powered entirely by human and food waste took to the road in Bristol on Thursday.
New tech could be "Mr. Fusion" for biofuel
A new technology from Argonne may remind viewers of Mr. Fusion of Back to the Future fame, only with a biofuel twist: put in your waste and out comes diesel fuel.
Robots may receive urine-powered artificial 'hearts'
Excess heat from air conditioners causes higher nighttime temperatures
(Phys.org) —A team of researchers from Arizona State University has found that releasing excess heat from air conditioners running during the night resulted in higher outside temperatures, worsening the ...
