A new concept in energy harvesting could capture energy currently wasted due to its characteristic low frequency and use it to power next-generation electronic devices, according to a team of materials scientists and electrical engineers.
An inventory of research on hybrid organic-inorganic materials to date has revealed surprising new properties for these materials. The more their crystalline structure has defects, the greater their performance.
Researchers report that they have identified a unique 'breathprint' for each disease. Using this information, they have designed a device that screens breath samples to classify and diagnose several types of diseases.
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.
