Protein-protein Interfaces02:04

Protein-protein Interfaces

14.6K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Network Covalent Solids02:18

Network Covalent Solids

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

The Fossil Record02:56

The Fossil Record

27.2K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Molecular and Ionic Solids02:54

Molecular and Ionic Solids

20.0K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Cohesion01:07

Cohesion

58.6K
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...

Area of Science:

  • Materials Science
  • Soft Matter Physics
  • Nanotechnology

Background:

  • Nanoparticles are emerging as potent adhesives for joining soft materials.
  • Understanding nanoparticle-interface interactions is crucial for developing advanced adhesives.

Purpose of the Study:

  • To investigate the contact mechanics of soft nanoparticles at interfaces between elastic surfaces.
  • To determine the factors influencing nanoparticle behavior (bridging vs. Pickering state) and substrate interaction.

Main Methods:

  • Coarse-grained molecular dynamics simulations were employed.
  • The weighted histogram analysis method (WHAM) was used to calculate the potential of mean force for substrate separation.

Main Results:

  • Nanoparticle state (bridging/Pickering) depends on size, substrate properties, and nanoparticle-substrate interactions.
  • Nanoparticle penetration is governed by size, interaction strength, and elastic properties.
  • Interface reinforcement is directly related to nanoparticle size and elastic modulus.

Conclusions:

  • Softest nanoparticles provide the most effective interface reinforcement.
  • Adhesion can be increased up to eightfold by using optimal soft nanoparticles.
