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 Absorption Spectroscopy: Atomization Methods

1.6K
Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the...

Atomic Orbitals02:44

Atomic Orbitals

43.9K
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.

Quantifying Work

24.4K
As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

Intermolecular Forces03:13

Intermolecular Forces

71.0K
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 Atomic Theory of Matter02:59

The Atomic Theory of Matter

128.0K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Tribology

Background:

  • Sliding wear is a critical issue for micro- and nano-scale devices.
  • Existing methods for measuring atomic force microscope (AFM) probe wear often require specialized equipment or continuum mechanics assumptions.
  • There is a need for simpler, more accessible wear measurement techniques.

Purpose of the Study:

  • To present a simple, purely AFM-based methodology for measuring wear in cases where the AFM probe wears to a flat plateau.
  • To enable the quantification of wear parameters without specialized equipment or complex algorithms.
  • To facilitate higher-throughput wear experiments and direct investigation into wear science.

Main Methods:

  • Developed a methodology to measure wear using only AFM.
  • Recast the rate of volume removal to depend on time-varying contact area.
  • Determined contact area using images of sharp spikes analyzed with a simple thresholding technique.
  • Validated the method using silicon probes on aluminum oxide and transmission electron microscopy.

Main Results:

  • The methodology enables rapid determination of volume lost, rate of material removal, normal stress, and interfacial shear stress.
  • The approach avoids reliance on sophisticated computer algorithms or continuum mechanics assumptions.
  • Transmission electron microscopy confirmed the method's parameters and results.

Conclusions:

  • The presented purely AFM-based methodology offers a simplified approach to wear measurement.
  • This technique can significantly enhance the throughput of wear experiments.
  • It provides a direct pathway for investigating the science of wear and its dependencies on various factors.
