Researchers have designed a device that uses light to manipulate its mechanical properties. The device, which was fabricated using a plasmomechanical metamaterial, operates through a unique mechanism that couples its optical and mechanical resonances, enabling it to oscillate indefinitely using energy absorbed from light.
Researchers have discovered how to subtly change the interior structure of semi-hollow nanorods in a way that alters how they interact with light, and because the changes are reversible, the method could form the basis of a nanoscale switch with enormous potential.
Scientists have developed a multi-layered 'sensing skin' to detect corrosive or otherwise harmful substances in structures. The skin can also detect cracks and other structural flaws that are invisible to the naked eye.
Researchers have developed methods to control defects in two-dimensional materials, such as graphene, that may lead to improved membranes for water desalination, energy storage, sensing or advanced protective coatings.
An international collaboration has discovered a new method to inscribe exotic magnetic patterns such as magnetic monopoles into thin ferromagnetic films. Such unconventional orientation of magnetic domains might open a new path for the design of energy efficient data storage.
A new tool that uses a forest-like array of vertically-aligned carbon nanotubes that can be finely tuned to selectively trap viruses by their size can increase the detection threshold for viruses and speed the process of identifying newly-emerging viruses.
Engineers have developed an innovative bio-manufacturing process that uses a biological organism cultivated in brewery wastewater to create the nanostructured carbon-based materials needed to make energy storage cells.
The process of photosynthesis, through which plants convert sunlight into chemical energy, involves a carefully choreographed transfer of energy from molecule to molecule. Exactly how the energy is moved is not fully understood, as it is extremely difficult to observe these transfers, which take place extremely rapidly and on a very small scale.
A study offers evidence that small morphological changes can lead to large changes in function. The gecko adhesive apparatus, one of the most spectacular innovations displayed by vertebrates, has been intensively studied for the last 16 years and is of considerable interest to nanotechnologists and biomimeticists.
