One way to produce clean water is to heat dirty water until it turns into steam. As the steam rises, it leaves behind the heavier contaminants and can be collected and cooled, providing clean water. There are many ways to ...
(Phys.org)—Researchers have used a simple inkjet printer to print a "bio-ink" of cyanobacteria onto a conductive surface, creating a biophotovoltaic cell. Unlike conventional photovoltaic cells that operate only when exposed ...
(Phys.org)—Researchers have turned to cicada wings to design surfaces with highly antireflective properties, which have potential applications for solar cells, stealth surfaces, antifogging materials, and other optical ...
(Phys.org) —As the world's dependence on fossil fuels causes ever-increasing problems, researchers are investigating solar fuels as an alternative energy source. To make solar fuels, sunlight is converted into hydrogen ...
It has often been said that solar cells are like artificial versions of the photosynthetic apparatuses found in plants, such as leaves, since both harvest sunlight. But nature's leaves can do something that most solar cells ...
(Phys.org) —The ability to guide, bend and focus light at the nanoscale is a highly sought-after goal in the field of nano-optics. Precise and efficient light control has direct applications in solar cells, holography, ...
(Phys.org) —Most batteries, supercapacitors, and other energy storage devices are based on a sandwich structure, where two electrodes face each other and the charge flows between them. However, when these structures are ...
(Phys.org)—Scientists have discovered that a solar cell consisting of two or three layers of quantum dots, with each layer tuned to a different part of the solar spectrum, has an efficiency that is 40-60% higher than the ...
(Phys.org)—As 2012 comes to a close, scientists and engineers are looking forward to molding the future, starting with the work they do in their own labs. Phys.org has interviewed a few of today's leading researchers in ...
(Phys.org)—Accurately determining the relative percentages of the elements comprising the Earth's core and mantle which formed early – that is, within 30 Ma (megaannum, or million years) after the solar system itself ...
