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 …

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 …

As of May 2021, there are about 4,300 active artificial satellites currently orbit Earth. We rely so much on satellites for so many things in our lives, and we count on them to be durable and reliable. When satellites don’t work properly, they can severely impact our lives. That’s why …

Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidizer, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engines, rocket engines are the lightest and have the highest …

In 2018, The American Society of Mechanical Engineers (ASME)  named the Pratt & Whitney single crystal turbine blade an historic mechanical engineering landmark. These blades, which can be found in many modern, high-performance gas turbines (a.k.a. jet engines)—including the ones powering the F-22 Raptor, and larger electricity-producing turbines—are grown from a …

The COVID-19 pandemic, while demonstrating the nation’s vulnerabilities to biothreats, has also shown the fragility of the supply chain. The United States relies on foreign suppliers for a number of critical components including commodity chemicals, rare earth elements and active pharmaceutical ingredients, she said. Ensuring a resilient domestic supply chain …

The Department of Defense (DOD) acquires goods and services from contractors, federal arsenals, and shipyards to support military operations. The acquisition is a broad term that applies to more than just the purchase of an item or service; the acquisition process encompasses the design, engineering, construction, testing, deployment, sustainment, and …
