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.
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.
