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 …

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. …

A classical lens made of plastic or glass has a curved shape that bends the path of incoming light toward a single focal point on a piece of photographic film or an electronic sensor. This is because light travels faster through the thinner glass at the edges of the lens …

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 – …

The rapid increase in global energy consumption and the environmental impact of traditional energy resources pose serious challenges to human health, energy security, and the environment; and reveal a growing need to develop new types of clean and sustainable energy solutions  such as electric vehicles with low exhaust emissions. However the …

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. They are predicted to be able to protect the building from earthquakes by bending …
