Pore Size Distribution

Pore Size Distribution

In concrete, the pore size distribution significantly influences the material's properties. Capillary pores, markedly larger than gel pores, form a vast network within partially hydrated cement paste, reducing the concrete's strength and increasing its permeability. This heightened permeability leads to a greater risk of damage from environmental factors like freeze-thaw cycles and chemical attacks, with the extent of vulnerability also being tied to the water-to-cement ratio.

Summary

Researchers explored how nanopore shape affects DNA translocation. They found that non-circular nanopores, like triangular ones, significantly alter ion flow, leading to a geometry-dependent ion scattering effect.

Background:

Solid-state nanopores lack precise geometric control compared to biological protein nanopores.
Experimentally formed solid-state nanopores typically exhibit a circular shape.

Purpose of the Study:

Investigate the impact of nanopore geometry on ion blockage during DNA translocation.
Compare triangular (h-BN) and circular (MoS2) nanopore shapes.

Main Methods:

Fabrication and experimentation with triangular and circular solid-state nanopores.
Measurement of ionic blockage during DNA translocation.
Development and application of a modified ionic blockage model.

Main Results:

Observed a significant geometry-dependent ion scattering effect.
Validated experimental findings with a modified ionic blockage model.
Demonstrated that pore geometry influences ion permeability and scattering.

Conclusions:

Nanopore shape critically affects ion scattering and blockage during DNA translocation.
A modified ionic blockage model accounting for geometric variations improves accuracy.
Findings guide the rational design of two-dimensional (2D) nanopores for various applications.
