The iron Fe2+ atom embedded in a semiconductor exhibits a single non-degenerate ground state of zero magnetic moment. A team of scientistss has just shown that by using sufficiently large strain it is possible to tailor the energy spectrum of the iron atom to obtain doubly degenerate (magnetic) ground state.
Super-sharp images from within the human body made through tiny endoscopes have come a step closer to reality. An advanced wavefront shaping method combined with unique optical fibres make it possible to focus lensless light at an unparalleled resolution.
New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a potential leap in performance.
The complement system, the human body's first line of defense against blood-borne intruders, is blamed for infusion-related reactions to nanomedicines, but the conventional models used to predict the risk of cardiopulmonary side effects in response to nanopharmaceuticals might not well represent what actually occurs in humans, according to a new article.
Among the candidates of next-generation memory devices, cross-bar-shaped non-volatile resistive memory (memristor) is one of the most attractive solutions for its non-volatility, faster access speed, ultra-high density and easier fabrication process.
