Carbon dioxide reveals a predilection for tumbling alone and lining up together
(Phys.org)—Crowded together on a titanium dioxide surface, carbon dioxide molecules relinquish their free-tumbling ways to form crooked lines and cling to molecules in nearby lines, according to scientists ...
Improved performance for solar cells: Highly efficient p-type dye-sensitized solar cell with cobalt-based electrolyte
(Phys.org)—Photovoltaics continues to be an expensive technology. Dye-based solar cells may represent a more cost-effective alternative to traditional solar cells. In these cells, a dye is used in place ...
The self-improvement of lithium-ion batteries
(Phys.org)—The search for clean and green energy in the 21st century requires a better and more efficient battery technology. The key to attaining that goal may lie in designing and building batteries not ...
Nanoparticles: A greater danger to the environment than previously thought
Nanoparticles are more harmful to small animals than tests have indicated to date. This has been shown in a new study of the University of Koblenz-Landau. Thus, the offspring of water fleas (Daphnia magna) ...
Hypergravity helping aircraft fly further
(Phys.org)—ESA research has helped to develop an aircraft-grade alloy that is twice as light as conventional nickel superalloys while offering equally good properties. The path to creating this alloy required ...
Researchers make strides toward selective oxidation catalysts
Oxide catalysts, typically formulated as powders, play an integral role in many chemical transformations, including cleaning wastewater, curbing tailpipe emissions, and synthesizing most consumer products.
Next-generation antireflection coatings could improve solar photovoltaic cell efficiency
Photovoltaic cell efficiency may soon get a big boost, thanks to next-generation antireflection coatings crafted from nanomaterials capable of cutting down on the amount of light reflected away from a cell's surface.
Radioactive decay of titanium powers supernova remnant
(Phys.org)—The first direct detection of radioactive titanium associated with supernova remnant 1987A has been made by ESA's Integral space observatory. The radioactive decay has likely been powering the ...
Cost-effective titanium forming
Titanium is a material that offers excellent properties; however, it is costly and time-consuming to form. Fraunhofer researchers are now giving this multi-purpose metal another chance.
'Superstructured' solar cells achieve record efficiency of 10.9%
Scientists battle harmful water toxins
University of Ulster scientists are collaborating with international research partners to develop a new 'clean' technology to destroy water toxins caused by harmful algal blooms.
Buildings may soon be able to generate their own electricity from roofs, walls, windows – even benchtops – that come with in-built solar power capabilities.
Pollution-busting laundry additive gets set to clean up
Within just two years, we could all be wearing clothes that purify the air as we simply move around in them.
A windshield wiper for Mars dust developed
A team of researchers at Universidad Carlos III in Madrid has developed a device that works as a windshield wiper to eliminate Mars dust from the sensors on the NASA spacecrafts that travel to the red planet.
