Pore Size Distribution01:23

Pore Size Distribution

467
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.

Size-Exclusion Chromatography01:08

Size-Exclusion Chromatography

1.9K
In size-exclusion chromatography (SEC), also known as molecular-exclusion or gel-permeation chromatography, molecules are separated based on their sizes. This technique is important for separating large molecules such as polymers and biomolecules. The two classes of micron-sized stationary phases encountered in SEC are silica particles and cross-linked polymer resin beads. Both materials are porous, but their pore sizes vary significantly.
Silica particles offer advantages such as rigidity,...

Water and Mineral Acquisition

35.6K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Introduction to Membrane Proteins01:16

Introduction to Membrane Proteins

80.9K
The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...

States of Water01:23

States of Water

56.7K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Area of Science:

  • Materials Science
  • Environmental Science
  • Chemical Engineering

Background:

  • Offshore oil spills and oily wastewater pose significant environmental threats.
  • Conventional membranes struggle with fouling and flux-separation trade-offs in oil-water separation.

Purpose of the Study:

  • To develop a high-performance membrane for efficient oil-water separation.
  • To address limitations of conventional membranes, including poor fouling resistance and flux-separation efficiency.

Main Methods:

  • Fabrication of a hydrolyzed polyacrylonitrile by tetraethyl orthosilicate modification (HPANT) nanofibrous membrane.
  • Characterization of membrane properties, including wettability, pore size, and fouling resistance.
  • Evaluation of separation performance for immiscible mixtures and emulsions using multiscale simulations (DFT, MD, FEM).

Main Results:

  • The HPANT membrane exhibits superhydrophilicity and underwater superoleophobicity with a tunable pore size of ~20 nm.
  • Achieved high separation efficiencies: 98.29% for immiscible mixtures and 97.80% for emulsions.
  • Demonstrated excellent fouling resistance and high fluxes (e.g., 6,941.5 L·m⁻²·h⁻¹·bar⁻¹).

Conclusions:

  • The developed HPANT membrane synergistically combines selective wettability and pore-size exclusion for superior oil-water separation.
  • A stable hydration layer and tailored nanopores are key to the membrane's anti-fouling and separation capabilities.
  • This strategy offers a promising direction for designing advanced oil-water separation membranes.
