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 …

The phonon is the physical particle representing mechanical vibration and is responsible for the transmission of everyday sound and heat. Understanding and controlling the phononic properties of materials provides opportunities to thermally insulate buildings, reduce environmental noise, transform waste heat into electricity and develop earthquake protection.   The concept of …

Normal solid surfaces are wetted by liquids such as water and oil. In many cases, surface wetting is undesirable due to the fact that the liquids may largely deteriorate the functionality of the surface, or cause unwanted effects. For example, evaporation of liquid droplets could leave behind chemical or dirt …

After nearly a century of dominance as the material of choice for aircraft, metals are seeing increased competition from composite materials in use on Aircrafts. In the modern age, the aerospace industry is also looking ahead to tougher, lighter, and more heat-resistant materials that would lessen emissions, cut fuel costs, …

Norwegian oil and gas industry is heading into the Arctic, and its looking for Work clothing specifically tailored to Arctic conditions is hard to find. Industrial designers have now joined forces with researchers to create the perfect clothing concept. Wenaas is a leading supplier of work clothing to the oil …

Neuro- or Biohybrid systems are systems formed by at least one biological component – i.e. already existing in living systems – and at least one artificial – newly engineered – component. Biological and artificial components are not independent but are passing information either in one or both directions, thereby forming …

A metal foam is a cellular structure consisting of a solid metal (frequently aluminium) with gas-filled pores comprising a large portion of the volume. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam). The defining characteristic of metal foams is a high porosity: typically only 5–25% of the …

In quantum mechanics, spin is an intrinsic form of angular momentum carried by elementary particles. Spintronics is “A branch of physics concerned with the storage and transfer of information by means of electron spins in addition to electron charge as in conventional electronics.” Spin-based electronics focuses on devices whose functionality …

Finding new materials has traditionally been guided by intuition and trial and error,” said Turab Lookman, a physicist and materials scientist in the Physics of Condensed Matter and Complex Systems group at Los Alamos National Laboratory. “But with increasing chemical complexity, the combination possibilities become too large for trial-and-error approaches …
