Giant Enhancement in the Supercapacitance of NiFe–Graphene Nanocomposites Induced by a Magnetic Field

The development of supercapacitors holds great promise for future energy storage devices with a high cyclability and durability which can be used in our homes, cars and mobile phones to support the transition to sustainable energy. Even though a lot of effort has been devoted to improving the energy and power densities by optimizing the internal configuration of the capacitor, there is still room for further improvement. Now, researchers..

In-situ observation of Ge2Sb2Te5 crystallization at the passivated interface

In this work the DENSsolutions in situ TEM Lightning system has been employed to study the temperature induced nucleation behavior in Ge2Se2Te5 samples In Situ. This material is used as Phase Change Memory (PCM) and the knowledge of the amorphous-to-crystallize transition and the crystallization behavior is essential to its application, especially in nanometer or sub-nanometer modern and future electronics.
