Preparation of Samples for Electron Microscopy

Preparation of Samples for Electron Microscopy

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...

Background:

Miniaturized electronics require smart, flexible electromagnetic interference (EMI) shielding materials.
Existing switchable EMI shielding materials often rely on explicit structural changes.

Purpose of the Study:

To develop a novel switchable MXene coating film with inner implicit structural change for EMI shielding.
To utilize reversible large-cavity yolk-shell biomicrospheres for tunable shielding properties.

Main Methods:

Fabrication of novel yolk-shell biomicrospheres with a PNIPAM hydrogel core, switchable cavity, and p-PDA shell.
Integration of biomicrospheres into a MXene framework to create a WR-MXene coating film.
Characterization of the switchable shielding performance in the X band.

Main Results:

The WR-MXene coating film exhibits an ultralight and flexible nature.
Achieved a large switchable change of over 60 dB in EMI shielding.
Demonstrated extraordinary EMI shielding effectiveness, reaching 95 dB and over 50 dB in the X band.

Conclusions:

The developed succulent-inspired switchable coating films offer promising solutions for smart flexible wearable devices.
The novel reversible yolk-shell biomicrospheres enable dynamic real-time response in multifunctional systems.
This approach provides a new pathway for advanced EMI shielding materials with tunable properties.
