Atomic Force Microscopy01:08

Atomic Force Microscopy

4.5K
Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Atomic Orbitals

45.2K
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Intermolecular Forces

71.9K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

The Energies of Atomic Orbitals

30.3K
In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.

Area of Science:

  • Materials Science
  • Nanotechnology
  • Polymer Science

Background:

  • Current methods for shape-memory effect (SME) in micro/nano-objects use indirect macroscopic techniques.
  • These methods are applied to ensembles of objects, limiting individual analysis.

Purpose of the Study:

  • To introduce a method for controlled manipulation and SME quantification of individual micro- and nano-objects.
  • To enable thermomechanical testing analogous to macroscopic procedures.

Main Methods:

  • Utilized an atomic force microscope (AFM) to manipulate individual electro-spun poly(ether urethane) (PEU) micro/nanowires.
  • Freely suspended wires between micropillars on a silicon substrate for testing.

Main Results:

  • Achieved programming strains of 10±1% and 21±1% with successful fixation.
  • Observed near-complete shape restoration upon heating, confirming excellent SME.
  • Measured apparent recovery stresses of 1.2±0.1 MPa (microwire) and 33.3±0.1 MPa (nanowire).

Conclusions:

  • The developed AFM platform allows for precise implementation and quantification of SME in individual polymeric micro/nanosystems.
  • This method provides a universal approach for studying thermomechanically induced functions at the nanoscale.
