Scanning Electron Microscopy01:07

Scanning Electron Microscopy

5.4K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Leaky Scanning02:28

Leaky Scanning

5.7K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Speed of a Transverse Wave01:13

Speed of a Transverse Wave

3.9K
The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

Speed of Sound in Gases01:08

Speed of Sound in Gases

4.0K
The speed of sound in a gaseous medium depends on various factors. Since gases constitute molecules that are free to move, they are highly compressible. Hence, sound waves travel slowly through gases. Thermodynamics helps us understand the relationship between pressure, volume, and temperature of gases, thus, the speed of sound in an ideal gas can be determined using the laws of thermodynamics. At the same time, Newton's laws of motion and the continuity equation of fluid dynamics also come...

Distribution of Molecular Speeds01:27

Distribution of Molecular Speeds

5.3K
The motion of molecules in a gas is random in magnitude and direction for individual molecules, but a gas of many molecules has a predictable distribution of molecular speeds. This predictable distribution of molecular speeds is known as the Maxwell-Boltzmann distribution. The distribution of molecular speeds in liquids is comparable to that of gases but not identical and can help to understand the phenomenon of the boiling and vapor pressure of a liquid. Consider that a molecule requires a...

Drag Force and Terminal Speed01:18

Drag Force and Terminal Speed

3.3K
An interesting force in everyday life is the force of drag on an object when it is moving in a fluid. Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of the object, its size, its velocity, and the fluid it is in. For most large objects, such as cyclists, cars, and baseballs, that are not moving too...

Area of Science:

  • Scanning Probe Microscopy
  • Surface Science
  • Nanotechnology

Background:

  • Scanner dynamics limit imaging speed in scanning probe microscopy (SPM).
  • Mechanical oscillations of the scanner cause image artifacts and reduce resolution, even far from resonance.
  • High scan rates exacerbate these issues, particularly over large areas.

Purpose of the Study:

  • To investigate scanner dynamics at high scan rates.
  • To develop a method for reducing oscillation-induced image artifacts.
  • To enhance the imaging speed of SPM without hardware modifications.

Main Methods:

  • Analytical and experimental investigation of scanner dynamics at high scan rates.
  • Analysis of microcantilever deflection signal frequency spectra to identify scanner eigenfrequency sidebands.
  • Development and application of a scanner dynamics-based topography reconstruction method.

Main Results:

  • At high scan speeds, frequency spectra reveal sidebands related to the scanner's eigenfrequency.
  • The proposed method successfully reconstructs surface topography by exploiting these sidebands.
  • Image artifacts were virtually eliminated for various samples at scan rates up to 59.2 Hz (4.74 mm/s) over a 40 μm × 40 μm area.
  • A nearly ten-fold increase in scan rate was achieved with legacy scanners.

Conclusions:

  • Scanner dynamics provide valuable information for artifact reduction in SPM.
  • The developed method enables significantly faster and artifact-free SPM imaging.
  • This approach offers a pathway to enhance SPM performance without requiring hardware upgrades.
