Multiferroic materials exhibit both ferromagnetism and ferroelectricity. These are expected to be used as multiple-state memory devices. Furthermore, if the two orders are strongly coupled and the magnetization can be reversed by applying an external electric field, the material should work as a form of low power consumption magnetic memory.
Scientists have modeled how a colloidal droplet evaporates and found a previously overlooked mechanism that more accurately determines the dynamics of particle deposition in evaporating sessile droplets, which has ramifications in many fields of today's technological world.
Nanotechnology offers many chances to benefit the environment and health. It can be applied to save raw materials and energy, develop enhanced solar cells and more efficient rechargeable batteries and replace harmful substances with eco-compatible solutions.
Researchers have captured the formation of a platinum encrusted nanoparticle that bears a striking resemblance to a festive snowman. As well as providing some Christmas cheer, the fully functional 'nano-snowman' has applications for providing greener energy and for advancements in medical care.
Processors and storage media making use of tiny structures called 'skyrmions' could one day lead to the further miniaturization of IT devices and improve their energy efficiency significantly.Physicists have now put forward a method which could speed up the screening of suitable materials.
Scientists have uncovered the underlying equation governing the carrier's transport across the graphene/semiconductor Schottky junction, which is one of the building blocks in electronic and optoelectronic devices.
Scientists are taking a synthetic approach to muscle regeneration. Their goal is to create a synthetic, porous, biologically compatible 'scaffold' that mimics the normal extracellular environment of skeletal muscle - onto which human cells could migrate and grow new replacement fibers.
Scientists have developed a novel method for delivering therapeutic molecules into cells. The method harnesses gold nanoparticles that are electrically activated, causing them to oscillate and bore holes in cells' outer membranes and allowing key molecules - such as DNA, RNA, and proteins - to gain entry.
