Using carbon composites with a porous structure to increase surface area and nanotubes to enhance conductivity, research demonstrates that these nanomaterials are able to catalyse oxygen reduction as efficiently as the state-of-the-art non-precious metal catalysts - and with a longer stability.
Researchers have shed new light on the mechanisms of thermal conductivity in graphene and other two-dimensional materials. They have demonstrated that heat propagates in the form of a wave, just like sound in air.
Researchers studied dendrite formation by using a miniature electrochemical cell that mimics the liquid conditions inside a lithium-ion battery. Placing the liquid cell in a scanning transmission electron microscope and applying voltage to the cell allowed the researchers to watch as lithium deposits grew into dendritic structures.
A developing form of computer memory has the potential to store information more quickly and more cheaply, while using less energy, than what's used today by the semiconductor industry, NYU Physics Professor Andrew Kent concludes.
A collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential for new technological devices ranging from computing to medicine.
Researchers have used an advanced model to simulate in unprecedented detail the workings of 'resistance-switching cells' that might replace conventional memory for electronics applications, with the potential to bring faster and higher capacity computer memory while consuming less energy.
The coating can be applied to clothes, paper, glass and steel and when combined with adhesives, maintains its self-cleaning properties after being wiped, scratched with a knife and scuffed with sandpaper.
Tiny, perfectly smooth carbon spheres added to motor oil have been shown to reduce friction and wear typically seen in engines by as much as 25 percent, suggesting a similar enhancement in fuel economy.
