Solving molybdenum disulfide's 'thin' problem
The promising new material molybdenum disulfide (MoS2) has an inherent issue that's steeped in irony. The material's greatest asset—its monolayer thickness—is also its biggest challenge.
ORNL microscopy directly images problematic lithium dendrites in batteries
Scientists at the Department of Energy's Oak Ridge National Laboratory have captured the first real-time nanoscale images of lithium dendrite structures known to degrade lithium-ion batteries. The ORNL team's ...
Hybrid nanowires eyed for computers, flexible displays
A new process for coating copper nanowires with graphene - an ultrathin layer of carbon – lowers resistance and heating, suggesting potential applications in computer chips and flexible displays.
Sweet nanoparticles target stroke
Materials resulting from chemical bonding of glucosamine, a type of sugar, with fullerenes, kind of nanoparticles known as buckyballs, might help to reduce cell damage and inflammation occurring after stroke. ...
New device takes images of lithium battery as it works and recharges
Used in everything from electric vehicles to laptop computers, the lithium battery is ubiquitous, but it is not well understood at the atomic scale. To see what happens on the nanoscale, scientists at DOE's ...
Chemists make new silicon-based nanomaterials
Chemists from Brown University have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon.
Peering into how rechargeable lithium ion batteries function
Nanoparticle electrodes in lithium-ion batteries have both near-surface and interior contributions to their redox capacity, each with distinct rate capabilities. Using combined electron microscopy, synchrotron ...
