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, nanoengineers ...
Small electric voltage alters conductivity in key materials
Modern research has found no simple, inexpensive way to alter a material's thermal conductivity at room temperature.
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 recently online ...
Major advance in artificial photosynthesis poses win/win for the environment
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered ...
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.
Scientists visualize potential brain cancer treatments in real time with nanotechnology
Virginia Tech Carilion Research Institute scientists have developed new imaging techniques to watch dangerous brain tumor cells respond to treatment in real time.
Scientists program the lifetime of self-assembled nanostructures
Materials that self-assemble and self-destruct once their work is done are highly advantageous for a number of applications – as components in temporary data storage systems or for medical devices. For example, such materials ...
Water makes wires even more nano: Lab extends meniscus-mask process to make sub-10 nanometer paths
Water is the key component in a Rice University process to reliably create patterns of metallic and semiconducting wires less than 10 nanometers wide.
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.
