It is estimated that around four billion people on the globe suffer from water scarcity. Distribution and production of fresh water and the control over water sources are potential cause for conflicts. Therefore, researchers are investigating new ways of freshwater production and the improvement of existing techniques.   Potable water …

Integrated circuits and power devices utilized by the semiconductor industry for the production of advanced computers, consumer electronics, communication networks, and industrial and military systems have been almost exclusively based on silicon technology. The requirements of future electronics place a great emphasis on achieving new devices with greater power density …

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 …

A new  power revolution is going on in orbit – that of electrical propulsion for satellites. An ion thruster is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions with electricity. As the ionised particles escape from the aircraft, they generate a force moving …

Ethylene is a hidden organic chemical that is crucial to modern human life. It is hidden because it is a precursor to products used in most households worldwide but not sold directly to consumers. For example, ethylene is the chemical base for polyethylene (PET) bottles, car parts, buckets, pipes, and …

Additive manufacturing (AM), broadly known as 3D printing, is transforming how products are designed, produced, and serviced. AM enables on-demand production without dedicated equipment or tooling, unlocks digital design tools, and offers breakthrough performance and unparalleled flexibility across industries.   Metal 3D printing is considered the apex of all 3D …

The era of hypersonic flight had arrived. Countries are developing future hypersonic Spaceplanes , enabling  intercontinental travel at very high speeds, that could  cut the journey times from the UK to Australia from the current duration of around 20 hours to as little as two hours.  They shall also provide …

Stealth technology has proven to be one of the effective approaches to enhance the survivability of Aircrafts. Aircraft/helicopter designers are making them stealthier by reducing their signatures; viz. visual, aural, infrared (IR), and RADAR cross section. Advancements in stealth technologies, as demonstrated by the very low RCS of stealth aircraft …
