Anti-counterfeit 'fingerprints' made from silver nanowires
Unique patterns made from tiny, randomly scattered silver nanowires have been created by a group of researchers from South Korea in an attempt to authenticate goods and tackle the growing problem of counterfeiting.
Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
In latest generation of tiny biosensors, size isn't everything
(Phys.org) —When it comes to nanomedicine, smaller is—surprisingly—not always better.
Better solar cells, better LED light and vast optical possibilities
Changes at the atom level in nanowires offer vast possibilities for improvement of solar cells and LED light. NTNU-researchers have discovered that by tuning a small strain on single nanowires they can become ...
