Carbon nanotubes (CNTs) are hollow cylindrical tubes formed by rolling a sheet of carbon atoms arranged in a hexagonal ring, as in a sheet of graphite, either in monolayer (single-walled nanotube, SWCNT) or multilayer (multi-walled nanotube, MWCNT) form. CNTs exhibit different electronic properties based on the way these graphene …

Metamaterials are artificial materials designed to control the electromagnetic properties of a medium. Metasurfaces are the two-dimensional version of metamaterials: extremely thin surfaces made up of numerous subwavelength optical nanoantennas, each designed to serve a specific function upon the interaction with light. The metasurfaces contain regularly spaced nanoparticles that can …
Read More »Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

Quantum computing is expected to increase significantly the computational speed since it operates on completely different principles in comparison to classical computers. In addition, it was predicted that quantum computers can increase the computational speed of at least some problems. For instance, a sub-exponential speed-up is expected if the quantum …
Read More »With a view to future applications in electronics and quantum technology, researchers are focusing on the development of new components that consist of a single layer (monolayer) of a semiconducting material. Some naturally occurring materials with semiconducting properties feature monolayers of this kind, stacked to form a three-dimensional crystal. In …

Laser attacks targeting pilots and air crews are a major concern across the world with most attacks reported to take place during take-off and landing. According to figures from the US Federal Aviation Authority, there were 6,753 laser illuminations reported in 2017. Until recently, the expense of lasers had limited their use …

Microfluidic systems are any device that processes minuscule amounts of liquids. Microfluidics is the general term for the manipulation of nanoliter volumes of fluids through micro-channels. It deals with the behavior, precise control, and manipulation of fluids that are geometrically constrained to a small, typically sub-millimeter, scale. The fluids travel …
