TLDR
In this paper, a brief review of the mechanisms that may be responsible for delayed nucleation and examines the limited literature on incipience superheat excursions is presented. But the authors do not consider the effect of temperature variations on the nucleation of microelectronic components.
Abstract
Many of the candidate fluids for immersion cooling of microelectronic components possess both low surface tension and high gas solubility. As a consequence, ebullient heat transfer with such fluids is accompanied by nucleation anomalies and a frequently observed wall temperature overshoot. The difficulty in preventing this thermal excursion and in predicting its magnitude constrains the development of immersion cooling systems. This paper begins with a brief review of the mechanisms that may be responsible for delayed nucleation and examines the limited literature on incipience superheat excursions.

Multi-fluid subdued boiling; theoretical analysis of multi-fluid interface bubbles

TL;DR: The recently discovered boiling phenomenon called "multi-fluid subdued boiling" is discussed in this article, where it has been observed that when a beaker containing two immiscible liquids of dissimilar densities is heated at the bottom, the vapobr ubbles rise in the lower liquid until they reach the liquid-liquid interface.
