TL;DR: As-synthesized iron oxide nanoparticles have a cubic spinel structure as characterized by HRTEM, SAED, and XRD and can be transformed into hydrophilic ones by adding bipolar surfactants, and aqueous nanoparticle dispersion is readily made.

TL;DR: This work discusses the critical aspects that may affect the scaling of PCRAM, including materials properties, power consumption during programming and read operations, thermal cross-talk between memory cells, and failure mechanisms, and discusses experiments that directly address the scaling properties of the phase-change materials themselves.

TL;DR: In this article, the authors survey the current state of phase change memory (PCM), a nonvolatile solid-state memory technology built around the large electrical contrast between the highly resistive amorphous and highly conductive crystalline states in so-called phase change materials.

TL;DR: Phase change materials are materials that exist in at least two structurally distinct solid phases, an amorphous and one (or more) crystalline phases that can be used to store information in technological applications if it is possible to switch the material repeatedly between the two phases and if both phases are stable at operating temperature.

TL;DR: The advantages and challenges of PCM are described, the physical properties of phase change materials that enable data storage aredescribed, and the current knowledge of the phase change processes is summarized.
