Challenges, development and applications of microscale visualization techniques are discussed for the study of heating/evaporating thin films, gas bubble advancement in a microchannel, thermophoretic behavior near the solid surface, and microheater fabrications, mainly conducted at the Microscale Fluidics and Heat Transport Laboratory of Texas A&M University. The presented topics include:
  1. Fizeau interferometry for thin film thickness measurements.
  2. Total Internal Reflection Fluorescence Microscopy (TIRFM) for flow field measurements with 100-nm depth-of-field.
  3. Molecular Tagging Fluorescence Velocimetry (MTFV) using 10-nm caged seeding molecules.
  4. Ratiometric Laser Induced Fluorescence (LIF) for micro-resolution thermometry.
  5. Confocal Laser Scanning Microscopy (CLSM) for optical sectioning with 1.0-μm depthwise resolution.
  6. Multi-layer fabrications of microheater arrays with feedback circuit control.
Each of these techniques is discussed in three-fold: (1) its operating principle and operation, (2) its application and measurement results, and (3) its future challenges. PB Begell House LK https://www.dl.begellhouse.com/journals/52b74bd3689ab10b,2a88978d16ba1789,1b5a2da11afc4cf7.html
