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 …

The amount of information trafficking internet nowadays is enormous and will increase further in the near future. It can be expected that in the next decennia the current technologies to store and process data will no longer suffice and that other strategies to handle information have to be developed. One …

Nanotechnology deals with the understanding, control, and manufacture of matter in the nanoscale regime, usually between 1 nm to 100 nm, and exploiting them for a useful application. At this length scale, unique properties and phenomena arise as a result of increased surface-to-volume ratio and dominance of quantum mechanical effects. …

In the past few years, metal halide perovskite quantum dots and nanocrystals have been extensively explored due to their unique optoelectronic properties and extensive application prospects. Perovskites are materials that share a crystal structure similar to the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3). Depending on which …

The ability to design and fabricate materials with new functionalities opens the door to a new world of possibilities. They can be tailored to either augment the functionality of existing devices or create new devices with superior performances. Metamaterials are artificially structured materials designed to control and manipulate physical phenomena …

An antenna is a device used to propagate, receive, and/or transmit electromagnetic waves which can have information embedded within them. The antenna creates an electromagnetic wave that carries the original embedded sound information through the atmosphere/space around it. An antenna at a different location, receives the electromagnetic wave, sending it …

Space-division multiplexing (SDM) has recently attracted great attention as a promising technology to further improve the transmission capacity and spectral efficiency. Very recently, SDM employing twisted lights, also known as orbital angular momentum (OAM) carrying lights, provides an alternative approach to increasing the transmission capacity and spectral efficiency of optical communications. …

Nanotechnologies involve designing and producing objects or structures at a very small scale, on the level of 100 nanometres (100 millionth of a millimetre) or less. It allows humans to play with the building blocks of the universe, exploiting the laws of quantum mechanics to construct materials with unimaginable precision – …
