Waterproofing and Anti-Bacterial Admixtures in Concrete01:22

Waterproofing and Anti-Bacterial Admixtures in Concrete

134
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
Waterproofing admixtures render concrete hydrophobic,...

Surface Tension, Capillary Action, and Viscosity

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Surface Appendages of Archaea

332
Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...

Adhesion01:14

Adhesion

42.4K
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow...

Solution, Solubility, and Solubility Equilibrium
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...

Cohesion01:07

Cohesion

56.8K
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.
On a...

Summary

Mussel adhesion is hindered by surface hydration on antifouling polymers like PEG and zwitterionic materials. This strong hydration prevents dehydration, crucial for underwater glue formation, yet strong adhesion can still occur.

Area of Science:

  • Materials Science
  • Surface Chemistry
  • Biomaterials Engineering

Background:

  • Antifouling materials are vital for biomedical implants, marine coatings, biosensing, and separation membranes.
  • Poly(ethylene glycol) (PEG) and zwitterionic polymers exhibit excellent antifouling properties, attributed to strong surface hydration.
  • Developing effective underwater adhesives is challenging due to water's interference with adhesion, which often requires dehydration.

Purpose of the Study:

  • To investigate the interfacial properties between mussel adhesive plaques and antifouling materials.
  • To understand the role of surface hydration in antifouling performance and underwater adhesion.
  • To explore the mechanisms behind mussel adhesion on various surfaces.

Main Methods:

  • Sum frequency generation (SFG) vibrational spectroscopy to analyze buried interfaces.
  • Marine animal (mussel) behavior studies.
  • Adhesion measurements on different material surfaces.

Main Results:

  • PEG and zwitterionic polymers demonstrate significant surface hydration, crucial for their antifouling capabilities.
  • Mussels avoided settling on highly hydrated surfaces due to the inability to induce dehydration.
  • Control surfaces with weaker hydration allowed mussels to dehydrate the interface and foul.
  • Despite strong hydration, mussel adhesives formed strong bonds with antifouling polymers, indicating water can enhance bio-adhesion in specific cases.

Conclusions:

  • Strong surface hydration is key to the antifouling performance of PEG and zwitterionic polymers.
  • The inability to achieve interfacial dehydration on hydrated surfaces prevents mussel fouling.
  • Underwater bio-adhesion is complex, and interfacial water can, under certain conditions, promote adhesion.
