Turn that defect upside down: Twin boundaries in lithium-ion batteries
Most people see defects as flaws. A few Michigan Technological University researchers, however, see them as opportunities. Twin boundaries—which are small, symmetrical defects in materials—may present ...
Researchers find a way of tuning light waves by pairing two exotic 2-D materials
Researchers have found a way to couple the properties of different two-dimensional materials to provide an exceptional degree of control over light waves. They say this has the potential to lead to new kinds ...
Plugging up leaky graphene: New technique may enable faster, more durable water filters
For faster, longer-lasting water filters, some scientists are looking to graphene —thin, strong sheets of carbon—to serve as ultrathin membranes, filtering out contaminants to quickly purify high volumes ...
Theorists show environments can alter 2-D materials' basic properties
What if peanut brittle, under certain conditions, behaved like taffy? Something like that happens to a two-dimensional dichalcogenide analyzed by scientists at Rice University.
Graphene-based technique creates the smallest gaps in nanostructures
A new procedure will enable researchers to fabricate smaller, faster, and more powerful nanoscale devices ─ and do so with molecular control and precision. Using a single layer of carbon atoms, or graphene, ...
Charged holes in graphene increase energy storage capacity
Engineers at the University of California, San Diego have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research, published ...
Erupting electrodes: How recharging leaves behind microscopic debris inside batteries (w/ Video)
An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body, and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise.
