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 …

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 …

Motor vehicles also put a burden on society, especially in urban environments where they are chiefly responsible for noise and air pollution. Electric vehicles (EVs) have been considered as critical technology for …

The jet engine is the most complex element of an aircraft and one of the most complex human-made products ever developed, housing thousands of individual components — and ultimately determining fuel efficiency for aircraft All turbines operate on similar principles: A gas or other fluid turns a rotor, which …
Read More »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 …
