Most of us become so comfortable or used to our current situation that we don't really know how to escape from it. Don't be the victim of"Boiled frog" phenomenon。 我们很容易对现在所处的环境妥协,不要成为温水煮青蛙效应的受害者。 01 定义 A ...

Boiling begins when the liquid is heated to the point at which the pressure of the saturated vapor above its surface becomes equal to the external pressure. The temperature at which a liquid starts to boil under a constant pressure is called the boiling point (Tb). Strictly speaking, Tb ...
Boiling is a very complex phenomenon that involves nucleation, bubble growth, departure, rewetting of the heater surface, and the resulting mixing of the surrounding fluid. In this regard, flow boiling in microchannels has drawn significant interest due to the promise of efficient removal of high ...
By definition, the Boiling Point is the temperature at which the vapour pressure of the liquid equals the surrounding pressure, and the liquid turns into vapour. The phenomenon of boiling is pressure dependent and hence, the Boiling Point of a liquid may change depending upon the surrounding pres...
Interestingly, while the intensity level of sound increases with the increase in heat flux in the NB regime, the frequency signature remains intact in the audible frequency range (0–1 kHz), with a peak frequency in the range of 200–250 Hz, which is completely in line with the literature...

This doubling phenomenon is called Moore’s Law after Intel co-founder Gordon Moore, who observed the trend in 1965 and predicted it would continue for at least a decade. It held through the 2010s and has now begun to slow. That’s because transistor widths have shrunk to the atomic scale...
(b) Representative snapshots showing boiling phenomenon on the smooth substrate (top panel) and the nanopillar substrate having r = 3.2 (bottom panel) at several surface temperatures T. While the smooth surface produces vapour bubbles which have tendency to coalesce (e.g., at T = 74 °C)...
