Since the invention of nuclear power, there have been numerous “accidents.” From Three Mile Island and Chernobyl to the more recent problems in Fukushima, it would seem nuclear power is not fully under our control. Recently  a Chinese scientist  has warned that the single mountain under which North Korea most …

“The rapid evolution of small unmanned air systems (sUAS) technologies is fueling the exponential growth of the commercial drone sector, creating new asymmetric threats for warfighters. sUASs’ size and low cost enable novel concepts of employment that present challenges to current defense systems. These emerging irregular systems and concepts of …

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 …

A stealth ship is a type of ship which is especially used as a war vessel and is concealed from the navy vessels of other countries. It is an important warfare tactic that is used by nations wide across the world. Since they are invisible but the opposite navy vessels …

The primary function of the space propulsion system is to provide thrust, which helps in the functioning of the launch vehicle or satellite. In propulsion systems, the fluid (either solid, liquid, or electric) reacts to initiate acceleration and provide force in the system.   The use of electric propulsion (EP) …

Quantum technologies have the potential to spur revolutions in computing, sensing, cryptography and beyond. Quantum computing and quantum communication are believed to be the future of information technology.  Single-photon sources are important for current research in quantum information, cryptography, and the production of truly random numbers.   The possibility of …

Criminal activity continues to be a major concern in modern civilisations, with most nations facing unacceptable levels of crime and delinquency. The results show that African and Latin American countries suffer from the highest levels of various types of crime across the board, followed by countries in Asia. European, North American …

Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. Repair of certain materials during their lifecycle (especially those with structural functions such as concrete) can be very expensive and labour intensive.  Therefore Scientists began developing self-healing materials ,  those artificial (synthetic) substances that …
