University of Texas at Arlington chemists have developed new high-performing materials for cells that harness sunlight to split carbon dioxide and water into useable fuels like methanol and hydrogen...
View ArticlePhysicists promise a copper revolution in nanophotonics
Researchers from the Moscow Institute of Physics and Technology (MIPT) have for the first time experimentally demonstrated that copper nanophotonic components can operate successfully in photonic...
View ArticleBeyond invisibility—engineering light with metamaterials
Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten their sparkles. Today we are far more advanced in how we work with this...
View ArticleResearchers develop highly efficient hollow copper electrodes
Scientists at the University of Twente research institute MESA+ have developed an electrode in the form of a hollow porous copper fibre which is able to convert carbon dioxide (CO2) into carbon...
View ArticleEfficiency of water electrolysis doubled
Researchers have boosted the efficiency of water electrolysis. They applied a layer of copper atoms in a conventional platinum electrode. Thus, reaction intermediates could desorb a bit more easily...
View ArticleBacterial resistance to copper in the making for thousands of years
Human use of copper dating back to the Bronze Age has shaped the evolution of bacteria, leading to bugs that are highly resistant to the metal's antibacterial properties.
View ArticleNanocage surfaces get 'makeover' in room temperature
Kyoto University researchers have discovered a way of replacing surface ions of copper oxide nanocrystals at ambient conditions—a feat that will make nanocage production considerably simpler.
View ArticleCatalyst could make production of key chemical more eco-friendly
The world has more carbon dioxide than it needs, and a team of Brown University chemists has come up with a potential way to put some of it to good use.
View ArticleCopper sulfate found to be toxic to stingless bees
Copper sulfate has been used in agriculture since the 1800s, at least. In the U.S. it is widely used as a fungicide on organic and conventional crops, and it is also found in some fertilizer products.
View ArticleCombined effects of copper, climate change can be deadly for amphibians,...
Researchers at the University of Georgia's Savannah River Ecology Laboratory warn that the extinction to two amphibian species—the southern toad and the southern leopard frog—may be hastened by the...
View ArticleWill raindrops stick to a spider web's threads?
If you go out after a rain, you may notice spider webs glistening with water droplets. The soggy webs resemble human-made meshes for fog collection: They both have thin fibers that collect water from...
View ArticleCopper gives an answer to the rise of oxygen
A new study presents evidence that the rise of atmospheric oxygenation did indeed occur 2.4-2.1 billion years ago. It also shows that biological usage of copper became prominent after the so called...
View ArticlePreventing another Flint, Mich.; new research could lead to more...
With documented public water problems in Flint, Mich., and Hoosick Falls, N.Y., caused by corrosion, understanding how copper is affected at the atomic level is critical to avoiding problems in future...
View ArticleThe next generation of carbon monoxide nanosensors
The detection of carbon monoxide (CO) in the air is a vital issue, as CO is a poisonous gas and an environmental pollutant. CO typically derives from the incomplete combustion of carbon-based fuels,...
