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 …

Since the 1980’s, the electronics industry has undergone explosive growth, as higher transistor densities have fueled substantial performance advances while paving the way for miniaturization.  In order for these systems to function properly, the electronic circuits within them must be protected from extreme temperatures, contaminants, shock and vibration, and harsh …

Many alternatives to silicon are being developed, as it is believed that silicon transistors will reach their technological limits after 2020. Two-dimensional (2-D) nanomaterials have shown promise for a new generation of nanoelectronic devices. The most widely studied 2-D nanomaterial is graphene, a single layer of carbon atoms and packed …

Magneto resistor is a type of resistor whose resistance changes when an external magnetic field is applied. In other words, the flow of electric current through the magneto resistor changes when an external magnetic field is applied to it.   Magnetic field is the region present around a magnetic object …

“Electronics have dramatically changed the way we live, conduct business, communicate, and educate. Visions of the future foretell of ubiquitous computing and sensing. However, the environments in which electronics can reliably operate are limited. In consumer applications, typical operating temperatures range from -40° to 85°C. The “wider” military temperature range …
