Phases and Phase Changes of Clusters

1996
Phase-like forms are expected to be observable for many kinds of clusters, insofar as they should satisfy criteria used to characterize phases of bulk form. However clusters are also expected to exhibit phase-like forms that do not have direct counterparts in bulk matter, and the equilibrium and transformations among these forms can be quite different ...

Change of Phase in the Psychoses [PDF]

open access: possibleJournal of Mental Science, 1922
Change of phase is a well-recognised feature in the course of certain of the psychoses. In manic-depressive insanity it is on the phasic variation of the affective state that the separation of that type of mental disorder is based. So, also, in many cases of the chronic psychoses phase changes occur as the disorder progresses, and as the patient fits ...

Phase change memory

Science China Information Sciences, 2011
Phase change memory (PCM) is a non-volatile solid-state memory technology based on the large resistivity contrast between the amorphous and crystalline states in phase change materials. We present the physics behind this large resistivity contrast and describe how it is being exploited to create high density PCM.

Convection with phase change

1975
Convection processes with phase change are of great importance, particularly those involving boiling and condensing in the fluid phase. Such processes occur in steam power plant and in chemical engineering plant. Convection in the liquid to solid phase change is also of importance, as for example in metallurgical processes, but this cannot be ...

Kinetics of Phase Change. II Transformation‐Time Relations for Random Distribution of Nuclei

, 1940
Following upon the general theory in Part I, a considerable simplification is here introduced in the treatment of the case where the grain centers of the new phase are randomly distributed. Also, the kinetics of the main types of crystalline growth, such

Phase Change Memory

2008 International Interconnect Technology Conference, 2008
This paper will give an introduction to the emerging technology of Phase Change Memory (PCM) and review the state of the art, focusing on basic phase change material properties, critical PCM device characteristics, PCM device scaling, reliability issues, and processing challenges.

Change of phase

1983
Systems of more than one phase When a system consists of more than one phase, each phase may be considered as a separate system within the whole. The thermodynamic parameters of the whole system may then be constructed out of those of the component phases.
