By applying specific voltages, the team has also shown that it can achieve this control over large and curved surface areas.”By changing the voltage applied to…
They have garnered attention as energy storage devices as they charge and discharge faster than batteries, yet they are still limited by low energy densities,…
Soft magnetic materials can be easily magnetized and demagnetized. They are widely used in microwave devices, such as absorption of electromagnetic radiations.Developers tend to use thin films of soft magnetic materials, as opposed to their bulk form, in mobile applications, such as cell phones and laptops, as well as military applications, such as stealth aircrafts. However, the conventional approach to making soft magnetic films requires a high vacuum environment, which is expensive and time-consuming. Moreover, the usual fabrication system is not suitable for the preparation of large sheet films, thereby limiting its application in manufacturing the soft magnetic materials for microwave absorption….
