In 1911, a Dutch scientist discovered a class of materials which, at temperatures near absolute zero, could conduct electricity with no resistance and therefore zero loss of power. These materials called Superconductors have unique properties including, Zero resistance to direct current;  Extremely high current carrying density; Extremely low resistance at …

The piezoelectric effect was discovered by brothers Pierre and Jacques Curie in 1880, and named after the Greek word piezein, that means to press or squeeze. They found that certain crystals were able to generate an electrical charge when mechanically loaded with tension or pressure. If exposed to an electric …

The need for more energy-efficient computers is urgent. The Department of Energy projects that, with the computer chip industry expected to expand to several trillion dollars in the next few decades, energy use by computers could skyrocket from 3 percent of all U.S. energy consumption today to 20 percent, nearly …

REEs are a series of chemical elements found in the Earth’s crust that are essential components of many technologies, including electronics, computer and communication systems, transportation, health care, and national defense. Rare Earths Elements (REE) are incorporated into many sophisticated technologies with both commercial and defense applications including smartphones and …

Today, silicon microchips underlie every aspect of digital computing. Now Moore’s Law is stuttering, and the world’s supercomputer builders are confronting an energy crisis. But those big gains using silicon seem to have ended, with the high-end Intel Core i7 chips, for instance, have been on computer store shelves for …

High speed Supercomputers enable advanced computational modeling and data analytics applicable to all areas of science and engineering. They are being widely used in applications like Astrophysics, to understand stellar structure, planetary formation, galactic evolution and other interactions; Material Sciences to understand the structure and properties of materials and creation …

Plasma is a state of super excitement of mater and can be described as a super hot gas. The Plasma Spray Process is basically the spraying of molten or heat softened material onto a surface to provide a coating. Plasma spray is a versatile technology used for production of environmental …

Perovskites have generated huge interest in recent years because of their potential for solid-state lighting and displays, despite lagging behind other state-of-the-art technologies in efficiency and longevity. Now two independent teams have reported light-emitting diodes (LEDs) based on perovskites that have surpassed a milestone in efficiency [Cao et al., Nature …

Over the past two decades, many wireless systems have been developed and widely used around the world. The most important examples are cellular mobile radio and Wi-Fi systems. Just like radio and television broadcasting systems, they radiate electromagnetic waves/energy into the air but a large amount of the energy is …
