Interfacial phase-change memory

Nature Nanotechnology, 2011
Phase-change memory technology relies on the electrical and optical properties of certain materials changing substantially when the atomic structure of the material is altered by heating or some other excitation process. For example, switching the composite Ge(2)Sb(2)Te(5) (GST) alloy from its covalently bonded amorphous phase to its resonantly bonded ...

Stochastic phase-change neurons

Nature Nanotechnology, 2016
Artificial neuromorphic systems based on populations of spiking neurons are an indispensable tool in understanding the human brain and in constructing neuromimetic computational systems. To reach areal and power efficiencies comparable to those seen in biological systems, electroionics-based and phase-change-based memristive devices have been explored ...

Phase change enzyme immunoassay

Analytical Biochemistry, 1987
A novel enzyme-linked immunoassay employing a partitioning chromophore was developed. The assay system consisted of an aqueous phase and an immiscible organic solvent. Antigen-antibody interaction was indicated by transfer of a chromogenic indicator from the aqueous phase to an organic layer.

Phase Change Materials

2021
Apart from a purely scientific interest in molecular mixed crystals, the REALM continuously has been interested in finding applications—especially in the field of phase change materials for thermal protection and thermal energy storage. The key parameters are the heat of melting of the material and the thermal window, which is the temperature range in ...

Phase-change memory

ACM Computing Surveys, 2013
This article surveys the current state of phase-change memory (PCM) as a nonvolatile memory technology set to replace flash and DRAM in modern computerized systems. It has been researched and developed in the last decade, with researchers providing better architectural designs which address the technology's main challenges—its limited write endurance ...
