Electron Microscope Tomography and Single-particle Reconstruction

2.4K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Porosity in Cement Paste01:18

Porosity in Cement Paste

140
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
The balance of water to cement in the mix is...

Area of Science:

  • Materials Science
  • Civil Engineering
  • Aerospace Engineering

Background:

  • In-situ resource utilization is key for sustainable extraterrestrial construction.
  • Traditional material transport to space is cost-prohibitive.
  • Cementitious materials are essential for building structures beyond Earth.

Purpose of the Study:

  • To develop a novel methodology for reconstructing cementitious microstructures hydrated in microgravity.
  • To utilize deep learning for generating statistically representative microstructures from limited experimental data.
  • To enable accurate characterization of materials for space applications.

Main Methods:

  • Scanning Electron Microscopy (SEM) was used to capture micrographs of hardened tri-calcium silicate (C3S) samples hydrated in microgravity.
  • A deep learning framework was employed to reconstruct 3D microstructural volumes from 2D SEM exemplars.
  • Statistical descriptors and micro-CT data were used for validation of reconstructed volumes.

Main Results:

  • The deep learning framework successfully generated an ensemble of statistically relevant microstructures.
  • Space-hydrated C3S samples exhibited significantly higher porosity (~70%) and elongated portlandite morphology.
  • Reconstructed volumes accurately captured the microstructural characteristics of both space-returned and ground-based samples.

Conclusions:

  • The developed reconstruction method effectively models microstructures from sparse extraterrestrial data.
  • The findings provide a pathway for characterizing mechanical and transport properties of space-based construction materials.
  • This research supports the development of advanced materials for long-term human presence in space.
