Preparation of Samples for Electron Microscopy

5.3K
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...

Area of Science:

  • Materials Science
  • Surface Chemistry
  • Nanotechnology

Background:

  • Liquid metals (LMs) possess high surface tensions, hindering their practical applications.
  • Controlling LM wettability on diverse substrates and elucidating underlying mechanisms remain significant challenges.

Purpose of the Study:

  • To develop a facile dynamic-wetting strategy for modulating eutectic gallium-indium (EGaIn) wettability on polymer substrates.
  • To investigate the relationship between surface chemistry and EGaIn wetting behavior.
  • To assess the impact of enhanced wettability on thermal management performance.

Main Methods:

  • Chemical surface modification of polymer substrates.
  • Dynamic-wetting experiments to measure sliding angles and adhesion forces.
  • X-ray photoelectron spectroscopy (XPS) to analyze surface functional groups and chemical interactions.
  • Evaluation of heat transfer rates in EGaIn thermal management systems.

Main Results:

  • A stable, thin (∼18 μm) EGaIn layer spontaneously formed on modified surfaces.
  • Polymer substrate wetting behavior was categorized by sliding angles and adhesion forces.
  • Dynamic wetting occurred on surfaces with ≥18% oxygen-containing functional groups, indicating coordination interactions with the EGaIn oxide layer.
  • Heat transfer rates increased by up to 20% in the wetting group within EGaIn thermal management systems.

Conclusions:

  • The dynamic-wetting strategy effectively enhances EGaIn wettability on specific polymer surfaces.
  • Surface oxygen-containing functional groups are critical for achieving stable EGaIn wetting through coordination interactions.
  • Improved wettability significantly enhances thermal management efficiency, paving the way for LM applications in flexible electronics and thermal solutions.
