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 ...
Multicolor meta-hologram produces light across entire visible spectrum
Within colors of bees and butterflies, an optical engineer's dream is realized
Evolution has created in bees, butterflies, and beetles something optical engineers have been struggling to achieve for years—precisely organized biophotonic crystals that can be used to improve solar cells, ...
CLAIRE brings electron microscopy to soft materials
Soft matter encompasses a broad swath of materials, including liquids, polymers, gels, foam and - most importantly - biomolecules. At the heart of soft materials, governing their overall properties and capabilities, ...
Adding transparency to graphene paper improves supercapacitor capacitance
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 ...
One-nm-thick graphene engine mimics two-stroke engine
Super-insulated clothing could eliminate need for indoor heating
Pen draws flexible circuits using half-meter long carbon nanotube fibers
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.
