Scanning Electron Microscopy

Scanning Electron Microscopy

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.

X-ray Crystallography

X-ray Crystallography

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Background:

Characterizing nanostructures often requires stringent experimental conditions, limiting analysis in natural environments.
Small-angle scattering (SAS) using X-rays or neutrons is a key technique for analyzing nanostructures in bulk or ambient conditions, such as water at room temperature.
Advancements in synchrotron and neutron facilities enable sophisticated in situ and time-resolved SAS experiments.

Purpose of the Study:

To provide a comprehensive technical discussion of small-angle scattering (SAS).
To present SAS at a level comparable to undergraduate coverage of X-ray diffraction.
To highlight the potential of SAS for nanomaterial characterization, particularly in situ and time-resolved applications.

Main Methods:

Detailed theoretical and practical discussion of small-angle scattering principles.
Comparison of SAS with other nanostructure characterization techniques.
Exploration of SAS applications using synchrotron and neutron sources.

Main Results:

SAS is identified as a crucial method for nanostructure analysis under ambient and in situ conditions.
The development of advanced facilities enhances the capabilities of time-resolved SAS.
SAS is presented as a fundamental technique, with diffraction being a specific case.

Conclusions:

Small-angle scattering is an indispensable tool for studying nanostructures in their native states.
Despite its potential, SAS is underrepresented in general scientific education.
This work aims to bridge this gap by offering a detailed technical exposition of SAS.
