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 …

Radiation in a high-frequency circuit or system can be difficult to control. For that reason, RF/microwave absorber materials are often added to circuits to suppress or eliminate unwanted radiation either from the circuit to the outside or to minimize the effects of radiated signals outside a circuit (such as broadcast …
